Hamsters On Treadmills Provide Electricity Through Use Of Nanogenerators:

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.

Cupid's Arrow May Cause More Than Just Sparks To Fly This Valentine's Day:

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. "This internal elixir of love is responsible for making our cheeks flush, our palms sweat and our hearts race."

Wildlife Salute Valentines Day Of Their Own:

While they might not be giving roses and writing love poems, wildlife have some pretty fascinating - and sometimes downright bizarre - courtship and mating rituals of their own. You won't find singles bars or online dating sites for grizzly bears but our furry and feathered friends have some pretty interesting habits.

Education And Money Attract A Mate; Chastity Sinks In Importance:

This Valentine's Day, researchers at the University of Iowa have some new answers to the perennial question of what men and women want in a partner. Men are increasingly interested in an educated woman who is a good financial prospect and less interested in chastity. Women are increasingly interested in a man who wants a family and less picky about whether he's always Mr. Nice Guy.

Spaniards Prefer Love To Be Passionate, Study Shows:

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.

New Happiness Research Demonstrates When Material Items Are The Best Option:

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.

Talking And Treating Erectile Dysfunction:

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.

When It Comes To Elephant Love Calls, The Answer Lies In A Bone-shaking Triangle:

Many a love-besotted soul has declared they would move the world for their true love, but how many actually accomplish that task in their quest to unite with a lover? Poets and romantics may argue the point, but research has shown that elephants issuing calls, including those of love--more precisely, females in estrus--produce not only audible sounds, but also low-frequency seismic vibrations that can travel through the near-surface soils for distances up to several kilometers.
