Jane Goodall, legendary researcher and advocate for the planet, dies at 91

Jane Goodall, the conservationist renowned for her groundbreaking chimpanzee field research, has died.

Jane Goodall, the conservationist renowned for her groundbreaking chimpanzee field research and globe-spanning environmental advocacy, has died. She was 91.The Jane Goodall Institute said in post on Instagram Wednesday that the renowned primatologist has died.While living among chimpanzees in Africa decades ago, Goodall documented the animals using tools and doing other activities previously believed to be exclusive to people, and also noted their distinct personalities. Her observations and subsequent magazine and documentary appearances in the 1960s transformed how the world perceived not only humans’ closest living biological relatives but also the emotional and social complexity of all animals, while propelling her into the public consciousness.“Out there in nature by myself, when you’re alone, you can become part of nature and your humanity doesn’t get in the way,” she told The Associated Press in 2021. “It’s almost like an out-of-body experience when suddenly you hear different sounds and you smell different smells and you’re actually part of this amazing tapestry of life.”In her later years, Goodall devoted decades to education and advocacy on humanitarian causes and protecting the natural world. In her usual soft-spoken British accent, she was known for balancing the grim realities of the climate crisis with a sincere message of hope for the future.From her base in the coastal U.K. town of Bournemouth, she traveled nearly 300 days a year well into her 90’s to speak to packed auditoriums around the world. Between more serious messages, her speeches often featured her whooping like a chimpanzee or lamenting that Tarzan chose the wrong Jane.FILE - Jane Goodall plays with Bahati, a 3-year-old female chimpanzee, at the Sweetwaters Chimpanzee Sanctuary near Nanyuki, north of Nairobi, on Dec. 6, 1997.AP Photo/Jean-Marc Bouju, FileWhile first studying chimps in Tanzania in the early 1960s, Goodall was known for her unconventional approach. She didn’t simply observe them from afar but immersed herself in every aspect of their lives. She fed them and gave them names instead of numbers, something for which she received pushback from some scientists.Her findings were circulated to millions when she first appeared on the cover of National Geographic in 1963 and soon after in a popular documentary. A collection of photos of Goodall in the field helped her and even some of the chimps become famous. One iconic image showed her crouching across from the infant chimpanzee named Flint. Each has arms outstretched, reaching for the other.In 1972, the Sunday Times published an obituary for Flo, Flint’s mother and the dominant matriarch, after she was found face down on the edge of a stream. Flint died about three weeks later after showing signs of grief, eating little and losing weight.″What the chimps have taught me over the years is they’re so like us. They’ve blurred the line between humans and animals,″ she told The Associated Press in 1997.Goodall has earned top civilian honors from a number of countries including Britain, France, Japan and Tanzania. She was awarded the Presidential Medal of Freedom in 2025 by then-U.S. President Joe Biden and won the prestigious Templeton Prize in 2021.FILE - President Joe Biden, right, presents the Presidential Medal of Freedom, the Nation's highest civilian honor, to conservationist Jane Goodall in the East Room of the White House, Jan. 4, 2025, in Washington.AP Photo/Manuel Balce Ceneta, File“Her groundbreaking discoveries have changed humanity’s understanding of its role in an interconnected world, and her advocacy has pointed to a greater purpose for our species in caring for life on this planet,” said the citation for the Templeton Prize, which honors individuals whose life’s work embodies a fusion of science and spirituality.Goodall was also named a United Nations Messenger of Peace and published numerous books, including the bestselling autobiography “Reason for Hope.”Born in London in 1934, Goodall said her fascination with animals began around when she learned to crawl. In her book, “In the Shadow of Man,” she described an early memory of hiding in a henhouse to see a chicken lay an egg. She was in there so long her mother reported her missing to the police.She bought her first book — Edgar Rice Burroughs’ “Tarzan of the Apes” — when she was 10 and soon made up her mind about her future: Live with wild animals in Africa.That plan stayed with her through a secretarial course when she was 18 and two different jobs. And by 1957, she accepted an invitation to travel to a farm in Kenya owned by a friend’s parents.It was there that she met the famed anthropologist and paleontologist Louis Leakey at a natural history museum in Nairobi, and he gave her a job as an assistant secretary.Three years later, despite Goodall not having a college degree, Leakey asked if she would be interested in studying chimpanzees in what is now Tanzania. She told the AP in 1997 that he chose her “because he wanted an open mind.”The beginning was filled with complications. British authorities insisted she have a companion, so she brought her mother at first. The chimps fled if she got within 500 yards of them. She also spent weeks sick from what she believes was malaria, without any drugs to combat it.But she was eventually able to gain the animals’ trust. By the fall of 1960 she observed the chimpanzee named David Greybeard make a tool from twigs and use it to fish termites from a nest. It was previously believed that only humans made and used tools.She also found that chimps have individual personalities and share humans’ emotions of pleasure, joy, sadness and fear. She documented bonds between mothers and infants, sibling rivalry and male dominance. In other words, she found that there was no sharp line between humans and the animal kingdom.In later years, she discovered chimpanzees engage in a type of warfare, and in 1987 she and her staff observed a chimp “adopt” a 3-year-old orphan that wasn’t closely related.Goodall received dozens of grants from the National Geographic Society during her field research tenure, starting in 1961.In 1966, she earned a Ph.D. in ethology — becoming one of the few people admitted to University of Cambridge as a Ph.D. candidate without a college degree.Her work moved into more global advocacy after she watched a disturbing film of experiments on laboratory animals at a conference in 1986.″I knew I had to do something,″ she told the AP in 1997. ″It was payback time.″When the COVID-19 pandemic hit in 2020 and halted her in-person events, she began podcasting from her childhood home in England. Through dozens of “Jane Goodall Hopecast” episodes, she broadcast her discussions with guests including U.S. Sen. Cory Booker, author Margaret Atwood and marine biologist Ayana Elizabeth Johnson.“If one wants to reach people; If one wants to change attitudes, you have to reach the heart,” she said during her first episode. ”You can reach the heart by telling stories, not by arguing with people’s intellects.”In later years, she pushed back on more aggressive tactics by climate activists, saying they could backfire, and criticized “gloom and doom” messaging for causing young people to lose hope.In the lead-up to 2024 elections, she co-founded “Vote for Nature,” an initiative encouraging people to pick candidates committed to protecting the natural world.She also built a strong social media presence, posting to millions of followers about the need to end factory farming or offering tips on avoiding being paralyzed by the climate crisis.Her advice: “Focus on the present and make choices today whose impact will build over time.”--By Hallie Golden/The Associated PressIf you purchase a product or register for an account through a link on our site, we may receive compensation.

