Supercompressed silicon and hydrogen superconducts at room temperature

A new superconducting material fabricated by a Canadian-German team has been fabricated out of a silicon-hydrogen compound [after supercompression, 96-120GPa] and does not require cooling. They had to keep the material under pressure (100GPa) in order to get it to superconduct. CORRECTION: The press release talked about not using refrigerant and EEtimes said room temperature …

Computational protein design has developed enzymes from scratch

In a major step forward for computational protein design, University of Washington scientists have built from scratch a handful of enzymes that successfully catalyze a specific chemical reaction. These proteins have no naturally occurring counterparts, and the reaction–which breaks down a man-made chemical–has no natural catalyst. David Baker and his colleagues at the University of …

Texas Instruments and MIT make microchip ten times more energy efficient

Researchers at MIT and Texas Instruments (TI) (NYSE: TXN) today unveiled a new chip design for portable electronics that can be up to ten times more energy-efficient than present technology. The design could lead to cell phones, implantable medical devices and sensors that last far longer when running from a battery in about five years …

DNA used to assemble and glue a 3D structure of one million 15 nm gold nanoparticles

DNA was used to build a three-dimensional structure out of 15 nanometer gold nanoparticles. The gold nanoparticles are the bricks and the DNA is scaffold and mortar. Three-dimensional nanoparticle arrays are likely to be the foundation of future optical and electronic materials. The novel part of the work is that the researchers use DNA to …

China’s climate change and nuclear plans

A report that I had missed before. The Yomiuri newspaper reported (May, 2007) that China plans to boost its nuclear power generation capacity to between 15 and 20 times its current level by the end of 2030. Yomiuri Shimbun. The National Development and Reform Commission, which administers China’s energy policy, plans to increase nuclear power …

Silicon electronics can be printed by Ink Jet printers

Kovio, sunnyvale startup, jas the world’s first all-printed silicon transistor capability. They will have roll to roll printing of computers. This is clearly a process that will get even better as the design rules shrink and as they use faster printing technology like Memjet This technology also has implications for better fabbers, rapid prototyping and …

New Inkjet printer with dots with 100 times better resolution

A new type of inkjet printer has been developed that can precisely print dots of various materials just 250 nanometers in diameter, while regular inkjet printers have 25 micron dots. The inkjet printer could make it possible to rapidly synthesize complex nanoscale structures out of various materials. This is part of a wave of new …

Discovery of first gene that specifically links calorie restriction to longevity

Loss of only one of the genes, a gene encoding the protein PHA-4, negated the lifespan-enhancing effect of calorie-restriction in worms. And, when researchers undertook the opposite experiment—by overexpressing pha-4 in worms—the longevity effect was enhanced. “PHA-4 acts completely independent of insulin/IGF-1 signaling and turns out to be essential for CR-mediated longevity,” says Panowski. “We …
