Mass Layoffs Overshadow Guinea's Simandou Mega Mine as Output Accelerates

By Clara Denina and Maxwell Akalaare AdombilaSIMANDOU, Guinea, Dec 18 (Reuters) - Guinea's Simandou mega mining project, promoted by the military government as a symbol of the country's economic transformation, ‌is laying ​off thousands of workers just as it begins exporting iron ore after decades of delays ‌and corruption scandals.Simandou was officially launched with pomp and a public holiday in November, ahead of elections on December 28, the first since the military coup in 2021 that brought Mamady Doumbouya to power.The junta leader is standing ​for president and political analysts say he is the favourite to win, meaning he could be in power for another seven years.Even without Simandou, the world's largest untapped reserve of iron ore, Guinea is the world's biggest exporter of bauxite, used to make aluminium. Its mining wealth, however, has failed to transform for the better the lives of many of ‍its people.World Bank data published in 2025 showed more than half the population lived ​in poverty.Reuters interviewed a dozen workers and former employees, as well as some senior company sources. Asking not to be named because of the sensitivity of the issue, they said the process of sacking thousands of workers had begun and that the impact was likely to be more severe than in the case of comparable mining projects.It is a bitter ​disappointment for those who hoped their lives ⁠would be improved for the long term by Simandou's ambitions to produce around 120 million metric tons of iron ore annually, or around 7% of global demand.EMPLOYMENT PEAKED AT MORE THAN 60,000Employment from Simandou peaked at over 60,000 jobs in 2024 and 2025, companies and government sources told Reuters, as contractors raced to meet deadlines set by Guinea's military rulers to try to fast-track iron ore exports after nearly three decades of delay. Fewer than 15,000 people will be needed to run the mines, the ports, and the 670 kilometre (416-mile) railway specially built to allow export from the landlocked project.The project is run by two consortia – one led by Rio Tinto and the other by the Winning Consortium Simandou, or WCS, comprising mostly Chinese companies. The way the work has been organised means the workforce reduction is extreme.One executive involved said the railway was "a simultaneous spread project," meaning every section was built at the same time, the labour ‌force was ramped up to peak construction, "then falls off a cliff because everything finishes".WCS, which manages almost all of the railway via more than a dozen subcontractors, did not respond to requests for comment on its workforce.Rio Tinto, through a joint venture Rio Tinto-Simfer, is in charge of ​two ‌mine blocks, 78 kilometres of rail connecting them to the main ‍rail network and transshipment facilities at the new port on Guinea's Atlantic coast. ⁠In all, it has provided employment for around 25,000 workers, 82% of them Guinean, over the construction phase.For the operational phase, a spokesperson for Rio Tinto said the Simfer venture was expected to require a workforce of about 6,000 to work in the mine and at a transshipment vessel terminal at the port. The mine and rail construction is scheduled to be completed next year, while work at the port will continue through 2027, the spokesperson said.Chris Aitchison, managing director at Rio Tinto-Simfer, said he was concerned about the risks raised by sudden job losses, which the industry refers to as demobilisation."It's the what's next?" he said. "In other jurisdictions when we demobilise there's a pathway for employees or people that have been engaged in execution to move to other projects."In comparable projects, such as Mongolia's Oyu Tolgoi copper mine, for example, more diversified economies meant former mining employees had other job options.RISK OF SOCIAL UNREST AND ACCIDENTSThe workforce sources said the job-cutting had begun. In Dantilia, a hub in the Faranah region near Sierra Leone's border, 8,000 of 10,000 workers have lost their jobs the last three months. The other 2,000 have been told their jobs will end in the coming months. In Kamara, part of the same district, around 1,500 workers have already been dismissed, the workers said.   "We are waiting in hope but for now they don't have any solutions, and they haven't promised anything yet," a pick-up ​driver for the Winning Consortium Simandou told Reuters, asking not to be named. "There is no other job."Three Western company sources said concern was mounting that reduced staffing could increase the risk of accidents, as well as of social unrest. They said they were worried about the likelihood of community protests that could take the form of blockades along the Simandou railway, where trains have already killed cattle, angering local residents who depend on their livestock.Risk assessments carried out by the consortia in the last six months flagged the places where people or livestock could stray onto tracks and derail trains, prompting the construction of fencing that the original design did not provide for, company sources said.In March, Reuters reported that a dozen workers had died in accidents during Simandou's railway construction between June 2023 and November 2024. In addition, at least five local residents were killed in traffic accidents involving vehicles from the works.Rio Tinto and WCS reported a further five worker deaths. Mines minister Bouna Sylla said the government was strict with the partners on safety and environmental safeguards.GOVERNMENT'S PROMISES OF FUTURE EMPLOYMENTGuinea's limited infrastructure, narrow skill base, and lack of income buffers magnify the impact of the sudden loss of jobs.Speaking to media in the days ahead of Simandou's official launch on November 11, Sylla acknowledged the layoffs would be painful."It's not easy for people who've been earning a salary, waking up early for work every day, to suddenly lose it," Sylla said. He outlined government plans for new infrastructure projects, including roads, refineries and power plants, but he did not give any timing.The official launch at the new export port at Morebaya on Guinea's Atlantic coast was resolutely upbeat, with brass bands, honour guards, traditional dancers and visiting dignitaries. Doumbouya looked on, dressed in a white Guinean boubou tunic.In an attempt to provide thousands of future jobs, Guinea's military government has touted "Simandou 2040" as a 15-year strategy to transform the country into a diversified economy, based on investment in agriculture, education, transport, technology, ​finance and health for the entire population.The government holds a 15% stake in Simandou and the plan's estimated $200 billion cost would be partly funded by mining revenues, although it has said the bulk should come from private capital.Sylla said Guinea's infrastructure agency the Administration et Contrôle des Grands Projets was working on feasibility studies. The government also commissioned a KPMG report on re-employment programmes, which will be published after the elections, two sources said.KPMG did not respond to a request for comment. The infrastructure agency said the plans included 3,000 kilometres of new highways to be developed over 15 years.THE LONG WAIT FOR PROSPERITYBut nearly 30 years after Rio started exploring the deposit, the question of whether Simandou can deliver prosperity for most of Guinea is unanswered.The IMF in its "Selected issues" paper on Guinea's economy, published in May  2024, modelled the macroeconomic effects of Simandou.It ​found it could boost the country's real GDP by 26% by 2030, but it also said the reduction in poverty could be minimal at just 0.6 percentage points without active policies to manage the transition.The project's impact in increasing the number of skilled workers could even lead "to worsening of inequality, especially in rural areas," it said.(Reporting by Clara Denina and Maxwell Adombila Akalaare; editing by Barbara Lewis)Copyright 2025 Thomson Reuters.Photos You Should See – December 2025

Don’t talk – listen. Why communities affected by forever chemicals in water must be heard

When worried communities talk to authorities about forever chemicals, officials often seek to explain and clarify. But this isn’t what people actually want.