Nearly 90 percent of EPA furloughed as government shuts down

About 89 percent of the Environmental Protection Agency’s (EPA’s) workforce is being furloughed as the government shuts down, according to contingency plans that were posted online this week.

About 89 percent of the Environmental Protection Agency’s (EPA’s) workforce is being furloughed as the government shuts down, according to contingency plans that were posted online this week. According to the plan, just 1,734 of the EPA’s 15,166 employees are slated to continue working during the shutdown, which began Wednesday. The plan also gives a window into the degree of staffing losses at the EPA in recent months, as the agency had 17,080 employees at the start of the year.  During the furlough period, the agency will no longer carry out most civil inspections related to potential violations of environmental law.  It will also no longer conduct most of its research or issue new permits or grants. Some hazardous waste cleanup will be halted if there is no imminent threat to human health and property. The EPA will still continue emergency and disaster assistance, hazardous waste cleanup where there is an “imminent threat to human life" and criminal investigations. The Trump administration’s plan is similar to the most recent contingency plan issued by the Biden administration in September 2024. Under that plan, 1,734 employees out of 16,851 would have been expected to continue working. Under the Biden-era plan, civil inspections, issuance of new grants and permits, research and some hazardous waste cleanup also would have ceased. Marc Boom, a former EPA senior policy adviser during the Biden administration, said during a press call ahead of the shutdown that if one occurs “nobody will be holding polluters accountable for what they dump into the air we breathe and the water that we drink.” But Boom also said the Trump administration is making the problem worse. “Over the past 9 months, the White House and EPA leadership have already been shutting down the agency from within,” he said. “They've clawed back hundreds of community grants, rolled back protections against forever chemicals and pesticides, relaxed enforcement for polluters … and they've shuttered key programs like the Environmental Justice Office, the Office of Atmospheric Protection and now, they're closing down EPA's scientific backbone, the Office of Research and Development.” The EPA has said that its actions are in support of a deregulatory agenda that seeks to boost the U.S. economy.

We're precipitating an extermination rather than an extinction event'

Broadcaster and campaigner Chris Packham is on a mission to cut overconsumption, take on fossil fuel giants and create a fairer world

