Laser Holograms as Thin as a Hair Could Be the Future of High-Res

Holograms are cool enough on their own, but amazing things happen when you make them incredibly small. A team of Army-funded scientists from Purdue did just that with the development of tiny holograms—smaller than the width of a human hair!—made by shining lasers through a metasurface. This could change display… » 11/15/13 5:40pm 11/15/13 5:40pm

Group Sues EPA For Not Regulating Nano-Silver Pollution

Fed up by government inaction, a consumer safety… » 5/04/08 5:30pm 5/04/08 5:30pm

British Navy Working on Developing Invisible Ships Using Metamaterials

Scientists at the Britannia Royal Navy College are working hard to make the idea of an invisible ship a reality using metamaterials that refract light in such a way that it "bends" around an object, making it appear as if it were invisible. This would only account for viewing with the naked eye however—naturally radar… » 3/03/08 8:00pm 3/03/08 8:00pm
