A team of Bio-X researchers at Stanford has developed mice whose sensitivity to pain can be dialed up or down simply by shining light on their paws.
The research could help scientists understand and eventually treat chronic pain in humans.
The mice in Scott Delp’s lab, unlike their human counterparts, can get pain relief from the glow of a yellow light.
