Today, researchers at the California Institute of Technology revealed that they've created see-through mice. These creepy little guys will be used to help scientists track how disease makes its way through the body.
The see-through technique involves pumping a series of chemicals through blood vessels, as well as other passages in the brain and spinal cord. Some chemicals form a mesh to hold tissue in place. Others wash out the fats that make tissue block light. It takes about a week to create a transparent mouse.
Before all that, scientists euthanize and skin the mice. According to the AP, researchers can make rats transparent as well.
