Auto-focus eyeglasses rely on liquid lenses

University of Utah graduate student Nazmul Hasan is the first to admit that the glasses he helped design may not look cool. But what these prototypes lack in style, they make up for in smart design. An app will download one’s eyeglass prescription to the frames. From then on, the specs will focus on whatever the wearer looks at, such as a phone text.

Voila! The text will come into focus. — Stephen Ornes

Cool Jobs: Reaching out to E.T. is a numbers game

Searching for aliens may sound like science fiction. Yet for many scientists, it has become serious business. In the second of a three-part series, we meet three researchers using math in their quest to find other living beings in our universe. One is calculating the likelihood of finding life on other planets. Another is trying to figure out where best to beam a “hello” to E.T. The third is looking for a common language with extraterrestrials — and it will probably be numbers. — Ilima Loomis
