Kepler Telescope Studies Superflares
The Kepler space telescope has provided fresh insight on the colossal explosions that can afflict some stars. These enormous releases of magnetic energy--known as superflares--could damage the atmosphere of a nearby orbiting planet, putting at risk any lifeforms that might reside there.
Astronomers are searching for unseen moons around the planets that the Kepler mission's scientists have discovered. Researchers report that in their quest they have unexpectedly detected a hidden planet--and probably two--by using a technique that promises to aid the search for smaller planets much like Earth.
Researchers have now solidified Vesta's reputation as an archetype for understanding planetary evolution. Dawn, which began orbiting Vesta last July and lowered itself to within 200 kilometres of the asteroid over the following months, has gathered strong evidence that Vesta is indeed the source of the 'Vestoid' family of asteroids as well as the howardite-eucrite-diogenite meteorite family, which accounts for 6% of meteorites.
One of the least expected successes in London's West End last week was Stella by the Take the Space theatre company. The show was about female astronomers--notably the tiny, forgotten, angry Caroline Herschel.

PODCAST & VIDEO: 3D Printing Replacement Body Parts
Regenerative medicine, a fledgling field with the aim of regrowing parts from a person’s own cells, is being amplified with 3D-printing technology, which can now use organic materials to create scaffolds that cells need to grow into their final forms. Richard Wysk, a professor of industrial and systems engineering at North Carolina State University, discusses the latest successes with this research, and the timeline for creating more complicated structures.
