A recent study of more than 2,000 identical twins found that medical problems early in life, rather than the neurotoxic effects of anesthesia, are likely linked to an individual's risk for developing learning disabilities. The study's findings, reported in the journal Twin Research and Human Genetics, contradict research published earlier this year, which concluded that receiving anesthesia younger than age four is associated with subsequent learning problems. http://www.physorg.com/news168622940.html Medicine & Health Tue, 04 Aug 2009 17:10:05 EST news168622940 Your mother's wrinkles - or lack there of, may not be the best predictor of how you'll age. In fact, a new study claims just the opposite. The study, involving identical twins, suggests that despite genetic make-up, certain environmental factors can add years to a person's perceived age. Results just published on the web-based version of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons (ASPS), reveal that factors like divorce or the use of antidepressants are the real culprits that can wreak havoc on one's face. http://www.physorg.com/news152884242.html Medicine & Health Tue, 03 Feb 2009 11:51:13 EST news152884242 Scientists at the Centre for Addiction and Mental Health (CAMH) have detected evidence that DNA may not be the only carrier of heritable information; a secondary molecular mechanism called epigenetics may also account for some inherited traits and diseases. These findings challenge the fundamental principles of genetics and inheritance, and potentially provide a new insight into the primary causes of human diseases. http://www.physorg.com/news151507849.html Medicine & Health Sun, 18 Jan 2009 13:30:49 EST news151507849 Homosexual behaviour is largely shaped by genetics and random environmental factors, according to findings from the world`s largest study of twins. http://www.physorg.com/news134052249.html Medicine & Health Mon, 30 Jun 2008 13:44:09 EST news134052249 Homosexual behaviour is largely shaped by genetics and random environmental factors, according to findings from the world's largest study of twins. http://www.physorg.com/news133928602.html Medicine & Health Sun, 29 Jun 2008 03:23:22 EST news133928602
