Researchers at Washington University School of Medicine in St. Louis and Imperial College London are the first to identify the site where the widely used anesthetic drug propofol binds to receptors in the brain to sedate patients during surgery.

Proton therapy is a cost-effective treatment for pediatric brain tumor patients
Proton therapy, an external beam radiotherapy in which protons deliver precise radiation doses to a tumor and spare healthy organs and tissues, is cost-effective in treating medulloblastomas, fast-growing brain tumors that mainly affect children, when compared to standard photon radiation therapy, according to research presented today at the American Society for Radiation Oncology's 55th Annual Meeting.
