Common Acne Treatment Stops Blindness in Animal Model

Administering Accutane, a drug commonly used to treat acne, UCLA researchers have successfully stopped the accumulation of toxic pigments in the eyes of animals with a genetic defect similar to Stargardt’s macular degeneration. The UCLA team gave a daily injection of Accutane to mimic the effect of constant light deprivation and the results proved dramatic. These toxic pigments, called lipofuscin, are responsible for the visual loss in patients with Stargardt’s disease.

Freeway living not for the weak of lung

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.
