As if there are not enough reasons for obese people to lose weight, a new research report published online in The FASEB Journal (http://www.fasebj.org), adds several more. In a study involving rats, researchers from Duke University found that obesity in mothers causes cellular programming in utero that predisposes offspring to inflammation-related disorders (such as Alzheimer's, Parkinson's, type 2 diabetes, stroke, heart disease, and more) from the day that they are born, regardless of whether or not the offspring are obese themselves.

We know exactly where an object is when we say it is "within the reach of our hand." But if we don't have a hand, can we still see the object just where it is?

Ever get a buzz from eating chocolate? A study published in the open access journal BMC Neuroscience has shown that chocolate-craving mice are ready to tolerate electric shocks to get their fix.

Rossella Ventura worked with a team of researchers from the Santa Lucia Foundation, Rome, Italy, to study the links between stress and compulsive food-seeking. She said, "We used a new model of compulsive behavior to test whether a previous stressful experience of hunger might override a conditioned response to avoid a certain kind of food-– in this case, chocolate".

COLUMBUS, Ohio-- Members of a group or team will work harder when they're competing against a group with lower status than when pitted against a more highly ranked group, according to a new study.

The results run contrary to the common belief that underdogs have more motivation because they have the chance to "knock the higher-status group down a peg," said Robert Lount, co-author of the study and assistant professor of management and human resources at Ohio State University's Fisher College of Business.

Research led by a scientist at Barrow Neurological Institute at St. Joseph's Hospital and Medical Center has opened the door for the advancement of a new category of painkillers, called TRPV1 antagonists.

These drugs block the transient receptor potential vannilloid-1 (TRPV1) channel, which is the same receptor responsible for the sensation of hotness from hot peppers. However, clinical trials have revealed that TRPV1 antagonists cause hyperthermia-– a dangerous, fever-like rise in body temperature.

NEW YORK, N.Y. (February 8, 2010) –- Autism Speaks, the world's largest autism science and advocacy organization, has released its annual list of the 10 most significant research achievements to have impacted autism during the previous year. Each year, Autism Speaks documents the progress made toward its mission to discover the causes and treatment for autism spectrum disorders, and compiles a list of the 10 most significant research achievements to have impacted autism during the previous year.

MBL, WOODS HOLE, MA—The phrase "perk up your ears" made more sense last year after scientists discovered how the quietest sounds are amplified in the cochlea before being transmitted to the brain.

People with anxiety and depression are most likely to use a shade of gray to represent their mental state. Researchers writing in the open access journal BMC Medical Research Methodology describe the development of a color chart, The Manchester Color Wheel, which can be used to study people's preferred pigment in relation to their state of mind.

Use of most electronic media is not associated with headaches, at least not in adolescents. A study of 1025 13-17 year olds, published in the open access journal BMC Neurology, found no association between the use of computer games, mobile phones or television and the occurrence of headaches or migraines. However, listening to one or two hours of music every day was associated with a pounding head.

ST. PAUL, Minn. – A Mediterranean diet may help people avoid the small areas of brain damage that can lead to problems with thinking and memory, according to a study released today that will be presented at the American Academy of Neurology's 62nd Annual Meeting in Toronto April 10 to April 17, 2010.

The study found that people who ate a Mediterranean-like diet were less likely to have brain infarcts, or small areas of dead tissue linked to thinking problems.

High blood pressure appears to predict the progression to dementia in older adults with impaired executive functions (ability to organize thoughts and make decisions) but not in those with memory dysfunction, according to a report in the February issue of Archives of Neurology, one of the JAMA/Archives journals.

A medication previously studied in patients with Alzheimer's disease (latrepirdine) appears well tolerated and may improve thinking, learning and memory skills among individuals with Huntington's disease, according to a report in the February issue of Archives of Neurology, one of the JAMA/Archives journals.

An early stage clinical trial of the experimental drug dimebon (latrepirdine) in people with Huntington's disease appears to be safe and may improve cognition. That is the conclusion of a study published today in the Archives of Neurology.

PASADENA, Calif.—Neuroscientists at the California Institute of Technology (Caltech) and their colleagues have tied the human aversion to losing money to a specific structure in the brain–the amygdala.

A study published online on February 8 in the Journal of Experimental Medicine (www.jem.org) reports that several distinct mutations found in a subset of patients with acute myelogenous leukemia (AML) result in excess production of the same metabolite.
