Infections Fight To The Death Inside This 3D-Printed Chimpanzee Skull

A research team at the University of Texas, led by chemists Jodi Connell, Marvin Whiteley, and Jason Shear, has 3D-printed this microscopic chimpanzee skull, which later served as an unsettling proof-of-concept for printing "microscopic houses" to trap bacteria, forming "tiny zoos for the study of infections." » 10/07/13 7:58pm 10/07/13 7:58pm

But where in humanity's … » 10/12/12 11:35am 10/12/12 11:35am

What can the DNA of bonobos teach us about what it means to be human?

An international team of researchers has mapped the genome of the bonobo for the first time, revealing that this great ape shares as much DNA with humans as its more aggressive cousin, the chimpanzee. Identifying and understanding how all three genomes overlap, researchers say, could offer new insights into what makes… » 6/13/12 1:21pm 6/13/12 1:21pm

This chimp will kick your ass at memory games — but how the hell does…

This is Ayumu, he's an 11-year-old chimpanzee who lives and trains at Kyoto University's Primate Research Institute. In his time there, Ayumu has come to excel at an incredibly difficult — albeit very straightforward — memorization game. If you challenge him to this game, you will lose. » 2/09/12 12:32pm 2/09/12 12:32pm
