Live Mouse Turned Temporarily Transparent Thanks To Yellow Food Dye And Clever PhysicsTime-lapse images of blood vessels in the brain just beneath the skull of a sedated mouse, revealed without any surgery, incisions, or damaging the mouse’s bone or skin. By reversibly dyeing the tissues with FD & C Yellow 5 and using a technique called laser speckle contrast imaging, Stanford University researchers observed the blood flow within this living brain.