97s/Unsplash, CC BY-NC-NDUntil recently, Australia’s efforts to tackle “forever chemical” pollution focused on highly polluted firefighting and defence sites. But last year, elevated levels of some of these chemicals were detected in the untreated water supply for the Blue Mountains in New South Wales. Residents were understandably concerned. Community groups threatened to launch a class action, while residents sought to have their blood tested. NSW Water Minister Rose Jackson moved to reassure residents their “water is safe”, and a Sydney Morning Herald editorial said the state government was blind to the risks. Earlier this year, Australia banned three of these chemicals – PFOA, PFOS and PFHxS. PFOA is considered carcinogenic by the International Agency for Research on Cancer, while PFOS is considered possibly carcinogenic. But the environmental and health effects of forever chemical exposure remain a matter of debate, as the risk depends on concentration. In November, a Senate inquiry made dozens of recommendations to better regulate these chemicals. All too often, authorities respond to legitimate community concerns by pointing to the low level of risk. But as these chemicals build up in drinking water, wastewater and farming soils, this trust-the-experts approach isn’t going to work. Risks and concentration levels Forever chemicals are properly known as PFAS (per- and polyfluoroalkyl substances). They’re used in products such as carpets, clothes, food packaging and paper, as well as firefighting foams, pesticides and stain repellents. They don’t break down easily, and steadily accumulate in soil, surface water and groundwater. Around 15,000 PFAS chemicals are now ubiquitous in the environment. In highly contaminated sites such as firefighter training facilities or defence bases, the risk is clearer and responses can target specific facilities and geographic locations. But the question of what to do becomes much harder when forever chemicals become widely distributed in drinking water and wastewater systems, generally at levels well below thresholds considered dangerous according to Australian standards. In response to the Blue Mountains issue, Water NSW stopped two dams from supplying water as a precautionary measure. Sydney Water installed a new PFAS water treatment system. Community backlash Australian authorities began responding to PFAS contamination a decade ago. Since then, policymakers have restricted the import and manufacture of certain forever chemicals, banned some uses of PFAS-containing firefighting foams, developed a national plan to manage PFAS chemicals, officially set the levels of PFAS a person could safely consume in a day and developed guidelines for drinking water. Even with such actions, authorities have been subject to sustained public criticism from community groups and the media over the speed, adequacy and level of protections compared to the more restrictive thresholds set by the United States and European Union. At Williamtown in NSW, authorities were aware of the issue for three years before revealing it. Community groups lost faith in official responses, turning to external experts before ultimately launching a class action against the Department of Defence. Some compensation flowed from this based on financial losses. But researchers have found compensation does little to actually address residents’ health and environment concerns. Independent reviews have recommended official responses to PFAS should be more transparent. But little has changed. The same distrust is emerging in the Blue Mountains, while state and federal inquiries have raised questions over how PFAS risks are communicated and falling public trust in government agencies. Better communication misses the point Community backlash against issues such as PFAS contamination can often be framed as non-experts misunderstanding the science. Authorities often think the answer is to communicate better and more clearly to fix the deficit. For instance, the national PFAS policy describes communication as essential: if people affected by PFAS contamination cannot understand what governments are saying, they are more likely to view the information with scepticism or as a deliberate attempt to disguise the facts. The risk here is that focusing on better official communication is still about speaking, rather than listening. The community can become a noisy stakeholder to be managed rather than an active collaborator. But people in these communities are legitimately worried. They want to speak and be heard as equal partners. Is there a better way? PFAS contamination isn’t just a technological or legal issue. It’s also a social issue – it affects communities. When facing a pollution problem, affected communities often organise themselves and advocate for better outcomes. Community groups often commission independent research or conduct citizen science, while collaborating with scientists and engineers. Officials and residents should collectively work through the options and costs associated, as well as discussing what level of risk different communities are willing to accept. Public forums aren’t enough, as these tend to put experts at the centre, answering questions. The launch of the first community-based PFAS working group under the new PFAS National Coordinating Body is a positive initial step. Collaborative efforts like this are not easy. Authorities and community leaders can view each other with suspicion, and the unequal power dynamics play a role. As NSW Information Commissioner Rosalind Croucher recently pointed out, making contamination data easily available to communities helps ensure management is “transparent, evidence-based, and accountable to the communities it affects”. Hard but not impossible Like forever chemicals themselves, the issue of PFAS pollution isn’t going away. Finding better ways of responding will be essential, as the issue can’t be solved by scientists, engineers and policymakers in a top-down approach. Communities who have to drink the water must be given the right to speak – and be heard. Read more: Living with PFAS 'forever chemicals' can be distressing.

