• Funding extended for simulated nuclear reactor project

    Hard on the heels of a five-year funding renewal, modeling, and simulation (M&S) technology developed at Los Alamos National Laboratory as part of the Consortium for the Advanced Simulation of Light Water Reactors (CASL) will now be deployed to industry and academia under a new inter-institutional agreement for intellectual property. CASL is a U.S. Department of Energy’s Energy Innovation Hub established in 2010 to develop advanced M&S capabilities that serve as a virtual version of existing, operating nuclear reactors. As announced by DOE in January, the hub would receive up to $121.5 million over five years, subject to congressional appropriations.

  • Electric fields increase oil flow in the Keystone pipeline

    Traditionally, pipeline oil is heated over several miles in order to reduce the oil’s thickness (which is also known as viscosity), but this requires a large amount of energy and counter-productively increases turbulence within the flow. Researchers propose a more efficient way of improving flow rates by applying an electric field to the oil. The idea is to electrically align particles within the crude oil, which reduces viscosity and turbulence. The researchers have shown that a strong electric field applied to a section of the Keystone pipeline can smooth oil flow and yield significant pump energy savings.

  • New map outlines landslide risks in western Oregon

    Landslides are already a serious geologic hazard for western Oregon. During an earthquake, however, lateral ground forces can be as high as half the force of gravity. The Coast Range is of special concern because it will be the closest part of the state to the actual subduction zone earthquake, and will experience the greatest shaking and ground movement. New landslide maps have been developed that will help the Oregon Department of Transportation determine which coastal roads and bridges in Oregon are most likely to be usable following a major subduction zone earthquake that is expected in the future of the Pacific Northwest.

  • Security at U.S. chemical plants, and monitoring that security, still fall short

    Security experts, citing a critical Senate report, are warning that the effort by industry and the government to secure U.S. chemical facilities against terrorist attacks has so far been lackluster at best. The Senate report, sponsored by former Senator Tom Coburn (R-Oklahoma), found that after eight years and $595 million dollars spent on efforts to further chemical plant security, there had been only thirty-nine compliance inspections of the 4,011 national facilities at risk. In any event, the current chemical facility security policies apply only to a fraction of the facilities which produce, store, or transport toxic materials around the country. The experts hope that H. R. 4007, which reformed and renewed the 2007 Chemical Facility Anti-Terrorism Standards (CFATS), and which became Public Law No: 113-254 on 18 December 2014, will improve and accelerate the security work needed at U.S. chemical facilities.

  • IPCC sea-level rise scenarios insufficient for high-risk coastal areas management

    The sea-level rise scenarios of the Intergovernmental Panel on Climate Change (IPCC) do not necessarily provide the right information for high-risk coastal decision-making and management, according to new research. Researchers warn that the IPCC scenarios are often inappropriate or incomplete for the management of high-risk coastal areas as they exclude the potential for extreme sea-level rises. This missing information is also crucial for a number of policy processes, such as discussions by G7 countries to establish climate insurance policies and allocations of adaptation funding by the Green Climate Funds.

  • Cost of derailments of oil-carrying trains over the next two decades: $4.5 billion

    A 2014 CSX derailment led to roughly 30,000 gallons of Bakken crude oil spilling in and around the James River, West Virginia. Another CSX train derailed last week in the West Virginia town of Mount Carbon. The explosion that followed forced about 1,000 people to evacuate from their homes. The United States will likely experience more oil train derailments as long as Bakken crude oil is transported via rail from the Northern Plains’ Bakken region to U.S. refineries. Oil train accidents often lead to pipeline advocates pushing for more pipelines, but data from PHMSA shows that while oil trains have more frequent accidents, pipelines accidents cause much larger spills.

  • Obama’s cybersecurity initiative: a start but businesses – and individuals – need to do more

    The linchpin of President Obama’s recently launched cybersecurity initiative is to encourage the private sector to share information to better defend against cyberattacks. Yet U.S. companies have historically been wary of openly talking about their cybersecurity efforts with competitors and with government — for good reason. Many businesses fear that sharing threat-related information could expose them to liability and litigation, undermine shareholder or consumer confidence, or introduce the potential for leaks of proprietary information. For some companies, Edward Snowden’s revelations of sweeping government surveillance programs have reinforced the impulse to hold corporate cards close to the vest. Yet on the heels of a deluge of high-profile cyberattacks and breaches against numerous U.S. companies, we may finally have reached a tipping point, where potential harm to reputation and revenue now outweighs the downside of disclosure from a corporate perspective. Obama’s executive order is thus a spur to get the ball rolling but, frankly, there is a limit to what government alone can (and should) do in this area. Changes in attitudes and behaviors are needed across the board, right down to families and individuals.

