The 2026 Nobel Prize announcements have highlighted contributions to science, literature, international law and economics, with laureates recognised across six categories for work aimed at advancing knowledge and benefiting humanity.

The annual announcements began on October 5 with the Nobel Prize in Physiology or Medicine and concluded on Monday, October 12, with the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel.

The six categories cover physiology or medicine, physics, chemistry, literature, peace and economic sciences. The prizes recognise achievements ranging from scientific discoveries and literary creativity to efforts to strengthen international justice and improve understanding of economic policy.

The Nobel Prize was established through the will of Swedish inventor and industrialist Alfred Nobel, who directed that his fortune be used to reward individuals whose contributions brought significant benefits to humanity.

The economics prize was introduced later by Sweden’s central bank, Sveriges Riksbank, in memory of Alfred Nobel. It was first awarded in 1969.

1. Medicine: Karl Deisseroth, Peter Hegemann and Georg Nagel
The Nobel Prize in Physiology or Medicine was reported to have been awarded to American scientist Karl Deisseroth and German scientists Peter Hegemann and Georg Nagel for discoveries involving light-gated ion channels and optogenetics.

Optogenetics is a research technique that enables scientists to control the activity of specific nerve cells using light. The method has become an important tool in neuroscience, allowing researchers to investigate how particular brain cells influence memory, emotions, movement and behaviour.

Hegemann and Nagel contributed to the discovery and study of light-sensitive proteins found in algae, while Deisseroth helped develop techniques for applying these discoveries to the study of nerve cells.

The approach has expanded researchers’ ability to investigate brain activity and explore the biological mechanisms underlying neurological and psychiatric conditions.

About the reported winners
Karl Deisseroth: Born in 1971, Deisseroth is an American neuroscientist and psychiatrist at Stanford University, where he is a professor of bioengineering and psychiatry and behavioural sciences. He obtained his medical and doctoral degrees from Stanford.

Peter Hegemann: Born in 1954, Hegemann is a German neuroscientist associated with Humboldt University of Berlin.

His research has focused on light-sensitive proteins and the mechanisms through which organisms respond to light.

Georg Nagel: Born in 1953, Nagel is a German scientist and professor of molecular plant physiology at the University of Würzburg. His work on light-sensitive proteins contributed to the development of optogenetics.

2. Physics: Francis Halzen
Belgian-American physicist Francis Halzen was reported to have won the 2026 Nobel Prize in Physics for his contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos originating from astrophysical sources.

Neutrinos are subatomic particles that interact extremely weakly with matter, allowing them to travel vast distances through the universe with little interference.

Studying these particles gives scientists another way to investigate some of the universe’s most energetic phenomena, including processes associated with distant galaxies and black holes.

Halzen played a leading role in developing the IceCube Neutrino Observatory, a large scientific installation embedded in Antarctic ice near the South Pole.

The observatory uses thousands of optical sensors to detect faint flashes of light produced when neutrinos interact with matter. These observations help scientists trace the particles to their possible cosmic sources.

About the reported winner
Halzen was born in Belgium in 1944. He studied at the Catholic University of Leuven, now KU Leuven, where he obtained his master’s and doctoral degrees.

He joined the University of Wisconsin–Madison’s physics faculty in 1972 and became a leading figure in neutrino astronomy.

His work on IceCube helped establish neutrino detection as an important method for studying the universe beyond conventional astronomical observations.

3. Chemistry: Henri B. Kagan and Kenso Soai
French chemist Henri B. Kagan and Japanese chemist Kenso Soai were reported to have won the 2026 Nobel Prize in Chemistry for research involving asymmetric organic synthesis and chemical reactions that favour one of two mirror-image forms of a molecule.

Many molecules exist in two forms that resemble each other as mirror images but cannot be superimposed. These forms, known as enantiomers, can behave differently in biological systems.

Controlling which form a chemical reaction produces is particularly important in pharmaceutical research because different molecular forms can interact differently with biological targets.

Kagan’s research advanced asymmetric catalysis, which enables chemists to favour the production of one molecular form over another.

Soai became known for research into asymmetric autocatalysis, in which a reaction product helps promote the production of more molecules with the same handedness. This work is associated with the Soai reaction.

Together, their reported contributions highlight the importance of controlling molecular structure in modern chemistry.

About the reported winners
Henri B. Kagan: Kagan is a French chemist recognised for his research in stereochemistry and asymmetric catalysis. He has been associated with Université Paris-Sud, now part of Université Paris-Saclay.

