Biomolecules from small amino acids to large DNA helices are chiral, and how they interact depends on their chirality. A newly identified quantum effect could help explain how biomolecules’ chirality persists.

When two molecules interact, their electron clouds reorganize. In chiral molecules, that reorganization is accompanied by electron spin polarization that enables molecules of the same chirality to interact more strongly than molecules of opposite chirality, reports a research team led by . . .
