Southern resident killer whales have been caught on drone video crafting kelp tools to groom one another—an unprecedented behavior among marine mammals. This suggests a deeper social and cultural complexity in these endangered whales than scientists previously realized.

Teen vaping is changing fast — and not in a good way. A large national study found that more adolescents are vaping THC, CBD, and especially synthetic cannabinoids, which are often unregulated and far more dangerous. Even more troubling, many teens don’t know what’s in their vape pens at all. Researchers also found that girls …

Cambridge scientists have spotted gut bacteria that greedily soak up PFAS “forever chemicals,” then ferry them safely out of the body in animal tests, removing up to three-quarters of the toxins within minutes. Their findings hint at probiotic pills that could shield people from PFAS-linked cancers, fertility issues, and heart disease while lawmakers scramble to …

Researchers testing urine from 2- to 4-year-olds in four U.S. states uncovered 96 different chemicals, many of them unmonitored and linked to hormone and brain disruption. Legacy toxins like triclosan are slowly declining, yet replacements such as DINCH plasticizer and modern pesticides are rising. Toddlers—especially the youngest, later-born, and those from minority groups—often carried higher …

In a remarkable twist of science, researchers have transformed a fungus long associated with death into a potential weapon against cancer. Found in tombs like that of King Tut, Aspergillus flavus was once feared for its deadly spores. Now, scientists at Penn and several partner institutions have extracted a new class of molecules from it—called …

Two Ice Age wolf pups once thought to be early dogs have been identified as wild wolves, thanks to detailed DNA and chemical analysis. Surprisingly, their last meals included woolly rhinoceros meat—an unusually large prey item—hinting that ancient wolves might have been bigger than today’s. Their well-preserved bodies also shed light on wolf pack behavior …

Exploration for deep-sea minerals in the Clarion Clipperton Zone threatens to disrupt an unexpectedly rich ecosystem of whales and dolphins. New studies have detected endangered species in the area and warn that mining noise and sediment could devastate marine life that relies heavily on sound. With so little known about these habitats, experts urge immediate …
