Want to help cure Alzheimer's or breast cancer? From now on, you don't have to do much more than charge your phone. Sony has released a big upgrade to its Folding@Home app for Android that can use your phone's processor for medical research on a continuous basis -- so long as you're on WiFi and charging, you can doze off knowing that you're contributing to a good cause. It also ties into your Google account to both accumulate time on multiple devices as well as earn game-like achievements. The refresh is available now, so give it a shot if you'd like your phone to do more in its idle time than fetch your email.
