(Phys.org) —A trio of researchers working in France, along with a colleague from the U.K. has re-measured the gravitational constant using the same apparatus they built 12 years ago and have found a small change. In their ...
(PhysOrg.com) -- For the first time, researchers have measured a long-theorized force that operates at distances so tiny they’re measured in billionths of a meter, which may have important applications in nanotechnology ...

(Phys.org) —A team of researchers in Europe has come up with a new way to determine the gravitational constant G. Rather than relying on using torque based techniques to measure gravitational pull, the researchers instead ...
Piezoelectric ultrasonic motors have two significant advantages, namely their high energy density and their simple structure, which both contribute to their miniaturization. We have built a prototype micro ultrasonic motor ...

(Phys.org) —Researchers at the Italian Institute of Technology with funding from the European AMARSI project have built the first passive compliant robot that features both arms and legs. Passive compliant robots are those ...
(PhysOrg.com) -- Audi has unveiled its new electric car concept, the Audi e-tron at the 2009 Frankfurt Motor Show in Germany.
(Phys.org)—Are we moving closer to a computer age where "touchscreen" is in the room, but it is the counter, desktop, wall, our new digital work areas? Are we moving into a new form factor called Anywhere? Do we understand ...
Information processing technologies that are typically based on electron charges can also theoretically make use of the electric spin. Magnon spintronics can harness quantized spin waves, magnons, as carriers of spin currents ...
A simple but accurate theory of how sound interacts with small particles has been developed by theoretical physicists at RIKEN. This advance will help to improve the manipulation of microparticles by sound.
