Science Glance
Members of the Yukagir tribe in Siberia discovered a 9,300-year-old frozen bison mummy complete with all its organs and even some fur.
Details of the necropsy of the animal, which was discovered in 2011, were presented recently at the Society of Vertebrate Paleontology's annual meeting in Berlin. The animal, dubbed the Yukagir bison mummy, is a steppe bison or bison priscus, which went extinct after the Ice Age. Never has a steppe bison mummy been found so complete.

NASA Stumbles Upon A Dead Star That's 10 Million Times Brighter Than The Sun
Think our sun is bright? NASA says its NuSTAR space-based X-ray telescope has detected a dead star that pumps out as much energy as 10 million suns.
"You might think of this pulsar as the 'Mighty Mouse' of stellar remnants," Dr. Fiona A. Harrison, professor of physics and astronomy at the California Institute of Technology in Pasadena and the principal investigator of the NuSTAR mission, said in a written statement.
NASA says it's very close to finding alien life
At a panel discussion on the search for alien life, held this week at NASA's headquarters in Washington, the agency's top scientists said they're getting close.
NASA scientists were joined by leading figures in the fields of astronomy, physics and planetary sciences.
"We believe we're very, very close in terms of technology and science to actually finding the other Earth and our chance to find signs of life on another world," Sara Seager, a physicist at MIT and recipient of the MacArthur Fellowship, told a packed audience on Monday.
Nasa launches satellite to track CO2 in the atmosphere
A rocket carrying a Nasa satellite lit up the pre-dawn skies Wednesday on a mission to track atmospheric carbon dioxide, the chief culprit behind global warming.
The Delta 2 rocket blasted off from California at 2.56 am and released the Orbiting Carbon Observatory-2 satellite in low-earth orbit 56 minutes later, bringing relief to mission officials who lost a similar spacecraft five years ago.
The flight was "a perfect ride into space," said Ralph Basilio, the OCO-2 project manager, at a post-launch press conference.
Bachelor party discovers 3-million-year-old stegomastodon skull fossil
A group of friends in New Mexico didn't set out to discover an ancient stegomastodon skull -- or a fossil of any kind. They were just celebrating their friend's waning days of bachelorhood by taking a hike through Elephant Butte Lake State Park, some 150 miles outside of Albuquerque, N.M.
But along the way, the young men spotted a bone sticking out of the ground. They gathered around it and began digging. The bone turned out to be a tusk, and as they dug further they unearthed a giant elephant-like skull.
Massive 'ocean' found under Earth's surface
Scientists have found evidence of a huge underground reservoir containing up to three times as much water as on the entirety of Earth’s surface and theorized to be the source for all of the world’s oceans.
The new evidence, published Friday in the journal Science, suggests that melting rocks, including those containing the water-rich mineral ringwoodite, may exist far deeper below the Earth's surface. The discovery suggests to researchers that most of the Earth’s water slowly seeped out from within, as opposed to arriving on ice-bearing comets, a theory many scientists have posited.
'Super computer' dupes people into thinking it is a 13-year-old boy
Five machines were tested at the Royal Society in central London to see if they could fool people into thinking they were humans during text-based conversations.
The test was devised in 1950 by computer science pioneer and Second World War codebreaker Alan Turing, who said that if a machine was indistinguishable from a human, then it was "thinking".
No computer had ever previously passed the Turing Test, which requires 30% of human interrogators to be duped during a series of five-minute keyboard conversations, organisers from the University of Reading said.
