Molecular Mirror Images Earn Chemistry’s Highest Honor

Ill. Niklas Elmehed © Nobel Prize Outreach

The 2026 Nobel Prize in Chemistry honors Henri B. Kagan and Kenso Soai for discoveries involving molecular “handedness.” Their work highlights why three-dimensional structure matters—from understanding life’s building blocks to developing medicines—and connects closely with crystallography’s ability to reveal how atoms are arranged.

A Crystal-Clear Congratulations!

The ACA congratulates Francis Halzen on receiving the 2026 Nobel Prize in Physics for his contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos from cosmic sources. By using Antarctic ice to detect these elusive particles, IceCube gives scientists a new way to explore the universe’s most powerful events. For the ACA community, this achievement highlights how innovative instruments and collaboration help reveal what we cannot see directly—a principle central to crystallography. For all of us, it offers new opportunities to understand the universe and inspires curiosity about the world around us.
