Tiny CREPT instrument to study the radiation belts Posted: 15 Feb 2013 04:42 PM PST A smaller version of an instrument now flying on NASA's Van Allen Probes has won a coveted spot aboard an upcoming NASA-sponsored Cubesat mission -- the perfect platform for this pint-size, solid-state telescope.

Hubble sees cosmic 'flying v' of merging galaxies Posted: 15 Feb 2013 04:39 PM PST The Hubble Space Telescope has taken an image of a large "flying V" that is actually two distinct objects -- a pair of interacting galaxies known as IC 2184.

Russian asteroid strike: Numerous injuries, significant damage Posted: 15 Feb 2013 04:21 PM PST A space rock a few metres across exploded in Earth's atmosphere above the city of Chelyabinsk, Russia today (Feb. 15, 2013) at about 03:15 GMT. The numerous injuries and significant damage remind us that what happens in space can affect us all.

Russia meteor not linked to asteroid flyby, preliminary data indicate Posted: 15 Feb 2013 04:17 PM PST Preliminary information indicates that a meteor in Chelyabinsk, Russia, is not related to asteroid 2012 DA14, which is flying by Earth safely today.

Breakthrough in ovarian cancer: Selumetinib Posted: 14 Feb 2013 04:41 PM PST Researchers have discovered that many women with low-grade serous carcinoma of the ovary or peritoneum have seen their tumors stabilize or shrink after taking a regular dose of the compound selumetinib.

Supernova remnants produce cosmic rays Posted: 14 Feb 2013 04:41 PM PST A new study reveals the first clear-cut evidence the expanding debris of exploded stars produces some of the fastest-moving matter in the universe. This discovery is a major step toward understanding the origin of cosmic rays, one of Fermi's primary mission goals.

Clues to the mysterious origin of cosmic rays Posted: 14 Feb 2013 11:18 AM PST Very detailed new observations of the remains of a thousand-year-old supernova have revealed clues to the origins of cosmic rays. For the first time the observations suggest the presence of fast-moving particles in the supernova remnant that could be the precursors of such cosmic rays.

Humans and chimps share genetic strategy in battle against pathogens Posted: 14 Feb 2013 11:16 AM PST A search for long-lived balancing selection has found at least six regions of the genome where humans and chimpanzees share a combination of genetic variants. These human genetic variation dates back to a common ancestor with chimpanzees millions of years ago, before the species split.

Near-Earth asteroid makes preview appearance Posted: 14 Feb 2013 08:11 AM PST Like trailers for the coming attraction, new images show asteroid 2012 DA14 on its way to a record-close approach to Earth on Feb. 15. One image, taken by amateur astronomer Dave Herald of Murrumbateman, Australia, on Feb. 13, shows the asteroid as a tiny white dot in the field of view. Another set of animated images, obtained by the Faulkes Telescope South in Siding Springs, Australia, on Feb. 14, and animated by the Remanzacco Observatory in Italy, shows the asteroid as a bright spot moving across the night sky.