Wildlife broadcaster Chris Packham’s kinship with the natural world began before he could even speak. As a young child in his parents’ small back garden in Southampton, UK, he became fascinated with tadpoles, snails and ladybirds. Soon his bedroom filled up with jam jars and tanks, and then the garden was crammed with enclosures. His obsessive interests expanded from moths and newts to include foxes and kestrels. Packham puts this intense curiosity down in part to being autistic. He says this shaped his keen ability to focus and find patterns – and his need to shelter from overwhelming social interactions. On and off screen, Packham isn’t afraid to speak his mind. He is a vocal supporter of environmental issues and animal rights, with campaigns aiming to put an end to game shooting and industrial farming. This has won him no shortage of enemies. In 2019, dead crows and a fox were left hanging on his gatepost, along with a death threat; a couple of years later a Land Rover was blown up outside his house. But these attacks have only made Packham more resolute in trying to persuade other people that we already have the solution to save the natural world. New Scientist spoke to him about his latest campaign to end fossil fuel advertising and sponsorship in the UK, his upcoming TV series about evolution and how we can achieve a sustainable future on Earth. Thomas Lewton: Whenever I watch the BBC’s Springwatch, it is clear you have a deep connection with the natural world. Does being autistic help you to form this connection? Chris Packham: I think I was drawn to studying the natural world because of my ability to see things in great detail very rapidly and remember them. I have always found it easier to identify behaviours, or elucidate patterns of anatomy, physiology or whatever it happened to be. That curiosity about the natural world seemed to have been there almost inherently. My father was a marine engineer and my mother was a legal secretary, so the interest didn’t originate from them, but they certainly helped fuel it. Walking in the woods is one thing people can do that doesn’t require overconsumptionKevin Britland / Alamy Stock Photo I was an avid collector of living animals as a child. There were always things in jam jars and tanks in my bedroom. But when I got to about 12, my father bought me some binoculars. From that point onwards, I became less interested in keeping animals and more interested in watching them out in the wild. I had an obsessive interest in natural history, and it would ricochet from one species or group of species to another. I suppose we call it “focused interest” now, but I’ll stick with obsession. The more you can focus on a singular task or objective, the easier it is to exclude distractions. And then you tend to get to the bottom of what you’re trying to understand. That’s what excites your curiosity. Those are incredible abilities. Being neurodivergent can, of course, also be challenging. How would you encourage others who are autistic or who have other forms of neurodivergence to think about how they experience the world? It’s about focusing on the opportunities and attributes that you might have rather than just the challenges and difficulties and embracing where that takes you. When I was a kid, I thought I was drawn to the woods by all those things that I wanted to see or catch at the time. But in reality, I was finding solace and respite there because I wasn’t being judged by my peers. I felt very comfortable there. I found I could totally immerse myself in the experience. Many people can identify a tree by its shape, or by its leaves, or by the pattern on its bark. But I can identify trees by the sound that rain makes on their leaves if I’m sitting underneath them with my eyes closed. That’s not a tremendous skill. Anyone could learn that. But that’s the sort of degree that I want to engage with nature. You have dedicated much of your life to protecting nature. Why do you think you have faced a backlash to this activism? Like many other people, I’m asking a significant part of the population to change its mind and habits a bit more quickly than feels comfortable. Humans, as we know, are remarkable animals. We’re intelligent, adaptable, creative, imaginative, innovative. We’re brilliant in many ways – but we’re not very good at changing our minds. We are burning through Earth’s natural resourcesJim West / Alamy Stock Photo But at this point it’s very clear that unless we do change our minds and therefore our practices, we’re going to be in even deeper trouble than we are already in. I try to [point out] that there are opportunities to deal with these problems. Let’s take them while there’s still a chance to do good and find positive outcomes. A section of society is reluctant to do that. And a tiny minority will push back in an aggressive and violent way. What keeps you going in the face of this violence? I genuinely don’t care. I’m a very determined person. I can’t be swayed from a course of action if I believe it’s the right course of action. I’ve never picked a fight because I thought I could win it. I’ve always picked my fights because I thought they were the right fights to pick at the time. Winning isn’t about crossing a line or getting a medal; winning is about not giving up. At this point in time, that is the thing that you know people of my ilk – activists, campaigners, protesters – need to hold closest to their hearts. It’s very difficult at the moment. It’s very, very