A new low-cost flat panel light source with extremely low power consumption could lead to ...

Researchers at Tohoku University in Japan have developed a new low-cost flat panel light source that could pioneer a new generation of brighter, cheaper and greener lighting devices to rival LEDs. The device uses arrays of highly conductive carbon nanotubes to deliver evenly-distributed illumination with high efficiency and a power consumption as low as 0.1 Watts – about 100 times lower than that of light-emitting diodes.  Read More

Thomas Edison may have invented the lightbulb, but he never received the Nobel Prize for it. Isamu Akasaki and Hiroshi Amano at the University of Nagoya, and Shuji Nakamura working at Nichia Chemicals in Tokushima, Japan have proven more successful, being awarded the 2014 Nobel Prize in Physics for their invention of the blue LED, which is the key to modern energy-efficient lighting.  Read More

Eton's Blackout Buddy H2O is small and stowable

It's the big paradox of emergency-use flashlights ... by the time you eventually need to use them, their batteries have died. Eton's new Blackout Buddy H2O, however, will reportedly still work after sitting for up to 10 years. And to turn it on, you just add water.  Read More

A rolled film of the material – the roll is about one tenth the diameter of a human hair

With its incredible strength, chemical stability, high thermal conductivity and low electrical resistance, it's no wonder that graphene is finding more and more uses. Soon, however, it may be facing some competition from molybdenum di-sulphide – a thin metallic film that can emit light.  Read More

Scientists have been observing the wave-particle duality of light for centuries, but never has light been seen to behave like matter. Until now, that is. Researchers at Princeton University have devised a method for giving light the properties of liquids and solids, with huge potential ramifications in the study of quantum mechanics and other areas of physics.  Read More

The ultra-thin terahertz band light detector can see just below the surface of clothing, b...

A new prototype light detector uses graphene's light-absorbing properties to see in a broad band of light wavelengths that includes terahertz waves. These fall between the microwave and infrared bands, thereby making it possible to look just beneath the surface of opaque objects such as skin and plastic.  Read More

Researchers at Rice University's Laboratory for Nanophotonics (LANP) have developed a new image sensor that mimics the way we see color by integrating light amplifiers and color filters directly onto the pixels. The new design enables smaller, less complex, and more organic designs for CMOS (complementary metal-oxide semiconductor) sensors and other photodetectors used in cameras.  Read More

The Qudos Action light, mounted alongside a GoPro Hero 3 White edition camera

We've seen a plethora of accessories for the GoPro Hero actioncam cropping up over the past few years, including everything from stabilizers to drones to helmet-mounted poles. Surprisingly, though, except for scuba-specific models, there's been almost nothing in the way of lights. Australian bike gadget manufacturer Knog recently set out to fill that void, by releasing its Qudos Action light earlier this month. I recently had a chance to get my hands on the thing, and liked what it had to offer.  Read More

An illustration of an air waveguide, with the four laser-produced 'holes' (orange) and the...

Efficient as fiber optic cables are at transmitting data in the form of light pulses, they do need to be physically supported, and they can only handle a finite amount of power. Still, what's the alternative ... just send those focused pulses through the air? Actually, that's just what scientists at the University of Maryland have already demonstrated in their lab.  Read More

The smart forfour and fortwo enter their third generation with a new design and new engine...

Since being introduced in 1998, over 1.5 million of the smart fortwo city cars have been produced. The company has now revealed the third-generation, with the new fortwo and forfour models boasting a colorful new design, a range of modern engines and turning circles tight enough to take on the narrowest city streets.  Read More
