Researchers at Cornell University have created a palm-sized device that uses water tension as a switchable adhesive bond and can support many times its own weight. The device could usher in a whole new generation of superheroes by allowing shoes or gloves that stick and unstick to walls on command, or see the creation of Post-It notes that can bear loads.

Single-atom transistor promises new quantum computing breakthroughs
14:42 December 6, 2009 PST
As far as transistor size is concerned, it doesn't get any smaller than this. An international group of researchers from the Helsinki University of Technology, the University of New South Wales and the University of Melbourne have successfully built a fully working transistor that is just one atom in size, smashing previous records and, more importantly, creating a very unique venue to study phenomena to be exploited in the rapidly developing field of quantum computing.

Light resonators used to move nano-sized objects
22:55 November 19, 2009 PST
Scientists at Cornell University report they can now use a light beam carrying a single milliwatt of power to move objects and even change the optical properties of silicon from opaque to transparent at the nanometric scale. Such an advancement could prove very useful for the future of micro-electromechanical (MEMS) and micro-optomechanical (MOMS) systems. Read More
'Time telescope' speeds up optical transmission by 27 times
22:17 October 4, 2009 PDT
Most of today's telecommunication data is encoded at a speed of 10 Gbit/s, but researchers are constantly looking for new ways to push this limit even further. A group of researchers at Cornell University have recently come up with the "time telescope," a sophisticated system that can speed up optical communication by 27 times to an outstanding 270 Gbits/s by squeezing more information into a single flash of light and that, unlike previous solutions, does so in an energy-efficient manner.

Carbon nanotubes used to build a near-ideal efficiency solar cell
04:34 September 14, 2009 PDT
Today's photovoltaic technology, while certainly promising, offers very poor efficiency because of inherent issues in its working mechanism. Using carbon nanotubes, however, Cornell University researchers now hope to lead the way to the next generation of highly efficient solar panels. Read More
