Nearly Half of Americans Breathe Unhealthy Air, New Report Finds

FRIDAY, April 25, 2025 (HealthDay News) —Breathing the air in nearly half of the United States could be putting your health at risk.A new American Lung Association report shows that 156 million people live in areas with unhealthy air.The group’s annual "State of the Air" report found that smog and soot pollution are getting worse, not better. The report looked at air quality data from 2021 to 2023. It found that 25 million more people than in the group's last report were breathing "unhealthy levels of air pollution." That's more than in any other "State of the Air" report in the last decade, the association said.Since the Clean Air Act became law in 1970, air pollution has gone down overall, said Laura Kate Bender, an assistant vice president at the lung association, told CBS News."The challenge is that over the last few years, we're starting to see it tick back up again and that's because of climate change, in part," she said. "Climate change is making some of those conditions for wildfires and extreme heat that drive ozone pollution worse for a lot of the country."The city with the worst year-round and short-term particle pollution? Bakersfield, California, for the sixth year in a row.What's more, it was ranked third worst for high ozone days. In contrast, Casper, Wyoming, was listed as the cleanest city for year-round particle pollution, CBS News said.Here are the top 10 cities with the worst year-round particle pollution, according to the association:Bakersfield-Delano, Calif. Visalia, Calif. Fresno-Hanford-Corcoran, Calif. Eugene-Springfield, Ore. Los Angeles-Long Beach, Calif. Detroit-Warren-Ann Arbor, Mich. San Jose-San Francisco-Oakland, Calif. Houston-Pasadena, Texas Cleveland-Akron-Canton, Ohio Fairbanks-College, Ark. The report warned that pollution isn't just an issue in the west. Extreme heat and wildfires are spreading pollution across the country.In fact, smoke from Canada's wildfires in 2023 caused unhealthy air quality even in the eastern parts of the U.S., the report pointed out.Some of the findings came as a surprise, according to Kevin Stewart, the association’s environmental health director."I think we knew that the wildfire smoke would have an impact on air quality in the United States," he told CBS News. "I think we were surprised at the Lung Association by how strong the effect was, especially in the northeastern quadrant of the continental United States." Last month, the U.S. Environmental Protection Agency (EPA) announced it will roll back 31 environmental rules, including ones pertaining to vehicle emissions, CBS News reported.Bender said that puts decades of progress at risk."Unfortunately, we see that everything that makes our air quality better is at risk," she said. "The EPA is at risk — the agency that is protecting our health — through staff cuts, funding cuts. The regulations that have cleaned up our air over time are at risk of being cut. If we see all those cuts become reality, it's gonna have a real impact on people's health by making the air they breathe dirtier."Lee Zeldin, the EPA administrator, argued that, instead, the deregulation will drive "a dagger straight into the heart of the climate change religion to drive down cost of living for American families, unleash American energy, bring auto jobs back to the U.S. and more," according to CBS News."This air pollution is causing kids to have asthma attacks, making people who work outdoors sick and unable to work, and leading to low birth weight in babies," Kezia Ofosu Atta, the Lung Association’s advocacy director, told CBS News.The report also found that Black Americans are more likely to suffer serious health problems from air pollution.SOURCE: CBS News, April 23, 2025Copyright © 2025 HealthDay.

From Greenland to Ghana, Indigenous youth work for climate justice

“No matter what happens we will stand and we will fight, and we will keep pushing for solutions.”

