Nobel Prize in Chemistry 2026 awarded for solving how life's mirror-image molecules emerged
Nobel Prize in Chemistry 2026 to Henri B. Kagan and Kenso Soai
Henri B. Kagan and Kenso Soai share the 2026 Nobel Prize in Chemistry for discovering non-linear effects and autocatalysis in asymmetric organic synthesis. Kagan's 1986 work showed how to create a greater excess of one mirror-image molecule, and Soai's 1995-2003 experiments produced the first reaction that spontaneously formed only one mirror image. Their findings explain how homochirality—the single-handedness of life's molecules—could arise and aid drug design.
Other than life itself, no one had previously achieved this feat.

I remember first learning about chirality in my biochemistry course in college, and it was definitely a mind-blower. I had already started to understand that molecules had 3d structures, but the idea (and attempting to visualize it mentally) of mirror image molecules stretched my brain significantly.
It's also still amazing to me how people first recognized this: poking around looking at the crystals that form in the bottom of a wine under a microscope, noticing that some of them were mirror images of the other, and then seperating them manually with tweezer, dissolving them into two different solutions, and demonstrating that they rotated light in opposite directions.

Yeah, when you put it that way it sounds pretty impresive.

I have to admit that when I read the intro header of the piece on the page, “They made chemistry choose a mirror image,” it struck me as LLM-speak and I immediately lost interest. I have no idea whether the authors used one to draft that phrase, which seems like an innocent summary of their contributions, but somehow I feel like if it were three years ago we would have never seen that in the title.

Cool, brings back some memories from grad school. Always found these types of reactions with self-reenforcing quite interesting.
Reminds me of another paper where just stirring a solution or not would determine the chirality of crystals formed and gives an idea how highly chiral environments can arise from "nothing":