Unreliable Data Mask Just How Bad the Air Quality Crisis Is in India

India’s air-quality crisis is deepened by unreliable data

NEW DELHI (AP) — Recent remarks about pollution from two Indian officials have increased frustration among residents who say policymakers are unwilling to acknowledge the severity of India's air quality crisis. When Environment Minister Bhupender Yadav told Parliament earlier this month that India’s capital, New Delhi, has seen 200 days with good air quality readings, pollution experts and opposition leaders said he chose a figure that overlooked the worst pollution months. A week later, Delhi Chief Minister Rekha Gupta said the air quality index — a measure of air pollution — was similar to a temperature reading and could be dealt with by spraying water. Crowds jeered her at a subsequent public event, shouting “AQI” in reference to the city's poor air quality readings. Gupta had also greenlit a controversial cloud seeding program earlier this year, saying it could produce rain that would lower pollution — despite lack of evidence that the approach would work.“Instead of doing cloud seeding, I hope the government will wake up and take some real action,” said Anita, a 73-year-old New Delhi resident who goes by only one name. “It’s a shame."Environmentalists and data experts said India’s air quality measurement standards are looser than in countries such as the United States, so moderate readings often mask dangerous pollution levels. India's government air quality standards are also less stringent than World Health Organization guidelines.Experts said these gaps can erode public trust, even as few residents fully grasp how harmful polluted air is. Gaps in India’s air quality data India’s air quality is measured through a nationwide network of monitors and sensors, as well as satellite data. The monitors collect robust data, but there are too few of them, said Ronak Sutaria, CEO of Respirer Living, which builds machines and software for air quality monitoring. He said that the system falls short of letting citizens know how polluted the air in their neighborhoods really is. In 2019, India launched the National Clean Air Program, which set targets aiming to reduce pollution by up to 40% in 131 cities by 2026.The program has seen relative success, providing millions of dollars for monitors and water-spraying machines to reduce dust generated from vehicles plying the roads, construction activity and winds that blow desert sand into the cities. However, air pollution experts said the program has done little to reduce pollution from carbon-spewing industries or vehicle emissions, which are among the biggest sources of dirty air. Other sources include the burning of crop stubble on farms, use of wood and cow dung as cooking fuel and burning of garbage.A 2024 report by the Centre for Science and Environment, a New Delhi-based think tank, found that 64% of funds under the program went toward reducing dust and only 12% to reducing pollution from vehicles and less than 1% to bringing down industrial air pollution.“We are making huge investments in air quality monitoring. And so when we are expanding, then it also becomes an imperative that we should be focusing on the quality,” said Anumita Roychowdhury, executive director at the think tank. A public health emergency A study last year by the medical journal Lancet linked long-term exposure to polluted air to 1.5 million additional deaths every year in India, compared to a scenario where the country would have met WHO standards.Yet earlier this month, Prataprao Jadhav, India’s junior health minister, said there is no conclusive data available in the country to establish a direct correlation of death or disease exclusively to air pollution.Shweta Narayan, a campaign lead at the Global Climate and Health Alliance, said that air pollution is still not taken seriously as a public health issue.“Deaths related to air pollution are not being counted. And the reason why it’s not being counted is because there are no systematic mechanisms to do so,” Narayan said.Narayan said pollution causes long-term health problems for everyone exposed, but that it's especially bad for pregnant women, the elderly and children. “As a consequence of exposure to air pollution, we see a lot of preterm births, miscarriages, low birth weight. Exposure at this stage has a lifelong consequence,” she said.Earlier this month, New Delhi residents took to the streets to protest against dirty air and demand immediate government action in a relatively rare instance of public demonstrations. “We do not know whether ... citizens will be able to link air pollution to elections, but perhaps that’s where India is moving toward,” environmentalist Vimlendu Jha said in an interview. “Citizens are fed up.”Jha said authorities are not being honest about the problem and that there is a lack of political will to address the issue. “There’s more headline and image management than pollution management,” he said, adding that the high levels of pollution have been treated as normal by political leaders. “The first thing that the government needs to do is to be honest about the problem that we have," he said. "The right diagnosis is extremely critical.” Regardless of whether policymakers act, the consequences of dirty air for the residents of India’s capital are evident. “Everyone feels the pollution. People are not able to work or even breathe,” said Satish Sharma, a 60-year-old auto rickshaw driver. Sharma said he has reduced his work hours as his health has deteriorated in the last few weeks because of the pollution. “I want to tell the government to please do something about this pollution," he said. "Otherwise, people will move away from here.”Arasu reported from Bengaluru, India.

Trump admin orders Washington state coal plant to stay running

The Trump administration has ordered another aging, costly coal plant to keep operating past its long-planned retirement date — this time in Centralia, Washington. On Tuesday, the U.S. Department of Energy issued an emergency order requiring Unit 2 of the TransAlta Centralia Generation power plant to keep running…

“As families struggle with rising electricity bills, the Trump Administration is delivering coal for Christmas and forcing households to pay for it,” Earthjustice attorney Michael Lenoff, who is leading litigation against the DOE on its J.H. Campbell plant stay-open order, said in a Wednesday statement after the Centralia must-run order was issued. ​“Coal is not only the most polluting and carbon-intensive source of electricity, it’s expensive. And these aging coal plants are increasingly unreliable.”  DOE’s must-run order for TransAlta’s Unit 2 may also complicate plans to convert the power plant to run on fossil gas. Less than a week ago, TransAlta announced an agreement with utility Puget Sound Energy to convert Unit 2 to gas by late 2028 at a cost of about $600 million, which the firm said would help meet regional grid needs while reducing carbon emissions. Pacific Northwest utilities in September released a report expressing concerns about longer-running grid reliability challenges in the region. Tuesday’s DOE order cited a separate analysis from the North American Electric Reliability Corporation (NERC) indicating ​“elevated risk during periods of extreme weather” for the Northwest region as justification for keeping the Centralia plant running.  But critics have pointed out that DOE’s Section 202(c) authority to force power plants to keep running for up to 90 days at a time is meant to deal with immediate emergencies, rather than serve as a tool to override the long-term planning and analysis of utilities, state regulators, regional grid operators, and reliability coordinators.  And if you’re aiming to boost reliability, aging coal plants are not your best bet. They are more likely to experience unplanned outages than modern power plants, according to a recent analysis of NERC data conducted by the Environmental Defense Fund.  “There is no ​‘energy emergency’ in the Pacific Northwest that would justify forcing the continued operation of an old and dirty coal plant,” Ben Avery, the Sierra Club’s Washington state director, said in a statement on Wednesday. ​“All the evidence shows that when Centralia shuts down, customers’ costs will decrease and air quality will improve. Instead of lowering bills or protecting families from harmful pollution, the Trump administration is abusing emergency powers to prop up fossil fuels at any cost.” { if ($event.target.classList.contains('hs-richtext')) { if ($event.target.textContent === '+ more options') { $event.target.remove(); open = true; } } }" >

What’s Next for NV Energy’s Greenlink After Feds Reject Initial Environmental Analysis?

In a rare move that could delay progress on NV Energy’s large-scale transmission line planned for the Highway 50 corridor, the federal Bureau of Land Management has ordered its Nevada office to address some environmental groups’ protests against the project

