However, teasing apart genetic heterogeneity within a biopsied tumor can be difficult. Researchers often fail to tell the difference between a rare variant in a DNA dataset or a small error because of imprecision in existing high-throughput sequencing technologies. http://medicalxpress.com/news/2013-04-rare-mutations-harbored-diverse-populations.html Cancer Wed, 24 Apr 2013 07:30:03 EST news286004541 People born during three major 20th century famines were more likely to develop diabetes later in life than those not born during famines, according to a new study by SFI External Professor Stefan Thurner and collaborators. http://medicalxpress.com/news/2013-03-famine-early-life-linked-diabetes.html Diabetes Wed, 06 Mar 2013 08:05:34 EST news281779528 (Medical Xpress)—There is a long history of research on impaired eye movements associated with schizophrenia. Using a series of simple viewing tests, researchers of a new paper in Biological Psychiatry explored the ability of these eye movement tests to distinguish people with and without the diagnosis of schizophrenia. http://medicalxpress.com/news/2012-10-eye-movements-biomarkers-schizophrenia.html Psychology & Psychiatry Mon, 29 Oct 2012 16:00:03 EST news270744177 Scientists at the Allen Institute for Brain Science reported in the latest issue of the journal Nature that human brains share a consistent genetic blueprint and possess enormous biochemical complexity. The findings stem from the first deep and large-scale analysis of the vast data set publicly available in the Allen Human Brain Atlas. http://medicalxpress.com/news/2012-09-human-brains-genetic-blueprint-enormous.html Neuroscience Wed, 19 Sep 2012 13:43:30 EST news267280952 Aiming to cut expenses and improve care, a 2008 Medicare policy stopped paying hospitals extra to treat some preventable, hospital-acquired conditions – including urinary tract infections (UTIs) in patients after bladder catheters are placed. http://medicalxpress.com/news/2012-09-hospital-acquired-utis-rarely-penalties.html Health Wed, 05 Sep 2012 15:30:03 EST news266077795 (Medical Xpress) -- Whether it's a line from a movie, an advertising slogan or a politician's catchphrase, some statements take hold in people's minds better than others. By applying computer analysis to a database of movie scripts, Cornell researchers have found some clues to what makes a line memorable. http://medicalxpress.com/news/2012-05-youre-gonna-bigger-quote-movie.html Psychology & Psychiatry Tue, 08 May 2012 06:40:01 EST news255676727 Scientists at the Allen Institute for Brain Science have identified similarities and differences among regions of the human brain, among the brains of human individuals, and between humans and mice by analyzing the expression of approximately 1,000 genes in the brain. The study, published online today in the journal Cell, sheds light on the human brain in general and also serves as an introduction to what the associated publicly available dataset can offer the scientific community. http://medicalxpress.com/news/2012-04-fine-scale-analysis-human-brain-yields.html Genetics Thu, 12 Apr 2012 12:00:02 EST news253450709
