February 23, 2026 – The Supreme Court struck down many of President Donald Trump’s tariffs on Friday, prompting approval from multiple farm groups, several of which released statements asking him not to impose new tariffs and emphasizing farmers’ need for clarity.

The decision applied to the across-the-board 10 percent tariff and higher reciprocal tariffs on individual countries Trump announced last April under the International Emergency Economic Powers Act.

However, over the weekend, Trump announced new overall tariffs, using powers under a different law, section 122 of the Trade Act of 1974. He then increased that broad tariff rate to 15 percent.

“Despite the Supreme Court’s ruling against one form of tariff, we are not backing down—not even for a second,” Secretary of Agriculture Brooke Rollins said in a post on X.

Rollins said new trade deals enabled by the tariffs led to an agricultural trade deficit of $41.5 billion in 2025, a drop from the $50 billion deficit that U.S. Department of Agriculture (USDA) economists had predicted. The 2025 deficit was lower than predicted, but it increased significantly compared to the previous five years.

Some countries, such as China, have shifted a portion of agricultural purchases to other countries in reaction to the tariffs, shrinking markets for farmers, who have also been hit by higher prices on equipment, fertilizer, and other imported inputs.

The end of higher reciprocal tariffs on some countries could lead to changes to prices of some of those goods, but separate tariffs on steel and aluminum that have raised prices of farm machinery remain in place. Under the new law Trump is employing, the 15 percent overall rate will need Congressional approval after 150 days.

“We call on Congress to exercise its oversight role to ensure trade policy supports—not undermines—America’s family farmers and ranchers,” National Farmers Union president Rob Larew said in a statement. “Over the past year, tariffs have raised input costs, disrupted export markets and triggered retaliation against U.S. agricultural goods. In an already fragile farm economy, uncertainty has hit family operations hardest.” (Link to this post.)

For decades, scientists viewed the genome of a newly fertilized egg as a structural "blank slate"—a disordered tangle of DNA waiting for the embryo to wake up and start reading its own genetic instructions. In research published in Nature Genetics, Professor Juanma Vaquerizas and his team have found that a surprising level of structure is already in place. They've developed a breakthrough technology, called Pico-C, which enables scientists to see the 3D structure of the genome in unprecedented detail.

Beaver dams are critical to river health and a source of biodiversity. They create wetlands, slow water and improve water quality. They also reduce flood peaks and delay runoff. But beaver dams are often blamed when extreme rainstorms cause flooding—especially when they fail.

Ribosomes are the components of cells that read RNA and build proteins. Without the ribosome, the chemistry of life would still be catalyzed by raw RNA. And yet the origin of the ribosome remains a mystery. In a Perspective published in PNAS Nexus, Michael Lynch and Andrew Ellington note that the ribosome, which creates all cellular proteins, is itself composed of multiple proteins. How, then, did the ribosome first come to be?

This story was originally printed in Windspeaker and appears here with minor style edits.


A documentary about a woman who spent the majority of her life preserving nēhiyawēwin — the Cree language — will have its world premiere in “Vancouver” next month.

The film, titled A Cree Approach, documents the life of Freda Ahenakew, born in 1932 on the Ahtahkakoop Cree Nation reserve in “Saskatchewan.” She passed in 2011.

The film, written and directed by Ahenakew’s granddaughter Tristin Greyeyes, will screen March 7 at the VIFF Centre as part of the Gender Equity in Media Festival (GEMFest), which runs from March 5 to March 8. The festival will show 35 films from 13 countries created by women and gender-diverse filmmakers.

Greyeyes began work on A Cree Approach in 2021.

“It was a passion project for sure and very personal,” she said. “I’m excited to finally share it.”

Greyeyes was keen to get Ahenakew’s story on the big screen.

“Her story resonates with me and helped me get through my schooling being a single parent,” she said. “And it’s just like one of those lores you hear growing up, that a single mom of 12 going back to school after she dropped out. It’s just such a powerful story of resilience. I just wanted other people to hear it.”

Greyeyes, a member of Muskeg Lake Cree Nation in “Saskatchewan” who has lived in “Vancouver” for the past nine years, is hoping her documentary is enlightening.

“I hope non-Indigenous people understand Indigenous people’s struggle for language revitalization and more reclamation and why it’s important and how it’s affected our families,” she said. “And for Indigenous people, I hope they get inspired to want to learn their language, if they’re not already actively doing that.”

When she first started doing interviews for A Cree Approach, Greyeyes envisioned creating a short film. Once Greyeyes had completed her interviews and re-enactments, she decided the film would be best suited to being considerably longer. The final documentary is 70 minutes.

