Seeing Indigenous people in science can be transformative. It connects the past, present, & future, inspiring generations to come. For her, supporting students helps them become scientists and problem solvers who create innovative science solutions. Here's how she does it. [2/3]

Sarah EchoHawk believes everyone should feel a sense of belonging in science. Through AISES, Indigenous students can find community by seeing themselves represented in the field. [1/3]

This was the final experimental proof of a theoretical model from 1953 outlining the requirements for the chemical “evolution” of homochirality: an asymmetric reaction that’s self-catalyzing and shows mutual inhibition between the two possible chiral products. [6/7]

@acs.orgOct 7, 2026, 7:32 PM

Kensō Soai reported a reaction in 1990 that was both autocatalytic & enantioselective — two things that had been done before but never together. 5 years later, Soai & colleagues reported an asymmetric autocatalytic reaction in which the product had a higher enantiomeric excess than the catalyst. 5/7

@acs.orgOct 7, 2026, 7:32 PM

Henri B. Kagan showed in 1986 that a small excess of one catalytic enantiomer can lead to a larger excess of the desired product due to mutual inhibition, a phenomenon known as “non-linear effects.” 4/7

We knew of reactions that could make chiral molecules from achiral ones, but the products would be 50/50 mixtures. A reaction that could create an enantiomerically pure product from completely achiral reagents seemed elusive, until … 3/7

@acs.orgOct 7, 2026, 7:32 PM

The amino acids, sugars, and nucleic acids that make up our cells are homochiral, which means that in living systems you’ll only find one enantiomer, or one molecular version of a mirror-image pair. 2/7

@acs.orgOct 7, 2026, 7:32 PM

These two researchers helped answer one of the great questions of science: How could nature create homochirality from achiral starting materials?

Congratulations to Henri B. Kagan and Kensō Soai, the laureates of the 2026 Nobel Prize in Chemistry! They are sharing the award equally for their work on designing reactions that selectively form only one enantiomer of a chiral molecule.