difficult. In what way? We’re being persecuted, you know, through an unjust legal system in terms of public protest in the UK. If we want to protest today we just don’t know where we stand. We don’t know if we will be arrested for wearing a T shirt, holding a placard or banner. We’re up against the terrible things which are happening in the US and other parts of the world when it comes to rolling back environmental protections, legislation and, indeed, environmental sciences. Ultimately, though, I still think we are a wonderful species. We have the tools, technology and abilities at our disposal to make sure that we can adapt to the problems we’ve already generated. It’s just that we don’t have anyone out there with the gumption to roll them out broadly enough and rapidly enough to make a difference. So, I’ve got to help drive that. You recently launched a petition to end fossil fuel advertising and sponsorship in the UK. Is this a major barrier to action on climate change? Well, in the UK, fossil fuel companies actually don’t spend too much money on advertising in the grand scheme of things, but they spend it in a very targeted way: they target decision-makers and politicians and others. People are being manipulated by mistruths. But what we are increasingly seeing is billions of pounds being poured into sports sponsorship [by fossil fuel companies]. It subliminally ekes its way into people’s lives, and they see those companies as doing something advantageous. It’s normalising their business. Protesters fighting Shell’s sponsorship of British CyclingAndrea Domeniconi/Alamy Live News Their business has no right to be normal any more. It’s destroying our planet. There’s no ambiguity about it. We need to stop them being able to greenwash their dirty linen in public through that sort of sponsorship. I mean, the idea that British Cycling is sponsored by Shell is like a bad joke. Cycling, something we do that is healthy, which combats carbon emissions. As is, I have to say, the continued acceptance of fossil sponsorship within some of our public institutions like the Science Museum and the British Museum, it shouldn’t be allowed. What does a sustainable future look like to you? It’s very difficult, obviously, to look into a crystal ball, given advances in technology and now the very rapid advances that we see in climate breakdown. But what I think we need is a change in mindset. Firstly, everyone goes on about economic growth. But growth comes at the cost of consumption, and we live on a finite planet. So, quite clearly, we cannot continue to grow if we’re using all those resources in an unsustainable way. “ I’m asking a significant part of the population to change its mind and habits “ People need to rethink what they want out of life. Does that consumption really make us happy? What are the rewards that we get out of life? Whether you’re into walking in the woods, whether you’re interested in art, singing, dance or whatever it happens to be that excites you in life, it doesn’t have to come at the cost of accumulating loads of stuff. What other shifts in mindset are needed? Do you think people should consider not having kids as part of achieving a sustainable population? We have to be very careful when we’re talking about overpopulation. Obviously, the more people on the planet, the more consumption takes place. The question is, of course, who’s consuming it? And in many parts of the world, where populations are growing most rapidly, that isn’t where consumption is the greatest. If everyone on Earth consumed resources at the same rate as people in the US, then we would need about five Earths to sustain this demand. We can only consume so much because of the resource poverty of other people in the world who are underusing the world’s available resources. I’m a very firm believer that when it comes to addressing climate breakdown, we must move towards a far greater degree of equality. One of the most embarrassing things about the COP climate summit is that leaders fail to agree to significantly subsidise poorer countries in the world who are suffering most from climate breakdown. It’s that sort of pervasive greed which is the handicap. On another note, you are finishing filming a BBC TV series about evolution, which is coming out next year. Evolution takes place over innumerable generations, billions of years. What can humans learn from that deep-time perspective about their place within nature? Well, firstly, how lucky we are to be here. Mutations happen unpredictably. And the fact that they occur in a place where they can actually succeed is quite odd. I mean, the chances of human life evolving are infinitesimally small. And very often evolution comes down to serendipity. Secondly, evolution gives us perspective on the damage humans are inflicting on the natural world now. We look at a number of mass extinction events in the series, and they aren’t always catastrophic. You know, a meteorite takes out all the dinosaurs, which was a disaster for the dinosaurs, but hey, we mammals had a great time in the aftermath. All of those niches that were previously unavailable, mammals evolved to fill them. So, at the moment, we’re precipitating an extermination rather than an extinction event, since it’s us that’s driving it – and we need to get our language right. But whatever we do to the planet, life’s tenacity will mean that it will survive and, you know, it will be beautiful, maybe even more beautiful all over again.

