In two recent reports , Parkinson’s researchers describe findings that may lead to new ways of detecting early signs of the disease and a potential new treatment. In the first...

If you have a big head, you may be subjected to a fair bit of teasing, but science may offer you some consolation. People with smaller heads may be at risk for dementia and other cognitive and mental illnesses. Now, scientists have found associations between common genetic variants and measures of head and brain size.

From your toenails to your hair follicles, every cell in your body contains identical genetic information. But as new research from the University of Edinburgh shows, reality is a little more complicated. DNA in one brain cell can be different from DNA in other brain cells, and from DNA in other tissues, due to the activity of genetic elements called retrotransposons. These elements may play significant roles in human health and cognition depending on where in the DNA and in the brain they are active.
