Tiny Tubes and Rods Show Promise as Catalysts, Sunscreen
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed new ways to make or modify nanorods and nanotubes of titanium oxide, a material used in a variety of industrial and medical applications. view more (2007-09-11)
Emissions irrelevant to future climate change?
Climate change and the carbon emissions seem inextricably linked. However, new research published in BioMed Central's open access journal Carbon Balance and Management suggests that this may not always hold true, although it may be some time before we reach this saturation point. view more (2008-04-28)
Role of Silica in Climate Cycles
New research from the University of East Anglia (UEA) has demonstrated that the compound silica was not solely responsible for changes in carbon dioxide levels during past Ice Ages. It is already known from scientific research that during past Ice Ages increased amounts of silica, a common component of wind-blown dust, were deposited in the ocean.... view more... (2001-06-21)
Rivers are carbon processors, not inert pipelines
Microorganisms in rivers and streams play a crucial role in the global carbon cycle that has not previously been considered. view more (2008-12-02)
Pitt researchers harness carbon nanomaterials for drug delivery systems, oxygen sensors
Two nanoscale devices recently reported by University of Pittsburgh researchers in two separate journals harness the potential of carbon nanomaterials to enhance technologies for drug or imaging agent delivery and energy storage systems, in one case, and, in the other, bolster the sensitivity of oxygen sensors essential in confined settings, from... view more...

Carbon offset warning from international team of scientists
Leading marine scientists from across the world have issued a warning that it is too early to sell carbon offsets from ocean iron fertilisation. view more (2008-01-11)
Seeing the forest and the trees helps cut atmospheric carbon dioxide
Putting a price tag on carbon dioxide emitted by different land use practices could dramatically change the way that land is used - forests become increasingly valuable for storing carbon and overall carbon emissions reductions become cheaper, according to research presented today at the annual meeting of the American Association for the... view more...

UA scientists part of Supreme Court case on carbon dioxide emissions
Four faculty members from The University of Arizona in Tucson were part of an amicus curiae brief supporting the plaintiff in today's historic U.S. Supreme Court decision on carbon dioxide emissions and climate change. view more (2007-04-03)
New isotope cluster could lead to better understanding of atmospheric carbon dioxide
A team of researchers has discovered an unexpected concentration of a certain isotopic molecule in parts of the stratosphere that could have implications for understanding the carbon cycle and its response to climate change. view more (2009-07-15)
Carbon turns over much faster through basal food-chain levels in aquatic than in terrestrial ecosystems
Global temperatures have increased dramatically over the past century, which is causing major impacts on climate patterns, ocean circulation and wildlife preservation. The increase in temperature is largely due to a rise of anthropogenic emissions of greenhouse gases, of which CO2 is one of the most important. To understand the capacity of... view more...

Before selling carbon credits, read this
Storing carbon in agricultural soils presents an immediate option to reduce atmospheric carbon dioxide and slow global warming. view more (2007-05-21)
Go Speed Racer! Revving up the world's fastest nanomotors
In a "major step" toward a practical energy source for powering tomorrow's nanomachines, researchers in Arizona report development of a new generation of sub-microscopic nanomotors that are up to 10 times more powerful than existing motors. Their study is scheduled for the May 27 issue of ACS Nano, a monthly journal. view more (2008-05-01)
New Business/Academic Partnership delivers £14 M for low carbon innovation
(Press Release issued by Carbon Trust and EPSRC) Today (11 November), Carbon Trust and the Engineering and Physical Sciences Research Council (EPSRC) announces the launch of a new £14 million investment initiative which will marry the needs of business with the capabilities of University R&D departments to deliver on low carbon... view more...

Rise in atmospheric CO2 accelerates as economy grows, natural carbon sinks weaken
Human activities are releasing carbon dioxide faster than ever, while the natural processes that normally slow its build up in the atmosphere appear to be weakening. view more (2007-10-23)
Tough new probe developed for nanotechnologists
Since the invention of the atomic force microscope (AFM) in 1986 by Nobel laureate Gerd Binnig, the tool has been employed to advance the science of materials in many ways, from nanopatterning (dip-pen nanolithography) to the imaging of surfaces and nano-objects such as carbon nanotubes, DNA, proteins and cells. In all these applications, the... view more... (2005-08-11)
Global climate change: a load of poo?
Plankton poo could be the key to understanding how much carbon dioxide our oceans can store according to Tasmanian researcher Dr Karin Beaumont. view more (2004-09-09)
Test finds manufactured nanoparticles don't harm soil ecology
The first published study on the environmental impact of manufactured nanoparticles on ordinary soil showed no negative effects, which is contrary to concerns voiced by some that the microscopic particles could be harmful to organisms. view more (2007-03-23)
Beneficial effects of no-till farming depend upon future climate change
By storing carbon in their fields through no-till farming practice, farmers can help countries meet targeted reductions in atmospheric carbon dioxide and reduce the harmful effects of global warming. view more (2005-10-13)
TREATING POLLUTED LAND WITH CARBON DIOXIDE
First a granular binder containing products which react with carbon is added to the contaminated soil and then carbon dioxide is pumped into the mixture. The three components rapidly combine to produce a cement that is very stable, and although marginally more expensive is immediately available for development. The land can then be used for... view more... (1999-11-25)
Climate change will affect carbon sequestration in oceans, model shows
The direct injection of carbon dioxide deep into the ocean has been suggested as one method to help control rising carbon dioxide levels in the atmosphere and mitigate the effects of global warming. view more (2005-09-08)
