Researchers have developed a new way to see organs within a body by rendering overlying tissues transparent to visible light.

Illustrated here: a human hand as it might appear if the new tissue transparency effect proves effective in humans. Currently, the effect has only been tested with animals in a laboratory setting. Note that dyes may be harmful. Always exercise caution with dyes and do not consume directly, apply to people or animals, or otherwise misuse.
