In a new experiment, published last week in Science, Jay Groves and colleagues at the University of California at Berkeley designed an artificial membrane that allows them to begin to answer how receptors on t-cells effect and control immune system response. The membrane has proteins that are constricted in a specific region. When receptors on …
The discs, developed by InPhase Technologies, based in Colorado, US, hold 300 gigabytes of data and can be used to read and write data 10 times faster than a normal DVD. The company, along with Japanese partner Hitachi Maxell announced earlier in November that they would start selling the discs and compatible drives from the …
It seems that bubbles of electrons lined up in ultracold liquid helium could be used to build a quantum computer capable of carrying out a staggering 10 to the 30th power simultaneous calculations. To make an electron bubble, start with liquid helium that has been cooled below 2.17 kelvin so that it behaves like a …
New Research Enabling Tool: Researchers at the EPFL (Ecole Polytechnique Federale de Lausanne) have developed a new machine that can reveal how electrons behave inside a single nano-object. The results from initial tests on pyramidal gallium-arsenide quantum dots are presented in an article in the November 24 issue of Nature. The machine developed by Professor …
Now a trio of Brown University researchers, led by engineering and physics professor Jimmy Xu, has made the impossible possible. The team has created the first directly pumped silicon laser. They did it by changing the atomic structure of silicon itself. This was accomplished by drilling billions of holes in a small bit of silicon …
A Lux Research article divides nations are into four categories. The details are discussed at soft machines. Dominant (USA, Japan, Germany and South Korea) – strong both in basic research and commercialisation, Ivory Tower (UK and France), strong in basic research but weaker in commercialisation, Niche Players (Israel, Singapore and Taiwan), weaker in basic research …
Francesca Moresco and colleagues at Freie University in Berlin said the interaction between the tip of a STM and atoms or molecules bound to a surface can be used to construct impressive nanostructures, such as the quantum corral. The researchers said they combined STM manipulation techniques with the ability of a molecule to assemble nanostructures …
By coating the surfaces of tiny carbon nanotubes with monoclonal antibodies, biochemists and engineers at Jefferson Medical College and the University of Delaware have teamed up to detect cancer cells in a tiny drop of water The work is aimed at developing nanotube-based biosensors that can spot cancer cells circulating in the blood from a …
Researchers at the University of Washington have found a genetic pathway linking nutrient response and the aging process, they report in the Nov. 18 issue of the journal Science. The UW researchers conducted a genome-wide screen of yeast cells to find which genes, and their corresponding proteins, affect lifespan. Two of the proteins, called Tor1 …
Researchers from Penn State, Rice University, and the University of Oregon demonstrated that single-molecule switches can be tailored to respond in predictable and stable ways, depending on the direction of the electric field applied to them The research is the latest achievement in the team’s ongoing studies of a family of stiff, stringy molecules known …
IBM Corp. unveiled Thursday (Nov. 17) what is said is the world’s first electroluminescent nanotube transistor and claimed it glows 1,000 times brighter than a light-emitting diode with as much as 10,000 times more photon flux. By emitting thousands of photons in silicon with the same energy expenditure as one photon in gallium arsenide, IBM …