For the last week,  Indigenous leaders from around the world have converged in New York for the United Nations Permanent Forum on Indigenous Issues, or UNPFI. It’s the largest global gathering of Indigenous peoples and the Forum provides space for participants to bring their issues to international authorities, often when their own governments have refused to take action. This year’s Forum focuses on how U.N. member states’ have, or have not, protected the rights of Indigenous peoples, and conversations range from the environmental effects of extractive industries, to climate change, and violence against women. The Forum is an intergenerational space. Young people in attendance often work alongside elders and leaders to come up with solutions and address ongoing challenges. Grist interviewed seven Indigenous youth attending UNPFII this year hailing from Africa, the Pacific, North and South America, Asia, Eastern Europe, and the Arctic. Joshua Amponsem, 33, is Asante from Ghana and the founder of Green Africa Youth Organization, a youth-led group in Africa that promotes energy sustainability. He also is the co-director of the Youth Climate Justice Fund which provides funding opportunities to bolster youth participation in climate change solutions.  Since the Trump administration pulled all the funding from the U.S. Agency for International Development, or USAID, Amponsem has seen the people and groups he works with suffer from the loss of financial help. Courtesy of Joshua Amponsem It’s already hard to be a young person fighting climate change. Less than one percent of climate grants go to youth-led programs, according to the Youth Climate Justice Fund.   “I think everyone is very much worried,” he said. “That is leading to a lot of anxiety.”  Amponsem specifically mentioned the importance of groups like Africa Youth Pastoralist Initiatives — a coalition of youth who raise animals like sheep or cattle. Pastoralists need support to address climate change because the work of herding sheep and cattle gets more difficult as drought and resource scarcity persist, according to one report.  “No matter what happens we will stand and we will fight, and we will keep pushing for solutions,” he said. Janell Dymus-Kurei, 32, is Māori from the East Coast of Aotearoa New Zealand. She is a fellow with the Commonwealth Fund, a group that promotes better access to healthcare for vulnerable populations. At this year’s UNPFII, Dymus-Kurei hopes to bring attention to legislation aimed at diminishing Māori treaty rights. While one piece of legislation died this month, she doesn’t think it’s going to stop there. She hopes to remind people about the attempted legislation that would have given exclusive Maori rights to everyone in New Zealand. Courtesy of Janell Dymus-Kurei The issue gained international attention last Fall when politician Hana-Rawhiti Maipi-Clarke performed a Haka during parliament, a traditional dance that was often done before battle. The demonstration set off other large-scale Māori protests in the country.  “They are bound by the Treaty of Waitangi,” she said. Countries can address the forum, but New Zealand didn’t make it to the UNPFII.  “You would show up if you thought it was important to show up and defend your actions in one way, shape, or form,” she said. This year, she’s brought her two young children — TeAio Nitana, which means “peace and divinity” and Te Haumarangai, or “forceful wind”. Dymus-Kurei said it’s important for children to be a part of the forum, especially with so much focus on Indigenous women. “Parenting is political in every sense of the word,” she said. Avery Doxtator, 22, is Oneida, Anishinaabe and Dakota and the president of the National Association of Friendship Centres, or NAFC, which promotes cultural awareness and resources for urban Indigenous youth throughout Canada’s territories. She attended this year’s Forum to raise awareness about the rights of Indigenous peoples living in urban spaces. The NAFC brought 23 delegates from Canada this year representing all of the country’s regions. It’s the biggest group they’ve ever had, but Doxtator said everyone attending was concerned when crossing the border into the United States due to the Trump Administration’s border and immigration restrictions. Taylar Dawn Stagner “It’s a safety threat that we face as Indigenous peoples coming into a country that does not necessarily want us here,” she said. “That was our number one concern. Making sure youth are safe being in the city, but also crossing the border because of the color of our skin.” The United Nations Declaration on the Rights of Indigenous Peoples, or UNDRIP, protects Indigenous peoples fundamental rights of self-determination, and these rights extend to those living in cities, perhaps away from their territories. She said that she just finished her 5th year on the University of Toronto’s Water Polo Team, and will be playing on a professional team in Barcelona next year.  Around half of Indigenous peoples in Canada live in cities. In the United States around 70 percent live in cities. As a result, many can feel disconnected from their cultures, and that’s what she hopes to shed light on at the forum — that resources for Indigenous youth exist even in urban areas. Liudmyla Korotkykh, 26, is Crimean Tatar from Kyiv, one of the Indigenous peoples of Ukraine. She spoke at UNPFII about the effects of the Ukraine war on her Indigenous community. She is a manager and attorney at the Crimean Tatar Resource Center. The history of the Crimean Tatars are similar to other Indigenous populations. They have survived colonial oppression from both the Russian Empire and the Soviet Union — and as a result their language and way of life is constantly under threat. Crimea is a country that was annexed by Russia around a decade ago.  Taylar Dawn Stagner In 2021, President Zelensky passed legislation to establish better rights for Indigenous peoples, but months later Russia continued its campaign against Ukraine.  Korotkykh said Crimean Tatars have been conscripted to fight for Russia against the Tatars that are now in Ukraine.  “Now we are in the situation where our peoples are divided by a frontline and our peoples are fighting against each other because some of us joined the Russian army and some joined the Ukrainian army,” she said.  Korotkykh said even though many, including the Trump Administration, consider Crimea a part of Russia, hopes that Crimean Tatars won’t be left out of future discussions of their homes.  “This is a homeland of Indigenous peoples. We don’t accept the Russian occupation,” she said. “So, when the [Trump] administration starts to discuss how we can recognize Crimea as a part of Russia, it is not acceptable to us.” Toni Chiran, 30, is Garo from Bangladesh, and a member of the Bangladesh Indigenous Youth Forum, an organization focused on protecting young Indigenous people. The country has 54 distinct Indigenous peoples, and their constitution does not recognize Indigenous rights.  In January, Chiran was part of a protest in Dhaka, the capital of Bangladesh, where he and other Indigenous people were protesting how the state was erasing the word “Indigenous” — or Adivasi in Hindi — from text books. Chiran says the move is a part of an ongoing assault by the state to erase Indigenous peoples from Bangladesh. Courtesy of Toni Chiran He said that he sustained injuries to his head and chest during the protest as counter protesters assaulted their group, and 13 protesters sustained injuries. He hopes bringing that incident, and more, to the attention of Forum members will help in the fight for Indigenous rights in Bangladesh. “There is an extreme level of human rights violations in my country due to the land related conflicts because our government still does not recognize Indigenous peoples,” he said.  The student group Students for Sovereignty were accused of attacking Chiran and his fellow protesters. During a following protest a few days later in support of Chiran and the others injured Bangladesh police used tear gas and batons to disperse the crowd.  “We are still demanding justice on these issues,” he said. Aviaaija Baadsgaard, 27, is Inuit and a member of the Inuit Circumpolar Council Youth Engagement Program, a group that aims to empower the next generation of leaders in the Arctic. Baadsgaard is originally from Nuunukuu, the capital of Greenland, and this is her first year attending the UNPFII. Just last week she graduated from the University of Copenhagen with her law degree. She originally began studying law to help protect the rights of the Inuit of Greenland.. Recently, Greenland has been a global focal point due to the Trump Administration’s interest in acquiring the land and its resources – including minerals needed for the green transition like lithium and neodymium: both crucial for electric vehicles. “For me, it’s really important to speak on behalf of the Inuit of Greenland,” Baadsgaard said. Taylar Dawn Stagner Greenland is around 80 percent Indigenous, and a vast majority of the population there do not want the Greenland is around 80 percent Indigenous, and a vast majority of the population there do not want the U.S. to wrest control of the country from the Kingdom of Denmark. Many more want to be completely independent.  “I don’t want any administration to mess with our sovereignty,” she said.  Baadsgaard said her first time at the forum has connected her to a broader discussion about global Indigenous rights — a conversation she is excited to join. She wants to learn more about the complex system at the United Nations, so this trip is about getting ready for the future. Cindy Sisa Andy Aguinda, 30, is Kitchwa from Ecuador in the Amazon. She is in New York to talk about climate change, women’s health and the climate crisis. She spoke on a panel with a group of other Indigenous women about how the patriarchy and colonial violence affect women at a time of growing global unrest. Especially in the Amazon where deforestation is devastating the forests important to the Kitchwa tribe.  She said international funding is how many protect the Amazon Rainforest. As an example, last year the United States agreed to send around 40 million dollars to the country through USAID — but then the Trump administration terminated most of the department in March. Courtesy of Cindy Sisa Andy Aguinda “To continue working and caring for our lands, the rainforest, and our people, we need help,” she said through a translator. Even when international funding goes into other countries for the purposes to protect Indigenous land, only around 17 percent ends up in the hands of Indigenous-led initiatives. “In my country, it’s difficult for the authorities to take us into account,” she said.  She said despite that she had hope for the future and hopes to make it to COP30 in Brazil, the international gathering that addresses climate change, though she will probably have to foot the bill herself. She said that Indigenous tribes of the Amazon are the ones fighting everyday to protect their territories, and she said those with this relationship with the forest need to share ancestral knowledge with the world at places like the UNPFII and COP30.  “We can’t stop if we want to live well, if we want our cultural identity to remain alive,” she said.

