Economics school study finds no link between adult testosterone regimens and financial risk-taking
Darkfrog submitted, created time 11 months 1 week (www.nature.com)
For a while now, researchers have noticed that men and women behave differently in financial situations. In particular, men appear to be much more aggressive in things like day trading, while women tend to take a more sedate tack. To see if the quintessential male hormone, testosterone, was responsible, researchers measured the levels of testosterone in the saliva of male securities traders and found a positive correlation between higher testosterone levels and more risk-taking 
Slightly more girls born to parents in the tropics than to parents in other places

The first global study on human sex ratios reveals that parents are slightly more likely to give birth to female children at tropical latitudes. Researchers have been collecting data for this study for ten years.
The worldwide average is 105 boys for every hundred girls, but this varies a great deal by continent and even by country. In the tropics, the average percentage of male births drops to only 51.1%.
The article takes into account latitude, average temperature and day length, the last of which seems to be most important

Depression affects more than 17 million Americans every year. Depression affects significantly more women than men. In fact, women experience depression twice as often as men and they often experience it earlier, longer, and more severely. Higher rates of depression in women may be linked to biological and social differences.
True depression is more than just the occasional "blues" that most people encounter now and then. Depression affects the whole person -- mind, body, personal life, work life
Gene linked to lupus might explain gender difference in disease risk

In an international human genetic study, researchers at UT Southwestern Medical Center have identified a gene linked to the autoimmune disease lupus, and its location on the X chromosome might help explain why females are ten times more susceptible to the disease than males.
Identifying this gene, IRAK1, as a disease gene may also have therapeutic implications, said Dr. Chandra Mohan, professor of internal medicine and senior author of the study. "Our work also shows that blocking IRAK1 action shuts down lupus in an animal model
Plant Biologists Discover Gene That Switches On "Essence of Male"

Biologists at the University of Leicester have published results of a new study into plant sex--and discovered that a particular gene switches on "the essence of male." The study takes to a new level understanding of the genes needed for successful plant reproduction and seed production.
Unlike animal cells, in which the female body nourishes the growing embryo, plant species require two sperm cells for fertilization--one provides genetic material and the other develops into the nutrient-rich endosperm.
Men control appetite better than women

Men have a better ability to suppress their hunger than women when presented with food.
Male and female study participants fasted for eighteen hours, and then got to see and smell their favorite foods. For the following thirty minutes, participants filled out surveys about their feelings of hunger and, while linked up to brain imaging equipment, attempted to stop thinking about food.
Men showed less hunger-related brain activity than women did. Researchers suspect that the female sex hormones, already linked to weight gain, may have something to do with this.

Men get more relief than women do from painkillers like morphine, according to some studies. New research with rats hints at a possible explanation: Male rats have more receptors for the drug in a brain region involved in pain processing. Although it's not yet clear whether the same is true in humans, researchers say the study underscores the need for more research on the sex-specific effects of pain drugs
DSM-IV gets reexamined. Expect a DSM-V in a few years.
Darkfrog submitted, created time 1 year 3 months (www.nytimes.com)
Psychologists are revising the DSM-IV. The Diagnostic and Statistical Manual of Mental Disorders has been altered a few times since its first edition came out in 1952 (hence the "IV") to reflect better information and changing ideas about what makes a healthy mind. For example, earlier versions of the DSM listed homosexuality as a disease. The DSM-IV does not
Stem cells from testicles offer an alternative to embryos
jerry submitted, created time 1 year 5 months (ap.google.com)
Cells taken from men's testicles seem as versatile as the stem cells derived from embryos, researchers reported Wednesday in what may be yet another new approach in a burgeoning scientific field. The downside? Because of their source, these cells could only be used for regenerative medicine in male patients, not in female ones.
The study involved twenty-two samples from men aged seventeen to eighty-one. All of them men were undergoing treatments for other reasons
Female physicians most effective at treating childhood asthma

Female physicians have a better perception of asthma symptoms in children than their male counterparts, according to Turkish researchers.
The finding could indicate significant contribution of gender-related factors in clinical attitudes and beliefs,Bulent Sekerel (Hacettepe University Faculty of Medicine, Ankara, Turkey) and colleagues explain in the journal BMC Health Services Research.
Understanding the level of management ability of physicians may guide interventions to improve quality of care and patient outcomes,?the authors write
German professor in sex discrimination battle
sea-maid submitted, created time 1 year 7 months (www.nature.com)
A local government investigation over the appointment of a German university’s director is highlighting women’s struggle to reach top academic positions in the country...
Ordinarily, gender discrimination can be very hard to show, but in this case the woman at the center of the lawsuit made the appointment committee's final cut and the man who was eventually selected for the position did not.

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
Exposure to PCBs decreases likelihood of giving birth to boys
kavin submitted, created time 1 year 8 months (www.ehjournal.net)
Women exposed to high levels of PCBs (polychlorinated biphenyls - a group of banned environmental pollutants) are less likely to give birth to male children.
A study published today in BioMed Central's open access journal Environmental Health found that among women from the San Francisco Bay Area, those exposed to higher levels of PCBs during the 50s and 60s, were significantly more likely to give birth to female children

What makes people gay? Biologists may never get a complete answer to that question, but researchers in Sweden have found one more sign that the answer lies in the structure of the brain.
