USAF looking to emulate fruit-flies for killer insect swarm drones
The U.S. Air Force is studying how fruit flies maneuver within a heavily instrumented “simulation tunnel” in order to develop tiny, potentially lethal insect-sized flying robots; tiny military swarm droids could scatter across towns or cities to locate or spy on persons of interest to the U.S. military; they might even be able to land on the back of someone’s neck and blow his head off using some kind of tiny warhead

New strategy for UAVs: emulate the soaring approach of peregrine falcons
UAVs could fly for longer using less power if they copied the counter-intuitive flying patterns of peregrine falcons, say researchers; falcons, instead of spiraling in one direction to stay with a single thermal, constantly change the direction of their spirals

Color-changing "blast badge" detects exposure to explosive shock waves
Researchers develop a color-changing patch that could be worn on soldiers’ helmets and uniforms to indicate the strength of exposure to blasts from explosives in the field; blast-induced traumatic brain injury is the “signature wound” of the current wars in Iraq and Afghanistan; with no objective information of relative blast exposure, soldiers with brain injury may not receive appropriate medical care and are at risk of being returned to the battlefield too soon

Police radar can identify suicide bombers
The radar guns police use to spot speeding motorists fire microwave pulses at a car and measures the Doppler shift of the reflected signal to calculate its velocity; researchers found that the strength and polarization of the reflected signal — the “radar cross section” — can also measure the reflected signal created by the most common arrangements of looped wiring typically used by suicide bombers

Game-changing rifle arrives in Afghanistan
A new smart rifle can be programmed so that its 25-mm. ammunition does not explode on impact; instead, it can be set to detonate either in front of or behind a target, meaning it literally will go through a wall before it explodes and kills the enemy; the Army says that enemy soldier can run, but they can no longer hide

DARPA looking for a game interface to end all interfaces
A soldier in the field has his or her hands and voice fully taken up managing their weapons, sensors, and communications; DARPA wants to help: the Pentagon’s push-the-envelope research unit asks for idea on how to develop an interface which would allow soldiers to run, leap, or otherwise navigate about virtually without needing to do so physically

DARPA: Break-up of hypersonic airplane/missile no big deal
DARPA first test of its hypersonic airplane/missile — Falcon HTV-2 — failed after the prototype broke up on re-entering the atmosphere; after investigating the causes of the accident, the agency said it is ready for another test; the HTV-2 unmanned test vehicle had no propulsion of its own, being intended rather to try out new airframe and control technologies for use in hypersonic weapons or aircraft of the future

Blood camera detects invisible stains at crime scenes
At present, blood stains in a crime scene are detected using the chemical luminol; luminol is toxic, however, and can dilute blood samples to a level at which DNA is difficult to recover; it can also smear blood spatter patterns that forensic experts use to help determine how the victim died; luminol can also react with substances like bleach, rust, fizzy drink, and coffee, causing it to produce false positives; University of South Carolina rese3archers offer a better solution

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.

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.
