NASA has lost contact with a spacecraft that has orbited Mars for more than a decade. Maven abruptly stopped communicating to ground stations over the weekend. NASA said this week that it was working fine before it went behind the red planet.

Scientists in Britain say ancient humans may have learned to make fire far earlier than previously believed, after uncovering evidence that deliberate fire-setting took place in what is now eastern England around 400,000 years ago. Until now, the oldest confirmed evidence had come from Neanderthal sites in what is now northern France dating to about 50,000 years ago. The discovery was made at Barnham, a Paleolithic site in Suffolk that has been excavated for decades.

By Will Dunham Dec 10 (Reuters) - Scientists have discovered the oldest-known evidence of fire-making by prehistoric humans in the English county of Suffolk - a hearth apparently made by Neanderthals

Archaeologists say they have found the oldest known instance of fire setting, a key moment in human evolution.
