AI provides a more precise time of death post-mortem

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

How Japanese medical trainees view AI in medicine

Artificial intelligence (AI) is rapidly transforming health care and medical education. From enhancing diagnostic accuracy and clinical decision-making to enabling virtual simulations and personalized learning, AI technologies are becoming embedded in the daily practice of

Kelp: The planet's other forest crisis

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.

Space lasers reveal oceans rising faster than ever

A new 30-year analysis reveals that melting land ice is now the main force behind rising global sea levels. Researchers discovered that oceans rose about 90 millimeters since 1993, with most of the increase coming from added water mass rather than just warming expansion. Ice

Training harder could be rewiring your gut bacteria

Training harder may do more than build muscle—it could transform your gut. Researchers found that intense workouts change the balance of bacteria and important compounds in athletes’ digestive systems. When training loads dropped, diet quality slipped and digestion slowed,

Image: Curiosity rover surveys boxwork region of Mars

NASA's Curiosity Mars rover captured this panorama of boxwork formations—the low ridges seen here with hollows in between them—using its Mastcam on Sept. 26, 2025, the 4,671st Martian day (sol) of the mission. These boxwork formations were created billions of years ago when

Phosphoric acid dimers reveal nature's proton highway

Whether in our bodies or in fuel cells, phosphoric acid plays an important role in many chemical processes because it is exceptionally good at transporting charges. Researchers from the Department of Molecular Physics at the Fritz Haber Institute gained new molecular insights