  • A 2-year spike in sea level along NE North America

    Sea levels from New York to Newfoundland jumped up about four inches in 2009 and 2010 because ocean circulation changed, new research has found. Independent of any hurricanes or winter storms, the event – which stands out in its time extent as well as its spatial extent — caused flooding along the northeast coast of North America. Some of the sea level rise and the resulting flooding extended as far south as Cape Hatteras. The spike was the result of a change in the ocean’s Atlantic Meridional Overturning Circulation and also a change in part of the climate system known as the North Atlantic Oscillation. The researchers found that at the current rate that atmospheric carbon dioxide is increasing, such extreme events are likely to occur more frequently. The research also confirmed that, as others have reported, sea level has been gradually rising since the 1920s and that there is some year-to-year variation.

  • Ocean acidification threatens U.S. coastal communities

    Coastal communities in fifteen states that depend on the $1 billion shelled mollusk industry (primarily oysters and clams) are at long-term economic risk from the increasing threat of ocean acidification, a new report concludes. The Pacific Northwest has been the most frequently cited region with vulnerable shellfish populations, the authors say, but the report notes that newly identified areas of risk from acidification range from Maine to the Chesapeake Bay, to the bayous of Louisiana.

  • Concrete solutions to aging, structurally deficient bridges

    According to the Pennsylvania Department of Transportation (PennDOT), the state leads the nation in the number of bridges classified as “structurally deficient.” This is probably not a surprise to most residents who have done any driving throughout the commonwealth. The state’s more than 25,000 state-owned bridges are aging — their average age is over fifty years — and in need of repair. Penn State civil engineering faculty are researching methods for enhancing the maintenance and durability of civil infrastructure — including anything made of concrete, from bridges to roads to buildings.

  • Wireless sensors keep public infrastructure safe

    European researchers have developed a wireless sensor system to monitor the safety of large infrastructure such as bridges – but also historic monuments. The new system will potentially save lives as the structure ages, and it will reducing construction cost of new infrastructure.

  • Scanning technology detects early signs of potholes

    Researchers are developing smart scanning technology using existing cameras to detect the early signs of potholes and determine their severity. a computer vision algorithm, combined with 2D and 3D scanners on a pavement monitoring vehicle, can examine the road with accuracy at traffic speed during day or night. The system works by detecting different textures of the road to identify raveling and distinguishes it from shadows and blemishes such as tire marks, oil spills, and recent pothole repairs.

  • Bay of Bengal: Rising seas to force 13 million to evacuate to higher grounds

    Within the next thirty years, a substantial area — called the Sundarbans — in the Bay of Bengal will be underwater as a result of climate change-induced rising sea levels. The roughly thirteen million people living in the region, which consists of approximately 200 delta islands in India and Bangladesh, will be forced to abandon their homes, making their displacement the largest exodus in modern history. The migration of eight million Bangladeshis and five million Indians inland will create the largest group of “climate refugees,” challenging social, agricultural, logistical, and governmental structures.

  • More resilient mass transit to improve Chicago emergency evacuation system

    A group of Argonne Lab researchers will be studying methods and creating tools for building more resilient mass transit systems to evacuate major cities under a $2.9 million grant announced today by the U.S. Department of Transportation’s Federal Transit Administration. The project will bring together researchers from the Department of Energy’s Argonne National Laboratory with Chicago’s Pace Suburban Bus and Metra Commuter Rail Service to investigate ways to improve the detection, analysis, and response to emergencies, and how best to evacuate the city in a major emergency.

  • Coping with fracking-induced earthquakes

    A new study provides a case for increasing transparency and data collection to enable strategies for mitigating the effects of human-induced earthquakes caused by wastewater injection associated with oil and gas production in the United States. The study suggests that it is possible to reduce the hazard of induced seismicity through management of injection activities.
