SUPER SHEET  Simple blender blades can slough off graphene, single-atom-thick layers of carbon, from  graphite. Graphene’s carbon atoms, depicted as bright blobs in this scanning transmission electron microscope image, form a chicken wire pattern.

ALL SPUN UP  Molecules hit with a laser have reached record spin speeds of 600 trillion revolutions per minute.

When plants make food, they absorb energy from light. Excitons move that energy to places in plants where it can be stored in its chemical form. Observing excitons in motion may help scientists better understand the process of photosynthesis.
