A cave in Israel may have once been a ritualistic gathering site for early humans some 35,000 years ago, likely making it the earliest ritual site in Southwest Asia. The multifaceted research team found the ritualistic evidence in Manot Cave — a famous excavation site in Galilee, Israel. The cave is most notable for the discovery of a 55,000-year-old humanoid skull by a team from Case Western Reserve. The skull helped provide evidence that Homo sapiens and Neanderthals interbred.The cave provi ...read more

While the child escaped with scratches and bites, this has not been the only attack recorded of the incredibly cute river otter.“They’ll protect their mates, they’ll protect their young — they are like humans,” says Carin Wittnich, a senior scientist at the Oceanographic Environmental Research Society, a Canadian charity that focuses on aquatic species research.Otter attacks can occur beca ...read more

Centuries ago, Homo sapiens and varieties of archaic humans lived in their own enclaves throughout different parts of the world. Before we spread to the corners of each continent, our original stomping grounds were in Africa. But as we were evolving there between 200,000 years and 30,000 years ago, who had been occupying the other continents? A few thousand miles north of where our species took shape, another archaic human group called Eurasia home: Neanderthals. From England to Central Asia, N ...read more

Parents of angsty teens have almost certainly heard this line at least once: I didn’t ask to be born.For fish embryos, communication about their impending birth appears quite the opposite. A report in Science details how fish-in-the-making play an active role in determining their delivery.A Fish Embryo Decides When to HatchSuch timing is crucial to baby fish — indeed, to all egg-laying species. Controlling one’s own hatch ensures that the embryo emerges as a newborn, fully developed and re ...read more

Everyday physical activity, like going for a short walk or playing with the kids, may provide short-term benefits for cognitive health, equivalent to reversing four years of cognitive aging. That was a key finding for my colleagues and me in our new study, which was published in the journal Annals of Behavioral Medicine.Prior to enrollment into a study of diet and dementia risk, we asked a diverse sample of 204 middle-aged adults to check in five times per day for a period of nine days via a sma ...read more

As the H5N1 avian flu virus continues to spread in poultry flocks and dairy cattle, consumers may worry about whether the U.S. milk supply is safe to drink. According to the U.S. Food and Drug Administration, the answer is yes, as long as the milk is pasteurized.In late November 2024, however, California regulators recalled two batches of raw, unpasteurized milk from a Fresno dairy farm after bird flu virus was detected in the milk. The dairy subsequently recalled all of its raw milk and cream p ...read more

Child development specialists often evaluate a patient’s ability to complete tasks involving multiple steps. It turns out, many chimpanzees would pass these tests with flying colors, according to a report in the journal PeerJ.“We find objective evidence that wild chimpanzees break down technical tasks into manageable subtasks, and address these subtasks one-by-one, similarly to humans,” says Elliot Howard-Spink, an author of the study. He performed the research while at Oxford, but now is ...read more
