Agents of Change in Environmental Justice · Jose Ramon Becerra Vera On democratizing scienceTranscript Brian BienkowskiJose, how are you doing this morning?Jose Ramón Becerra I'm doing pretty good. How are you?Brian Bienkowski I'm doing great. And where are you this morning?Jose Ramón Becerra I am in West Lafayette, Indiana.Brian Bienkowski All right, West Lafayette, Indiana. Far away from California's inland empire where you're originally from. So I want to talk to you a little bit about the Inland Empire region. So can you tell us about this place, and perhaps how you see it may have shaped your interest in environmental justice and your research?Jose Ramón Becerra Yeah, sure. So I was born and raised in the Inland Empire. So the Inland Empire is a region in southern California. It's around 50 miles 50 miles east of Los Angeles. Really, depending on who you ask, they might define the Inland Empire differently. So some folks will conceptualize it as the entirety of San Bernardino and Riverside counties. But for me, and a lot of people in my community, we think about it as the Valley portion that's surrounded by this mountain and stone geography. Some things that I love about the places that like, depending on the city that you're at, you're probably like 10 to 15 minutes away from like a nice hike when you go up to the mountains. And you're also –depending on the traffic– only, like 40 minutes to an hour and a half away from the nearest beach. It's a primarily Latino community, who live and work there each day. So there's a lot of great food all the time. I think it's a vibrant community, I love it. And how it shapes my interest in environmental justice and research, while my whole dissertation project is kind of dedicated to looking at air pollution exposure in the in the Inland Empire region. So I would say that it shapes my projects completely. From my research questions to my field site, to the people who I work with. I don't think this came around until I was in college, though. So because I guess growing up the signs of pollution that I see now, like the diesel trucks driving by or the wildfire smoke and stuff like that was just kind of part of the ordinary environment. So it wasn't until I started going to college and learning that like, not everybody in your community should have or like, asthma rates shouldn't be that high for everyone. So that's not it wasn't until I actually got into college I started learning about the issues that I'll see on a day-to-day basis as environmental and justices.Brian Bienkowski Was it a culture shock moving to Indiana?Jose Ramón Becerra Yeah, it was 100% Was it was the first time I was out of the area. So I was like I said, born and raised there. The only other places I really frequency, the war Los Angeles area to visit family and friends or my parents hometown in Tepatitlán, Jalisco, in Mexico. So I was just back and forth in these places all the time. And outside of that, yeah, I just hadn't been outside of like a few days. Maybe I hadn't been outside of California too much. California or Mexico.Brian Bienkowski So before we get And into some of the research you've been doing about the Inland Empire and where you're at now, what is the moment or event that helped shape your identity up to this point?Jose Ramón Becerra You know, funny enough, it was actually coming to Indiana for my PhD, or for my graduate studies for my Masters, and now my PhD. So like I said, I was in the Inland Empire for so long. The only other places I really frequented were Mexico. And so I was really just kind of in the middle of like my culture every day. So whether that's like Mexican culture, or Chicano culture, or just Southern California, Inland Empire culture, I was just immersed in it 24/7. And it was kind of like what they say like, culture is kind of like water for a fish. So it wasn't until I stepped out of there started living out here that I started missing so many things about like, what I see as my identity now, which is like the music, how people dress, how they talk, just the... you know, how people engage, the language and stuff like that. So yeah, oddly enough, it wasn't until I came out here to Indiana that I started really reflecting on who I was and how I was connected to my communities and stuff like that. So yeah, I think that that moment, just living out here has really solidified who I am.Brian Bienkowski I think travel is good for that people always talk about travel in terms of introducing you to other cultures, which is obviously I think, a net good, it's a good thing. But I can say when my wife and I we live in the Upper Peninsula, Michigan, and we are very, we are very Northern Great Lakes people. And when we were in New York City for a week, which I love, you know, it's just such a vibrant place, so fun to visit. And oh my gosh, did we feel like fish out of water, though! you know, we move very slow, we talk very slow, we're in people's way. So you know, I do think there is something to be exposed to other cultures, but also it kind of reaffirms who you are, and your own culture, as you mentioned. So I want to talk about your PhD work. But while you've been doing that, during the PhD work, you've also worked as a fellow in nonprofits, including Elevate in Chicago and for the EPA, the federal agency. So what did these experiences teach you about the value of kind of qualitative versus quantitative data? And do you have any examples?Jose Ramón Becerra Yeah, so I've been lucky enough to work with, and not just with them, I've been lucky enough to work with government, with nonprofits, with environmental justice organizations, and activists, and also just community members in different research sites. And I think the first thing I want to highlight is that there are individuals from all these different places who are doing such meaningful work. They're all dedicated to making environmental justice action happen, and essentially to alleviate disproportionate exposure to pollution. And so while this is happening, something that I kind of saw when I started reflecting on my ethnographic notes, so when I was collecting data for my own dissertation study, while talking to all these people and working with them through fellowships, was that just the underlying fact that quantitative data holds more value in policy arenas than qualitative data. And oftentimes, this is for good reason. So if an agency is going to ban a chemical, for example, they have to show that there's a causal relationship between like that chemical exposure and the health detriment. But at the same time, like an example of this can be like a community that gets together to push against a factory that's emitting whatever type of pollution. Their experiences and the qualitative data they come up with –and even if they organize–, is not going to make environmental change. Oftentimes, what happens is that this causes attention to whatever issues going on, it pulls in scientists and other people to do research and to do those quantitative studies to then make change. But unfortunately, what's happening is that while this science is getting done, or this quantitative data collection is getting done, and analysis and reports are getting written, it's a really slow movement, science is slow in many of those situations, and all the while people are being exposed to that same pollution. So there's no protections that are being offered, even when they present that qualitative information to whoever triggers like these other responses.Brian Bienkowski And so I don't want to put words in your mouth, but this qualitative data that mean these can be things like surveys, personal experiences, and in some cases, you know, in my profession, it's not it's not science, but in journalism, I mean, we look at storytelling and telling these people stories and narratives and communities as kind of a form of qualitative data. And and I think you can, you can tell that that can be really powerful, but as you said, the turns of the regulatory environment and science can move slowly sometimes. Jose, I should have set the stage before that question for you. listeners, what exactly you mentioned air pollution and kind of this data collection. Can you tell us what kind of science and research you're doing?Jose Ramón Becerra Yeah, so I do a lot of anthropology. So I'm in nog refer that means that I, like immerse myself in a community and collect a lot of qualitative data. So I do things like, participant observation. So I do observations and take notes on that. I do a lot of interviews with people. And at the same time, I'm doing community science, where I'm using portable pollution monitors to collect data with people who are from the Inland Empire. So I'm investigating through the frameworks of like political ecology, which is the idea that we're looking at the social-political dimensions of environmental change throughout time. So is like capitalism driving this change? What are the policies driving this change in? How does an environment become toxic, and I'm also really interested in who's exposed to pollution. So that's the environmental justice dimension of it that I include into my research.Brian Bienkowski So I want to talk more about the environmental concerns in the Inland Empire region. I think most of us when we hear warehouses, we don't associate them with pollution, we think of a big Amazon warehouse or something. But can you explain why this dense network of warehouses that exists there in the Inland Empire, what it looks like and what the environmental concerns and impacts are?Jose Ramón Becerra Yeah, so it's really interesting, you bring that up, because... so growing up, I'm from a city, Ontario, California, that's within the Inland Empire. And we have some of the highest warehouse density there. But I never really connected how they were, like sources of pollution. In my head, I was like, "Well, are they producing something in there that's, you know, driving up, like pollution in the region or whatnot?" But so if you look at the larger region, we have over 1 billion square feet of warehouses there. And like I said, we're in close proximity to Los Angeles. So what happens is that each day, we get ships full of containers that have goods inside of them, those containers get hauled eastward into the Inland Empire, it's estimated that 40% of all goods that come into the nation go through the Inland Empire, then the warehouses are locations where workers unload the containers, then later, repackage them and send them out to the rest of the nation, surrounding communities, via rail yard, diesel truck, and airplanes. And all of this transportation just increases massive amounts of pollution in the region that's been trapped by that mountainous dome geography I talked about a little bit earlier.Brian Bienkowski Can you talk about that geography and why it's problematic and how it traps pollutants?Jose Ramón Becerra Yeah, so if you look at a map for San Bernardino and Riverside County, you'll see that it's like this, this mountain that's connecting... this mountain range that connects the Los Angeles area to the Inland Empire. But then there's like this other barrier, kind of east and south of it, so all that, like mountainous dome geography traps pollution there, that comes from Los Angeles, that comes from the warehouse industry. And at the same time, we have with climate change a lot of more wildfires that burn more intensely and more frequent in the region. So even the wildfire smoke accumulates in that same space.Brian Bienkowski So otherwise, the air pollutants would be able to kind of push on into the atmosphere, but here they're getting trapped and kind of hovering above the community, right. So in this battle of residence against developers that I've talked to you about separately, and I know you're thinking and writing about these things, in that region, you say developers are often using outdated evidence and stationary monitor data. So what is your research shown about the monitoring data used and why it can be misleading?Jose Ramón Becerra Yeah, so the whole idea about outdated evidence came from when I was seeing participant observation. So I was following this, this applicant who was trying to build another warehouse in the Bloomington area, which is an unincorporated area in the Inland Empire. And when they were applying to do this, there was moments for the public to gather and kind of have their own comments about the warehouse, and if they wanted, they want to invite it in or not. And so the community was really great at organizing environmental justice organizations gathered the community, there's a lot of folks who are concerned individually. So a lot of folks were going up and giving their testimonials and they were like really talking about how air pollution had been damaging their health or the health of their children, for example, or even talking about like the cancer rates in the area. And in one of those testimonials, one of the one of the people who were, one of the persons talking kind of hinted at the fact that the environmental impact report was misleading. So it was through this person's own analysis and like reading the document that they were identifying that the data that they were using was outdated. And this got me really thinking about things like data sources, and scientific instrumentation, and even analysis. So depending on, like, how you're making your analysis, where the data is coming from, there could be a lot of things that are misleading when we're thinking about personal exposure. And so another thing that I'm really looking at is the differences between, or the limitations, at least, of stationary monitor data. So in places like the Inland Empire, especially where the environment is quickly changing, so we have warehouses that are built within months sometimes. And so the macro geography is constantly changing, people aren't just fixed in one location at all times. So as you know, like throughout our day, depending on our job, depending on what our daily activities look like, we're inside