What is fracking and why is it controversial?

The government says it plans to pass legislation to permanently ban fracking for shale gas in England.

What is fracking and why is it controversial?Esme StallardClimate and science reporter, BBC NewsGetty ImagesThe government says it plans to pass legislation to permanently ban fracking for shale gas in England.A moratorium on the practice was put in place by the last government but the debate has been reopened in recent weeks after the political party Reform committed to backing fracking if it came to power.The Scottish and Welsh governments continue to remain opposed to the practise. What is fracking?Hydraulic fracturing, or fracking, is a technique for recovering gas and oil from shale rock. It involves drilling into the earth and directing a high-pressure mixture of water, sand and chemicals at a rock layer, to release the gas inside.Wells can be drilled vertically or horizontally in order to release the gas.Why is fracking controversial?The injection of fluid at high pressure into the rock can cause earth tremors - small movements in the earth's surface.In 2019, more than 120 tremors were recorded during drilling at a Cuadrilla site in Blackpool.Seismic events of this scale are considered minor and are rarely felt by people, but they are a concern to local residents.Shale gas is also a fossil fuel, and campaigners say allowing fracking could distract energy firms and governments from investing in renewable and green sources of energy.Fracking also uses huge amounts of water, which must be transported to the site at significant environmental cost.What has the government said about fracking?Government policy on fracking has see-sawed over recent years. Former Prime Minister Liz Truss looked to reintroduce the practice, despite local opposition - but this was subsequently reversed by Rishi Sunak who introduced a moratorium.In October 2025, at the Labour Party Conference, Energy Secretary Ed Miliband said the government would move to legislate against fracking, banning the practice permanently. This follows a commitment made by the Labour Party in its manifesto and further commitments by PM Sir Keir Starmer in September that the practice would be "banned for good".But Reform has said it would seek to allow the practice should it be elected, as part of its "war" on renewable developers.In his speech at the conference, Miliband said the practice was: "Dangerous and deeply harmful to our natural environment."The good news is that communities have fought back and won this fight before and will do so again," he added.ReutersAn anti-fracking protester writes messages on a wall in LancashireWhere has fracking taken place in the UK?Fracking for shale gas in the UK has only previously taken place on a small scale, due to the many public and legal challenges.However, exploration has identified large swathes of shale gas across the UK, particularly in northern England.More than 100 exploration and drilling licences were awarded to firms including Third Energy, IGas, Aurora Energy Resources and Ineos.Cuadrilla was the only company given consent to begin fracking.It drilled two wells at a site in Lancashire but faced repeated protests from local people and campaigners.In 2022, the Oil and Gas Authority told Cuadrilla to permanently concrete and abandon the wells.Could fracking lower energy bills?The UK can only meet 48% of its gas demand from domestic supplies (this would be 54% if it did not export any gas).Some MPs have claimed that restarting drilling at Cuadrilla's two existing wells could be done quickly, and would provide significant supplies.Cuadrilla claimed that "just 10%" of the gas from shale deposits in Lancashire and surrounding areas "could supply 50 years' worth of current UK gas demand".Energy experts dispute this, pointing out that the UK's shale gas reserves are held in complex layers of rock.Mike Bradshaw, professor of global energy at Warwick University, says estimates of how much shale gas the UK has are not the same as the amount of gas that could be produced commercially.But Prof Geoffrey Maitland, professor of Energy Engineering at Imperial College London, has said fracking could provide interim relief."Although shale gas will not provide an immediate solution to the energy security of the country, it could be used in the medium term to replace diminishing North Sea gas production and some gas imports," he said.Which other countries use fracking?It is thought that fracking has given energy security to the US and Canada for the next 100 years, and has presented an opportunity to generate electricity at half the CO2 emissions of coal.But the complex geology of the UK and the higher density of people makes extraction more challenging, according to experts.Fracking remains banned in numerous EU countries, including Germany, France and Spain, as well as Australia.Authorities in countries including Brazil and Argentina are split, with some banning the practice, and others allowing operations.

Engineered Microbes Pull Critical Minerals from Mining Waste

Biomining uses engineered microbes to harvest critical minerals

October 1, 20255 min readMeet the Microbes That Munch Mountains of Mining WasteBiomining uses engineered microbes to harvest critical mineralsBy Vanessa Bates Ramirez edited by Sarah Lewin FrasierEscondida Mine, located in Chile’s Atacama Desert. The copper-bearing waste is poured into the impoundment area as a liquid (green region at image center) and dries to the lighter tan and gray color. Science History Images/Alamy Stock PhotoAt the northern edge of Chile’s Atacama Desert sits a pile of rocks that’s so big that you can see it from space—and it’s teeming with invisible activity. Billions of microbes are hard at work dissolving compounds in this giant mound of crushed ore from Escondida, the biggest copper mine on the planet.“Microbes are the world’s oldest miners,” says Liz Dennett, founder and CEO of the start-up Endolith Mining, based near Denver, Colo. “They’ve had billions of years to become incredibly good at eating rocks.”Scientists at Endolith and elsewhere are engineering microbes to get even better at this process, called biomining—to work faster, extract more copper and even pull out other kinds of minerals. Endolith tests different microbes to see which are most fit for the job and then exposes them to harsh conditions to further strengthen them. “Think of it like a superhero training camp,” Dennett says. In May the company’s engineered microbes demonstrated copper extraction superior to microbes found in nature; its first field deployments are scheduled for later this year.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing.