In a rare move that could delay progress on NV Energy’s large-scale transmission line planned for the Highway 50 corridor, the federal Bureau of Land Management has ordered its Nevada office to address some environmental groups’ protests against the project.In May, the BLM’s Nevada State Office released its environmental report for the Greenlink North project, as well as a proposed amendment to the resource management plan for the area. Various conservation and wildlife groups and Lander County immediately filed three administrative objections to the report, which needs to be finalized before construction can begin on the multibillion dollar project. Protesters raised nine issues, and last month, the federal BLM sided with them on four.“All of the protest letters contained a valid protest issue,” according to the federal BLM.The federal agency remanded the protest areas back to Nevada State BLM Director John Raby “for consideration, clarification, further planning, or other appropriate action to resolve this protest issue.”The protests include how the project would affect greater sage-grouse populations, a species in a sharp decline that has flirted with a listing on the federal endangered species list. Currently, under certain conditions, high-voltage transmission lines must be excluded from critical sage-grouse habitat areas; the project is proposed to cut through 162 miles of critical habitat. “Instead of conforming to the existing resource management plans across central Nevada, BLM is pushing to amend plans and ram this huge transmission project through important sage-grouse areas,” according to Laura Cunningham, California director of Western Watersheds Project.The decision by the federal BLM to side with the protesters is rare, said Kevin Emmerich, co-founder of conservation group Basin and Range Watch. Emmerich estimates he has filed more than 50 protests with the bureau, but this is the first to succeed.Greenlink North is a proposed 525 kilovolt transmission line slated to span from Ely to near Yerington, including the construction of two new substations. It would run along Highway 50, one of the most remote and undeveloped areas in the nation.The area is “one of the most unspoiled and stunning regions of the Great Basin,” Emmerich said. The project is one piece of a three-prong transmission line that will span the state. At completion, it would connect to the still-under-construction Greenlink West, running from Reno to Las Vegas, and the One Nevada transmission line, which runs from Ely to Las Vegas.Greenlink West, which is under construction, is expected to be in service by May 2027. Construction of Greenlink North is slated to begin in January 2027, with the line in service by late 2028. A final record of decision on the project was originally slated to be issued in October; now, the state BLM will need to draft a supplemental environmental impact statement. Patrick Donnelly, Great Basin director for the Center for Biological Diversity, told The Nevada Independent that the process could take months. “This is a major delay,” he said.NV Energy spokesperson Meghin Delaney said in an email that project approval and permits are on schedule to be completed before the 2027 construction date. “Our team is monitoring the process closely and will make any necessary adjustments to meet the project’s in-service date without sacrificing safety or quality,” Delaney wrote. Sage-grouse protections and visual effects at issue While Greenlink started as a project to align with 2019 legislation calling for the construction of a high-powered transmission line in the state, it has grown into a sprawling utility corridor — more than 100,000 acres of solar and wind energy applications have been submitted along the Greenlink North route.Protesters argued that the combination of the transmission line and ensuing energy development around the corridor will harm the region’s imperiled greater sage-grouse, as well as damage the scenic nature of the region. The four areas in which the feds agreed with the protesters are:1. Visual resources: Protesters argued the state BLM violated the Federal Land Policy and Management Act by failing to consider the project’s effects on the area’s visual resources. The agency does not have regulations covering the management of visual resources on public lands; instead, the agency uses internal guidance. “We have been asking the BLM to be in better compliance with their own visual resource management guidelines for 15 years,” Emmerich told The Indy. “This is the first time they actually listened in Nevada.”2. Avoidable degradation: Protesters argued that the “BLM failed to examine in detail any alternative that would meaningfully reduce impacts to greater sage-grouse.” The feds agreed, stating that the existing Greenlink North documents do “not offer an explanation of whether the proposed … amendments to greater sage-grouse management will cause unnecessary or undue degradation.” 3. Conformance to planning regulations: Protesters claimed that Greenlink North’s existing environmental documents do not conform with the underlying land use plans, including guiding documents for management of greater sage-grouse. 4. Failure to consider alternatives: The groups claim that the state BLM violated the National Environmental Policy Act by failing to consider a reasonable range of alternatives, including taking a different route than the one proposed by NV Energy, as well as changes to seasonal restrictions on sage-grouse winter range. “Not far to the north, a rail line and Interstate 80 already traverse this east-west route with major disturbances that would absorb a transmission line seemingly unnoticed to wildlife,” representatives of Lander County wrote. “The failure to prioritize such alternatives in the planning process reflects inadequate consideration of less harmful options.”This story was originally published by The Nevada Independent and distributed through a partnership with The Associated Press.Copyright 2025 The Associated Press.

A “scientific sandbox” lets researchers explore the evolution of vision systems

The AI-powered tool could inform the design of better sensors and cameras for robots or autonomous vehicles.

Why did humans evolve the eyes we have today?While scientists can’t go back in time to study the environmental pressures that shaped the evolution of the diverse vision systems that exist in nature, a new computational framework developed by MIT researchers allows them to explore this evolution in artificial intelligence agents.The framework they developed, in which embodied AI agents evolve eyes and learn to see over many generations, is like a “scientific sandbox” that allows researchers to recreate different evolutionary trees. The user does this by changing the structure of the world and the tasks AI agents complete, such as finding food or telling objects apart.This allows them to study why one animal may have evolved simple, light-sensitive patches as eyes, while another has complex, camera-type eyes.The researchers’ experiments with this framework showcase how tasks drove eye evolution in the agents. For instance, they found that navigation tasks often led to the evolution of compound eyes with many individual units, like the eyes of insects and crustaceans.On the other hand, if agents focused on object discrimination, they were more likely to evolve camera-type eyes with irises and retinas.This framework could enable scientists to probe “what-if” questions about vision systems that are difficult to study experimentally. It could also guide the design of novel sensors and cameras for robots, drones, and wearable devices that balance performance with real-world constraints like energy efficiency and manufacturability.“While we can never go back and figure out every detail of how evolution took place, in this work we’ve created an environment where we can, in a sense, recreate evolution and probe the environment in all these different ways. This method of doing science opens to the door to a lot of possibilities,” says Kushagra Tiwary, a graduate student at the MIT Media Lab and co-lead author of a paper on this research.He is joined on the paper by co-lead author and fellow graduate student Aaron Young; graduate student Tzofi Klinghoffer; former postdoc Akshat Dave, who is now an assistant professor at Stony Brook University; Tomaso Poggio, the Eugene McDermott Professor in the Department of Brain and Cognitive Sciences, an investigator in the McGovern Institute, and co-director of the Center for Brains, Minds, and Machines; co-senior authors Brian Cheung, a postdoc in the  Center for Brains, Minds, and Machines and an incoming assistant professor at the University of California San Francisco; and Ramesh Raskar, associate professor of media arts and sciences and leader of the Camera Culture Group at MIT; as well as others at Rice University and Lund University. The research appears today in Science Advances.Building a scientific sandboxThe paper began as a conversation among the researchers about discovering new vision systems that could be useful in different fields, like robotics. To test their “what-if” questions, the researchers decided to use AI to explore the many evolutionary possibilities.“What-if questions inspired me when I was growing up to study science. With AI, we have a unique opportunity to create these embodied agents that allow us to ask the kinds of questions that would usually be impossible to answer,” Tiwary says.To build this evolutionary sandbox, the researchers took all the elements of a camera, like the sensors, lenses, apertures, and processors, and converted them into parameters that an embodied AI agent could learn.They used those building blocks as the starting point for an algorithmic learning mechanism an agent would use as it evolved eyes over time.“We couldn’t simulate the entire universe atom-by-atom. It was challenging to determine which ingredients we needed, which ingredients we didn’t need, and how to allocate resources over those different elements,” Cheung says.In their framework, this evolutionary algorithm can choose which elements to evolve based on the constraints of the environment and the task of the agent.Each environment has a single task, such as navigation, food identification, or prey tracking, designed to mimic real visual tasks animals must overcome to survive. The agents start with a single photoreceptor that looks out at the world and an associated neural network model that processes visual information.Then, over each agent’s lifetime, it is trained using reinforcement learning, a trial-and-error technique where the agent is rewarded for accomplishing the goal of its task. The environment also incorporates constraints, like a certain number of pixels for an agent’s visual sensors.“These constraints drive the design process, the same way we have physical constraints in our world, like the physics of light, that have driven the design of our own eyes,” Tiwary says.Over many generations, agents evolve different elements of vision systems that maximize rewards.Their framework uses a genetic encoding mechanism to computationally mimic evolution, where individual genes mutate to control an agent’s development.For instance, morphological genes capture how the agent views the environment and control eye placement; optical genes determine how the eye interacts with light and dictate the number of photoreceptors; and neural genes control the learning capacity of the agents.Testing hypothesesWhen the researchers set up experiments in this framework, they found that tasks had a major influence on the vision systems the agents evolved.For instance, agents that were focused on navigation tasks developed eyes designed to maximize spatial awareness through low-resolution sensing, while agents tasked with detecting objects developed eyes focused more on frontal acuity, rather than peripheral vision.Another experiment indicated that a bigger brain isn’t always better when it comes to processing visual information. Only so much visual information can go into the system at a time, based on physical constraints like the number of photoreceptors in the eyes.“At some point a bigger brain doesn’t help the agents at all, and in nature that would be a waste of resources,” Cheung says.In the future, the researchers want to use this simulator to explore the best vision systems for specific applications, which could help scientists develop task-specific sensors and cameras. They also want to integrate LLMs into their framework to make it easier for users to ask “what-if” questions and study additional possibilities.“There’s a real benefit that comes from asking questions in a more imaginative way. I hope this inspires others to create larger frameworks, where instead of focusing on narrow questions that cover a specific area, they are looking to answer questions with a much wider scope,” Cheung says.This work was supported, in part, by the Center for Brains, Minds, and Machines and the Defense Advanced Research Projects Agency (DARPA) Mathematics for the Discovery of Algorithms and Architectures (DIAL) program.