of houses, outdoors, in apartments, in your job side, on the street, driving through traffic, and all these different things are going to expose you to different levels of pollution. So just thinking about how there's these spatial temporal elements of people's activity is important how micro geography –so like the built environment, and how it's changing– also impacts different levels of exposure in the same region.Brian Bienkowski So I live in Sault Sainte Marie Michigan, and across the river is Sault Sainte Marie, Canada, same same name, different city, and there's a massive steel plant, and they all have their air monitoring at one time was placed, northwest of the building, and we live by Lake Superior. So the winds are always coming from the Northwest. And maybe I have this backwards. Basically, they had these monitors in a place where it was never capturing what was actually the air, you know, the wind was coming from the other direction. And so these stationary monitors were just completely they were really useless for a long time. And that's what the federal government relied on, it was industry data. So in your case, how do you how do you account for these micro geographies? Are you working with citizens or residents to try to do some monitoring that you feel is better and more accurate of what's actually happening?Jose Ramón Becerra So one of the projects that I'm doing, and I'm going to be doing from August to December this year, is working with community scientists to carry portable pollution monitors that are GPS-enabled. And this is a collaboration with Dr. Uman Park at University of Connecticut, that and so the project basically is going to be trying to account for how people navigate space. And while they carry these monitors, I'm gonna be able to tell how much pollution they're exposed to, throughout their daily activities, I'm also going to be in the community working with them to train them how to take behavioral notes, and this is going to be done through Qualtrics. So it's a widget that I'm gonna download into their phone, if they want to take notes on their cell phone, or if they want to use a voice recorder, they have that option. And then we're also taking demographic surveys. So that way we can make an analysis when we have enough data to show how social demographics might influence things like access to different types of jobs, and those jobs put you at different levels of exposure compared to you know, whatever, like just depending on the job, you might be exposed to different levels of exposure. So we're going to be really thinking critically about how access to job and just access to and wasted navigate space are kind of shaped by social demographics that are like embedded in deeper roots of like racial capitalism in the region.Brian Bienkowski How do you see these efforts as democratizing science in the region?Jose Ramón Becerra Yeah, so, um, I think that I see this effort is democratizing science, and that the first thing is that it's giving something that's legible for these policy arenas. When people talk about their experiences, like we should value them, that qualitative information should be valued. But for now, I think that it's important to still equip people with the scientific instrumentation in order to make their claims legible. So I think that I'm trying to join that qualitative aspect with the more quantitative and spatial data so that way, when it comes to people advocating for themselves, they have the data that's seen in these policy arenas. And at the same time, something that I see happen when people are advocating for themselves through testimonials is that they're up against people who are considered experts for the quantitative data. And by letting them collect data, it's kind of making them the experts. So they're learning why they're collecting data, how the monitors work, what kind of data they're collecting. So in their own way, they're becoming experts, not just of their own experiences, but also of the data collection process. And so in these two ways, I think that it's it's an effort to democratize science in the community.Brian Bienkowski I really liked that idea that they're already experts have their own experience. And this is making them experts in the data collection. That's a really cool way of thinking about it. I like that. Are you getting pushback in the region at all? Or is there pushback with this kind of economic versus or environmental thing? I have to imagine a good number of the residents work in many of these warehouses and provide for their families. So what's that kind of balancing act been like?Jose Ramón Becerra Yeah, I definitely see this, even in the Commission hearings I mentioned earlier, where there is a lot of people from the community who are trying to push against the warehouse, industry and just development in general. But then there's other people who are like in construction, who might be employed to build these warehouses that are kind of advocating for those jobs, because they're going to be local. They don't have to drive up like to Northern California, for example, to you know, do their job, tey could be next to their family. So there is pushback in that sense. But I think, in general, what I've seen is that people are really concerned with the type of jobs that these warehouses even provide. So what happens in the region is that many of the jobs available there are through agencies. So if you want a job there, you could start by going to an agency, and then the agency, like, recommends you to a warehouse and you start working there, but you're not actually hired through the company. So not being hired to the company has its own consequences, like there's limited liability they're accountable for, sometimes they don't have to provide health insurance and things like that, and you get lower pay. So when it comes to actual warehouse workers, I think that they know that these warehouses aren't necessarily like the like, what they want for their own future for their children's future. So I think that there's also a lot of people who are advocating for like, a different type of industry to, you know, come into the area.Brian Bienkowski I know personally, what I've written about the steel plant I mentioned earlier, you know, I have family who knows workers there and stuff around here. And the idea is not that we are, or I should I should speak for myself, you know, that we're not blaming the workers here. You know, the workers deserve protection, they deserve knowledge, they deserve data. And a lot of times, it's the people who have power and money and who are running these plants or warehouses or, you know, fleets of trucks that have the opportunity to reduce pollution, and they're not doing it because of various reasons. So I always try to make that clear that this isn't, we're not attacking the workers, you know, that it's definitely not their fault that, you know, this is this is goes higher than that to the regulatory, and kind of corporate level of a lot of these organizations. So what what tips would you have for other researchers that want to center communities like this in their own work?Jose Ramón Becerra Yeah, so I think that, um, it's super important to be in communication with the community, and ask them like what they need, even if that comes at the expense of modifying your research project or question, I think that if you want to center the community, the kind of data collection you do the type of analysis and all that should have them involved in they should have a say in like the kind of research you do, especially if you're going into this community fresh. And another thing, if you're doing environmental-justice-based research is to reach out to the local organizations, they are likely already doing a lot of wonderful work. They're connected to the community, they're also connected to policymakers and lawyers, and all that kind of stuff. So starting with them and talking to them having conversations and trying to be as transparent as possible can, in my opinion, take you a very long way in centering communities in your research.Brian Bienkowski I assume you still have family in the region. What's their reaction been to your to your research and your work? Have you have you taught them some things that they maybe didn't know before about where where they're from?Jose Ramón Becerra You know, they I think so. But I think they definitely teach me just as much and that's something I keep learning that like, when I come back home with the instruments, my family, my friends are super excited about it. And they helped me like even theorize for example, sometimes I'm writing a paper and I call them about like an interview we did or or like what their opinion is about, like, the relationship between something really like abstract like capitalism and pollution exposure. And they're super good at like teaching me what their perspective is. And a lot of the times it helps me even like formulate a paper on working on or, or write a piece of it and stuff like that. So I think that if anything there, they just keep teaching me and teaching me more and more stuff.Brian Bienkowski So you mentioned some of you know, some citizen science projects that you have upcoming here in a couple months. You know, maybe it's that or beyond that, what would you like to see change about the air pollution research field kind of broadly? And how do you see yourself as part of that change?Jose Ramón Becerra I think that something I would love to see is more community-based work. I think that, um, like, if we go on Google Scholar, for example, and we search up air pollution, we're gonna see 1000s of studies proving that air pollution is bad for health. And similarly, we'll see 1000s of studies showing that pollution is like, disproportionately distributed across national and global scales. So we know that these things are bad. And I think something important to look at would be community engagement, and also finding ways to merge and bring value to qualitative data and quantitative data together. I think that's what I would love to see. And I think that's what I'm trying to do with the projects that I'm engaged with as someone who's doing both very qualitative and quantitative data collection in my study. So I think that's that's my role in what I would love to see more more community based work.Brian Bienkowski What are you optimistic about?Jose Ramón Becerra I am very optimistic about a lot of the work that environmental justice organizations are already doing. Like in my hometown, or in the Inland Empire. There's people's collective for environmental justice, who are like excellent researchers, policy analyst and advocates for the community. And what I really love to see is that a lot of the folks who I've talked to, and the work that they're doing comes from, like, they're like they come from their hometown. So they're really invested in the type of work that they do. So I'm, I'm really optimistic about that. And it's inspiring to me. And I hope that future generations are able to see all this kind of work that's happening locally, and like in other communities, too. And you know, just find that inspiration and keep pushing forward for whatever cause that they're passionate about.Brian Bienkowski Well, Jose, this has been so so wonderful, I really love hearing about people's hometown, especially when they're very far from where I'm from. And when we were in person, I got to talk to you a little bit about where you're from as well. And it's just really great to hear about the research you're doing. So now I have a few fun questions before we get you out of here. You can just answer these these next three with just one word or short phrase. My first concert wasJose Ramón Becerra Wu Tang Clan.Brian Bienkowski Oh my god!Jose Ramón Becerra yeah, I, I think I also I had gone to other ones for my parents, I think and then like backyard concerts and stuff like that. But the first one like I paid for, and I was really excited about was Wu Tang.Brian Bienkowski Oh, my, oh, my goodness. So another peek behind the curtain. Jose and I talked hip hop a little bit when we were meeting in person. So Wu Tang, being your first concert is is quite something that's very cool. If I have a whole day off, I am likelyJose Ramón Becerra To invite everyone over for a carne asada.Brian Bienkowski You sound like an extrovert. I would be by myself reading a book. So one of my all time favorite movies isJose Ramón Becerra Friday.Brian Bienkowski Oh, man, me too.Jose Ramón Becerra Oh, I really, really love that movieBrian Bienkowski very much. So when I was yes, that was a that was a must watch, I would say between the ages of like, oh god, 16 to 25. I'd watch it a few times a year every year. Chris Tucker's is so fantastic in it. Well, thank you so much again, Jose, this has been a whole lot of fun. And before we get you out of here, what is the last book you read for fun? And you don't have to confine yourself to one word or a phrase here.Jose Ramón Becerra Yeah. All right. So I have like the nerdy answer to that, because I'm truly passionate about my research in my hometown. So there's a professor there named Dr. Juan de Lada, who wrote a book inland shift. And he's also like a hometown scholar that writes about the Inland Empire. So I really love that book. But something that I've read, that's just fun and not connected to my research, because I really don't read that much outside of, like, for research purposes, would probably be back in the day elementary school like Captain Underpants I really loved like the flip action. So surely that was like the last fun fun book I read, like just for fun.Brian Bienkowski Well, Jose, thank you so much. You're doing such incredible work. I'm so glad you're part of this cohort and have a great rest of your day.Jose Ramón Becerra Thank you so much.Brian Bienkowski All right. That's a wrap for this week, folks. I hope you enjoyed my conversation with Jose I think I need to dust off the old Friday DVD this weekend and give it a watch.