Umbilical Cord Could Contain Clues For Child's Future Health

By Dennis Thompson HealthDay ReporterFRIDAY, April 25, 2025 (HealthDay News) -- Doctors might be able to predict a newborn's long-term health outlook, by analyzing their umbilical cord blood, a new study says.Genetic clues found in cord blood can offer early insight into which infants are at higher risk for health problems like diabetes, stroke and liver disease later in life, researchers will report at the upcoming Digestive Disease Week meeting in San Diego.“We’re seeing kids develop metabolic problems earlier and earlier, which puts them at higher risk for serious complications as adults,” lead researcher Dr. Ashley Jowell, a resident physician in internal medicine at Duke University Health System in Durham, N.C., said in a news release. “If we can identify that risk at birth, we may be able to prevent it.”For the study, researchers performed genetic analysis on the umbilical cord blood of 38 children enrolled in a long-term study based in North Carolina.The analysis looked for chemical patterns in infants’ DNA that switch genes on or off. When these switches occur in critical parts of DNA, their health effects can persist through fetal development and into later life.The research team compared these DNA changes to the kids’ health at ages 7 to 12, and identified multiple areas where genes in cord blood predicted health problems in childhood.For example, changes in a gene called TNS3 were linked to fatty liver, liver inflammation or damage, and excess belly fat as measured by waist-to-hip ratio, results show.Changes in other genes were connected to blood pressure, waist-to-hip ratio, and liver inflammation or damage, researchers said.“These epigenetic signals are laid down during embryonic development, potentially influenced by environmental factors such as nutrition or maternal health during pregnancy,” co-researcher Dr. Cynthia Moylan, an associate professor in the division of gastroenterology at Duke University Health System, said in a news release.Researchers noted that the sample size was small, but the links so powerful that these findings warrant further investigation. A larger follow-up study funded by the National Institutes of Health is underway.“If validated in larger studies, this could open the door to new screening tools and early interventions for at-risk children,” Moylan added.Jowell said disease may be preventable even with these markers."Just because you're born with these markers doesn't mean disease is inevitable," she said. "But knowing your risk earlier in life could help families and clinicians take proactive steps to support a child’s long-term health."Researchers are scheduled to present their findings May 4. Findings presented at medical meetings are considered preliminary until published in a peer-reviewed journal.SOURCE: American Gastroenterological Association, news release, April 25, 2025Copyright © 2025 HealthDay.

