Jymmin: How a combination of exercise and music helps us feel less pain  

Pain is essential for survival. However, it could also slow rehabilitation, or could become a distinct disorder. How strongly we feel it depends on our individual pain threshold. Scientists have discovered that this threshold can be increased by a new fitness method called Jymmin. It combines working out on gym machines with free musical improvisation -- and makes us less sensitive towards physical discomfort.

Computers aid discovery of new, inexpensive material to make LEDs with high color quality  

Computers have helped researchers develop a new phosphor that can make LEDs cheaper and render colors more accurately. Researchers predicted the new phosphor using supercomputers and data mining algorithms, then developed a simple recipe to make it in the lab. Unlike many phosphors, this one is made of inexpensive, earth-abundant elements and can easily be made using industrial methods. As computers predicted, the new phosphor performed well in tests and in LED prototypes.
