 NASA Reveals New Results From Inside the Ozone Hole Greenbelt MD (SPX) Dec 12, 2013 - NASA scientists have revealed the inner workings of the ozone hole that forms annually over Antarctica and found that declining chlorine in the stratosphere has not yet caused a recovery of the ozone hole. More than 20 years after the Montreal Protocol agreement limited human emissions of ozone-depleting substances, satellites have monitored the area of the annual ozone hole and watched it ... more |  |
 Study finds biomaterials repair human heart Clemson SC (SPX) Dec 12, 2013 - Clemson University biological sciences student Meghan Stelly and her father, Alabama cardiovascular surgeon Terry Stelly, investigated a biomedical application following a coronary artery bypass surgery and found that the application allowed the human body to regenerate its own tissue. The biomaterial extracellular matrix (ECM) is a naturally occurring substance that helps regulate cells a ... more |  |
 East Antarctica is sliding sideways San Francisco CA (SPX) Dec 12, 2013 - It's official: East Antarctica is pushing West Antarctica around. Now that West Antarctica is losing weight--that is, billions of tons of ice per year--its softer mantle rock is being nudged westward by the harder mantle beneath East Antarctica. The discovery comes from researchers led by The Ohio State University, who have recorded GPS measurements that show West Antarctic bedrock is bein ... more |  |
 What the past tells us about modern sea-level rise Southampton, UK (SPX) Dec 12, 2013 - Researchers from the University of Southampton and the Australian National University report that sea-level rise since the industrial revolution has been fast by natural standards and - at current rates - may reach 80cm above the modern level by 2100 and 2.5 metres by 2200. The team used geological evidence of the past few million years to derive a background pattern of natural sea-level r ... more |  |
 How Bats Took Over the Night Tel Aviv, Israel (SPX) Dec 13, 2013 - Blessed with the power of echolocation - reflected sound - bats rule the night skies. There are more than 1,000 species of these echolocating night creatures, compared with just 80 species of non-echolocating nocturnal birds. And while it seems that echolocation works together with normal vision to give bats an evolutionary edge, nobody knows exactly how. Now Dr. Arjan Boonman and Dr. Yoss ... more |  |

Arctic cyclones more common than previously thought San Francisco CA (SPX) Dec 12, 2013 - From 2000 to 2010, about 1,900 cyclones churned across the top of the world each year, leaving warm water and air in their wakes-and melting sea ice in the Arctic Ocean. That's about 40 percent more than previously thought, according to a new analysis of these Arctic storms. A 40 percent difference in the number of cyclones could be important to anyone who lives north of 55 degrees latitud ... more |  |
 Not all species age the same; humans may be outliers Orlando, FL (SPX) Dec 12, 2013 - Adult humans get weaker as they age and then die, but that's not the typical pattern across species. Some organisms don't appear to show signs of aging at all. These are among the findings in a first-of-its-kind study published in the journal Nature this week. The study compares the aging patterns of humans and 45 other species. "We all have preconceived notions about aging and what ... more |  |
 Global map to predict giant earthquakes Melbourne, Australia (SPX) Dec 13, 2013 - A team of international researchers, led by Monash University's Associate Professor Wouter Schellart, have developed a new global map of subduction zones, illustrating which ones are predicted to be capable of generating giant earthquakes and which ones are not. The new research, published in the journal Physics of the Earth and Planetary Interiors, comes nine years after the giant earthqu ... more |  |
 Scientists map food security and self-provision of major cities Copenhagen, Denmark (SPX) Dec 12, 2013 - Wealthy capital cities vary greatly in their dependence on the global food market. The Australian capital Canberra produces the majority of its most common food in its regional hinterland, while Tokyo primarily ensures its food security through import. The Copenhagen hinterland produces less than half of the consumption of the most common foods. For the first time, researchers have mapped ... more |  |
Study demonstrates that indigenous hunting with fire helps sustain Brazil's savannas Bloomington, IN (SPX) Dec 12, 2013 - Indigenous use of fire for hunting is an unlikely contributor to long-term carbon emissions, but it is an effective environmental management and recovery tool against agribusiness deforestation, a new study from Indiana University and Brazil's Oswaldo Cruz Foundation has found. Many indigenous peoples in Brazil have practiced hunting with fire, and today Brazil's Xavante Indians often use ... more |  |

