Efficiency boost makes solar cells more affordable
Solar energy could become more affordable following a breakthrough by UNSW scientists, who have boosted the efficiency of solar cell technology. view more (2007-05-03)
Surveillance vehicles take flight using alternative energy
Nearly undetectable from the ground, unmanned aerial vehicles (UAVs) are widely used by the military to scan terrain for possible threats and intelligence. Now, fuel cell powered UAVs are taking flight as an Office of Naval Research (ONR)-sponsored program to help tactical decision-makers gather critical information more efficiently- and more... view more...

Team develops energy-efficient microchip
Researchers at MIT and Texas Instruments have unveiled a new chip design for portable electronics that can be up to 10 times more energy-efficient than present technology. The design could lead to cell phones, implantable medical devices and sensors that last far longer when running from a battery. view more (2008-02-05)
How stereotypes can lead to success
Stereotypes can boost as well as hinder our chances of success, according to psychologists from the University of Exeter and St Andrews University. Writing in the new edition of Scientific American Mind (out in the UK 22 April 2008), they argue that the power of stereotypes to affect our performance should not be underestimated. view more (2008-04-22)
New Carbon Material Shows Promise of Storing Large Quantities of Renewable Electrical Energy
Engineers and scientists at The University of Texas at Austin have achieved a breakthrough in the use of a one-atom thick structure called "graphene" as a new carbon-based material for storing electrical charge in ultracapacitor devices, perhaps paving the way for the massive installation of renewable energies such as wind and solar... view more...

Compound removes radioactive material from power plant waste
Strontium 90 is a common radioactive by-product of fission in nuclear power plants. When extracted from the reactor along with other isotopes, a mixture is created made up of the radioactive material and inert ions like sodium and calcium. view more (2008-03-13)
The Effect of Gamma Waves on Cognitive and Language Skills in Children
New studies conducted by April Benasich, professor of neuroscience at Rutgers University in Newark, and her colleagues reveal that gamma wave activity in the brains of children provide a window into their cognitive development, and could open the way for more effective intervention for those likely to experience language problems. view more (2008-10-22)
MIT: engine on a chip promises to best the battery
MIT researchers are putting a tiny gas-turbine engine inside a silicon chip about the size of a quarter. The resulting device could run 10 times longer than a battery of the same weight can, powering laptops, cell phones, radios and other electronic devices. view more (2006-09-26)
Vise squad: Putting the squeeze on a crystal leads to novel electronics
A clever materials science technique that uses a silicon crystal as a sort of nanoscale vise to squeeze another crystal into a more useful shape may launch a new class of electronic devices that remember their last state even after power is turned off. view more (2009-05-11)
Keeping an eye on fatigue in wind turbines
Wind farms are springing up everywhere like mushrooms. Business in this alternative sector of the energy industry is booming, thanks in part to federal and former state subsidies. The total output of the wind turbines installed in Germany today is theoretically enough to supply the whole capital of Berlin with electricity. But the durability of... view more... (2003-09-18)
Shifting the world to 100 percent clean, renewable energy as early as 2030 -- here are the numbers
Most of the technology needed to shift the world from fossil fuel to clean, renewable energy already exists. Implementing that technology requires overcoming obstacles in planning and politics, but doing so could result in a 30 percent decrease in global power demand. view more (2009-10-20)
With double frequency to deeper blue
Light transports data at high speed over fibre-optic networks. Light measures and creates images of large and small objects in scanners and microscopes. Light writes information onto all sorts of recording media and surfaces. The best-quality light is produced by lasers, which have meanwhile become an indispensable tool - not only in medicine and... view more... (2003-07-01)
Carnegie Mellon researchers look at fossil fuel impacts
A team of Carnegie Mellon University researchers report that the choices U.S. officials make today could limit how the nation's future energy needs are met and could cost consumers billions in idle power plants and associated infrastructure systems. view more (2007-08-23)
ECM launches Agroscan ultrasound veterinary devices for pregnancy detection
ECM of France has launched Agroscan - a complete range of ultrasound scanners for veterinary use, suitable for performing ultrasounds on sows, cows, mares, ewes and goats. The Agroscan L is completely innovative as it is the only portable device to use both sector and linear probes. view more (2005-04-07)
Is our heritage no longer crumbling? Weathering rates of St. Paul’s Cathedral London have halved in the last ten years in line with cleaner air.
SUMMARY: Measurements of the rates of weathering on St. Paul’s Cathedral, London have halved in the last ten years (1990 - 2000) as compared with the previous ten years (1980 - 1990). Yearly averages of sulphur dioxide concentrations in the air decreased from around 25 parts per billion (ppb) in the early 1980’s to... view more... (2000-08-30)
Bad vibes - solving a problem for research and industry
An inexpensive method of damping harmful torsional vibration in rotating drive systems has been developed at Max Planck Institute of Plasma Physics (IPP) in Garching and submitted for patent. The method was devised in the context of fusion research but is universally applicable - wherever machines in energy technology and process engineering are... view more... (2003-11-14)
Diamonds are a laser's best friend
Tomorrow's lasers may come with a bit of bling, thanks to a new technology that uses man-made diamonds to enhance the power and capabilities of lasers. view more (2009-09-21)
A new brake on cellular energy production discovered
A condition that has to be met for the body to be able to keep warm, move and even survive is that the mitochondria - the cells' power stations - release the right amounts of energy. view more (2007-07-27)
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. view more (2006-09-20)
Don't blame cities for climate change, see them as solutions
Cities are being unfairly blamed for most of humanity's greenhouse gas emissions and this threatens efforts to tackle climate change, warns a study in the October 2008 issue of the journal Environment and Urbanization. view more (2008-09-29)
