The growing ease of DNA sequencing has led to enormous advancements in the scientific field. Through extensive networked databases, researchers can access genetic information to gain valuable knowledge about causative and preventative factors for disease, and identify new targets for future treatments. But the wider availability of such information also has a significant downside—the risk of revealing personal information. http://medicalxpress.com/news/2013-02-privacy-dna-policies-safeguard-identity.html Genetics Thu, 07 Feb 2013 10:51:21 EST news279456671 Using only a computer, an Internet connection, and publicly accessible online resources, a team of Whitehead Institute researchers has been able to identify nearly 50 individuals who had submitted personal genetic material as participants in genomic studies. http://medicalxpress.com/news/2013-01-expose-vulnerabilities-personal-genetic.html Genetics Thu, 17 Jan 2013 14:00:31 EST news277652517 Researchers have shown that transplanting stem cells derived from normal mouse blood vessels into the hearts of mice that model the pathology associated with Duchenne muscular dystrophy (DMD) prevents the decrease in heart function associated with DMD. http://medicalxpress.com/news/2013-01-stem-cell-approach-duchenne-muscular-dystrophy.html Medical research Mon, 14 Jan 2013 13:08:10 EST news277391280 A large-scale analysis of Y chromosomes from more than 20,000 men finds that two spontaneously recurring deletions along a complex region of the Y chromosome are responsible for approximately 8% of cases of failed sperm production. http://medicalxpress.com/news/2012-10-reveals-key-genetic-deletions-contribute.html Genetics Thu, 25 Oct 2012 13:30:01 EST news270389531 New hope has arrived for migraine sufferers following a Griffith University study with the people of Norfolk Island. http://medicalxpress.com/news/2012-06-migraine-female-gene-link.html Genetics Mon, 04 Jun 2012 10:30:51 EST news258024619 The pulse quickens, the heart pounds and adrenalin courses through the veins, but in stressful situations is our reaction controlled by our genes, and does it differ between the sexes? Australian scientists, writing in BioEssays, believe the SRY gene, which directs male development, may promote aggression and other traditionally male behavioural traits resulting in the fight-or-flight reaction to stress. http://medicalxpress.com/news/2012-03-men-aggressively-women-stress-gene.html Genetics Wed, 07 Mar 2012 19:00:01 EST news250359768 A common heart disease which kills thousands each year may be passed genetically from father to son, according to a study led by the University of Leicester. http://medicalxpress.com/news/2012-02-presdisposition-common-heart-disease-father.html Genetics Thu, 09 Feb 2012 04:33:12 EST news247984365 New research presented today at the European Society for Paediatric Endocrinology meeting has found a genetic region, which may control testicle development in the foetus. http://medicalxpress.com/news/2011-09-genetic-region-responsible-testicle.html Genetics Mon, 26 Sep 2011 19:49:41 EST news236285325 (AP) -- Boy or girl?
