Ancient fish fossils with preserved muscle tissue offer a glimpse at how necks evolved in early vertebrate animals. The fossils also offer a puzzle: The fish had specialized abdominal muscles found today in land animals, but not in fish, paleontologists report June 13 in Science. 06.13.13 | more >>

Captive chimps might soon enjoy the same protections that their wild cousins do.

The U.S. Fish and Wildlife Service has proposed to apply the full terms of the Endangered Species Act to all chimpanzees, captive and wild.

An advance in a speedy type of microchip could help engineers integrate computers’ short-term and long-term memory.

For all the recent advances in the speed of computers, their command centers remain relatively inefficient. A central processor does all the thinking and quickly stores a bunch of 1s and 0s on a chip called dynamic random access memory, or DRAM. But DRAM only works when the computer is on, so it can serve only as short-term memory. Data needed for the long haul has to be stored on separate ... 06.11.13 | more >>
