Scientists at the University of Adelaide, Australia, have put the squeeze on light. By discovering that light within optical fibers can be squeezed into much tighter spaces than was previously believed possible, the researchers at the University's Institute for Photonics and Advanced Sensing (IPAS) have claimed a breakthrough that could change the world's thinking on light’s capabilities, especially when it comes to its use in telecommunications, such as fiber-to-the-home (FTTH), computing and other light sources.

Scientists at the University of Tokyo have found a curious way to translate drawings and three-dimensional shapes into music. The prototype laser-based musical instrument known as scoreLight uses 3D tracking technology to generate real-time sounds based on the shapes and colors it encounters along the way, transforming doodling into a truly synthesized experience.

Spica is the brightest star in the constellation of Virgo and also the inspiration for this visual loudspeaker lamp system where sound vibrations force illuminated liquid within a transparent tube to dance to the music and makes the spectrum analyzer on my hi-fi appear somewhat dull by comparison.

Light normally bounces off obstacles in its way, and the part of the beam that is reflected back and captured by our eyes contributes to our perception of the world around us. However, every reflection dissipates a small part of the beam's energy, and can eventually weaken it significantly. A team of MIT researchers have developed an innovative waveguide that allows microwave light to travel one way only and without reflections, paving the way to much more efficient lightwave circuits and connections.

Though it may not make it into everyone’s ‘top ten’ list of most desirable technological developments, replacing the spaghetti-junction of wires that typically gathers behind a desk or workspace would undoubtedly be a welcome advance. Wireless peripherals are helping the situation somewhat and wireless power will be a massive boon once perfected but, in the meantime, we’re looking to technologies like optical cables to handle high-volume data transfer. Intel’s recent research in this area should be of particular interest, since it’s designed to replace or augment connections used in consumer-based electronics, such as USB2.0, HDMI, Firewire, DVI and the like.

Reading at night can be problematic. Firstly, there can be arguments in bed between partners – one who wants to sleep with the light off, the other who wants to read with a light on. Then there’s the issue of inadequate bedside lighting or the shadows on your pages cast by an overhead light. Well, if you wear glasses, the Nachteule (night owl) light may help solve your night-time reading problems. Read More

So what do you do when you challenge yourself to come up with a design to make traveling around busy, congested cities as easy and stress-free as possible? According to the folks behind the YikeBike - which was officially launched at Eurobike 2009 trade fair in Friedrichshafen Germany this month - you start with a blank sheet of paper, throw a good-sized front wheel in for stability, swap pedals for a brushless electric motor and abandon the familiar forward-leaning riding position of the bicycle altogether.

Breakthroughs are coming thick and fast – or should that be thin and fast – in the field of nanoscale lasers. It wasn’t even a month ago that we reported on the development of a laser emitting 'metal-semiconductor-metal sandwich', made up of a semiconductor as thin as 80 nanometers laying between 20-nanometer dielectric layers. But now researchers at the University of California, Berkeley, have reached a new milestone in laser physics by creating the world's smallest semiconductor laser, capable of generating visible light in a space smaller than a single protein molecule.

Harnessing the unique properties of metamaterials, researchers in China have recently published a work detailing the implementation of a thin air, broadband and remotely controllable 'invisible gateway' that is able to shield all types of electromagnetic waves while letting through all other physical objects.
