New microscopy tracks molecules in live tissue at video rate; scientists push SRS microscopy to new levels of spatial, temporal precision

A novel type of biomedical imaging, made possible by new advances in microscopy, is so fast and sensitive it can capture "video" of blood cells squeezing through capillaries. The new technique makes possible label-free chemical movies, with streaming footage at the subcellular level, catching video of proteins, lipids, and water within cells........