TUNIS, Dec 17 (Reuters) - Around 2,500 ‌Tunisians ​marched through the coastal city ‌of Gabes on Wednesday, reviving protests over pollution from a ​state-owned phosphate complex amid rising anger over perceived failures to protect public health.People chanted ‍mainly "Gabes wants to live", on ​the 15th anniversary of the start of the 2011 pro-democracy uprising that sparked ​the Arab ⁠Spring movement against autocracy.The protest added to the pressure on President Kais Saied’s government, which is grappling with a deep financial crisis and growing street unrest, protests by doctors, journalists, banks and public transport systems. The powerful UGTT union has called ‌for a nationwide strike next month, signalling great tension in the country. The ​recent ‌protests are widely seen ‍as one ⁠of the biggest challenges facing Saied since he began ruling by decree in 2021.Protesters chanted slogans such as "We want to live" and "People want to dismantle polluting units", as they marched toward Chatt Essalam, a coastal suburb north of the city where the Chemical Group’s industrial units are located."The chemical plant is a fully fledged crime... We refuse to ​pass on an environmental disaster to our children, and we are determined to stick to our demand,” said Safouan Kbibieh, a local environmental activist.Residents say toxic emissions from the phosphate complex have led to higher rates of respiratory illnesses, osteoporosis and cancer, while industrial waste continues to be discharged into the sea, damaging marine life and livelihoods.The protests in Gabes were reignited after hundreds of schoolchildren suffered breathing difficulties in recent months, allegedly caused by toxic fumes from a plant converting phosphates into phosphoric ​acid and fertilisers.In October, Saied described the situation in Gabes as an “environmental assassination”, blaming policy choices made by previous governments, and has called for urgent maintenance to prevent toxic leaks.The protesters reject the temporary measures and ​are demanding the permanent closure and relocation of the plant.(Reporting by Tarek Amara, editing by Ed Osmond)Copyright 2025 Thomson Reuters.Photos You Should See – December 2025

‘Everything is worse since Drax came here’: US residents say wood-pellet plant harming their town

Residents of Gloster, Mississippi, are suing plant that exports wood pellets to UK and Europe. Company says it is reducing emissionsWhen Helen Reed first learned about the bioenergy mill opening in her hometown of Gloster, Mississippi, the word was it would bring jobs and economic opportunities. It was only later that she learned that activity came with a cost: the Amite Bioenergy mill, opened in 2014 by British energy giant Drax, emits large – and sometimes illegal – quantities of air pollutants, including methanol, acrolein and formaldehyde, which are linked to cancers and other serious illnesses.“When I go out, I can’t hardly catch my breath,” Reed said. “Everything is worse since Drax came here.” Continue reading...

