Is marital infidelity up or do we just talk about it more?
Darkfrog submitted, created time 3 weeks 4 days (www.nytimes.com)
Studies over the past few decades have shown married women closing "the infidelity gap." Female cheaters don't outnumber male ones just yet, but they're getting there. The question, though, is this: Are women cheating (proportionately) more than they did or are they just more willing to admit it on an anonymous survey? This study suggests the latter.
It also chronicles changes in the rate of marital infidelity, also called adultery in more archaic settings. Aside from more young married women cheating on their partners, the most striking result is that more older people are involved 
Yeast reveals sexual selection in action

The yeast microbe provides way to track evolution gene by gene.
Sexual selection is difficult to work with in complex species. Scientists dispute over whether sexually favored traits represent side effects of healthy immune systems or other desirable traits or whether these preferences arise arbitrarily. One of the reasons that this is so difficult to figure out is that the traits involve multiple genes.

Although circumcision has been shown to reduce rates of HIV transmission among heterosexual couples, circumcision offers little HIV protection to gay/bisexual men -- overall. But it might cut HIV risk in predominantly insertive partners.

Studies have shown that social networking is a risk factor for catching a sexually transmitted disease (but only real-world social networking; LinkedIn is okay). However, this seems to be more of a result of an understanding of what a social network is than any Internet-induced change in the way people choose sexual partners. Sexually transmitted diseases are by definition (usually) transmitted along intimate social networks.

ONE of the biggest mysteries of HIV is why the virus spreads so readily via heterosexual sex in Africa but not elsewhere. A study in monkeys suggests parasitic worms may be to blame.

For both men and women, sexual problems are a common side effect of antidepressants. Viagra and similar drugs have long been prescribed to men in this situation. Now a study suggests Viagra may help women as well.
The study looked at ninety-eight premenopausal women with major depression who started to have sexual problems after going on a popular class of antidepressants that includes drugs such as Zoloft and Prozac. The women were randomly assigned to receive either Viagra or a placebo for eight weeks

There's no real difference between the scores of U.S. boys and girls on common math tests, according to a massive new study. Educators hope the finding will finally dispel lingering perceptions that girls don't measure up to boys when it comes to crunching numbers.
"This shows there's no issue of intellectual ability--and that's a message we still need to get out to some of our parents and teachers," says Henry "Hank" Kepner, president of the National Council of Teachers of Mathematics in Reston, Virginia.
It won't be a new message

Three Kinds of Drugs That Can Kill Your Sex Drive
If you're having sex drive issues, check your medicine cabinet. Several varieties of prescription medication can dampen desire.
Birth control:
Some hormonal birth control methods such as pills and patches can increase women's levels of sex-hormone-binding globulin (SHBG), which drops the amount of testosterone that's floating around freely in the bloodstream
Sexual Arousal Dependent on Flow of Potassium Ions in Brain Cells

When it comes to sex, a female rat knows how to avoid a communication breakdown. To announce her sexual readiness, she will automatically arch her back, deflect her tail and stand rigid to allow an aroused male to mount. Now, Rockefeller University researchers have figured out the precise chemical and physical mechanism in a group of brain cells that controls this swayback posture, a reflex called lordosis that signals one of life’s most complex yet primitive instincts—the need for sex
Erections: Use 'Em or Lose 'Em--------Frequent Sex Protects Against Erectile Dysfunction

July 3, 2008 — Men who don't use their erections lose them, Finnish researchers find.
Aging men who have sex at least once a week have only half the risk of developing erectile dysfunction as do men who have sex less often.
But once-a-weekers shouldn't gloat. More sex means even less ED risk. Men who have sex at least three times a week are only one-fourth as likely to get erectile dysfunction as are men who have less-than-weekly sex

The adaptive function of copulation calls in female primates has been debated for years. One influential idea is that copulation calls are a sexually selected trait, which enables females to advertise their receptive state to males. Male-male competition ensues and females benefit by getting better mating partners and higher quality offspring. We analysed the copulation calling behaviour of wild female chimpanzees (Pan troglodytes schweinfurthii) at Budongo Forest, Uganda, but found no support for the male-male competition hypothesis
Homosexual couples shed light on power sharing in relationships
Darkfrog submitted, created time 5 months 1 week (www.nytimes.com)
When Vermont legalized gay marriage, psychologists jumped on the opportunity to study human relationships. About a thousand heterosexual and homosexual couples participated in a study on relationships.
In general, homosexual relationships were more egalitarian, whereas in heterosexual ones the women got a disproportionate amount of the housework (and initiating conversations about relationship upkeep) and the men got a disproportionate amount of the financial responsibility. In addition, the homosexual couples argued better

Malaysia's deputy health minister urged every woman in the country to carry a condom to protect against HIV, the virus that causes AIDS, and declared that this is not to debase them but to protect them. Women are the first ones to get exploited by their (HIV-positive) partners.

The results reported here provide direct evidence for an essential function for N(6)-methyladenosine in a multicellular eukaryote, and the interaction with At FIP37 suggests possible RNA processing events that might be regulated or altered by this base modification.

Birds and bees may do it, but the microscopic animals called bdelloid rotifers seem to get along just fine without sex, thank you. What's more, they have done so over millions of years of evolution, resulting in at least 370 species.