“I just thought it should be a feature, not out of ego or anything, but more out of the amount of information that I could be sharing and the amount of archival stuff I found,” she said. “Then I spent probably a year asking for money to finish it.”

Ahenakew spent some of her teenage years attending residential “school” in “Prince Albert,” but dropped out of high school to get married.

She returned to her academics in 1968, attending high school at the same time as several of her children. Besides wanting to complete her own high school studies, Ahenakew returned to the classroom in order to be a role model to some of her own children, who were losing interest in their academics.

Ahenakew went on to study at the University of Saskatchewan, while also teaching Cree at the school.

She later earned a master’s degree from the University of Manitoba. Her thesis, which was eventually published, was titled Cree Language Structures: A Cree Approach.

Greyeyes believes it simply made sense to select this title when naming her film.

“I just think it was very fitting for the documentary about a Cree woman and her life and the theme of speaking Cree,” she said. “And I’m Cree too.”

A Cree Approach will also be screened at the Sundar Prize Film Festival, which will be held from April 23 to April 26 in “Surrey, B.C.”

Greyeyes said the film will have its “U.S.” premiere at a festival this spring. Details for that screening have yet to be announced.

Other Indigenous films that will screen at GEMFest are W7éyle (Moon’s Wife)Forest Echoes and Yáamay: An Ode to Blooming.

*W7éyle (Moon’s Wife)*is a short created by Secwépemc filmmaker Amanda Wandler. The film is about a woman who has to make a difficult choice when her partners discover a pill for immortality. The woman has to decide whether she wants to have children or take the pill and live forever.

Forest Echoes is directed by Eva Grant, a member of St’at’mic Nation. This short is a love story featuring Echo and Wild, a pair of urban Indigenous land defenders.

Yáamay: An Ode to Blooming is a short film that features the voices and experiences of Indigenous women from “California” reciting their poetry. The film is co-directed by Camaray Davalos and Casse Kíihut.

More information on all of the GEMFest films is available here.

Every year, monarch butterflies make their iconic migration across North America. The journey spans thousands of miles and three countries. However, very little is known about this migration, resulting in the lack of concrete data about a very important life stage of these butterflies. Scientists are now using lightweight radio tags to get insights into the mysterious migration of monarch butterflies. Using the technology, they have been able to understand how and where the butterflies move, filling crucial gaps in the data.

KATHMANDU — As Nepal gears up for parliamentary elections on March 5, 2026, the remote high-altitude villages of Khumbu, home to the Indigenous Sherpa people, Sagarmatha (Everest) and some of the world’s most iconic trekking trails remain largely untouched by the political frenzy sweeping towns and cities across the country. While posters, rallies and door-to-door campaigns dominate the lowlands, harsh winter conditions coupled with mass seasonal migration have left villages such as Namche Bazaar, Lukla and Pangboche in the Sagarmatha region eerily quiet. “With most residents having moved to Kathmandu [Nepal’s capital], the candidates will arrive here only at the last minute as campaigning [for the Khumbu constituency] goes on in Kathmandu itself,” Sonam Sherpa, a resident of Lukla, told Mongabay by phone. In high-altitude communities beneath Sagarmatha, worsening climate impacts such as retreating Himalayan glaciers and frequent avalanches are growing risks, yet election debates still focus mainly on immediate infrastructure needs such as roads, electricity and drinking water rather than long-term environmental resilience, residents say. “We only talk about climate change among ourselves,” Sonam Sherpa said. The candidates, meanwhile, talk about issues related to infrastructure such as roads and electricity, he adds. Villages wear a deserted look in the Khumbu region in Nepal. Image by Shashwat Pant. Since the first ascent of Everest by Edmund Hillary and Tenzing Norgay in 1953, the Sherpa people, known for their ability to thrive at high altitudes, gained global visibility and mobility. Second-generation Sherpas often pursue higher education and professional careers abroad. Third-generation…This article was originally published on Mongabay

The decline of California's kelp forests since the marine heat wave of 2013–17 has seen only minor recovery despite heroic efforts at restoration carried out by scientists, fishermen, coastal tribes, volunteer divers and conservationists. Nor is the threat to kelp localized. Rather, the loss, like the expansion of mega-wildfires on land from Los Angeles to Siberia and from Canada to Australia, comes in response to an ever-warming world where 90% of the human-generated heat from the burning of fossil fuels is absorbed by the ocean.

In the popular imagination, Iowa represents the American Heartland, with sweeping fields of corn and soybeans tended by farmers who also act as bellwethers for national politics.

But it’s much harder to imagine the corporate, political, and cultural forces shaping which crops these farmers plant, or how they grow them, or why industrial hog facilities now fill the horizon, or who, exactly, benefits from it all.

