Researchers Karl Deisseroth, Peter Hegemann, and Georg Nagel received the 2026 Nobel Prize in Medicine for their work on optogenetics, a technique that uses light to control individual neurons. Their discoveries, rooted in microbiology research on algae, enable precise mapping and study of living brains, advancing understanding of neurological functions and diseases.
Henri Kagan and Kenso Soai received the Nobel Prize in Chemistry for discovering how certain reactions can favor the formation of one mirror-image form of a molecule over the other. Their work sheds light on how biological systems might have developed a preference for specific molecular handedness, despite initial conditions producing equal amounts of both forms. This breakthrough advances understanding of the origins of life's molecular asymmetry.
University of Wisconsin-Madison physicist Francis Halzen has received the 2026 Nobel Prize in Physics for his work on astrophysical neutrinos, built around the IceCube Neutrino Observatory he helped develop beneath Antarctic ice. IceCube uses thousands of light sensors in a cubic kilometer of ice to detect neutrinos and has traced them back to cosmic sources such as supermassive black holes.
The Royal Swedish Academy of Sciences awarded the 2026 Nobel Prize in Chemistry to Henri B. Kagan of Université Paris-Sud and Kenso Soai of Tokyo University of Science. The prize recognises their discovery of non-linear effects and autocatalysis in asymmetric organic synthesis, work that explains how chemical reactions can favour one mirror-image molecule over another.
The Nobel Prize in Chemistry for 2026 has been awarded to Henri Kagan and Kenso Soai for their research into how asymmetric catalysis can amplify molecular handedness. Kagan's 1980s work showed catalysts could amplify a small imbalance between mirror-image molecules, while Soai's 1990s experiments demonstrated a molecule could catalyse its own further asymmetric production, a phenomenon now known as the Soai reaction.
The Royal Swedish Academy of Sciences awarded the Nobel Prize in Chemistry to Henri Kagan of the University of Paris-Sud and Kenso Soai of Tokyo University, splitting the 12-million-kronor prize. Kagan's 1980s experiments showed how small imbalances in molecular handedness could be amplified, while Soai's 1990s work demonstrated that a single-handed molecule could catalyze production of more molecules sharing its own chirality, together explaining how life's building blocks end up uniformly 'one-handed.'
The Nobel Prize in Physics has been awarded to Francis Halzen for his contributions to neutrino detection and astrophysics. The announcement highlights his role in advancing the understanding of cosmic neutrinos and their significance in astrophysical phenomena. The award underscores the importance of neutrino research in expanding knowledge of the universe.
Physicist Francis Halzen has been awarded the 2026 Nobel Prize in Physics for founding the IceCube Neutrino Observatory and for discovering high-energy neutrinos originating from deep space. IceCube, built below the Antarctic ice, detects rare interactions between neutrinos and atoms, capturing particles emitted by cosmic events like supernovae and gamma-ray bursts. Halzen noted the project succeeded within two years of operation, despite initial skepticism from the physics community.
Francis Halzen has been awarded the 2026 Nobel Prize in Physics for leading development of IceCube, the cubic-kilometre neutrino detector at the South Pole. The observatory achieved a landmark result in 2017 by tracing a high-energy neutrino back to a blazar, marking the first confirmed source identification of its kind and advancing 'multi-messenger' astronomy, which combines neutrinos, cosmic rays, light and gravitational waves to study cosmic events.
Physicist Francis Halzen received the 2026 Nobel Prize in Physics for establishing the IceCube Neutrino Observatory and discovering high-energy neutrinos originating from space. The award was announced on October 6 by the Royal Swedish Academy of Sciences, with Halzen emphasizing the collaborative effort behind the project. Neutrinos, abundant yet elusive particles, are key to understanding energetic cosmic events, and IceCube’s location at the South Pole enables unique astrophysical insights.
Karl Deisseroth, Peter Hegemann, and Georg Nagel received the Nobel Prize in Physiology or Medicine for their pioneering work in optogenetics, a technique that enables precise control of neural activity. Their research has opened new avenues for studying neurological and psychiatric conditions.
