Plus: A cyberattack overheated fridges at hundreds of French supermarkets. Open models have real benefits. Do they outweigh the risks? Anthropic recently released a report arguing that a powerful new model released by the Chinese company Z.ai, poses a major cyberattack risk. Its core concern was that it is freely available for anyone to download and modify. The warning was the latest flashpoint in a debate over whether frontier AI models should be open or kept behind the doors of frontier labs.

The technology could strap onto existing gas turbines and make them more efficient--but it wouldn't do away with their emissions entirely. A new company has a plan to make the dirty gas turbines powering data centers more efficient: liquid carbon dioxide. American Supercritical came out of stealth Wednesday, announcing $8 million in funding. It wants to retrofit inefficient gas turbines that many data centers rely on for power with units that can generate more power, without adding more emissions (though the gas-fired turbines will continue to emit carbon pollution). The technology can also theoretically be used on a wide variety of energy sources at a time when power demand is skyrocketing.

Taken from high resolution satellite imagery. Can you tell us a bit about your background and your current area of research? I use computational tools to study animal behaviour. After my PhD, I joined the U.S. Army Research Office, where I used satellite imagery to follow animals across whole landscapes, which is a powerful technique for seeing broad patterns, but far too coarse to capture what individuals are actually doing. That gap is what drives my current work at Princeton: I combine drone video with AI methods to resolve movement at much finer scales, as I have done in studies of Olive Baboons and lions.

For communities living around Naivasha, water is not an abstract resource. It sustains families, livestock, farms and schools. That reality has taken on new significance after plans for a major Microsoft-G42 data centre in Olkaria, near Lake Naivasha, stalled in May 2026 over concerns about available power capacity. Microsoft and United Arab Emirates-based artificial intelligence company G42 announced the project in 2024 as part of a $1bn digital investment package for Kenya. The proposed facility was to run on geothermal energy and eventually scale to as much as 1 gigawatt of capacity.