These are the very issues that Art Cullen has been writing about for more than 30 years at the Storm Lake Times Pilotin Storm Lake, Iowa*.*

Cullen, a native of Storm Lake, is the editor; his brother, wife, and son are also all on staff. And while the newspaper exists mainly to serve the town of about 11,000 people in Iowa’s northwestern quadrant, Cullen’s columns have found a broader audience because the topics he covers have national significance.

In 2017, he won a Pulitzer Prize for editorials that “successfully challenged powerful corporate agricultural interests in Iowa.” He’s also written two books; his latest, Dear Marty, We Crapped In Our Nest: Notes From the Edge of the World, a collection of his columns, was published last year.

As the country heads into a pivotal election year, many of the food and farm policy issues Cullen knows best are rising in political and cultural prominence: water pollution from industrial animal agriculture, illnesses linked to farm chemicals, the impacts of continued consolidation, and others.

We spoke with Cullen to find out more about what he’s seeing and hearing on the ground and which party he thinks will be able to respond to a growing populism that includes a focus on corporate power in the food system.

Immigration operations in Minnesota have been front-of-mind right now for much of the country, including farmers. How have Storm Lake residents reacted to these federal operations and the protests?

Storm Lake is majority minority; that is, majority Latino. So people here feel very threatened and fearful. They’re laying low. They are not downtown.

But there is a kind of a tacit acknowledgment here that meatpacking plants owned by the majors are not getting raided, because I think they figured out from the pandemic, when they shut down the Storm Lake and Waterloo pork slaughter plants for Tyson and meat prices shot up 50 percent in about a week, they realized, “Oh, we can’t really deport all these immigrants because they’ve got to cut meat.”

Now, that doesn’t mean that if [White House Deputy Chief of Staff for Policy] Stephen Miller wakes up with a bad cup of coffee, things couldn’t change. But I think they recognize that they have to keep the meat churning.

In Dear Marty, so many of the chapters represent topics that are entering the national conversation in a bigger way right now, like immigration, cancer, and more. Does this feel like a pivotal time or a turning point for Iowa?

Yes, in a lot of different ways. This is the first time since 1968, for example, that we’ve had open U.S. Senate and governor’s races. So, there’s going to be a big political turning point in Iowa. This has been an entirely Republican congressional delegation and an entirely red state government, led by Kim Reynolds, who’s not running for reelection as governor. And [Republican Senator] Joni Ernst is not running for reelection.

Democrats do have a real opportunity to pick up those two seats, which would change the whole political atmosphere in Iowa. We’ve raced backwards in time in terms of acknowledging our history with African-Americans and Native Americans, smothering all that, shaming gays, etc. It’s just been awful for the past 10 years.

“Democrats do have a real opportunity to pick up those two seats, which would change the whole political atmosphere in Iowa.”

There’s a lot of other changes that are taking place that are not necessarily controlled by us, but nature is making some pretty big changes in the way livestock are raised, for example. Disease is rampant, and cattle are running out of water in the Great Plains. There are beef plants closing and opening. So agriculture is really in a great state of flux right now, and obviously that’s vital to Iowa.

We’ve tried this 50-year experiment in supply-side economics, and it hasn’t worked. It hasn’t worked for agriculture. It certainly hasn’t worked for rural communities. It hasn’t worked for our political culture. It’s polluting the water. And so there’s another inflection point. They’re all related to each other.

Let’s tease out some of the things you mentioned. Water quality is a big one. In your new series, “What’s Eating Iowa?,” you have an episode on water quality. Are you hearing from Iowans when you’re traveling around the state that this is a really big concern? And are people linking it to agriculture?

Yes and yes. What we’ve done is we’re producing a series of four medium-length documentaries, 16 to 20 minutes, on water quality, cancer, and agriculture resiliency in an era of climate change and rural consolidation. Again, they’re all related. They all point to each other.

Last summer, a thousand people showed up at Drake University to talk about anhydrous ammonia [fertilizer] on a beautiful summer evening. Iowans just don’t do that, right? There are 500,000 people in the Des Moines metro area, and a thousand of them show up to discuss nitrate levels in the Raccoon River. That’s pretty remarkable. People are upset about water quality in Iowa.

But there’s this Republican legislature that’s funded by the agribusiness cartel that won’t allow a real discussion of regulation of agriculture, regulating drainage districts that are fouling these rivers, and they certainly won’t allow a discussion about what the root causes of cancer are in Iowa. We don’t really know.

We know that we have the second highest cancer rate in the country, next to tobacco central, Kentucky. And we have a very high rate of youth cancer here. We have the highest rate of breast cancer and prostate cancer in North America, right where I live, which is where we also have the highest concentration of livestock.

