• Navy drone lands on ship without human assistance

    A U.S. Navyexperimental drone has executed several landings on the USS George H.W. Bush, marking an advance in robotic aviation. The drone calculated, without human assistance, how fast to approach the ship, when to put its wheels down, and when to hit the brakes.

  • U.S. Emergency Alerting System (EAS) vulnerable to hacking

    The U.S. Emergency Alerting System (EAS) is designed to allow for quick alerts during an emergency. Researchers uncovered vulnerabilities in the digital alerting systems, vulnerabilities which allow an attacker remotely to log in over the Internet and manipulate any system function. The attacker could disrupt a TV or radio station’s ability to transmit and could disseminate false emergency information.

  • Russia: Syria rebels used sarin gas

    Vitaly Churkin, Russia’s UN ambassador, announced at a UN news conference Tuesday that scientific analysis by Russian labs of a suspected chemical weapons attack in Syria on 19 March concluded the attack probably had been carried out by rebels using sarin nerve gas of “cottage industry” quality. He said the gas was delivered by a crudely made missile.

  • Advancements in technology making it easier to fight wildfires

    Following the Arizona wildfire disaster, many have been suggesting that new regulations are needed to control the spread of wildfires. Experts say that advancements in technology may well offer a more effective approach to saving lives and making it easier for firefighters to control wild blazes.

  • Firefighting experts calling for easing environmental restrictions on prescribed burns

    In the aftermath of the Arizona wildfire which killed nineteen firefighters in Yarnell, Arizona, there are growing calls for easing environmental restrictions which currently limit brush clearing and prescribed burns. It typically costs $5 per acre to conduct a prescribed burn in the wilderness, and about $50 per acre near residential areas. Thinning an area with chain saws and other equipment can cost around $500 per acre. These figures are small when compared to the $1,200 per acre cost of fighting the wildfire in Arizona.

  • CBP drones may be armed with non-lethal weapons

    Customs and Border Protection (CBP) currently has eight Predator drones used on the northern and southern borders, and two more drones watching the Caribbean. The drones are equipped with high-tech cameras. Critics say drones are not an efficient way to monitor the border, and that they lead to few arrests and seizures. Other critics are worry about something else: a recent CBP report show that the agency is considering arming these drones with “expendables or non-lethal weapons designed to immobilize [targets of interest].”

  • Highly portable X-ray imaging system developed

    Los Alamos National Laboratory and Tribogenics have developed the MiniMAX (Miniature, Mobile, Agile, X-ray) camera to provide real-time inspection of sealed containers and facilities.MiniMAX is an alternative to the large, expensive, and fixed facilities presently required for security inspections using X-ray imaging. The complete MiniMAX portable radiography system weighs less than five pounds.

  • Gauging how residents in storm-prone regions react in the event of an imminent storm

    StormView software program gauges how residents of hurricane-prone regions react to warnings and prepare for storms. The program is designed to be as realistic as possible in order accurately to assess how people would react in the event of an imminent storm.

  • Obama says Arizona wildfire deaths open up broader questions

    President Barack Obama said on Monday that several states need to reassess their wildfire management policies in the aftermath of the death of the nineteen firefighters who died battling an Arizona blaze.

  • The differences between impulsive and predatory murderers

    A pioneering study finds distinct differences between two types of murderers: impulsive murderers and predatory, or premeditated, murderers. Impulsive murderers were much more mentally impaired, particularly cognitively impaired, while predatory or premeditated murderers exhibit deeper psychiatric disorders.

  • Remote-controlled cockroaches to help in search-and-rescue missions

    Researchers are using video game technology to remotely control cockroaches on autopilot, with a computer steering the cockroach through a controlled environment. The researchers are using the technology to track how roaches respond to the remote control, with the goal of developing ways that roaches on autopilot can be used to map dynamic environments — such as collapsed buildings.

  • Robots to assist humans in mitigating, recovering from future natural and man-made disasters

    The goal of DARPA Robotics Challenge (DRC) is spur development of advanced robots that can assist humans in mitigating and recovering from future natural and man-made disasters. Seven teams will receive DARPA support to compete with an ATLAS Robot in 2013.

  • New firefighter breathing equipment test goes into effect 1 September

    As of 1 September 2013, standard firefighter breathing equipment cannot be certified to National Fire Protection Association (NFPA) standards unless the facepiece lenses pass a new rigorous test developed by the National Institute of Standards and Technology (NIST).

  • Improved water purification technology reduces logistics burden

    The logistics burden of supplying water to deployed troops is comparable to that of fuel and the economic cost is high. The Department of Defense (DoD) currently relies on a number of water desalination systems to produce clean water from local sources, but all of these systems have size, weight, and power (SWaP) constraints that affect their suitability for some missions. DARPA initiated the Materials with Novel Transport Properties (MANTRA) program to improve water desalination technologies and reduce their SWaP requirements.

  • Gun-possession arrests reduce subsequent crimes involving firearms

    Gun possession arrests made by a concentrated, proactive patrol unit in the Houston Police Department were linked to significant reductions in subsequent crimes involving firearms, a study finds.
