Limiting the amount of radiation absorbed in the hippocampal portion of the brain during whole-brain radiotherapy (WBRT) for brain metastases preserves memory function in patients for up to six months after treatment, according to research presented today at the American Society for Radiation Oncology's (ASTRO's) 55th Annual Meeting. The single-arm, phase II study was a multi-institutional, international clinical trial in the U.S. and Canada, conducted through the Radiation Therapy...

Stem cells in the brain remain dormant until called upon to divide and make more neurons. However, little has been known about the molecular guards that keep them quiet. Now scientists from the Salk Institute for Biological Studies have identified the signal that prevents stem cells from proliferating, protecting the brain against too much cell division and ensuring a pool of neural stem cells that lasts a lifetime. The research, which was published in the July 1 issue of Cell Stem Cell,...