Agents of Change in Environmental Justice · Jose Ramon Becerra Vera On democratizing scienceTranscript Brian BienkowskiJose, how are you doing this morning?Jose Ramón Becerra I'm doing pretty good. How are you?Brian Bienkowski I'm doing great. And where are you this morning?Jose Ramón Becerra I am in West Lafayette, Indiana.Brian Bienkowski All right, West Lafayette, Indiana. Far away from California's inland empire where you're originally from. So I want to talk to you a little bit about the Inland Empire region. So can you tell us about this place, and perhaps how you see it may have shaped your interest in environmental justice and your research?Jose Ramón Becerra Yeah, sure. So I was born and raised in the Inland Empire. So the Inland Empire is a region in southern California. It's around 50 miles 50 miles east of Los Angeles.

And you're also –depending on the traffic– only, like 40 minutes to an hour and a half away from the nearest beach. It's a primarily Latino community, who live and work there each day.

And how it shapes my interest in environmental justice and research, while my whole dissertation project is kind of dedicated to looking at air pollution exposure in the in the Inland Empire region. So I would say that it shapes my projects completely. From my research questions to my field site, to the people who I work with. I don't think this came around until I was in college, though. So because I guess growing up the signs of pollution that I see now, like the diesel trucks driving by or the wildfire smoke and stuff like that was just kind of part of the ordinary environment. So it wasn't until I started going to college and learning that like, not everybody in your community should have or like, asthma rates shouldn't be that high for everyone. So that's not it wasn't until I actually got into college I started learning about the issues that I'll see on a day-to-day basis as environmental and justices.Brian Bienkowski Was it a culture shock moving to Indiana?Jose Ramón Becerra Yeah, it was 100% Was it was the first time I was out of the area. So I was like I said, born and raised there. The only other places I really frequency, the war Los Angeles area to visit family and friends or my parents hometown in Tepatitlán, Jalisco, in Mexico. So I was just back and forth in these places all the time. And outside of that, yeah, I just hadn't been outside of like a few days. Maybe I hadn't been outside of California too much. California or Mexico.Brian Bienkowski So before we get And into some of the research you've been doing about the Inland Empire and where you're at now, what is the moment or event that helped shape your identity up to this point?Jose Ramón Becerra You know, funny enough, it was actually coming to Indiana for my PhD, or for my graduate studies for my Masters, and now my PhD. So like I said, I was in the Inland Empire for so long. The only other places I really frequented were Mexico. And so I was really just kind of in the middle of like my culture every day. So whether that's like Mexican culture, or Chicano culture, or just Southern California, Inland Empire culture, I was just immersed in it 24/7. And it was kind of like what they say like, culture is kind of like water for a fish. So it wasn't until I stepped out of there started living out here that I started missing so many things about like, what I see as my identity now, which is like the music, how people dress, how they talk, just the... you know, how people engage, the language and stuff like that. So yeah, oddly enough, it wasn't until I came out here to Indiana that I started really reflecting on who I was and how I was connected to my communities and stuff like that. So yeah, I think that that moment, just living out here has really solidified who I am.Brian Bienkowski I think travel is good for that people always talk about travel in terms of introducing you to other cultures, which is obviously I think, a net good, it's a good thing. But I can say when my wife and I we live in the Upper Peninsula, Michigan, and we are very, we are very Northern Great Lakes people. And when we were in New York City for a week, which I love, you know, it's just such a vibrant place, so fun to visit. And oh my gosh, did we feel like fish out of water, though! you know, we move very slow, we talk very slow, we're in people's way. So you know, I do think there is something to be exposed to other cultures, but also it kind of reaffirms who you are, and your own culture, as you mentioned. So I want to talk about your PhD work. But while you've been doing that, during the PhD work, you've also worked as a fellow in nonprofits, including Elevate in Chicago and for the EPA, the federal agency. So what did these experiences teach you about the value of kind of qualitative versus quantitative data? And do you have any examples?Jose Ramón Becerra Yeah, so I've been lucky enough to work with, and not just with them, I've been lucky enough to work with government, with nonprofits, with environmental justice organizations, and activists, and also just community members in different research sites. And I think the first thing I want to highlight is that there are individuals from all these different places who are doing such meaningful work. They're all dedicated to making environmental justice action happen, and essentially to alleviate disproportionate exposure to pollution. And so while this is happening, something that I kind of saw when I started reflecting on my ethnographic notes, so when I was collecting data for my own dissertation study, while talking to all these people and working with them through fellowships, was that just the underlying fact that quantitative data holds more value in policy arenas than qualitative data. And oftentimes, this is for good reason. So if an agency is going to ban a chemical, for example, they have to show that there's a causal relationship between like that chemical exposure and the health detriment. But at the same time, like an example of this can be like a community that gets together to push against a factory that's emitting whatever type of pollution. Their experiences and the qualitative data they come up with –and even if they organize–, is not going to make environmental change. Oftentimes, what happens is that this causes attention to whatever issues going on, it pulls in scientists and other people to do research and to do those quantitative studies to then make change. But unfortunately, what's happening is that while this science is getting done, or this quantitative data collection is getting done, and analysis and reports are getting written, it's a really slow movement, science is slow in many of those situations, and all the while people are being exposed to that same pollution. So there's no protections that are being offered, even when they present that qualitative information to whoever triggers like these other responses.Brian Bienkowski And so I don't want to put words in your mouth, but this qualitative data that mean these can be things like surveys, personal experiences, and in some cases, you know, in my profession, it's not it's not science, but in journalism, I mean, we look at storytelling and telling these people stories and narratives and communities as kind of a form of qualitative data. And and I think you can, you can tell that that can be really powerful, but as you said, the turns of the regulatory environment and science can move slowly sometimes. Jose, I should have set the stage before that question for you. listeners, what exactly you mentioned air pollution and kind of this data collection. Can you tell us what kind of science and research you're doing?Jose Ramón Becerra Yeah, so I do a lot of anthropology. So I'm in nog refer that means that I, like immerse myself in a community and collect a lot of qualitative data. So I do things like, participant observation. So I do observations and take notes on that. I do a lot of interviews with people. And at the same time, I'm doing community science, where I'm using portable pollution monitors to collect data with people who are from the Inland Empire. So I'm investigating through the frameworks of like political ecology, which is the idea that we're looking at the social-political dimensions of environmental change throughout time. So is like capitalism driving this change? What are the policies driving this change in? How does an environment become toxic, and I'm also really interested in who's exposed to pollution. So that's the environmental justice dimension of it that I include into my research.Brian Bienkowski So I want to talk more about the environmental concerns in the Inland Empire region. I think most of us when we hear warehouses, we don't associate them with pollution, we think of a big Amazon warehouse or something. But can you explain why this dense network of warehouses that exists there in the Inland Empire, what it looks like and what the environmental concerns and impacts are?Jose Ramón Becerra Yeah, so it's really interesting, you bring that up, because... so growing up, I'm from a city, Ontario, California, that's within the Inland Empire. And we have some of the highest warehouse density there. But I never really connected how they were, like sources of pollution. In my head, I was like, "Well, are they producing something in there that's, you know, driving up, like pollution in the region or whatnot?" But so if you look at the larger region, we have over 1 billion square feet of warehouses there. And like I said, we're in close proximity to Los Angeles. So what happens is that each day, we get ships full of containers that have goods inside of them, those containers get hauled eastward into the Inland Empire, it's estimated that 40% of all goods that come into the nation go through the Inland Empire, then the warehouses are locations where workers unload the containers, then later, repackage them and send them out to the rest of the nation, surrounding communities, via rail yard, diesel truck, and airplanes. And all of this transportation just increases massive amounts of pollution in the region that's been trapped by that mountainous dome geography I talked about a little bit earlier.Brian Bienkowski Can you talk about that geography and why it's problematic and how it traps pollutants?Jose Ramón Becerra Yeah, so if you look at a map for San Bernardino and Riverside County, you'll see that it's like this, this mountain that's connecting... this mountain range that connects the Los Angeles area to the Inland Empire. But then there's like this other barrier, kind of east and south of it, so all that, like mountainous dome geography traps pollution there, that comes from Los Angeles, that comes from the warehouse industry. And at the same time, we have with climate change a lot of more wildfires that burn more intensely and more frequent in the region. So even the wildfire smoke accumulates in that same space.Brian Bienkowski So otherwise, the air pollutants would be able to kind of push on into the atmosphere, but here they're getting trapped and kind of hovering above the community, right. So in this battle of residence against developers that I've talked to you about separately, and I know you're thinking and writing about these things, in that region, you say developers are often using outdated evidence and stationary monitor data. So what is your research shown about the monitoring data used and why it can be misleading?Jose Ramón Becerra Yeah, so the whole idea about outdated evidence came from when I was seeing participant observation. So I was following this, this applicant who was trying to build another warehouse in the Bloomington area, which is an unincorporated area in the Inland Empire. And when they were applying to do this, there was moments for the public to gather and kind of have their own comments about the warehouse, and if they wanted, they want to invite it in or not. And so the community was really great at organizing environmental justice organizations gathered the community, there's a lot of folks who are concerned individually. So a lot of folks were going up and giving their testimonials and they were like really talking about how air pollution had been damaging their health or the health of their children, for example, or even talking about like the cancer rates in the area. And in one of those testimonials, one of the one of the people who were, one of the persons talking kind of hinted at the fact that the environmental impact report was misleading. So it was through this person's own analysis and like reading the document that they were identifying that the data that they were using was outdated. And this got me really thinking about things like data sources, and scientific instrumentation, and even analysis. So depending on, like, how you're making your analysis, where the data is coming from, there could be a lot of things that are misleading when we're thinking about personal exposure. And so another thing that I'm really looking at is the differences between, or the limitations, at least, of stationary monitor data. So in places like the Inland Empire, especially where the environment is quickly changing, so we have warehouses that are built within months sometimes. And so the macro geography is constantly changing, people aren't just fixed in one location at all times. So as you know, like throughout our day, depending on our job, depending on what our daily activities look like, we're inside of houses, outdoors, in apartments, in your job side, on the street, driving through traffic, and all these different things are going to expose you to different levels of pollution. So just thinking about how there's these spatial temporal elements of people's activity is important how micro geography –so like the built environment, and how it's changing– also impacts different levels of exposure in the same region.Brian Bienkowski So I live in Sault Sainte Marie Michigan, and across the river is Sault Sainte Marie, Canada, same same name, different city, and there's a massive steel plant, and they all have their air monitoring at one time was placed, northwest of the building, and we live by Lake Superior. So the winds are always coming from the Northwest. And maybe I have this backwards. Basically, they had these monitors in a place where it was never capturing what was actually the air, you know, the wind was coming from the other direction. And so these stationary monitors were just completely they were really useless for a long time. And that's what the federal government relied on, it was industry data. So in your case, how do you how do you account for these micro geographies? Are you working with citizens or residents to try to do some monitoring that you feel is better and more accurate of what's actually happening?Jose Ramón Becerra So one of the projects that I'm doing, and I'm going to be doing from August to December this year, is working with community scientists to carry portable pollution monitors that are GPS-enabled. And this is a collaboration with Dr. Uman Park at University of Connecticut, that and so the project basically is going to be trying to account for how people navigate space. And while they carry these monitors, I'm gonna be able to tell how much pollution they're exposed to, throughout their daily activities, I'm also going to be in the community working with them to train them how to take behavioral notes, and this is going to be done through Qualtrics. So it's a widget that I'm gonna download into their phone, if they want to take notes on their cell phone, or if they want to use a voice recorder, they have that option. And then we're also taking demographic surveys. So that way we can make an analysis when we have enough data to show how social demographics might influence things like access to different types of jobs, and those jobs put you at different levels of exposure compared to you know, whatever, like just depending on the job, you might be exposed to different levels of exposure. So we're going to be really thinking critically about how access to job and just access to and wasted navigate space are kind of shaped by social demographics that are like embedded in deeper roots of like racial capitalism in the region.Brian Bienkowski How do you see these efforts as democratizing science in the region?Jose Ramón Becerra Yeah, so, um, I think that I see this effort is democratizing science, and that the first thing is that it's giving something that's legible for these policy arenas. When people talk about their experiences, like we should value them, that qualitative information should be valued. But for now, I think that it's important to still equip people with the scientific instrumentation in order to make their claims legible. So I think that I'm trying to join that qualitative aspect with the more quantitative and spatial data so that way, when it comes to people advocating for themselves, they have the data that's seen in these policy arenas. And at the same time, something that I see happen when people are advocating for themselves through testimonials is that they're up against people who are considered experts for the quantitative data. And by letting them collect data, it's kind of making them the experts. So they're learning why they're collecting data, how the monitors work, what kind of data they're collecting. So in their own way, they're becoming experts, not just of their own experiences, but also of the data collection process. And so in these two ways, I think that it's it's an effort to democratize science in the community.Brian Bienkowski I really liked that idea that they're already experts have their own experience. And this is making them experts in the data collection. That's a really cool way of thinking about it. I like that. Are you getting pushback in the region at all? Or is there pushback with this kind of economic versus or environmental thing? I have to imagine a good number of the residents work in many of these warehouses and provide for their families. So what's that kind of balancing act been like?Jose Ramón Becerra Yeah, I definitely see this, even in the Commission hearings I mentioned earlier, where there is a lot of people from the community who are trying to push against the warehouse, industry and just development in general. But then there's other people who are like in construction, who might be employed to build these warehouses that are kind of advocating for those jobs, because they're going to be local. They don't have to drive up like to Northern California, for example, to you know, do their job, tey could be next to their family. So there is pushback in that sense. But I think, in general, what I've seen is that people are really concerned with the type of jobs that these warehouses even provide. So what happens in the region is that many of the jobs available there are through agencies. So if you want a job there, you could start by going to an agency, and then the agency, like, recommends you to a warehouse and you start working there, but you're not actually hired through the company. So not being hired to the company has its own consequences, like there's limited liability they're accountable for, sometimes they don't have to provide health insurance and things like that, and you get lower pay. So when it comes to actual warehouse workers, I think that they know that these warehouses aren't necessarily like the like, what they want for their own future for their children's future. So I think that there's also a lot of people who are advocating for like, a different type of industry to, you know, come into the area.Brian Bienkowski I know personally, what I've written about the steel plant I mentioned earlier, you know, I have family who knows workers there and stuff around here. And the idea is not that we are, or I should I should speak for myself, you know, that we're not blaming the workers here. You know, the workers deserve protection, they deserve knowledge, they deserve data. And a lot of times, it's the people who have power and money and who are running these plants or warehouses or, you know, fleets of trucks that have the opportunity to reduce pollution, and they're not doing it because of various reasons. So I always try to make that clear that this isn't, we're not attacking the workers, you know, that it's definitely not their fault that, you know, this is this is goes higher than that to the regulatory, and kind of corporate level of a lot of these organizations. So what what tips would you have for other researchers that want to center communities like this in their own work?Jose Ramón Becerra Yeah, so I think that, um, it's super important to be in communication with the community, and ask them like what they need, even if that comes at the expense of modifying your research project or question, I think that if you want to center the community, the kind of data collection you do the type of analysis and all that should have them involved in they should have a say in like the kind of research you do, especially if you're going into this community fresh. And another thing, if you're doing environmental-justice-based research is to reach out to the local organizations, they are likely already doing a lot of wonderful work. They're connected to the community, they're also connected to policymakers and lawyers, and all that kind of stuff. So starting with them and talking to them having conversations and trying to be as transparent as possible can, in my opinion, take you a very long way in centering communities in your research.Brian Bienkowski I assume you still have family in the region. What's their reaction been to your to your research and your work? Have you have you taught them some things that they maybe didn't know before about where where they're from?Jose Ramón Becerra You know, they I think so. But I think they definitely teach me just as much and that's something I keep learning that like, when I come back home with the instruments, my family, my friends are super excited about it. And they helped me like even theorize for example, sometimes I'm writing a paper and I call them about like an interview we did or or like what their opinion is about, like, the relationship between something really like abstract like capitalism and pollution exposure. And they're super good at like teaching me what their perspective is. And a lot of the times it helps me even like formulate a paper on working on or, or write a piece of it and stuff like that. So I think that if anything there, they just keep teaching me and teaching me more and more stuff.Brian Bienkowski So you mentioned some of you know, some citizen science projects that you have upcoming here in a couple months. You know, maybe it's that or beyond that, what would you like to see change about the air pollution research field kind of broadly? And how do you see yourself as part of that change?Jose Ramón Becerra I think that something I would love to see is more community-based work. I think that, um, like, if we go on Google Scholar, for example, and we search up air pollution, we're gonna see 1000s of studies proving that air pollution is bad for health. And similarly, we'll see 1000s of studies showing that pollution is like, disproportionately distributed across national and global scales. So we know that these things are bad. And I think something important to look at would be community engagement, and also finding ways to merge and bring value to qualitative data and quantitative data together. I think that's what I would love to see. And I think that's what I'm trying to do with the projects that I'm engaged with as someone who's doing both very qualitative and quantitative data collection in my study. So I think that's that's my role in what I would love to see more more community based work.Brian Bienkowski What are you optimistic about?Jose Ramón Becerra I am very optimistic about a lot of the work that environmental justice organizations are already doing. Like in my hometown, or in the Inland Empire. There's people's collective for environmental justice, who are like excellent researchers, policy analyst and advocates for the community. And what I really love to see is that a lot of the folks who I've talked to, and the work that they're doing comes from, like, they're like they come from their hometown. So they're really invested in the type of work that they do. So I'm, I'm really optimistic about that. And it's inspiring to me. And I hope that future generations are able to see all this kind of work that's happening locally, and like in other communities, too. And you know, just find that inspiration and keep pushing forward for whatever cause that they're passionate about.Brian Bienkowski Well, Jose, this has been so so wonderful, I really love hearing about people's hometown, especially when they're very far from where I'm from. And when we were in person, I got to talk to you a little bit about where you're from as well. And it's just really great to hear about the research you're doing. So now I have a few fun questions before we get you out of here. You can just answer these these next three with just one word or short phrase. My first concert wasJose Ramón Becerra Wu Tang Clan.Brian Bienkowski Oh my god!Jose Ramón Becerra yeah, I, I think I also I had gone to other ones for my parents, I think and then like backyard concerts and stuff like that. But the first one like I paid for, and I was really excited about was Wu Tang.Brian Bienkowski Oh, my, oh, my goodness. So another peek behind the curtain. Jose and I talked hip hop a little bit when we were meeting in person. So Wu Tang, being your first concert is is quite something that's very cool. If I have a whole day off, I am likelyJose Ramón Becerra To invite everyone over for a carne asada.Brian Bienkowski You sound like an extrovert. I would be by myself reading a book. So one of my all time favorite movies isJose Ramón Becerra Friday.Brian Bienkowski Oh, man, me too.Jose Ramón Becerra Oh, I really, really love that movieBrian Bienkowski very much. So when I was yes, that was a that was a must watch, I would say between the ages of like, oh god, 16 to 25. I'd watch it a few times a year every year. Chris Tucker's is so fantastic in it. Well, thank you so much again, Jose, this has been a whole lot of fun. And before we get you out of here, what is the last book you read for fun? And you don't have to confine yourself to one word or a phrase here.Jose Ramón Becerra Yeah. All right. So I have like the nerdy answer to that, because I'm truly passionate about my research in my hometown. So there's a professor there named Dr. Juan de Lada, who wrote a book inland shift. And he's also like a hometown scholar that writes about the Inland Empire. So I really love that book. But something that I've read, that's just fun and not connected to my research, because I really don't read that much outside of, like, for research purposes, would probably be back in the day elementary school like Captain Underpants I really loved like the flip action. So surely that was like the last fun fun book I read, like just for fun.Brian Bienkowski Well, Jose, thank you so much. You're doing such incredible work. I'm so glad you're part of this cohort and have a great rest of your day.Jose Ramón Becerra Thank you so much.Brian Bienkowski All right. That's a wrap for this week, folks.

