Atmospheric 'Sunshade' Could Reduce Solar Power Generation
The concept of delaying global warming by adding particles into the upper atmosphere to cool the climate could unintentionally reduce peak electricity generated by large solar power plants by as much as one-fifth, according to a new NOAA study. The findings appear in this week's issue of Environmental Science and Technology. view more (2009-03-12)
Device Burns Fuel with Almost Zero Emissions
Georgia Tech researchers have created a new combustor (combustion chamber where fuel is burned to power an engine or gas turbine) designed to burn fuel in a wide range of devices — with next to no emission of nitrogen oxide (NOx) and carbon monoxide (CO), two of the primary causes of air pollution. view more (2006-06-22)
Scientists find safer ways to detect uranium minerals
The threat of 'dirty' bombs and plans to use nuclear power as an energy source have driven Queensland University of Technology scientists to discover a new, safer way of detecting radioative contamination in the ground. view more (2006-11-22)
Jules Verne ATV given its 'wings'
The next time Jules Verne ATV's four solar arrays are fully deployed, giving the vehicle a total span of 22.3 m, will be in early 2008, at 28 000 km/h over the South Pacific Ocean. view more (2007-12-03)
Study: Elderly Women Can Increase Strength But Still Risk Falls
Elderly women can increase muscle strength as much as young women can, a new study from the University of New Hampshire finds, indicating that decline in muscle function is less a natural part of the aging process than due to a decline in physical activity. view more (2008-10-24)
New Milestone in Fuel Cell Development - Double World Record with the SOFC
Scientists at Research Centre Juelich report an important step forward in the international race to develop efficient high-temperature fuel cells. A fuel cell stack put into operation in mid April consisting of just 40 single planar cells delivered a power of 9.2 kilowatts at an average operating temperature of 850°C with hydrogen as the fuel... view more...

Rethinking what men and women want in a partner
When it comes to romantic attraction men primarily are motivated by good looks and women by earning power. At least that's what men and women have been saying for a long time. Based on research that dates back several decades, the widely accepted notion permeates popular culture today. view more (2008-02-14)
Flower power
A plastic "energy flower'' that collects solar and wind energy that can then be used to power appliances in the home for free has won a Northumbria University student a top award. Paul Richardson, a third year design student, won a £1,750 Design International Attachment Award from the RSA (Royal Society for the encouragement of Arts,... view more... (2002-05-24)
New advances in detection and identification technology from Oxford University
Increasingly, industry demands technologies that enable detection and identification of targets, ranging from information for traffic tolling and airspace management to patient supervision in hospitals, security passes and stock control. Researchers at Oxford University's Department of Engineering Science have developed new retroreflectors that... view more... (2002-07-01)
Models of eel cells suggest electrifying possibilities
Engineers long have known that great ideas can be lifted from Mother Nature, but a new paper by researchers at Yale University and the National Institute of Standards and Technology (NIST) takes it to a cellular level. view more (2008-10-03)
UT Houston researchers say pediatric carbon monoxide poisoning linked to video games after Hurricane Ike
Hours after Hurricane Ike roared ashore in Texas, more than two million homes were without power, which left some scrambling to preserve food and others looking for ways to entertain children, a move that proved to be, in some instances, poisonous. view more (2009-05-27)
Laser Blasts Viruses in Blood
A father-son research team working from separate laboratory benches across the country has discovered a new use for lasers - zapping viruses out of blood. The technique, which holds promise for disinfecting blood for transfusions, uses a low-power laser beam with a pulse lasting just fractions of a second. view more (2007-09-05)
Rubber 'snake' could help wave power get a bite of the energy market
A device consisting of a giant rubber tube may hold the key to producing affordable electricity from the energy in sea waves. view more (2008-07-07)
NIST discovers how strain at grain boundaries suppresses high-temperature superconductivity
Researchers at the National Institute of Standards and Technology (NIST) have discovered that a reduction in mechanical strain at the boundaries of crystal grains can significantly improve the performance of high-temperature superconductors (HTS). view more (2009-06-18)
Earthquakes in the sky
AN AFTERNOON shower in London may have more in common with an earthquake in California than you`d think, because both processes obey similar statistical rules. The scientists who discovered the link say thinking about rain as a kind of "earthquake in the sky" may help improve models of the weather. ... view more... (2002-05-01)
Step on the gas — New fuel cell design adds control, reduces complexity
When Princeton University engineers want to increase the power output of their new fuel cell, they just give it a little more gas - hydrogen gas, to be exact. view more (2007-01-17)
Free-electron laser shines at over 14 kilowatts in the infrared
The most powerful tunable laser in the world just shattered another power record: the Free-Electron Laser (FEL), supported by the Office of Naval Research and located at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility (Jefferson Lab), produced a 14.2 kilowatt (kW) beam of laser light at an infrared wavelength of 1.61... view more...

Space technology keeps Nuna II ahead of the pack
The Nuon Solar Team look set to beat their own world record for driving a sun-powered car across Australia in the World Solar Challenge. At the end of day 3 Nuna II, despite two flat tires, finished half an hour ahead of its closest competitors. Nuna II, raced by the Nuon Solar Team, and aided by ESA space technology, reached Cadney Homestead,... view more... (2003-10-21)
Nuclear Power Worldwide: Status and Outlook
Nuclear power's prominence as a major energy source will continue over the next several decades, according to new projections made by the International Atomic Energy Agency (IAEA), which has just published a new report, Energy, Electricity and Nuclear Power for the period up to 2030. view more (2007-10-24)