When Helen Reed first learned about the bioenergy mill opening in her hometown of Gloster, Mississippi, the word was it would bring jobs and economic opportunities. It was only later that she learned that activity came with a cost: the Amite Bioenergy mill, opened in 2014 by British energy giant Drax, emits large – and sometimes illegal – quantities of air pollutants, including methanol, acrolein and formaldehyde, which are linked to cancers and other serious illnesses.“When I go out, I can’t hardly catch my breath,” Reed said. “Everything is worse since Drax came here.”The facility churns out billions of wood pellets each year to meet surging overseas demand for “sustainable biomass”, a renewable alternative to coal.The Amite BioEnergy wood pellet production facility in Gloster. Photograph: Kathleen Flynn/For the GuardianNow, Gloster residents are suing Drax, alleging that the company unlawfully exposed people to “massive amounts of toxic pollutants”, according to the October filing.Drax, one of the world’s biggest players in the booming biomass industry, has turned the UK’s largest coal power station, a mile-wide complex in rural Yorkshire, into what is essentially an immense wood stove fueled with Mississippi and Louisiana pine. The company, whose Yorkshire plant is among the UK’s largest single carbon emitters, has faced scrutiny and lawsuits in the UK for pollution and workplace safety violations.Its operations in the US are also beginning to draw legal challenges. “This case is about holding a multi-billion-dollar foreign corporation accountable for poisoning a small Mississippi community,” said Letitia Johnson, an attorney representing the group, in a statement.When the Gloster plant opened, many in the low-income, majority-Black town of 850 people were optimistic that it would revitalize the local economy. But some residents say it has brought little more than noise, dust and toxic air.Michelli Martin, a Drax spokesperson, said the company is making strides to reduce pollution.“The safety of our people and the communities in which we operate is our priority, and we take our environmental responsibilities very seriously,” Martin said. “As a company dedicated to sustainable energy production, high standards of safety and environmental compliance are always our top priority.”Drax’s Gloster plant is one of 30 large pellet mills – including five belonging to Drax – in the US south. Inside these plants, stacks of logs are stripped of bark, shredded, cooked in 1,000-degree tumble dryers, pulverized in hammermills, and pressed into pellets destined mostly for export. Photograph: Kathleen Flynn/The GuardianPellet exports from the US have quintupled, growing from 2 million tons in 2012 to about 10.5 million tons in 2023, according to the US Industrial Pellet Association. Most pellets are sent to the UK and Europe, where they are classified as a renewable energy source on par with solar and wind, making wood-burning eligible for massive subsidies, low-interest loans and other government incentives.But researchers say the drying, crushing and cooling processes at the mills emit air pollution that could be contributing to nearby residents’ health problems.“Air pollution is magnitudes higher in Gloster, especially with VOCs [volatile organic compounds],” said Erica Walker, a Brown University epidemiologist. She and a team of researchers set up air pollution monitors in the town and found clouds of VOCs concentrated around the mill and neighboring residential areas.“Literally, my first question when I visited Gloster was: ‘Who zoned this?’” she said of the mill, which abuts a mobile home park and is less than a mile from a children’s day care center. “It’s right out in the open. No acoustical barriers, no buffer of trees. It was shocking to see it operating right in the middle of the community.” Photograph: Kathleen Flynn/For the GuardianGloster mayor Jerry Norwood said small, remote mill towns like his can’t thrive without plants like Drax’s. “All of these small towns, we have nothing,” he said. “If big business don’t commit the big dollars, we don’t have the tax base. We have to have that for community growth.”Norwood did not respond to emailed questions about pollution or residents’ lawsuits against Drax, but in an October op-ed published before the suit was filed he wrote: “Those who oppose Drax and some in the media have made our town out to be some sort of smog-filled nightmare, but that is simply false. Along with my friends and neighbors who live, work and play in Gloster, I can assure you we breathe clean air.”Gloster residents, once hopeful that the mill would reverse the town’s decline – it has lost more than 20% of its population since 2000 – say it is only hastening it. Many say their experience should come as a warning to other communities.Longtime resident Carmella Wren-Causey, a plaintiff in the lawsuit against Drax, said she started using an oxygen tank in 2020 after developing breathing problems she blames on the mill. “We’re being poisoned slowly, right before our eyes,” she said through tears.“God gave me breath when he gave me life,” she said. “Drax took it away.”Carmella Wren-Causey in her car. Photograph: Kathleen Flynn/The GuardianA history of violationsDrax, one of the world’s largest pellet companies, has racked up nearly $6m in violations for its operations in Mississippi and Louisiana over the past four years.In 2020, the Mississippi department of environmental quality, following years of prodding from environmental groups, found the company’s Gloster mill was emitting an average of 796 tons of VOCs per year – more than three times the limit allowed under the mill’s permit – and fined the company $2.5m.Louisiana officials, too, found that Drax had been breaking several of its air quality rules, and in 2022 reached a settlement in which Drax paid $3.2m but admitted no wrongdoing.The Drax power station in North Yorkshire. Photograph: Gary Calton/The ObserverThe settlement was the largest in more than a decade for Louisiana environmental officials, but it appears to be the extent of any serious efforts to rein in Drax’s pollution in Louisiana, said Patrick Anderson, an attorney who, when working with the Environmental Integrity Project, reviewed Drax’s pollution history in Mississippi and Louisiana.The Louisiana department of environmental quality did not respond to requests for comment.Matt White, vice-president of Drax’s North American operations, said that Drax has since made several upgrades and changes to reduce emissions, including installing a thermal oxidizer at the Gloster mill that they say essentially burns away VOCs.“We take our environmental responsibilities and compliance extremely seriously,” White said. “Compliance is at the foundation of everything we do, and we have invested a lot of hours and resources with the goal of continuously improving our operations.”People support a Drax protester who was detained by UK police in 2024. Photograph: Gary Calton/The ObserverDespite the upgrades and repeated promises to do better, Drax continued to incur fines for pollution violations. In late 2024, Drax agreed to pay $225,000 for exceeding the Gloster mill’s limits for hazardous air pollutants, particularly for methanol, which were recorded at nearly double the permitted threshold, according to the MDEQ.In April 2025, amid complaints from residents, the MDEQ denied Drax permission to increase its emissions. Its reversal of that decision in October – allowing Drax’s Gloster mill to become a “major source” of hazardous air pollutants – triggered the lawsuit against the company.A representative from the MDEQ declined to comment on the lawsuit, but said: “MDEQ takes seriously its obligations to protect human health and the environment.”The $6m in penalties over the past four years are a drop in the bucket for Drax, Anderson said. The company raked in $1.4bn in profits in 2024 and about 1.3bn in 2023, according to Drax’s adjusted earnings reports.“Drax is so profitable and so subsidized that it powers through all of this,” Anderson said. “The fines don’t hurt their bottom line.”Researchers have found several signs that these pollutants are having real consequences.The air monitors that Walker and her team installed detected unexpected spikes in VOCs during the night, something that lines up with residents’ complaints of foul odors and difficulty breathing after dark.“At night, it’s always worse,” Gloster resident Robert Weatherspoon said. “It smells disgusting.”Robert Weatherspoon once jogged daily but now struggles to breathe. Photograph: Kathleen Flynn/The GuardianThis could indicate pollution “dumping” during certain hours, Walker said.Drax disputed the dumping claim. “Any suggestion that we manipulate our operations to avoid complaints or detection is completely false,” Martin said.Walker’s team also found that the closer children lived to the mill, the heavier they were. “It fits with some of the things we heard at community meetings,” Walker said. “You don’t want your kids playing outside because the air’s polluted. If they’re staying inside, how are they getting physical activity?”It’s not just the hazardous chemicals that are keeping residents up at night.Glen Henderson, a resident of Urania, Louisiana, whose Drax mill opened in 2017, described near-constant clanging and banging from the mill. Lights glow over the tops of an ever-thinning band of trees between his home and the mill, nearly a mile away, and at daybreak, a powdery substance often coats his truck.“This noise and dust – what are the long-term effects of all that?” he asked.In 2024, Walker and a team of researchers from the University of Mississippi and Drexel University published a study based on a noise exposure assessment in Gloster.Children walk home after being dropped off by their school bus in Gloster. Photograph: Kathleen Flynn/For the GuardianThey found the mill’s operations and truck traffic sometimes topped 70 decibels, whereas the comparably sized Mississippi town of Mendenhall, which does not have a pellet mill, was typically 10 decibels quieter.“That’s an enormous difference,” Walker said. “It’s like turning a faucet into Niagara Falls.”Martin said Drax follows federal noise abatement guidelines and insulates buildings to mitigate sound levels.“Pellet mills generate noise as part of the manufacturing process from the operation of equipment,” Martin said. “The noise from facility operation is consistent with the surrounding industrial plants and does not contribute to significant impacts above existing background noise.”A growing body of research has linked chronic noise exposure to high blood pressure, heart attacks, anxiety and depression.“Noise disrupts your sleep, disrupts your mood, and sets off a stress response that’s like your ‘fight or flight’ response, which makes your body ready to fight a threat or run from it,” Walker said. “The constant stimulation of that response can cause all kinds of health problems.”Community leader Krystal Martin shows a photo of the Gloster facility. Photograph: Kathleen Flynn/The GuardianThe company recently expanded a mill in Alabama, established a North American headquarters in Monroe, Louisiana and opened an office in Houston to lead its carbon capture and sequestration enterprises.Over the past six years, the Urania mill alone has produced enough pellets to fill the New Orleans Superdome nearly twice.Yet several residents in Gloster and Urania said that output has not revitalized their economies. Each of the three large Drax mills in Louisiana and Mississippi employs between 70 and 80 people, a fraction of the workforce supported by many past mills. In Gloster, only 15% of Drax’s employees reside in the community, according to the company. Photograph: Kathleen Flynn/For the GuardianMabel Williams, a lifelong resident of Gloster, never wanted a Drax job, but she had high hopes that the mill would employ enough people to breathe life back into downtown. Walking along a largely vacant Main Street, her memories crowded every empty lot and darkened window.“There were people everywhere,” said Williams, 87, who spent decades cleaning the homes of the white residents who have mostly moved away. “This was a clothing store and that was a jewelry store owned by a German man. And over there, my mamma worked at the cafe.” Across the train tracks was the Black business district, with four barbershops, restaurants and music venues, she said. “I get excited when I think about what Gloster had,” she said.Williams still has faith that Gloster is capable of a revival, but she no longer believes it will be thanks to Drax.“Drax is making so much money,” she said. “They’ve got to spend that money some kind of way, but they’re not spending it here.”A longer version of this story is forthcoming from Verite News

