Optogenetics Pioneers Win Medicine Prize

The 2026 Nobel Prize in Physiology or Medicine has been awarded to Karl Deisseroth, Peter Hegemann, and Georg Nagel for their groundbreaking discoveries concerning light-controlled ion channels and optogenetics.

Hegemann and Nagel first identified the protein channelrhodopsin in single-celled algae. Building on this foundation, Deisseroth transformed this protein into a light-controlled switch for neurons, effectively laying the groundwork for a new era in neurobiology.

Last year’s medicine prize recognized Mary Brunkow, Fred Ramsdell, and Shimon Sakaguchi for their work on peripheral immune tolerance. Historically, 116 Nobel Prizes in Medicine have been awarded between 1901 and 2025. The youngest laureate was Frederick Banting, who co-discovered insulin at age 31 in 1923, while the oldest was Peyton Rous, honored at 87 in 1966 for his discovery of tumor-inducing viruses.

Physics Prize Goes to IceCube Director

Francis Halzen has been awarded the 2026 Nobel Prize in Physics for his decisive contribution to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin.

Often referred to by physicists as the «ghosts of the universe,» neutrinos are elusive elementary particles. Halzen’s visionary idea was to use the deep glaciers of the South Pole to trap these cosmic messengers. As the co-founder and director of the IceCube Observatory at the Amundsen-Scott South Pole Station, Halzen helped achieve a major milestone in 2013 with the detection of high-energy astrophysical neutrinos. The observatory has since mapped neutrino emissions from active galaxies and objects within the Milky Way.

In 2025, the physics prize was awarded to John Clark, Michelle Devore, and John Martinis for their advancements in quantum mechanics. Since 1901, the physics prize has been awarded 119 times. William Lawrence Bragg remains the youngest laureate at 25 (1915), while Arthur Ashkin was the oldest at 96 (2018). John Bardeen is the only individual to have won the Physics Nobel twice.

Chemistry Laureates Advance Drug Design

French chemist Henri B. Kagan and Japanese chemist Kenso Soai share the 2026 Nobel Prize in Chemistry for their discovery of nonlinear effects and autocatalysis in asymmetric organic synthesis.

Many molecules, such as amino acids, exist in two mirror-image forms, yet living organisms predominantly utilize only one—a property known as homochirality. In 1986, Kagan established the theoretical framework to control chemical reactions to produce a greater excess of one mirror-image form. Soai translated this theory into practice, publishing a potentially homochiral reaction in 1995 and successfully demonstrating a reaction yielding only one mirror-image form in 2003. Their work has profound practical implications, particularly in the pharmaceutical industry for drug development.

Between 1901 and 2025, the Chemistry Nobel has been awarded 117 times. Frederick Sanger and K. Barry Sharpless are the only two-time winners. Frédéric Joliot-Curie was the youngest laureate at 35, and John Goodenough the oldest at 97.

Anne Carson Awarded Literature Prize

The 2026 Nobel Prize in Literature has been awarded to Canadian writer Anne Carson for her «bold and innovative writing that, in playful dialogue with the classical tradition, has created new forms for contemporary literature.»

A classically trained philologist, Carson has seamlessly blended poetry, translation, and academia throughout her career. Her translations of ancient Greek texts—including works by Sappho, Sophocles, and Euripides—are considered standalone literary achievements. Her seminal 1990s works, The Glass Essay and Autobiography of Red: A Novel in Verse, brilliantly merge ancient narratives with modern sensibilities. Her 2024 collection pushed the boundaries of literature even further by integrating theatrical elements and collaborating with visual artists and choreographers.

Last year’s literature laureate was Hungarian writer László Krasznahorkai. Since 1901, 118 Literature Prizes have been awarded to 18 women. Rudyard Kipling was the youngest recipient at 41 (1907), and Doris Lessing the oldest at 88 (2007).

The 2026 peace laureate

The Norwegian Nobel Committee has decided to award the Nobel Peace Prize for 2026 to Navi Pillay «for her efforts to promote peace and international law.»

Navi Pillay’s commitment to universal legal principles and her firm moral compass are constants in a long career. A common thread runs from her early work defending Nelson Mandela and others who stood up against apartheid to her service as a judge in some of the key international court cases of our time.

Navi Pillay has held states and national leaders accountable and brought hope to victims of violence and conflict. In all the positions she has held, she has stressed the responsibility of individuals and states to comply with the rule of law.

Nobel Prize in Economics Laureates

The 2026 Nobel Memorial Prize in Economic Sciences has been awarded to Michael Woodford (Columbia University, USA) and Robert E. Hall (Stanford University, USA) for their work on the «microeconomic foundations of macroeconomic stabilization,» according to the official Nobel Prize website.

«This year’s Laureates in Economic Sciences, Robert E. Hall and Michael Woodford, have developed new macroeconomic models that have significantly improved our ability to conduct effective stabilization policies. Guided by these models, timely fiscal and monetary policy measures can mitigate economic downturns and booms,» the announcement states.

The committee noted that the scientists were honored «for demonstrating how economic models can be restructured to enhance stabilization policies.» Rather than basing their models on statistical correlations between macroeconomic variables such as inflation, output, and consumption, they chose to build them on microeconomic foundations. This involves understanding how the aggregate actions of individual households and firms impact the broader economy.

A key element of these models is that households and firms are forward-looking when making decisions about savings or pricing their goods. When governments and central banks communicate their economic policy plans, they can influence these future expectations and steer the economy in the desired direction. Since their introduction, these new models have proven invaluable in combating economic downturns.

The laureates’ work has provided a «solid theoretical foundation for the models now used by central banks and governments worldwide.»

«Thanks to them, we are better equipped to weather economic shocks, such as energy crises or sudden shifts in household consumption,» stated John Hassler, Chair of the Committee for the Prize in Economic Sciences.

The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel was established by Sweden’s central bank in 1968 and has been awarded since 1969, following the same principles as the original five Nobel Prizes. Between 1969 and 2025, the prize was awarded 57 times to 99 laureates.

Esther Duflo remains the youngest laureate in the history of the Economics Prize, having received the award in 2019 at the age of 46. The Massachusetts Institute of Technology professor was honored for her experimental approach to alleviating global poverty.

The oldest laureate of the Economics Prize is American economist Leonid Hurwicz, who was 90 years old when he received the award in 2007. He was awarded the prize for his foundational contributions to mechanism design theory, which helps distinguish between situations where markets function efficiently and those where they fail.
