The study, recently published in the journal Biogeosciences, provides data that will help researchers better understand the Arctic Ocean's carbon cycle -- the pathway through which carbon enters and is used by the marine ecosystem.... Researchers aim to assemble the tree of life for all 2 million named species - (iNational Evolutionary Synthesis Center (NESCent)/i) A new initiative aims to build a tree of life that brings together everything scientists know about how living things are related, from the tiniest bacteria to the tallest tree. Scientists have been building evolutionary trees for more than 150 years. But despite significant progress, there is still no central place where researchers can browse and download the entire tree. Now, a team of researchers aims to make that a reality.... Toxic mercury, accumulating in the Arctic, springs from a hidden source - (iHarvard University/i) Environmental scientists at Harvard have discovered that the Arctic accumulation of mercury, a toxic element, is caused by both atmospheric forces and the flow of circumpolar rivers that carry the element north into the Arctic Ocean. While the atmospheric source was previously recognized, it now appears that twice as much mercury actually comes from the rivers. The revelation implies that concentrations of the toxin may further increase as climate change continues to modify the region's hydrological cycle and release mercury from warming Arctic soils.... How plants chill out - (iUniversity of Bristol/i) Plants elongate their stems when grown at high temperature to facilitate the cooling of their leaves, according to new research from the University of Bristol published today in Current Biology. Understanding why plants alter their architecture in response to heat is important as increasing global temperatures pose a threat to future food production....

Pollution teams with thunderclouds to warm atmosphere - (iDOE/Pacific Northwest National Laboratory/i) Pollution is warming the atmosphere through summer thunderstorm clouds, according to a computational study published May 10 in Geophysical Research Letters. How much the warming effect of these clouds offsets the cooling that other clouds provide is not yet clear. To find out, researchers need to incorporate this new-found warming into global climate models....

Stanford scientists document fragile land-sea ecological chain - (iStanford University/i) Intricate, often invisible chains of life are threatened with extinction around the world. A new study quantifies one of the longest such chains ever documented.... Finding fingerprints in sea level rise - (iHarvard University/i) As described in a paper in the Proceedings of the National Academy of Sciences, graduate students Eric Morrow and Carling Hay demonstrate the use of a statistical tool called a Kalman smoother to identify sea level fingerprints -- tell-tale variations in sea level rise -- in a synthetic data set. Using those fingerprints, scientists can determine where glacial melting is occurring.... DNA barcoding verified the discovery of a highly disconnected crane fly species - (iPensoft Publishers/i) Finnish and Russian entomologists have discovered a new crane fly species on the Eurasian continent. The new species, Tipula recondita, has been documented in both Finnish Lapland and the Russian Far East in two apparently disconnected populations. The description was published in the open-access journal ZooKeys.... Geosphere introduces a new special issue theme - (iGeological Society of America/i) Geosphere articles posted May 17 include an introduction to the new theme; a multifaceted study of the formation and transport of ancient oceanic rocks now found in southeastern Yukon, Canada; a new technique to help find the initial age of a multiply reactivated fault; and bathymetry studies of unusual flat-topped seafloor mounds beneath the Ross Sea that the authors believe are of volcanic origin, erupted during a geomagnetic reversal and under a grounded ice sheet.... Visualizing the imprints of past and present Earth dynamics - (iGeological Society of America/i) New Lithosphere articles posted online May 16, 2012, report on (1) seismic anisotropy measured beneath 14 broadband stations in southeastern India; why geoscientists should persist in their efforts to reach and study such spectacular sub-sea geologic features as the Mariana Trench (recently explored by film director James Cameron) and how land geologists can help this effort by studying on-land equivalents like ophiolites; and (3) pressures and melting temperatures of sediments deeply buried in Earth's mantle.... UF researchers name new extinct giant turtle found near world's largest snake - (iUniversity of Florida/i) University of Florida researchers have described a new extinct giant turtle species from the same Colombian mine where they discovered Titanoboa -- and one of the only animals the world's largest snake could not have eaten.... Climate engineering report ranked among top government priorities by Copenhagen Consensus Center - (iUniversity of Texas at Austin/i) The effect of global warming could potentially be ameliorated by engineering ways to reflect more sunlight back into space, according to a report by a professor at the University of Texas at Austin.The report, by Professor J. Eric Bickel and Hudson Institute Fellow Lee Lane, was selected by a panel of international experts as one of 16 areas of research that governments and philanthropists should prioritize to respond to the world's most pressing challenges.... Germany's energy transition: 1 year later - (iGerman Center for Research and Innovation/i) After the Fukushima nuclear explosions, Germany responded to the heightened international focus on energy procurement by returning to a fast-paced nuclear phase-out program. On May 21, a lunch discussion at the German Center for Research and Innovation will address the mechanisms for achieving these goals and describe plans for assessing the program's success.... Ancient giant turtle fossil revealed - (iNorth Carolina State University/i) Picture a turtle the size of a Smart car, with a shell large enough to double as a kiddie pool.... Could cap and trade for water solve problems facing the United States' largest rivers? - (iWiley-Blackwell/i) Lake Mead, on the Colorado River, is the largest reservoir in the United States, but users are consuming more water than flows down the river in an average year, which threatens the water supply for agriculture and households. To solve this imbalance scientists are proposing a Cap and Trade system of interstate water trading. The proposal, published in Journal of the American Water Resources Association, builds on the success of such an initiative in Australia.... Bay Area PV Consortium announces $7.5 million in grants to lower the cost of large-scale solar - (iStanford University/i) The Bay Area Photovoltaic Consortium -- an industry-supported program led by Stanford University and the University of California-Berkeley -- has announced its first research grants aimed at making utility-scale solar power cost-competitive by the end of the decade.... Abundance of rare DNA changes following population explosion may hold clues to common diseases - (iUniversity of Washington/i) Scientists have taken a first step toward understanding how rare genetic differences among people contribute to leading chronic illnesses. One-letter DNA code changes occur frequently in human genomes, but each variant is usually found in only a few individuals. This phenomenon is consistent with the population explosion of the past 5,000 years. Studying the evolution of rare genetic variants and their health impact is critical as low cost, rapid sequencing enters clinical use. Such information would help doctors interpret personal genomes....
