Could hamsters help solve the world's energy crisis? Probably not, but a hamster wearing a power-generating jacket is doing its own small part to provide a new and renewable source of electricity. And using the same nanotechnology, Georgia Institute of Technology researchers have also generated electrical current from a tapping finger - moving the users of BlackBerry devices, cell phones and other handhelds one step closer to powering them with their own typing.
Getting struck by Cupid's arrow may very well take your breath away and make your heart go pitter patter this Valentine's Day, reports Loyola University Health System love guru Domeena Renshaw, MD. "Falling in love causes our body to release a flood of feel-good chemicals that trigger specific physical reactions," said Domeena Renshaw, MD, author, Seven Weeks to Better Sex, director, Loyola University Health System Sex Clinic and professor, Department of Psychiatry and Behavioral Neurosciences, Loyola University Chicago Stritch School of Medicine.

Spaniards of all ages, in the main, have a "romantic" conception of love. They see it as an irresistible passion, which involves great intimacy and a strong physical attraction, which is classified as "Eros" love. Far fewer of them view the sentiment as a lasting commitment based on closeness, friendship, companionship and affection (amiable or "storge" love), a model which is more common in the north of Europe.
It matters whether you give your loved one a material gift or an experience for Valentine's Day, say researchers at The University of Texas at Austin's McCombs School of Business and Washington University in St. Louis.
The conversation about male sexual dysfunction has grown from a whisper to a roar. From Bob Dole to Mike Ditka, erectile dysfunction, or ED, is no longer hush-hush as more men are talking more openly.
