(Medical Xpress)—UCLA life scientists have identified a gene previously implicated in Parkinson's disease that can delay the onset of aging and extend the healthy life span of fruit flies. The research, they say, could have important implications for aging and disease in humans. http://medicalxpress.com/news/2013-05-boosting-cellular-garbage-disposal-aging.html Genetics Mon, 06 May 2013 15:00:27 EST news287057425 (Medical Xpress)—Defective viruses, thought for decades to be essentially garbage unrelated to the transmission of normal viruses, now appear able to play an important role in the spread of disease, new research by UCLA life scientists indicates. http://medicalxpress.com/news/2013-02-defective-virus-surprisingly-major-role.html Diseases, Conditions, Syndromes Thu, 28 Feb 2013 18:39:38 EST news281299167 (Medical Xpress)—The drug scopolamine has been used to treat a variety of conditions, including nausea and motion sickness. A new study by UCLA life scientists suggests that it may also be useful in treating anxiety disorders. http://medicalxpress.com/news/2013-02-life-scientists-drug-aid-treatment.html Psychology & Psychiatry Thu, 21 Feb 2013 07:59:32 EST news280655956 Researchers should study how people's social and personal norms are influenced by behavior and use their insights to help governments promote pro-environmental actions, a distinguished group of scholars writes in the March issue of BioScience. The authors maintain that effective policies induce not only short-term changes in behavior but also long-term changes in norms. More effective management of social norms will be necessary, they write, to persuade the public to accept the inconvenience and expense of many environmental policies. http://medicalxpress.com/news/2013-02-scientists-advance-behavioral-norms.html Health Wed, 13 Feb 2013 03:04:28 EST news279947058 Why are older people especially vulnerable to becoming victims of fraud? A new UCLA study indicates that an important clue may lie in a particular region of the brain that influences the ability to discern who is honest and who is trying to deceive us. http://medicalxpress.com/news/2012-12-older-adults-fraud-victims-brain.html Neuroscience Mon, 03 Dec 2012 15:00:14 EST news273755338 (Medical Xpress)—With the ability to sequence human genes comes an onslaught of raw material about the genetic characteristics that distinguish us, and wading through these reserves of data poses a major challenge for life scientists. Researchers at Roswell Park Cancer Institute (RPCI) and the Center for Human Genome Variation at Duke University Medical Center (DUMC) have developed an approach for analyzing data that can help researchers studying genetic factors in disease to quickly cull out relevant genetic patterns and identify variants that lead to particular disorders. http://medicalxpress.com/news/2012-09-approach-efficient-analysis-emerging-genetic.html Genetics Thu, 06 Sep 2012 09:26:47 EST news266142401 Providing support to a loved one offers benefits to the giver, not just the recipient, a new brain-imaging study by UCLA life scientists reveals. http://medicalxpress.com/news/2011-11-tis.html Psychology & Psychiatry Wed, 09 Nov 2011 15:23:35 EST news240074541 UCLA life scientists and colleagues have produced one of the first high-resolution genetic maps for African American populations. A genetic map reveals the precise locations across the genome where DNA from a person's father and mother have been stitched together through a biological process called "recombination." This process results in new genetic combinations that are then passed on to the person's children. http://medicalxpress.com/news/2011-07-life-scientists-technique-genetic-african.html Genetics Sat, 23 Jul 2011 04:03:56 EST news230612619
