STANFORD, Calif. — The cells that slough off from a cancerous tumor into the bloodstream are a genetically diverse bunch, Stanford University School of Medicine researchers have found. Some have genes turned on that give them the potential to lodge themselves in new places, helping a cancer spread between organs. Others have completely different patterns of gene expression and might be more benign, or less likely to survive in a new tissue. Some cells may even express genes that could predict their response to a specific therapy. Even within one patient, the tumor cells ...

PULLMAN, Wash.—A new study finds that fetal exposure to the plastic additive bisphenol A, or BPA, alters mammary gland development in primates. The finding adds to the evidence that the chemical can be causing health problems in humans and bolsters concerns about it contributing to breast cancer. "Previous studies in mice have demonstrated that low doses of BPA alter the developing mammary gland and that these subtle changes increase the risk of cancer in the adult," says Patricia Hunt, a geneticist in Washington State University's School of Molecular Biosciences. "Some ...

Philadelphia, PA, May 7, 2012 -- Like their healthy peers, children with disabilities may spend too much time in front of a video screen. For children with cerebral palsy (CP), this leads to an even greater risk of being overweight or developing health issues such as diabetes or musculoskeletal disorders. A group of scientists has found that video games such as Nintendo's Wii offer an enjoyable opportunity to promote light to moderate physical activity in children with CP, and may have a role to play in rehabilitation therapy. Their research is published online today ...

New research provides the strongest evidence to date that psychopathy is linked to specific structural abnormalities in the brain. The study, published in Archives of General Psychiatry and led by researchers at King's College London is the first to confirm that psychopathy is a distinct neuro-developmental sub-group of anti-social personality disorder (ASPD). Most violent crimes are committed by a small group of persistent male offenders with ASPD. Approximately half of male prisoners in England and Wales will meet diagnostic criteria for ASPD. The majority of such men ...

New research indicates that domestic horses originated in the steppes of modern-day Ukraine, southwest Russia and west Kazakhstan, mixing with local wild stocks as they spread throughout Europe and Asia. The research was published today, 07 May, in the journal PNAS. For several decades scientists puzzled over the origin of domesticated horses. Based on archaeological evidence, it had long been thought that horse domestication originated in the western part of the Eurasian Steppe (Ukraine, southwest Russia and west Kazakhstan); however, a single origin in a geographically ...

This nonprofit, 501(c)3 organization relies mostly on volunteer support and donations to perform the daily acts of caring for and rescuing animals. The mission of LAAR is simple—decreasing the overpopulation of domesticated ...

Exercise can counteract muscle breakdown, increase strength and reduce inflammation caused by aging and heart failure, according to new research in Circulation, an American Heart Association journal. The benefits for heart failure patients are similar to those for anyone who exercises: there's less muscle-wasting, and their bodies become conditioned to handle more exercise. Age of the patients didn't matter, either, researchers found. "Many physicians – and insurance companies – still believe that cardiac rehabilitation does not really help in old age. This study clearly ...