Transcript 


Brian Bienkowski

Jose, how are you doing this morning?

Jose Ramón Becerra

I'm doing pretty good. How are you?

Brian Bienkowski

I'm doing great. And where are you this morning?

Jose Ramón Becerra

I am in West Lafayette, Indiana.

Brian Bienkowski

All right, West Lafayette, Indiana. Far away from California's inland empire where you're originally from. So I want to talk to you a little bit about the Inland Empire region. So can you tell us about this place, and perhaps how you see it may have shaped your interest in environmental justice and your research?

Jose Ramón Becerra

Yeah, sure. So I was born and raised in the Inland Empire. So the Inland Empire is a region in southern California. It's around 50 miles 50 miles east of Los Angeles. Really, depending on who you ask, they might define the Inland Empire differently. So some folks will conceptualize it as the entirety of San Bernardino and Riverside counties. But for me, and a lot of people in my community, we think about it as the Valley portion that's surrounded by this mountain and stone geography. Some things that I love about the places that like, depending on the city that you're at, you're probably like 10 to 15 minutes away from like a nice hike when you go up to the mountains. And you're also –depending on the traffic– only, like 40 minutes to an hour and a half away from the nearest beach. It's a primarily Latino community, who live and work there each day. So there's a lot of great food all the time. I think it's a vibrant community, I love it. And how it shapes my interest in environmental justice and research, while my whole dissertation project is kind of dedicated to looking at air pollution exposure in the in the Inland Empire region. So I would say that it shapes my projects completely. From my research questions to my field site, to the people who I work with. I don't think this came around until I was in college, though. So because I guess growing up the signs of pollution that I see now, like the diesel trucks driving by or the wildfire smoke and stuff like that was just kind of part of the ordinary environment. So it wasn't until I started going to college and learning that like, not everybody in your community should have or like, asthma rates shouldn't be that high for everyone. So that's not it wasn't until I actually got into college I started learning about the issues that I'll see on a day-to-day basis as environmental and justices.

Brian Bienkowski

Was it a culture shock moving to Indiana?

Jose Ramón Becerra

Yeah, it was 100% Was it was the first time I was out of the area. So I was like I said, born and raised there. The only other places I really frequency, the war Los Angeles area to visit family and friends or my parents hometown in Tepatitlán, Jalisco, in Mexico. So I was just back and forth in these places all the time. And outside of that, yeah, I just hadn't been outside of like a few days. Maybe I hadn't been outside of California too much. California or Mexico.

Brian Bienkowski

So before we get And into some of the research you've been doing about the Inland Empire and where you're at now, what is the moment or event that helped shape your identity up to this point?

Jose Ramón Becerra

You know, funny enough, it was actually coming to Indiana for my PhD, or for my graduate studies for my Masters, and now my PhD. So like I said, I was in the Inland Empire for so long. The only other places I really frequented were Mexico. And so I was really just kind of in the middle of like my culture every day. So whether that's like Mexican culture, or Chicano culture, or just Southern California, Inland Empire culture, I was just immersed in it 24/7. And it was kind of like what they say like, culture is kind of like water for a fish. So it wasn't until I stepped out of there started living out here that I started missing so many things about like, what I see as my identity now, which is like the music, how people dress, how they talk, just the... you know, how people engage, the language and stuff like that. So yeah, oddly enough, it wasn't until I came out here to Indiana that I started really reflecting on who I was and how I was connected to my communities and stuff like that. So yeah, I think that that moment, just living out here has really solidified who I am.

Brian Bienkowski

I think travel is good for that people always talk about travel in terms of introducing you to other cultures, which is obviously I think, a net good, it's a good thing. But I can say when my wife and I we live in the Upper Peninsula, Michigan, and we are very, we are very Northern Great Lakes people. And when we were in New York City for a week, which I love, you know, it's just such a vibrant place, so fun to visit. And oh my gosh, did we feel like fish out of water, though! you know, we move very slow, we talk very slow, we're in people's way. So you know, I do think there is something to be exposed to other cultures, but also it kind of reaffirms who you are, and your own culture, as you mentioned. So I want to talk about your PhD work. But while you've been doing that, during the PhD work, you've also worked as a fellow in nonprofits, including Elevate in Chicago and for the EPA, the federal agency. So what did these experiences teach you about the value of kind of qualitative versus quantitative data? And do you have any examples?

