• Ways to stop a rogue drone

    The mounting threat of drone users not following aviation regulation or committing crimes means police need effective ways to stop and capture rogue devices. One of the key challenges for any anti-drone counter-measure is that the typical small size of most drones makes them difficult to detect and target. One novel and widely reported idea being explored by the Dutch National Police is the training of bald eagles to down drones. A perfect solution has yet to be found, but interest and investment in drone countermeasures is increasing, giving authorities a growing number of options for tackling rogue drones.

  • Munitions that go further, much faster

    Researchers discovered a new way to get more energy out of energetic materials containing aluminum, common in battlefield systems, by igniting aluminum micron powders coated with graphene oxide. The discovery coincides with the one of the U.S. Army’s modernization priorities: Long Range Precision Fires. This research could lead to enhanced energetic performance of metal powders as propellant/explosive ingredients in Army’s munitions.

  • Alternatives to open burning, open detonation of conventional waste munitions

    Most of the alternative technologies to open burning and open detonation (OB/OD) of conventional munitions designated for disposal are mature, including contained burn and contained detonation chambers with pollution control equipment, and many are permitted to replace OB/OD of waste munitions, says a new report by the National Academies of Sciences.

  • Developing concepts for escape respirator

    DHS S&T announced the Escape Respirator Challenge, a $250,000 prize competition that seeks new concepts for an escape respirator solution. This challenge invites the innovation community to submit relevant, useable, effective, and feasible concepts that protects the user against aerosolized chemical, biological, and radiological (CBR) hazards and provides oxygen.

  • Fault displacement “fingerprints” helps forecast magnitude of rupture

    Machine-learning research helps detect seismic signals accurately, allowing them to predict the Cascadia fault’s slow slippage, a type of failure observed to precede large earthquakes in other subduction zones.

  • Airport security screening without queues

    Researchers have invented a device that could be developed into ultra-sensitive cameras for security screening which would not require people to queue at airports. Other applications could include smaller and safer sensors for driverless vehicles.

  • VitalTag to give vital information in mass casualty incidents

    When mass casualty incidents occur — shootings, earthquakes, multiple car pile ups — first responders can easily be overwhelmed by the sheer number of victims. When every second counts, monitoring all the victims in a chaotic situation can be difficult. Researchers developed a stick-on sensor that measures and tracks a patient’s vital signs to help first responders quickly triage, treat and transport the injured.

  • Foldable drone flies through narrow passages in rescue missions

    Researchers have developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

  • Bolstering cyber-physical systems security

    Researchers have been awarded a grant of nearly $1 million to develop stronger safeguards for a wide array of complex systems that rely on computers – from public water supply systems and electric grids to chemical plants and self-driving vehicles. Increasingly, these cyber-physical systems, or CPS, are threatened by both physical and cyberattacks.

  • Friendly electromagnetic pulse improves survival for electronics

    An electromagnetic pulse, or EMP, emitted by a nuclear weapon exploded high above the United States could disable the electronic circuits of many devices vital to military defense and modern living. These could include complicated weapon systems as well as phones, laptops, credit cards and car computers. Also, in trouble might be home appliances, gas station pumps and bank accounts. Military equipment – and some civilian equipment, too — are designed to be immune to various levels of EMP, and the validity of these designs has been tested and improved by a “friendly” EMP generator installed in a recently renovated facility at Sandia National Laboratories.

  • DHS S&T awards $1.14 million for improving cyber data privacy

    DHS S&T has awarded a total of $1,149,900 across two organizations to develop new research and development (R&D) capabilities to enhance the management of privacy threats and vulnerabilities.

  • Inexpensive super-absorbent material offers solution for ocean oil spills

    A super-absorbent material developed by Penn State scientists could dramatically reduce the environmental impact of oil spills on oceans and allow recovered oil to be refined normally. The synthetic material, called i-Petrogel, absorbs more than 40 times its weight in crude oil, and effectively stops the oil from spreading after a spill, according to the researchers.

  • New cryptography must be developed and deployed now, even if quantum threats are a decade away

    Given the current state of quantum computing and the significant challenges that still need to be overcome, it is highly unlikely that a quantum computer that can compromise public-key cryptography – a basis for the security of most of today’s computers and networks – will be built within the next decade, says a new report by the National Academies of Sciences. However, because replacing an established internet protocol generally takes over a decade, work to develop and deploy algorithms that are resilient against an attack by a quantum computer is critical now.

  • Machine learning masters the fingerprint to fool biometric systems

    Fingerprint authentication systems are a widely trusted, ubiquitous form of biometric authentication, deployed on billions of smartphones and other devices worldwide. Yet a new study reveals a surprising level of vulnerability in these systems.

  • Is anybody out there?

    The question of whether we’re alone in the universe has haunted humankind for thousands of years, and it’s one astronomer Jill Tarter has tried to answer for much of her life. Tarter, chair emeritus of the Center for SETI Research, worked as a project scientist for NASA’s SETI program, which aimed to detect transmissions from alien intelligence.
