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

Nature's desalination: bacteria turn salty water fresh
The growing global shortage of water has led to a growing interest in desalination to produce fresh water from seas and estuaries; conventional desalination plants, however, consume large amounts of energy; the solution: a bug-powered desalination cell that takes salt out of seawater

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

Stealthy robo-snake to gather info in inaccessible areas
Israeli researchers develop a robotic snake that could be useful in urban and subterranean warfare, enabling the inspection and surveillance of sewage systems, narrow tunnels, or culverts, inaccessible by other systems; the robo-snake can maneuver through difficult terrain, “sneak” stealthily inside buildings, use its sensors to scan their interiors; the robot will be able to carry disposable sensors that could be separated and left behind to monitor activity inside buildings

Carnegie Mellon to develop flying car for DARPA
DARPA chooses Carnegie Mellon to develop autonomous capability for flying car; the military ground vehicle would transform into flyer for scouting, resupply, and medical evacuation; the flying car would be capable of transporting four people and 1,000 pounds of payload up to 250 nautical miles, either by land or by air

Breakthrough: Flapless UAV gets airborne
The conventional control surfaces of a UAV include many moving parts, require frequent, costly repairs, and account for a significant percentage of an aircraft’s noise output; British researchers developed a UAV with no moveable control surfaces — no flaps, ailerons, elevators, or spoilers; just a wing, an engine, and some holes

Securing the nation with fingerprinting materials
Lawrence Livermore National Laboratory (LLNL) researchers may have found a way to improve Raman spectroscopy as a tool for identifying substances in extremely low concentrations; potential applications for Raman spectroscopy include medical diagnosis, drug/chemical development, forensics and highly portable detection systems for national security.

9 million Euro project aims to develop stretchable electronic fabrics
Belgian researchers are working on developing smart electronic fabrics; the project will focus on making electronic packages conformable to the properties of textiles instead of just weaving rigid electrical components into fabrics; the fabric will also feature stretchable electrical interconnections

Laser has clinical, security applications
A novel laser system that could help detect bone diseases — and airport security; the spatially offset Raman spectroscopy (SORS) instrument uses a technique that allows it to scan deep into human tissue; the instrument is also being studied as a bottle and packaging scanner for airport security and is already used to assess the content of drugs

The long view
Are We Ready for a ‘DeepSeek for Bioweapons’?
Anthropic’s Claude 4 is a warning sign: AI that can help build bioweapons is coming, and could be widely available soon. Steven Adler writes that we need to be prepared for the consequences: “like a freely downloadable ‘DeepSeek for bioweapons,’ available across the internet, loadable to the computer of any amateur scientist who wishes to cause mass harm. With Anthropic’s Claude Opus 4 having finally triggered this level of safety risk, the clock is now ticking.”
Bookshelf: Preserving the U.S. Technological Republic
The United States since its founding has always been a technological republic, one whose place in the world has been made possible and advanced by its capacity for innovation. But our present advantage cannot be taken for granted.
Autonomous Weapon Systems: No Human-in-the-Loop Required, and Other Myths Dispelled
“The United States has a strong policy on autonomy in weapon systems that simultaneously enables their development and deployment and ensures they could be used in an effective manner, meaning the systems work as intended, with the same minimal risk of accidents or errors that all weapon systems have,” Michael Horowitz writes.
Ukraine Drone Strikes on Russian Airbase Reveal Any Country Is Vulnerable to the Same Kind of Attack
Air defense systems are built on the assumption that threats come from above and from beyond national borders. But Ukraine’s coordinated drone strike on 1 June on five airbases deep inside Russian territory exposed what happens when states are attacked from below and from within. In low-level airspace, visibility drops, responsibility fragments, and detection tools lose their edge. Drones arrive unannounced, response times lag, coordination breaks.
Shots to the Dome—Why We Can’t Model US Missile Defense on Israel’s “Iron Dome”
Starting an arms race where the costs are stacked against you at a time when debt-to-GDP is approaching an all-time high seems reckless. All in all, the idea behind Golden Dome is still quite undercooked.
Our Online World Relies on Encryption. What Happens If It Fails?
Quantum computers will make traditional data encryption techniques obsolete; BU researchers have turned to physics to come up with better defenses.
Virtual Models Paving the Way for Advanced Nuclear Reactors
Computer models predict how reactors will behave, helping operators make decisions in real time. The digital twin technology using graph-neural networks may boost nuclear reactor efficiency and reliability.
Critical Minerals Don’t Belong in Landfills – Microwave Tech Offers a Cleaner Way to Reclaim Them from E-waste
E-waste recycling focuses on retrieving steel, copper, aluminum, but ignores tiny specks of critical materials. Once technology becomes available to recover these tiny but valuable specks of critical materials quickly and affordably, the U.S. can transform domestic recycling and take a big step toward solving its shortage of critical materials.
Microbes That Extract Rare Earth Elements Also Can Capture Carbon
A small but mighty microbe can safely extract the rare earth and other critical elements for building everything from satellites to solar panels – and it has another superpower: capturing carbon dioxide.
