Researchers report that reef-dwelling hogfish have light-sensitive cells embedded in their skin, allowing the animals to sense brightness and adjust their colour without relying solely on eyes. The study, published in Nature, shows this skin-based photoreception can continue to influence colour change even after death. Hogfish live in Atlantic reefs and can shift hues in milliseconds. Those rapid changes aid camouflage, social signalling and may help with temperature regulation and attracting mates.

Scientists presented results from the OPERA study showing artificial intelligence can analyze heart ultrasound scans in about one minute, compared with roughly 30 minutes for trained human experts. The project, led by the University of Glasgow in partnership with AstraZeneca and NHS trusts including Greater Glasgow & Clyde and the Golden Jubilee, demonstrated the AI’s ability to interpret echocardiograms quickly and consistently during a presentation at the European Society of Cardiology conference in Amsterdam.

A new international nature fund set up under the Global Environment Facility aims to help developing countries meet the biodiversity targets agreed at the COP15 summit in Montreal. The fund’s creation was one of the most-contentious issues at those talks, prompting walkouts and repeated negotiations between wealthy and poorer nations.
