(PhysOrg.com) -- Extremely small nanoscale particles are released by common kitchen appliances in abundant amounts, greatly outnumbering the previously detected, larger-size nanoparticles emitted by these appliances, according to new findings by researchers at the National Institute of Standards and Technology. So-called "ultrafine particles" (UFP) range in size from 2 to 10 nanometers. They are emitted by motor vehicles and a variety of indoor so... More

(PhysOrg.com) -- Scientists at the National Institute of Standards and Technology have developed a radical new method of focusing a stream of ions into a point as small as one nanometer. Because of the versatility of their approach—it can be used with a wide range of ions tailored to the task at hand—it is expected to have broad application in nanotechnology both for carving smaller features on semiconductors than now are possible and for nondes...

(University of Chicago) University of Chicago scientists have induced electrons in the nanocrystals of semiconductors to cool more slowly by forcing them into a smaller volume. This has the potential to improve satellite communications and the generation of solar power. Slowing down the cooling of these electrons -- in this case, by more than 30 times -- could lead to a better infrared laser source and increase the bandwidth of communication satel... More

A landmark national survey on the use of nanotechnology for "human enhancement" shows widespread public support for applications of the new technology related to improving human health. However, the survey also shows broad disapproval for nanotech human enhancement research in areas without health benefits. A team of researchers at North Carolina State University and Arizona State University (ASU) conducted the study, which could influence the dir... More

Nanoparticles that are one milliard of a metre in size are widely used, for example, in cosmetics and food packaging materials. There are also significant amounts of nanoparticles in exhaust emissions. However, very little is yet known of their health effects, because only a very small portion of research into nanoparticles is focused on their health and safety risks. Nanoparticles have even been dubbed the asbestos of the 2000s bys some researche... More

DNA strands with attached chromophores along their length can perform at nanonscale fiber optic cables, using a new technique developed by resarchers at Chalmers University of Technology in Gothenburg, Sweden.The wires self-assemble and can self-repair: if a chromophore is damaged and falls free of the DNA strand, another will readily take its place.

The world may be witnessing the final stages of a 50-million-year transition from a planet with a persistent warm climate and scant polar ice to one with greatly expanded ice sheets at both poles, two climatologists suggest in Nature.The Nature paper goes on to propose that humans, as long as they have a technologically powerful society, would be likely to avert such a slide into a long big chill by adding greenhouse gases to the atmosphere.

Intel warned on Wednesday that its sales could fall as much as 19 percent in the fourth quarter. Other major players in the chip industry, including Applied Materials and National Semiconductor, offered their own bleak outlooks.The gloomy forecasts suggest that the technology industry is about to enter a slump that will rival or possibly exceed the dot-com bust of 2001.
