Scientists have caught tiny amounts of a strangely shaped protein — a relative of a well-known suspect in Alzheimer’s disease — spreading destruction throughout the brains of mice. If a similar process happens in the human brain, it could help explain how Alzheimer’s starts, and even suggest new ways to stop the dangerous molecule’s spread. Rudy Tanzi, the Joseph P. and Rose F. Kennedy Professor of Neurology
at Massachusetts General Hospital, is quoted.
