    Developing micron-sized magnetic resonance

    Harvard scientists have developed a system that uses nitrogen-vacancy centers — atomic-scale impurities in diamonds — to read the nuclear magnetic resonance signals produced by samples as small as a single cell — and they did it on a shoestring budget using a 53-year-old, donated electromagnet.

    Diamonds are a lab’s best friend

    Using the atomic-scale quantum defects in diamonds known as nitrogen-vacancy centers to detect the magnetic field generated by neural signals, scientists working in the lab of Ronald Walsworth, a faculty member in Harvard’s Center for Brain Science and Physics Department, demonstrated a noninvasive technique that can show the activity of neurons.

    Harvard researchers stop, restart, light

    Albert Einstein theorized that light cannot travel faster than 186,282 miles per second. But he never said it couldn’t go slower. Lene Hau, a physics professor in the Faculty of…
