As such, this story is one in the eye for all those spammers selling erectile dysfunction drugs as scientists have implanted a light-activated gene into rats that makes a protein involved in sexual arousal.

“With this gene in place,” the team reports in the journal Angewandte Chemie, “the rats make a protein involved in the release of the a synthetic designer guanylate cyclase producing a blue-light-inducible surge of the second messenger cyclic guanosine monophosphate (cGMP) in mammalian cells.” With this molecular biology in place, shining a light on the rat’s penis triggers and erection or as the team puts it: “bob游戏手机版 timulated short-circuiting of complex psychological, neural, vascular, and endocrine factors to stimulate penile erection in the absence of sexual arousal.” They suggest that this “may foster novel advances in the treatment of erectile dysfunction.”
