Researchers at UC Berkeley have identified a nearly complete museum skull as Adelphailurus kansensis, an early saber-toothed cat that lived in North America more than 5 million years ago. The discovery, described in the Journal of Vertebrate Paleontology, gives scientists a rare look at a little-known branch of the cat family before saber teeth reached…

Researchers at UT Austin have reported fossilized microbial wrinkle structures in 180-million-year-old deep-water rocks from Morocco, pointing to ancient life that may have flourished in darkness. The finding, described in a study in Geology, suggests that some microbial communities left traces in places where scientists have rarely expected them to survive or fossilize. The discovery…
Researchers supported by the National Institutes of Health have triggered sleep’s restorative effects in selected parts of the awake mouse brain. The animal study, published in Nature Neuroscience, suggests that carefully timed sleep-like activity can help recalibrate neural connections and protect memory after sleep loss. The work offers a rare look at what sleep may…
Researchers at Kyushu University have developed a solid molecular material that converts visible sunlight into ultraviolet light under natural outdoor conditions. Reported in Nature Communications, the material reached a visible-to-UV conversion efficiency of 1.9%, showing that ordinary sunshine can be transformed into higher-energy light with a carefully designed solid. The result points to a practical…
