Innovative decontamination cloth reaches market
A new decontamination cloth, developed for use by soldiers and first responders, is now available in several forms — as preshaped mitts for personal wipedowns if someone is exposed to toxins or chemicals, individual wipe cloths and pads, and in rolls perforated to produces 12-inch by 12-inch sheets, like paper towels in a kitchen

Vallon showcases innovative mine detector
German company Vallon unveiled its latest mine detection system; one of its advantages is that it can detect mines made with no metal parts (the device can detect metal-free particles at a depth of 40 cm, and metal objects at greater depths); the UN is already deploying the device in mine-clearance operations in thirty countries

Day of invisibility cloak nears
In physics, the Doppler Effect describes the change in frequency of light or sound waves whenever there is a relative movement between an observer and a wave’s source; thus, when an object and an observer move closer together, light frequency increases from red wavelengths to blue ones; when they move further apart, light frequency decreases from blue to red; researchers have for the first time ever demonstrated a reversal of the optical Doppler Effect — a promising sign for the future development of science fiction-inspired technology such as invisibility cloaks; this technology, which has already been demonstrated on a micro-scale by U.S. researchers, may be closer to becoming a reality than most people think

Invisibility cloaks are hiding around the corner
In 1897 H. G. Wells created a fictional scientist who became invisible by changing his refractive index to that of air, so that his body could not absorb or reflect light; more recently, Harry Potter disappeared from sight after wrapping himself in a cloak spun from the pelts of magical herbivores; now, a Michigan Technology University researcher has found ways to use magnetic resonance to capture rays of visible light and route them around objects, rendering those objects invisible to the human eye

Engineers use Xbox Kinect to find earthquake survivors
A team of engineers at the University of Warwick in the United Kingdom has been working to develop a robot capable of entering unstable buildings and searching for survivors, such as the 200 purportedly missing after the 6.3 magnitude earthquake in Christchurch, New Zealand; until now, technology has relied on expensive laser-based equipment, but Warwick’s team has reconfigured Microsoft’s Xbox Kinect to identify places in which survivors may be

Engineering competition features Blue Tooth-capable trebuchet
During the first Storm the Citadel Trebuchet Competition in Charleston over the weekend, Google employees combined Android cell phones, a computer the size of a credit card, and a Blue Tooth receiver to trigger a medieval weapon used in the twelfth century to destroy enemy fortifications

Wine testing technology to scan for liquids at airports
Scanner technology originally developed at the University of California, Davis, to test wine in the bottle is being re-engineered to tell shampoo from explosives at airports; this means travelers could be able to carry soda cans or full-size tubes of toothpaste through security and onto jetliners in the not-too-distant future

Acoustic gunfire detection devices heading to the field
Technological developments may one day create artificial soldiers, but until they come along, the United States and other countries will continue to rely on human soldiers; the militaries thus want to preserve as many of their soldier’s lives as possible; to that end, Shoulder-Worn Acoustic Targeting System (SWATS), which helps Marines zero in on enemy sniper fire, is a godsend to the United States; asymmetric warfare favors the forces that can strike and runaway unharmed, but with plentiful acoustic sensors in the field it will be that much harder for snipers to ambush U.S. soldiers and live to escape

To boldly go -- but at a leisurely pace
In 1961 President John Kennedy committed the United States to land a man on the moon “before this decade is out”; DARPA new space project has a more lackadaisical time table: building an interstellar starship capable of carrying people to other star systems than our own by the year 2100AD

Aussie "thinking cap" makes brain waves
Scientists in Australia say they are encouraged by initial results of a revolutionary “thinking cap” that aims to promote creativity by passing low levels of electricity through the brain; the device works by suppressing the left side of the brain, associated with knowledge, and stimulating the right side, linked to creativity.

A fast, simple test for detecting cholera
The new detection method uses specially prepared nanoparticles of iron oxide, each barely 1/50,000th the width of a single human hair, coated with a type of sugar called dextran; to achieve this, the scientists looked for specific characteristics of the cholera toxin receptor (GM1) found on cells’ surface in the victim’s gut, and then they introduced these features to their nanoparticles; when the magnetic nanoparticles are added to water, blood, or other fluids to be tested, the cholera toxin binds to the nanoparticles in a way that can be easily detected by instruments

iPhone app helps police "see" through walls
Law enforcement officials are using SafetyNet Mobile, a powerful new iPhone app, to fight crime; the app allows police officers to quickly access all emergency dispatch information including maps, warnings, hazard information, and other critical data; to access the emergency dispatch database, the officer simply points the iPhone or iPad’s camera at a location; this technology allows police to “see” behind doors or walls by alerting them to any potential dangers inside; the app installs on any iPhone or iPad; SafetyNet Mobile has been successfully tested by three police departments in California and is currently being rolled out

Beaming rockets into space
Space launches have evoked the same image for decades: bright orange flames exploding beneath a rocket as it lifts, hovers, and takes off into the sky; an alternative propulsion system proposed by some researchers could change that vision; instead of explosive chemical reactions on-board a rocket, the new concept, called beamed thermal propulsion, involves propelling a rocket by shining laser light or microwaves at it from the ground; with the beam shining on the vehicle continually, it would take eight to ten minutes for a laser to put a craft into orbit, while microwaves would do the trick in three to four minutes

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.

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.
