  • Ammonium nitrate fertilizers are inherently risky, but the benefits are many

    The deadly explosion has brought the $10 billion U.S. fertilizer industry to the attention of the mainstream media, but the risks inherent in fertilizer production and storage are not a secret to people close to the industry. Ammonium nitrate may be dangerous, but its benefits cannot be ignored.

  • Reinvestment in U.S. water infrastructure should be a top national priority

    The U.S. water infrastructure is often called the “invisible infrastructure” – a vast, largely invisible network of pipes and tunnels — nearly 1.4 million miles span across the United States, which is eight times the length of the U.S. highway system. Much of the U.S. infrastructure was built more than a century ago, and currently around 10 percent of these systems are at the end of their service life. If not addressed by 2020, this number could rise to 44 percent. A summit meeting of the U.S. water community calls on Congress to make water infrastructure a top national priority.

  • 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.

  • White House threatens to veto House cybersecurity bill

    The White House on Tuesday threatened to veto the cybersecurity bill drafted by the House of Representatives. The house is expected to vote on the bill later this week. The cybersecurity bill died in the Senate last August after the White House said it would veto the bill.

  • 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.

  • Energy Department to invest in used nuclear fuel storage research

    As part of its efforts to develop an effective strategy for the safe and secure storage and management of used nuclear fuel, the Energy Department the other day announced a new dry storage research and development project. In the Energy Department’s budget request presented last week, the department requested $60 million for nuclear waste research and development.

  • 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.

  • Former NRC chairman: all 104 U.S. nuclear reactors suffer from “irreparable” safety issues

    According to former U.S. Nuclear Regulatory Commission (NRC) chairman Gregory Jaczko, all 104 nuclear reactors in the United States currently have irreparable safety issues and should be shut down and replaced. Jaczko was the NRC chairman from 2009 through 2012.

  • Critics: Fukushima-influenced U.S. nuclear accident response procedures are flawed

    The U.S. government is using the Fukushima nuclear disaster in Japan two years ago as a model for rewriting its plans on how to respond to radiation contamination — emphasizing long-term cleanup and return of residents to affected areas instead of emergency response. Critics say this is a mistake.

  • Larger fire-fighting crews save lives, limit damage in high-rise fires

    Between 2005 and 2009 there were, on average, 15,700 high-rise structure fires annually in the United States. Average annual losses totaled 53 civilian deaths, 546 civilian injuries, and $235 million in property damage. When responding to fires in high-rise buildings, firefighting crews of five or six members — instead of three or four — are significantly faster in putting out fires and completing search-and-rescue operations, concludes a major new study.

  • Aging national power grid leaves U.S. vulnerable to storm-related outages

    In parts of the United States where the grid system is “out in the open” and exposed to the elements — especially in our older cities — the risk increases for widespread power outages as a result of weather-related events, leading to lengthy, costly repairs.

  • Direct CO2 removal could lower costs of climate mitigation

    Two broad strategies are typically offered to protect infrastructure from the consequences of climate change: reducing to emissions of CO2 into the atmosphere by using less fossil fuels, and mitigation (building sea walls, dams, and levees; changing building codes, etc.). Both approaches are costly. Scientists suggest that directly removing CO2 from the air could alter the costs of climate change mitigation. It could allow prolonging greenhouse-gas emissions from sectors like transport which are difficult, and thus expensive, to turn away from using fossil fuels.

  • House panel approves CISPA, angering privacy advocates

    The U.S. House Intelligence Committee passed a cybersecurity measure by an overwhelming vote, a measure which privacy advocates dislike because, they argue, it does not protect the personal information of citizens.

  • DHS, international tech-crime investigative body, partners on cybersecurity

    The High Technology Crime Investigation Association (HTCIA) said it would team up with DHS Stop. Think. Connect. Campaign’s National Network. The partnership will promote awareness of cyber security to industry, university, and government organizations nationwide.
