Finding materials harder than diamond, plus spintronic devices, wrinkle physics and more in this week's news
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