People there also smell hog shit in the air every day when they open up the door. So they are making connections between environmental influences, industrial practices, and cancer. They’re making the connections very slowly about how these agribusinesses actually ruined rural communities.

Do people feel like they can ask those questions or speak out? Because generally in Iowa, making those connections can get you labeled as anti-farmer.

That’s exactly what’s happening. In fact, there is a Democrat research scientist named Chris Jones, a water researcher who is running for Iowa Secretary of Agriculture. Kind of a quixotic mission in Iowa, a Democrat running against an incumbent Republican; that’s really a tall task. And the first thing out of the incumbent’s mouth is that Chris Jones is “anti-farmer,” because he favors clean water.  [You have to be] pro-pollution to be pro-farmer.

Of course, it’s bullshit. You can have prosperous agriculture and clean air and water. They’re not mutually exclusive. But it’s really a long campaign of disinformation that’s been occurring. Propaganda. Cropaganda, we call it.

The current state agriculture secretary, Mike Naig, previously worked for Monsanto. The thing that has always interested me is the sense among farmers that corporations—especially, chemical corporations, the pesticide companies and seed companies—are on the side of the farmer. How did that happen?

It’s on every ad you see on TV during girls’ basketball games, which is the major cultural event.

It’s just pounded into your head that fertilizer companies and herbicide companies are your partner in yield, and yield is everything. And because you can’t get the price you want, you have to have the yield. So, [farmers are] locked in to maniacally chasing that pot at the end of the rainbow.

“It’s really a long campaign of disinformation that’s been occurring. Propaganda. Cropaganda, we call it.”

And then the banker gets involved and says, “You know, we really need to be doing it this way.” And the landlord is reading Successful Farming magazine and says, “We should be doing it this way.” And then the tenant farmer says, “Well, yeah, I guess I better do it your way.”

So there really isn’t a lot of room there for the farmer to actually act as steward, and they get locked in by this dominant culture in Iowa that says you must plant every acre in corn and soybeans and then feed it to hogs.

Do you think that the pesticide immunity laws that Bayer has been pushing for—which would make it harder for individuals to sue over claims pesticides caused their illnesses—might change that? Are people seeing that those companies might not have their best interests in mind?

Yeah, it’s coming at a very interesting time in Iowa, when there’s also an attempt to lay CO2 pipelines across the state. So a lot of very conservative, libertarian, property-rights Republicans are split with the more traditional, corn-ethanol Republicans over property rights and libertarian ideals. So, it’s come at a very bad time for Bayer to be the big, bad corporate player, because they’re getting lumped in with the CO2 players, the ethanol boys.

There’s kind of an anti-corporate populism rearing its head right now in the Republican Party. It presents a real opportunity for Democrats, and they appear to be blowing it, of course, by siding with the pipeline companies in a vain attempt to hang on to the Pipe and Steam Fitters Union.

The pesticide immunity bill is surfacing again in the Iowa legislature this session. They’re pushing it again, just because it’s so important in Iowa. If it goes in Iowa, it’ll go in Illinois, in Indiana.

In agricultural spaces, politicians often ignore the opportunity to speak more about corporate consolidation, including hog farms, the hollowing out of rural communities, and rural Iowa towns that no longer have grocery stores. Which party do you think is going to win on that issue?

Well, in Iowa, there’s only one party, that’s the problem, Especially, in western Iowa, I think one Democratic senator lives west of Interstate 35, which bifurcates the state east and west. There is no Democratic Party where I live, functionally speaking. The whole disagreement is between the libertarians and the Farm Bureau Republicans. That’s where the contest is.

But it may allow a Democrat to slip in as governor. Because [Republican U.S. Congressman] Randy Feenstra is considered to be a tool of the Farm Bureau. It might allow [Democrat State Auditor] Rob Sand, who’s armed with about $13 million, to slip past Randy Feenstra, because I think libertarian turnout could be suppressed by these disagreements over pipelines. Plus, there’s a lack of enthusiasm for the Trump administration, and shooting people dead in the streets doesn’t play well with libertarians.

Are there farmers and farm groups that you see pointing Iowa in a better direction?

I guess I can draw some optimism from the Practical Farmers of Iowa and secondarily, the Iowa Farmers Union, which would be the alter ego to the Farm Bureau. The Farmers Union is very small, but they’re getting very active politically.

“There are a lot of really smart guys who understand the weather. They realize they just can’t go on doing what they’re doing.”

The Practical Farmers of Iowa are interesting in that they were considered, you know, Birkenstock kind of people, and they would get 10 farmers at a field day. Now, they’ll get over 100 farmers, or even a thousand, at a field day. They have a huge convention that that goes on for three days now, and it all revolves around sustainable, regenerative, or resilient agriculture—whatever you want to call it. That really is something that the conversation is changing in Iowa. It’s just very slow.

