• Activists in arms over plans to ship plutonium to New Mexico

    A proposal to ship tons of plutonium to New Mexico, including cores of nuclear warheads which would be dismantled at a structurally questionable lab on top of an earthquake fault zone, has activists and nuclear watchdogs up in arms

  • Los Alamos lab responds to radiological incident

    The Los Alamos National Laboratory said it is investigating the inadvertent spread of Technetium 99 by employees and contractors at the Lujan Neutron Scattering Center at the Los Alamos Neutron Science Center (LANSCE), a multidisciplinary accelerator facility used for both civilian and national security research; multiple tests indicate no health risks to public or employees

  • Cooling coal emissions would clean air, lower health, climate-change costs

    In the United States there are about 1,400 electric-generating unit powered by coal, operated at about 600 power plants; the estimated health costs of burning coal in the United States are in the range of $150 billion to $380 billion, including 18,000-46,000 premature deaths, 540,000 asthma attacks, 13,000 emergency room visits, and two million missed work or school days each year; scientists estimate that implementing large-scale cryogenic systems into coal-fired plants would reduce overall costs to society by 38 percent through the sharp reduction of associated health-care and climate-change costs

  • Maldives to build floating islands to save country from rising sea levels

    The Maldives Islands, a low-lying chain of twenty-six atolls in the Indian Ocean, are sinking; more precisely: due to global warming, the sea level is rising over the islands, most of which sit lower than three feet above the rising water; the Maldives government has embarked on an ambitious project: build floating islands, anchor them to the ocean floor, then relocate most of the population of 300,000 – and some of the tourist attractions – to them

  • Electric plants challenged by high temperatures, drought

    The hottest July on record since 1895, along with the most wide-spread drought in the country since 1956, have nuclear plants struggling with finding enough water — cool water — to keep key parts of the plants cool; if the water gets too warm, operators have to dial back production — for reactor safety, and also to regulate the temperature of discharge water, which affects aquatic life

  • No-till could help stabilize crop yields despite climate change

    Reducing tillage for some Central Great Plains crops could help conserve water and reduce losses caused by climate change, according to studies at the U.S. Department of Agriculture

  • Mystery of dramatic leveling off of methane in the atmosphere solved

    Increased capture of natural gas from oil fields probably accounts for up to 70 percent of the dramatic leveling off seen in atmospheric methane at the end of the twentieth century; methane has twenty times the global warming potential of carbon dioxide, although CO2 is filling the atmosphere in far larger amounts

  • World could be in for higher food prices

    This has been one of the driest summers in American history, but the weather is not only affecting the United States; weak monsoons in India and other weather issues across the globe are affecting crops and could lead to higher food prices in 2013

  • Geoengineering clouds to slow global warming

    Researchers are taking a second look at the possibility of using futuristic ships to shoot salt water high into the sky over the oceans, creating clouds that reflect sunlight and thus counter global warming; The theory behind idea, called “marine cloud brightening,” is that adding particles, in this case sea salt, to the sky over the ocean would form large, long-living clouds

  • Bacteria in tap water traced to the water treatment process

    Most of the bacteria that remain in drinking water when it gets to the tap can be traced to filters used in the water treatment process, rather than to the aquifers or rivers where they originated; the findings could open the door to more sustainable water treatment processes that use fewer chemicals and, as a result, produce lower levels of byproducts that may pose health risks; eventually, the work could enable engineers to control the types of microbes in drinking water to improve human health

  • Greenland melting breaks record four weeks early – with two weeks more to go

    Melting over the Greenland ice sheet shattered the seasonal record on 8 August — a full four weeks before the close of the melting season; with more melting yet to come in August, this year’s overall melting will fall way above the old records; researchers devise a “cumulative melting index,” which measures the type of melting which adds to the runoff of melt-water that makes sea levels rise

  • Toilet Challenge, 1: Caltech’s solar-powered toilet wins Reinvent Toilet Challenge

    The World Health Organization reports that 2.5 billion people around the globe are without access to sanitary toilets, which results in the spread of deadly diseases; every year, 1.5 million people, mostly those under the age of five, die from diarrhea; Caltech scientist awarded grant to develop solar-powered sanitation system

  • Toilet Challenge, 2: Loughborough’s hydrocarbonization design wins second Reinvent the Toilet Challenge prize

    Researchers from Loughborough University, located in Leicestershire, United Kingdom , won second prize in the Reinvent the Toilet Challenge; their toilet uses a process called Continuous Thermal Hydrocarbonization which kills all pathogens to create safe to handle, valuable material and uses power from heat generated during processing

  • Toilet Challenge, 3: U Toronto wins toilet challenge third place for sand filter and UV-ray design

    The U of T solution is novel in its simplicity. It uses a sand filter and UV-ray disinfecting chamber to process liquid waste and a smolder chamber, similar to a charcoal barbeque, to incinerate solid waste that has been flattened and dried in a roller/belt assembly

  • New earthquake assessment finds increased risk for Washington Dams

    Central Washington state has always been considered low risk for earthquakes back when big hydropower dams went up on the Columbia River many decades ago; a recently completed seismic hazard assessment, however, shows that there is a much greater earthquake potential for the area than previously thought; now, dam owners have to figure out whether their dams can hold up to an earthquake; if retrofits are needed, they could cost hundreds of millions of dollars
