 Methane climate change risk suggested by proof of redox cycling of humic substances Marburg, Germany (SPX) Apr 23, 2014 - The recent Yokahama IPCC meeting painted a stark warning on the possible effects of gases such as methane - which has a greenhouse effect 32 times that of carbon dioxide. Now a team of Swiss-German researchers have shown that humic substances act as fully regenerable electron acceptors which helps explain why large amount of methane are held in wetlands instead of being released to the atm ... more |  |
 Long-term predictions for Miami sea level rise could be available relatively soon Washington DC (SPX) Apr 23, 2014 - Miami could know as early as 2020 how high sea levels will rise into the next century, according to a team of researchers including Florida International University scientist Rene Price. Price is also affiliated with the National Science Foundation's (NSF) Florida Coastal Everglades Long-Term Ecological Research (LTER) site, one of 25 such NSF LTER sites in ecosystems from coral reefs to d ... more |  |
 Taking the pulse of mountain formation in the Andes Rochester NY (SPX) Apr 23, 2014 - Scientists have long been trying to understand how the Andes and other broad, high-elevation mountain ranges were formed. New research by Carmala Garzione, a professor of earth and environmental sciences at the University of Rochester, and colleagues sheds light on the mystery. In a paper published in the latest Earth and Planetary Science Letters, Garzione explains that the Altiplano plat ... more |  |
 Lab researcher discovers the green in Greenland Livermore CA (SPX) Apr 23, 2014 - At one point in history, Greenland was actually green and not a country covered in ice. An international team of researchers, including a former scientist from Lawrence Livermore National Laboratory, has discovered that ancient dirt in Greenland was cryogenically frozen for millions of years under nearly two miles of ice. More than 2.5 million years ago. Greenland looked like the green Ala ... more |  |
 Ancient shark fossil reveals new insights into jaw evolution Washington DC (SPX) Apr 23, 2014 - The skull of a newly discovered 325-million-year-old shark-like species suggests that early cartilaginous and bony fishes have more to tell us about the early evolution of jawed vertebrates-including humans-than do modern sharks, as was previously thought. The new study, led by scientists at the American Museum of Natural History, shows that living sharks are actually quite advanced in evo ... more |  |

 Chickens to chili peppers Panama City, Panama (SPX) Apr 23, 2014 - Suddenly there was a word for chili peppers. Information about archaeological remains of ancient chili peppers in Mexico along with a study of the appearance of words for chili peppers in ancient dialects helped researchers to understand where jalapenos were domesticated and highlight the value of multi-proxy data analysis. Their results are from one (Kraig Kraft et al.) of nine papers pre ... more |  |
Researchers question published no-till soil organic carbon sequestration rates Urbana IL (SPX) Apr 23, 2014 - For the past 20 years, researchers have published soil organic carbon sequestration rates. Many of the research findings have suggested that soil organic carbon can be sequestered by simply switching from moldboard or conventional tillage systems to no-till systems. However, there is a growing body of research with evidence that no-till systems in corn and soybean rotations without cover crops, ... more |  |
New technique will accelerate genetic characterization of photosynthesis Stanford, CA (SPX) Apr 23, 2014 - Photosynthesis provides fixed carbon and energy for nearly all life on Earth, yet many aspects of this fascinating process remain mysterious. For example, little is known about how it is regulated in response to changes in light intensity. More fundamentally, we do not know the full list of the parts of the molecular machines that perform photosynthesis in any organism. A type of single-ce ... more |  |
Anne Douglass - Thinks Like a Scientist Greenbelt MD (SPX) Apr 23, 2014 - When faced with a complex problem, Aura project scientist and co-lead for the Chemistry Climate Model Anne Douglass instructs herself to think like a scientist. What do you do and what is most interesting about your role here at Goddard? How do you help support Goddard's b>mission? br> /b> I have two roles. As Aura project scientist, my deputies, Joanna Joiner and Bryan Duncan, and ... more |  |
Today's Antarctic region once as hot as California, Florida New Haven CT (SPX) Apr 23, 2014 - Parts of ancient Antarctica were as warm as today's California coast, and polar regions of the southern Pacific Ocean registered 21st-century Florida heat, according to scientists using a new way to measure past temperatures. The findings, published the week of April 21 in the Proceedings of the National Academy of Sciences, underscore the potential for increased warmth at Earth's poles an ... more |  |

 Chimpanzees prefer firm, stable beds Washington DC (SPX) Apr 23, 2014 - Chimpanzees may select a certain type of wood, Ugandan Ironwood, over other options for its firm, stable, and resilient properties to make their bed, according to a study published April 16, 2014 in the open-access journal PLOS ONE by David Samson from the University of Nevada and Kevin Hunt from Indiana University. Chimpanzees use tree branches to build beds or nests in trees. They select ... more |  |
Florida is 'Ground Zero' for sea level rise Miami Beach, United States (AFP) April 22, 2014 - Warm sunshine and sandy beaches make south Florida and its crown city, Miami, a haven for tourists, but the area is increasingly endangered by sea level rise, experts said Tuesday. During a special Senate hearing held in Miami Beach, Senator Bill Nelson described south Florida as "Ground Zero" for climate change and its threats to coastal communities. The perils for Miami are particularl ... more |  |
 Everest guides abandon climbing season after deadly avalanche Kathmandu (AFP) April 22, 2014 - Nepalese guides on Mount Everest said Tuesday they would abandon this year's climbing season to honour 16 colleagues killed in an avalanche last week, throwing hundreds of mountaineers' plans into chaos. Scores of foreign climbers have been waiting in base camp after paying tens of thousands of dollars to scale the world's highest peak. The sherpas perform essential tasks on the 8,848-me ... more |  |
 Monkey study explores evolution of mathematic reasoning Cambridge, Mass. (UPI) Apr 22, 2013 - Scientists have known that monkeys and other mammals are capable of basic arithmetic. But how far can mathematical reasoning skills can be traced back in human evolution? Scientists recently attempted to find out by successfully teaching rhesus macaques to identify symbols - the 10 Arabic numerals and 16 letters - representing the numbers zero to 25. Each symbol was associated ... more |  |
Scientists discover oldest footprints outside of Africa Happisburgh, England (UPI) Apr 22, 2013 - A new study published in PLOS ONE details the oldest human footprints found outside of Africa. Found and studied by archaeologists from the British Museum, the footprints are estimated to be anywhere from 780,000 to one million years old. The footprints were discovered pressed into estuary mudflats along the coast of Happisburgh, England, a small village in low-lying Norfolk coun ... more |  |