Jose Ramón Becerra

Yeah, so I've been lucky enough to work with, and not just with them, I've been lucky enough to work with government, with nonprofits, with environmental justice organizations, and activists, and also just community members in different research sites. And I think the first thing I want to highlight is that there are individuals from all these different places who are doing such meaningful work. They're all dedicated to making environmental justice action happen, and essentially to alleviate disproportionate exposure to pollution. And so while this is happening, something that I kind of saw when I started reflecting on my ethnographic notes, so when I was collecting data for my own dissertation study, while talking to all these people and working with them through fellowships, was that just the underlying fact that quantitative data holds more value in policy arenas than qualitative data. And oftentimes, this is for good reason. So if an agency is going to ban a chemical, for example, they have to show that there's a causal relationship between like that chemical exposure and the health detriment. But at the same time, like an example of this can be like a community that gets together to push against a factory that's emitting whatever type of pollution. Their experiences and the qualitative data they come up with –and even if they organize–, is not going to make environmental change. Oftentimes, what happens is that this causes attention to whatever issues going on, it pulls in scientists and other people to do research and to do those quantitative studies to then make change. But unfortunately, what's happening is that while this science is getting done, or this quantitative data collection is getting done, and analysis and reports are getting written, it's a really slow movement, science is slow in many of those situations, and all the while people are being exposed to that same pollution. So there's no protections that are being offered, even when they present that qualitative information to whoever triggers like these other responses.

Brian Bienkowski

And so I don't want to put words in your mouth, but this qualitative data that mean these can be things like surveys, personal experiences, and in some cases, you know, in my profession, it's not it's not science, but in journalism, I mean, we look at storytelling and telling these people stories and narratives and communities as kind of a form of qualitative data. And and I think you can, you can tell that that can be really powerful, but as you said, the turns of the regulatory environment and science can move slowly sometimes. Jose, I should have set the stage before that question for you. listeners, what exactly you mentioned air pollution and kind of this data collection. Can you tell us what kind of science and research you're doing?

Jose Ramón Becerra

Yeah, so I do a lot of anthropology. So I'm in nog refer that means that I, like immerse myself in a community and collect a lot of qualitative data. So I do things like, participant observation. So I do observations and take notes on that. I do a lot of interviews with people. And at the same time, I'm doing community science, where I'm using portable pollution monitors to collect data with people who are from the Inland Empire. So I'm investigating through the frameworks of like political ecology, which is the idea that we're looking at the social-political dimensions of environmental change throughout time. So is like capitalism driving this change? What are the policies driving this change in? How does an environment become toxic, and I'm also really interested in who's exposed to pollution. So that's the environmental justice dimension of it that I include into my research.

Brian Bienkowski

So I want to talk more about the environmental concerns in the Inland Empire region. I think most of us when we hear warehouses, we don't associate them with pollution, we think of a big Amazon warehouse or something. But can you explain why this dense network of warehouses that exists there in the Inland Empire, what it looks like and what the environmental concerns and impacts are?

Jose Ramón Becerra

Yeah, so it's really interesting, you bring that up, because... so growing up, I'm from a city, Ontario, California, that's within the Inland Empire. And we have some of the highest warehouse density there. But I never really connected how they were, like sources of pollution. In my head, I was like, "Well, are they producing something in there that's, you know, driving up, like pollution in the region or whatnot?" But so if you look at the larger region, we have over 1 billion square feet of warehouses there. And like I said, we're in close proximity to Los Angeles. So what happens is that each day, we get ships full of containers that have goods inside of them, those containers get hauled eastward into the Inland Empire, it's estimated that 40% of all goods that come into the nation go through the Inland Empire, then the warehouses are locations where workers unload the containers, then later, repackage them and send them out to the rest of the nation, surrounding communities, via rail yard, diesel truck, and airplanes. And all of this transportation just increases massive amounts of pollution in the region that's been trapped by that mountainous dome geography I talked about a little bit earlier.

Brian Bienkowski

Can you talk about that geography and why it's problematic and how it traps pollutants?

Jose Ramón Becerra

Yeah, so if you look at a map for San Bernardino and Riverside County, you'll see that it's like this, this mountain that's connecting... this mountain range that connects the Los Angeles area to the Inland Empire. But then there's like this other barrier, kind of east and south of it, so all that, like mountainous dome geography traps pollution there, that comes from Los Angeles, that comes from the warehouse industry. And at the same time, we have with climate change a lot of more wildfires that burn more intensely and more frequent in the region. So even the wildfire smoke accumulates in that same space.

Brian Bienkowski

So otherwise, the air pollutants would be able to kind of push on into the atmosphere, but here they're getting trapped and kind of hovering above the community, right. So in this battle of residence against developers that I've talked to you about separately, and I know you're thinking and writing about these things, in that region, you say developers are often using outdated evidence and stationary monitor data. So what is your research shown about the monitoring data used and why it can be misleading?

Jose Ramón Becerra

Yeah, so the whole idea about outdated evidence came from when I was seeing participant observation. So I was following this, this applicant who was trying to build another warehouse in the Bloomington area, which is an unincorporated area in the Inland Empire. And when they were applying to do this, there was moments for the public to gather and kind of have their own comments about the warehouse, and if they wanted, they want to invite it in or not. And so the community was really great at organizing environmental justice organizations gathered the community, there's a lot of folks who are concerned individually. So a lot of folks were going up and giving their testimonials and they were like really talking about how air pollution had been damaging their health or the health of their children, for example, or even talking about like the cancer rates in the area. And in one of those testimonials, one of the one of the people who were, one of the persons talking kind of hinted at the fact that the environmental impact report was misleading. So it was through this person's own analysis and like reading the document that they were identifying that the data that they were using was outdated. And this got me really thinking about things like data sources, and scientific instrumentation, and even analysis. So depending on, like, how you're making your analysis, where the data is coming from, there could be a lot of things that are misleading when we're thinking about personal exposure. And so another thing that I'm really looking at is the differences between, or the limitations, at least, of stationary monitor data. So in places like the Inland Empire, especially where the environment is quickly changing, so we have warehouses that are built within months sometimes. And so the macro geography is constantly changing, people aren't just fixed in one location at all times. So as you know, like throughout our day, depending on our job, depending on what our daily activities look like, we're inside of houses, outdoors, in apartments, in your job side, on the street, driving through traffic, and all these different things are going to expose you to different levels of pollution. So just thinking about how there's these spatial temporal elements of people's activity is important how micro geography –so like the built environment, and how it's changing– also impacts different levels of exposure in the same region.

Brian Bienkowski

So I live in Sault Sainte Marie Michigan, and across the river is Sault Sainte Marie, Canada, same same name, different city, and there's a massive steel plant, and they all have their air monitoring at one time was placed, northwest of the building, and we live by Lake Superior. So the winds are always coming from the Northwest. And maybe I have this backwards. Basically, they had these monitors in a place where it was never capturing what was actually the air, you know, the wind was coming from the other direction. And so these stationary monitors were just completely they were really useless for a long time. And that's what the federal government relied on, it was industry data. So in your case, how do you how do you account for these micro geographies? Are you working with citizens or residents to try to do some monitoring that you feel is better and more accurate of what's actually happening?

Jose Ramón Becerra

So one of the projects that I'm doing, and I'm going to be doing from August to December this year, is working with community scientists to carry portable pollution monitors that are GPS-enabled. And this is a collaboration with Dr. Uman Park at University of Connecticut, that and so the project basically is going to be trying to account for how people navigate space. And while they carry these monitors, I'm gonna be able to tell how much pollution they're exposed to, throughout their daily activities, I'm also going to be in the community working with them to train them how to take behavioral notes, and this is going to be done through Qualtrics. So it's a widget that I'm gonna download into their phone, if they want to take notes on their cell phone, or if they want to use a voice recorder, they have that option. And then we're also taking demographic surveys. So that way we can make an analysis when we have enough data to show how social demographics might influence things like access to different types of jobs, and those jobs put you at different levels of exposure compared to you know, whatever, like just depending on the job, you might be exposed to different levels of exposure. So we're going to be really thinking critically about how access to job and just access to and wasted navigate space are kind of shaped by social demographics that are like embedded in deeper roots of like racial capitalism in the region.

Brian Bienkowski

How do you see these efforts as democratizing science in the region?

Jose Ramón Becerra

Yeah, so, um, I think that I see this effort is democratizing science, and that the first thing is that it's giving something that's legible for these policy arenas. When people talk about their experiences, like we should value them, that qualitative information should be valued. But for now, I think that it's important to still equip people with the scientific instrumentation in order to make their claims legible. So I think that I'm trying to join that qualitative aspect with the more quantitative and spatial data so that way, when it comes to people advocating for themselves, they have the data that's seen in these policy arenas. And at the same time, something that I see happen when people are advocating for themselves through testimonials is that they're up against people who are considered experts for the quantitative data. And by letting them collect data, it's kind of making them the experts. So they're learning why they're collecting data, how the monitors work, what kind of data they're collecting. So in their own way, they're becoming experts, not just of their own experiences, but also of the data collection process. And so in these two ways, I think that it's it's an effort to democratize science in the community.

Brian Bienkowski

I really liked that idea that they're already experts have their own experience. And this is making them experts in the data collection. That's a really cool way of thinking about it. I like that. Are you getting pushback in the region at all? Or is there pushback with this kind of economic versus or environmental thing? I have to imagine a good number of the residents work in many of these warehouses and provide for their families. So what's that kind of balancing act been like?

Jose Ramón Becerra

Yeah, I definitely see this, even in the Commission hearings I mentioned earlier, where there is a lot of people from the community who are trying to push against the warehouse, industry and just development in general. But then there's other people who are like in construction, who might be employed to build these warehouses that are kind of advocating for those jobs, because they're going to be local. They don't have to drive up like to Northern California, for example, to you know, do their job, tey could be next to their family. So there is pushback in that sense. But I think, in general, what I've seen is that people are really concerned with the type of jobs that these warehouses even provide. So what happens in the region is that many of the jobs available there are through agencies. So if you want a job there, you could start by going to an agency, and then the agency, like, recommends you to a warehouse and you start working there, but you're not actually hired through the company. So not being hired to the company has its own consequences, like there's limited liability they're accountable for, sometimes they don't have to provide health insurance and things like that, and you get lower pay. So when it comes to actual warehouse workers, I think that they know that these warehouses aren't necessarily like the like, what they want for their own future for their children's future. So I think that there's also a lot of people who are advocating for like, a different type of industry to, you know, come into the area.

Brian Bienkowski

I know personally, what I've written about the steel plant I mentioned earlier, you know, I have family who knows workers there and stuff around here. And the idea is not that we are, or I should I should speak for myself, you know, that we're not blaming the workers here. You know, the workers deserve protection, they deserve knowledge, they deserve data. And a lot of times, it's the people who have power and money and who are running these plants or warehouses or, you know, fleets of trucks that have the opportunity to reduce pollution, and they're not doing it because of various reasons. So I always try to make that clear that this isn't, we're not attacking the workers, you know, that it's definitely not their fault that, you know, this is this is goes higher than that to the regulatory, and kind of corporate level of a lot of these organizations. So what what tips would you have for other researchers that want to center communities like this in their own work?

