Researchers at the University of York's Department of Chemistry propose that instead of just tossing old LCD screens, we recycle them for medical purposes. Polyvinyl-alcohol (PVA), a component used as a coating on the glass surfaces of all LCD panels, can also (as it happens) help in the process of regrowing tissue and regenerating body parts. It could even be used to help target specific parts of the body for drug delivery in pills.

Officials in Los Angeles said today that they're going to reconsider a water conservation proposal that won't just ask residents to change their habits, but calls for recycling wastewater, too.
