Isotope Chemistry Quantum Biology Origins of Life

Researchers from the Hebrew University of Jerusalem and the Weizmann Institute of Science have discovered that magnetic fields and electron spin can influence the behavior and separation of different isotopes of the amino acid L-methionine. The study suggests these quantum effects may have played a role in the chemical processes that led to the origins of life and the molecular chirality found in nature.
