Electrons in stacked sheets of staggered graphene collectively act as though they have fractional charges at ultra-low temperatures.Credit: Ramon Andrade 3DCiencia/Science Photo Library Minneapolis, Minnesota Last May, a team led by physicists at the University of Washington in Seattle observed something peculiar. When the scientists ran an electrical current across two atom-thin sheets of molybdenum … Read more
Scientists have long accepted the existence of animal culture, be that tool use in New Caledonian crows, or Japanese macaques washing sweet potatoes. Read the paper here: Bumblebees socially learn behaviour too complex to innovate alone But one thing thought to distinguish human culture is our ability to do things too complex to work out … Read more
