The gender gap persists in academic medicine, with female physicians who do research earning about $13,000 a year less than their male counterparts, researchers reported Tuesday in the journal JAMA. The coauthors, from the University of Michigan and Duke University's Fuqua School of Business, surveyed 1,729 physician-researchers who received National Institutes of Health grants for career development between 2000 and 2003 -- reasoning that members of that cohort were likely to have similar aptitude and to conduct similar work.

Some popular diets advise against late-night snacking or even eating after 6 p.m. Now, there's some research to confirm that when you eat could matter as well as what you eat if you're trying to shed pounds. A study in Spain followed 420 men and women on a diet for 20 weeks. They were grouped into early eaters -- those who had their main meal before 3 p.m. - and late eaters - those who had it after. (The participants followed the Mediterranean diet, in which the main meal was lunch.)

Something's in the air in Italy -- and that something is cocaine. A study of eight major metropolitan hubs in the country, published this week in the journal Environmental Pollution, has found trace levels of cocaine and cannabanoids from marijuana use. The researchers also monitored the more pedestrian (and legal) drugs of abuse, nicotine and caffeine. The study is a government-sponsored follow-up to a 2006 study in Rome, which found trace elements of cocaine in the air. Why measure atmospheric coke?

Obesity may be declining slightly among preschoolers in low-income families, researchers looking at federal data said. Obesity and extreme obesity in childhood have been associated with other risk factors for heart disease and with premature death . And the condition is likely to continue into adulthood, Dr. Liping Pan of the federal Centers for Disease Control and Prevention wrote. The authors analyzed data from the Pediatric Nutrition Surveillance System, which includes almost half of the children eligible for federal maternal and child health and nutrition programs.

Salvia turned up on the pop culture radar last week after Miley Cyrus, caught on a video using a bong, said she was smoking salvia, not marijuana. So what’s the difference? Researchers at Johns Hopkins University have been looking into that very thing. Little research has been done on the effects of Salvia divinorum , an herb in the mint family that has been used as a hallucinogenic drug. As this Baltimore Sun story explains: "The study, while small and in a tightly controlled environment, appeared to show that the drug could be surprisingly intense and disorienting.

The U.S. Supreme Court decision that Myriad Genetics cannot patent two genes linked to ovarian and breast cancer came as welcome relief to researchers whose work on BRCA1 and BRCA2 genes had been thwarted by legal challenges from the company. But while researchers and clinicians no longer will receive cease-and-desist orders from Myriad, they will have to labor for years to catch up with the data and analysis the Utah-based company has been able to accumulate during the 17 years it held a U.S. monopoly on analyzing the genes, said Eric Topol, director of the Scripps Translational Science Institute in La Jolla.

Scientists have found a new way to study spider webs that literally shines a light on arachnid technology like never before. Using light-scattering technology previously used for studying proteins, collagens and muscle fibers, researchers at Arizona State University measured the strength, elasticity and stiffness of spider webs. Scientists hope what they learn can help them develop new technologies for everyday life. Researchers collected silk from a garden spider, western black widow, orb-weaver spider and green lynx spider.

What makes a corporate merger go bad? Is it a dramatic change in stock price? A revelation about an unprofitable business unit? Resistance from federal regulators? Researchers from the University of British Columbia propose another explanation – too much testosterone . Maurice Levi, Kai Li and Feng Zhang of the university’s Sauder School of Business came up with their theory based on prior research showing that the male sex hormone affects the way men play the ultimatum game . In one version of this game, Player A was asked to divide up $40 between himself and Player B – he could choose either a $35-$5 split, or a $15-$25 split.

Organic produce is more expensive than the conventional variety, and there are many reasons why consumers fork over that extra money. But if one of those reasons is a belief that organic fruits and veggies are healthier, Danish researchers have some bad news. A detailed scientific assessment of carrots, potatoes and onions – some grown conventionally and some grown organically – found that all of the veggies had essentially the same levels of flavonoids and phenolic acids, two types of nutrients that are thought to be helpful in preventing ailments such as heart disease, cancer and dementia.

A mental illness that strikes young children suddenly may be caused by a range of factors, including infections, according to a new report. The paper, published in the journal Pediatrics & Therapeutics, reflects a consensus statement on a condition called Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections -- or PANDAS. PANDAS causes the abrupt onset of obsessive-compulsive symptoms in young children. In many cases, children fell ill after having a simple, childhood streptococcal infection, such as strep throat.
