Our smartphones don't do much when they're sitting there charging overnight, something Samsung and the University of Vienna want to take advantage of to cure diseases. A new app called Power Sleep uses your phone's downtime to crunch protein calculations. That data's used to research cures for diseases, similar to Folding@Home, which was popularized by the PlayStation 3. In this case, Power Sleep — which was backed by Samsung, and made by its former in-house marketing agency Chiel — doubles as an alarm clock designed to replace whatever alarm people were using before. Once set, the app begins grabbing packets of data to crunch, which are about 1MB in size, then sending them back when the process is complete.
