LEDs are already vaunted as an energy-efficient technology for lighting, but new research shows that their efficiency can be increased by a factor of two. A paper describing the work shows that the secret is to decrease the number of defects in the gallium nitride (GaN) films used to create LEDs by incorporating cleverly placed
Want a computer that is functional as soon as you hit the power button (no lag time)? Wish that those enormous server farms didn’t gobble quite as much energy? You’re in luck! Researchers have developed a new device that should enable both of these things. The trick? Combining two memory functions into a single device.
Medieval studies scholars are embarking on an effort that, if successful, should make it easier for future scholars to study the past. Ironically, medieval studies experts were among the first to incorporate the use of modern technology into their research (Rev. Roberto Busa used punchcards in 1949 as part of his research on St. Thomas
When it comes to science and technology, it appears that people don’t actually dislike the things they say they dislike. At the very least, a new study shows, people don’t dislike those things as much as they think they do. The fault, dear reader, lies not in ourselves, but in our polls. The study, published
Everyone hates traffic. Everyone also hates car accidents. What if there was a traffic pattern that could cut travel times at busy intersections by 20 percent, and cut collision-related injures by over 60 percent? Good news – there is! The pattern is called, fittingly enough, a superstreet. The superstreet concept has been around for 20
