Highlights from Interbike 2014

Light

The Defender runs on three AA batteries, and incorporates watertight silicone gaskets

People who commute by bicycle don't have to remove their pedals, racks or fenders when they park in public ... so why should their lights be any different? Well, because most battery-operated bike lights come off with the simple flick of a quick-release, or the turning of a single bolt. Massachusetts-based Gotham Bicycle Defense Industries, however, is attempting to address that problem with its Defender bike light. Not only is it theft-resistant, but it's also waterproof, and it looks like the light Dirty Harry would use - if he rode a bike.  Read More

The NAO is Petzl's first headlamp to use Reactive Lighting

In addition to two powerful LED lights, the new NAO headlamp from Petzl has a light sensor. The headlamp doesn't just shine light, it measures ambient light to provide the ideal amount of output. It also uses a few other smart design features to give you a high-performing, convenient headlamp.  Read More

Virtual photons bounce off a 'mirror' that vibrates at almost the speed of light. The roun...

A perfect vacuum is impossible to achieve, at least in theory. As anyone with any interest in quantum physics would know, the vacuum is full of various particles that fluctuate in and out of existence. These "virtual" particles have been the focus of scientist, Christopher Wilson. Working with his team at Sweden's Chalmers University of Technology, Wilson has succeeded in producing real photons from these virtual photons. Which, in layman's terms, means that they have created measurable light ... from nothing.  Read More

The Philips bio-light is 'powered' by glowing bioluminescent bacteria

The search for greener, more power-efficient lighting systems won't stop with compact fluorescents and LED systems if Dutch electronics giant Philips has anything to say about it. In an effort to embrace a truly natural approach to lighting, the company took a cue from fireflies and deep-sea creatures to create a (literally) green light powered not by electricity or sunlight, but by glowing bioluminescent bacteria.  Read More

Scientists have discovered that objects coated with a forest of carbon nanotubes can be ma...

Although Klingon-style disappearing spaceships may not be in our neighborhood any time soon, the technology that could allow a spaceship to vanish from sight may be here now. Scientists from the University of Michigan have successfully made a three-dimensional etched silicon image of a tank appear as a featureless black void, that completely blended in with the backdrop surrounding it. The secret: good ol’ carbon nanotubes.  Read More

Scientists from the OPERA project are reporting that new experiments confirm their earlier...

On September 23rd, researchers from the European OPERA project made the now-famous announcement that they had observed neutrinos traveling faster than the speed of light. Given that Einstein's special theory of relativity states that nothing can travel faster than the speed of light, their proclamation was naturally met with some skepticism – various physicists stated that there was likely a flaw in the design, implementation or calculations involved the experiment. To their credit, the OPERA collaborative made a point of inviting other scientists to try to replicate their results. In the meantime, however, they’ve replicated those results themselves, and announced today that neutrinos still appear to be the speediest particles in the universe.  Read More

The Valkee is a device that its makers claim can treat seasonal affective disorder, by shi...

Many readers in the Northern Hemisphere are likely already starting to experience seasonal affective disorder, appropriately enough known as SAD. For those people fortunate enough not to be familiar with it, SAD is a mood disorder that is brought on by the shorter day-length experienced in winter – less sunlight results in gloomier people. One of the most common treatments involves regular exposure to bright artificial lights, that appear to psychologically serve the same purpose as sunlight. Now, one might assume that such light therapy would require that people see the light. According to the Finnish designers of the Valkee device, however, light also does the trick if you shine it up your ears.  Read More

The new super-black coating made from hollow carbon nanotubes prevents reflection because ...

When it comes to gathering measurements of objects so distant in the universe that they can no longer be seen in visible light, the smallest amount of stray light can play havoc with the sensitive detectors and other instrument components used by astronomers. Currently, instrument developers use black paint on baffles and other components to help prevent stray light ricocheting off surfaces, but the paint absorbs only 90 percent of the light that strikes it. NASA engineers have now developed a nanotech-based coating that absorbs on average more than 99 percent of the ultraviolet, visible, infrared, and far-infrared light that hits it, making it promising for a variety of space- and Earth-bound applications.  Read More

So, you’re looking at that one photo you took, and wishing that the flower in the foreground was in focus instead of the person behind it? Well it’s no big deal, just go in and shift the focus. Oh yeah, that’s right, you can’t ... but you will be able to soon. California-based Lytro, Inc. announced today that its consumer light field camera is now available for preorder, and should be shipping early next year. It is the first camera of its kind made for the general public.  Read More

Last year researchers at Imperial College London proposed that along with being used to cloak physical objects metamaterials could also be used to cloak a singular event in time. A year later, researchers from Cornell University have demonstrated a working "temporal cloak" that is able to conceal a burst of light as if it had never occurred.  Read More
