Newfound exoplanet may turn to dust: Planet’s dust cloud may explain strange patterns of light from its star

feeds.sciencedaily.com
 Researchers have detected a possible planet, some 1,500 light years away, that appears to be evaporating under the blistering heat of its parent star. The scientists infer that a long tail of debris -- much like the tail of a comet -- is following the planet, and that this tail may tell the story of the planet's disintegration. According to the team's calculations, the tiny exoplanet, not much larger than Mercury, will completely disintegrate within 100 million years. Read more »

A crowning success for crayfish

From:
feeds.sciencedaily.com
 Australian freshwater crayfish have a tooth enamel very similar to humans. Nature sometimes copies its own particularly successful developments. Scientists have now found that the teeth of the Australian freshwater crayfish Cherax quadricarinatus are covered with an enamel amazingly similar to that of vertebrates. Both materials consist of calcium phosphate and are also very alike in terms of their microstructure. This extremely hard substance has apparently developed in freshwater crayfish independently from vertebrates, as it makes the teeth particularly strong. Read more »

 NASA technologists will get a chance next summer to relive the good old days when Agency engineers would affix space-age gizmos to rockets just to see if the contraptions worked. In what will be the first of four high-altitude balloon flights to begin in the summer of 2013, technologists at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif., and Wallops Flight Facility in Wallops Island, Va., are preparing to test new deceleration devices that could replace current descent technologies for landing ever-larger payloads at higher elevations on Mars.
