Why this year's Nobel Prizes left out many key scientists behind major breakthroughs

The 2026 Nobel Prizes highlight a growing gap between individual award winners and the large teams of researchers truly responsible for major scientific breakthroughs. Rules set by the Nobel Foundation limit each prize to at most three living people, which often excludes vital contributors to winning discoveries.

Medicine Prize

The 2026 physiology or medicine prize went to Karl Deisseroth, Peter Hegemann, and Georg Nagel for optogenetics work. However, Gero Miesenböck first made neurons light-sensitive in 2002 at the University of Oxford. Edward Boyden and Feng Zhang at MIT also played crucial roles in applying and adapting channelrhodopsin and halorhodopsin proteins to control or silence neurons with light.

Physics Prize

The physics prize was awarded solely to Francis Halzen for the IceCube Neutrino Observatory and high-energy neutrino discoveries. IceCube is an international collaboration involving around 450 experts from 58 institutions across 14 countries. In 1988, Halzen and John G. Learned proposed using Antarctic ice to catch space neutrinos. Later, scientists including Aya Ishihara found key data events in 2012, while Claudio Kopper, Naoko Kurahashi, and Nathan Whitehorn were corresponding authors on the 2013 paper reporting them.

Chemistry Prize

The chemistry prize spotlighted work on chemical asymmetry but bypassed key researchers due to rules barring posthumous awards and choices to exclude living scientists. Frederick Charles Frank devised a mathematical model in 1953 for chemical imbalance, which Henri Kagan and Kenso Soai later tested. Takanori Shibata extended this work in a 1999 paper, while U.S. chemical engineer Donna Blackmond further explained the Soai reaction mechanism.

Context

Scientific progress relies on collaborative networks, graduate students, technicians, and decades of cumulative research rather than single discoverers. While Nobel Prizes celebrate major milestones, they capture only a fraction of the workforce required to drive modern science forward.
