The 2026 Nobel Prize in Medicine has been awarded to three scientists who used light to reveal the mysteries of the brain. Karl Deisseroth, Peter Hegemann and Georg Nagel pioneered the field of optogenetics, a technique that uses tiny lights to activate neurons in the brain. The Nobel Committee said the tool is ushering in a new era in neuroscience. The practice is already being used to develop possible treatments for conditions like blindness, addiction and dementia.