Barstow is leading a project called the Microbe-Mineral Atlas that catalogs microorganisms, their genes and how they interact with minerals. The project’s goal is to build genetically engineered microorganisms that can effectively mine critical metals.As many countries transition to renewable energy, they will require fewer fossil fuels but more minerals such as lithium, cobalt, copper, nickel and zinc. These are not only needed for wind turbines, solar panels and batteries; they’re also crucial for the laptops and cell phones we use every day. Copper demand, in particular, is set to skyrocket. Forecasts show we’ll need more copper in the next 30 years than has been mined throughout all of history. Much of the low-hanging fruit—that is, high-grade ore—has been picked, and mines have to work a lot harder than before to get the same quantity.Trucks hauling earth from Escondida.Cavan Images/Alamy Stock PhotoConventional mining techniques are resource-intensive, expensive and harmful to the environment. After using explosives and heavy machinery to extract ore from the earth, mining companies must isolate and purify the minerals in question. Often, that means breaking chemical bonds that keep minerals bound to sulfur in sulfide ores. This is most commonly done using heat through a process called smelting or acid through a process called leaching. Smelting requires extremely high temperatures, reached by burning fossil fuels or using a lot of electricity. On top of the carbon dioxide emissions this generates, burning sulfur produces toxic sulfur dioxide gas. Acid leaching, meanwhile, carries the risk of acid mine drainage, where fluids contaminate rivers or groundwater and harm the surrounding ecosystem. The sulfuric acid used for this process can cause harm before it even reaches mines. “Production of sulfuric acid is very nasty,” Dennett says. “There’s a lot of secondary and tertiary effects on the environment.”Microbes can do the same work as heat and acid, but their cost and environmental impact are much lower. “Microbes use at least six different mechanisms for biomining,” Barstow says. The most common is an oxidation-reduction reaction, or redox reaction, in which microbes break the chemical bonds in a sulfide ore by “eating” their sulfur and iron. This releases the minerals in the ore, breaking them down until they can dissolve in water. The mineral-rich solution is collected in a pond after it is drained from the rock and is then exposed to solvents and electricity that attract the minerals like a magnet while leaving water, acid and impurities behind.The microbes still need a small amount of sulfuric acid to kick-start the process of breaking down the ore. Piles of rock such as the one at Chile’s Escondida mine—called heap leaches—are sprayed with an acid-water mixture that only needs to be added once because microbes make more acid naturally as they break the ore’s chemical bonds. “Replacing [most] sulfuric acid is a big economic benefit, as it can often be the largest operating expense for a mine,” says Sasha Milshteyn, founder of Transition Biomining, a company that analyzes the DNA of microbes found in ores to develop custom additives for increased copper recovery.Though the process avoids toxic gas emissions, uses less energy and water than conventional methods and minimizes hazardous chemicals, it has its limitations. It’s slower than traditional mining: while smelting can take hours to days, and acid leaching takes days to weeks, microbes do their work over several months. They’re sensitive to pH, temperature, and moisture levels and can be killed off or slowed down by changes in any of these. And they still produce acidic solutions that need to be contained and treated. As Barstow puts it, “Biomining won’t be an environmental panacea; it will just be quite a bit better than what we do now.”The real promise of biomining is that it can squeeze more out of rocks than conventional methods do. “Modern mining technologies ‘skim the cream’ of economically valuable metals from a deposit and leave everything else behind in [waste rock called] tailings,” Barstow says.That waste is worth far more than it usually gets credit for. A study recently published in Science found that recovering the minerals in waste from existing U.S. mines could meet nearly all of the country’s critical mineral needs; recovering just 1 percent would substantially reduce import reliance for many elements. “If large mines just added additional recovery circuits to their process, this could bring needed minerals into production relatively quickly,” says the study’s lead author Elizabeth Holley, a mining engineer at the Colorado School of Mines.Copper mine waste can hold bits of tellurium, cobalt or zinc; coal ash can contain lithium, manganese and rare earth elements. The quantities are too small for conventional mines to bother with, but they’re not too small for microbes. Besides being used in heap leaches or pumped straight into the ground, microbes can be applied directly to waste streams, where they can pull out tiny amounts of minerals that can add up to be significant.Microbes may be the world’s oldest miners, but biomining as a technology is still new, Milshteyn notes, and doesn’t yet leverage the full complexity of microbial ecosystems. “The heaps that perform best in the field have thriving ecosystems of diverse microbes working together,” he says. “I think the next generation of biomining has to contend with that complexity.”It’s Time to Stand Up for ScienceIf you enjoyed this article, I’d like to ask for your support.

