In recent years, stem cell researchers have become very adept at manipulating the fate of adult stem cells cultured in the lab. Now, researchers at the Salk Institute for Biological Studies achieved the same feat with adult neural stem cells still in place in the brain. They successfully coaxed mouse ...

Researchers have invented a technique in which DNA assays -- the key to personalized medicine -- can be read and evaluated with no need of elaborate chemical labeling or sophisticated instrumentation. Based on electrostatic repulsion that yields images visible to the naked eye, the technique could revolutionize the use of ...

In a breakthrough scientific study, scientists have shown that neural stem cell development may be linked to Autism. The study demonstrated that mice lacking the myocyte enhancer factor 2C protein in neural stem cells had smaller brains, fewer nerve cells and showed behaviors similar to those seen in humans with ...

(University of Montreal) Twenty-one new genetic risk factors associated with Crohn's disease have been discovered, more than doubling the amount of genetic information about the disease. An international consortium of Crohn's disease researchers combined efforts, including major contributions from Canadian researchers -- Dr. John D. Rioux from Montreal Heart Institute ...

(Burnham Institute) In a breakthrough scientific study published today in the PNAS, scientists at the Burnham Institute for Medical Research have shown that neural stem cell development may be linked to Autism. The study demonstrated that mice lacking the myocyte enhancer factor 2C protein in neural stem cells had smaller ...

A new study helps bring scientists closer to a safe and efficient gene delivery method that doesn't involve viruses. Researchers have created a novel synthetic gene vector that packages DNA into well-defined nanostructures that allow it to efficiently deliver genes without triggering immune responses.

Now, in addition to more traditional macrobotanical and archeological remains, scientists are using new genetic and microbotanical techniques to distinguish domesticated maize from its wild relatives as well as to identify ancient sites of maize agriculture. Paleobotanical evidence pushes back the time of domestication.
