One of the Endeavour astronauts accidentally lost a tool bag during a spacewalk on Tuesday after a grease gun inside the bag exploded. Objects have been lost in space before, but this was one of the largest items ever lost by an astronaut on a spacewalk.

A previously unknown pyramid was found buried under 23 feet (7 meters) of sand last week in Saqqara, Egypt. It is believed to be the tomb of Pharaoh Teti's mother, Queen Sesheshet, who lived 4,300 years ago. This pyramid may be "the most complete subsidiary pyramid ever found at Saqqara," according to Zahi Hawass, secretary general of Egypt's Supreme Council of Antiquities and a National Geographic Society explorer-in-residence. It is considered to be a subsidiary, or satellite, pyramid to the tomb of Teti.

Findings suggests that modern birds, reptiles, and mammals--as well as dinosaurs--shared an early common reptilian ancestor that had claws built from keratin more than 300 million years ago. Keratin evolved into strands of hair only in mammals.
