From Proust's Madeleines to the overbearing food critic in the movie Ratatouille who's transported back to his childhood at the aroma of stew, artists have long been aware that some odors can spontaneously evoke strong memories. Scientists at the Weizmann Institute of Science have now revealed the scientific basis of this connection. Their research appeared in the latest issue of Current Biology.

HEALTH EDUCATION DESIGNED FOR ADULTS WITH INTELLECTUAL DISABILITIES: AN OPPORTUNITY FOR HEALTHIER LIVES

An Indiana University study involving adults with intellectual disabilities found that the adults increased their personal health knowledge after taking a semi-weekly class for four weeks.

Depression and other emotional symptoms in survivors of torture and other traumatic experiences may be exacerbated by the effects of head injuries, according to a study from the Harvard Program in Refugee Trauma (HPRT), based in the Massachusetts General Hospital (MGH) Department of Psychiatry. In the November 2009 Archives of General Psychiatry, the researchers report finding structural changes in the brains of former South Vietnamese political detainees who had suffered head injuries and clearly link those changes to psychiatric symptoms often seen in survivors of torture.

A strategy that combines gene therapy with blood stem cell therapy may be a useful tool for treating a fatal brain disease, French researchers have found. These findings appear in the 6 November 2009 issue of the journal Science, which is published by AAAS, the nonprofit science society.

Dr. Patrick Aubourg comments on the successful gene therapy trial for the fatal brain disease adrenoleukodystrophy (ALD) as reported in Science. Dr. Aubourg was the leading investigator on this study, and treated two boys with a lentiviral gene therapy. Without treatment these boys would otherwise have faced a fatal prognosis.

Common experience tells us that particular scents of childhood can leave quite an impression, for better or for worse. Now, researchers reporting the results of a brain imaging study online on November 5th in Current Biology, a Cell Press publication, show that first scents really do enjoy a "privileged" status in the brain.

STANFORD, Calif. — A gene associated with longevity in roundworms and humans has been shown to affect the function of stem cells that generate new neurons in the adult brain, according to researchers at the Stanford University School of Medicine. The study in mice suggests that the gene may play an important role in maintaining cognitive function during aging.

Boston – November 5, 2009 – The Autism Consortium, an innovative collaboration of researchers, clinicians, funders and families dedicated to catalyzing research and enhancing clinical care for autism spectrum disorders (ASDs), held its fourth annual symposium on October 28th, 2009, at Harvard Medical School in Boston. The meeting gave scientists, clinicians, advocates and parents an opportunity to gather for the latest information on causes of autism and their implications for diagnosis, prognosis and therapies for people with autism spectrum disorders.

The scientists discovered that the aggressive T-cells overcome the barrier between blood and nerve tissue in a number of steps. Outside the nervous system, the labelled cells moved just as we would expect them to; most cells were floating along with the flow of the bloodstream. Only now and again did a cell attach itself briefly onto the vascular wall. Here they rolled in the direction of the blood stream or were being carried off again by the current. Yet, once the cells reached the blood vessels of the nervous system, they began to act in a completely different manner.

(CHICAGO) -- Rush University Medical Center has opened the Transcranial Magnetic Stimulation (TMS) Clinic to offer patients suffering from major depression a safe, effective, non-drug treatment. TMS therapy is the first FDA-approved, non-invasive antidepressant device-based treatment clinically proven for treatment of depression.

Psychiatrists at Rush University Medical Center were among the first to test the technique and Dr. Philip Janicak, professor of psychiatry and lead investigator at Rush for the clinical trials of TMS, helped to develop this therapy.

Many parents like to meddle in their children's lives. Sometimes this can be beneficial, if the meddling is in the form of parental guidance or setting rules. However, numerous studies have found that in Western countries, when parents are very controlling and dominating over their children, the children suffer psychologically. It has also been suggested that this effect may not be as strong in East Asian countries — researchers have posited that certain aspects of East Asian culture may make children more accepting of their parents' intrusive behavior.

There are areas in the brain devoted to our arms, legs, and various parts of our bodies. The way these areas are distributed throughout the brain are known as "body maps" and there are some significant differences in these maps between left- and right-handed people. For example, in left-handed people, there is an equal amount of brain area devoted to the left and right arms in both hemispheres. However, for right-handed people, there is more cortical area associated with right arm than the left.

Technology is no longer what it used to be: Computers have replaced typewriters and landlines are in rapid decline. Technological advances are being made every day, making many of our lives easier and allowing information to be more accessible and available. However for some people, such as the aging population, technological progress can in fact be more limiting.

In one sense, our hands define our humanity. Our opposable thumbs and our hands' unique structure allow us to write, paint, and play the piano. Those who lose their hands as a result of accident, conflict or disease often feel they've lost more than mere utility.
