Th Thu, 2 Jul 2009 11:18:19 PST http://www.generef.com/newsstory.rss.html?pid=66942 Researchers at Ben-Gurion University of the Negev have discovered that gene mutations that once helped humans survive may increase the possibility for diseases, including cancer. The findings were recently the cover story in the journal Genome Research.

Some species produce methane with the help of deazaflavin cofactor.

Wed, 1 Jul 2009 13:19:22 PST http://www.generef.com/newsstory.rss.html?pid=66894 The finding suggests that schizophrenia is much more complex than previously thought, and can arise not only from both rare genetic variants but also from a significant number of common ones.

Wed, 1 Jul 2009 10:18:19 PST http://www.generef.com/newsstory.rss.html?pid=66896 A trio of genome-wide studies -- collectively the largest to date -- has pinpointed an array of genetic variation that cumulatively may account for at least one-third of the genetic risk for schizophrenia. One of the studies traced schizophrenia and bipol Wed, 1 Jul 2009 10:18:19 PST http://www.generef.com/newsstory.rss.html?pid=66897 An international research consortium has discovered that many common genetic variants contribute to a person's risk of schizophrenia, providing the first molecular evidence that this form of genetic variation is involved in schizophrenia.

These cells are capable of self-renewal to form new stem cells or differentiate into neurons, astrocytes or oligodendrocytes. The receptors of the Notch family play a significant role in this p Tue, 30 Jun 2009 06:17:26 PST http://www.generef.com/newsstory.rss.html?pid=66788 Visitors can see how their stress levels could affect the heart rate of their unborn baby and find out why pregnant women should reduce their anxiety, at a new exhibit at the Royal Society Summer Science Exhibition, which opens June 30, 2009.
