Israeli research offers a solution to the mystery of life's directionality

New research from the Weizmann Institute and the Hebrew University of Jerusalem offers a solution to a 150-year-old mystery: why the molecules of life chose one orientation. The researchers found that chiral molecules that appear as mirror images respond differently when

It started with very strange experimental results, continues in a new physical theory about the behavior of photons, and in the future may improve our smartphone screens and enable faster data communication.

The scientists took advantage of the fact that chirality affects an electron property called "spin," which has two states – "spin up" and "spin down" – similar to the clockwise or counterclockwise spinning of a spinning top. Illustration: Prof. Ron Naaman, Weizmann Institute
