Light

Researchers have shown that that exposure to one color of light can increase pain sensitiv...

In research that could lead to improved treatment of chronic and debilitating pain conditions, scientists at Stanford Bio-X have shown that pain sensitivity in genetically modified mice can be altered by shining different colors of light on their paws.  Read More

One of the flexible, stretchable optical interconnections

If flexible electronic devices are ever going to become practical for real-world use, the circuitry incorporated into them will have to be tough and resilient. We're already seeing progress in that direction, including electrical wires that can still carry a current while being stretched. However, what if the application calls for the use of fiber optics? Well, scientists from Belgium may have that covered, too. They've created optical circuits utilizing what they believe are the world's first stretchable optical interconnections.  Read More

Israeli artist Liat Segal has created a device that uses light to print fading messages onto photosensitive paper. The Confession Machine uses ultraviolet (UV) LEDs that are programmed to switch on and off at certain intervals in order to print people's confessions onto paper coated with a UV sensitive pigment. Then they disappear.  Read More

Bioglow's Starlight Avatar plants emit faint light similar in intensity to starlight – hen...

Ever thought the glowing forests from the movie Avatar were pretty cool and wanted one yourself? Bioglow is the latest company to attempt to put such autoluminscent plants in homes with its aptly named Starlight Avatar.  Read More

A breakthrough by EPFL researchers could improve the data throughput of worldwide optical ...

As the volume of data carried around the world via optical fibers continues to increase, researchers at the Swiss Federal Institute of Technology in Lausanne (EPFL) have found a way to increase data throughput capacity by ten times. Because it is based on changing the shape of light pulses to reduce the space between, the breakthrough would work on existing optical fiber infrastructure.  Read More

Scientist have created a new form of matter by coaxing photons to interact with each other...

Scientists from Harvard and MIT have jointly demonstrated that, in specific conditions, photons can be made to interact with each other and form molecules. Such groupings of photons, dubbed “Photonic molecules”, constitute an entirely new form of matter, which until recently was purely theoretical. Combining the properties of light and those of solids, in terms of physics this new form of matter is not unlike a certain material that millions of Star Wars fans are already well familiar with. Lightsaber material.  Read More

While one would hope to make an invisibility cloak that performs like the central image, i...

It's often a case of swings and roundabouts. If you save money by buying a house out of town, you spend more time and money commuting. If you really measure the momentum of an electron, you have no idea where the little guy is located. And now, according to a new analysis by a pair of University of Texas electrical engineers, the better an object is hidden by an invisibility cloak at a given wavelength of light, the easier it is to see at other wavelengths. Swings and roundabouts.  Read More

SmartLight could direct light from outside (far right), through a building, and to a centr...

Researchers at the University of Cincinnati have developed technology that could help cut lighting energy costs by brightening up rooms with natural light. The SmartLight system is designed to direct sunlight into dark, dingy rooms located within the bowels of buildings without requiring the installation of new wiring, ducts, tubes or cables. It also allows excess light to be harnessed and centrally stored to provide energy for electric lighting on cloudy days.  Read More

The SEIL LED grid signaling system installed in a bag

Cyclists wanting to notify other road users of stopping or turning intentions can use their arms, but it's not always convenient or safe to do so. Bike-based blinking technology like the Spooklight system is a good way to go, but having to detach and carry your lights between rides to keep them out of the hands of opportunist thieves can be a bit of a pain. A sleeker idea would be to integrate a wirelessly-controlled lighting system into your backpack? That's precisely what SEIL from Myung Su Lee does. Bright directional arrows, stopping signals or custom animated text messages shine through the fabric at the back of the bag at the press of a button on a bar-mounted wireless controller.  Read More

A Lumitrack sensor-equipped controller is used to control an on-screen airplane

Motion-tracking systems like Wii and Kinect have certainly changed the way we play video games – among other things – but some people still complain that there's too much of a lag between real-world player movements and the corresponding in-game movements of the characters. The creators of the experimental Lumitrack system, however, claim that it has much less lag time than existing systems ... plus it's highly accurate and should be cheap to commercialize.  Read More