There are a lot of really smart guys who understand the weather. They realize they just can’t go on doing what they’re doing mining the surface, growing in a petrochemical base. They just know it’s not working for them. And [they know] that cover crops are working for them, and other conservation techniques, and that they do save money, a lot of money.

Trump came to Iowa recently and spoke in front of a crowd. He talked a lot about ethanol, among other things, and I know there were some protesters outside. What did that recent visit, reveal, if anything, about, agricultural politics going into the midterms?

Well, first of all, it was widely reported that there were about 700 people inside the event center and [thousands] outside protesting.

It was also reported that the enthusiasm inside was fairly muted for Trump, because his base in Iowa is not real happy with the whole trade war with China. Farmers are having a hard go of it because there is no soybean market.

They vote for him, but they don’t trust him. I don’t know what they thought they were getting out of him. It just sort of mystifies me.

You’ve been on a book tour, and you’ve said that everywhere you went, one message emerged: “We want our good old Iowa back.” What is that Iowa?

They want independent growers. They want civil conversations. They want strong schools. And I really don’t think they are that crazy about chasing off immigrants. What people want is that “Iowa nice” that we used to know. It’s become “Iowa nasty.” When you’re shutting out trans people and saying they don’t have civil rights protections or disavowing Black history, that’s not in the spirit of George Washington Carver, an Iowa State alumnus.

Rice, maize, and cassava crops cumulatively account for approximately 11% of total global deforestation—exceeding that of cocoa, coffee, and rubber—according to an analysis between 2001 and 2022, published in Nature Food. These staple crops should not be overlooked in global efforts to reduce deforestation, the authors argue.

For many animals, siblings are a key component of their social environment during early life. Previous research has shown that the early social environment is important, but it has not yet been clear whether the number of siblings or the nature of their interactions is the decisive factor. "The early social environment is often treated as a single, uniform factor," says Bruno Camargo dos Santos, behavioral ecologist of Wageningen University & Research and lead author of a new study published in the Proceedings of the National Academy of Sciences. "We wanted to experimentally disentangle what exactly makes the difference."

Digital technologies are widely viewed as drivers of efficiency, growth, and innovation. However, their contribution to climate change is significantly greater than previously understood. A new study published in the journal Communications Sustainability shows that digital industries were responsible for about 4.1% of global greenhouse gas emissions in 2021. The bulk of these emissions were not captured by existing emissions accounting standards or official climate assessments.

SÃO MATEUS, Portugal — Winter forced Emanuel Alves to remove his boat from the water at the port of São Mateus in the Azores, the Portuguese archipelago in the North Atlantic Ocean. The 64-year-old fisher expressed concern about the giant network of marine protected areas that permeates the archipelago. “Where are we going to fish now?” he asked. The law establishing the Azores Marine Protected Areas Network was approved in October 2024 and took effect just recently, on Jan. 1 this year. The network now safeguards 30% of Azorean waters, 287,000 square kilometers (110,800 square miles) of seascape sheltering a rich array of marine life. Not two weeks later, on Jan. 15, the Azores Parliament voted to uphold a core provision of the MPA network, after it came under fire in recent months: No fishing inside the fully protected areas, which constitute half the vast network.

The vote effectively killed an earlier move to open these areas to pole-and-line tuna fishing that would have been “catastrophic and damaging to the region,” according to Luís Bernardo Brito e Abreu, coordinator of Blue Azores, a Portugal-based partnership between the Azores regional government, the U.S.-based nonprofit Waitt Institute and the Portugal-based Oceano Azul Foundation that began advocating for the establishment of the MPA network in 2019. “[The] criterion for a total protection area is indeed total protection; there…This article was originally published on Mongabay

Unintentional catch is a big reason that more than a hundred shark species are threatened with extinction. Yet creating a small electric field around fishing hooks using cheap inputs — zinc and graphite — is enough to keep many away, a new study indicates. In coastal waters off Florida, small zinc-and-graphite blocks rigged next to fishing hooks reduced shark catch by around two-thirds, according to the study, which was published in the Canadian Journal of Fisheries and Aquatic Sciences on Jan. 15. “This study was part of an effort to reduce the number of sharks that are caught and killed as incidental bycatch in commercial fisheries,” Stephen Kajiura, a professor of biological sciences at Florida Atlantic University and lead author of the study, told Mongabay. “We’re trying to develop a method that will be cheap and effective that the fishermen could use, that would keep the sharks off the hooks but still allow them to catch their target species.” “It’s no good if it impedes the fisherman’s ability to get what they want,” he added. “And that’s the cool thing about this type of repellent … it only repels sharks and not anything else.” A skipper pulls up longlines after catching a large number of piked dogfish (Squalus acanthias) in waters off Chatham, Massachusetts, in 2009. Unlike other shark species, piked dogfish weren’t deterred by an electric field created around fishing hooks, a new study shows. Image by AP Photo/Stephan Savoia.

