Absorbent materials for the storage of hydrogen
A research team from the Public University of Navarra has started a study of the design and development of absorbent materials that enable the storage of hydrogen, a clean fuel that can be used as an alternative to those derived from fossil fuels, such as petrol and diesel.   view more (2005-06-28)

Biofuels: An advisable strategy?
Biofuels have been an increasingly hot topic on the discussion table in the last few years. In 2003 the European Union introduced a Directive suggesting that Member states should increase the share of biofuels in the energy used for transport to 2% by 2005 and 5.75% by 2010.   view more (2007-03-08)

Photocell Provides Both Heat And Electricity
In 1969, scientists at the Ioffe Physico-Technical Institute, St. Petersburg made heterostructured photoelectric cells based on the elements of the third and the fifth group of the periodic table (for example, gallium arsenide). Now the photocells can find application not only in space, but also on... view more (2001-11-27)

Makeshift medicine at a distance
In the October Journal of Telemedicine and Telecare, Australian doctors describe a unique case study of a boy in a remote part of Queensland who was badly burnt and needed specialist care from a burns centre over 1100km away. Using a desktop scanner hooked up to the family computer, the boy`s... view more (2002-09-24)

Vulcain 2 engine now in full production
A small ceremony took place yesterday at the site of Snecma Moteurs in Vernon, France, to mark the beginning of industrial production of the Vulcain 2 engine, designed for the new Ariane 5 ECA and Ariane 5 ES ATV launchers.   view more (2005-04-05)

U-M scientists simulate effects of blowing Mars dust
Gusting winds and the pulsating exhaust plumes from the Phoenix spacecraft's landing engines could complicate NASA's efforts to sample frozen soil from the surface of Mars, according to University of Michigan atmospheric scientist Nilton Renno.   view more (2007-06-18)

Laboratory scientists study soot in megacity pollution
A team of Los Alamos scientists recently returned from a month-long data-gathering trip to Mexico City as part of an international, multi-agency environmental science collaboration.   view more (2006-05-09)

"Springer" - A Solution To Water Pollution?
A faster, more efficient way of tracking water pollution and carrying out environmental surveys is being developed. Work has begun to build "Springer", an unmanned surface vehicle (USV) that will be able to operate in shallow water.    Funded primarily by the Engineering... view more (2004-04-05)

Traffic exhaust can cause asthma, allergies and impaired respiratory function in children
Children exposed to high levels of air pollution during their first year of life run a greater risk of developing asthma, pollen allergies, and impaired respiratory function.   view more (2008-04-10)

Aerodynamic trailer cuts fuel and emissions by up to 15%
Creating an improved aerodynamic shape for truck trailers by mounting sideskirts can lead to a cut in fuel consumption and emissions of up to as much as 15%. Earlier promising predictions, based on mathematical models and wind tunnel tests by TU Delft, have been confirmed during road tests with an... view more (2008-04-18)

Killer pulses help characterize special surfaces
Detecting deadly fumes in subways, toxic gases in chemical spills, and hidden explosives in baggage is becoming easier and more efficient with a measurement technique called surface-enhanced Raman scattering. To further improve the technique's sensitivity, scientists must design better scattering... view more (2008-07-30)

Ladybirds Turn Black Living In Town
Researchers from the Institute of Common Genetics, Russian Academy of Sciences, have analyzed Russian and foreign materials collected for more than a century and have compared them with their own observations in towns and preserves in recent years. It has turned out that black mutants, melanists,... view more (2003-06-27)

NASA satellite measures pollution from east Asia to North America
In a new NASA study, researchers taking advantage of improvements in satellite sensor capabilities offer the first measurement-based estimate of the amount of pollution from East Asian forest fires, urban exhaust, and industrial production that makes its way to western North America.   view more (2008-03-18)

Palladium and platinum an easier find with Pitt researcher's detection method
Finding uses for palladium and platinum--rare precious metals coveted by the automobile, chemical, and pharmaceutical industries as catalysts in chemical reactions-proves easier than finding the scarce materials themselves.   view more (2007-09-24)

Concentrations of certain toxins in breast milk are low, study finds
Nursing mothers worried about passing harmful chemicals to their infants through breast milk should be aware that the air inside their home may pose a greater health risk.   view more (2007-02-14)

Air pollution affects respiratory health in children with asthma
A new study reports that inner-city children with asthma may be particularly vulnerable to air pollution at levels below current air quality standards.   view more (2008-04-16)

Electronic tongue as oil tester
In the early days of mass motoring, in the 1950s, a car became due for inspection and oil change roughly every 3,000 kilometers. Since then, improvements to car engines and oils have lengthened this interval to around 30,000 kilometers, and it is likely to increase still further: to three times... view more (2003-05-22)

Indoor smoking bans: Are they creating unhealthy outdoor zones for secondhand smoke?
With the growing number of smoking bans in restaurants and bars driving smokers outside, researchers in Athens, Georgia, are hoping to find out whether secondhand smoke from smokers clustered outside these establishments is posing a health hazard of its own.   view more (2007-05-23)

NIST and partners identify tiny gold clusters as top-notch catalysts
For most of us, gold is only valuable if we possess it in large-sized pieces. However, the "bigger is better" rule isn't the case for those interested in exploiting gold's exceptional ability to catalyze a wide variety of chemical reactions, including the oxidation of poisonous carbon... view more (2008-09-08)

Wasabi's kick linked to single pain receptor
A single pain receptor is responsible for the kick delivered by garlic and mustard oil, which is the active ingredient in mustard and in the pungent green sushi condiment known as wasabi, according to a Yale School of Medicine study published this week in Cell.   view more (2006-03-27)
