Zyvex has interesting nanostructured materials planned

The Center for Responsible Nanotechnology talks about an interesting project that Zyvex has planned. They will create nanostructures with elements of molecular precision. This will help enable more powerful capabilities for controlling structures. The plans are to use silicon and silicon carbide and possibly other materials and created connected layers. Brian WangBrian Wang is a …

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 …

Study Of Living Cells Could Revolutionize The Way We Test Drugs

An optical microscope image of a yeast cell (the round feature to the right) on top of the micron-sized detector used in the studies. The image is blurred because the cell is so small that large magnification is required in order to obtain the image. (Credit: Image courtesy of Engineering and Physical Sciences Research Council) …

Nanofibers thinner than critical diameters have more strength

Scientists at the Technion-Israel Institute of Technology have shown that tiny polymer nanofibers become much stronger when their diameters shrink below a certain size. Their research, published in the January issue of Nature Nanotechnology, could make possible stronger fabrics that use less material. Professor Eyal Zussman and Dr. Oleg Gendelman of the Faculty of Mechanical …
