Apparently men and women are not that different after all. In fact, the sexes are so similar that women have to fight their entire lives just to remain women -- at least on the genetic level.
A new study finds that turning off just one gene, shared by all mammals, turns ovarian cells into testosterone-producing cells found only in the testes -- and this is in adults.

It only takes about 20 minutes after the last time you had sex to become a "virgin" again. That's if you've shelled out $29 for the Artificial Virginity Hymen.
The product has been getting some press, after conservative Egyptian politicians said they want the product banned. They're concerned that brides might use the product to fake their virginity, according to a report by the Associated Press.
A pair of MIT students claim that they have created an algorithm that outs gay members of Facebook by analyzing the sexual orientations of their networks of friends.
The students first analyzed the networks of people who publicized their sexual orientation on Facebook. Turns out that statistically speaking, gay men have more gay friends than straight guys do. So then, they used an algorithm to run the stats on men who kept mum about their sexual orientation on the site. Their computer program was able to correctly identify 10 men whom the students personally knew to be gay in the real world but who hadn't shared that fact on Facebook.
Though the University of Utah in Salt Lake City might not be the first place one would expect to find researchers getting experimental in the bedroom, a team of scientists there have developed a new gel that can quickly shift from liquid to solid, for use in a vaginal condom that more easily protects against both pregnancy and sexually transmitted diseases.
Sex for a female Lake Eyre dragon lizard is sometimes like going to bed with a man and a roaring chainsaw. The male lizard bites her neck before mounting her. If he sinks his teeth in with too much vigor, he can chomp her spinal cord and kill her.
So it's no wonder the lady lizards are choosy about sex.

TV and the movies are full of slapdash -- extremely slapdash -- science. A mystical wave of the hand, a chalkboard full of scribbles, and voila! Cold fusion in every home. That gets no respect from me. But the practitioners of that science... well, sometimes they make it look really good.
So you can keep your wild-haired Wolverine with his tanned muscles and adamantium appendages. My lust objects wear glasses and SPF 45. Knowing how to maim and kill is all well and good, but reciting the digits of pi and lecturing co-eds in dusty classrooms is hot.
Here are 20 fictional scientists I just can't stop watching. Take a look at who excites my atoms.
When it comes to contraception, women have their pick of techniques. In addition to sperm-blocking barriers and foreign objects in the uterus (IUDs), there are about a million ways to pump extra hormones into the bloodstream (pill, patch, ring, shot, or implant).
For men, it's always been pretty much condoms or a vasectomy.
While most people just use Craigslist for finding roommates and discount furniture, there is an undeniably large segment of users that turn to the site for more erotic reasons. With the killing of a masseuse hired through the site dominating tabloid front pages, Craigslist representatives will meet this week with States Attorney Generals from Missouri, Illinois, and Connecticut to work at reducing the number of illegal services offered on the site.
Our sperm and eggs give us one of the greatest responsibilities on the planet: the potential to generate new life, to put forth onto the Earth another living, breathing, thinking, feeling being. Or, they can be sold for a buck.
