New technique will accelerate genetic characterization of photosynthesis

Tue, 2014-04-15 18:13
Photosynthesis provides fixed carbon and energy for nearly all life on Earth, yet many aspects of this fascinating process remain mysterious. We do not know the full list of the parts of the molecular machines that perform photosynthesis in any organism. A team developed a highly sophisticated tool that will transform the work of plant geneticists on this subject.

Biologists develop nanosensors to visualize movements and distribution of plant stress hormone

Tue, 2014-04-15 13:38
Biologists have succeeded in visualizing the movement within plants of a key hormone responsible for growth and resistance to drought. The achievement will allow researchers to conduct further studies to determine how the hormone helps plants respond to drought and other environmental stresses driven by the continuing increase in the atmosphere’s carbon dioxide, or CO2, concentration.

New design for mobile phone masts could cut carbon emissions

Tue, 2014-04-15 08:44
A breakthrough in the design of signal amplifiers for mobile phone masts could deliver a massive 200MW cut in the load on UK power stations, reducing carbon dioxide emissions by around 0.5 million tons a year.

Political Rifts Slow U.S. Effort on Climate Laws

Tue, 2014-04-15 01:00
Efforts to tackle climate change have repeatedly collided with politics in Washington, where Republicans question the science of global warming, and ties to the fossil fuel industry have made them resistant to change.

Nutrient-rich forests absorb more carbon

Mon, 2014-04-14 10:11
The ability of forests to sequester carbon from the atmosphere depends on nutrients available in the forest soils, shows new research from an international team of researchers. "This paper produces the first evidence that to really understand the carbon cycle, you have to look into issues of nutrient cycling within the soil," said one of the researchers.

U.N. Climate Panel Warns Speedier Action Is Needed to Avert Disaster

Mon, 2014-04-14 01:00
The countries of the world have dragged their feet so long on global warming that the situation is now critical, experts appointed by the United Nations reported Sunday.

Dual role of carbon dioxide in photosynthesis: Pioneering findings

Sun, 2014-04-13 15:40
Carbon dioxide, in its ionic form bicarbonate, has a regulating function in the splitting of water in photosynthesis, researchers have found. This means that carbon dioxide has an additional role to being reduced to sugar. The pioneering work opens up a new research field where researchers can investigate possible biological and ecological consequences of the dual role of carbon dioxide.

Ocean Acidification robs reef fish of their fear of predators

Sun, 2014-04-13 13:59
Research on the behavior of coral reef fish at naturally-occurring carbon dioxide seeps in Milne Bay in eastern Papua New Guinea has shown that continuous exposure to increased levels of carbon dioxide dramatically alters the way fish respond to predators.

Controversy over nitrogen's ocean 'exit strategies' resolved

Fri, 2014-04-11 09:23
A decades-long debate over the dominant way that nitrogen is removed from the ocean may now be settled. Researchers found that both of the nitrogen 'exit strategies,' denitrification and anammox, are at work in the oceans. The debate centers on how nitrogen -- one of the most important food sources for ocean life and a controller of atmospheric carbon dioxide -- becomes converted to a form that can exit the ocean and return to the atmosphere where it is reused in the global nitrogen cycle.

Water: too much, too little

Water: too much, too littleClimate change may accentuate seasonal differences in moisture availabilityClimate change will reduce water availability during dry seasons and increase it during wet seasons around the globe, new research suggests. It also finds there will be large regional variations in water-related impacts. No

April 10, 2014 | Climate change will reduce water availability during dry seasons and increase it during wet seasons around the globe, new research suggests. It also finds there will be large regional variations in water-related impacts. Some areas may see an increase in both droughts and floods by the later part of the 21st century.

Environmental politics: A run for his money

Thu, 2014-04-10 10:59
UK Only Article:  standard article Issue:  Leviathan of last resort Fly Title:  Environmental politics Rubric:  Tom Steyer is betting that campaigning on climate change can win elections. Is the verdant billionaire right? Location:  SAN FRANCISCO Main image:  20140412_USP001_0.jpg DEMOCRATS have often feared big money in American politics, perhaps because most of it doesn’t go their way. When the Supreme Court struck down the caps on aggregate campaign donations last week, Republicans, broadly speaking, cheered and Democrats jeered. In the 2012 election cycle, four of the five biggest donors to superPACs—independent groups that raise money, often from the extremely rich, and spend it on outlandish political advertising—were Republicans. Tom Steyer, a San Francisco-based billionaire who worries about climate change, is doing his best to help his fellow Democrats get over their qualms. Perhaps best known for his opposition to the ...

Making ethanol without corn or other plants

Wed, 2014-04-09 13:47
A copper-based catalyst that produces large quantities of ethanol from carbon monoxide gas at room temperature has been developed by scientists. This promising discovery could provide an eco-friendly alternative to conventional ethanol production from corn and other crops, say the scientists.

Study pegs fuel economy costs of common practices

Wed, 2014-04-09 10:33
People who pack their cars and drive like Clark Griswold in National Lampoon's 'Vacation' pay a steep penalty when it comes to fuel economy. For the study, researchers tested a sport utility vehicle and a compact sedan with various configurations, including underinflated tires, open windows, and rooftop and hitch-mounted cargo. The researchers tested the vehicles at a variety of speeds with the different configurations. While the findings were not unexpected, they serve as a reminder of how drivers can save money by taking simple measures.

Black carbon is ancient by the time it reaches seafloor

Tue, 2014-04-08 11:22
A fraction of the carbon that finds its way into Earth's oceans -- the black soot and charcoal residue of fires -- stays there for thousands for years. A first-of-its-kind analysis shows how some black carbon breaks away and hitches a ride to the ocean floor on passing particles.
