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 coral in Australia's Great Barrier Reef is rapidly disappearing due to a host of factors -- all of which are influenced by humans, according to a new study. The report, published in the Proceedings of the National Academy of Sciences, tracks coral cover over the last 27 years and finds levels have fallen by nearly 50%. The Great Barrier Reef is one of the world's most beloved natural attractions because of its remarkable array of sea life. But, according to researchers, a trio of factors has conspired to degrade the reef: tropical cyclones, attacks from the coral predator the crown-of-thorns starfish, and rising water temperatures.

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.

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.

Researchers at De Montfort University, the University of York and Loughborough University in Britain have released a study suggesting that many students with sickle cell disease aren't getting the help they need from their schools. Sickle cell disease is a rare, inherited blood condition - in the U.S., most prevalent in African Americans - that causes sufferers to develop abnormally shaped, "sickled" red blood cells that clog blood vessels and cause complications such as chronic severe pain, organ damage and sometimes stroke.

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.

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.

It's not just what you eat but where and how you eat that seems to affect obesity, say researchers who looked at the effects of family dinner rituals. Families who frequently ate dinner in the kitchen or dining room had significantly lower body mass indices for adults and children, compared with families who ate elsewhere, including in front of the television, the researchers wrote. “Family meals and their rituals might be an underappreciated battleground to fight obesity,” the researchers wrote in the journal Obesity, published Wednesday.
