Greenhouse gases are the most imminently threatening weapons of mass destruction
Global warming poses an increasingly sizeable threat to the continued existence of man. James Lovelock, atmospheric chemist and author of Gaia warns that the gravity of the situation facing Earth's inhabitants is greater than we have yet realized and accepted. Lovelock sets forth his predictions -- and proposed solutions -- in a commentary piece... view more... (2004-10-18)
Meeting the challenges of providing clean energy: Commission looks into clean alternatives to fossil fuels
Photovoltaics is a science that examines light-electricity conversion. Conversion of solar energy carried by photons is transformed by solar cells into direct-current electrical energy. Interest in the use of photovoltaic (PV) solar technologies is growing rapidly, as it will permit the direct production of electricity from solar radiation without... view more... (2002-06-06)
Should we implement the Kyoto protocol? Spiked and Natural Environment Research Council launch debate on global warming.
On Tuesday 20 November, the online publication spiked and the Natural Environment Research Council (NERC) are launching a debate on global warming. To initiate the debate, Professor Bj'¸rn Lomborg, author of the controversial book The Skeptical Environmentalist, will put the case against implementing the Kyoto protocol. Dr Mike Hulme, executive... view more... (2001-11-13)
Algae could one day be major hydrogen fuel source
As gas prices continue to soar to record highs, motorists are crying out for an alternative that won't cramp their pocketbooks. view more (2008-04-02)
Mandate for biofuels production requires science-based policy and global perspective
In his State of the Union Address on January 23, 2007, President Bush stated that, in order to substantially lower foreign oil imports, "We must increase the supply of alternative fuels, by setting a mandatory fuels standard to require 35 billion gallons of renewable and alternative fuels in 2017." view more (2008-10-03)
Sunlight turns carbon dioxide to methane
Dual catalysts may be the key to efficiently turning carbon dioxide and water vapor into methane and other hydrocarbons using titania nanotubes and solar power, according to Penn State researchers. view more (2009-03-05)
Deep-sea oil rigs inspire MIT designs for giant wind turbines
An MIT researcher has a vision: Four hundred huge offshore wind turbines are providing onshore customers with enough electricity to power several hundred thousand homes, and nobody standing onshore can see them. view more (2006-09-19)
York-Sichuan link to study biodiesel production
Biologists at the University of York have established new research links with Chinese scientists to investigate biodiesel - a cleaner, more environmentally friendly alternative to petroleum. view more (2007-01-05)
UniS Professor appointed to advise government Select Committee on energy efficiency
Professor Roland Clift, Director of the Centre for Environmental Strategy at the University of Surrey, has been appointed a Specialist Adviser to a sub-committee conducting an inquiry into the Government's policies on energy efficiency. view more (2004-09-29)
Sandia-developed device determines how well wind turbines operate
In West Texas, New Mexico, and other places around the world, wind turbines are used to generate electricity. But how can engineers determine their efficiency and health? view more (2006-07-27)
Mixed prairie grasses are better biofuel source, U of M study says
Highly diverse mixtures of native prairie plant species have emerged as a leader in the quest to identify the best source of biomass for producing sustainable, bio-based fuel to replace petroleum. view more (2006-12-08)
Corn waste potentially more than ethanol
After the corn harvest, whether for cattle feed or corn on the cob, farmers usually leave the stalks and stems in the field, but now, a team of Penn State researchers think corn stover can be used not only to manufacture ethanol, but to generate electricity directly. view more (2006-07-20)
The secret to long life
What controls lifespan? An intriguing new twist is emerging from the work of Professor Heinz Osiewacz (Frankfurt) using a short-lived fungus. He has discovered that when there is a mutation in the gene, Grisea, that controls copper uptake into cells, the fungus can live 60% longer than their normal wild-types. Why is this? Professor Osiewacz... view more... (2001-04-04)
ORNL helps develop next-generation LEDs
Nanotechnology may unlock the secret for creating highly efficient next-generation LED lighting systems, and exploring its potential is the aim of several projects centered at Oak Ridge National Laboratory. view more (2007-03-20)
Microbes turn electricity directly to methane without hydrogen generation
A tiny microbe can take electricity and directly convert carbon dioxide and water to methane, producing a portable energy source with a potentially neutral carbon footprint, according to a team of Penn State engineers. view more (2009-03-31)
Planet-sized solutions for global warming: International experts evaluate the options
Big ideas for reducing the impacts of climate change are being evaluated by an international line-up of leading scientists from the US, mainland Europe and the UK at a symposium in Cambridge this week. The scientists are coming together to evaluate which large-scale bio-engineering, geo-engineering and chemical engineering ideas to combat global... view more... (2004-01-05)
Mammalian neurogenesis breaks into the most static brain region
ifteen years ago, the discovery of adult neurogenesis (the production of new neurons) in the highly static, non-renewable mammalian brain was a breakthrough in neuroscience. view more (2008-06-04)
Bringing solar power to the masses
On a 104-degree Friday in July when sunlight bathed The University of Arizona campus, doctoral student Dio Placencia sat before a noisy vacuum chamber in the Chemical Sciences Building trying to advance the renewable energy revolution. view more (2009-08-06)
Experiments at UCSB push quantum mechanics to higher levels
Scientists at UC Santa Barbara have devised a new type of superconducting circuit that behaves quantum mechanically -- but has up to five levels of energy instead of the usual two. The findings are published in the August 7 issue of Science. view more (2009-08-12)
The fight against obesity -- a new insight
With obesity still on the increase, it appears that the main weapon in the fight against it - reducing energy consumption by eating less - is ineffective. view more (2008-03-12)
