It's a bit odd that the feature doesn't perhaps support Safari and Opera, both of which are fairly HTML5-friendly, but it's a nice time saver for serious YouTube users in any case.

Nicholas Fang, a mechanical science and engineering professor at the University of Illinois, lead the development of the device, which is made of 16 concentric rings of acoustic circuits. Sound waves find their way into the channels between the circuits, moving faster toward the innermost rings. But as this speeding up requires energy, the waves instead gather on the outer rim of the cloak, essentially bending the sound waves around itself and hiding anything inside it.
In testing, the cloak made objects of various shapes and sizes acoustically invisible to sound waves from 40 to 80 KHz, though further refinements need to be made for faster moving objects. Still, Fang is pleased with his progress. "This is certainly not some trick Harry Potter is playing with," he explained. Oh? Bummer. [Paper via Daily Tech and Phys Org]

Who will build the fastest experimental helicopter?
The very thing that makes the helicopter a marvel of maneuverability—a rotor that generates both lift and propulsion—also makes it an airborne plodder. As a helicopter gains speed, the rotor blades encounter more drag and require more power to cut through the air. Complicating matters, the blade moving into the wind generates more lift than the blade moving away from the wind. This creates an imbalance known as lift dissymmetry that can cause the helicopter's nose to pitch upward and result in violent shaking, which is, of course, counterproductive to breaking speed barriers.
Sikorsky's answer is the X2, an experimental chopper that last year unofficially broke the helicopter speed record of 216 knots (249 mph), set in 1986 by the Westland Lynx ZB500. The X2 features two main rotors and replaces the conventional tail rotor with a propeller. The rotors spin in opposite directions to counteract each other's torque and balance the upward forces acting on each blade. The tail prop, meanwhile, helps the rotors push the three-ton X2 through the sky, letting the rotors spin at a safer speed and dedicate more energy to lifting the craft than moving it forward.
In September, Eurocopter unveiled its own potential record-breaker, the X3, which takes a very different approach. Instead of a tail prop, the helicopter distinguishes itself with a pair of wing-mounted propellors. In this configuration, the rotor can spin at even slower speeds and stick to what it does best—creating lift—while the propellors generate forward thurst and speed. In March, Eurocopter will put the X3 through its next round of testing, when it is expected to reach speeds of up to 220 knots (253 mph).
Is a rivalry brewing? Both companies claim to have evaluated and rejected their competitor's approach during initial planning. "We are the only one aiming at validating the concept of a cost-effective high-speed helicopter," says Jean-Michel Billig, the vice president of R&D at Eurocopter. The names of the prototypes certainly suggest a spirit of one-upmanship. Although Billig calls the choice of X3 "coincidence," Chris Van Buiten, the director of Sikorsky Innovations, says jokingly, "We'll name our next one the X-Bajillion to make sure we win the grade-school naming contest."
To be fair, neither company invented the idea of supplementing, or even replacing, propulsion from the rotor. In 1963 Bell Helicopter strapped twin turbojet engines to a modified YH-40 Iroquois, which reached speeds of over 274 knots (315 mph). It also gobbled fuel.
Balancing extra weight and speed with increased fuel demand will be a challenge for each company as they advance their designs. Eurocopter remains secretive about its next steps, but Sikorsky is aiming for the military market first; Van Buiten says it plans to produce an armed version of the X2, called the X2 Raider, by 2014.

Philips LED lightning saves energy, money, lives
In addition to the Philips flood lights we reviewed recently, the "health and well-being" innovator offers a complement of lighting at lower wattages. The AmbientLED 12.5W A-Shape indoor bulb replaces the most common incandescent in use today, using less energy than a 60-watt A19 bulb and lasting over eight times as long at a savings of $140 over its lifetime.
The AccentLED candle is ideal for use in sconces and other decorative fixtures, and lasts up to 10 years using less energy than a typical 15-watt incandescent candle.
Finally, the AccentLED mini reflector in both MR16 and GU10 models, is designed for use in track lighting and recessed ceiling fixtures. These three-watt options replace equivalent standard 20-watt and 35-watt halogen bulbs, respectively, at over eight times the life and a savings up to $96 over that span. Intended to highlight objects at close range, the inherent heat- and UV-free properties of Philips LEDs mean that plants, art, wall hangings and fabrics won't be affected by the fading, dehydrating and scorching common with incandescent lights.
Native to all Philips LEDs is instant activation, quiet operation and solid-state construction at one-third the CO2 emissions of standard bulbs. They even warn you when they're dying, fading rather than burning out abruptly. Combine that with the lives saved by reducing the incidence of stepstool stumbles and we can all finally afford to stop living by cell phone light.
Make the Great Light Switch and Save
The flute was created on an Objet Connex500 rapid prototyper, a 3-D printer that can print in multiple materials at the same time. The flute was constructed from a few different materials – a rigid material for the body, a softer one for the mouthpiece, another for sealing the air in at the proper places – during a print run of about 15 hours, during which time the materials were added on one thin layer at a time.
The finished product was in four pieces, which simply had to be rinsed of supporting materials and assembled by hand (the springs were the only element added after printing). It's not a perfect flute just yet – as you'll see in the video below, there is still some fine tuning to be done – but it does produce good acoustic sounds. Moreover, it heralds just how far 3-D printing technology has come over the last couple of decades.
