Prehistoric Yukon 'cheetahs' were fish eaters, not really cheetahs at all: study - CP24

A colossal prehistoric snake that lived in India about 47 million years ago may have been one of the largest snakes ever to exist. Known as Vasuki indicus, the ancient reptile could have reached an extraordinary 15.2 meters (50 feet) in length, putting it in the same league as Titanoboa, the enormous extinct snake long regarded as the largest ever discovered. The remarkable discovery, described in 2024 in the journal Scientific Reports, came from fossils unearthed in Gujarat, western India. Researchers estimate that Vasuki measured between 10.9 and 15.2 meters (36 and 50 feet) long, although its exact size remains uncertain. Its enormous body and unusual evolutionary history offer a glimpse into a time when giant snakes inhabited the warm, tropical landscapes of ancient India.

Neanderthals may have used a sticky substance made from tree bark not only to construct tools but also to treat wounds and fight bacterial infections. Scientists have discovered that birch tar, a material commonly associated with prehistoric toolmaking, has antibacterial properties that could have made it useful as an ancient form of medicine. The findings come from a study conducted by researchers at the University of Cologne, the University of Oxford, the University of Liège, and Cape Breton University in Canada. By recreating techniques believed to have been used by Neanderthals, the team produced birch tar and tested its ability to inhibit harmful bacteria.
