Cells from individuals with autism spectrum disorders showed significantly decreased metabolism of the amino acid L-tryptophan, new research shows. The article shows promise for understanding the mechanism of the pathogenesis, as well as developing an ear
New research suggests women can remember faces better than men, in part because they spend more time studying features without even knowing it. And, researchers say a technique can help improve anyone's memories.
Researchers report that a single, 20-minute session of Hatha yoga significantly improved participants' speed and accuracy on tests of working memory and inhibitory control, two measures of brain function associated with the ability to maintain focus and t
Peripheral arterial disease is a common circulation problem in which reduced blood flow can lead to complications that jeopardize the limbs, possibly even requiring amputation. Procedures known as revascularization have reduced the need for amputations 40
A large, multi-center study has found a significant link between lifestyle factors and heart health, adding even more evidence in support of regular exercise, eating a Mediterranean-style diet, keeping a normal weight and, most importantly, not smoking.

A subset of colorectal cancers responds to anti-epidermal growth factor receptor (anti-EGFR) therapies, but develops resistance within months. Among cancers that develop resistance to anti-EGFR therapy, some showed overexpression of a gene called MET, acc
Diseases such as tuberculosis, anthrax, and shigellosis -- a severe food-borne illness -- eventually could be treated with an entirely new and more-effective kind of antibiotic, say scientists who found 46 previously untested molecules that target and dis
Researchers have identified how malaria parasites growing inside red blood cells stick to the sides of blood vessels in severe cases of malaria. The discovery may advance the development of vaccines or drugs to combat severe malaria by stopping the parasi
Highly educated individuals with mild cognitive impairment that later progressed to Alzheimer's disease cope better with the disease than individuals with a lower level of education in the same situation, according to a new study. In the study, neural res
The birth of new neurons in the adult brain sharpens memory in rodents, but whether the same holds true for humans has long been debated. A new study reveals that a significant number of new neurons in the hippocampus -- a brain region crucial for memory

A sensor that relies on reflected light to analyze biomedical and chemical samples now has greater sensitivity, thanks to a carpet of gold nanoparticles. Scientists have determined the ideal size of nanoparticle to improve surface plasmon resonance (SPR)
The act of describing a feeling such as anger may have a significant impact on the body's physiological response to the situation that elicits the emotion, according to new research.

New study indicates overweight and obese patients trust weight-related counseling from overweight physicians more than normal weight physicians and patients seeing an obese primary care physician were more likely to perceive weight-related stigma.
A multi-institutional team of researchers have pinpointed the genetic traits of the cells that give rise to gliomas -- the most common form of malignant brain cancer. The findings provide scientists with rich new potential set of targets to treat the dise
Cytomegalovirus (CMV) infects most middle-aged Americans but usually remains dormant in the body. This study indicates that, in mice, a mouse CMV speeds the progression of an aggressive form of brain cancer when particular genes are shut off in tumor cell
Researchers have come up with a new, mood-boosting therapy for teenagers in drug and alcohol treatment: Shelter dogs. Dog-interaction activities have been found to improve mood among teenagers living in residential treatment centers.
New evidence from research suggests that infants fed formula, rather than breast milk, experience metabolic stress that could play a part in the long-recognized link between formula-feeding and an increased risk of obesity, type 2 diabetes and other condi
