Diffuse optical tomography could offer a safer alternative to fMRI and PET scans (Photo: T...

When doctors want to monitor someone's brain activity, they generally use either functional magnetic resonance imaging (fMRI) or positron emission tomography (PET). One subjects the patient to strong magnetic fields, while the other involves radiation exposure. Scientists at Washington University in St. Louis, however, have recently had success using diffuse optical tomography (DOT). Although it may look kind of extreme, it basically just involves shining LEDs into the subject's head.  Read More

The Cree T8 is an LED tube designed to replace conventional fluorescent tubes

Fluorescent lights aren't on the top of many people’s favorites list. Ever since they were introduced at the New York World’s Fair in 1939, they've been notorious for their cold, bluish light that is the definition of “uncomplimentary” and accompanied by flickering and a telltale buzz. Cree, Inc. is aiming to relegate fluorescent tubes to the pages of history with its new T8 series of LED tubes that promise LED-level energy savings and greatly improved light quality.  Read More

Lunecase runs off of electromagnetic energy emitted by the iPhone

Smartphone cases are so common that you can pick one up at the supermarket checkout stand, so for one to stand out, it needs something more than a print of a cartoon kitten. Built by Concepter, a company based in Kiev, Ukraine, the Lunecase is s a batteryless, wireless phone case that not only interacts with an iPhone, but also powers itself from the electromagnetic radiation emitted by the device.  Read More

The Drumstooled combines a kick drum, reversed pedal and height-adjustable stool

France's Patrice Bardin has come up with a stylish and eye-catching twist on self-accompaniment. Rather than stomp out a backbeat on a kick drum, home-made rhythm board or even an empty suitcase out front while thumping the strings of a battered acoustic guitar and throwing out soulful vocals, the Drumstooled is a mash up of a stool and an acoustic kick drum, with some colorful LED lighting thrown in for good measure.  Read More

Cylo is a brand of urban bicycle that's completely new to the market, and its creators are so confident they've brought together the right mix of ingredients that they're claiming Cylo is the "ultimate urban bicycle."  Read More

The new Philips clear LED bulb

It's no secret that LED bulbs are far more efficient than traditional incandescent lights. One drawback, though, is a different look than the bulbs that people are accustomed to. Philips has just launched a new clear LED bulb that features the traditional light bulb shape and look, but with the efficiency benefits of modern offerings.  Read More

The unobtrusive nature of SnapRays adds weight to its creator's claim as a convenient repl...

Placing guidelights up your hallway or down your staircase can involve bulky plugin solutions or a professional and expensive installation. SnapRays Guidelight, an easy-install outlet cover with built-in LEDs, could simplify this process by turning any standard power outlet into a night light without the need for re-wiring or batteries.  Read More

A rendering of one of the two-dimensional LEDs

In regular microchips, work is performed via the movement of electrons within the chip. Thanks to the recent creation of the thinnest-ever LEDs, however, such chips may one day be able to use light instead of electrons, saving power and reducing heat. Of course, those LEDs could also just be used as a really flat form of lighting, in any number of applications.  Read More

Gallium nitride transistors enabled the compact design of this 2090 lumen retrofit LED lam...

Although known for long life and low energy consumption, the LED uses a DC power supply, or driver, to overcome its sensitivity to current fluctuations, and it’s the high-frequency, high-speed switching transistors in this driver that’s made the LED so costly for use in large-scale commercial applications dominated by fluorescent and incandescent lighting. But that’s about to change. Fraunhofer researchers are developing a new, more economical means of making the high-performance gallium nitride transistors needed for the LED’s high-efficiency driver.  Read More

The app-based system determines the shopper's location via the flickering of the overhead ...

Wondering where your local supermarket keeps its whole wheat flour? Soon, an app on your smartphone may be able to guide you to it – with a little help from the store's overhead LED lights, and technology developed by Philips.  Read More
