Three scientists, Karl Deisseroth, Peter Hegemann, and Georg Nagel, were awarded the 2026 Nobel Prize in Physiology or Medicine for their groundbreaking work on light-gated ion channels and optogenetics, as announced by the Nobel Assembly at Karolinska Institutet in Stockholm. Optogenetics allows for the precise control of nerve cell activity in the brain, shedding light on its complexities and mysteries according to Thomas Perlmann, the assembly’s secretary general.
The trio, comprising American Deisseroth, and Germans Hegemann and Nagel, expressed their delight and honor in receiving the prestigious award together. They will share the prize amount of 12 million Swedish crowns ($1.7 million Cdn). Deisseroth operates from Stanford University, Hegemann from Humboldt University, and Nagel from the University of Wurzburg in Germany.
Their research in optogenetics holds promise in restoring vision for individuals with retinitis pigmentosa and potentially enhancing cochlear implants to provide more precise stimulation of the auditory nerve. The journey of their discoveries dates back to the early 1990s when Hegemann and Nagel identified channelrhodopsin-2, an ion channel activated by light, through experiments with Chlamydomonas genes.
The Nobel Prizes for chemistry and physics are next in line to be awarded, followed by literature and the peace prize. The prestigious accolades were established by Alfred Nobel, a Swedish chemist and inventor of dynamite, to recognize those who have made significant contributions to humanity. Nobel’s legacy continues to honor exceptional achievements, with the laureates receiving their awards on December 10, marking the anniversary of his passing.
