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 …

100 mbps internet speed over existing copper lines

A european research project, Eureka 3051 virtual fiber , has successfully trialed 10 Mbps symmetrical internet speed for 28000 people over existing copper cable lines. Local businesses in the trial were able to obtain 50 MB/s symmetrical data connectivity. The technology has subsequently been developed to provide 100 MB/s connectivity and has already been sold …

Design for optical light frequency invisibility shell

Purdue University engineers, following mathematical guidelines devised in 2006 by physicists in the United Kingdom, have created a theoretical design, to make something invisible to one visible light frequency, that uses an array of tiny needles radiating outward from a central spoke. Creating the tiny needles would require the same sort of equipment already used …

Update on Pan Starrs- Asteroid detector

Four 71-inch mirrors gathering light for Pan-STARRS would each be hooked up to what would be the four largest digital cameras ever built. The system would be able to survey the entire sky once a week, and would be able to detect asteroids as small as 1,000 feet across. They face opposition from environmentalists who …

Pioneers of Environmentalism now support nuclear energy as part of solution

Patrick Moore, co-founder of Greenpeace, is chairman and chief scientist of Greenspirit Strategies in Vancouver, British Columbia, and is co-chair of an industry-funded initiative, the Clean and Safe Energy Coalition, which supports increased use of nuclear energy. He indicates that nuclear energy should be part of the environmental solution and that coal and fossil fuel …

50 nm metallic stamping process

Creating high-resolution metallic interconnects is an essential part of the fabrication of microchips and other nanoscale devices. Researchers at the University of Illinois at Urbana-Champaign have developed a simple and robust electrochemical process for the direct patterning of metallic interconnects and other nanostructures. Fang said the newly created “S4 process” uses a patterned superionic material …
