Major international study warns global warming is destroying coral reefs and calls for 'drastic actions'
If world leaders do not immediately engage in a race against time to save the Earth's coral reefs, these vital ecosystems will not survive the global warming and acidification predicted for later this century. That is the conclusion of a group of marine scientists from around the world in a major... view more (2007-12-26)

Move over, silicon: Advances pave way for powerful carbon-based electronics
Bypassing decades-old conventions in making computer chips, Princeton engineers developed a novel way to replace silicon with carbon on large surfaces, clearing the way for new generations of faster, more powerful cell phones, computers and other electronics.   view more (2007-12-19)

Stanford's nanowire battery holds 10 times the charge of existing ones
Stanford researchers have found a way to use silicon nanowires to reinvent the rechargeable lithium-ion batteries that power laptops, iPods, video cameras, cell phones, and countless other devices.   view more (2007-12-19)

Complex carbon picture clearer
Study shows that more plant litter resulting from higher CO2 could boost the amount of carbon released into the atmosphere.   view more (2007-12-12)

Building blocks of life formed on Mars
Organic compounds contain carbon and hydrogen and form the building blocks of all life on Earth. By analyzing organic material and minerals in the Martian meteorite Allan Hills 84001, scientists at the Carnegie Institution's Geophysical Laboratory have shown for the first time that building blocks... view more (2007-12-12)

New model revises estimates of terrestrial carbon dioxide uptake
Researchers at the University of Illinois have developed a new model of global carbon and nitrogen cycling that will fundamentally transform the understanding of how plants and soils interact with a changing atmosphere and climate.   view more (2007-12-12)

Nitrous oxide from ocean microbes
A large amount of the greenhouse gas nitrous oxide is produced by bacteria in the oxygen poor parts of the ocean using nitrites, Dr Mark Trimmer told journalists at a Science Media Centre press briefing today.   view more (2007-12-11)

Climate gas could disrupt food chain
Levels of a climate cooling gas will change as carbon dioxide increases, affecting food webs along the way, said Dr Michael Steinke at a Science Media Centre press briefing today.   view more (2007-12-11)

Food source threatened by carbon dioxide
Carbon dioxide increasing in the atmosphere may affect the microbial life in the sea, which could have an impact on a major food source, warned Dr Ian Joint at a Science Media Centre press briefing today.   view more (2007-12-11)

Using carbon nanotubes to seek and destroy anthrax toxin and other harmful proteins
Researchers at Rensselaer Polytechnic Institute have developed a new way to seek out specific proteins, including dangerous proteins such as anthrax toxin, and render them harmless using nothing but light.   view more (2007-12-11)

Can Shopping Behavior Indicate Your Personality Type?
The holiday season is the busiest shopping time of the year. In fact, more than 147 million shoppers hit the stores on Black Friday weekend this year according to a survey by the National Retail Federation. And annually during this time, economists pay close attention to the shopping trends.   view more (2007-12-07)

New report on deforestation reveals problems of forest carbon payment schemes
A new study by one of the world's leading forestry research institutes warns that the new push to "reduce emissions from deforestation and degradation," known by the acronym REDD, is imperiled by a routine failure to grasp the root causes of deforestation.   view more (2007-12-07)

Diesel exhaust fumes affect people with asthma, finds study on London's Oxford Street
Diesel exhaust fumes on polluted streets have a measurable effect on people with asthma, according to the first study looking at exhausts and asthma in a real-life setting, published on 6 December in the New England Journal of Medicine.   view more (2007-12-06)

Smell experience during critical period alters brain
Unlike the circuitry of the visual system, that of the olfactory system was thought to be hardwired: Once the neurons had formed, no amount of sensory input could change their arrangement.   view more (2007-12-06)

Iowa State engineer develops laser technologies to analyze combustion, biofuels
Let's say a fuel derived from biomass produces too much soot when it's burned in a combustion chamber designed for fossil fuels. How can an engineer find the source of the problem? It originates, after all, in the flame zone of a highly turbulent combustion chamber. That's not exactly an easy place... view more (2007-12-06)

Can fruit flies help treat stroke and transplant patients?
Reperfusion injury takes place when an animal or an organ is starved of oxygen, then exposed to oxygen again. This occurs in strokes and organ transplants and causes many deaths per year.   view more (2007-12-05)
