Protein Vibrations (image) University at Buffalo Caption Using a new imaging technique they developed, scientists have managed to observe and document the vibrations of lysozyme, an antibacterial protein found in many animals. This graphic visualizes the vibrations in lysozyme as it is excited by terahertz light (depicted by the red wave arrow). Such vibrations, long thought to exist, have never before been described in such detail, said lead researcher Andrea Markelz, a UB physicist. Credit Credit: Andrea Markelz and Katherine Niessen.