Hundreds of life-size animal puppets have begun a 20,000km (12,400 mile) journey from central Africa to the Arctic Circle as part of an ambitious project created by the team behind Little Amal, the giant puppet of a Syrian girl that travelled across the world.The public art initiative called The Herds, which has already visited Kinshasa and Lagos, will travel to 20 cities over four months to raise awareness of the climate crisis.It is the second major project from The Walk Productions, which introduced Little Amal, a 12-foot puppet, to the world in Gaziantep, near the Turkey-Syria border, in 2021. The award-winning project, co-founded by the Palestinian playwright and director Amir Nizar Zuabi, reached 2 million people in 17 countries as she travelled from Turkey to the UK.The Herds’ journey began in Kinshasa’s Botanical Gardens on 10 April, kicking off four days of events. It moved on to Lagos, Nigeria, the following week, where up to 5,000 people attended events performed by more than 60 puppeteers.On Friday the streets of Dakar in Senegal will be filled with more than 40 puppet zebras, wildebeest, monkeys, giraffes and baboons as they run through Médina, one of the busiest neighbourhoods, where they will encounter a creation by Fabrice Monteiro, a Belgium-born artist who lives in Senegal, and is known for his large-scale sculptures. On Saturday the puppets will be part of an event in the fishing village of Ngor.The Herds’ 20,000km journey began in Kinshasa, the Democratic Republic of the Congo. Photograph: Berclaire/walk productionsThe first set of animal puppets was created by Ukwanda Puppetry and Designs Art Collective in Cape Town using recycled materials, but in each location local volunteers are taught how to make their own animals using prototypes provided by Ukwanda. The project has already attracted huge interest from people keen to get involved. In Dakar more than 300 artists applied for 80 roles as artists and puppet guides. About 2,000 people will be trained to make the puppets over the duration of the project.“The idea is that we’re migrating with an ever-evolving, growing group of animals,” Zuabi told the Guardian last year.Zuabi has spoken of The Herds as a continuation of Little Amal’s journey, which was inspired by refugees, who often cite climate disaster as a trigger for forced migration. The Herds will put the environmental emergency centre stage, and will encourage communities to launch their own events to discuss the significance of the project and get involved in climate activism.The puppets are created with recycled materials and local volunteers are taught how to make them in each location. Photograph: Ant Strack“The idea is to put in front of people that there is an emergency – not with scientific facts, but with emotions,” said The Herds’ Senegal producer, Sarah Desbois.She expects thousands of people to view the four events being staged over the weekend. “We don’t have a tradition of puppetry in Senegal. As soon as the project started, when people were shown pictures of the puppets, they were going crazy.”Little Amal, the puppet of a Syrian girl that has become a symbol of human rights, in Santiago, Chile on 3 January.

UK spending watchdog censures water firms and regulators over sewage failings

NAO finds regulatory gaps have enabled overspending on infrastructure building while not improving sewage worksWater companies have been getting away with failures to improve sewage works and overspending because of regulatory problems, a damning report by the government’s spending watchdog has found.Firms have overspent on infrastructure building, the National Audit Office (NAO) found, with some of these costs being added to consumers’ bills.

Water companies have been getting away with failures to improve sewage works and overspending because of regulatory problems, a damning report by the government’s spending watchdog has found.Firms have overspent on infrastructure building, the National Audit Office (NAO) found, with some of these costs being added to consumers’ bills. The Guardian this week reported Ofwat and the independent water commission are investigating water firms for spending up to 10 times as much on their sewage works and piping as comparable countries.Bills in England and Wales are rising by £123 on average this year, and will go up further over the next five years, so that companies can fix ageing sewage infrastructure and stop spills of human waste from contaminating rivers and seas. Several water firms have complained to the Competition and Markets Authority because they want the regulator to allow them to increase bills even further.Only 1% of water companies’ actions to improve environmental performance, such as improving sewer overflows, have been inspected by the Environment Agency, the authors of the NAO report said. They also found there was no regulator responsible for proactively inspecting wastewater assets to prevent further environmental harm.The report, which audited the three water regulators, Ofwat, the Environment Agency, and the Drinking Water Inspectorate, as well as the Department for Environment Food and Rural Affairs, also found the regulators did not have a good understanding of the condition of infrastructure assets such as leaking sewers and ageing sewage treatment facilities as they do not have a set of metrics to assess their condition.Gareth Davies, the head of the NAO, said: “Given the unprecedented situation facing the sector, Defra and the regulators need to act urgently to address industry performance and resilience to ensure the sector can meet government targets and achieve value for money over the long term for bill payers.”Despite the huge costs of infrastructure, the water companies have moved slowly meaning that at the current rate, it would take 700 years to replace the entire existing water network, the report found. Regulatory gaps and a lack of urgency about replacing old and malfunctioning infrastructure has caused a “rising tide of risk” in the sector, which is contributing to increasing bills for customers, the report warned.It also criticised the lack of a national plan for water supply and recommended that Defra must understand the costs and deliverability of its plans, alongside the impact they would have on customers’ bills.Several of the issues raised by the NAO, including concerns about weak infrastructure, have come to the fore in the debate over the future of Thames Water, the country’s largest water company with 16 million customers. Thames, which is under significant financial pressure with almost £20bn in debt, needs to secure fresh investment within months. Questions over the state of Thames’s infrastructure and regulatory punishment it could face for its failures have dogged the process of winning fresh funds. Meanwhile, Ofwat has also rejected its requests to raise bills by as much as 59%, instead allowing a 35% increase over the next five years.The government set up the independent water commission (IWC) last year to investigate how the water industry operated and whether regulation was fit for purpose.Sir Geoffrey Clifton-Brown, the Tory chair of the Commons public accounts committee, said: “Today’s NAO report lays bare the scale of the challenges facing the water sector – not least the real prospect of water shortfall without urgent action.“The consequences of government’s failure to regulate this sector properly are now landing squarely on bill payers who are being left to pick up the tab. After years of under-investment, pollution incidents and water supply issues, it is no surprise that consumer trust is at an all-time low.

