Microcline can trigger ice formation across ordinary flat mineral terraces, rather than relying mainly on cracks, pores or other rare surface defects. Its unusually strong ice-nucleating ability appears tied to an ordered pattern of aluminol groups that helps stabilize hydrogen bonds with water. Closely related sanidine behaves differently, showing how...
Two newly published studies suggest that psychedelic compounds may offer a novel approach to treating cocaine addiction. A clinical trial published in JAMA Network Open found that psilocybin combined with psychotherapy helped people stop using cocaine.
