Tartrazine WTF🐭
The breakthrough could revolutionize biomedical research and, should it be successfully tested in humans, have wide-ranging applications in medicine and health care, such as making veins more visible to draw blood.
Researchers made the skin on the skulls and bellies of live mice transparent by applying a mixture of water and a yellow food coloring called tartrazine. Washing away any remaining solution reversed the process, which did not harm the animals. The mice’s fur was removed before the application of the solution.
