 Late Cretaceous Period was likely ice-free Columbia, MO (SPX) Sep 27, 2013 - For years, scientists have thought that a continental ice sheet formed during the Late Cretaceous Period more than 90 million years ago when the climate was much warmer than it is today. Now, a University of Missouri researcher has found evidence suggesting that no ice sheet formed at this time. This finding could help environmentalists and scientists predict what the earth's climate will be as ... more |  |
 A fast fish with a huge impact Munich, Germany (SPX) Sep 27, 2013 - Globalization is breaking down barriers - also for plants and animals on the lookout for new homes. Rivers are also changing, in particular through the introduction of non-native species, often brought in by passing ships. In the Danube River, scientists have been observing a fish species conquering a new habitat and creating a totally new ecosystem in the process. Recent decades have seen ... more |  |
Chasing the black holes of the ocean Zurich, Switzerland (SPX) Sep 27, 2013 - According to researchers from ETH Zurich and the University of Miami, some of the largest ocean eddies on Earth are mathematically equivalent to the mysterious black holes of space. These eddies are so tightly shielded by circular water paths that nothing caught up in them escapes. The mild winters experienced in Northern Europe are thanks to the Gulf Stream, which makes up part of those o ... more |  |
 Northern moths may fare better under climate warming than expected Hanover NH (SPX) Sep 27, 2013 - Moths in northern Finland are less susceptible to rising temperatures than expected, suggesting high latitude moth populations around the world may be partly buffered from the effects of rapid climate warming, according to a new Dartmouth-Finnish study based on the most extensive analyses yet conducted of seasonal patterns in forest animals. The results are important because moths are a ke ... more |  |
 Uphill for the trees of the world Aarhus, Denmark (SPX) Sep 27, 2013 - Human civilisation has had an impact on the world, and it continues to have an even greater impact. One of these is that the forests have been cleared and especially so in flat lowlands, so that they have gradually become restricted to steep terrain. This pattern is now emerging all across the world. Developed countries have been particularly efficient at removing forests from fertile, fla ... more |  |

Fossil record shows crustaceans vulnerable as modern coral reefs decline Gainesville FL (SPX) Sep 27, 2013 - Many ancient crustaceans went extinct following a massive collapse of reefs across the planet, and new University of Florida research suggests modern species living in rapidly declining reef habitats may now be at risk. Available online and scheduled to appear in the November issue of Geology, the study shows a direct correlation between the amount of prehistoric reefs and the number of de ... more |  |
Wind and rain belts to shift north as planet warms New York NY (SPX) Sep 27, 2013 - As humans continue to heat the planet, a northward shift of Earth's wind and rain belts could make a broad swath of regions drier, including the Middle East, American West and Amazonia, while making Monsoon Asia and equatorial Africa wetter, says a new study in Proceedings of the National Academy of Sciences. The study authors base their prediction on the warming that brought Earth out of ... more |  |
 Modifying Rice Crops to Resist Herbicide Prompts Weedy Neighbors' Growth Spurt Columbus OH (SPX) Sep 27, 2013 - Rice containing an overactive gene that makes it resistant to a common herbicide can pass that genetic trait to weedy rice, prompting powerful growth even without a weed-killer to trigger the modification benefit, new research shows. Previously, scientists have found that when a genetically modified trait passes from a crop plant to a closely related weed, the weed gains the crop's enginee ... more |  |
 Sonar mapping for oil killed Madagascar whales: study Washington (AFP) Sept 26, 2013 - A noisy technology that blasts high-frequency sounds below water to map the ocean for oil probably caused the deaths of 75 melon-headed whales off Madagascar, experts said Thursday. An independent panel of scientists found that sonar surveying by ExxonMobil in late May 2008 led to the sudden displacement of around 100 whales, of which at least three-quarters died. "This is the first kno ... more |  |
 Storm-stricken Acapulco hit by new floods Acapulco, Mexico (AFP) Sept 26, 2013 - Authorities in Acapulco closed schools and evacuated dozens of residents Thursday after heavy rains sparked new floods in the Mexican Pacific resort still reeling from deadly tropical storms. Flooding was reported in at least 22 city districts and the main boulevard to the airport was closed after a lagoon overflowed, though the terminal remained in operation, officials said. Around 40 p ... more |  |

2008 mass whale stranding attributed to sonar mapping, researchers say Antananarivo, Madagascar (UPI) Sep 26, 2013 - A mass whale stranding in Loza Lagoon off Madagascar on 2008 has been attributed to high-frequency mapping sonar systems, researchers said. An investigatory team determined the stranding of 100 melon-headed whales was caused by an echo-sounder system operated by a survey vessel, Science Recorder reported Thursday. When the stranding occurred, the Wildlife Conservation Society wor ... more |  |
 Pakistan quake survivors face long wait for aid Awaran, Pakistan (AFP) Sept 26, 2013 - Tens of thousands of survivors of Pakistan's earthquake waited for help in soaring temperatures Thursday, as the death toll rose past 350 and anger grew at the slow pace of government aid. More than 100,000 people made homeless by Tuesday's 7.7-magnitude quake spent a second night in the open or under makeshift shelters as response teams struggled to reach the remote region in the southweste ... more |  |
 Chile ruling to keep Barrick mine closed to late 2014 Montreal (AFP) Sept 26, 2013 - Chile's high court has upheld an order temporarily suspending construction of what would be the world's biggest gold mine over environmental concerns, Canadian mining firm Barrick Gold announced Thursday. The multi-billion dollar Pascua-Lama project, which straddles Chile's border with Argentina at an altitude of 4,000 meters (13,200 feet), was launched in 2009. But local groups launched ... more |  |
 Study finds 'microbial clock' may help determine time of death Boulder, Colo. (UPI) Sep 26, 2013 - A so-called microbial clock may help determine the time a person dies, research led by the University of Colorado-Boulder indicates. The clock is essentially the succession of bacterial changes occurring postmortem as bodies go through the decay process, the university said in a release. Researchers used mice for the latest study, but previous studies on the human microbiome - t ... more |  |
