Researchers control surface tension to manipulate liquid metals Posted: 15 Sep 2014 12:39 PM PDT Researchers have developed a technique for controlling the surface tension of liquid metals by applying very low voltages, opening the door to a new generation of reconfigurable electronic circuits, antennas and other technologies.

Elusive quantum transformations found near absolute zero Posted: 15 Sep 2014 12:36 PM PDT To isolate quantum fluctuations that define the properties of a metallic material, scientists probed it at temperatures colder than interstellar space. The research provides new methods to identify and understand promising new materials, including superconductors.

Run, cheetah, run: New algorithm enables cheetah robot to run and jump, untethered, across grass Posted: 15 Sep 2014 08:45 AM PDT Speed and agility are hallmarks of the cheetah: The big predator is the fastest land animal on Earth, able to accelerate to 60 mph in just a few seconds. As it ramps up to top speed, a cheetah pumps its legs in tandem, bounding until it reaches a full gallop.

Scientists come closer to the industrial synthesis of a material harder than diamond Posted: 15 Sep 2014 07:21 AM PDT Researchers have developed a new method for the synthesis of an ultrahard material that exceeds diamond in hardness. The material is an ultrahard fullerite, a polymer composed of fullerenes, or spherical molecules made of carbon atoms.

Rolling 'neat' nanotube fibers: Acid-free approach leads to strong conductive carbon threads Posted: 15 Sep 2014 06:58 AM PDT The very idea of fibers made of carbon nanotubes is neat, but scientists are making them neat -- literally. The single-walled carbon nanotubes in new fibers line up like a fistful of uncooked spaghetti through a new process.
