• Improving high-speed rail ties against freezing, thawing conditions

    Research project is helping high-speed rail systems handle the stress of freezing and thawing weather conditions; the 3-year study looks at the freeze-thaw durability of concrete railroad ties; the research is essential to developing safe and durable high-speed rail systems

  • Researchers invent safe wireless vehicle charging technology

    Researchers have invented a safe, efficient technology wirelessly to charge electric vehicles using “remote magnetic gears” — a rotating base magnet driven by electricity from the grid, and a second located within the car — and successfully tested it on campus service vehicles

  • Smart camera to describe what it sees -- and reason about what it cannot see

    Army scouts are commonly tasked with covertly entering uncontrolled areas, setting up a temporary observation post, and then performing persistent surveillance for twenty-four hours or longer; what if instead of sending scouts on high-risk missions the military could deploy taskable smart cameras? A truly “smart” camera would be able to describe with words everything it sees and reason about what it cannot see

  • Making toilets out of waste plastic

    Washington Open Object Fabricators (WOOF) has won the 3D4D Challenge, and awarded a prize of $100,000 to help toward implementing the winning project – which will enable waste plastic to be used as filament for 3D printing machines, to create new products; the winning team plans to use the winning technology to address local issues in water and sanitation in Oaxaca, Mexico

  • Carbon-negative fuel at projected cost of less than $1.50 per gallon

    Cool Planet Energy Systems the other day announced a major breakthrough in the commercialization and affordability of biofuels from non-food biomass that can run in any vehicle on the road today; a successful field testing was conducted at Google Campus

  • The DARPA Robotics Challenge begins

    The DARPA Robotics Challenge (DRC) began yesterday, and DARPA wants to know whether you will be part of it; DARPA introduces teams for Tracks A and B, opens registration for Tracks C and D, and launches simulation software for download; the goal of the competition is to help advance robotic technology to the point where it can have a tangible impact on humanitarian assistance and disaster relief

  • Looming sequestration causes Navy to looking at future technology, fleet size

    Adm. Mark Ferguson, vice chief of naval operations, offered a revealing look at the potential future for the Navy if sequestration, or automatic defense cuts, goes into effect in January; without some sort of adjustment by Congress, currently the subject of discussion on Capitol Hill, the nearly 10 percent across-the-board Department of Defense budget cuts are slated to commence in 2013 and continue for ten years

  • Assessing bridge resilience

    Across the United States, more than 600,000 bridges link travelers to millions of roadway miles, forming a critical part of the nation’s infrastructure; because bridges are typically more vulnerable than roadways to damage caused by natural and man-made hazards, they are also of interest to DHS, which funds cutting-edge research in various aspects of structural integrity testing and blast-resistant structural design

  • Ideas from nature on how to convert solar into liquid fuel

    It has long been a dream of scientists to use solar energy to produce chemicals which could be stored and later used to create electricity or fuels; a recent scientific breakthrough is providing hope that this may soon be possible; the development would offer many benefits, including the ability to store chemicals until needed — current solar power technology has difficulties in this area

  • Faster data analysis on tactical handheld devices

    The Office of Naval Research (ONR) announced a new program to optimize tactical handheld technology for quick decision-making in the field; the Exchange of Actionable Information at the Tactical Edge (EAITE) program, designed to sift through data from multiple sources for faster analysis

  • Analyzing the sound of rain falling on a bridge reveals bridge’s health, stability

    Engineers have found that by listening to how a highway bridge sings in the rain, they can determine serious flaws in the structure; employing a method called impact-echo testing, engineers can diagnose the health of a bridge’s deck based on the acoustic footprint produced by a little bit of water

  • New app uses scattered public information to put together a digital footprint of individuals, organizations

    A new app application can collect scattered online clues to provide a picture of individuals or organizations; the application draws on public data sources in order to put together a graphical digital footprint

  • New military apparel repels chemical, biological agents

    Scientists are developing a new military uniform material that repels chemical and biological agents using a novel carbon nanotube fabric; the material will be designed to undergo a rapid transition from a breathable state to a protective state; the highly breathable membranes would have pores made of a few-nanometer-wide vertically aligned carbon nanotubes that are surface modified with a chemical warfare agent-responsive functional layer

  • Different technologies aim to replace dogs as explosives detectors

    Bomb-sniffing dogs are the best and most popular way for airport security quickly to detect anyone planning to bring explosives to an airport; scientists are trying to change that; Dr. Denis Spitzer and his colleagues, for example, are working on a sensor that will detect vapors of TNT and other explosives in very faint amounts; the device they are trying to create would replace dogs as the top bomb detecting method in the field

  • DARPA seeking tools for identifying hidden explosives at standoff

    The threat to U.S. soldiers from improvised explosive devices (IEDs) is as varied as the makers of IEDs are resourceful in how they design and conceal the explosives; interdisciplinary teams needed to develop proof-of-concept demonstrations of technology for identifying presence of embedded explosives in opaque, high-water-content substances