This Year in Conservation Science: Whales, Birds, and Killer Roads

We asked conservation researchers around the world to send us their favorite papers of 2025. They address the planet’s most pressing problems — and important solutions. The post This Year in Conservation Science: Whales, Birds, and Killer Roads appeared first on The Revelator.

The road to hell is paved with … more roads. That seems to be the message of one of this year’s most striking conservation papers. The research, published this April in the journal Current Biology, linked the “explosive growth” of secondary roads — those that branch off what the papers call “first-cut roads” — to tropical deforestation around the world. These aren’t the typical suburban Streets, Drives, and Courts that spring up around developments. They’re “illicit, unplanned, often illegal roads,” says the paper’s senior author, William Laurance, distinguished research professor at James Cook University. The research was led by ecologist Jayden Engert. “The numbers are almost crazy,” says Laurance. “For example, we found an enormous proliferation of secondary roads in the Congo Basin, Amazon, and New Guinea — especially in the Amazon,” where every mile of official roads generated around 50 miles of unofficial roads. “These secondary roads are opening tropical forest frontiers like a flayed fish, exposing them to illegal land-grabbers, loggers, poachers, miners, and illegal drug producers whose activities are driving rampant forest loss.” Sadly, Laurance says, these secondary roads don’t exist on official maps and they’re hard for governments to control. But research like this helps to document them — and that’s the first step to addressing the problem. That can also be said of the other new papers and reports sent to us this month by conservation experts around the world who sent us their best or favorite research from 2025. Forests Connect Us Other research also called out the importance of forests — this time connecting the dots between places like New York City’s Central Park and other North American forests, especially rapidly disappearing landscapes in Central America. “It’s easy to think of migratory birds as ‘ours,’ tied to a particular state or region, but their survival depends just as much on distant habitats far from home,” says the study’s lead author, Anna Lello-Smith of the World Conservation Society. “Using millions of bird observations from the Cornell Lab of Ornithology’s eBird platform, our study shows that eastern North America’s forest birds rely on Central America’s last large tropical forests — the Five Great Forests — to survive migration and the winter. Because billions of migratory birds funnel into the narrow land bridge of Central America, these forests hold staggering concentrations of warblers, thrushes, and hawks — in some cases nearly half their global populations — yet several are rapidly disappearing due to illegal ranching and fires.” The study identified what it called “sister landscapes” — sites across the U.S. and Canada that are linked to the Five Great Forests by shared bird species. Lello-Smith says this offers “a roadmap for connecting bird lovers and communities across the hemisphere to help protect and restore the tropical forests that keep our birds in the sky.” Three From the Ocean Shifting from the skies to the seas, frequent Revelator contributor and shark scientist David Shiffman shared new research by Mark E. Bond and other experts about how the world has improved conservation and management of sharks and related species. “The ocean science and conservation community has invested a lot of time, energy, and resources into protecting sharks via the Convention on International Trade in Endangered Species,” says Shiffman, who was not involved in this research. “We’ve seen promising signs that this approach is working for years, but Bond et al. is the first global-scale analysis of the impacts of CITES protections on shark management regulations around the world. They found that several countries who previously had no shark conservation or management regulations of any kind made their first regulations — a huge step. They also found improvements in regulations of more than half of shark fishing and exporting nations, including many that are substantive and important. There is no silver bullet to complex conservation challenges, but these results are clear that for many shark species in many countries, CITES helps.” All ocean species face an ongoing and growing threat from human activities, though. That’s why a dozen conservation experts — including Callum M. Roberts, Sylvia Earle, and Stuart Pimm — recently penned a commentary in Nature calling for an end to extraction in the high seas in perpetuity. Such a move, the authors argued, would protect species and the planet from increased fishing, deep-sea mining, and other threats. Pimm called it his “most important contribution” of the past year. On a more specific ocean note, one recent paper looked at critically endangered Rice’s whales, who scientists identified less than five years ago. Unfortunately the news coverage of that discovery failed to shift the needle on the forces endangering the whales. “My co-author and I took a communication and media studies approach to research Rice’s whale conservation and management and intentionally included insights that anyone with an interest in conservation can use,” says Marcus B. Reamer, a lecturer at the Rosenstiel School of Marine, Atmospheric, and Earth Science. “We highlight the essential role of communication and media in conservation and offer actionable strategies for navigating media systems and communicating effectively in challenging political and ecological environments, providing a roadmap for individuals and organizations working on conservation challenges across ecosystems and geographies. It’s a unique direction for marine mammal conservation research — and timely given ongoing efforts to weaken environmental laws and ramp up oil and gas production in the Gulf of Mexico.” Indigenous Science Two researchers called out the importance of traditional Indigenous knowledge and related systems. First, Liber Ero Postdoctoral Fellow Sara E. Cannon sent a paper about “a respectful and transparent way to uphold ancestral Indigenous Pacific salmon stream caretaking knowledge, longstanding Indigenous rights and relationships to land and waters, and our joint responsibilities to care for these watersheds.” “This paper is an essential read for conservation practitioners and researchers across Canada,” says Cannon, who was not involved in the research. “It recenters Indigenous laws, governance systems, and ancestral caretaking knowledge as foundational to restoring Pacific salmon and their watersheds. By documenting Indigenous-led restoration initiatives across British Columbia, it offers tangible, place-based examples of how ethical collaboration and Indigenous leadership can guide more just and sustainable approaches to salmon recovery. It invites readers to rethink restoration not only as ecological repair, but as the renewal of relationships, rights, and responsibilities between people and salmon.” Aerin Jacob, director of science and research at the Nature Conservancy of Canada, included a paper she coauthored about navigating the divide between science and policy. “Environmental decision-makers often rely on natural science or familiar expert networks while feeling uncertain about how to meaningfully include Indigenous knowledge, social science, or local experience,” Jacob says. “This can lead to decisions that are less effective and less supported. Our study examines what Canadian science–policy professionals consider ‘good evidence,’ why some evidence gets used or overlooked, and how to build more balanced, credible decision-making. I like this paper because it’s frank about challenges while also focusing on solutions.” And as a reminder that important science can come in many forms, Jacob also sent a report (funded in part by her organization) entitled “A Guide to Choosing and Using Community-Based Data Management Systems for Indigenous Land-Based Programs.” “Around the world, Indigenous guardians collect vital information about nature and people — including photos, maps, datasets, stories, and more,” Jacob says. “It’s crucial to keep that information organized, secure, and aligned with community values. I’m a big fan of this new work from northern Canada for two reasons. First, it supports guardians and other land-based program staff to decide what matters most to them and how they want to proceed. Second, it helps external parties to be better partners in the technical and governance aspects of data, software, funding, infrastructure, staffing, and more.” Quick Hits Chris Shepherd, another frequent Revelator contributor and source, sent an interesting (and worrying) paper about Canada’s role in the trade of live monitor lizards. “Very little is known about the reptile trade in Canada, or about Canada’s role in the international wildlife trade at all,” he says. “Here we focused on the trade in monitor lizards in Canada and found Canada to be a major player. This issue is largely unknown in Canada, and we are only just starting to scratch the surface.” Dominick A. DellaSala, senior conservation scientist associate at the Conservation Biology Institute and another Revelator contributor, sent a new paper he coauthored that suggested a conservation opportunity in the Montana’s Yaak River Watershed. The paper “provides new protected area assessments for the Northern Rockies and identifies proposed climate refugia based on climate modeling and GAP analyses methods,” he says. Has the world failed the Sumatran rhino? K Yoganand of the Malaysian organization Bringing Back Our Rare Animals sent a coauthored paper published in the journal Pachyderm detailing the status, history, and fraught future of this critically endangered species. “We present a sobering case study of how decades of missteps, indecision, and cognitive biases have driven the Sumatran rhinoceros to the brink of extinction,” Yoganand writes. “For anyone committed to preventing future extinctions, the paper offers both a cautionary tale and a roadmap for how conservation must adapt to avoid repeating these failures.” Finally citizen scientist Paula Borchardt wrote to remind us that everyday citizens play an important, ongoing role in collecting data about the natural world. “I’m an artist, journalist, naturalist, and citizen scientist who publishes a weekly blog sharing my art and stories about natural history, mostly about my Tucson, Arizona, backyard and the environment here in the Sonoran Desert.” She pointed out one recent entry, “describing my husband’s and my project to grow saguaros from seed, to help an effort by several Tucson-based organizations to support saguaros and combat their declining numbers.” The striking headline: “We have 1,518 saguaros on our patio.” That’s it for this year’s “This Year in Conservation Science.” But the new year is around the corner, and with it come 12 more months of new, exciting, important research about endangered species, habitats, environmental justice, climate change, and related topics.

