A hard hit to the head typically prompts physicians to look for signs of a concussion based on symptoms such as forgetfulness, wobbly gait and disorientation. But symptoms such as those are subjective, says physiologist Sushmita Purkayastha, Southern Methodist University, Dallas.

A giant star that exploded 30 million years ago in a galaxy near Earth had a radius prior to going supernova that was 200 times larger than our sun, say astrophysicists at SMU. The massive explosion, Supernova 2013j, was one of the closest to Earth in recent years. Analysis of the exploding star's light curve and color spectrum found its sudden blast hurled material from it at 10,000 kilometers a second.

New model allows pharmacological researchers to dock nearly any drug and see how it behaves in P-glycoprotein, a protein in the cell associated with failure of chemotherapy.
New drug-like compounds have low toxicity to noncancerous cells, but inhibit the human protein often responsible for chemotherapy failure
