Giant Fossil Bats Out Of Africa, 35 Million Years Old:
When most of us think of Ancient Egypt, visions of pyramids and mummies fill our imaginations. For a team of paleontologists interested in fossil mammals, the Fayum district of Egypt summons an even older and equally impressive history that extends much further back in time than the Sphinx.

As western states debate removing the gray wolf from protection under the Endangered Species Act, a new study by the Wildlife Conservation Society cautions that doing so may result in an unintended decline in another species: the pronghorn, a uniquely North American animal that resembles an African antelope.

Butterflies and moths are well known for their striking metamorphosis from crawling caterpillars to winged adults. In light of this radical change, not just in body form, but also in lifestyle, diet and dependence on particular sensory cues, it would seem unlikely that learned associations or memories formed at the larval or caterpillar stage could be accessible to the adult moth or butterfly. However, scientists at Georgetown University recently discovered that a moth can indeed remember what it learned as a caterpillar.
