Researchers in the laboratory of Samuel I. Stupp at Northwestern University have an interesting approach for tackling some major health problems: gather raw materials and then let them self-assemble into structures that can address a multitude of medical needs.

A recently discovered signaling system in the brain has just been shown to be turned on by methamphetamine, an Oregon Health & Science University study found.
The signaling system could soon become a target for therapies aiming to reverse meth's adverse health effects as well as reduce the craving that drives its abuse.
