Living near a fracking site appears to be detrimental to infant health, a study eyeing the gas production practice in Pennsylvania suggests. Babies of moms living within one kilometer of a hydraulic fracturing, or fracking, site in the state had a 25 percent greater chance of being born underweight than did babies whose moms lived […]

An astonishing number of things that scientists know about brains and behavior are based on small groups of highly educated, mostly white people between the ages of 18 and 21. In other words, those conclusions are based on college students. College students make a convenient study population when you’re a researcher at a university. It […]

It doesn’t matter if it’s a burly rattler or a tiny garter snake. A deadly fungal disease that’s infecting snakes in the eastern and midwestern United States doesn’t appear to discriminate by species, size or habitat, researchers report online December 20 in Science Advances. The infection, caused by the fungal pathogen Ophidiomyces ophiodiicola, can cover […]

Smell has a reputation as a second-rate human sense. But that assumption stinks once hunter-gatherers enter the picture. Semaq Beri hunter-gatherers, who live in tropical forests on the eastern side of the Malay Peninsula in Southeast Asia, name various odors as easily as they name colors, say psycholinguist Asifa Majid and linguist Nicole Kruspe. Yet […]

A fossil jaw unearthed in Israel is speaking up about when humans departed Africa. The jaw’s message, at least to its finders: That ancient exodus started much earlier than many researchers had assumed. Misliya Cave on Israel’s Mount Carmel has yielded what its discoverers regard as a partial Homo sapiens jaw with an estimated age […]

Dramatic shifts in the East African climate may have driven toolmaking advances and the development of trading networks among Homo sapiens or their close relatives by the Middle Stone Age, roughly 320,000 years ago. That’s the implication of discoveries reported in three papers published online March 15 in Science. Newly excavated Middle Stone Age tools […]

Artificial intelligence is helping draw a more detailed map of the moon. An AI that studied lunar images to learn what craters look like has discovered thousands of new pockmarks on the moon’s surface. This program could also be used to catalog impact scars on other moons or planets, which might improve scientists’ understanding of […]
