Adding vegetables to a meal can make you seem a better cook and a better person. A new study found that adding vegetables to the dinner led to more positive evaluations of both the main entree and the cook. Given that vegetables are served with only 23 percent of meals, these results could provide added motivation for parents to serve vegetables with dinner.

A new method of growing cardiac tissue is teaching old stem cells new tricks. The discovery, which transforms aged stem cells into cells that function like much younger ones, may one day enable scientists to grow cardiac patches for damaged or diseased hearts from a patient's own stem cells -- no matter what age the patient -- while avoiding the threat of rejection.

In older adults, antipsychotic drugs are commonly prescribed off-label for a number of disorders outside of their Food and Drug Administration (FDA)-approved indications -- schizophrenia and bipolar disorder. The largest number of antipsychotic prescriptions in older adults is for behavioral disturbances associated with dementia, some of which carry FDA warnings on prescription information for these drugs.

High-resolution real-time images show in mice how nerves may be damaged during the earliest stages of multiple sclerosis. The results suggest that the critical step happens when fibrinogen, a blood-clotting protein, leaks into the central nervous system and activates immune cells called microglia.

A "sonar vision" system that enables people who are blind from birth to perceive the shape of a face, a house or even words and letters, is now being developed. Using this device, the researchers have shown that, in people that are blind from birth, the areas of the cerebral cortex normally devoted to reading become activated in response to stimulation.

Researchers have been studying the cry acoustics of six-month-old infants. At-risk infants produced pain related cries with higher and more variable fundamental frequency (commonly referred to as "pitch") as compared to low-risk infants. A small number of the at-risk infants were later diagnosed with an autism spectrum disorder at 36 months of age.

Physicians should take a serious look at tools and strategies used in behavioral economics and social psychology to help motivate their patients to assert better control over chronic diseases. Breaking large goals into smaller, more manageable parts, for example, may help patients better manage diseases such as diabetes.

"Have you considered how easy it is for us Norwegians to learn English?" asks Jan Terje Faarlund, professor of linguistics at the University of Oslo. "Obviously there are many English words that resemble ours. But there is something more: its fundamental structure is strikingly similar to Norwegian. We avoid many of the usual mistakes because the grammar is more or less the same."

Problems caused by bullying do not necessarily cease when the abuse stops. Recent research shows that victims may need long-term support.

Researchers have identified and “switched off” a chemical chain that causes neurodegenerative diseases such as Huntington’s disease, amyotrophic lateral sclerosis and dementia. The findings could one day be of particular therapeutic benefit to Huntington’s disease patients.

Scientists and business people have known for decades that certain scents -- pine boughs at Christmas, baked cookies in a house for sale -- can get customers in the buying spirit. Researchers have been homing in on just what makes the most commercially inspiring odor. They recently found that a simple scent works best.

What types of public messages will most likely deter drug and alcohol abuse? Negatively framed messages may not be an effective way to reach those most in need of persuasion, a new study suggests. "The findings are somewhat ironic because a whole lot of public service announcements say, 'Drugs are bad for you,' 'Just say no,' or 'This is your brain on drugs' with an image of an egg frying," said researcher Joshua Brown.

A new study proposes an innovative treatment for developmental coordination disorder, a potentially debilitating neurological disorder in which the development of a child's fine or gross motor skills, or both, is impaired. Affecting one in 20 children, predominantly boys, the condition has broad academic, social and emotional impact. It can severely affect reading, spelling and handwriting abilities and lead to problems with self-esteem, obesity and injury.

All patients with Alzheimer's disease lose brain cells, which leads to a shrinking, or atrophy, of the brain. But the pattern of gray matter loss is significantly different in men and women, according to a new study.
