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 …
YOU might think it would be difficult for a terrorist to obtain genes from the smallpox virus, or a similarly vicious pathogen. Well, it’s not. Armed with a fake email address, a would-be bioterrorist could probably order the building blocks of a deadly biological weapon online, and receive them by post within weeks. That’s the …
A Stanford University research team has designed the first microscope sensitive enough to track the real-time motion of a single protein down to the level of its individual atoms. Writing in the Nov. 13 online issue of the journal Nature, the Stanford researchers explain how the new instrument allowed them to settle long-standing scientific debates …
Bionic Arms are controlled via the patient thinking and having the impulse picked up via sensors on his check nerves
Self-contained power plants could supply growing energy demand in poor countries is discussed in a MIT technology review article. This year’s Nobel Peace Prize laureate, Mohamed ElBaradei is a proponent of small nuclear reactors. In a talk at MIT last week he cited a new report from the International Energy Agency that said world energy …
