Hybrid electric vehicles that run on both conventional gasoline and stored electricity can be no more than a stop gap until more sustainable technology is developed, according to researchers in France.   view more (2008-02-07)

Scientists using laser light to detect potential diseases via breath samples, says new study
By blasting a person's breath with laser light, scientists from the National Institute of Standards and Technology and the University of Colorado at Boulder have shown that they can detect molecules that may be markers for diseases like asthma or cancer.   view more (2008-02-19)

A way to convert natural gas into raw materials for the chemical industry and generate power as a by-product could lead to more environmental benign manufacturing processes.   view more (2007-09-12)

New mammography technology effective in detecting breast cancer
A study has found that positron emission mammography (PEM), a new technique for imaging the breast, is not affected by either breast density or a woman's hormonal status, two factors that limit the effectiveness of standard mammography and MRI at detecting cancer.   view more (2008-12-02)

Turning Waste Material into Ethanol
Say the word "biofuels" and most people think of grain ethanol and biodiesel. But there's another, older technology called gasification that's getting a new look from researchers at the U.S. Department of Energy's Ames Laboratory and Iowa State University. By combining gasification with... view more (2008-08-14)

Sardines May Prevent Toxic Gas Eruptions off the California and African Coasts
Milky, turquoise-colored "dead zones," some as large as the U.S. State of New Jersey, that are appearing repeatedly off the coast of southwest Africa, may be a sign of things to come for other areas of the coastlines of the eastern Atlantic and Pacific oceans. Toxic gas eruptions,... view more (2005-01-11)

Ultraviolet radiation induced flux of nitrogen oxides from pine needles
In the latest edition of Nature (March 13th, 2003) a group of scientist led by professor Pertti Hari from the University of Helsinki presents a novel observation: ultraviolet radiation induced a flux of nitrogen oxides (NOx) from pine needles to the atmosphere. This result is interesting because... view more (2003-03-14)

Research finds that Earth's climate is approaching 'dangerous' point
NASA and Columbia University Earth Institute research finds that human-made greenhouse gases have brought the Earth's climate close to critical tipping points, with potentially dangerous consequences for the planet.   view more (2007-06-01)

Magnetism shapes beauty in the heavens
Using a technique based on the work of the 1902 Nobel Prizewinner, Pieter Zeeman, an international team of astronomers have, for the first time, provided conclusive proof that the magnetic field close to a number of aging stars is 10 to 100 times stronger than that of our own Sun. These... view more (2002-11-01)

The accretion disks around super-massive black holes: do they really exist?
Active Galactic Nuclei (AGN) and quasars (QSO) are the most luminous objects in the sky. These are powered by accretion of interstellar gas onto a supermassive black hole (BH) of about 100 millions solar masses which stands at the center of galaxies. For Seyfert galaxies, a few tenths of solar... view more (2001-04-17)

Chemical Industry Gives Mixed Response to Greenhouse Gas Emissions Trading Scheme
The Chemical Industries Association (CIA) today expressed concern that the UK's allocation of greenhouse gas emissions is still not finally decided, but applauded the UK Government's decision to press the European Commission for approval of the revised limits.   view more (2005-02-15)

Multi-wavelength images help astronomers study star birth, death
In recent years, a number of ground-based optical and radio surveys of the Large and Small Magellanic Clouds - Earth's nearest neighboring galaxies - have become available.   view more (2006-01-12)

Boiler modifications cut mercury emissions 70 percent or more, research team finds
Researchers at Lehigh University's Energy Research Center (ERC) have developed and successfully tested a cost-effective technique for reducing mercury emissions from coal-fired power plants.   view more (2005-10-04)

Diamonds key to a sparkling listening experience
Music lovers could be in for the ultimate listening experience, thanks to a new range of speakers containing parts made of diamond, writes Marina Murphy in the Chemistry & Industry magazine. The unique properties of diamond make the speakers less susceptible to distortion and thus provide a... view more (2005-02-18)

Laser light may be able to detect diseases on the breath
A team of scientists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado (CU) at Boulder, has shown that by sampling a person's breath with laser light they can detect molecules in the breath that may be markers for diseases like... view more (2008-02-19)

Air Quality Forecasts for China
With less than a month remaining before the Beijing Olympics, Chinese officials have introduced a series of measures to improve air quality for the Games. A new tool has been installed in the capital city to allow the Chinese to monitor the effectiveness of these efforts.   view more (2008-07-24)

UK researchers announce continuous Terahertz emission innovation
Researchers at the University of Leeds' Institute of Microwaves and Photonics have developed a novel way of generating continuous tunable Terahertz (THz) radiation.   view more (2002-11-14)

Preventing obesity in children — research highlights physical activity levels
A British study, involving 5,500 children and published in the latest issue of PLoS Medicine, used accurate methods to measure the 'fat mass' of the children and the amount of physical activity they were taking.   view more (2007-03-20)

Pioneering system for the compression of additives in food conservation
Researchers at the Public University of Navarre, the University of La Rioja and the enterprise Diasa Industrial are designing a machine which makes food additives in pellet form with substances that have been hitherto impossible to compress. The idea is to develop an existing project for a new... view more (2003-07-08)

Frozen sea discovered near Martian equator from 3D images of Mars Express
The discovery, by an international team of scientists led by University College London (UCL), the Open University (OU), and the Free University of Berlin, of a frozen sea close to the equator of Mars has brought the possibility of finding life on Mars one step closer. This is the first evidence of... view more (2005-02-22)

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... view more (2006-06-22)

CSI: Milky Way team works scene of dead star
Like a team of forensic detectives in a television show that could be called "CSI: Milky Way," a University of Chicago astrophysicist and his associates are piecing together how a mysterious infrared ring got left around a dead star that displays a magnetic field trillions of times more... view more (2008-05-29)

New robot scouts best locations for components of undersea lab
Like a deep-sea bloodhound, Sentry - the newest in an elite group of unmanned submersibles able to operate on their own in demanding and rugged environments - has helped scientists pinpoint optimal locations for two observation sites of a pioneering seafloor laboratory being planned off Washington... view more (2008-08-14)

Pitt professor designs less-risky reactor for clean, safe energy
Reactors that burn hydrogen or natural gas to generate energy can be dirty and dangerous. The mix of air with hydrogen or natural gas can explode easily if composition and temperature are not carefully controlled. And reactors often produce polluting byproducts.   view more (2006-09-13)

Europe to tackle brain disorder research by linking industry, academia
