Nepal earthquake offers hints of worse to come
The magnitude 7.8 earthquake that crumbled much of Nepal’s capital city could be overshadowed by larger future earthquakes along the Himalayas, scientists say.

A new ‘spin’ on concussions
Scientists have suspected that rotational forces in the brain may underlie concussions. A new study used athletic mouthguards containing sensors. Data on head movements during collisions suggest that a twisting of the brain may underlie mild brain injuries, including concussion.