After the L.A. fires, heart attacks and strange blood test results spiked

A new study is the latest of several recent research papers documenting the physical toll of January's fires.

In the first 90 days after the Palisades and Eaton fires erupted in January, the caseload at Cedars-Sinai Medical Center’s emergency room looked different from the norm.There were 46% more visits for heart attacks than typically occured during the same time period over the previous seven years. Visits for respiratory illnesses increased 24%. And unusual blood test results increased 118%.These findings were reported in a new study published Wednesday in the Journal of the American College of Cardiology. The study, part of a research project documenting the fires’ long-term health effects, joins several recent papers documenting the disasters’ physical toll.While other U.S. wildfires have consumed more acres or cost more lives, the Palisades and Eaton fires were uniquely dangerous to human health because they burned an unusual mix of materials: the trees, brush and organic material of a typical wildfire, along with a toxic stew of cars, batteries, plastics, electronics and other man-made materials.There’s no precedent for a situation that exposed this many people to this kind of smoke, the paper’s authors said.“Los Angeles has seen wildfires before, it will see wildfires again, but the Eaton fire and the Palisades fire were unique, both in their size, their scale and the sheer volume of material that burned,” said Dr. Joseph Ebinger, a Cedars-Sinai cardiologist and the paper’s first author. The team did not find a significant increase in the overall number of visits to the medical center’s emergency room between Jan. 7, the day the fires began, and April 7. The department recorded fewer in-person visits for mental health emergencies and chronic conditions during that time compared to the same time period in earlier years, said Dr. Susan Cheng, director of public health research at Cedars-Sinai and the study’s senior author.The increase in visits for acute cardiovascular problems and other serious sudden illnesses made up the difference. The study team also looked at results from blood tests drawn from patients visiting the ER for serious physical symptoms without immediate explanation — dizziness without dehydration, for example, or chest pains not caused by heart attacks.Their blood tests returned unusual results at a rate more than double that seen in previous years. These atypical numbers cut across the spectrum of the blood panel, Cheng said. “It could be electrolyte disorder, change in protein levels, change in markers of kidney or liver function.”The rate of unusual test results held steady through the three-month period, leading the team to conclude that exposure to the fires’ smoke “has led to some kind of biochemical metabolic stress in the body that likely affected not just one but many organ systems,” Cheng said. “That’s what led to a range of different types of symptoms affecting different people.”Joan Casey, an environmental epidemiologist at the University of Washington who was not part of the Cedars-Sinai team, noted that the study found health effects lasting over a longer period than similar studies have.Three months “is a substantial length of time to observe elevated visits, as most studies focused on acute care utilization following wildfire smoke exposure find increased visit counts over about a weeklong period,” Casey said. Her own research found a 27% increase in outpatient respiratory visits among Kaiser Permanente Southern California members living within 12.4 miles of the burn zones in the week following the fires.“The L.A. fires were such a severe event, including not only smoke, but also evacuation and substantial stress in the population, that effects may have lingered longer,” Casey said.Thirty-one people are known to have died as a direct result of injuries sustained in the fires. But researchers believe that when taking into account deaths from health conditions worsened by the smoke, the true toll is significantly higher.A research letter published earlier this year in the Journal of the American Medical Assn. calculated that there were 440 excess deaths in L.A. County between Jan. 5 and Feb. 1. That paper looked at deaths caused by a variety of factors, from exposure to air pollution to disrupted healthcare as a result of closures and evacuations.On Tuesday, a team from Stanford University published itsprojection that exposure to the fires’ smoke, specifically, led to 14 deaths otherwise unaccounted for.Wildfire is a major source of fine particulate pollution, bits measuring 2.5 microns or less in diameter that are small enough to cross the barriers that separate blood from the brain and the lungs’ outer branches.Compared with other sources, wildfire smoke contains a higher proportion of ultrafine particles miniscule enough to penetrate the brain after inhalation, Casey told The Times earlier this year. The smoke has been linked to a range of health problems, including dementia, cancer and cardiovascular failure.In the last decade, increasing numbers of wildfires in Western states have released enough fine particulate pollution to reverse years’ worth of improvements under the Clean Air Act and other antipollution measures.
