New fossils found in Spain are thought to be of the oldest recorded ancestor of the giant panda. The fossils reveal the origins of this unique bear, as described in a paper published November 14 in the open access journal PLOS ONE by Juan Abella and colleagues from the National Museum of Natural Sciences and the Catalan Institute of Paleontology, Spain.
The two 11.6 million year old fossil jaws and teeth were discovered in southwest Europe and represent a new genus likely to be the oldest known members of the giant panda family. The fossils bear the characteristics of a bear adapted to eating tough plant material like bamboo. The giant panda, native to certain parts of China, is the only living member of this unique bear family with these dietary habits.
Corresponding author Juan Abella adds "The new genus we describe in this paper is not only the first bear recorded in the Iberian Peninsula, but also the first of the giant panda's lineage."

The recent release of Susan Greenfields new book and the film Lucy, both of which are dependent on tired misconceptions or dubious theories about the brain, suggest one worrying conclusion: we are running out of myths about the brain. So here are some new ones, to keep things mysterious
These are the siphonophores, some 180 known species of gelatinous strings that can grow to 100 feet long, making them some of the longest critters on the planet. But instead of growing as a single body like virtually every other animal, siphonophores clone themselves thousands of times over into half a dozen different types of specialized cloned bodies, all strung together to work as a team---a very deadly team at that.
Researchers who study memory have had a thrilling couple of years. Some have erased memories in people with electroshock therapy, for example. Others have figured out, in mice, how to create false memories and even turn bad memories into good ones.
