• Mobile app helps first responders choose the right biodetection technology

    First responders have downloaded more than 10,000 copies of a guide to commercially available, hand-portable biodetection technologies created to help them determine what they might be up against in the field. Since many first responders do not always have immediate access to a computer, a mobile version of the guide is now available for cell phones and tablets. An updated version of the guide has just been released to help response organizations make informed decisions when procuring the right technology for their particular needs and circumstances.

  • Smart grenade seeks, finds enemy hiding behind barriers, walls

    The Small Arms Grenade Munition (SAGM) round — a 40mm counter-defilade, air-bursting grenade designed for both the M203 and M320 launchers — will undergo evaluation in July 2015. The SAGM allows a soldier to target an enemy who is protected behind a barrier and have the munition explode, in the air, above the target. The SAGM does not require the soldier to conduct any kind of pre-fire programming sequence. The soldier aims the weapon and fires, and the round detects where a wall is and then explodes, in the air, after passing the wall. The SAGM round has been under development since January 2012.

  • Reducing uncertainty in designing complex military systems

    Uncertainty is sometimes unavoidable, but in the world of scientific computing and engineering, at least, what is worse than uncertainty is being uncertain about how uncertain one is. Understanding with confidence the level of uncertainty in computational models used for designing complex military systems can be enormously beneficial, reducing costs and development times. DARPA program seeks novel mathematical research for quantifying and predicting uncertainty in design models as alternative to costly and repetitive testing.

  • Nanomaterial proves to be a better flame retardant than chemical alternative

    In a face-off between two promising flame retardants, the challenger — a nanomaterial that maintains a positive façade while sheltering a negative interior — outperformed its chemical antithesis. This material already is a leading candidate for environmentally friendly fire-resistant coatings on furniture foam.

  • Improved protective suit for Ebola caregivers

    An advanced protective suit for health care workers who treat Ebola patients, devised by a Johns Hopkins University team, is one of the first five awardees in a federal funding contest aimed at quickly devising new tools to combat the deadly disease. The JHU prototype is designed to do a better job than current garments in keeping health care workers from coming in contact with Ebola patients’ contagious body fluids, both during treatment and while removing a soiled suit. In addition, it is expected to keep the wearer cooler — an important benefit in hot, humid regions such as West Africa.

  • Helping first-response robots operate for longer periods

    Through a project supported by the Defense Advanced Research Projects Agency (DARPA), Sandia Lab is developing technology which will dramatically improve the endurance of legged robots, helping them operate for long periods while performing the types of locomotion most relevant to disaster response scenarios. One of Sandia’s new robots which showcases this technology will be demonstrated at an exposition to be held in conjunction with the DARPA Robotics Challenge Finals next June.

  • Helicopter steering innovation could herald new era for aerial transport

    For decades, flying cars have featured in our visions of what futuristic cities might look like. Now EU-funded researchers with the MYCOPTER project have developed a steering system that makes helicopters as easy to control as cars. While having your own personal aerial vehicle (PAV) may still be some way off, the success of the project opens up the possibility that one day flying vehicles could indeed be an integral part of the urban transportation network.

  • A first: U.S. Navy shipboard laser operates in Persian Gulf

    The U.S. Navy announced that a laser weapon system (LaWS) — a cutting-edge weapon that brings significant new capabilities to America’s Sailors and Marines — was for the first time successfully deployed and operated aboard a naval vessel in the Persian Gulf. The operational demonstrations, which took place from September to November aboard USS Ponce (AFSB[I] 15), were historic not only because they showed a laser weapon working aboard a deployed U.S. Navy ship, but also because LaWS operated seamlessly with existing ship defense systems. During the tests, LaWS hit targets mounted aboard a speeding oncoming small boat, shot a Scan Eagle unmanned aerial vehicle (UAV) out of the sky, and destroyed other moving targets at sea.