ALBUQUERQUE, N.M. — The federal agency that provides health care to Native Americans and Alaska Natives has announced it will phase out the use of dental fillings containing mercury.

The Indian Health Service has used fillings, known as dental amalgams, that contain elemental mercury to treat decayed and otherwise damaged teeth for decades. Native American rights and industry advocates have called for an end to the practice, arguing it exposes patients who may not have access to private dentistry to a harmful neurotoxin.

The use of mercury-containing amalgams, also known as “silver fillings” due to their appearance, has declined sharply since 2009 when the U.S. Food and Drug Administration reclassified the devices from low to moderate risk. The industry has largely abandoned them in favor of plastic resin alternatives, which are also preferred for aesthetic reasons.

The Indian Health Service says it will fully implement the move to mercury-free alternatives by 2027. Already, the percentage of the Indian Health Service’s roughly 2.8 million patient user population receiving them has declined from 12 percent in 2005 to 2 percent in 2023, the latest year of available data, agency documents show.

The U.S. Department of Health and Human Services, which oversees IHS, said growing environmental and health concerns about mercury exposure, and global efforts to reduce materials containing the hazardous heavy metal prompted the change announced this month.

“This is a commonsense step that protects patients and prevents harm before it starts,” Health Secretary Robert F. Kennedy Jr., said in a statement.

The agency’s switch to mercury-free alternatives also upholds legal responsibilities the U.S. government has to the 575 federally recognized tribes, he said.

According to the U.S. Food and Drug Administration, dental amalgam fillings can release small amounts of mercury vapor during placement, removal, teeth grinding and gum chewing. It recommends that certain people at high risk for adverse effects of mercury exposure, including pregnant women, children under 6, and those with existing neurological conditions avoid the fillings. But the administration, along with the American Dental Association, says available evidence does not link mercury-containing fillings to long-term negative health outcomes.

The World Health Organization has created a plan to encourage countries around the world to phase out the use of dental amalgams, citing potential for mercury exposure. In 2013 several countries, including the U.S., signed onto the Minamata Convention, a global agreement targeting the adverse health and the environment effects of mercury. In November, signatories to the convention agreed to phase out the use of mercury-containing dental amalgams by the year 2034.

While Kennedy’s decision to stop its use within the IHS by 2027 puts the U.S. ahead of the global schedule, the country is still behind many other developed nations that have already banned the practice.

“The rest of the world is light years ahead of us,” said Rochelle Diver, the U.N. environmental treaties coordinator for the International Indian Treaty Council, adding that IHS patients should not receive treatment that is considered antiquated by many dentists.

In a statement, the American Dental Association acknowledged declining use of mercury-containing fillings, but said they remain a “safe, durable and affordable material.”

The use of mercury in other medical devices, including thermometers and blood pressure devices, has also declined sharply in recent decades. While mercury-containing amalgams have fallen out of favor in the U.S. private dental sector, patients relying on government services may not have a say, according to Charles G. Brown, president of the World Alliance for Mercury-Free Dentistry.

Many state-administered Medicaid programs continue to cover mercury-containing fillings as a treatment for tooth decay, Brown said.

“If you’re on Medicaid, if you are stuck in the Indian Health Service, if you were stuck in a prison or other institution, you just don’t have any choice,” Brown said.

Artificial intelligence can be used to provide a more precise time of death, which could be crucial in murder investigations. The method was developed by researchers at Linköping University and the Swedish National Board of Forensic Medicine who have trained an AI model on metabolites in thousands of blood samples from real deaths. "Death is a strong biological signal," says Rasmus Magnusson, postdoctoral fellow at the Department of Biomedical Engineering, IMT, at Linköping University, who led the study published in Nature Communications in which AI is used to determine the time of death.

How do plants adapt to drought and heat? New studies on plants of the Canary Islands show that adaptation is not determined by a single character but by the interaction of entire sets of characters. Even closely related plants can follow very different paths.

