Powerful new tool to track carbon dioxide by source
Scientists from NOAA's Earth System Research Laboratory released today a powerful new tool to monitor changes in atmospheric carbon dioxide and other greenhouse gases by region and source around the world. Called CarbonTracker, the online system will distinguish between changes in the natural carbon cycle and those occurring in fossil fuel... view more... (2007-03-22)
Future for clean energy lies in 'big bang' of evolution
Amid mounting agreement that future clean, "carbon-neutral", energy will rely on efficient conversion of the sun's light energy into fuels and electric power, attention is focusing on one of the most ancient groups of organism, the cyanobacteria. view more (2008-08-25)
Morphology of fossil salamanders reflects climate change
A fossil record of the Tiger Salamander (Ambystoma tigrinum) shows population-wide changes in body size and morphology in response to climate change over the last 3,000 years. view more (2005-09-13)
Simple device which uses electrical field could boost gas efficiency
With the high cost of gasoline and diesel fuel impacting costs for automobiles, trucks, buses and the overall economy, a Temple University physics professor has developed a simple device which could dramatically improve fuel efficiency as much as 20 percent. view more (2008-09-26)
Hydrogen storage can be improved
The storage of hydrogen in fuel cell powered cars can probably be greatly improved by increasing the working temperature of the fuel cell. With the use of magnesium powder, the storage of hydrogen can take place more efficiently and safely and at a higher temperature. This is the conclusion of Gijs Schimmel, who will defend his PhD thesis at TU... view more... (2005-01-26)
Fuel cells, a neglected clean source of energy
In a situation where the UK is crying out for reliable sources of energy that do not threaten the environment, one option, the hydrogen fuel cell has been relatively neglected through insufficient support from industry and government. view more (2006-07-24)
Findings could improve fuel cell efficiency
A new type of membrane based on tiny iron particles appears to address one of the major limitations exhibited by current power-generating fuel cell technology. view more (2008-03-20)
Earth's first rainforest unearthed
A spectacular fossilised forest has transformed our understanding of the ecology of the Earth's first rainforests. It is 300 million years old. view more (2007-04-23)
Good times ahead for dinosaur hunters, according to U of Penn scientist's dinosaur census
The golden age of dinosaur discovery is yet upon us, according to Peter Dodson at the University of Pennsylvania. view more (2006-09-05)
U. of Colorado study shows massive CO2 burps from ocean to atmosphere at end of last ice age
A University of Colorado at Boulder-led research team tracing the origin of a large carbon dioxide increase in Earth's atmosphere at the end of the last ice age has detected two ancient "burps" that originated from the deepest parts of the oceans. view more (2007-05-11)
Shifting the world to 100 percent clean, renewable energy as early as 2030 -- here are the numbers
Most of the technology needed to shift the world from fossil fuel to clean, renewable energy already exists. Implementing that technology requires overcoming obstacles in planning and politics, but doing so could result in a 30 percent decrease in global power demand. view more (2009-10-20)
Was ability to run early man's Achilles heel?
The earliest humans almost certainly walked upright on two legs but may have struggled to run at even half the speed of modern man, new research suggests. view more (2007-09-11)
Delaware State U. scientists refine hydrogen fuel-cell vehicle power plants
Hydrogen fuel-cell vehicles (FCVs) can be an important part of the solution to America's energy crisis, says Dr. Andrew Goudy of Delaware State University. He is leading a research team striving to solve a key technical FCV puzzle. view more (2009-07-27)
Ethiopia 27 million years ago had higher rainfall, warmer soil
Thirty million years ago, before Ethiopia's mountainous highlands split and the Great Rift Valley formed, the tropical zone had warmer soil temperatures, higher rainfall and different atmospheric circulation patterns than it does today, according to new research of fossil soils found in the central African nation. view more (2009-10-23)
Wenchuan earthquake mudslides emit greenhouse gas
Mudslides that followed the 12 May 2008 Wenchuan, China earthquake, ranked by the US Geological Survey as the 11th deadliest earthquake ever recorded, may cause a carbon-dioxide release in upcoming decades equivalent to two percent of current annual global carbon emissions from fossil fuel combustion, a new study shows. view more (2009-03-03)
Microbes fuel energy debate
Microbes may well be the answer to our global energy crisis. By fermenting biomass to produce biofuels, they offer a possible climate-friendly solution to the anticipated shortfall in fossil fuel supply. view more (2009-01-23)
New fuel consumption-cutting product to be trialled by Stagecoach
Cerulean International Limited, the Oxford, UK-based subsidiary of the British nanomaterials company Oxonica Limited, has announced that its new product Envirox is to be commercially evaluated by Stagecoach UK, with a view to adopting the product over Stagecoach's 7000 strong UK bus fleet. Using new technology, Cerulean has developed Envirox, a... view more... (2003-10-15)
Major progress in technology needed for 25 percent renewable energy use to be affordable
Dramatic progress in renewable energy technology is needed if the United States desires to produce 25 percent of its electricity and motor vehicle fuel from renewable sources by 2025 without significantly increasing consumer costs. view more (2008-06-25)
Warplane system could cut mid-air explosion
AIRLINES are facing fresh calls for their aircraft`s fuel tanks to be fitted with explosion-prevention systems like those on military planes. This follows a warning from Boeing that 3200 of its planes may have faulty fuel pumps that could spark explosions. Boeing says a spark from wiring in the pumps could ignite vapour in a near-empty tank. The... view more... (2002-10-02)
Purdue engineers create safer, more efficient nuclear fuel, model its performance
Purdue University nuclear engineers have developed an advanced nuclear fuel that could save millions of dollars annually by lasting longer and burning more efficiently than conventional fuels, and researchers also have created a mathematical model to further develop the technology. view more (2005-09-29)
