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.

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.

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.

The rich really are different from the rest of us, scientists have found — they are more apt to commit unethical acts because they are more motivated by greed. People driving expensive cars were more likely than other motorists to cut off drivers and pedestrians at a four-way-stop intersection in the San Francisco Bay Area, UC Berkeley researchers observed. Those findings led to a series of experiments that revealed that people of higher socioeconomic status were also more likely to cheat to win a prize, take candy from children and say they would pocket extra change handed to them in error rather than give it back.

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.

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.

African American high school students and boys in low- to middle-income families reported short, fragmented sleep, and that could play a role in their health risks, researchers reported Monday. Anyone who's ever lived with a teenager knows they often don't get the eight to nine hours of sleep the Centers for Disease Control and Prevention recommends. Researchers writing in the journal of the American Academy of Pediatrics looked at one group of young people - those in a lower socioeconomic community.

A 2-million-year old hominid from South Africa had a very unusual diet, an international team of researchers has found. Instead of living on grasses and wild animals from the nearby savannas, like modern humans and pre-humans that have previously been studied, Australopithecus sediba lived on bark, woody tissues, fruits and other plants found almost exclusively in forests, like modern chimpanzees. That diet may be one reason why the species died out, researchers said. A. sediba was first discovered in 2008 in a pit at the Malapa Cave about 30 miles north of Johannesburg.
