Chemical coffee maker promises purer medicines
Their method uses pressurised carbon dioxide as a solvent, because it allows chemical reactions which usually create a mixture of products to produce only one. Project leaders Chris Rayner and Tony Clifford believe it could change the way pharmaceuticals are manufactured in the future. "If the... view more (1999-03-15)

Deadly gas can protect the heart
Joint release from Northwick Park Institute for Medical Research and the University of Sheffield Scientists have developed a new technology based on carbon monoxide delivery that may protect the heart following a heart attack and prevent rejection of transplanted organs. Researchers from Northwick... view more (2003-08-18)

Corals and Climate Change
A modest new lab at the Rosenstiel School is the first of its kind to tackle the global problem of climate change impacts on corals.   view more (2007-08-23)

The longest carbon nanotubes you've ever seen
Using techniques that could revolutionize manufacturing for certain materials, researchers have grown carbon nanotubes that are the longest in the world. While still slightly less than 2 centimeters long, each nanotube is 900,000 times longer than its diameter.   view more (2007-05-11)

Nanoparticles assemble by millions to encase oil drops
In a development that could lead to new technologies for cleaning up oil spills and polluted groundwater, scientists at Rice University have shown how tiny, stick-shaped particles of metal and carbon can trap oil droplets in water by spontaneously assembling into bag-like sacs.   view more (2008-05-30)

Soviet plans implemented by Nature 90,000 years ago
One of the more controversial environmental issues, which emerged in the final years of the Soviet era, was the plan to dam and reverse the flow of north-flowing rivers in order to irrigate the dry southern steppes. This scheme was roundly criticised by scientists and environmentalists at the time... view more (2002-01-22)

When preventing pre-eclampsia, a little carbon monoxide goes a long way
Researchers have shown that carbon monoxide may prevent the placental cell death caused by oxidative stress injury, possibly averting the risks of pre-eclampsia.   view more (2006-09-05)

NASA's Chandra Finds Evidence for Quasar Ignition
New data from NASA's Chandra X-ray Observatory may provide clues to how quasars "turn on."   view more (2006-03-24)

Blowing away ethnic stereotyping in tests
It is often thought that Asian cultures value accuracy over speed of performance and Black groups are less concerned with accuracy than White groups. Contrary to popular belief research shows these stereotypes do not exist in psychometric testing.   view more (2005-01-07)

Galaxy Cluster Takes It to the Extreme
Evidence for an awesome upheaval in a massive galaxy cluster was discovered in an image made by NASA's Chandra X-ray Observatory. The origin of a bright arc of ferociously hot gas extending over two million light years requires one of the most energetic events ever detected.   view more (2007-05-31)

Scientists expand understanding of how river carbon impacts the Arctic Ocean
Arctic rivers transport huge quantities of dissolved organic carbon (DOC) to the Arctic Ocean. The prevailing paradigm regarding DOC in arctic rivers is that it is largely refractory, making it of little significance for the biogeochemistry of the Arctic Ocean.   view more (2008-02-13)

Experiment suggests limitations to carbon dioxide 'tree banking'
While 10 years of bathing North Carolina pine tree stands with extra carbon dioxide did allow the trees to grow more tissue, only those pines receiving the most water and nutrients were able to store significant amounts of carbon that could offset the effects of global warming, scientists told a... view more (2007-08-07)

Scientists predict how to detect a fourth dimension of space
Scientists at Duke and Rutgers universities have developed a mathematical framework they say will enable astronomers to test a new five-dimensional theory of gravity that competes with Einstein's General Theory of Relativity.   view more (2006-05-26)

Tropical rainforest nutrients linked to global carbon dioxide levels
Extra amounts of key nutrients in tropical rain forest soils cause them to release more carbon dioxide into the atmosphere, according to research conducted by scientists at the University of Colorado (CU)—Boulder.   view more (2006-06-21)

NIST develops rapid method for judging nanotube purity
Researchers at the National Institute of Standards and Technology (NIST) have developed a sensitive new method for rapidly assessing the quality of carbon nanotubes.   view more (2007-02-02)

Warming could free far more carbon from high Arctic soil than earlier thought
Scientists studying the effects of carbon on climate warming are very likely underestimating, by a vast amount, how much soil carbon is available in the high Arctic to be released into the atmosphere, new University of Washington research shows.   view more (2005-12-06)

White Christmases unlikely
CRed, the community carbon reduction project run out of the University of East Anglia, is urging people to aim for a low carbon Christmas this year. CRed say that the reason we no longer have any White Christmases is down to global warming and that we need to work harder at reducing our carbon... view more (2003-12-03)

Race may be risk factor for insulin resistance
Black women — even if their weight is normal — may be at increased risk for insulin resistance, a condition associated with diabetes, high blood pressure, and heart vessel disease, according to new research by Wake Forest University School of Medicine.   view more (2006-06-27)

Woods Hole Research Center scientist furthering discussion of soil carbon decomposition
Significantly more carbon is stored in the world's soils than is present in the atmosphere. In a process called a "positive feedback," global warming may stimulate decomposition of soil organic matter, thus releasing heat-trapping carbon dioxide gas to the atmosphere, possibly causing the... view more (2006-03-09)

Spin control: New technique sorts nanotubes by length
Researchers at the National Institute of Standards and Technology (NIST) have reported a new technique to sort batches of carbon nanotubes by length using high-speed centrifuges.   view more (2008-05-19)

UniS' nanotechnology expertise on show at Science Museum
The University of Surrey's world-class expertise in nanotechnology research is a key contributor to a new exhibition entitled 'Nanotechnology: small science‚ big deal', now showing at the Science Museum in London. Professor Ravi Silva, from the University's Advanced Technology Institute... view more (2005-03-09)

Dust threatens Kyoto protocol
On the eve of the Earth Summit in Johannesburg, scientists at UCL have detected a flaw in the Kyoto protocol`s global plans to reduce the impact of global warming, all because of something as simple as atmospheric dust. Dr Mark Maslin of UCL`s Environmental Change Research Centre explains: "Dust is... view more (2002-08-07)

Forests' long-term potential for carbon offsetting
As well as cutting our fossil fuel emissions, planting new forests, or managing existing forests or agricultural land more effectively can capitalise on nature's ability to act as a carbon sink.   view more (2008-04-15)

Using an activated-carbon filtering pitcher significantly reduces chemicals in tap water
A study conducted by Université Laval researchers concludes that using an activated-carbon filtering pitcher is the most effective way to reduce disinfection by-products in tap water.   view more (2006-11-03)

Rising surface ozone reduces plant growth and adds to global warming
Scientists from three leading UK research institutes have today released new findings that could have major implications for food production and global warming in the 21st century.   view more (2007-07-26)
