Most efforts to combat childhood obesity focus on children and adolescents - but perhaps those efforts should start much earlier, even before conception, researchers say. With 10% of U.S. preschoolers obese and another 10% overweight, obesity clearly begins early - in fact, before pregnancy, the researchers say in the June issue of Childhood Obesity. Markers for later heart disease appear in 3-year-olds, they say. A multidisciplinary approach to break the cycle of obesity moving from generation to generation is needed, say the researchers, six experts from institutions across the country who conducted a review of more than 1,000 studies and discussions about efforts underway.

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.

Discriminating against someone for being fat isn't real helpful. That's something scientists have already documented for issues like depression. But a new study says it also seems to make people gain weight. “Rather than motivating individuals to lose weight, weight discrimination increases risk for obesity,” the researchers wrote in an article released Wednesday in the journal PLOS One. It seems logical that calling someone names - or worse - for being fat would discourage them from taking part in gym class or other physical activities, and that happens, the researchers said.

In what is almost certainly a medical first, a physician from my hometown of St. Joseph, Mo., has identified a new viral disease thought to be transmitted by ticks. The virus is related to hantaviruses, which have recently caused at least two deaths at Yosemite National Park, but so far only two confirmed cases have been observed. Because the two farmers who contracted the virus live 60 miles apart, however, researchers from the Centers for Disease Control and Prevention suspect there are probably many more unrecognized cases.

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.

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.

More than two-thirds of common brands of extra-virgin olive oil found in California grocery stores aren't what they claim to be, according to a report by researchers at UC Davis. The findings, which come as the federal government rolls out new standards aimed at cleaning up what has long been a slippery business, highlight mounting concerns over labeling accuracy for olive oil in the U.S. "This is only a beginning, but it's a clear warning," said Dan Flynn, executive director of UC Davis' Olive Center.

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.
