A New Nova Just Appeared in the Night Sky – You Can See It with the Naked Eye

We’ve had a Denisovan skull since the 1930s—only nobody knew

A 146,000-year-old skull from Harbin, China, belongs to a Denisovan, according to a recent study of proteins preserved inside the ancient bone.

But the Harbin skull still contains enough of its original proteins to tell a different story: A few of them matched specific proteins from Denisovan bones and teeth, as encoded in Denisovan DNA. So Homo longi was a Denisovan all along, and thank

But when we land in a new time zone, and day suddenly turns to night, this rhythm is