Conservation has never lacked ideas. Protected areas, payments for ecosystem services, community management, certification schemes, and public campaigns have all been promoted as solutions to biodiversity loss. What has often been missing is reliable knowledge about how well these interventions work, for whom, and under what conditions. A growing body of recent research argues that answering those questions requires moving beyond counting activities to establishing causal impact — determining whether observed outcomes can truly be attributed to conservation actions. Two recent commentaries underscore this shift. One, published on Mongabay by Oxford researcher Tanya O’Garra, warns that conservation risks spending scarce funds on “well-intentioned but ineffective efforts” without stronger causal evidence. Another, published in Nature, argues that biodiversity policy suffers from an “evidence problem,” with many interventions not grounded in robust research. Together with recent methodological papers, they reflect a field attempting to move from persuasion to proof. From monitoring to impact evaluation Traditional conservation monitoring focuses on trends: forest cover, species abundance, or compliance indicators. These metrics are valuable but insufficient. A forest might remain intact because of protection, or because it lies far from roads, markets, or settlements. Distinguishing between these possibilities requires impact evaluation — assessing changes that can be causally attributed to an intervention. Impact evaluation centers on a deceptively simple question: what would have happened without the intervention? Because this counterfactual world cannot be observed, researchers approximate it using comparison groups or statistical techniques. The aim is to rule out alternative explanations for observed outcomes. The…This article was originally published on Mongabay

For those coaxing thirsty crops like alfalfa from the parched fields and withered pasturelands in Eloy, Arizona, water is as good as gold — and just as scarce. “We’ve had nothing from the Colorado River for the last two or three years. I mean, we’ve had to cut back the volumes to the growers and have had to reduce acres and stuff to make it work,” said Ron McEachern, former general manager of the Central Arizona Irrigation and Drainage District, which serves the Eloy area.

The agricultural hub draws from the Colorado River basin through a vast canal network, but drought, overexploitation, and aging irrigation equipment are draining what little remains. “We got gates that are leaking and leaking downstream,” McEachern said. “The water spills and it spills, and nobody’s getting any use out of it.”

Nearly two years ago, the irrigation district was invited to apply to a new non-competitive grant program that the U.S. Department of Agriculture under the Biden administration was launching to help farmers in areas grappling with devastating droughts. McEachern collaborated with the federal agency to identify what his team would do with the grant: replace and upgrade the 35-year-old deteriorating radial arm gates in their local canal system. The district needed the components to more precisely regulate water levels in the canals, but they are much too expensive for them to buy and install on their own.

Then, in late 2024, they got the break they’d been hoping for. The Central Arizona operation was one of 18 irrigation districts spread across 12 western states initially selected to receive up to $15 million each from the USDA. The agency’s [Water-Saving Commodities](https://www.fsa.usda.gov/resources/programs/water-saving-commodities-wsc-program#%3A%7E%3Atext=The+Water-Saving+Commodities+%28WSC%2Cactivities+funded+by+the+grant.%29 program also earmarked grants for three tribal communities and two state associations of conservation districts. In total, the USDA planned to spend a $400 million pool of funds on the initiative.

Gloria Montaño Greene, who served during the Biden administration as Deputy Under Secretary for USDA’s Farm Production and Conservation, told Grist that the idea for the program started back in 2021, as severe drought conditions enveloped agricultural powerhouse states across the country. The $400 million, according to Montaño Greene, was set to be distributed through the Commodity Credit Corporation, a financial institution used to implement specific agricultural programs established by the federal government. By the close of 2024, she said the Biden administration had entered final agreements with selected recipients and notified Congress of how they intended to use the money.

“When we left the administration, we already had the signed agreements and the commitments that were going to be going through with the process,” said Montaño Greene. Based on those final agreements, the money, which was structured to be either reimbursement-based or in the form of advance payments — or both, depending on the agreement — should have started flowing last year, as part of a five-year payment plan. “Everything was done, vetted, and reviewed,” said Montaño Greene. But because this money wasn’t voted on by Congress, the USDA may have the authority to backtrack on its commitments under an earlier administration.

Another former top USDA official familiar with the program, who requested anonymity, confirmed that the agreements were “100 percent” finalized before the end of 2024 — with the expectation that the incoming administration would need to honor them. “I can speak to the assumptions and guidance that we were working on from legal counsel at that time, which was by entering into these agreements with the districts and other partners, we’re committing those dollars to this purpose,” the former official added. “From our perspective, we were operating under a framework and counsel that we were committing those funds to the USDA partners.”

Beginning last January, the Trump administration threw that into a tailspin. Federal monies were frozen, grant programs culled, and an unprecedented number of federal staffers were forced out of work. Many operations at USDA have since resumed to some semblance of normalcy. But the $400 million promised to the irrigation districts, associations, and tribes in 2024 remains unaccounted for, and the grant recipients have received no indication of whether the program would start or the money would be paid out.

In fact, McEachern no longer even knew who at the USDA to ask for help. The last he heard from the agency about the water-saving grant was an email from his former point of contact to let him know they were leaving the USDA. That was over a year ago.

