There's a new way to watch proteins shimmy and dance as they carry out their biological tasks. Researchers traditionally deduce these motions from changes in the molecules' ability to absorb particular wavelengths of light. Now a group of researchers has taken a more direct approach, using a modified atomic force microscope. They planted the tip of an ultrafine glass fiber on top of the protein and actually felt it move.
