• China’s Mekong River dams undermine neighbors’ economies, food production

    Five Chinese dams on the Mekong River’s upper portions have caused rapid changes in water level, and other adverse effects, downstream, especially in Vietnam, Cambodia, Thailand, and Laos, where millions of people rely on the river for water, food, and transportation

  • Carbon dioxide “corrodes” ice, causing glaciers, ice caps to crack

    The amount of carbon dioxide in the atmosphere has risen from roughly 280 ppm shortly before the industrial revolution to about 390 ppm today; now researchers done atom-level simulations that suggest that increased concentrations of the gas causes ice to become more brittle, and so more likely to break up or crack; this explains the cracking of glaciers and ice caps

  • U.S. keeps collecting money for a nuclear waste repository – but has no plans to build one

    Illinois utility customers have paid the U.S government $1.9 billion to store spent nuclear fuel from nuclear plants in the state in a permanent national nuclear waste repository; in the last thirty years, the U.S. government has collected $30 billion from utilities toward this permanent storage, and it keeps collecting $750 million a year; trouble is, in February 2009 the Obama administration decided to “defund” the Yucca Mountain nuclear repository project, and the U.S. government no longer has active plans for a centralized nuclear waste storage facility

  • Green laser pointer identifies traces of dangerous chemicals in real time

    By using an ordinary green laser pointer, the kind commonly found in offices and college lecture halls, an Israeli research team has developed a new and portable Raman spectrometer which can detect minute traces of hazardous chemicals in real time; the new sensor’s compact design makes it a candidate for rapid field deployment to disaster zones and areas with security concerns

  • Cutting food losses in half would feed an additional billion people

    More efficient use of the food production chain and a decrease in the amount of food losses will dramatically help maintaining the planet’s natural resources and improve people’s lives; researchers have proved a valid estimation, for the first time, for how many people could be fed with reducing food losses

  • Study maps greenhouse gas emissions down to building, street level for U.S. cities

    Researchers have developed a new software system capable of estimating greenhouse gas emissions across entire urban landscapes, all the way down to roads and individual buildings. Until now, scientists quantified carbon dioxide (CO2) emissions at a much broader level

  • New methods might drastically reduce the costs of investigating polluted sites

    In Europe there are over 20,000 complex and large contaminated areas. These so-called megasites threaten scarce land and water resources, create environmental and health risks, and result in economic and social costs; new methods may allow polluted sites to be investigated and monitored long term at significantly reduced costs

  • NRC sees no evidence of bad security practices at Michigan nuclear plant

    The Nuclear Regulatory Committee (NRC) released  information last week about a leak earlier this summer at the Palisades plant near South Haven, Michigan; the plant has been mired in controversy this year, as at least three water leaks have occurred in the past several months, and the plant has one of the worst safety ratings in the United States

  • Environmentalists concerned about earthquakes tests near California nuclear plant

    The Pacific Gas and Electric Company (PG&E) wants to use air guns to emit strong sound waves into a large near-shore area which includes parts of marine reserves; the purpose: creating three dimensional maps of fault zones near its Diablo Canyon nuclear plant in California; the plans have federal and state officials concerned about marine life and public safety

  • Dallas area earthquakes were caused by fracking: geophysicists

    Three earthquakes that hit a Dallas suburb last week could be connected to fracking operations, according to a local geophysicist who studies earthquakes in the region; the earthquakes were considered minor, with the biggest one registered at a 3.4 on the Richter scale; no injuries were reported despite many emergency calls

  • CO2 emissions as a result of economic growth, decline not symmetrical

    Estimating the trajectory of CO2 emissions, an important part of planning for climate change mitigation and adaptation, depends in part on understanding how these emissions are influenced by the economy; new study finds that in years when GDP per capita shrinks, CO2 emissions per capita do not decline in equal proportion to the amount by which they increase with economic growth

  • Camera for long-range gas leak detection

    New infrared gas imaging camera equipped with a 75 mm lens; it iscertified for use in Class I Div 2 hazardous locations, enabling remote detection and visualization of gas leaks from a great distance

  • April 2012 Indian Ocean earthquake indicate s that a new tectonic plate is being born

    The 11 April 2012 8.7 magnitude earthquake in the Indian Ocean, unlike its 2004 predecessor, did very little damage; it began at one fault, and when it reached an intersecting fault, it ruptured; in total, four different faults were ruptured over the course of 150 seconds; when earthquakes spread to connecting faults, the rupture rips along faults that branch away from the initial fault like branches of a river; the April 2012 earthquakes took a very different course, running along grid-like patterns and making 90 degree turns; the weird rupture pattern reflects the fact that the region is giving birth to a new tectonic plate

  • City of Ottawa sits atop soft soil, a geologic features which amplifies seismic waves

    Roughly 20 percent of the Ottawa area is built on bedrock, while the remaining area contains unconsolidated surface deposits; this is not good news for city planners – and dwellers – because soft soil amplifies seismic waves, resulting in stronger ground motion than for sites built over bedrock

  • Innovative, “complete” solution for oil-spill cleanup

    Corncobs, straw, and other absorbents used to clean up oil spills can hold only about five times their own weight and pick up water, as well as oil; scientists describe what may be a “complete solution” to cleaning up oil spills — a superabsorbent material that sops up forty times its own weight in oil and then can be shipped to an oil refinery and processed to recover the oil
