How is it possible for a human eye to figure out letters that are twisted and looped in crazy directions, like those in the little security test internet users are often given on websites? It seems ...

Taking advantage of molecules that switch states when exposed to particular wavelengths of light, researchers have developed a 3-D printing method that can make precise objects in a matter of minutes.

[Matthias], eminent woodworker he is, designed and built an awesome machine to make copies of just about any object imaginable. With a few scrap 2x4s, and a few bolts, screws, and skateboard bearings, ...
