Tiny ion pump sets new standard in cooling hot computer microchips
University of Washington researchers have succeeded in building a cooling device tiny enough to fit on a computer chip that could work reliably and efficiently with the smallest microelectronic components.
Swan system to help blind navigate environment
Imagine being blind and trying to find your way around a city you've never visited before - that can be challenging for a sighted person. Georgia Tech researchers are developing a wearable computing system called the System for Wearable Audio Navigation (SWAN) designed to help the visually impaired, firefighters, soldiers and others navigate their way in unknown territory, particularly when vision is obstructed or impaired.
Insects inspire robotics research
Insects are proving invaluable for one researcher at the University of Alberta, who hopes robots can perform the same types of tasks that ants or bees do.
Deep-sea oil rigs inspire mit designs for giant wind turbines
An MIT researcher has a vision: Four hundred huge offshore wind turbines are providing onshore customers with enough electricity to power several hundred thousand homes, and nobody standing onshore can see them. The trick? The wind turbines are floating on platforms a hundred miles out to sea, where the winds are strong and steady.
Desktop printing of carbon nanotube patterns
Using an off-the-shelf inkjet printer, a team of scientists has developed a simple technique for printing patterns of carbon nanotubes on paper and plastic surfaces. The method, which is described in the August 2006 issue of the journal Small, could lead to a new process for manufacturing a wide range of nanotube-based devices, from flexible electronics and conducting fabrics to sensors for detecting chemical agents.
Nanowire 'barcode' system speeds biodetection in the field
Detecting biowarfare agents in the field will become a lot easier thanks to a new barcode system based on biosensing nanowires developed by Lawrence Livermore National Laboratory (LLNL) researchers.
Plasma assisted engines fuel efficient, cleaner
Gasoline, diesel, and turbine engines could soon burn cleaner or be more fuel efficient through the application of Plasma Assisted Combustion, a technology originated and developed at Los Alamos National Laboratory, and now poised to enter the marketplace.
Acoustic data may reveal hidden gas, oil supplies
Just as doctors use ultrasound to image internal organs and unborn babies, MIT Earth Resources Laboratory researchers listen to the echoing language of rocks to map what's going on tens of thousands of feet below the Earth's surface.
Engineers forge greener path to iron production
MIT engineers have demonstrated an eco-friendly way to make iron. The new method eliminates the greenhouse gases usually associated with iron production.Darfur is headed for a disaster unless the Sudanese Government changes its mind and allows a force of United Nations peacekeepers to take over from the existing African Union (AU) operation in the strife-torn region, Secretary-General Kofi Annan said today
A new window into the deformation of nanoscale materials
Materials on the nanoscale don't always have the same properties they would in bulk; for one thing, nanomaterials are often a lot harder. Unlike most bulk materials, a crystal that is small enough can be perfect, free of defects, capable of achieving strength near its ideal theoretical limit.Darfur is headed for a disaster unless the Sudanese Government changes its mind and allows a force of United Nations peacekeepers to take over from the existing African Union (AU) operation in the strife-torn region, Secretary-General Kofi Annan said today

Researchers announce invention of the optofluidic microscope
The old optical microscopes that everyone used in high-school biology class may be a step closer to the glass heap. Researchers at the California Institute of Technology have announced their invention of an optofluidic microscope that uses no lens elements and could revolutionize the diagnosis of certain diseases such as malaria.
Undersea gliders making waves as valuable new tool in marine research
The Pacific Ocean constantly throws challenges in the face of marine scientists, from hypoxia-caused marine "dead zones" to unusual patterns of ocean upwelling that have changed the migratory behavior of Pacific Northwest salmon. But Oregon State University researchers are making use of a new tool that is better helping them understand the world's vast oceans – undersea gliders that patrol the waters of our coasts and record critical data. These gliders differ from other autonomous underwater vehicles – or AUVs – because they lack propellers or tethers.
New device may improve vision and mobility for people with tunnel vision
Scientists at Schepens Eye Research Institute, an affiliate of Harvard Medical School, say a visual aid they invented promises to improve the visual abilities of people with tunnel vision.
Nanoscientists create biological switch from spinach molecule
Nanoscientists have transformed a molecule of chlorophyll-a from spinach into a complex biological switch that has possible future applications for green energy, technology and medicine.
Using microbes to fuel the u.s. hydrogen economy
"If the U.S. is to have a future hydrogen-based economy, we'll need a way to generate abundant quantities of hydrogen safely and economically," said Daniel (Niels) van der Lelie, a biologist at the U.S. Department of Energy's Brookhaven National Laboratory.
Engineers build a better battery – with plastic
Brown University engineers have created a new battery that uses plastic, not metal, to conduct electrical current. The hybrid device marries the power of a capacitor with the storage capacity of a battery.
Scientists and engineers simulate jet colliding with World Trade Center
Researchers at Purdue University have created a simulation that uses scientific principles to study in detail what likely happened when a commercial airliner crashed into the World Trade Center's North Tower on Sept. 11, 2001.
On airplanes, fiber optics poised to reach new heights
In an effort to provide safer and more reliable components for aircraft, researchers have invented an optical on-off switch that can replace electrical wiring on airplanes with fiber optics for controlling elevators, rudders, and other flight-critical elements.
Energy does grow on trees
Road warriors, it may be time to hug a tree. In a few years, you could find yourself filling your gas tank with ethanol derived from specially bred black cottonwood trees — and at prices not seen since the 1990s.
Ceramic microreactors developed for on-site hydrogen production
Scientists at the University of Illinois at Urbana-Champaign have designed and built ceramic microreactors for the on-site reforming of hydrocarbon fuels, such as propane, into hydrogen for use in fuel cells and other portable power sources.