Jose Ramón Becerra

Yeah, so I think that, um, it's super important to be in communication with the community, and ask them like what they need, even if that comes at the expense of modifying your research project or question, I think that if you want to center the community, the kind of data collection you do the type of analysis and all that should have them involved in they should have a say in like the kind of research you do, especially if you're going into this community fresh. And another thing, if you're doing environmental-justice-based research is to reach out to the local organizations, they are likely already doing a lot of wonderful work. They're connected to the community, they're also connected to policymakers and lawyers, and all that kind of stuff. So starting with them and talking to them having conversations and trying to be as transparent as possible can, in my opinion, take you a very long way in centering communities in your research.

Brian Bienkowski

I assume you still have family in the region. What's their reaction been to your to your research and your work? Have you have you taught them some things that they maybe didn't know before about where where they're from?

Jose Ramón Becerra

You know, they I think so. But I think they definitely teach me just as much and that's something I keep learning that like, when I come back home with the instruments, my family, my friends are super excited about it. And they helped me like even theorize for example, sometimes I'm writing a paper and I call them about like an interview we did or or like what their opinion is about, like, the relationship between something really like abstract like capitalism and pollution exposure. And they're super good at like teaching me what their perspective is. And a lot of the times it helps me even like formulate a paper on working on or, or write a piece of it and stuff like that. So I think that if anything there, they just keep teaching me and teaching me more and more stuff.

Brian Bienkowski

So you mentioned some of you know, some citizen science projects that you have upcoming here in a couple months. You know, maybe it's that or beyond that, what would you like to see change about the air pollution research field kind of broadly? And how do you see yourself as part of that change?

Jose Ramón Becerra

I think that something I would love to see is more community-based work. I think that, um, like, if we go on Google Scholar, for example, and we search up air pollution, we're gonna see 1000s of studies proving that air pollution is bad for health. And similarly, we'll see 1000s of studies showing that pollution is like, disproportionately distributed across national and global scales. So we know that these things are bad. And I think something important to look at would be community engagement, and also finding ways to merge and bring value to qualitative data and quantitative data together. I think that's what I would love to see. And I think that's what I'm trying to do with the projects that I'm engaged with as someone who's doing both very qualitative and quantitative data collection in my study. So I think that's that's my role in what I would love to see more more community based work.

Brian Bienkowski

What are you optimistic about?

Jose Ramón Becerra

I am very optimistic about a lot of the work that environmental justice organizations are already doing. Like in my hometown, or in the Inland Empire. There's people's collective for environmental justice, who are like excellent researchers, policy analyst and advocates for the community. And what I really love to see is that a lot of the folks who I've talked to, and the work that they're doing comes from, like, they're like they come from their hometown. So they're really invested in the type of work that they do. So I'm, I'm really optimistic about that. And it's inspiring to me. And I hope that future generations are able to see all this kind of work that's happening locally, and like in other communities, too. And you know, just find that inspiration and keep pushing forward for whatever cause that they're passionate about.

Brian Bienkowski

Well, Jose, this has been so so wonderful, I really love hearing about people's hometown, especially when they're very far from where I'm from. And when we were in person, I got to talk to you a little bit about where you're from as well. And it's just really great to hear about the research you're doing. So now I have a few fun questions before we get you out of here. You can just answer these these next three with just one word or short phrase. My first concert was

Jose Ramón Becerra

Wu Tang Clan.

Brian Bienkowski

Oh my god!

Jose Ramón Becerra

yeah, I, I think I also I had gone to other ones for my parents, I think and then like backyard concerts and stuff like that. But the first one like I paid for, and I was really excited about was Wu Tang.

Brian Bienkowski

Oh, my, oh, my goodness. So another peek behind the curtain. Jose and I talked hip hop a little bit when we were meeting in person. So Wu Tang, being your first concert is is quite something that's very cool. If I have a whole day off, I am likely

Jose Ramón Becerra

To invite everyone over for a carne asada.

Brian Bienkowski

You sound like an extrovert. I would be by myself reading a book. So one of my all time favorite movies is

Jose Ramón Becerra

Friday.

Brian Bienkowski

Oh, man, me too.

Jose Ramón Becerra

Oh, I really, really love that movie

Brian Bienkowski

very much. So when I was yes, that was a that was a must watch, I would say between the ages of like, oh god, 16 to 25. I'd watch it a few times a year every year. Chris Tucker's is so fantastic in it. Well, thank you so much again, Jose, this has been a whole lot of fun. And before we get you out of here, what is the last book you read for fun? And you don't have to confine yourself to one word or a phrase here.

Jose Ramón Becerra

Yeah. All right. So I have like the nerdy answer to that, because I'm truly passionate about my research in my hometown. So there's a professor there named Dr. Juan de Lada, who wrote a book inland shift. And he's also like a hometown scholar that writes about the Inland Empire. So I really love that book. But something that I've read, that's just fun and not connected to my research, because I really don't read that much outside of, like, for research purposes, would probably be back in the day elementary school like Captain Underpants I really loved like the flip action. So surely that was like the last fun fun book I read, like just for fun.

Brian Bienkowski

Well, Jose, thank you so much. You're doing such incredible work. I'm so glad you're part of this cohort and have a great rest of your day.

Jose Ramón Becerra

Thank you so much.

Brian Bienkowski

All right. That's a wrap for this week, folks. I hope you enjoyed my conversation with Jose I think I need to dust off the old Friday DVD this weekend and give it a watch.

The Sun’s Poles Hold the Key to Its Three Greatest Mysteries

The Sun’s poles may hold answers to long-standing mysteries about magnetic cycles, solar wind, and space weather. The polar regions of the Sun remain one of the least explored areas in solar science. Although satellites and ground-based observatories have captured remarkable details of the Sun’s surface, atmosphere, and magnetic field, nearly all of these views [...]

The Sun’s polar regions, long hidden from our Earth-bound perspective, are a critical frontier in solar physics, holding the secrets to the solar magnetic cycle and the origin of the fast solar wind. An upcoming mission is designed to achieve an unprecedented polar orbit, promising to finally reveal these uncharted territories and transform our ability to predict space weather.

Ltd.The Sun’s poles may hold answers to long-standing mysteries about magnetic cycles, solar wind, and space weather. The polar regions of the Sun remain one of the least explored areas in solar science. Although satellites and ground-based observatories have captured remarkable details of the Sun’s surface, atmosphere, and magnetic field, nearly all of these views come from the ecliptic plane, the narrow orbital path followed by Earth and most other planets. This restricted perspective means scientists have only limited knowledge of what occurs near the solar poles. Yet these regions are critical. Their magnetic fields and dynamic activity are central to the solar magnetic cycle and provide both mass and energy to the fast solar wind. These processes ultimately shape solar behavior and influence space weather that can reach Earth. Why the Poles Matter On the surface, the poles may seem calm compared to the Sun’s more active mid-latitudes (around ±35°), where sunspots, solar flares, and coronal mass ejections (CMEs) are common. However, research shows that polar magnetic fields contribute directly to the global solar dynamo and may act as the foundation for the next solar cycle by helping establish the Sun’s dipole magnetic field. Observations from the Ulysses mission further revealed that the fast solar wind originates mainly from vast coronal holes in the polar regions. For this reason, gaining a clearer view of the Sun’s poles is essential to addressing three of the most fundamental questions in solar physics: 1) How does the solar dynamo work and drive the solar magnetic cycle? The solar magnetic cycle refers to the periodic variation in sunspot number on the solar surface, typically on a time scale of approximately 11 years. During each cycle, the Sun’s magnetic poles undergo a reversal, with the magnetic polarities of the north and south poles switching. The Sun’s global magnetic fields are generated through a dynamo process. Key to this process are the differential rotation of the Sun that generates the active regions, and the meridional circulation that transport magnetic flux toward the poles. Yet, decades of helioseismic investigations have revealed conflicting results about the flow patterns deep within the convection zone. Some studies even suggest poleward flows at the base of the convection zone, challenging the classical dynamo models. High-latitude observations of the magnetic fields and plasma motions could provide the missing evidence to refine or rethink these models. 2) What drives the fast solar wind? The fast solar wind – a supersonic stream of charged particles – originates primarily from the polar coronal holes, and permeates the majority of the heliospheric volume, dominating the physical environment of interplanetary space. However, critical details regarding the origin of this wind remain unresolved. Does the wind originate from dense plumes within coronal holes or from the less dense regions between them? Are wave-driven processes, magnetic reconnection, or some combination of both responsible for accelerating the plasma in the wind? Direct polar imaging and in-situ measurements are required to settle the debate. 3) How do space weather events propagate through the solar system? Heliospheric space weather refers to the disturbances in the heliospheric environment caused by the solar wind and solar eruptive activities. Extreme space weather events, such as large solar flares and CMEs, can significantly trigger space environmental disturbances such as severe geomagnetic and ionospheric storms, as well as spectacular aurora phenomena, posing a serious threat to the safety of high-tech activities of human beings. To accurately predict these events, scientists must track how magnetic structures and plasma flows evolve globally, not just from the limited ecliptic view. Observations from a vantage point out of the ecliptic would provide an overlook of the CME propagation in the ecliptic plane. Past Efforts Scientists have long recognized the importance of solar polar observations. The Ulysses mission, launched in 1990, was the first spacecraft to leave the ecliptic plane and sample the solar wind over the poles. Its in-situ instruments confirmed key properties of the fast solar wind but lacked imaging capability. More recently, the European Space Agency’s Solar Orbiter has been gradually moving out of the ecliptic plane and is expected to reach latitudes of around 34° in a few years. While this represents a remarkable progress, it still falls far short of the vantage needed for a true polar view. A number of ambitious mission concepts have been proposed over the past decades, including the Solar Polar Imager (SPI), the POLAR Investigation of the Sun (POLARIS), the Solar Polar ORbit Telescope (SPORT), the Solaris mission, and the High Inclination Solar Mission (HISM). Some envisioned using advanced propulsion, such as solar sails, to reach high inclinations. Others relied on gravity assists to incrementally tilt their orbits. Each of these missions would carry both remote-sensing and in-situ instruments to image the Sun’s poles and measure key physical parameters above the poles. The SPO Mission The Solar Polar-orbit Observatory (SPO) is designed specifically to overcome the limitations of past and current missions. Scheduled for launch in January 2029, SPO will use a Jupiter gravity assist (JGA) to bend its trajectory out of the ecliptic plane. After several Earth flybys and a carefully planned encounter with Jupiter, the spacecraft will settle into a 1.5-year orbit with a perihelion of about 1 AU and an inclination of up to 75°. In its extended mission, SPO could climb to 80°, offering the most direct view of the poles ever achieved. The 15-year lifetime of the mission (including an 8-year extended mission period) will allow it to cover both solar minimum and maximum, including the crucial period around 2035 when the next solar maximum and expected polar magnetic field reversal will occur. During the whole lifetime, SPO will repeatedly pass over both poles, with extended high-latitude observation windows lasting more than 1000 days. The SPO mission aims at breakthroughs on the three scientific questions mentioned above. To meet its ambitious objectives, SPO will carry a suite of several remote-sensing and in-situ instruments. Together, they will provide a comprehensive view of the Sun’s poles. The remote-sensing instruments include the Magnetic and Helioseismic Imager (MHI) to measure magnetic fields and plasma flows at the surface, the Extreme Ultraviolet Telescope (EUT) and the X-ray Imaging Telescope (XIT) to capture dynamic events in the solar upper atmosphere, the VISible-light CORonagraph (VISCOR) and the Very Large Angle CORonagraph (VLACOR) to track the solar corona and solar wind streams out to 45 solar radii (at 1 AU). The in-situ package includes a magnetometer and particle detectors to sample the solar wind and interplanetary magnetic field directly. By combining these observations, SPO will not only capture images of the poles for the first time but also connect them to the flows of plasma and magnetic energy that shape the heliosphere. SPO will not operate in isolation. It is expected to work in concert with a growing fleet of solar missions. These include the STEREO Mission, the Hinode satellite, the Solar Dynamics Observatory (SDO), the Interface Region Imaging Spectrograph (IRIS), the Advanced Space-based Solar Observatory (ASO-S), the Solar Orbiter, the Aditya-L1 mission, the PUNCH mission, as well as the upcoming L5 missions (e.g., ESA’s Vigil mission and China’s LAVSO mission). Together, these assets will form an unprecedented observational network. SPO’s polar vantage will provide the missing piece, enabling nearly global 4π coverage of the Sun for the first time in human history. Looking Ahead The Sun remains our closest star, yet in many ways it is still a mystery. With SPO, scientists are poised to unlock some of its deepest secrets. The solar polar regions, once hidden from view, will finally come into focus, reshaping our understanding of the star that sustains life on Earth. The implications of SPO extend far beyond academic curiosity. A deeper understanding of the solar dynamo could improve predictions of the solar cycle, which in turn affects space weather forecasts. Insights into the fast solar wind will enhance our ability to model the heliospheric environment, critical for spacecraft design and astronaut safety. Most importantly, better monitoring of space weather events could help protect modern technological infrastructure — from navigation and communications satellites to aviation and terrestrial power systems.

