Physicists Find Light-sensitive Molecule Can Heal Itself in the Dark Sometimes all an overworked molecule needs is a good night`s rest. According to a study by physicist Mark Kuzyk and colleagues at Washington State University, a molecule that loses its ability to fluoresce when struck by a laser beam regains that ability if it`s allowed to ‘rest` in the dark. Recovery begins within 30 minutes and is nearly complete after 8 hours of rest, the study found.
