Holograms are pretty cool, sure. But they’re still just two-dimensional projections that hover in the air, and as soon as you step to the side, the magic disappears, revealing how flat the thing really is.   But now researchers from Brigham Young University have demonstrated they can create fully three-dimensional projections of moving images – and

The German physicist Albert Einstein needed complex equations to describe his theory of relativity, but 18-year-old Hillary Diane Andales of the Philippines does just fine with a pick-up truck, a few cell phones, and Usain Bolt.   Andales is the winner of the 2017 Breakthrough Junior Challenge, an annual competition that calls on teenagers across the

Achieving nuclear fusion without needing radioactive fuel or producing radioactive waste is now “within reach” thanks to a new laser-driven technique, according to researchers.   The type of fusion we’re talking about is hydrogen-boron fusion, which produces no neutrons and therefore no radioactivity in its primary reaction. The downside, and part of what’s made it

Researchers at MIT have invented a temporary “tattoo” made from genetically programmed living cells. Their prototype looks like a stick-on patch with a pattern in the shape of a tree.   It’s divided into sections printed with a slurry containing live bacteria that fluoresce when they come into contact with particular compounds. When the skin under
