Contact lenses that dispense prescription drugs

Eye diseases like glaucoma could one day be treated by pharmaceuticals delivered through contact lenses. Chemical engineers from the University of Florida say they’ve been able to make soft contact lenses containing tiny embedded particles that slowly release drugs directly where they’re needed. The research was presented today at the 225th national meeting of the American Chemical Society, the world’s largest scientific society, held this week in New Orleans.

Get a little distance from the matter.In case there was any doubt, researchers in — where else? — Los Angeles have determined that living near a freeway exposes you to a lot more pollution than if you lived further away. Specifically, a UCLA team found people who live, work or travel within 165 feet downwind of a major freeway or busy intersection are exposed to potentially hazardous particle concentrations up to 30 times greater than normal background levels.
