Smartphones may soon be able to see through walls

Brace yourselves: The future just walked in the door, because soon smartphones are going to allow you to LOOK THROUGH WALLS, as well as wood, plastics, paper ... and clothes. University of Texas, Dallas, researchers are translating an "unused range in the electromagnetic spectrum" called the terahertz band (sounds like fancy talk for magic) through microchips made of CMOS (Complementary Metal-Oxide Semiconductor, aka wizardry) into images which can be seen via a computer or smartphone. This technology has basically limitless implications, from detecting counterfeit money to helping doctors identify tumors. However, if you're nervous this could turn the world into an unwilling peepshow, relax: Researchers want to focus on uses in a range of less than four inches.
