University of California, Los Angeles researchers have created a carbon nanotube-based artificial muscle that heals itself and generates electricity.As the material contracts after an expansion, the rearranging of the carbon nanotubes generates a small electric current that can be captured and used to power another expansion or stored in a battery.The self-healing muscle is also energy efficient, conserving about 70 percent of the energy put into ...

California Institute of Technology, University of North Carolina at Chapel Hill and Ghent University researchers are making progress in developing broadly applicable, nanoparticle-enabled siRNA anticancer therapeutics.They found that siRNA-containing nanoparticles deliver the siRNA to tumors more effectively when the nanoparticle are targeted to the tumor. They also found that the targeted nanoparticles effectively penetrated lung metastases, did ... More

Video footage has been transmitted experimentally (22 meters) using a terahertz wireless signal for the first time, by Terahertz Communications Lab in Braunschweig, Germany.Using terahertz bandwidth -- which ranges from 300GHz to 3 terahertz (THz) -- could offer a 1000 fold increase in transmission speed and should open up new frequencies for communication. The as yet untapped terahertz band of the electromagnetic spectrum lies between microwaves ... More

A modern computer contains two different types of components: magnetic components, which perform memory functions, and semiconductor components, which perform logic operations. A University of Missouri researcher, as part of a multi-university research team, is working to combine these two functions in a single hybrid material. This new material would allow seamless integration of memory and logical functions and is expected to permit the design o... More

Bristol University researchers have demonstrated the world's smallest optical controlled NOT gate--the building block of a quantum computer--fabricated from silica wave-guides on a silicon chip.The team generated pairs of photons, each encoding a quantum bit or qubit of information. They coupled these photons into and out of the millimeter-sized chip, using optical fibers.Quantum optical circuits have typically relied on large optical elements, wi... More

An "artificial cell" capable of synthesising genes and making them into proteins quickly and cheaply has been developed by MIT researchers.(David Kong/MIT)The first part of the device synthezises the genes using enzymes to join together DNA strands from a pool of short templates. The finished genes are then copied to produce many versions of the final product. Cycles of heating and cooling control the enzymes carrying out the reactions.Once the ge... More

University of Illinois at Urbana-Champaign researchers have made stretchable and flexible silicon and plastic integrated circuits that are just one crystal--1.5 microns--thick.The circuits are designed so that the plastic, not the silicon, absorbs most of the stress when the chips are bent. Until now, integrated circuits have been limited by use of much thicker, brittle silicon wafers. (Source: http://technology.newscientist.com/article/dn13546-... More

University of Maryland physicists have found that graphene conducts electricity at room temperature with less intrinsic resistance than any other known material.Graphene, a new material that combines aspects of semiconductors and metals, is one of the materials being considered as a potential replacement for silicon for future computing. The very high mobility of graphene would allow for transistors that must switch extremely fast.The low resisti... More

Researchers at University of California, Berkeley have manipulated stem cells in older muscle tissue to produce new muscle fibers at levels comparable to young stem cells.Old muscle tissue produces elevated levels of the molecule TGF-beta, which is known to inhibit muscle growth. The researchers used RNA interference, which can silence specific genes, to inhibit the TGF-beta pathway in old mice.Muscle wasting--loss of muscle mass--occurs both duri... More

Two researchers--a former Los Alamos National Laboratory engineer and an Alabama A&M University researcher--have developed highly efficient nanotube-based tile materials that can convert radiation, not heat, from nuclear materials into electricity.The tiles are made of carbon nanotubes packed with gold and surrounded by lithium hydride. Radioactive particles slamming into the gold push out a shower of high-energy electrons that pass into the lithi... More

Massachusetts General Hospital researchers have found that low doses of hydrogen sulfide (smell of rotten eggs) can safely and reversibly produce a suspended-animation-like state in mice.The gas depressed both metabolism and heart rate, but did not change heartbeat strength or blood oxygen levels. It could be used to preserve organ function in situations with limited oxygen supply, such as after a traumatic injury.Massachusetts General Hospital Ne... More

Engineers at Polytechnic University of Valencia have designed a metamaterial that redirects sounds and could be used in buildings to shield them from noises. The sound-shielding material comprises arrays of sonic crystals, which, if made, would be the first acoustic cloaking device. It could also be useful in hiding military ships and other vessels from sonar. (Source: http://www.technologyreview.com/Nanotech/20912/)
