A story in the New York Times reports on a new technique to image viruses. Developed by IBM scientists and published in PNAS, magnetic resonance force microscopy, or M.R.F.M., is similar to MRI but offers 100 million times better resolution. The technique uses an "ultrasmall cantilever arm as a platform for specimens that are then moved in and out of proximity to a tiny magnet" and could be used by structural biologists to study the structure and interaction of proteins. "You have thousands of proteins in your body that have no known structure, because there's no technique to determine their structure," says Dan Rugar, manager of nanoscale studies at IBM Almaden Research Center and leader of the team that developed the new device, in a story in Technology Review.
