The team at ETH Zurich tested a single and double magnet setup to see which works better for robotic capsule self-assembly. The hope is to eventually construct a self-assembling, surgical robot that can investigate the intestines.
The modules stay securely linked by the magnets at the ends of the capsules.
Swimmer Ariana Kukors presses her fingers into a device built to measure the force she generates with her freestyle kick. (She doesn't hold on to anything.) The red vertical line shows the amount of force at a point in time. Kukors's kick is strong and consistent, which is why the wave signal generally has the same amplitude throughout the recording.
A new chip design could lead to far cheaper large-area electronics.
The director of the new Massachusetts-based Microsoft Research lab wants to use mathematics to design better search engines, recommendation systems, and online auctions.
The biggest physics experiment ever, CERN's new particle accelerator, goes live this summer.
Photosynth is still a work in progress. It is dazzling, but what is it for?
Digital artists are using game technologies to create bold new works.
Combining massive quantities of data, insights into human psychology, and machine learning can help manage surprising events, says Eric Horvitz.
Krishna Palem thinks a little uncertainty in chips could extend battery life in mobile devices--and maybe the duration of Moore's Law, too.
