Foresight’s Technology roadmap for productive nanosystems to be revealed Oct 9, 2007 Arlington

by

The Technology Roadmap for Productive Nanosystems has examined what can be developed in labs today and then mapped out a step-by-step plan for the pathways of development that must take place to achieve productive nanosystems. This has been a long anticipated event by those (like myself) who follow molecular nanotechnology. Here is the Technology Roadmap …

Nanoparticles are 400% more active Catalysts : could make cheaper Fuel Cells

by

Nanoparticles with a completely new shape may lead to cheaper catalysts that could make many experimental-energy technologies more practical. Nano geometry: This 24-sided platinum nanoparticle could lead to cheaper alternative energy. Credit: Zhong Lin Wang, Georgia Tech The 24-sided platinum nanoparticles have surfaces that show up to four times greater catalytic activity compared with commercial …

Discovery of first gene that specifically links calorie restriction to longevity

by

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 …

Better prostate cancer test

by

A far more accurate blood test for prostate cancer has been created The American Cancer Society projects that in 2007 there will be 219,000 new cases and 27,000 deaths. Yet detecting the disease early has always been problematic. The new tests accuracy: about 3 percent of the time, when the test was positive, there was …

Nanoscale power generator improved over a thousand fold

by

About a year ago, Zhong Lin Wang of Georgia Tech in the US discovered that, when he disturbed zinc oxide nanowires, they gave off a tiny electrical current, a phenomenon called piezoelectricity. At the time, he had to use the tip of an atomic force microscope – a $250,000 instrument – to create about one-billionth …
