Green Spirit Creations saw an opportunity to create environmentally-friendly products usin...

UK-based Green Spirit Creations is the latest team to try its hand at paper-based lighting solutions. Seeking out discarded materials from local shop-owners, its stylish household lamps are made from 100 percent recycled cardboard (bulbs, wiring and switches aside).  Read More

New research could help shift workers at travelers reset their body clock faster (Image: S...

The human body clock is the curse of any shift worker or traveler arriving in a new time zone. Although one's body clock can be adjusted by external cues, such as light – a factor that devices such as the Re-Timer and Litebook are designed take advantage of – the adjustment period can vary significantly for different people. Now researchers have discovered the mechanism that controls how easily such adjustments can be made.  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

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

The Confession Machine uses UV LEDs to print disapearing messages onto photosensitive pape...

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
