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.

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.

DNA and RNA molecules are the basis for all life on Earth, but they don't necessarily have to be the basis for all life everywhere, scientists have shown. Researchers at the Medical Research Council in Cambridge, England, demonstrated that six synthetic molecules that are similar to - but not exactly like - DNA and RNA have the potential to exhibit "hallmarks of life" such as storing genetic information, passing it along and undergoing evolution. The man-made molecules are called "XNAs.

Watching television for hour upon hour obviously isn't the best way to spend leisure time -- inactivity has been linked to obesity and heart disease. But a new study quantifies TV viewing's effect on risk of death. Researchers found that each hour a day spent watching TV was linked with an 18% greater risk of dying from cardiovascular disease, an 11% greater risk of all causes of death, and a 9% increased risk of death from cancer. The study, released Monday in Circulation, a journal of the American Heart Assn.

Are the millions of dollars spent to try to reverse childhood obesity a good investment? One answer might be found in the cost if the condition goes unchecked: about $19,000 per obese child in lifetime medical costs, researchers reported Monday. That's $14 billion just for the obese 10-year-olds in the United States, according to researchers at the Duke Global Health Institute and the Duke-NUS Graduate Medical School in Singapore. They reported their results in the journal Pediatrics.

Every time some post-middle-age person tells me he or she had to give up their running habit, I fear a little bit for my future. I've heard many a tale of running woe - people who feel their joints can't take the discomfort any longer. These reports make me wonder whether I'm destined to wear out my knees, ankles or hips and be forced to give up a sport I love. I am dubious of these anecdotes because I believe running fixed my body. As a teen I was clumsier than a baby giraffe on a suspension bridge and broke both my ankles, but after a struggling start I found regular running to be therapeutic for these joints.

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.
