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.

Astronomers Capture Beautiful Image Of Distant Planets Forming
At the very center of the image above is the sun-like star HL Tau, surrounded by rings of dust and gas. You may never have heard of HL Tau, but this picture will go down in the astronomic annals as the first high-resolution image of the birth of a planetary system.
Using the Atacama Large Millimeter/submillimeter Array (ALMA), an international observatory in northern Chile, scientists were able to capture this image, showcasing the early stages of a planetary system forming around HL Tau—a celestial ultrasound of a distant solar system..
'Odd' rodent-like skull could help crack mystery of when mammals emerged
Scientists have found a complete mammal skull from the time of the dinosaurs – a remarkable find that might offer a window into the dawn of mammals on Earth.
Madagascar, long known for an bizarre assortment of dinosaurs and early mammals, has yielded up another unusual creature – one that could help researchers figure out how long mammals truly have trod the Earth.
An international team of scientists has uncovered a virtually complete skull of an animal they've named Vintana sertichi. Its traits place it within a group of mammals known as Gondwanatheria.
Scientists see mechanism for spontaneous HIV 'cure'
French scientists said Tuesday they had found the genetic mechanism by which two HIV-infected men may have experienced a "spontaneous cure", and said it offered a new strategy in the fight against AIDS.
Both men were infected by the human immunodeficiency virus (HIV), one of them 30 years ago, but never developed AIDS symptoms.
The AIDS-causing virus remained in their immune cells but was inactivated because its genetic code had been altered, the scientists said.
Scientists grow miniature human stomachs from stem cells
Scientists have grown miniature human stomachs from stem cells as a way of studying gastric diseases such as ulcers and stomach cancer and in the future creating tissue to repair patients’ stomachs.
The mini-stomachs are grown in petri dishes from stem cells. Fully formed, they are the size of a pea and shaped like a rugby ball. They are hollow with an interior lining that is folded into glands and pits like a real stomach.
Unmanned NASA-contracted rocket explodes; damage is 'significant'
An unmanned NASA-contracted rocket exploded early Tuesday evening along the eastern Virginia coast, causing a huge fireball but no apparent deaths.
According to NASA, the Orbital Sciences Corp.'s Antares rocket and Cygnus cargo spacecraft were set to launch at 6:22 p.m. ET from the Wallops Flight Facility along the Atlantic Ocean. It was set to carry some 5,000 pounds of supplies and experiments to the International Space Station.
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.
