Coral-fringed tropical atolls are among the landforms most threatened by global warming, but many have a potential superpower: Healthy ecosystems may help them keep pace with rising seas.

Atoll islands with native vegetation and thriving seabird populations are “naturally active systems that can change and adapt to their environmental conditions if they are allowed to do so,” said Nick Graham, a marine ecologist at Lancaster University in the United Kingdom, who led an international team of scientists that studied island resilience across 28 atoll islands in the Pacific and Indian oceans.

Their paper, published Wednesday in Science Advances, shows that restoring atoll ecosystems reinforces their growth. Seabirds ferry nutrients from the open ocean and deposit them on the atolls as guano that nurtures land plants, marine life and coral growth. This provides more material for reef building, as parrotfish and other reef feeders turn dead coral into sand to maintain beaches, while native plants with extensive root networks stabilize sediments.

Ukrainian troops have been caught off guard by restrictions on Elon Musk’s Starlink satellite Internet systems that disrupted frontline operations, while Kyiv received no warning from its partners of a Russian missile attack on its energy facilities for the second day running, according to Ukrainian officials.

Starlink terminals used by Ukrainian drone units began experiencing signal failures at speeds above 160 km/h, disrupting several missions early on Wednesday morning, according to military personnel and senior Ukrainian officials.

“Logistics at the frontline and middle strikes are badly limited,” one senior official familiar with the situation on the front told the FT. Ukraine’s middle strikes target Russian military supply lines and logistics. The limitations came with “no warning, just in the middle of the night,” the official said.

When it comes to deciding the fate of the planet, Colleen Golja always thought science and reason would have a seat at the table. That was until one morning last September in London, when the climate researcher took part in the first in a series of war games. The goal: to prevent an uncontrolled global race to develop a technology aimed at cooling the planet but that comes with vast, unknown risks that could reshape life on Earth.

“I thought that would be such an easy thing. Like, we can all agree to do ethical research and make sure it's for the better of all humans,” she told WIRED. “And boy, was I wrong.”

The simulation, titled Exploring Geopolitical Tipping Points and Climate Cooling Strategies, saw a couple dozen foreign-relations experts, scientists, military personnel, and former government officials from across the world convene in a meeting room at Queen Mary University of London. After making introductions over coffee and little yogurts, they sat at tables arranged in a square with the name of the country or organization each person was playing: national governments, climate NGOs and nonprofits, indigenous groups, and tech companies. Golja was assigned to provide technical advice to help participants make scientifically literate decisions.

Donald Trump’s administration has temporarily banned Microsoft, Adobe, and several other tech companies from sponsoring workers for permanent US residency, claiming they abused immigration programs at the expense of American citizens.

Vice-president JD Vance said on Thursday that the H-1B visa programme for highly skilled foreign workers had “become rife with fraud” and that over-reliance on such schemes was “a fundamental insult to the American worker.”

He added that “no company in the US” had “abused this system” more than Microsoft.

If there was a year the world began waking up to climate change, it might have been 1988. That June, the NASA climatologist James Hansen testified to Congress that the climate was warming and would continue to do so as long as humans pumped fossil fuel pollution into the atmosphere. Months later, the United Nations established the Intergovernmental Panel on Climate Change.

And, just weeks before the UN vote, Frank Sprow of Exxon’s corporate research department warned his colleagues in an internal memo, “If a worldwide consensus emerges that action is needed to mitigate against Greenhouse gas effects, substantial negative impacts on Exxon could occur.”

Sprow’s memo is part of a batch of previously undisclosed documents released earlier this year without fanfare as part of an ongoing lawsuit Massachusetts filed against ExxonMobil in 2019. While the memo was quoted in a 2023 article by The Wall Street Journal, it has not been published in full. Several other documents included in the filings are being reported on here for the first time, including more recent statements from Exxon scientists challenging the company’s climate-solution claims about its work on biofuels and carbon capture and storage.

As tensions mount over who gets access to top-end artificial intelligence, French company Mistral has released a new freely available model that it claims can compete with the very best from the US and China.

The new 1 trillion-parameter model, Mistral Large 4—nicknamed Le Chonk—can be used and customized by anyone. It’s currently available in preview, with a final version to follow by the end of the month. Though Le Chonk is built to compete with leading general-purpose models, it’s optimized specifically for coding and cyberdefense, as well as tasks particular to manufacturing, finance, electrical engineering, and other niches.

“There are a lot of areas where the other labs will not focus that much,” Guillaume Lample, cofounder and chief scientist at Mistral, tells WIRED. “There are so many domains in which you can improve models.”