Defra and the regulators must focus on rebuilding public confidence and ensure the sector can attract the long-term investment it desperately needs.”An Environment Agency spokesperson said: “We recognise the significant challenges facing the water industry. That is why we will be working with Defra and other water regulators to implement the report’s recommendations and update our frameworks to reflect its findings.”An Ofwat spokesperson added: “We agree with the NAO’s recommendations for Ofwat and we continue to progress our work in these areas, and to contribute to the IWC wider review of the regulatory framework. We also look forward to the IWC’s recommendations and to working with government and other regulators to better deliver for customers and the environment.”A Defra spokesperson said: “The government has taken urgent action to fix the water industry – but change will not happen overnight. We have put water companies under tough special measures through our landmark Water Act.”Water UK, which represents the water companies, has been contacted for comment.

Only three people prosecuted for covering up illegal sewage spills

Employees of water firms who obstruct investigations into spills could face jail, as new rules come into force on FridayWater company bosses have entirely escaped punishment for covering up illegal sewage spills, government figures show, as ministers prepare to bring in a new law threatening them with up to two years in prison for doing so.Only three people have ever been prosecuted for obstructing the Environment Agency in its investigations into sewage spills, officials said, with none of them receiving even a fine.

Water company bosses have entirely escaped punishment for covering up illegal sewage spills, government figures show, as ministers prepare to bring in a new law threatening them with up to two years in prison for doing so.Only three people have ever been prosecuted for obstructing the Environment Agency in its investigations into sewage spills, officials said, with none of them receiving even a fine.Officials said the data shows why the water regulator has found it so difficult to stop illegal spills, which happen when companies dump raw sewage during dry weather. The Environment Agency has identified hundreds of such cases since 2020.Steve Reed, the environment secretary, said: “Bosses must face consequences if they commit crimes – there must be accountability. From today, there will be no more hiding places.“Water companies must now focus on cleaning up our rivers, lakes and seas for good.”Water companies dumped a record amount of sewage into rivers and coastal waters last year, mostly because wet weather threatened to wash sewage back into people’s homes.Data released last month by the Environment Agency revealed companies had discharged untreated effluent for nearly 4m hours during 2024, a slight increase on the previous year.But companies have also illegally dumped sewage during dry weather. Data released to the Telegraph last year under freedom of information rules shows regulators had identified 465 illegal sewage spills since 2020, with a further 154 under investigation as potentially illegal spills.Britain’s polluted waterways became a major issue at last year’s election, with Labour promising to end what it called the “Tory sewage scandal”.Government sources say one reason illegal spills have been allowed to continue is that regulators have faced obstruction when investigating them.In 2019, three employees at Southern Water were convicted of hampering the Environment Agency when it was trying to collect data as part of an investigation into raw sewage spilled into rivers and on beaches in south-east England.The maximum punishment available in that case was a fine, but none of the individuals were fined. Several of the employees said at the time they were told by the company solicitor not to give data to the regulator.Two years later, Southern was given a £90m fine after pleading guilty to thousands of illegal discharges of sewage over a five-year period.New rules coming into force on Friday will give legal agencies the power to bring prosecutions in the crown court against employees for obstructing regulatory investigations, with a maximum sanction of imprisonment.Directors and executives can be prosecuted if they have consented to or connived with that obstruction, or allowed it to happen through neglect.The rules were included in the Water (Special Measures) Act, which came into law in February. The act also gives the regulator new powers to ban bonuses if environmental standards are not met and requires companies to install real-time monitors at every emergency sewage outlet.Philip Duffy, the chief executive of the Environment Agency, said: “The act was a crucial step in making sure water companies take full responsibility for their impact on the environment.“The tougher powers we have gained through this legislation will allow us, as the regulator, to close the justice gap, deliver swifter enforcement action and ultimately deter illegal activity.“Alongside this, we’re modernising and expanding our approach to water company inspections – and it’s working. More people, powers, better data and inspections are yielding vital evidence so that we can reduce sewage pollution, hold water companies to account and protect the environment.”

