What's behind this "geriatrician" shortage?

The human body's immune system is similar to having millions, if not billions, of snipers at the ready aiming and poised to shoot any foreign invader. This is why transplanted tissues and organs are so vulnerable to rejection. But a recent discovery by MIT researchers hopes to make them more viable.

Tyler Sash, a former NFL player, officially died from a drug overdose -- a lethal combination of prescription drugs. But more and more, when it comes to football players succumbing to a surprisingly early death, it seems that brain trauma is often a major contributor.
