Cosmic Impacts Might Help Synthesize Organic Compounds
Moffett Field CA (SPX) Dec 14, 2014
Bullets of ice shot at high speeds can deposit organic compounds on surfaces they strike. The new findings suggest that comets might, indeed, have helped deliver key ingredients of life to Earth and perhaps elsewhere, researchers say. The scientists detailed their findings in the journal Astrobiology. Craters on the moon are evidence that the Inner Solar System was prone to giant impacts from asteroids and comets during a tumultuous era, known as the Late Heavy Bombardment, between 4.2 billion to ... read more

Fossils force scientists to rethink 'unusual horrible hand' dino
It's a duck. It's a camel. It's an ostrich. No, it's Deinocheirus mirificus, the duck-camel-ostrich dino. Deinocheirus mirificus translates as "unusual horrible hands." But it's not just the hands of D. mirificus that are strange, its whole body is an odd hodgepodge of awkward features - the nose of a duckbill, the sail-like hump of a camel, the outstretched neck of an ostrich, not to mention the long arms and human-like hands. ... more
