Chemical Cocktail Produces Transparent Mouse
“What goes on inside a mouse’s brain?
Even though researchers have developed ways to make neurons fluoresce, they have a hard time observing them in an intact animal.
Enter a new chemical cocktail named Scale. Researchers serendipitously discovered that a mixture of urea, glycerol, and soap makes synthetic membranes transparent.
When they tried the mixture on a developing mouse fetus, they found that it removed all of the pigment from the cells, rendering them completely transparent.”
