If you want to show the world what you're REALLY made of, guts and all, then your wait is almost over. Thanks to Japanese researchers from RIKEN, biological tissue can be turned transparent via chemical reagent, so you can look like a superhero without the need to have powers or a cool alien back story. Unfortunately, this reagent doesn't work on living tissue, so you'll have to wait a while longer for your clear skin makeover. Until then, read on at PopSci and imagine all the creepy possibilities!
