Psychologists have long known that intelligence, like most other traits, is partly genetic. But a new study led by psychological scientist Christopher Chabris reveals the surprising fact that most of the specific genes long thought to be linked to intelligence probably have no bearing on one's IQ. And it may be some time before researchers can identify intelligence's specific genetic roots. http://medicalxpress.com/news/2012-10-intelligence-genes.html Psychology & Psychiatry Tue, 02 Oct 2012 05:12:46 EST news268373556 (HealthDay)—Middle-aged adults who were born preterm, even moderately preterm (32 to 36 weeks' gestation), are less insulin sensitive compared with adults who were born at term, according to research published in the October issue of Diabetes. http://medicalxpress.com/news/2012-09-insulin-sensitivity-adults-born-preterm.html Diabetes Thu, 27 Sep 2012 18:40:01 EST news267987111 (HealthDay)—For patients undergoing rhinoplasty, the use of porous high-density polyethylene (pHDPE) and expanded polytetrafluoroethylene (ePTFE) implants is associated with increased risk of infection, according to a study published online Aug. 27 in the Archives of Facial Plastic Surgery. http://medicalxpress.com/news/2012-08-phdpe-implant-tied-infection-post-rhinoplasty.html Surgery Tue, 28 Aug 2012 12:25:08 EST news265375496 Researchers, doctors and patients tend to agree that during the high-risk period after an attempted suicide, the treatment of choice is close contact, follow-up and personal interaction in order to prevent a tragic repeat.
