If you apply an electric voltage across two water-filled beakers and separate them, something strange happens: The water stretches from beaker to beaker, creating a bridge that defies gravity. Water bridges were discovered 120 years ago, but no one has ever been sure why they do not collapse. One theory is that the voltage makes the water molecules line up, creating a “dielectric” tension that stops the bridge from falling. Another argues that surface tension—the tendency of a water’s surface to shrink inwards—keeps the bridge aloft.
Now, researchers believe that water bridges rely on both strategies. Reza Namin at the Sharif University of Technology in Tehran and colleagues measured various parameters across the length of a water bridge, including voltage, current, and bridge diameter. Then they plugged the data into a computer simulation to calculate the forces involved. The results, to be published next month in Physical Review E, reveal that dielectric tension and surface tension each carry about half a water bridge’s weight. The results, the researchers believe, could help engineers develop electrowetting, a method of using electricity to adjust the adhesion of fluids to a screen that is expected to be used in the next generation of e-book readers.

Haworth and Obscura Digital's digital whiteboard can hold 160 acres of virtual space-
Apple (AAPL) has rolled out smaller models of its iPad. Jeff Reuschel is thinking bigger. The global design director for office-furniture maker Haworth, in partnership with interactive display company Obscura Digital, has created a touchscreen that covers a conference-room wall. Like a supersize version of CNN’s (TWX) Magic Wall, Bluescape displays a unified image across 15 linked 55-inch flat-screen monitors, each equipped with 32 specialized sensors to read users’ hand movements. Unlike whiteboards or flip charts, it won’t require much erasing or page turning: When zoomed out as far as possible, the digital board’s virtual space totals 160 acres. Using Bluescape, corporate and university clients can store often scattershot brainstorming sessions in perpetuity. Co-workers or classmates can add digital sticky notes, either with a digital pen on the wall itself or by uploading documents from other devices, from which they can also browse the virtual space. “There are fewer and fewer people working in cubicles,” says Reuschel. “The old-fashioned vertical surfaces are going away.”

Exoskeleton arm can lift up to 50 lb, is controlled by handheld remote
Most engineering senior design projects are an entertaining, but lack the wow factor of corporate inventions. But every once in a while you'll come across a gem.
I. Titan Arm Looks to Smash Back Problems
Among the pleasant surprises from this semester was the "MEAM Team" from the University of Pennsylvania, who offered up their own take on an upper body exoskeleton. The team was motivated by the very real problem of back disorders which affect 600,000 workers a year in the U.S. and cost the economy an estimated $50B USD. Most of these back disorders come from overexertion during lifting.
That's where the "Titan Arm" comes in.
The one-arm exoskeleton helps the user lift objects in a curl motion, sparing the user's elbow from wear and tear.
Composed of five structural members, four moveable joints, and an adjustable upper arm member, the exoskeleton is strapped on the back and onto the user's arm. The shoulder has three degress of freedom, so the user's arm is able to move relatively naturally in three-dimensional space.
