Detection of DNA on nanotubes offers new sensing, sequencing technologies
Researchers at the University of Illinois at Urbana-Champaign who recently reported that DNA-wrapped carbon nanotubes could serve as sensors in living cells now say the tiny tubes can be used to target specific DNA sequences.   view more (2006-02-22)

Gulf warm-water eddies intensify hurricane changes
Scientists monitoring ocean heat and circulation in the Gulf of Mexico during Hurricanes Katrina and Rita have a new understanding of how these tropical storms can gain intensity so quickly: The Gulf of Mexico's "Loop Current" is likely intensifying hurricanes that pass over eddies of... view more (2005-10-04)

Journal of the National Cancer Institute
Women with a relatively rare and aggressive form of breast cancer tend to be younger, have larger tumors, and have a poorer survival rate compared with women with the most common forms of the disease, reports a new study in the July 6 issue of the Journal of the National Cancer Institute.   view more (2005-07-06)

Nitrogen pollution boosts plant growth in tropics by 20 percent
A study by UC Irvine ecologists finds that excess nitrogen in tropical forests boosts plant growth by an average of 20 percent, countering the belief that such forests would not respond to nitrogen pollution.   view more (2008-02-07)

When gold becomes a catalyst
Gold has always been perceived as a precious material: you win a gold medal when you prove to be the best in a competition; you only get a Gold credit card when you are a preferential customer, and the jewelry made of this material is amongst the most valuable.   view more (2006-06-23)

UCLA scientists strengthen case for life more than 3.8 billion years ago
Ten years ago, an international team of scientists reported evidence, in a controversial cover story in the journal Nature, that life on Earth began more than 3.8 billion years ago-400 million years earlier than previously thought.   view more (2006-07-24)

Integral looks at Earth to seek source of cosmic radiation
Cosmic space is filled with continuous, diffuse high-energy radiation. To find out how this energy is produced, the scientists behind ESA's Integral gamma-ray observatory have tried an unusual method: observing Earth from space.   view more (2006-03-17)

Ancient greenhouse emissions possible lessons for modern climate
Humans are performing a high-stakes climate experiment by burning fossil fuels that release heat-trapping greenhouse gases into the atmosphere.   view more (2006-02-17)

Gadonanotubes greatly outperform existing MRI contrast agents
Researchers at Rice University, the Baylor College of Medicine, the University of Houston and the Ecole Polytechnique Fédérale de Lausanne in Switzerland have created a new class of magnetic resonance imaging (MRI) contrast agents that are at least 40 times more effective... view more (2005-08-12)

Carbon fiber cars could put U.S. on highway to efficiency
Highways of tomorrow might be filled with lighter, cleaner and more fuel-efficient automobiles made in part from recycled plastics, lignin from wood pulp and cellulose.   view more (2006-03-07)

Heart injury due to carbon monoxide poisoning increases long-term risk of death
Of patients who were hospitalized and treated for moderate to severe carbon monoxide poisoning, those who sustained heart muscle injury due to their exposure had an increased risk of death during a mid-point follow-up period of 7.6 years compared to those without injury to the heart.   view more (2006-01-25)

Storing carbon dioxide below ground may prevent polluting above
A new analysis led by an MIT scientist describes a mechanism for capturing carbon dioxide emissions from a power plant and injecting the gas into the ground, where it would be trapped naturally as tiny bubbles and safely stored in briny porous rock.   view more (2007-02-12)

Cultural approach is key to tackling obesity
Culture plays a significant role in how women perceive obesity in terms of both appearance and health, according to a study by Yale School of Nursing researchers in the Journal of Advanced Nursing.   view more (2006-05-17)

Global atmospheric carbon level may depend primarily on Southern Ocean
Circulation in the waters near the Antarctic coast may be one of the planet's critical means of regulating levels of carbon dioxide in the Earth's atmosphere, according to Princeton researchers.   view more (2006-06-23)

Thawing permafrost a significant source of carbon
Permafrost, permanently frozen soil, isn't staying frozen and a type of soil called loess contained deep within thawing permafrost may be releasing significant, and previously unaccounted for, amounts of carbon into the atmosphere.   view more (2006-06-16)

Soil nutrition affects carbon sequestration in forests
On December 11, USDA Forest Service (FS) scientists from the FS Southern Research Station (SRS) unit in Research Triangle Park, NC, along with colleagues from Duke University, published two papers in The Proceedings of the National Academy of Science (PNAS) that provide a more precise understanding... view more (2006-12-14)

Organic farming produces same corn and soybean yields as conventional farms, but consumes less energy and no pesticides, study finds
Organic farming produces the same yields of corn and soybeans as does conventional farming, but uses 30 percent less energy, less water and no pesticides, a review of a 22-year farming trial study concludes.   view more (2005-07-14)

The first tree genome is published: Poplar holds promise as renewable bioenergy resource
Wood from a common tree may one day factor prominently in meeting transportation fuel needs, according to scientists whose research on the fast-growing poplar tree is featured on the cover of tomorrow's edition of the journal Science.   view more (2006-09-15)

Life and death in the USA: New study concludes there are 'Eight Americas'
Life expectancy in the United States shows some remarkable variations - from place to place, and between races. Researchers have now analysed the figures to conclude that the health of the American people divides them into 'Eight Americas' - based on their race, country of residence, and a few... view more (2006-09-12)

Lucky find off Galapagos
During an expedition off the South American coast, an international team of ocean scientists discovered that the gases ethane and propane are widespread, and are being produced by microorganisms in deeply buried sediments.   view more (2006-09-22)

Albatross study shows regional differences in ocean contamination
As long-lived predators at the top of the marine food chain, albatrosses accumulate toxic contaminants such as PCBs, DDT, and mercury in their bodies. A new study has found dramatic differences in contaminant levels between two closely related albatross species that forage in different areas of the... view more (2006-04-05)

Food-crop yields in future greenhouse-gas conditions lower than expected
Open-air field trials involving five major food crops grown under carbon-dioxide levels projected for the future are harvesting dramatically less bounty than those raised in earlier greenhouse and other enclosed test conditions — and scientists warn that global food supplies could be at risk... view more (2006-06-30)

Why is Greenland covered in ice?
There have been many reports in the media about the effects of global warming on the Greenland ice-sheet, but there is still great uncertainty as to why there is an ice-sheet there at all.   view more (2008-08-28)