 Young tropical forests contribute little to biodiversity conservation Panama City, Panama (SPX) Dec 13, 2013 - A satellite image of a green swath of tropical forest does not tell the whole story. About half the world's tropical forests are relatively young. Unless protected, they are unlikely to last more than a human generation before falling to bulldozers and chainsaws. These ephemeral secondary forests may contribute little to tree-biodiversity conservation, according to a new report by scientists at ... more |  |
 Winter storm pummels Mideast, adding to refugee misery Beirut (AFP) Dec 12, 2013 - A bruising winter storm brought severe weather to the Middle East Thursday, forcing the closure of roads and schools and blanketing already miserable Syrian refugee camps with snow. The nearly three-year-old conflict in Syria has killed an estimated 126,000 people and displaced millions, including more than two million who have fled across the borders and thousands who are living in makeshif ... more |  |
Ice melt means greener Arctic is the new normal Washington (AFP) Dec 12, 2013 - Below-average snow cover, melting sea ice and declines in the population of reindeers and caribou are the new normal in the modern-day Arctic, said a scientific report out Thursday. While this year was not as extreme as 2012, the trend toward a warming planet means these changes are likely here to stay, said the Arctic Report Card 2013, issued by the National Oceanic and Atmospheric Administ ... more |  |
European Parliament approves fishing reforms, discards ban Strasbourg, France (UPI) Dec 12, 2013 - The European Parliament this week gave final approval to fishing sustainability reforms that include banning the practice of discarding unwanted fish at sea. Changes to the EU's Common Fisheries Policy aimed at preventing overfishing were approved in a plenary vote Tuesday in Strasbourg, France and will take effect Jan. 1. Key among them is a discard ban, which was sought by the ... more |  |
 Desperate Syrians find little comfort in new homes Beirut (AFP) Dec 12, 2013 - They fled air strikes and shelling, but many of Syria's three million refugees have found little comfort elsewhere, suffering in squalid camps and risking death to reach Europe's shores. In Lebanon, many crowd into makeshift shelters in agricultural fields that will soon be blanketed in thick snow, and in Egypt they have faced government crackdowns and deportation. A lucky few have found ... more |  |

Evidence of ancient supervolcano found in Utah Provo, Utah (UPI) Dec 11, 2013 - Geologists in Utah report they've had to look no further than their back yard for evidence of some of the largest volcanic eruptions in Earth's history. Researchers from Brigham Young University say the supervolcanoes are no longer active, but 30 million years ago they spewed almost 2 million cubic feet of magma during a one-week period near a place called Wah Wah Springs in west-centra ... more |  |
Not all species age the same, and humans are outside the norm Orlando, Fla. (UPI) Dec 11, 2013 - Not all species age the same, U.S. researchers say, and humans may be outside the norm because adult humans get weaker as they age and then die. That's not the typical pattern across species, scientists at the University of Central Florida said, and some organisms don't appear to show signs of aging at all. In a study published in the journal Nature, the researchers described the ... more |  |

Pentagon chief Chuck Hagel also warned Kiev against using military force on demonstrators "in any fashion," and urged restraint. "We are considering policy options, there obviously has not been a decision made, sa ... more |  |
Snowstorm brings new misery for Syria refugees Saadnayel, Lebanon (AFP) Dec 12, 2013 - Syrian refugee Faisal looks down at the muddy floor of his tent in a field in eastern Lebanon as it is battered by a snowstorm. "I'd rather die a million times than live through this humilation," the 48-year-old says bitterly. "Nobody else has had to go through what's happening to us. Every country is plotting against us, they're all traitors," Faisal rages, his head wrapped in a scarf. ... more |  |
Turkey ex-army chief denies 1997 coup role Ankara (AFP) Dec 12, 2013 - A former Turkish army chief denied Thursday that the military overthrow of the country's first Islamist prime minister in 1997 was tantamount to a coup. General Ismail Hakki Karadayi, who has been charged with 102 others, appeared in court in Ankara for the first time since the start of the trial in September over what has been dubbed Turkey's "post-modern coup". Karadayi, 81, who failed ... more |  |
