Tiny, implantable medical device can propel itself through bloodstream

Posted: 22 Feb 2012 06:42 AM PST

For 50 years, scientists had searched for the secret to making tiny implantable devices that could travel through the bloodstream. Engineers have now demonstrated a wirelessly powered device that just may make the dream a reality.

New twist on nanowires: Technology can control composition and structure of these tiny wires as they grow

Posted: 22 Feb 2012 06:42 AM PST

Nanowires -- microscopic fibers that can be "grown" in the lab -- are a hot research topic today, with a variety of potential applications including light-emitting diodes and sensors. Now, researchers has found a way of precisely controlling the width and composition of these tiny strands as they grow, making it possible to grow complex structures that are optimally designed for particular applications.

Recharge your cell phone with a touch? New nanotechnology converts body heat into power

Superbugs from space offer new source of power

Posted: 21 Feb 2012 06:26 PM PST

Scientists have created a "designer slime" that can double the electrical output of existing microbial fuel cells. Bacillus stratosphericus -- a microbe commonly found in high concentrations in the stratosphere orbiting Earth with the satellites -- is a key component of a new 'super' biofilm.

Dubai April 20-27, 2012
HANDS ON LEARNING • EXCLUSIVE PHOTO OPS • DIGITAL REVIEW SESSIONS
The adventure never stops, especially when we travel to the Arabian desert. Explore the dunes on an off-road vehicle and take in a camel caravan against the arid landscape as the sun sets. Enjoy a Bedouin dinner in the desert, complete with a belly dancer. A day trip to the East Coast takes us through spectacular mountain scenery, a local market, a picturesque fishing village, and lunch by the Indian Ocean. We will end this exciting trek on a high note-literally!-with an early morning hot-air-balloon ride, photographing from high above as the sun greets the desert landscape.

Wireless power could revolutionize highway transportation

Posted: 01 Feb 2012 09:07 AM PST

A research team has designed a high-efficiency charging system that uses magnetic fields to wirelessly transmit large electric currents between metal coils placed several feet apart. The long-term goal of the research is to develop an all-electric highway that wirelessly charges cars and trucks as they cruise down the road.

Only the lowest carbon dioxide emitting technologies can avoid a hot end-of-century

Posted: 16 Feb 2012 06:50 AM PST

Could replacing coal-fired electricity plants with generators fueled by natural gas bring global warming to a halt in this century? What about rapid construction of massive numbers of solar or wind farms, hydroelectric dams, or nuclear reactors -- or the invention of new technology for capturing the carbon dioxide produced by fossil-fueled power plants and storing it permanently underground? A research team calculated the expected climate effects of replacing the world's supply of electricity from coal plants with any of eight cleaner options.
