That's what a pair of Carnegie Mellon University researchers suspect happened to Antonio Radi?, or "agadmator," a Croatian chess player who hosts a popular YouTube channel. Last June, his account was blocked for "harmful and dangerous" content. YouTube never provided an explanation and reinstated the channel within 2...

 E-Mail IMAGE: The study's findings suggest that decreasing hemispheric temperatures and associated ecological changes were the primary drivers of the Late Quaternary megafauna extinctions in North America. view more  Credit: Hans Sell A new study published in Nature Communications suggests that the extinction of North America's largest mammals was not driven by overhunting by rapidly expanding human populations following their entrance into the Americas. Instead, the findings, based on a new statistical modelling approach, suggest that populations of large mammals fluctuated in re...
