McGill University researchers have discovered an effective alternative to pain medication (such as the opiate percocet that Prince was reportedly taking): optogenetics — using light to control cells (such as neurons) in living tissue.

The scientists bred mice that were genetically engineered, causing specific peripheral neurons responsible for pain transmission to express an opsin (light-sensitive protein).
