• DHS chemical plant security program hobbled by problems, poor oversight

    A DHS program responsible for the security of chemical facilities, such as the West Fertilizer Company plant in Texas, has been ineffective owing to a number of issues, leading federal investigators to wonder “whether it can achieve its mission, given the challenges the program continues to face.”

  • U.S. policy may lead to growing global shortage of helium

    Helium is an essential resource in technologies such as medical imaging, rocket engines, and surveillance devices. In response to the element’s scarcity, the United States has been stockpiling helium since the 1960s in a National Helium Reserve called the Bush Dome, a deep underground reservoir outside of Amarillo, Texas. In 1996 the Helium Privatization Act mandated that the Department of the Interior sell off all the stockpiled helium by 2015. Scientists say that this action discourages the active exploration of helium since companies can buy it from the United States at a cheap price and sell it at a premium. The result will be a growing shortage of helium.

  • Smartphone app locates gunfire source

    For the last decade, the Department of Defense has spent millions of dollars to develop sophisticated sniper location systems which are installed in military vehicles and require dedicated sensor arrays. Scientists have now developed a smartphone app that tracks gunfire and points in the direction the shot came from.

  • New fertilizer can be used to grow food – but not build bombs

    Ammonium nitrate fertilizer is used in agriculture, but when mixed with a fuel such as diesel, it is highly explosive. It was used in about 65 percent of the 16,300 homemade IEDs in Afghanistan in 2012.About 1,900 troops were killed or wounded in IED attacks in 2012, 60 percent of American combat casualties. There have been more than 17,000 global IED incidents in 123 countries in the past two years. Timothy McVeigh used ammonium nitrate in Oklahoma City in 1995. Scientists have developed a fertilizer that helps plants grow but cannot detonate a bomb.

  • EPA slams State Department’s Keystone XL pipeline review

    The Environmental Protection Agency (EPA) on Monday criticized the State Department’s environmental impact review of the Keystone XL pipeline, saying there was not enough evidence to back up key conclusions in the review on emissions, safety, and alternative routes. The EPA’s comments could have a negative effect on the approval of the project, but if the project is approved, the comments could serve as supporting evidence in any ligation against the pipeline.

  • River beds keep moving, increasing flood risk

    A detailed study of shifting river beds could hold the key to more accurate flood prevention. It is commonly believed that the elevation of river beds is more or less constant, so any change in flood risk is due to changes in hydrology. Researchers find, however, that there is a significant trends in the elevation of river beds, an indication that river channels are filling in with sediment or that sediment is being eroded through time.

  • DOE seizes $21 million from Fisker after company fails to make monthly payment on loan

    The administration seized $21 million from auto company Fisker Automotive, less than a month after the automaker laid off three quarters of its employees due to financial and production problems. Fisker, based in Anaheim, California, was awarded a $192 million loan as part of a program started by the Obama administration to boost electric cars and other alternative-fuel vehicles.

  • Winner announced in the first DARPA FANG Challenge

    The Ground Systems team outpaces more than 200 teams and 1,000 participants, submitting the winning mobility in the Fast Adaptable Next-Generation Ground Vehicle (FANG) Mobility/Drivetrain Challenge, and drivetrain subsystem design and claiming the $1 million prize.

  • U.S. science teachers are not fully prepared for new science teaching standards

    New voluntary guidelines for science education were unveiled earlier this month by the advocacy group Achieve in collaboration with twenty-six states. The new standards call for more hands-on learning and analysis and cover fewer science topics, but in greater depth.A new report says, however, that America’s K-12 teachers are not fully prepared to meet a new set of science standards.

  • New submarine hunting program reaches milestones

    DARPA’s Distributed Agile Submarine Hunting (DASH) Program has tested two complementary prototype systems as part of its Phase 2 development effort. The prototypes demonstrated functional sonar, communications, and mobility at deep depths.  The successful tests furthered DASH’s goals to apply advances in deep-ocean distributed sonar to help find and track quiet submarines.

  • DARPA shows smaller pixels, smaller thermal cameras for soldiers

    The U.S. military uses long-wave infrared (LWIR) cameras as thermal imagers to detect humans at night. These cameras are usually mounted on vehicles as they are too large to be carried by a single soldier and are too expensive for individual deployment. DARPA researchers, however, recently demonstrated a new five-micron pixel LWIR camera that could make this class of camera smaller and less expensive.

  • Interior Dept. releases progress report on U.S. Water Census

    The U.S. Interior Department issued released a report to Congress on the progress of the National Water Census. As competition for water grows — for irrigation of crops, for use by cities and communities, for energy production, and for the environment — the need for the National Water Census and related information and tools to aid water resource managers also grows. The Water Census will assist water and resource managers in understanding and quantifying water supply and demand, and will support more sustainable management of water resources.

  • Robot makes inspecting power lines simple, inexpensive

    Mechanical engineers invented a robot designed to scoot along utility lines, searching for damage and other problems that require repairs. Made of off-the-shelf electronics and plastic parts printed on an inexpensive 3D printer, the SkySweeper prototype could be scaled up for less than $1,000, making it significantly more economical than the two models of robots currently used to inspect power lines.

  • Scientists discover new materials to capture methane

    Scientists have discovered new materials to capture methane, the second highest concentration greenhouse gas emitted into the atmosphere. Unlike carbon dioxide, the largest emitted greenhouse gas, which can be captured both physically and chemically in a variety of solvents and porous solids, methane is completely non-polar and interacts very weakly with most materials.

  • First U.S. commercial enhanced geothermal system connected to the grid

    Enhanced geothermal system (EGS) projects capture power from intensely hot rocks, buried thousands of feet below the surface, which lack the permeability or fluid saturation found in naturally occurring geothermal systems. The Energy Department the other day announced the U.S. first commercial EGS project which supplies electricity to the grid.
