Better explosives detection for soldiers, first responders in the field
From a chemical viewpoint, developing a detector for nitroaromatic compounds such as TNT is difficult because such compounds have a low vapor pressure, meaning their concentration in air at room temperature is around six parts per billion; MIT researchers develop cantilever sensors which use functional coatings to transduce detection of chemicals into a signal; the coating, usually a polymer, swells up when it reacts with the target analyte and deflects the cantilever

Israel's top 10 airport security technologies, II
No-one understands security as the Israelis do, and this is why some of the world’s best new innovative airport security technologies are being developed in Israel; since the foiled Christmas Day attempt on a Detroit-bound plane, airport authorities around the world are in a race to find novel solutions to fight terror, and the strategies and technical tactics Israel has adopted feature high on their lists

U.K. uses Hurt Locker robots to lure bright graduates from banking to defense
The U.K. defense experts believe too many graduates are being diverted into lucrative jobs in finance when they could be engineers or techies, helping the U.K. defense effort; the Ministry of Defense staged an event starring bomb-disposal and mine-clearing robots from the movie ‘The Hurt Locker” to highlight the exciting technology being used in defense

U.S. Congress anxious about shortages of rare earth materials
Rare earth materials are key to advanced technology — they are used in devices ranging from wind turbines to cell phones; trouble is, almost all of these materials come from China; Congress is worried that one day they could be subject to tight export controls by that country’s government

DHS moving forward on cell-all smartphone chemical detection technology
DHS wants to turn smartphones into chemical sensors; owners of smartphones would volunteer to have tiny chemical sensors embedded in their devices; millions of American could thus become roving chemical sensing nodes to alert authorities of terrorist — or accidental — chemical toxin release

Software turns laptops, PCs into earthquake early-warning system
Harnessing the power of accelerometers — tiny devices that detect movement, allowing, for example, iPhones to flip from vertical to horizontal and Wii devices to function as tennis rackets — and embedding them in laptops and PCs would create a local, regional, or even global network of “quake catchers” who would use their computers to map tremors

U.K. Home Offices praises University of Reading CCTV research
The Computational Vision Group at the University of Reading has developed computer systems which emulate human vision and is currently working on improving the effectiveness of CCTV for safety, security, and threat assessment purposes; the systems will be used in crowd image analysis, spotting unattended luggage, and detecting threats to aviation both on the ground and in the air

Tiny, sensitive nano oscillator instantly detects pathogens in air or water
Extraordinarily tiny sensors that can instantly recognize harmful substances in air or water; the device is just 200 nanometers thick and a few microns long with an oscillating cantilever hanging off one end; the cantilever is like a diving board that resonates at distinct frequencies

Flying ambulance: UAV will extract wounded soldiers from the battlefield
There is one more mission being added to the ever-expanding list of operational, intelligence, surveillance, law-enforcement, first response, and disaster recovery missions assigned to UAVs: evacuating critically injured casualties directly from the battlefield to the hospital

Underground intelligence satellite navigation will work off lightning strikes
The U.S. ubiquitous eye-in-the-sky satellites have driven more and more people and things of interest to disappear underground (just think Iran’s nuclear weapons program); deep tunnel complex shields an organization from the prying eyes of satellites, and it is also good protection against a sudden bombing raid; the U.S. military wants to be able to peek and conduct operations underground

World's first practical jetpack commercially available for $75,000
Kiwi company Martin Aircraft is offering the world’s first commercial jetpacks; the machine is expected to revolutionize the military and be taken up by emergency services; the jetpack travels for about 30 minutes on a five-gallon tank of premium gasoline, has top speeds of 60 mph, and reaches heights of 2,400 meters (about 1.5 miles)

New surveillance camera offers panoramic view, zoom-in capabilities
Not unlike the surveillance cameras that tracked Will Smith’s every move in the movie “Enemy of the State,” Adaptive Imaging Technologies’ “panoramic telescope” may yet revolutionize the field of surveillance: the camera can, at the same time, monitor a panoramic field of view and zoom in on any spot in real time with exceptional clarity

Tiny sensor "listens" to gunshots to identify source of fire and type of weapon
The sensor, developed by a Dutch company, is smaller than the head of a match, made of two 200-nanometer-thick, 10-micrometer-wide platinum strips that are heated to 200 degrees Celsius; the sensor does not truly “listen” to sounds; rather, it senses air particles that flow past the platinum strips and cool them unevenly

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.
