Engineered eggshells to help make hydrogen fuel
Engineers at Ohio State University have found a way to turn discarded chicken eggshells into an alternative energy resource. The patented process uses eggshells to soak up carbon dioxide from a reaction that produces hydrogen fuel. It also includes a unique method for peeling the... view more (2007-09-27)

New isotope molecule may add to Venus' greenhouse effect
Planetary scientists on both sides of the Atlantic have tracked down a rare molecule in the atmospheres of both Mars and Venus. The molecule, an exotic form of carbon dioxide, could affect the way the greenhouse mechanism works on Venus.   view more (2007-10-11)

Controlling the Size of Nanoclusters: First Step in Making New Catalysts
Researchers from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Stony Brook University have developed a new instrument that allows them to control the size of nanoclusters - groups of 10 to 100 atoms - with atomic precision.   view more (2008-07-10)

Oceans may soon be more corrosive than when the dinosaurs died
Increased carbon dioxide emissions are rapidly making the world's oceans more acidic and, if unabated, could cause a mass extinction of marine life similar to one that occurred 65 million years ago when the dinosaurs disappeared.   view more (2006-02-21)

New membrane strips carbon dioxide from natural gas faster and better
A modified plastic material greatly improves the ability to separate global warming-linked carbon dioxide from natural gas as the gas is prepared for use, according to engineers at The University of Texas at Austin who have analyzed the new plastic's performance.   view more (2007-10-12)

Dinosaur Deaths Outsourced to India?
A series of monumental volcanic eruptions in India may have killed the dinosaurs 65 million years ago, not a meteor impact in the Gulf of Mexico.   view more (2007-10-31)

Brightening up old church windows
Somber semi-darkness, flickering candles and the smell of incense - visitors to old churches are delighted by this atmosphere, especially at Christmas time. Yet only a few of them will have noticed that Gothic churches are growing darker inside with every passing year. The reason: Deposits of soot... view more (2002-12-20)

Virginia Tech researcher reports nano-particle dispersion technique improves polymers
There is a lot of excitement about incorporating nano particles into polymers because of the ability to improve various properties with only a small percent of the particles.   view more (2005-08-30)

Study outlines eruption at undersea volcano
An international team of scientists has presented its findings from the first observations of the eruption of a submarine volcano that in 2004 and 2005 spewed out plumes of sulfur-rich fluid and pulses of volcanic ash 550 meters below the ocean's surface near the Mariana Islands northwest of Guam.   view more (2006-05-25)

Plymouth Leads 'healthy Oceans' Research
Plymouth researchers will be presenting new research findings at an international conference they are hosting in the city next month. Professor Paul Worsfold, Co-director of Plymouth Environmental Research Centre (PERC), heads the Plymouth team working on a three-year research project which... view more (2002-05-28)

New Type Of Reactor Developed For Cleaner, Safer Chemical Processing
Scientists in the UK are using an unusual form carbon dioxide in a new type of reactor capable of carrying out commercially important chemical processes which could be cheaper, safer and cleaner than their conventional counterparts. The work, reported in this month’s EPSRC Newsline is being... view more (2001-02-05)

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)

Arctic soil reveals climate change clues
Frozen arctic soil contains nearly twice the greenhouse-gas-producing organic material as was previously estimated, according to recently published research by University of Alaska Fairbanks scientists.   view more (2008-10-08)

New knowledge about plutonium calms scientists
New analyses from KTH in Stockholm are creating order in the uncertainty that has prevailed for the last four years about how plutonium dioxide, one of the most important radioactive compounds in nuclear waste, behaves when it comes into contact with water. The findings are being published in the... view more (2004-03-19)

Mileage from megawatts: Study finds enough electric capacity to "fill up" plug-in vehicles across much of the nation
If all the cars and light trucks in the nation switched from oil to electrons, idle capacity in the existing electric power system could generate most of the electricity consumed by plug-in hybrid electric vehicles.   view more (2006-12-12)

CNRS makes undersea window-cleaners redundant
The formation of bio-films is a major problem for undersea optical instruments. To prevent fouling, researchers at the Electro-Chemical Systems and Interfaces Laboratory (LISE) at CNRS (France's leading research establishment) have contributed to the development of a very promising electro-chemical... view more (2004-03-05)

Banana Boat to Help with Climate Research
A refrigerated cargo vessel in the banana trade is set to contribute to research about climate change, in a new collaboration between the University of East Anglia (UEA) and The Geest Line, a commercial shipping line based in Southampton. As part of a unique Europe-wide project, a commercial... view more (2001-12-05)

Dental chair a possible source of neurotoxic mercury waste
Mercury is a large component of dental fillings, but it is not believed to pose immediate health risks in that form. When exposed to sulfate-reducing bacteria, however, mercury undergoes a chemical change and becomes methylated, making it a potent, ingestible neurotoxin.   view more (2008-03-27)

Separating uranium from plutonium
Moscow researchers have made the supercritical carbon dioxide work. Saturated with special reagents, carbon dioxide first extracts uranium from the spent nuclear fuel waste, then extracts plutonium and then flies away into the atmosphere. As a matter of fact, the spent nuclear fuel consists of... view more (2003-08-08)

Rare high-altitude clouds found on Mars
Planetary scientists have discovered the highest clouds above any planetary surface. They found them above Mars using the SPICAM instrument on board ESA's Mars Express spacecraft. The results are a new piece in the puzzle of how the Martian atmosphere works.   view more (2006-08-29)

Wildfires Cause Ozone Pollution to Violate Health Standards, New Study Shows
Wildfires can boost ozone pollution to levels that violate U.S. health standards, a new study concludes.   view more (2008-10-10)

Carbon dioxide triggers inborn distress
PLoS ONE publishes a study showing that inhalation of carbon dioxide (CO2) triggers emotional distress and a panic response in healthy individuals. The findings of the study posit panic as an inborn survival-oriented response. The results may be relevant for a better understanding and the further... view more (2007-10-03)

Old growth forests are valuable carbon sinks
Contrary to 40 years of conventional wisdom, a new analysis to be published Friday in the journal Nature suggests that old growth forests are usually "carbon sinks" - they continue to absorb carbon dioxide from the atmosphere and mitigate climate change for centuries.   view more (2008-09-11)

Canada's new government invests in carbon capture research delivering real results on greenhouse gas
The Honourable Gary Lunn, Minister of Natural Resources, along with partners from Innoventures Canada (I-CAN), today announced funding for a project related to the initial development of the I-CAN Centre for the Conversion of Carbon Dioxide (CO2), at the Economic Club in Calgary.   view more (2007-03-13)

Northern forests less effective than tropical forests in reducing global warming
