Scientists have developed a new way to create electromagnetic Terahertz (THz) waves or T-rays - the technology behind full-body security scanners. The researchers behind the study, published recently in the journal Nature Photonics, say their new stronger and more efficient continuous wave T-rays could be used to make better medical scanning gadgets and may one day lead to innovations similar to the 'tricorder' scanner used in Star Trek.

A year ago, it was just a fledgling Kickstarter project. Now Kogeto has VC funding and a spot on Apple Store shelves. LAS VEGAS—As far as Kickstarter success stories go, Kogeto, a start-up exhibiting at this year's Consumer Electronics show, has a pretty outstanding one.

(PhysOrg.com) -- Everyone knows that the LED market is huge, it’s among other things, the technology behind our big screen TVs. That’s why so many companies are investing so much money in trying to find ways to improve on it so that as our TVs get bigger, they won’t grow out of the average consumer’s price range. Now, Samsung, the Korean technology giant, has announced that one of its research teams has figured out a way to grow crystalline gallium nitride (GaN) LEDs on regular glass.

Coming to a city near you soon: By adding giant flywheels to subway systems, cities are able to harness the power created by thousands of braking trains, using it to accelerate other trains or feeding it back into the grid. Every time a train starts and stops, it draws or dissipates several megawatts of energy, enough to power more than a thousand homes. This happens thousands of time per day, every day, in commuter rail systems across the country.

Move over Juvederm and Restalyne. Make way for a new skin filler. Johns Hopkins researchers say they have improved the technology on popular injectable hyaluronic gels that gloriously restored skin’s volume and wiped away wrinkles -- but sagged or faded away after about a year

X rays are so common today you probably never stop to think about them. They help check a broken wrist, a sprained ankle, the state of our teeth. But a little more than a century ago, x ray machines provided a revolution in medicine, allowing doctors to look inside the body.