  • Bionic bra one step closer

    A Bionic Bra which automatically tightens in response to breast movement is one step closer to reality with the development of a new prototype. The development of the bra is the result of findings by researchers that without the right breast support, the movement of women’s breasts during demanding physical activity – in sports, the military, first response, and more – may cause long-term damage, including numbness in the fingers caused by compression of nerves on the shoulders, as well as neck and back pain. “Unfortunately, the most supportive sports bras tend to be the most uncomfortable to wear.” Making matters worse, “research has found that 85 percent of women are wearing bras that do not fit or support their breasts correctly,” one of the researchers said.

  • Smaller lidars could be mounted on UAVs for underwater scans

    Bathymetric lidars — devices which employ powerful lasers to scan beneath the water’s surface — are used today primarily to map coastal waters. At nearly 600 pounds, the systems are large and heavy, and they require costly, piloted aircraft to carry them. Georgia Tech Research Institute (GTRI) researchers have designed a new approach that could lead to bathymetric lidars that are much smaller and more efficient than the current full-size systems. The new technology would let modest-sized unmanned aerial vehicles (UAVs) carry bathymetric lidars, lowering costs substantially. These advanced capabilities could support a range of military uses such as anti-mine and anti-submarine intelligence and nautical charting, as well as civilian mapping tasks. In addition, the new lidar could probe forested areas to detect objects under thick canopies.

  • Mobile biometric device expedites identity matching

    The Stockton (California) Police Department (SPD) has been quietly testing a state-of-the-art Mobile Biometric Device (MBD) technology for the past four years. Designed quickly to scan fingerprints, irises, and other biological information while officers and evidence technicians are on the field, MBDs can communicate with remote fingerprint databases and confirm matches in as little as three minutes.

  • Los Alamos National Lab: Deploying 100 supercomputers over 60 years in support of national security

    From the 1952 MANIAC to Bonanza deployed just this month, Los Alamos National Laboratory has deployed 100 supercomputers in the last sixty years — a showcase of high-performance computing history. The Los Alamos computers deployed along the way include the MANIAC II, which started its nearly 20-year service life with over 5,000 vacuum tubes, all of which were replaced over time with circuit boards. Other deployed systems include Stretch, a technological stretch built in collaboration between Los Alamos and IBM, Serial Number 1 of the iconic Cray-1, and a Thinking Machines CM-5, with its lightning bolt footprint and fat-tree interconnect. By 2008 there came Roadrunner, the world’s first petaflop supercomputer.

  • New technology increases awareness of landslide risks

    Engineers have created a new way to use lidar technology to identify and classify landslides on a landscape scale, which may revolutionize the understanding of landslides in the United States and reveal them to be far more common and hazardous than often understood. The new, non-subjective technology can analyze and classify the landslide risk in an area of fifty or more square miles in about thirty minutes — a task that previously might have taken an expert several weeks to months. It can also identify risks common to a broad area rather than just an individual site.

  • Transforming planes into flying aircraft carriers

    Military air operations typically rely on large, manned, robust aircraft, but such missions put these expensive assets — and their pilots — at risk. While small unmanned aircraft systems (UAS) can reduce or eliminate such risks, they lack the speed, range, and endurance of larger aircraft. These complementary traits suggest potential benefits in a blended approach — one in which larger aircraft would carry, launch, and recover multiple small UAS. A flying carrier would allow the United States to use of drones in areas where the United States has no access to nearby airfields, but recovering a drone in mid-air remains a daunting technical challenge.

  • New acoustic sensor for chemical, biological detection

    Testing for ovarian cancer or the presence of a particular chemical could be almost as simple as distinguishing an F sharp from a B flat, thanks to a new microscopic acoustic device that has been dramatically improved by scientists at the Argonne National Laboratory. The device, known as a surface acoustic wave (SAW) sensor, detects frequency changes in waves that propagate through its crystalline structure. This makes it ideal for detecting the presence of chemicals or biomarkers present in a liquid or gas.
