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

U.S. Navy tests the second of two railgun prototypes
The EM Railgun launcher is a long-range naval weapon that fires projectiles using electricity instead of traditional gun propellants such as explosive chemicals; magnetic fields created by high electrical currents accelerate a sliding metal conductor, or armature, between two rails to launch projectiles at 4,500-5,600 mph; the Office of Naval Research’s Electromagnetic (EM) Railgun program is evaluating the second of two industry railgun prototype launchers at a facility in Dahlgren, Virginia

Boarding gate with built-in explosives detection speeds up airport security checks
Japanese researchers have developed a boarding gate with built-in explosives detection equipment; the gate collects minute particles which have affixed themselves to IC cards or portable devices used as boarding passes, and can detect within one or two seconds the presence of explosive compounds using internalized equipment; the developers say the gate allows the inspection of 1,200 passengers per hour

Autonomous Vehicle Technology Vulnerable to Road Object Spoofing and Vanishing Attacks
Researchers have demonstrated the potentially hazardous vulnerabilities associated with the technology called LiDAR, or Light Detection and Ranging, many autonomous vehicles use to navigate streets, roads and highways. The researchers have shown how to use lasers to fool LiDAR into “seeing” objects that are not present and missing those that are – deficiencies that can cause unwarranted and unsafe braking or collisions.
Tantalizing Method to Study Cyberdeterrence
Tantalus is unlike most war games because it is experimental instead of experiential — the immersive game differs by overlapping scientific rigor and quantitative assessment methods with the experimental sciences, and experimental war gaming provides insightful data for real-world cyberattacks.
Prototype Self-Service Screening System Unveiled
TSA and DHS S&T unveiled a prototype checkpoint technology, the self-service screening system, at Harry Reid International Airport (LAS) in Las Vegas, NV. The aim is to provide a near self-sufficient passenger screening process while enabling passengers to directly receive on-person alarm information and allow for the passenger self-resolution of those alarms.
Falling Space Debris: How High Is the Risk I'll Get Hit?
An International Space Station battery fell back to Earth and, luckily, splashed down harmlessly in the Atlantic. Should we have worried? Space debris reenters our atmosphere every week.
Testing Cutting-Edge Counter-Drone Technology
Drones have many positive applications, bad actors can use them for nefarious purposes. Two recent field demonstrations brought government, academia, and industry together to evaluate innovative counter-unmanned aircraft systems.
Strengthening the Grid’s ‘Backbone’ with Hydropower
Argonne-led studies investigate how hydropower could help add more clean energy to the grid, how it generates value as grids add more renewable energy, and how liner technology can improve hydropower efficiency.
The Tech Apocalypse Panic is Driven by AI Boosters, Military Tacticians, and Movies
From popular films like a War Games or The Terminator to a U.S. State Department-commissioned report on the security risk of weaponized AI, there has been a tremendous amount of hand wringing and nervousness about how so-called artificial intelligence might end up destroying the world. There is one easy way to avoid a lot of this and prevent a self-inflicted doomsday: don’t give computers the capability to launch devastating weapons.
