Three scientists awarded Nobel Prize in Physiology or Medicine

The Nobel Assembly at Sweden's Karolinska Institute announced the prestigious award to the three researchers for their pioneering work in developing optogenetics, a field that has transformed modern neuroscience and biomedical research.

Deisseroth, based at Stanford University, developed the foundational optogenetic techniques that enable precise control of neurons using light. Hegemann and Nagel, working at Humboldt University Berlin, made critical early discoveries identifying light-sensitive ion channels in microorganisms that form the basis of the technology.

Optogenetics allows researchers to activate or deactivate specific cells in living tissue with millisecond precision by using light, bypassing the limitations of traditional electrical stimulation methods. This breakthrough has enabled scientists to map neural circuits, understand brain function and develop potential treatments for neurological disorders including Parkinson's disease, epilepsy and blindness.

The technique represents one of the most significant advances in neuroscience over the past two decades, with applications extending beyond basic research into clinical therapy development. The award recognises the transformative impact these discoveries have had on understanding how the brain processes information at the cellular level.

The three laureates will share the monetary prize associated with the award, further cementing their contributions to one of the life sciences' most consequential innovations in recent memory.
