Every spring, raptors return to nesting sites across northern Michigan. The smallest of these birds of prey, a falcon called the American kestrel (Falco sparverius), flies through the region’s many cherry orchards and spends its days hunting for even tinier creatures to eat. This quest keeps the kestrels fed, but it also benefits the region’s cherry farmers.

Fruit farmers have been working symbiotically with kestrels for decades, adding nesting boxes and reaping the benefits of the birds eliminating the mice, voles, songbirds, and other pests that wreak havoc by feeding on not-yet-harvested crops. In addition to limiting the crop damage caused by hungry critters, new research suggests kestrels also lower the risk of food-borne illnesses.

The study, published in November in the Journal of Applied Ecology, suggests the kestrels help keep harmful pathogens off of fruit headed to consumers by eating and scaring off small birds that carry those pathogens. Orchards housing the birds in nest boxes saw fewer cherry-eating birds than orchards without kestrels on site. This translated to an 81 percent reduction in crop damage—such as bite marks or missing fruit—and a 66 percent decrease in branches contaminated with bird feces.

Even as exposure to floods, fire, and extreme heat increase in the face of climate change, a popular tool for evaluating risk has disappeared from the nation’s leading real estate website.

Zillow removed the feature displaying climate risk data to home buyers in November after the California Regional Multiple Listing Service, which provides a database of real estate listings to real estate agents and brokers in the state, questioned the accuracy of the flood risk models on the site.

Now, a climate policy expert in California is working to put data back in buyers’ hands.

The global cost of greenhouse gas emissions is nearly double what scientists previously thought, according to a study published Thursday by researchers at the University of California, San Diego’s Scripps Institution of Oceanography.

It is the first time a social cost of carbon (SCC) assessment—a key measure of economic harm caused by climate change—has included damages to the ocean. Global coral loss, fisheries disruption, and coastal infrastructure destruction are estimated to cost nearly $2 trillion annually, fundamentally changing how we measure climate finance.

“For decades, we’ve been estimating the economic cost of climate change while effectively assigning a value of zero to the ocean,” said Bernardo Bastien-Olvera, who led the study during his postdoctoral fellowship at Scripps. “Ocean loss is not just an environmental issue, but a central part of the economic story of climate change.”

Tencia Benavidez, a Supernatural user who lives in New Mexico, started her VR workouts during the Covid pandemic. She has been a regular user in the five years since, calling the ability to work out in VR ideal, given that she lives in a rural area where it’s hard to get to a gym or work out outside during a brutal winter. She stuck with Supernatural because of the community and the eagerness of Supernatural’s coaches.

“They seem like really authentic individuals that were not talking down to you,” Benavidez says. “There's just something really special about those coaches.”

Meta bought Supernatural in 2022, folding it into its then-heavily-invested-in metaverse efforts. The purchase was not a smooth process, as it triggered a lengthy legal battle in which the US Federal Trade Commission tried to block Meta from purchasing the service due to antitrust concerns about Meta “trying to buy its way to the top” of the VR market. Meta ultimately prevailed. At the time, some Supernatural users were cautiously optimistic, hoping that big bag of Zuckerbucks could keep its workout juggernaut afloat.

Ashley St Clair, the influencer and mother of one of Elon Musk’s children, has sued the billionaire’s AI company, accusing its Grok chatbot of creating fake sexual imagery of her without her consent.

In the lawsuit, filed in New York state court, St Clair alleged that xAI’s Grok first created an AI-generated or altered image of her in a bikini earlier this month.

St Clair claims she made a request to xAI that no further such images be made, but nevertheless “countless sexually abusive, intimate, and degrading deepfake content of St. Clair [were] produced and distributed publicly by Grok.”

US President Donald Trump has announced new tariffs on Nvidia and AMD as part of a novel scheme to enact a deal with the technology giants to take a 25 percent cut of sales of their AI processors to China.

In December, the White House said it would allow Nvidia to start shipping its H200 chips to China, reversing a policy that prohibited the export of advanced AI hardware. However, it demanded a 25 percent cut of the sales.

The new US tariffs on certain chips, announced on Wednesday, were designed to implement these payments and protect the unusual arrangement from legal challenges, according to several industry executives.

The Trump administration on Tuesday proposed a new rule aimed at speeding up and streamlining the permitting process for large energy and infrastructure projects, including oil and gas pipelines and facilities tied to artificial intelligence.

The rule, which does not require action by Congress, includes a suite of procedural changes to section 401 of the Clean Water Act—a law enacted in the 1970s that is the primary federal statute governing water pollution in the United States.

For decades, section 401 has granted states and tribes the authority to approve, impose conditions on, or reject, federal permits for projects that they determine will pollute or damage local waterways.

Older adults can dramatically reduce the amount of ultraprocessed foods they eat while keeping a familiar, balanced diet—and this shift leads to improvements across several key markers related to how the body regulates appetite and metabolism. That’s the main finding of a new study my colleagues and I published in the journal Clinical Nutrition.

Ultraprocessed foods are made using industrial techniques and ingredients that aren’t typically used in home cooking. They often contain additives such as emulsifiers, flavorings, colors, and preservatives. Common examples include packaged snacks, ready-to-eat meals, and some processed meats. Studies have linked diets high in ultraprocessed foods to poorer health outcomes.

My team and I enrolled Americans ages 65 and older in our study, many of whom were overweight or had metabolic risk factors such as insulin resistance or high cholesterol. Participants followed two diets low in ultraprocessed foods for eight weeks each. One included lean red meat (pork); the other was vegetarian with milk and eggs. For two weeks in between, participants returned to their usual diets.

