 Big data project reveals where carbon-stocking projects in Africa provide the greatest benefits Aarhus, Denmark (SPX) Dec 23, 2013 - It is increasingly recognized that climate change has the potential to threaten people and nature, and that it is imperative to tackle the drivers of climate change, namely greenhouse gases. One way to slow climate change is to increase the number of trees on Earth, as they, through photosynthesis, take up the greenhouse gas carbon dioxide, converting it to carbon products which are stored in th ... more |  |
 Enormous Aquifer Discovered Under Greenland Ice Sheet Greenbelt MD (SPX) Dec 24, 2013 - Buried underneath compacted snow and ice in Greenland lies a large liquid water reservoir that has now been mapped by researchers using data from NASA's Operation IceBridge airborne campaign. A team of glaciologists serendipitously found the aquifer while drilling in southeast Greenland in 2011 to study snow accumulation. Two of their ice cores were dripping water when the scientists lifte ... more |  |
Electric-Blue Clouds Appear over Antarctica Huntsville AL (SPX) Dec 24, 2013 - Data from NASA's AIM spacecraft show that noctilucent clouds are like a great "geophysical light bulb." They turn on every year in late spring, reaching almost full intensity over a period of no more than 5 to 10 days. News flash: The bulb is glowing. As December unfolds, a vast bank of noctilucent clouds is blanketing Antarctica. It started on Nov. 20th as a tiny puff of electric-blue an ... more |  |
 Virginia Tech research overturns assumption about mercury in the Arctic Blacksburg VA (SPX) Dec 23, 2013 - For years, scientists have assumed that if mercury is high and increasing in fish in the North American and European Arctic, the same is true of fish elsewhere in the Arctic. But a team of scientists from the U.S., Russia, and Canada has discovered that assumption is wrong in much of the continental Arctic. In addition to differences in mercury processes as a result of diverse atmosp ... more |  |
 Malaria drug target raises hopes for new treatments London UK (SPX) Dec 23, 2013 - Scientists have taken an important step towards new malaria treatments by identifying a way to stop malaria parasites from multiplying. In a study published in Nature Chemistry, they show that blocking the activity of an enzyme called NMT in the most common malaria parasite prevents mice from showing symptoms and extends their lifespan. The team are working to design molecules that target ... more |  |

 Greek economic crisis leads to air pollution crisis Los Angeles CA (SPX) Dec 23, 2013 - In the midst of a winter cold snap, a study from researchers in the United States and Greece reveals an overlooked side effect of economic crisis - dangerous air quality caused by burning cheaper fuel for warmth. The researchers, led by Constantinos Sioutas of the USC Viterbi School of Engineering, show that the concentration of fine air particles in one of Greece's economically hardest hi ... more |  |
 Deepwater Horizon NRDA study shows possible oil impact on dolphins Washington DC (SPX) Dec 23, 2013 - Bottlenose dolphins in Louisiana's Barataria Bay have lung damage and adrenal hormone abnormalities not previously seen in other dolphin populations, according to a new peer-reviewed study published Dec. 18, 2013 in the journal Environmental Science and Technology. The Deepwater Horizon spill heavily oiled Barataria Bay. The study was conducted in August 2011 as part of the Natural Resourc ... more |  |
 DNA clamp to grab cancer before it develops Montreal, Canada (SPX) Dec 23, 2013 - As part of an international research project, a team of researchers has developed a DNA clamp that can detect mutations at the DNA level with greater efficiency than methods currently in use. Their work could facilitate rapid screening of those diseases that have a genetic basis, such as cancer, and provide new tools for more advanced nanotechnology. The results of this research is publish ... more |  |
Slippery bark protects trees from pine beetle attack Boulder CO (SPX) Dec 24, 2013 - Trees with smoother bark are better at repelling attacks by mountain pine beetles, which have difficulty gripping the slippery surface, according to a new study by the University of Colorado Boulder. The findings, published online in the journal Functional Ecology, may help land managers make decisions about which trees to cull and which to keep in order to best protect forested properties ... more |  |
 New evidence that computers change the way we learn London, UK (SPX) Dec 23, 2013 - People who use computers regularly are constantly mapping the movements of their hand and computer mouse to the cursor on the screen. Now, researchers reporting in the Cell Press journal Current Biology have shown that all that pointing and clicking (the average computer user performs an impressive 7,400 mouse clicks per week) changes the way the brain generalizes movements. "Computers pro ... more |  |

 High winds, rain lash Europe leaving two dead, one missing at sea Paris (AFP) Dec 23, 2013 - High winds and heavy rain battered parts of Europe on Monday, leaving at least two people dead and one man lost at sea off France, and disrupting travel two days from Christmas. In Britain a man was found in a swollen river in northwest England where the water was "fast flowing, and a lot more water than normal", said Inspector Chis Wright of the Cumbria police, adding: "It's fair to say tha ... more |  |
Flu vaccine more effective for women than men: study Washington (AFP) Dec 23, 2013 - The flu vaccine is generally less effective for men than for women, scientists said in a study Monday, tracing the effect to higher levels of testosterone that curb the immune response. It has long been known that men are more vulnerable than women to bacterial, viral and parasitic infections, but scientists have never been able to clearly explain why. It was also known that men don't re ... more |  |
 UN appoints two special envoys on climate United Nations, United States (AFP) Dec 23, 2013 - UN chief Ban Ki-moon announced Monday the appointment of two special envoys on climate change. Former president of Ghana John Kufuor and former prime minister of Norway Jens Stoltenberg have been asked to mobilize the "political will and action" of governments and heads of state. This will lead up to a 2015 global agreement to curb climate-altering greenhouse gas emissions and they will ... more |  |
Pollution alarm as Greeks switch to firewood for heat Athens (AFP) Dec 23, 2013 - Greek authorities on Monday offered free electricity to low-income families on certain days, after smog rose sharply as hard-hit residents increasingly shun fuel for cheaper firewood to heat their homes. The health ministry said it had finalised a plan originally announced in November that offers free power to poorer households when smog exceeds safety levels. The move came after another ... more |  |
 Uruguay will keep peacekeepers in Haiti through 2014 Montevideo (AFP) Dec 23, 2013 - Lawmakers in Uruguay on Monday voted to keep peacekeepers in Haiti through the end of 2014, but said the government would keep open the option of an earlier full withdrawal. The legislation approved in the Senate, and which had already passed in the lower house, calls for all peacekeepers to remain in the impoverished Caribbean nation until April 30, 2014. At that point, one-third of the ... more |  |

Efforts to curb climate change require greater emphasis on livestock Corvallis OR (SPX) Dec 23, 2013 - While climate change negotiators struggle to agree on ways to reduce carbon dioxide (CO2) emissions, they have paid inadequate attention to other greenhouse gases associated with livestock, according to an analysis by an international research team. A reduction in non-CO2 greenhouse gases will be required to abate climate change, the researchers said. Cutting releases of methane and nitrou ... more |  |
 Environmentalists pledge to stop Swedish wolf hunt Stockholm (AFP) Dec 20, 2013 - Swedish environmental groups on Friday vowed to block plans to cull wolves in controversial licensed hunts aimed at keeping their numbers down and potentially cutting the wolf population in half. The first hunt is scheduled for February 1, 2014 with a target of 30 wolves and will be the first licensed wolf hunt since 2011.
