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.

Here's a question for all you high school students out there in cyberspace: If it were up to you, would you rather start your school day at 8 a.m. or 8:30 a.m.? (Sorry, noon is not an option.) Sleep in school start time too early If you chose 8:30, you get an A+. According to a new study, students were far more likely to get eight hours of shut-eye at night and were less likely to report being unhappy, depressed, annoyed or irritated when they began their first class at 8:30.

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.

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.

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.

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.

British researchers reported Friday that it may be possible to identify people who are going to develop Type 2 diabetes even before symptoms occur. If the test can be verified, it might be possible to screen people who are at higher-than-normal risk of developing diabetes and intervene before symptoms, and the broad spectrum of complications that accompany them, occur. Triggered by increases in obesity, Type 2 diabetes is becoming a major health problem, with an estimated 285 million people worldwide now affected by the disease -- a number that is expected to grow to 400 million by 2030.

As a parent, I never wished popularity on my children; it takes a lot of work to stay on top. And researchers have come up with a reason I hadn't thought of: Popular kids are more likely to smoke cigarettes, they say. The conclusion, published Wednesday in the Journal of Adolescent Health, is based on surveys among teenagers in ninth and 10 th grades at seven predominantly Latino high schools in the Los Angeles area. It confirms previous studies about high school students in the U.S. and Mexico.

Malaria kills nearly 1 million people a year, but it has a weakness — to infect humans, it needs mosquitoes. In a potential step toward eradicating the disease, researchers report that they have developed a genetically engineered breed of mosquito that cannot be infected by the malaria-causing parasite. Genetically-modified mosquitoes are far from ready for use in the field, but the researchers achieved an unprecedented 100% blockage of the Plasmodium parasite, highlighting the promise of this approach, according to their study.

When in 1950 Dr. Ernst Grafenberg described finding a surprisingly sensitive spot inside the vagina near the urethra, he made the process seem so foolproof. A medical article detailed his effortless demonstrations of the existence of this "distinct erotogenic zone" -- and the not-unexpected consequences of stimulating such a zone -- in his own patients. Anyone with a vagina could surely do the same for herself. Well, perhaps it was that easy for him.
