    This is an atomic force microscopy image of a graphene sheet draped over a Bacillus bacterium (left). The bacterium is about 1 micron or 1/25,000 of an inch wide. After applying vacuum and heat treatment, regular wrinkles form in the graphene (right, at twice the magnification). Credit: UNIVERSITY OF ILLINOIS AT CHICAGO/Vikas Berry

    New nanomaterial conducts differently at right angles. Now University of Illinois at Chicago researchers have used rod-shaped bacteria – precisely aligned in an electric field, then vacuum-shrunk under a graphene sheet – to introduce nanoscale ripples in the material, causing it to conduct electrons differently in perpendicular directions...
