Today I learned about a group at Stanford that have figured out a way to make biological tissues invisble! They don't call it invisible...they use the term "clarity" but basically you can see through the tissue!
You've got to see this! Below is a mouse brain before and then after 2 days of the clarity process in which a gel is placed around the brain to hold its structure and then fats are removed which leave the brain see through! Isn't it cool?!!
Check out this cool youtube video about the process!