Since 2018, a group of researchers from around the world has crunched the numbers on how much heat the world’s oceans are absorbing each year. In 2025, their measurements broke records once again, making this the eighth year in a row that the world’s oceans have absorbed more heat than in the years before.

The study, which was published Friday in the journal Advances in Atmospheric Science, found that the world’s oceans absorbed an additional 23 zettajoules’ worth of heat in 2025, the most in any year since modern measurements began in the 1960s. That’s significantly higher than the 16 additional zettajoules they absorbed in 2024. The research comes from a team of more than 50 scientists across the United States, Europe, and China.

A joule is a common way to measure energy. A single joule is a relatively small unit of measurement—it’s about enough to power a tiny lightbulb for a second, or slightly heat a gram of water. But a zettajoule is one sextillion joules; numerically, the 23 zettajoules the oceans absorbed this year can be written out as 23,000,000,000,000,000,000,000.

As age-verification laws continue to dismantle the adult industry—and determine the future of free speech on the internet—a Utah lawmaker proposed a bill this week that would enforce a tax on porn sites that operate within the state.

Introduced by state senator Calvin Musselman, a Republican, the bill would impose a 7 percent tax on total receipts “from sales, distributions, memberships, subscriptions, performances, and content amounting to material harmful to minors that is produced, sold, filmed, generated, or otherwise based” in Utah. If passed, the bill would go into effect in May and would also require adult sites to pay a $500 annual fee to the State Tax Commission. Per the legislation, the money made from the tax will be used by Utah’s Department of Health and Human Services to provide more mental health support for teens.

Musselman did not respond to a request for comment.

The writer and comedian Megan Koester got her first writing job, reviewing Internet pornography, from a Craigslist ad she responded to more than 15 years ago. Several years after that, she used the listings website to find the rent-controlled apartment where she still lives today. When she wanted to buy property, she scrolled through Craigslist and found a parcel of land in the Mojave Desert. She built a dwelling on it (never mind that she’d later discover it was unpermitted) and furnished it entirely with finds from Craigslist’s free section, right down to the laminate flooring, which had previously been used by a production company.

“There’s so many elements of my life that are suffused with Craigslist,” says Koester, 42, whose Instagram account is dedicated, at least in part, to cataloging screenshots of what she has dubbed “harrowing images” from the site’s free section; on the day we speak, she’s wearing a cashmere sweater that cost her nothing, besides the faith it took to respond to an ad with no pictures. “I’m ride or die.”

Koester is one of untold numbers of Craigslist aficionados, many of them in their thirties and forties, who not only still use the old-school classifieds site but also consider it an essential, if anachronistic, part of their everyday lives. It’s a place where anonymity is still possible, where money doesn’t have to be exchanged, and where strangers can make meaningful connections—for romantic pursuits, straightforward transactions, and even to cast unusual creative projects, including experimental TV shows like The Rehearsal on HBO and Amazon Freevee’s Jury Duty. Unlike flashier online marketplaces such as DePop and its parent company, Etsy, or Facebook Marketplace, Craigslist doesn’t use algorithms to track users’ moves and predict what they want to see next. It doesn’t offer public profiles, rating systems, or “likes” and “shares” to dole out like social currency; as a result, Craigslist effectively disincentivizes clout-chasing and virality-seeking—behaviors that are often rewarded on platforms like TikTok, Instagram, and X. It’s a utopian vision of a much earlier, far more earnest Internet.

I arrive 10 minutes ahead of schedule from an early morning Eurostar and see Yann LeCun is already waiting for me, nestled between two plastic Christmas trees in the nearly empty winter garden of Michelin-starred restaurant Pavyllon.

The restaurant is next to Paris’s Grand Palais, where President Emmanuel Macron kick-started 2025 by hosting an international AI summit, a glitzy showcase packed with French exceptionalism and international tech luminaries including LeCun, who is considered one of the “godfathers” of modern AI.

LeCun gets up to hug me in greeting, wearing his signature black Ray-Ban Wayfarer glasses. He looks well rested for a man who has spent nearly a week running around town plotting world domination. Or, more precisely, “total world assistance” or “intelligent amplification, if you want.” Domination “sounds scary with AI,” he acknowledges.

Ørsted is seeking a court injunction against the Trump administration’s decision to suspend its work on a major wind farm project off the US northeast coast.

In the latest salvo between the US government and the offshore wind industry, the Danish company filed a legal challenge against the suspension in the US District Court for the District of Columbia on Thursday.

In a statement, Ørsted—the world’s largest offshore wind developer that is 50 percent owned by the Danish state—and its joint venture partner Skyborn Renewables, a unit of BlackRock’s Global Infrastructure Partners, said the US government’s order to suspend the lease on its Revolution Wind project was a violation of applicable law.

Desflurane is a common anesthetic used in hospital operating rooms worldwide. It’s also a climate super pollutant. Now, several decades after the drug was first introduced, a growing number of US hospitals have stopped using the anesthetic because of its outsized environmental impact. On January 1, the European Union went a step further, prohibiting its use in all but medically necessary cases.

Desflurane is more than 7,000 times more effective at warming the planet over a 20-year period than carbon dioxide on a pound-for-pound basis. However, curbing its use alone won’t solve climate change. The anesthetic contributes only a small fraction of total global warming, which is driven by far larger volumes of carbon dioxide and methane emissions.

Still, emissions from the drug add up. Approximately 1,000 tons of the gas are vented from hospitals and other health care facilities worldwide each year. The emissions have a near-term climate impact equivalent to the annual greenhouse gas emissions from approximately 1.6 million automobiles.
