Scientists from Los Alamos National Lab have discovered how to look through and map just about anything with a new process: the science-fictionally sounding muon tomography. Even in places like the highly radioactive Fukushima reactor, the method doesn't require any disassembly or any need for x-rays or ultrasound. Instead it logs the movement of muons (of course), a radioactive subatomic particle that exists, well, everywhere. Two giant aluminum sides are put either side of whatever needs looking into, and the system measures the trajectory of these muon particles. From this, the scientists are able sketch the object, given enough of the tiny things.
