Devices that use the spin property of electrons to store and process information are one step closer to reality, thanks to a new MRI technique with a resolution tens of thousands of times better than an MRI brain scan. Researchers at Harvard University and the Harvard-Smithsonian Center for Astrophysics can now watch many electrons spin at the same time — and change the spin of a single electron without disturbing its neighbor. The device was tested on a piece of diamond but could be used to monitor many different kinds of materials, as reported in Nature Physics on May 15. —Devin Powell