Dead, sick pelicans turning up along Oregon coast

So far, no signs of bird flu but wildlife officials continue to test the birds.

Sick and dead pelicans are turning up on Oregon’s coast and state wildlife officials say they don’t yet know why. The Oregon Department of Fish and Wildlife says it has collected several dead brown pelican carcasses for testing. Lab results from two pelicans found in Newport have come back negative for highly pathogenic avian influenza, also known as bird flu, the agency said. Avian influenza was detected in Oregon last fall and earlier this year in both domestic animals and wildlife – but not brown pelicans. Additional test results are pending to determine if another disease or domoic acid toxicity caused by harmful algal blooms may be involved, officials said. In recent months, domoic acid toxicity has sickened or killed dozens of brown pelicans and numerous other wildlife in California. The sport harvest for razor clams is currently closed in Oregon – from Cascade Head to the California border – due to high levels of domoic acid detected last fall.Brown pelicans – easily recognized by their large size, massive bill and brownish plumage – breed in Southern California and migrate north along the Oregon coast in spring. Younger birds sometimes rest on the journey and may just be tired, not sick, officials said. If you find a sick, resting or dead pelican, leave it alone and keep dogs leashed and away from wildlife. State wildlife biologists along the coast are aware of the situation and the public doesn’t need to report sick, resting or dead pelicans. — Gosia Wozniacka covers environmental justice, climate change, the clean energy transition and other environmental issues.

Harris County commissioners approve climate justice plan

Nearly three years in the works, the Harris County Climate Justice Plan is a 59-page document that creates long-term strategies addressing natural resource conservation, infrastructure resiliency and flood control.

Sarah GrunauFlood waters fill southwest Houston streets during Hurricane Beryl on July 8, 2024.Harris County commissioners this month approved what’s considered the county’s most comprehensive climate justice plan to date. Nearly three years in the works, the Harris County Climate Justice Plan is a 59-page document that creates long-term strategies addressing natural resource conservation, infrastructure resiliency and flood control in the Houston area. The climate justice plan was created by the Office of County Administration’s Office of Sustainability and an environmental nonprofit, Coalition for Environment, Equity and Resilience. The plan sets goals in five buckets, said Stefania Tomaskovic, the coalition director for the nonprofit. Those include ecology, infrastructure, economy, community and culture. County officials got feedback from more than 340 residents and organizations to ensure the plans reflect the needs of the community. “We held a number of community meetings to really outline the vision and values for this process and then along the way we’ve integrated more and more community members into the process of helping to identify the major buckets of work,” Tomaskovic told Hello Houston. Feedback from those involved in the planning process of the climate justice plan had a simple message — people want clean air, strong infrastructure in their communities, transparency and the opportunity to live with dignity, according to the plan. It outlines plans to protect from certain risks through preventative floodplain and watershed management, land use regulations and proactive disaster preparation. Infrastructure steps in the plan include investing in generators and solar power battery backup, and expanding coordination of programs that provide rapid direct assistance after disasters. Economic steps in the plan including expanding resources with organizations to support programs that provide food, direct cash assistance and housing. Tomaskovic said the move could be cost effective because some studies show that for every dollar spent on mitigation, you’re actually saving $6. “It can be cost effective but also if you think about, like, the whole line of costs, if we are implementing programs that help keep people out of the emergency room, we could be saving in the long run, too,” she said. Funds that will go into implementing the projects have yet to be seen. The more than $700,000 climate plan was funded by nonprofit organizations, including the Jacob & Terese Hershey Foundation. “Some of them actually are just process improvements,” Lisa Lin, director of sustainability with Harris County, told Hello Houston. “Some of them are actually low-cost, no-cost actions. Some of them are kind of leaning on things that are happening in the community or happening in the county. Some of them might be new and then we’ll be looking at different funding sources.” The county will now be charged with bringing the plan into reality, which includes conducting a benefits and impacts analysis. County staffers will also develop an implementation roadmap to identify specific leaders and partners and a plan to track its success, according to the county. “This initiative is the first time a U.S. county has prepared a resiliency plan that covers its entire population, as opposed to its bureaucracy alone," Harris County Judge Lina Hidalgo said in a statement. "At the heart of this plan are realistic steps to advance issues like clean air, resilient infrastructure, and housing affordability and availability. Many portions of the plan are already in progress, and I look forward to continued advancement over the years."