This story was originally published by Guardian and is reproduced here as part of the Climate Desk collaboration. The White House will open 13.1 million acres of public land to coal mining while providing $625 million for coal-fired power plants, the Trump administration has announced. The efforts came as part of a suite of initiatives from the Department of the Interior, Department of Energy, and Environmental Protection Agency, aimed at reviving the flagging coal sector. Coal, the most polluting and costly fossil fuel, has been on a rapid decline over the past 30 years, with the US halving its production between 2008 and 2023, according to the Energy Information Administration (EIA). “This is an industry that matters to our country,” Interior Secretary Doug Burgum said in a livestreamed press conference on Monday morning, alongside representatives from the other two departments. “It matters to the world, and it’s going to continue to matter for a long time.” “This is a colossal waste of our money at a time when the federal government should be spurring along the new energy sources.” Coal plants provided about 15 percent of US electricity in 2024—a steep fall from 50 percent in 2000—the EIA found, with the growth of gas and green power displacing its use. Last year, wind and solar produced more electricity than coal in the US for the first time in history, according to the International Energy Agency, which predicts that could happen at the global level by the end of 2026. Despite its dwindling role, Trump has made the reviving the coal sector a priority of his second term amid increasing energy demand due to the proliferation of artificial intelligence data centers. “The Trump administration is hell-bent on supporting the oldest, dirtiest energy source. It’s handing our hard-earned tax dollars over to the owners of coal plants that cost more to run than new, clean energy,” said Amanda Levin, director of policy analysis at the national environmental nonprofit Natural Resources Defense Council. “This is a colossal waste of our money at a time when the federal government should be spurring along the new energy sources that can power the AI boom and help bring down electricity bills for struggling families.” The administration’s new $625 million investment includes $350 million to “modernize” coal plants, $175 million for coal projects it claims will provide affordable and reliable energy to rural communities, and $50 million to upgrade wastewater management systems to extend the lifespan of coal plants. The efforts follow previous coal-focused initiatives from the Trump administration, which has greenlit mining leases while fast-tracking mining permits. It has also prolonged the life of some coal plants, exempted some coal plants from EPA rules, and falsely claimed that emissions from those plants are “not significant.” The moves have sparked outrage from environmental advocates who note that coal pollution has been linked to hundreds of thousands of deaths across the past two decades. One study estimated that emissions from coal costs Americans $13-$26 billion a year in additional ER visits, strokes and cardiac events, and a greater prevalence and severity of childhood asthma events.

Air Pollution Worsens Sleep Apnea

By Dennis Thompson HealthDay ReporterWEDNESDAY, Oct. 1, 2025 (HealthDay News) — Air pollution could be making matters worse for people with sleep apnea, according to a new study.Sleep apnea patients have more episodes of reduced or stopped breathing during their slumber in areas with heavier air pollution, researchers reported Tuesday at an European Respiratory Society meeting in Amsterdam.Further, these sleep apnea episodes increased as air became more polluted, researchers found.“We confirmed a statistically significant positive association between average long-term exposure to air pollution, specifically fine particles known as PM10, and the severity of obstructive sleep apnea,” researcher Martino Pengo, an associate professor from the University of Milano-Bicocca in Italy, said in a news release.PM10 particles are less than 10 micrometers in diameter, according to the U.S. Environmental Protection Agency. By comparison, a human hair is 50 to 70 micrometers wide.People with sleep apnea snore loudly and their breathing starts and stops during the night, disturbing their sleep. The condition is known to increase risk of high blood pressure, stroke, heart disease and type 2 diabetes, according to the Mayo Clinic.For the study, researchers tracked more than 19,000 patients with sleep apnea from 25 cities in 14 countries. The team compared the patients’ apnea data from sleep studies with records of particle pollution in the air where they live.Results showed that the number of respiratory events — breathing slowing or stopping — per hour of sleep increased by 0.41 for every one-unit increase in PM10 particle pollution.“This effect may seem small for an individual, but across entire populations it can shift many people into higher-severity categories, making it meaningful from a public health perspective,” Pengo said.Researchers also found the link between particle pollution and sleep apnea varied in strength between cities. People in Lisbon, Paris and Athens were more affected by air pollution.“In some cities, the impact was stronger; in others, it was weaker or even absent,” Pengo said. “These regional differences might be due to things like local climate, the type of pollution or even how health care systems detect obstructive sleep apnea.”Sophia Schiza, head of the European Respiratory Society’s expert group on sleep disordered breathing, said that “for people with obstructive sleep apnea, especially those living in cities with high levels of air pollution, this study is important as it suggests pollution could be making their condition worse.”The study strengthens the connection between environmental health and sleep medicine, added Schiza, a professor of pulmonology at the University of Crete in Greece who was not involved in the research. “It reminds us that tackling air pollution isn't just good for the planet, it's also vital for our lungs and our sleep quality too,” she said in a news release.Findings presented at medical meetings should be considered preliminary until published in a peer-reviewed journal.SOURCE: European Respiratory Society, news release, Sept. 30, 2025Copyright © 2025 HealthDay.

Government shutdown means 90% of EPA staff won't be working

The EPA will pause research work, grants, permits and inspections while the government is shut down. Nearly all staff will stop working. Some may not be rehired.

