What this year's Nobel prizes teach about long bets and open sharing

At a glance: Between 5 and 7 October 2026, the Nobel Prizes in medicine, physics and chemistry went to work that took decades to pay off. Karl Deisseroth, Peter Hegemann and Georg Nagel were honoured for discoveries leading to optogenetics; Francis Halzen for the IceCube Neutrino Observatory; Henri Kagan and Kenso Soai for advances in asymmetric synthesis. For companies, the prizes are a case study in patient research and the value of sharing tools openly.

Medicine: a tool that spread because it was shared

On 5 October, the Nobel Prize in Physiology or Medicine went to Karl Deisseroth of Stanford University, Peter Hegemann of Humboldt University of Berlin and Georg Nagel of the University of Würzburg, for discoveries leading to optogenetics.

Optogenetics uses light to switch individual nerve cells in a living brain on or off. Deisseroth's approach inserts light-sensitive proteins from microbes, called opsins, into mammalian brain cells. Shine the right light, and the cell fires or falls silent. Deisseroth explains it to children more simply: "We're poking the brain."

The timeline is instructive. Deisseroth's lab opened in July 2004, when he and two graduate students began the project. A 2005 paper described an engineered opsin that fires neurons under blue light. More than two decades later, the work has won a Nobel.

What made optogenetics spread was not only the science. According to Stanford Medicine, Deisseroth freely shared reagents, protocols and knowledge with as many scientists as possible. His lab distributed copies of the engineered opsin gene to laboratories around the world, and his Stanford programme has trained thousands of scientists in the technique. A tool that could have stayed in one lab became a standard method across neuroscience.

Physics: a forty-year bet under the South Pole

On 6 October, the Nobel Prize in Physics went to Francis Halzen, 82, of the University of Wisconsin–Madison, for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin.

Neutrinos are tiny particles produced by some of the most energetic events in the universe. They are extremely hard to catch. Halzen, who joined the Wisconsin physics faculty in 1972, began working on the idea of detecting them in Antarctic ice in the 1980s, and proposed and demonstrated that ice could serve as the detector. He oversaw the design and development of IceCube and its predecessor, AMANDA.

The result is a detector covering about one cubic kilometre of glacial ice at the South Pole. It is funded and operated mainly by the US National Science Foundation through the University of Wisconsin–Madison, and the collaboration now involves about 450 scientists from 58 institutions in 14 countries. The first astrophysical neutrinos were reported in 2013. In 2023 IceCube reported neutrinos from our own galaxy, the Milky Way.

Mark Pearce, chair of the Nobel Committee for Physics, said Halzen "has led an international team of researchers and engineers who have provided us with a fantastic instrument". Halzen called the prize "a celebration of a very unusual project" and said: "It's a great relief for me to finally deliver the recognition that this great collaboration deserves."

Chemistry: solving an old puzzle about mirror images

On 7 October, the Nobel Prize in Chemistry went to French chemist Henri Kagan and Kenso Soai, professor emeritus at Tokyo University of Science, for their discoveries of non-linear effects and autocatalysis in asymmetric organic synthesis.

Many molecules come in two mirror-image forms, like left and right hands. In medicines, flavours and materials, one form can behave very differently from the other. Kagan showed that reactions could be steered to produce one form in far greater excess than previously thought possible. Soai designed a reaction, now known as the Soai reaction, that produces only one of the possible mirror-image forms. Heiner Linke, chair of the Nobel Committee for Chemistry, said the two had "provided a solution to a chemical mystery that is over a century old".

Soai, born in 1950, made the discovery during his career at Tokyo University of Science. His first words of thanks went to his team: "I was able to reach this point thanks to the students."

Analysis: three lessons for corporate R&D

The following is WCRC Leaders' interpretation, not a finding from the Nobel committees.

Long horizons still pay. Optogenetics took about two decades from first experiment to Nobel. IceCube took roughly three decades from idea to first discovery. Most corporate R&D portfolios are judged on far shorter cycles. The prizes do not argue that every bet should run for 30 years, but they suggest that a portfolio with no long bets at all may miss the discoveries that later define a field.

Sharing can multiply value. Deisseroth's open distribution of tools turned a lab method into an industry standard. In business terms, giving away the platform built the market. Companies that share research tools, data formats or standards, while protecting what truly differentiates them, can grow the ecosystem their own products depend on.

Big science is team science. IceCube is a collaboration of hundreds of scientists across many countries, and both Halzen and Soai credited their teams first. Corporate R&D increasingly relies on partnerships with universities, suppliers and even competitors. Governance, credit-sharing and long-term funding commitments are part of the research strategy, not an administrative afterthought.

What it means for leaders

• Ring-fence a share of R&D for long-horizon projects with milestones measured in learning, not quarterly revenue.
• Decide deliberately what to share: research tools and standards can grow your market, while core know-how stays protected.
• Build university and consortium partnerships with funding horizons that match the science.
• Recognise and credit research teams publicly; talent follows organisations that do.
• Review how your R&D governance would treat a project like IceCube: would it have survived its first ten years?
