Two independent teams of physicists, one in the US and the other in Germany, have measured magnetic fields on the nanoscale at room temperature for the first time. Both techniques rely on exploiting "nitrogen-vacancy" defects in diamond and can sense the magnetic signals from individual electrons and atomic nuclei placed nearby. Being able to detect such tiny magnetic fields under ambient conditions opens the way to applications in biology but also in materials science, spintronics and quantum information.
