Ordinarily, when scientists want to see specific cells within a piece of biological tissue, they first have to remove that tissue from the body, slice it very thin, then examine those two-dimensional slices using a microscope. Imagine, though, if the tissue could be made transparent – seeing tagged cells within it would be sort of like looking at three-dimensional bubbles inside an ice cube. Well, that's just what a team at Caltech have done using a technique known as PARS, or perfusion-assisted agent release in situ... Continue Reading PARS tech turns bodies transparent