“I think some of the people that were involved are probably no longer there, and nobody was really kind of pushing to get this off the ground,” said McEachern. “One thing is, they haven’t swept the money. So the money is there. It’s just getting them to release it.”

Dan Crabtree, superintendent of Palisade Irrigation District, based in Colorado, one of the other 18 irrigation districts, has had much the same experience. “Since the election, we have not heard anything from USDA, other than to say they were evaluating the program and the application,” said Crabtree. Another recipient — Greybull Valley Irrigation District in Wyoming — told Grist in an email that it also knew nothing about the program’s status.

Randall Winston, general manager of Hidalgo & Cameron Counties Irrigation District 9, in Texas, another of the USDA’s selected recipients, said that while they’ve been waiting, the severe drought in the Rio Grande Valley has only gotten worse. As a result, they have been forced to dramatically reduce how much agricultural land the district is able to irrigate — last year, they supplied water for roughly 8,000 acres, when on a typical year they irrigate 120,000.

“Every drop of water, we’re trying to maximize that and save as much as we can,” said Winston. Prices for the equipment they need to manage the water they do have have also continued to climb, according to Winston, further setting them back. “We are concerned because we need to know the direction to take … We’re not mad at USDA, we just need to find out where we’re at with this,” he said.

Exactly why the administration has kept the funding locked without any communication to grantees for over a year is difficult to discern, according to Food & Water Watch research director Amanda Starbuck. “Is this specifically because it’s intended to help farmers adapt to climate change, and climate change is a bad word in the administration, or it’s simply just trying to cut corners wherever they can?” said Starbuck.

The USDA did not respond to multiple requests for comment.

During one former USDA staffer’s last few months working at the Farm Service Agency, they claim they were forced to partake in information “gatekeeping” as it related to the water-saving program. According to the staffer, who left their role in 2025 and asked to remain anonymous, “I was getting a lot of questions about, like, ‘Can we start or not?’ and I didn’t know the answer. I couldn’t get an answer. I really wasn’t allowed to communicate with them directly. Like, I couldn’t tell them ‘Your grant is frozen. Don’t spend any money because the money may never come to you.’ It was just ‘Tell them it’s under administrative review’ … And then I couldn’t get a clear answer out of my leadership, or my direct manager, or my manager’s manager, about where the program was in the review process.”

As for the suspicion that the program may have been targeted in the way that other Biden-era programs geared toward mitigating climate change have been, the former staffer isn’t convinced. “To me, it does seem pretty neutral from a climate perspective, because a lot of the states that have water problems are not necessarily blue states,” they said. “So I don’t think it was something that someone, like a high level official, would come in and say, ‘That’s the program I want to gut.'”

Although they can’t be certain, the former staffer believes the explanation is actually quite simple: There are no employees left to distribute the money.

Within the first five months of the Trump administration, the Farm Service Agency lost around 24 percent of its federal workforce. “It’s very possible it’s frozen because no one who works there that interacted with the program, like all of the people who know anything about the program, have now left the agency,” they said. The former staffer also said they have “a sinking suspicion” that the internal organizational disarray at USDA may have led the agency to forget about the program, which they described as having “a pretty small footprint” when compared to other initiatives that were dismantled in the last year. “I just don’t understand why we couldn’t be more transparent. … I don’t believe that that is the role that public servants, broadly speaking, both politically appointed and career, should play.”

As the planet continues to heat up, rainfall is becoming increasingly erratic — ushering in longer dry spells punctuated by intense, sudden downpours that can overwhelm the land’s ability to absorb too much water. The resulting whiplash between periods of drought and flood can disrupt farming operations for multiple seasons. Extreme weather fueled by warming already costs the nation’s agricultural industry billions in lost crops and rangeland every year.

Agriculture is not only a victim of this vicious cycle, but one of its drivers. In the U.S., the sector is responsible for at least 80 percent of all water consumed. Crop irrigation, which is often done inefficiently, makes up the single largest share of freshwater withdrawals nationwide. Take alfalfa. The crop used an estimated 2.15 trillion gallons of water across the seven states in the Colorado River basin in 2024 — most of it grown to feed cattle and dairy herds.

“At USDA, we need to do more to also shift production systems to really be lined up with the climate reality,” said Starbuck, who argues that the burden of adaptation shouldn’t fall on individual farmers, or the irrigation districts that support them, but rather to federal regulators.

Yet even as demand for water grows, the policies intended to protect remaining supplies are being systematically dismantled. Over the last year, the administration has aggressively rolled back climate and environmental safeguards — revoking the government’s authority to regulate greenhouse gas emissions, proposing the removal of federal protections from the vast majority of the nation’s wetlands, and holding up billions in conservation efforts.

Together, says Starbuck, these actions are putting at risk the very water supplies that American agriculture depends on.