50-Million-Year-Old Footprints Open a 'Rare Window' Into the Behaviors of Extinct Animals That Once Roamed in Oregon

Scientists revisited tracks made by a shorebird, a lizard, a cat-like predator and some sort of large herbivore at what is now John Day Fossil Beds National Monument

50-Million-Year-Old Footprints Open a ‘Rare Window’ Into the Behaviors of Extinct Animals That Once Roamed in Oregon Scientists revisited tracks made by a shorebird, a lizard, a cat-like predator and some sort of large herbivore at what is now John Day Fossil Beds National Monument Sarah Kuta - Daily Correspondent April 24, 2025 4:59 p.m. Researchers took a closer look at fossilized footprints—including these cat-like tracks—found at John Day Fossil Beds National Monument in Oregon. National Park Service Between 29 million and 50 million years ago, Oregon was teeming with life. Shorebirds searched for food in shallow water, lizards dashed along lake beds and saber-toothed predators prowled the landscape. Now, scientists are learning more about these prehistoric creatures by studying their fossilized footprints. They describe some of these tracks, discovered at John Day Fossil Beds National Monument, in a paper published earlier this year in the journal Palaeontologia Electronica. John Day Fossil Beds National Monument is a nearly 14,000-acre, federally protected area in central and eastern Oregon. It’s a well-known site for “body fossils,” like teeth and bones. But, more recently, paleontologists have been focusing their attention on “trace fossils”—indirect evidence of animals, like worm burrows, footprints, beak marks and impressions of claws. Both are useful for understanding the extinct creatures that once roamed the environment, though they provide different kinds of information about the past. “Body fossils tell us a lot about the structure of an organism, but a trace fossil … tells us a lot about behaviors,” says lead author Conner Bennett, an Earth and environmental scientist at Utah Tech University, to Crystal Ligori, host of Oregon Public Broadcasting’s “All Things Considered.” Oregon's prehistoric shorebirds probed for food the same way modern shorebirds do, according to the researchers. Bennett et al., Palaeontologia Electronica, 2025 For the study, scientists revisited fossilized footprints discovered at the national monument decades ago. Some specimens had sat in museum storage since the 1980s. They analyzed the tracks using a technique known as photogrammetry, which involved taking thousands of photographs to produce 3D models. These models allowed researchers to piece together some long-gone scenes. Small footprints and beak marks were discovered near invertebrate trails, suggesting that ancient shorebirds were pecking around in search of a meal between 39 million and 50 million years ago. This prehistoric behavior is “strikingly similar” to that of today’s shorebirds, according to a statement from the National Park Service. “It’s fascinating,” says Bennett in the statement. “That is an incredibly long time for a species to exhibit the same foraging patterns as its ancestors.” Photogrammetry techniques allowed the researchers to make 3D models of the tracks. Bennett et al., Palaeontologia Electronica, 2025 Researchers also analyzed a footprint with splayed toes and claws. This rare fossil was likely made by a running lizard around 50 million years ago, according to the team. It’s one of the few known reptile tracks in North America from that period.

A set of paw prints, discovered in a layer of volcanic ash, likely belonged to a bobcat-sized, saber-toothed predator resembling a cat—possibly a nimravid of the genus Hoplophoneus. Since researchers didn’t find any claw marks on the paw prints, they suspect the creature had retractable claws, just like modern cats do. A set of three-toed, rounded hoofprints indicate some sort of large herbivore was roaming around 29 million years ago, probably an ancient tapir or rhinoceros ancestor. Together, the fossil tracks open “a rare window into ancient ecosystems,” says study co-author Nicholas Famoso, paleontology program manager at the national monument, in the statement. “They add behavioral context to the body fossils we’ve collected over the years and help us better understand the climate and environmental conditions of prehistoric Oregon,” he adds.

Designing a new way to optimize complex coordinated systems

Using diagrams to represent interactions in multipart systems can provide a faster way to design software improvements.