His work contributed to methods for controlling the three-dimensional structures of molecules produced during chemical reactions.

Kenso Soai: Born in Hiroshima Prefecture, Japan, in 1950, Soai graduated from the University of Tokyo and obtained a Doctor of Science degree.

He later became a professor at Tokyo University of Science, where his research on asymmetric autocatalysis led to the discovery associated with the Soai reaction. He is now a professor emeritus at the institution.

4. Literature: Anne Carson
Canadian poet, essayist, classicist and translator Anne Carson was reported to have received the 2026 Nobel Prize in Literature for a body of work combining classical traditions with innovative forms of contemporary writing.

Carson’s writing frequently explores ancient Greek literature, philosophy and mythology while connecting classical ideas with modern experiences.

Her work crosses conventional boundaries between poetry, prose, translation and literary scholarship, creating a distinctive style that has attracted international recognition.

Her reported selection highlights the continuing influence of classical literature on contemporary writing and the possibilities of combining academic scholarship with creative expression.

About the reported winner
Carson was born on June 21, 1950, in Toronto, Canada.

She studied at the University of Toronto, earning bachelor’s and master’s degrees in 1974 and 1975, respectively, before completing her PhD there in 1981.

Her notable works include Eros the Bittersweet, Autobiography of Red and If Not, Winter: Fragments of Sappho.

Carson has received several literary honours, including a MacArthur Fellowship, Guggenheim Fellowships and Spain’s Princess of Asturias Award for Literature. She was appointed a Member of the Order of Canada in 2005.

5. Peace: Navanethem ‘Navi’ Pillay
South African jurist and former United Nations High Commissioner for Human Rights Navanethem ‘Navi’ Pillay was reported to have won the 2026 Nobel Peace Prize for her contributions to international law, human rights and efforts to promote accountability for serious international crimes.

Her reported recognition underscores the role of legal institutions in addressing war crimes, crimes against humanity and genocide.

Pillay’s career has included defending activists during apartheid, serving in international judicial institutions and leading human rights work at the United Nations.

Her work has focused on strengthening the international legal framework for protecting human rights and ensuring that perpetrators of serious violations can be held accountable.

Between 2021 and 2025, she chaired the UN Independent International Commission of Inquiry on the Occupied Palestinian Territory.

6. Economic Sciences: Robert E. Hall and Michael Woodford
American economists Robert E. Hall and Michael Woodford were reported to have received the 2026 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel for work described as concerning the microeconomic foundations of macroeconomic stabilisation.

The Royal Swedish Academy of Sciences reportedly announced the award on Monday, October 12, concluding this year’s Nobel Prize announcement calendar.

The research attributed to the economists focuses on improving the understanding of how governments and central banks can stabilise economies during recessions and periods of rapid economic growth.

The underlying approach considers how individual households and businesses make decisions about spending, saving, investment and prices, as well as how their expectations about future government policies influence economic activity.

By incorporating these decisions into broader economic models, researchers can better examine the effects of fiscal and monetary policies.

Such research is relevant to debates about inflation, unemployment, interest rates and the measures governments and central banks use to respond to economic instability.

About the reported winners
Robert E. Hall: Born in 1943 in Palo Alto, California, Hall obtained his PhD from the Massachusetts Institute of Technology in 1967.

He is a professor at Stanford University and is known for research into macroeconomics, economic fluctuations and consumer behaviour.

Michael Woodford: Born in 1955 in Chicopee, Massachusetts, Woodford obtained his PhD from the Massachusetts Institute of Technology in 1983.

He is a professor at Columbia University in New York and is recognised for his work on monetary policy, economic expectations and macroeconomic theory.

How the economics prize differs from the original Nobel Prizes
The economics award differs from the five original Nobel Prize categories because it was established by Sweden’s central bank in 1968 in memory of Alfred Nobel and first awarded in 1969.

Although it is not one of the original categories specified in Nobel’s will, it is administered alongside the other Nobel Prizes and follows a similar selection and presentation process.

When will the 2026 Nobel Prizes be presented?
The Nobel laureates traditionally receive their medals and diplomas at ceremonies held on December 10, the anniversary of Alfred Nobel’s death in 1896.

The Nobel Peace Prize ceremony takes place in Oslo, Norway, while the ceremonies for the other Nobel Prize categories are held in Stockholm, Sweden.

The annual awards recognise achievements across scientific research, literature, peace and economic sciences, drawing international attention to work that has influenced knowledge, public policy and society.
