An international team of researchers has found evidence of Denisovans interbreeding with modern humans in Southeast Asia more recently than thought. The group gave a presentation at this year's meeting of the American Association ...
It's been estimated that the human brain contains roughly 100 billion neurons, together completing countless tasks through countless connections. So how do we make sense of the roles each of these neurons play? As part of ...