For the first time, scientists in the Femtosecond Spectroscopy Unit at the Okinawa Institute of Science and Technology (OIST) have directly tracked how dark excitons evolve in atomically thin materials. This achievement paves the way for advances in both classical and quantum information technologies. The study was published in Nature Communications. Professor Keshav Dani, who leads the unit, emphasized the importance of the work: “Dark excitons have great potential as information carriers, because they are inherently less likely to interact with light, and hence less prone to degradation of their quantum properties. However, this invisibility also makes them very challenging to study and manipulate. Building on a previous breakthrough at OIST in 2020, we have opened a route to the creation, observation, and manipulation of dark excitons.” “In the general field of electronics, one manipulates electron charge to process information,” explains Xing Zhu, co-first author and PhD student in the unit. “In the field of spintronics, we exploit the spin of electrons to carry information. Going further, in valleytronics, the crystal structure of unique materials enables us to encode information into distinct momentum states of the electrons, known as valleys.” The ability to use the valley dimension of dark excitons to carry information positions them as promising candidates for quantum technologies. Dark excitons are by nature more resistant to environmental factors like thermal background than the current generation of qubits, potentially requiring less extreme cooling and making them less prone to decoherence, where the unique quantum state breaks down. The experimental setup at OIST, featuring the world-leading TR-ARPES (time- and angle-resolved photoemission spectroscopy) microscope, which features a proprietary, tabletop XUV (extreme ultraviolet) source, capable of imaging the electrons and excitons at femtosecond timescales (1fs = one quadrillionth (10-15) of a second). Credit: Jeff Prine & Andrew Scott (OIST)Defining landscapes of energy with bright and dark excitons In the last ten years, researchers have made significant strides in studying a family of atomically thin semiconductors called TMDs (transition metal dichalcogenides). Like all semiconductors, TMDs consist of atoms arranged in a crystal lattice that restricts electrons to defined energy levels, or bands, such as the valence band. When light strikes the material, electrons are lifted from the valence band into the higher-energy conduction band, leaving behind positively charged vacancies known as holes. The mutual attraction between the negatively charged electrons and positively charged holes binds them into hydrogen-like quasiparticles called excitons. If the electron and hole share specific quantum features, such as having the same spin configuration and occupying the same “valley” in momentum space (the energy minima available in the crystal lattice), they recombine within a trillionth of a second (1ps = 10−12 second), releasing light. These are known as “bright” excitons. However, if the quantum properties of the electron and hole do not match up, the electron and hole are forbidden from recombining on their own and do not emit light. These are characterized as ‘dark’ excitons. “There are two ‘species’ of dark excitons,” explains Dr. David Bacon, co-first author who is now at University College London, “momentum-dark and spin-dark, depending on where the properties of electron and hole are in conflict. The mismatch in properties not only prevents immediate recombination, allowing them to exist up to several nanoseconds (1ns = 10−9 second – a much more useful timescale), but also makes dark excitons more isolated from environmental interactions.” The atomic structure of ultrathin semiconductors like TMDs is hexagonal, and this symmetry is reflected in momentum space, where the conduction (top) and valence (bottom) bands each have local energy minima and maxima at specific points (K), which can be visualized as valleys in a momentum landscape. Time-reversal symmetry in quantum mechanics dictates that what happens in one valley is mirrored in the opposite valley: if the conduction band at K has spin-down (red), then K’ must have spin-up (blue), leading to an alternating pattern along the edge of the hexagon. Bright excitons form when the electron rests in the same valley and has the same spin as the corresponding hole. By using either left- or right-circularly polarized light, one can selectively populate bright exciton in a specific valley.

Insert adapted from Zhu et al., (2025) Nature Communications 16 6385“The unique atomic symmetry of TMDs means that when exposed to a state of light with a circular polarization, one can selectively create bright excitons only in a specific valley. This is the fundamental principle of valleytronics. However, bright excitons rapidly turn into numerous dark excitons that can potentially preserve the valley information. Which species of dark excitons are involved and to what degree they can sustain the valley information is unclear, but this is a key step in the pursuit of valleytronic applications,” explains Dr. Vivek Pareek, co-first author and OIST graduate who is now a Presidential Postdoctoral Fellow at the California Institute of Technology. Observing electrons at the femtosecond scale With the state-of-the-art TR-ARPES (time- and angle-resolved photoemission spectroscopy) system at OIST, equipped with a custom-built table-top XUV (extreme ultraviolet) source, the researchers were able to monitor how different excitons evolved after bright excitons formed in a particular valley of a TMD semiconductor. They accomplished this by measuring momentum, spin state, and the population of electrons and holes at the same time, a combination of properties that had never previously been quantified together.

Credit: Jack Featherstone (OIST), adapted from Zhu et al. (2025) Nature Communications 16 6385Their findings show that within a picosecond, some bright excitons are scattered by phonons (quantized crystal lattice vibrations) into different momentum valleys, rendering them momentum-dark. Later, spin-dark excitons dominate, where electrons have flipped spin within the same valley, persisting on nanosecond scales. With this, the team has overcome the fundamental challenge of how to access and track dark excitons, laying the foundation for dark valleytronics as a field. Dr. Julien Madéo of the unit summarizes: “Thanks to the sophisticated TR-ARPES setup at OIST, we have directly accessed and mapped how and what dark excitons keep long-lived valley information.

A collaboration between African and American researchers and a community living in one of the most hostile landscapes of northern Kenya has uncovered key genetic adaptations that explain how pastoralist people have been able to thrive in the region.Underlying the population’s abilities to live in Turkana, a place defined by extreme heat, water scarcity and limited vegetation, has been hundreds of years of natural selection, according to a study published in Science.It shows how the activity of key human genes has changed over millennia and the findings place “Turkana and sub-Saharan Africa at the forefront of genomic research, a field where Indigenous populations have historically been underrepresented”, according to Charles Miano, one of the study’s co-authors and a postgraduate student at the Kenya Medical Research Institute (Kemri).The research sequenced 367 whole genomes and analysed more than 7m genetic variants, identifying several regions of the genome under natural selection. It was conducted through the Turkana Health and Genomics Project (THGP), an initiative bringing together researchers from Kenya and the US, including Kemri, the Turkana Basin Institute (TBI), Vanderbilt University in Tennessee and the University of California, Berkeley.The genomic analysis found eight regions of DNA that had undergone natural selection but one gene, STC1, expressed in the kidneys, showed exceptionally strong evidence of humans adapting to extreme environments. Evidence included the body’s response to dehydration and processing purine-rich foods such as meat and blood, staples of the Turkana people’s diet.Turkana women give water to their goats from a shallow well.

Photograph: Monicah Mwangi/ReutersTurkana stretches across a large swathe of northern Kenya, one of the most arid regions in the world, where shade is scarce and water even more rare. Rainfall arrives in short, unpredictable bursts, and securing enough water for themselves and their herds of cattle, goats and camels is a daily chore. Fetching water can involve journeys of many hours each day across hot terrain devoid of vegetation.About 70% to 80% of the community’s diet comes from animal sources, mostly milk, blood and meat, reflecting resourcefulness and adaptation to scarcity, which is common among pastoralist societies around the world living in environments where crops cannot grow and where markets are too far away to be accessed on foot.Yet, after years of documenting the Turkana people’s lifestyle and studying blood and urine samples to assess their health, researchers found that, although the community consumes too much purine, which should lead to gout, the condition rarely appears among the Turkana.“About 90% of the people assessed were dehydrated but generally healthy,” said Prof Julien Ayroles, from the University of California, Berkeley, one of the project’s co-principal investigators. “The Turkana have maintained their traditional way of life for thousands of years, providing us with an extraordinary window into human adaptation.”Genetic adaptations are believed to have emerged about 5,000 years ago, coinciding with the aridification of northern Africa, the study suggesting that as the region became drier, natural selection favoured variants that enhanced survival under arid conditions.A Turkana woman carries the leg of a cow as she migrates with Turkana people to find water and grazing land for cattle. Photograph: Goran Tomašević/Reuters“This research demonstrates how our ancestors adapted to dramatic climate shifts through genetic evolution,” said Dr Epem Esekon, responsible for Turkana county’s health and sanitation sector.However, as more members of the Turkana community move to towns and cities, the same adaptations that once protected them may now increase risks of chronic lifestyle diseases, a phenomenon known as “evolutionary mismatch”. This occurs when adaptations shaped by one environment become liabilities in another, highlighting how rapid lifestyle changes interact with deep evolutionary history.When the researchers compared biomarkers and gene expression – the process by which information encoded in a gene is turned into a function – in the genomes of city-dwelling Turkana people with their kin still living in the villages, they found an imbalance of gene expression that may predispose them to chronic diseases such as hypertension or obesity, which are more common in urban settings where diets, water availability and activity patterns are radically different.“Understanding these adaptations will guide health programmes for the Turkana, especially as some shift from traditional pastoralism to city life,” said Miano.As the world faces rapid environmental change, the Turkana people’s story offers inspiration and practical insights. For generations, the researchers said, this community has developed and maintained sophisticated strategies for surviving in a challenging and variable environment, knowledge that becomes increasingly valuable as the climate crisis creates new survival challenges.The study has combined genetic findings with community insights on environment, lifestyle and health. Photograph: Luis Tato/AFP/Getty ImagesFor close to a decade, the project centred on co-production of knowledge, combining genomic science with ecological and anthropological expertise. The agenda emerged from dialogue with Turkana elders, scientists, chiefs and community members, conversations about health, diet and change, often in the evening around a campfire.“Working with the Turkana has been transformative for this study,” said Dr Sospeter Ngoci Njeru, a co-principal investigator and deputy director at Kemri’s Centre for Community Driven Research. “Their insights into their environment, lifestyle and health have been essential to connecting our genetic findings to real-world biology and survival strategies.”Dr Dino Martins, director of the TBI, says the deep ecological connection and the adaptation to one of the Earth’s hottest and most arid environments provides lessons for how climate continues to shape human biology and health. “The discovery adds another important piece of knowledge to our wider understanding of human evolution,” he said.Researchers say other pastoralist communities in similar environments in east Africa, including the Rendille, Samburu, Borana, Merille, Karamojong and Toposa, are likely to share this adaptation.The research team will create a podcast in the Turkana language to share the study’s findings and also plan to offer the community practical health considerations that arise from rapidly changing lifestyles.