The shutdown of the U.S. government could have ripple effects for human health and the environment as an already weakened Environmental Protection Agency will see nearly all of its staff furloughed and many of its operations paused. The first shutdown in six years went into effect late Tuesday and requires federal agencies to stop all nonessential work. Most EPA work is considered only partially essential under federal rules. Nearly 90% of EPA staff will be furloughed; only 1,732 of 15,166 employees will report to work, according to the agency’s most recent shutdown contingency plan, issued in September.Immediate environmental hazard work is likely to continue, but longer-term efforts such as research, permitting, writing new rules and pollution enforcement will largely freeze. Experts note that the shutdown comes as the agency already has seen significant cuts as part of the Trump administration’s efforts to restructure the federal government and save taxpayers money. About 4,000 EPA employees, or a quarter of its workforce, have been fired or have taken a buyout this year. “The shutdown has already been happening for months,” said Marc Boom, a former senior policy advisor with the EPA who now serves as senior advisor with the Environmental Protection Network, a bipartisan group of more than 700 former EPA employees based in Washington, D.C.Many activities will halt, including research and the publication of research results, and the issuance of new grants, contracts and permits, according to the agency. Critically, civil enforcement inspections — on-site visits to facilities to check their compliance with environmental regulations — will also cease. Whether cleanup work at hazardous waste areas known as Superfund sites will continue will be decided case by case. At sites where stopping would pose an imminent threat to human life, work will continue, but at others, it will pause, according to the agency.Preparing for, preventing and responding to environmental disasters such as oil spills and chemical releases, known as emergency response readiness operations, will not stop. Freezers, animals, plants and other assets in research labs will continue to be maintained. In a statement to The Times before the shutdown, EPA officials blamed Democrats for the quagmire and said the agency will continue to strive to meet its mission. The impasse came as Democrats demanded healthcare provisions in the budget while Republicans pushed for a short-term budget extension without policy changes.“Congressional Democrats are not only unwilling to vote for a clean funding bill, but their goal is to inflict as much pain on the American people as possible,” the EPA said. “Americans made their voices heard last November; Democrats must respect the will of the people. ... EPA will work to fulfill our statutory obligations, emergency response efforts, and Administration priorities.” But the agency has already lost considerable expertise through its staff cuts and restructuring, which have lessened its ability to respond to both emerging and existing threats, according to Linda Birnbaum, former director of the National Institute for Environmental Health Sciences and the National Toxicology Program. “The additional loss of people will essentially take us to a point where EPA will be almost unable to complete its mission,” Birnbaum said in a statement. Since Trump took office in January, the EPA has canceled hundreds of environmental grants; rolled back protections against pesticides, forever chemicals and fossil fuel emissions; issued exemptions for large polluters, eliminated its office of Research and Development and announced plans to repeal the endangerment finding, which affirms that greenhouse gases are harmful to human health and the environment, among other efforts.The furloughs at EPA could become permanent. A recent memo from the federal Office of Management and Budget directed federal agencies to prepare for mass layoffs in the event of a government shutdown, implying people may not be rehired.“If you’ve already cut the staff by 4,000 and more is to come from the shutdown and from further [reductions in force], then there will be even less protections,” said Vicki Arroyo, a former EPA associate administrator for policy who served under both the Biden and Reagan administrations. Arroyo recalled the challenges of maintaining the agency’s core functions during the last federal shutdown six years ago, when she was the only one of about 160 people on her team who remained at work. Duties such as economic analyses, permitting for energy projects such as offshore wind and National Environmental Policy Act reviews were among those to suffer, she said, and could be hit even harder this time around.“When EPA funding and staffing are undercut, it doesn’t just hurt these public servants, it hurts us all,” Arroyo said. “Without a functioning EPA, we can’t trust that the water out of our tap is safe ... and without EPA staff on duty, we can’t rely on EPA to monitor and protect air quality so that children without asthma and others with respiratory conditions are safe from pollution.” She and other experts also feared that less support and oversight from the federal government would result in diminished quality control at the local level, as many federal laws are delegated to states. In California, much will depend on the length of the shutdown, according to H.D. Palmer, spokesman for the California Department of Finance. A shutdown lasting only a few days would probably have minimal effect on the California EPA.Specifically, Palmer said many California environmental programs that were funded under the Biden administration should be able to continue even if there is a brief lapse in appropriations, such as brownfield project grants and the state’s Clean Water State Revolving Fund. However, a protracted shutdown could lead to delays in new project grants or permits being issued.“We’re going to continue to assess it depending on how long this thing goes on,” Palmer said. The EPA is not the only environmental agency that will face challenges. The U.S. Forest Service, the Federal Emergency Management Agency, the National Oceanic and Atmospheric Administration and the National Park Service are also bracing for interruptions under the shutdown in addition to cuts this year.
