Physicists Go Small: Let's Put A Particle Accelerator On A Chip

By Joe Palca
An early prototype of the silicon-chip-sized particle accelerator that physicists at Stanford are working on. Eventually, miniature accelerators might have a role in radiating tumors, the scientists say.

A tiny accelerator could be useful in medicine as well as basic science. Instead of speeding up beams of electrons through giant tunnels, the aim here is to build accelerators on semiconductor chips.

Scientists Hunt For A Test To Diagnose Chronic Brain Injury In Living People

By Tom Goldman
UCLA researchers are using a radioactive tracer, which binds to abnormal proteins in the brain, to see if it is possible to diagnose chronic traumatic encephalopathy in living patients. Warmer colors in these PET scans indicate higher concentrations of the tracer.

Doctors are closer to a test in live brains that could help diagnose chronic traumatic encephalopathy, a disease that's been linked to concussions and other repeated brain assaults.