Coordinating complicated interactive systems, whether it’s the different modes of transportation in a city or the various components that must work together to make an effective and efficient robot, is an increasingly important subject for software designers to tackle. Now, researchers at MIT have developed an entirely new way of approaching these complex problems, using simple diagrams as a tool to reveal better approaches to software optimization in deep-learning models.They say the new method makes addressing these complex tasks so simple that it can be reduced to a drawing that would fit on the back of a napkin.The new approach is described in the journal Transactions of Machine Learning Research, in a paper by incoming doctoral student Vincent Abbott and Professor Gioele Zardini of MIT’s Laboratory for Information and Decision Systems (LIDS).“We designed a new language to talk about these new systems,” Zardini says. This new diagram-based “language” is heavily based on something called category theory, he explains.It all has to do with designing the underlying architecture of computer algorithms — the programs that will actually end up sensing and controlling the various different parts of the system that’s being optimized. “The components are different pieces of an algorithm, and they have to talk to each other, exchange information, but also account for energy usage, memory consumption, and so on.” Such optimizations are notoriously difficult because each change in one part of the system can in turn cause changes in other parts, which can further affect other parts, and so on.The researchers decided to focus on the particular class of deep-learning algorithms, which are currently a hot topic of research. Deep learning is the basis of the large artificial intelligence models, including large language models such as ChatGPT and image-generation models such as Midjourney. These models manipulate data by a “deep” series of matrix multiplications interspersed with other operations. The numbers within matrices are parameters, and are updated during long training runs, allowing for complex patterns to be found. Models consist of billions of parameters, making computation expensive, and hence improved resource usage and optimization invaluable.Diagrams can represent details of the parallelized operations that deep-learning models consist of, revealing the relationships between algorithms and the parallelized graphics processing unit (GPU) hardware they run on, supplied by companies such as NVIDIA. “I’m very excited about this,” says Zardini, because “we seem to have found a language that very nicely describes deep learning algorithms, explicitly representing all the important things, which is the operators you use,” for example the energy consumption, the memory allocation, and any other parameter that you’re trying to optimize for.Much of the progress within deep learning has stemmed from resource efficiency optimizations. The latest DeepSeek model showed that a small team can compete with top models from OpenAI and other major labs by focusing on resource efficiency and the relationship between software and hardware. Typically, in deriving these optimizations, he says, “people need a lot of trial and error to discover new architectures.” For example, a widely used optimization program called FlashAttention took more than four years to develop, he says. But with the new framework they developed, “we can really approach this problem in a more formal way.” And all of this is represented visually in a precisely defined graphical language.But the methods that have been used to find these improvements “are very limited,” he says. “I think this shows that there’s a major gap, in that we don’t have a formal systematic method of relating an algorithm to either its optimal execution, or even really understanding how many resources it will take to run.” But now, with the new diagram-based method they devised, such a system exists.Category theory, which underlies this approach, is a way of mathematically describing the different components of a system and how they interact in a generalized, abstract manner. Different perspectives can be related. For example, mathematical formulas can be related to algorithms that implement them and use resources, or descriptions of systems can be related to robust “monoidal string diagrams.” These visualizations allow you to directly play around and experiment with how the different parts connect and interact. What they developed, he says, amounts to “string diagrams on steroids,” which incorporates many more graphical conventions and many more properties.“Category theory can be thought of as the mathematics of abstraction and composition,” Abbott says. “Any compositional system can be described using category theory, and the relationship between compositional systems can then also be studied.” Algebraic rules that are typically associated with functions can also be represented as diagrams, he says. “Then, a lot of the visual tricks we can do with diagrams, we can relate to algebraic tricks and functions. So, it creates this correspondence between these different systems.”As a result, he says, “this solves a very important problem, which is that we have these deep-learning algorithms, but they’re not clearly understood as mathematical models.” But by representing them as diagrams, it becomes possible to approach them formally and systematically, he says.One thing this enables is a clear visual understanding of the way parallel real-world processes can be represented by parallel processing in multicore computer GPUs. “In this way,” Abbott says, “diagrams can both represent a function, and then reveal how to optimally execute it on a GPU.”The “attention” algorithm is used by deep-learning algorithms that require general, contextual information, and is a key phase of the serialized blocks that constitute large language models such as ChatGPT. FlashAttention is an optimization that took years to develop, but resulted in a sixfold improvement in the speed of attention algorithms.Applying their method to the well-established FlashAttention algorithm, Zardini says that “here we are able to derive it, literally, on a napkin.” He then adds, “OK, maybe it’s a large napkin.” But to drive home the point about how much their new approach can simplify dealing with these complex algorithms, they titled their formal research paper on the work “FlashAttention on a Napkin.”This method, Abbott says, “allows for optimization to be really quickly derived, in contrast to prevailing methods.” While they initially applied this approach to the already existing FlashAttention algorithm, thus verifying its effectiveness, “we hope to now use this language to automate the detection of improvements,” says Zardini, who in addition to being a principal investigator in LIDS, is the Rudge and Nancy Allen Assistant Professor of Civil and Environmental Engineering, and an affiliate faculty with the Institute for Data, Systems, and Society.The plan is that ultimately, he says, they will develop the software to the point that “the researcher uploads their code, and with the new algorithm you automatically detect what can be improved, what can be optimized, and you return an optimized version of the algorithm to the user.”In addition to automating algorithm optimization, Zardini notes that a robust analysis of how deep-learning algorithms relate to hardware resource usage allows for systematic co-design of hardware and software. This line of work integrates with Zardini’s focus on categorical co-design, which uses the tools of category theory to simultaneously optimize various components of engineered systems.Abbott says that “this whole field of optimized deep learning models, I believe, is quite critically unaddressed, and that’s why these diagrams are so exciting. They open the doors to a systematic approach to this problem.”“I’m very impressed by the quality of this research. ... The new approach to diagramming deep-learning algorithms used by this paper could be a very significant step,” says Jeremy Howard, founder and CEO of Answers.ai, who was not associated with this work. “This paper is the first time I’ve seen such a notation used to deeply analyze the performance of a deep-learning algorithm on real-world hardware. ... The next step will be to see whether real-world performance gains can be achieved.”“This is a beautifully executed piece of theoretical research, which also aims for high accessibility to uninitiated readers — a trait rarely seen in papers of this kind,” says Petar Velickovic, a senior research scientist at Google DeepMind and a lecturer at Cambridge University, who was not associated with this work. These researchers, he says, “are clearly excellent communicators, and I cannot wait to see what they come up with next!”The new diagram-based language, having been posted online, has already attracted great attention and interest from software developers. A reviewer from Abbott’s prior paper introducing the diagrams noted that “The proposed neural circuit diagrams look great from an artistic standpoint (as far as I am able to judge this).” “It’s technical research, but it’s also flashy!” Zardini says.
