As debate increases about whether female lacrosse players should wear headgear, a new study reports measurements of the accelerations that stick blows deliver to the head. The study also measured the dampening effect of various kinds of headgear.

PROVIDENCE, R.I. [Brown University] — Lacrosse players swing hard, which is why errant stick blows are the leading cause of concussion in girls’ and women’s lacrosse. In a new study, researchers measured how much the worst blows accelerate the head and how much different kinds of headgear could reduce those accelerations. (more…)

Japan Worst-case Scenario Unlikely to Cause Catastrophic Radiation Release

ANN ARBOR, Mich.— While exposed spent fuel rods at the failing nuclear reactors in Japan pose new threats, the worst-case scenario would still be unlikely to expose the public to catastrophic amounts of radiation, says a University of Michigan nuclear engineering professor who is an expert on this particular kind of reactor.

“For the public, I don’t believe it would be much higher than two additional chest x-rays,” said John Lee, a professor in the Department of Nuclear Engineering and Radiological Sciences, citing the results of the Three Mile Island accident. (more…)
