ITT awarded contracts for land mine jammers
EDO makes the Warlock jammer, a derivative of its earlier “Shortstop” product; EDO has a new name for the anti-IED device — CVRJ (CREW Vehicle Receiver/Jammer) — and a new owner — ITT; company wins a new contract, worth up to $1 billion, for its jammer

Commercial use of invisibility cloak now within sight
Researchers engineer 3-D materials that can reverse the natural direction of visible and near-infrared light, thus forming the basis for higher resolution optical imaging — and for cloaking devices that could render objects invisible to the human eye

Using kites to generate electricity
The amount of power available from wind is related to the cube of its speed; blades at higher altitudes could thus generate up to five times the amount of electricity as at lower altitudes; why, then, not place blades at higher altitudes?

Edible optical sensor to watch for bacteria in food
Tufts University researchers demonstrate for the first time that it is possible to design “living” optical elements that could enable an entirely new class of sensors; these sensors would combine sophisticated nanoscale optics with biological readout functions, be biocompatible and biodegradable, and be manufactured and stored at room temperatures without use of toxic chemicals

Self-healing wire to bolster avaiation safety
In 1996 an explosion downed TWA flight 800 off the shore of Long Island, killing all 230 passengers and crew; University of Dayton researcher who identified a plausible cause of the explosion has developed a self-healing wire designed such explosions in the future

Bullet-tagging technology to help combat crime
U.K. researchers develop new bullet-tagging technology: tags are applied to gun cartridges by being embedded in cartridge coatings made from polylactic acid, sucrose ester, and tetrahydrofuran; the tags attach themselves to the hands or gloves of anyone handling the cartridge, but a portion of the tag remains on the cartridge even after it has been fired, making it possible to make a definite link between a cartridge fired during a crime and whoever handled it

China establishes itself as a physics powerhouse
Published journal articles in nanoscience, with at least one co-author based in China, have seen a 10-fold increase since the beginning of the millennium, rising to more than 10,500 in 2007; China has already overtaken the United Kingdom and Germany in the number of physics papers published and is beginning to nip at the heels of the United States; the verdict on the quality of many of these papers is still out

"Gravity tractor" could deflect asteroids, protect Earth
Spacecrafts have a weak gravitational pull; new NASA study says that if an asteroid was menacing Earth and was more than one orbit away from the potential impact, then deploying such a space craft — in effect, a gravity tractor — near the approaching asteroid would deflect the threatening object and save Earth

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.