The study links this to the potential for seven senses, with applications in AI and neuroscience. Skoltech researchers have developed a mathematical model to study how memory works. Their analysis led to unexpected insights that may advance the design of robots, artificial intelligence, and our understanding of human memory. The study, published in Scientific Reports, suggests there could be an ideal number of senses. If that is true, then humans with five senses might actually benefit from having a few more. “Our conclusion is, of course, highly speculative in application to human senses, although you never know: It could be that humans of the future would evolve a sense of radiation or magnetic field. But in any case, our findings may be of practical importance for robotics and the theory of artificial intelligence,” said study co-author Professor Nikolay Brilliantov of Skoltech AI. “It appears that when each concept retained in memory is characterized in terms of seven features — as opposed to, say, five or eight — the number of distinct objects held in memory is maximized.” Modeling memory engrams Building on a framework established in the early 20th century, the team focused on the basic units of memory known as “engrams.” An engram can be described as a sparse network of neurons distributed across different brain regions that activate together. Its conceptual content is an idealized object defined by multiple characteristics. In human memory, these characteristics map to sensory inputs. For instance, the memory of a banana would include its image, smell, taste, and other sensory details. Altogether, this forms a five-dimensional representation that exists within a larger five-dimensional space containing all other stored concepts. The five senses. Credit: Modified by Nicolas Posunko/Skoltech from image generated by Deep Style (Abstract) model on Deep Dream GeneratorOver time, engrams can become more refined or more diffuse depending on how frequently they are triggered by external stimuli acting through the senses, which in turn recall the memory of the object. This process represents how learning strengthens memories while disuse leads to forgetting through environmental interaction. “We have mathematically demonstrated that the engrams in the conceptual space tend to evolve toward a steady state, which means that after some transient period, a ‘mature’ distribution of engrams emerges, which then persists in time,” Brilliantov commented. “As we consider the ultimate capacity of a conceptual space of a given number of dimensions, we somewhat surprisingly find that the number of distinct engrams stored in memory in the steady state is the greatest for a concept space of seven dimensions. Hence, the seven senses claim.” Maximizing conceptual space In other words, let the objects that exist out there in the world be described by a finite number of features corresponding to the dimensions of some conceptual space. Suppose that we want to maximize the capacity of the conceptual space expressed as the number of distinct concepts associated with these objects. The greater the capacity of the conceptual space, the deeper the overall understanding of the world. It turns out that the maximum is attained when the dimension of the conceptual space is seven. From this, the researchers conclude that seven is the optimal number of senses. According to the researchers, this number does not depend on the details of the model — the properties of the conceptual space and the stimuli providing the sense impressions. The number seven appears to be a robust and persistent feature of memory engrams as such. One caveat is that multiple engrams of differing sizes existing around a common center are deemed to represent similar concepts and are therefore treated as one when calculating memory capacity. The memory of humans and other living beings is an enigmatic phenomenon tied to the property of consciousness, among other things. Advancing the theoretical models of memory will be instrumental to gaining new insights into the human mind and recreating humanlike memory in AI agents.

Autism Research Is a Chance for RFK Jr. to Take Pesticides Seriously

Unlike some of his other concerns, these echo legitimate science.

Pesticides once appeared to be a clear target for Robert F. Kennedy Jr.’s desire to “make America healthy again.” Before becoming the health secretary, he described Monsanto, the maker of the glyphosate-based herbicide Roundup, as “enemy of every admirable American value,” and vowed to “ban the worst agricultural chemicals already banned in other countries.” Since he came to power, many of Kennedy’s fans have waited eagerly for him to do just that.Kennedy has yet to satisfy them: In the latest MAHA action plan on children’s health, released last week, pesticides appear only briefly on a laundry list of vague ideas. The plan says that the government should fund research on how farmers could use less of them, and that the government "will work to ensure that the public has awareness and confidence” in the EPA’s existing pesticide-review process, which it called “robust.”Unlike Kennedy’s concerns about vaccines, his concerns about pesticides have echoed those found in a body of legitimate research. Studies have found associations between exposure to some herbicides and pesticides and cancer, hormone disruption, and other acute and chronic health conditions. These include neurodevelopmental impacts in children, such as autism—which Kennedy has also promised to tackle.Right now his department’s promised report on what has caused rates of autism to rise over recent decades is expected to highlight Tylenol use, whether during pregnancy or, as my colleague Tom Bartlett reported, based on Kennedy’s correspondence with a fringe researcher, in early childhood. Researchers generally point to a change in diagnostic criteria as the primary reason rates have spiked so dramatically. They also consider autism a complex condition that does not appear to have a single cause: Studies suggest that genetics play a bigger role than environmental factors in determining a person’s risk, though both seem likely to contribute and may work in concert. A serious effort from the government to understand its causes would require investment in long-term, large-cohort, and detailed studies that might cast light on the contribution of many environmental factors, including pesticides. Several studies have found neurological impacts associated with pesticides. UC Davis’s MIND Institute put out a study in 2014 that found autism risk was much higher among children whose mothers had lived near agricultural-pesticide areas while pregnant. A 2017 paper found that zip codes that conducted aerial spraying for mosquitoes—a pesticide—had comparatively higher rates of autism than zip codes that didn’t. Others have linked pesticides to a range of behavioral and cognitive impairment in children.Rebecca Schmidt, a molecular epidemiologist and professor at UC Davis, has been researching potential risk factors for autism as part of the school’s long-term MARBLES study of mothers and children. Schmidt and her colleagues study families with at least one child already diagnosed with the condition—to see what environmental and biological factors may raise the risk of subsequent children being diagnosed. (Younger siblings of a child with autism have on average a 20 percent chance of also having it.) Her own research, she told me, has not seen as dramatic of results for pesticides as the 2014 paper—which she also worked on—reported, though other labs have found associations of their own between prenatal pesticide exposure and autism.These studies, like most studies that assess environmental exposures, typically cannot determine causality between agricultural-pesticide exposure and autism risk. Investigating links between pesticides and health outcomes is challenging; researchers can look at geographic proximity to sprayed fields, but drilling down to find out how much pesticide actually ended up in a person’s body requires herculean diagnostic efforts, such as frequent urine sampling. And the conclusions drawn from these studies can only point to associations between certain exposures and the likelihood of developing the condition: Showing direct causality would involve willingly exposing pregnant mothers and infants to pesticides and seeing what happens, which scientists cannot do, for obvious reasons. But based on what she knows now, Schmidt told me, “pesticides are probably not a good exposure for any pregnant person, or even children,” since their brains are still developing.In investigating autism causes, Kennedy could also consider another environmental factor: air pollution. Breathing air pollution does have robust evidence linking it to neurodevelopmental effects in children, including autism. The Trump administration’s policy changes since January have predominantly tipped the country toward more air pollution, not less, while its climate-policy rollbacks will contribute even further to the burden of air pollution from wildfires. Meanwhile, some evidence also suggests a link between flame-retardant exposure and behavioral-developmental problems in children. Other studies have found possible links between pre- and postnatal exposure to PFAS, or “forever chemicals,” and autism.All of this means that following the science would give Kennedy many places to look. “We've been working on this for over a decade,” Schmidt told me. “Every time we do a study, it raises new questions. And so it’s a complex picture that takes time to tease apart.” Designing and completing strong studies of any of these factors is challenging and costly. If the federal government did want to put its resources toward finding the causes of autism, Kennedy would do well to increase funding for large, national studies that follow people for years.The latest MAHA plan does say that the National Institutes of Health, along with other agencies, will develop a way to evaluate “cumulative exposure,” or the impact of the cocktail of chemicals Americans are regularly interacting with—including pesticides. It does not say how that research will be funded or which of the tens of thousands of in-use chemicals the agencies would focus on.Since taking office, Kennedy has mostly avoided even rhetorically linking specific environmental exposures to health concerns. An earlier MAHA report had more to say on pesticides, but The New York Times and Politico reported that Republican lawmakers as well as the farm lobby expressed concern about its potential impact on farmers. At a Senate hearing, Kennedy said that there are “a million farmers who rely on glyphosate” and told lawmakers that “we are not going to do anything to jeopardize that business model.” At a Heritage Foundation event last month, Kennedy’s senior adviser, Calley Means, said on a panel that corn and soybean farmers are not the “enemy,” but rather that the “deep state” is. (Corn and soy are two of the most heavily sprayed crops.) In response to a request for comment, HHS pointed me to last week’s MAHA plan, as well as the EPA’s work to evaluate environmental risks while phasing out animal testing.This shift has raised the ire of some of Kennedy’s most ardent fans. Zen Honeycutt, the founder of the advocacy group Moms Across America who has been a major Kennedy supporter, said shortly after the MAHA plan was unveiled last week that her vote for the Republican Party is not guaranteed: “We will be actively campaigning to get people into office coming in the midterms that will protect our children, and we are not beholden to political parties.” In a statement later that day, she said that eliminating specific mentions of glyphosate and atrazine, another widely used pesticide that appeared in the first report and has concerning health implications, is “a tactic to appease the pesticide companies.”Some of Kennedy’s defenders rightly point out that he is not in charge of the EPA, which regulates pesticides, or the U.S. Department of Agriculture, which oversees farming policies. Even if he cannot regulate pesticides himself, he is in charge of the National Institutes of Health, “and the NIH can study the causes of the effects of these chemicals on Americans. Those studies can drive the marketplace and policy change,” Vani Hari, a food activist, MAHA influencer, and vocal supporter of Kennedy, told me. (In particular, she wants to see the United States, as some other countries have, eliminate the practice of spraying glyphosate on crop fields right before harvest, which farmers do to dry out the crops.) Kennedy understands the threat these chemicals pose, she told me: “When there is an opportunity to add influence, he will. He’s not afraid to speak up.”I asked whether she would be disappointed if the forthcoming autism report doesn’t mention pesticides and instead focuses on Tylenol and folate deficiencies. She told me she doubted that the autism report would overlook pesticides. “I don’t see that even happening,” she said. Yet in his few months in office, Kennedy has had many chances to let science guide him and has let them pass—on the health benefits of seed oils, the safety of abortion pills, children’s mental-health screening, and, most notably, vaccine policy. This may be one more.
