Engineers invent a noninvasive technique to correct vision

Nearsightedness, or myopia, is an increasing problem around the world. There are now twice as many people in the US and Europe with this condition as there were 50 years ago. In East Asia, 70 to 90 percent of teenagers and ...

Researchers develop flexible, stretchable photonic devices

Researchers at MIT and several other institutions have developed a method for making photonic devices—similar to electronic devices but based on light rather than electricity—that can bend and stretch without damage. ...

Exotic quantum states made from light

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are sufficiently concentrated and cooled. The individual particles ...

Electrons in graphene behave like light, only better

A team led by Cory Dean, assistant professor of physics at Columbia University, Avik Ghosh, professor of electrical and computer engineering at the University of Virginia, and James Hone, Wang Fong-Jen Professor of Mechanical ...

Engineering discovery brings invisibility closer to reality

Since the beginning of recorded time, humans have used materials found in nature to improve their lot. Since the turn of this century, scientists have studied metamaterials, artificial materials engineered to bend electromagnetic, ...
