Chirality is a key aspect in the expression, preservation, and inheritance of biologically genetic information and is vital to life. 1, 2 Depending on their chirality, amino acids, carbohydrates, proteins, RNA, and DNA play critical roles as carriers, expressers, and users of molecular chirality in biological processes, such as catalysis, … Web1 day ago · Wang and Sugiyama swapped mechanical poking for a perturbation with a chiral bias to it. They exposed single metastable sodium chlorate crystals to intense pulses of circularly polarized laser light (each pulse at 800 nm with a duration of 120 fs). 5 The pulses were tightly focused to a micron-scale patch on the surface of small crystals. The …
