DARPA developing milimmter wave wireless communications to connect dismounted warfighters using UAVs and provide 100 Gb/s RF Backbone (100G)using High-altitude, long-endurance platforms.

October 13, 2018 Comm. & NW Comments Off on DARPA developing milimmter wave wireless communications to connect dismounted warfighters using UAVs and provide 100 Gb/s RF Backbone (100G)using High-altitude, long-endurance platforms.

Modern expeditionary military missions generate and exchange massive amounts of data that are used to produce situational awareness and guide decision-making. Much of the data must travel long distances along backbone communications networks composed of high-capacity links that connect command centers. Fiber optic cables provide the core backbone for …

NATO Conducts Locked Shields 2018: World’s Largest International Live-fire Cyber Defense Exercise to train security experts in Cyberwarfare

October 12, 2018 Cyber Comments Off on NATO Conducts Locked Shields 2018: World’s Largest International Live-fire Cyber Defense Exercise to train security experts in Cyberwarfare

The urgency behind NATO’s deepening interest in cyber defense is driven by the increasing sophistication of cyberthreats against member states, according to Brig. Gen. Christos Athanasiadis, assistant chief of staff cyber at SHAPE. NATO reported earlier this year that its infrastructure came under threat from 500 cyberattacks monthly in 2016.The …

RAND envision the world in 2040, analyze security challenges that will shape it and offer guidance to policymakers

October 11, 2018 Threats Comments Off on RAND envision the world in 2040, analyze security challenges that will shape it and offer guidance to policymakers

In coming decades, emerging technologies such as artificial intelligence and 3D printing will pose new risks to people, nations, and global security. At the same time, accelerating change will challenge policymakers’ capacity to adapt. Some of the questions that Michael Rich and his team are exploring in RAND under a …

Airborne or Spaceborne Synthetic aperture ladar (SAL) for centimeter-class resolution battlefield awareness

October 8, 2018 Photonics Comments Off on Airborne or Spaceborne Synthetic aperture ladar (SAL) for centimeter-class resolution battlefield awareness

Conventional optical imagers are limited in spatial resolution by the diffraction limit of the telescope aperture, as well as by the practical difficulties in increasing the telescope aperture. Synthetic aperture (SA) techniques can increase resolution beyond the diffraction limit of the receiving aperture. Just as synthetic aperture radar(SAR) working …

DARPA CHESS Program plans for human intellect teamed with autonomous technology for cyber defense

October 6, 2018 AI & IT, Cyber Comments Off on DARPA CHESS Program plans for human intellect teamed with autonomous technology for cyber defense

The Department of Defense (DoD) maintains information systems that depend on Commercial off-the-shelf (COTS) software, Government off-the-shelf (GOTS) software, and Free and opensource (FOSS) software. Securing this diverse technology base requires highly skilled hackers who reason about the functionality of software and identify novel vulnerabilities. This process requires hundreds or thousands of hours of …

October 5, 2018 Comm. & NW, Soldier Comments Off on Soldiers require Secure, low-intercept and low-detection communications and networking technologies for future battlefield

The vision for the future soldier is to be combat effective and also highly mobile, adaptive, networked, sustainable with total battle space situation awareness and information assurance. Therefore, he is equipped with night- vision goggles, radios, smartphones, GPS, infrared sights, a laptop as well as batteries to power them. All …

Auxetics, new materials for lightweight body and vehicle armor that strengthen when a bullet strikes

October 2, 2018 Army, Material Comments Off on Auxetics, new materials for lightweight body and vehicle armor that strengthen when a bullet strikes

What do a flea and an eagle have in common? They can store energy in their feet without having to continuously contract their muscles to then jump high or hold on to prey. Now scientists Now scientists at Queen Mary University of London and University of Cambridge have created materials that …

Vehicular Terrorism or ramming attacks require new technologies including directed energy weapons

September 30, 2018 Security, Weapons Comments Off on Vehicular Terrorism or ramming attacks require new technologies including directed energy weapons

Recently in Toronto a rental van was deliberately driven into a crowd of people, killing 10 and injuring 14. Police arrested and charged 25-year-old Alek Minassian in connection with the attack. Though this attack was later found to be caused by the driver’s psychiatric disorder. Deliberate vehicle-ramming incidents have also sometimes …

German scientists are using drones equipped with sensors to locate metals needed for wind turbines and solar panels

September 29, 2018 Material Comments Off on German scientists are using drones equipped with sensors to locate metals needed for wind turbines and solar panels

The sustainable growth of renewable energies depends on the availability of key materials, for example Lithium is the key limiting resource for most batteries – while rare earth metals, in particular “lanthanides” such as neodymium, are required for the magnets in wind turbine generators. Copper is the conductor of choice …

Nanomaterials based Biosensors chips can detect Biowarfare agents (BWAs) in real time and enhance soldiers performance

September 28, 2018 BioScience, Nanotech, Soldier Comments Off on Nanomaterials based Biosensors chips can detect Biowarfare agents (BWAs) in real time and enhance soldiers performance

The purpose of a biosensor is the detection of biologically-relevant targets such as proteins, DNA, pathogens, cells, bacteria, pollutants, hormones and enzymes. In most cases, their presence and/or concentration in samples such as blood, urine, saliva, sweat or tears can be an early indicator of disease, so that the sensor …
