UAVs-mounted aircraft defense system demonstrated
Until now there have been two leading approaches to protecting civilian aircraft from shoulder-fired missiles: One approach proposed placing the defensive systems on the planes to be protected, the other advocated surrounding airports with a protective umbrella; a third approach has now been demonstrated: Mounting defensive systems on UAVs loitering high in the sky

IT security hinders innovation
New IDC reports says businesses are struggling to find the right balance between security and innovation; information security concerns have caused 80 percent of companies surveyed to back away from new innovation opportunities

Better coastal defenses against large waves
Coastal defenses have to withstand great forces and there is always a risk of water overtopping or penetrating these structures; Liverpool University’s mathematician says we need new concepts for coastal defenses

More on the danger of GPS spoofing
The military version of GPS includes security features such as encryption, but civilian signals are transmitted in the clear, unencrypted; a suitcase-size transmitting device can easily fool a GPS receiver; the power grid may be disrupted, and ankle-bracelet-wearing criminals walk about freely

Northrop Grumman delivers first, if under-powered, raygun to U.S. military
The U.S. military wants a beam weapon capable of at least 100 KW to shoot down incoming artillery shells or missiles; Northrop’s Vesta II can offer only 15 KW — capable of disrupting cellphone towers, car engines, and unexploded munitions; it is a start

DARPA seeks ultrasonic tourniquets
New device, placed on the arm or a leg of an injured soldier or first responder will use ultrasound scanning to pinpoint internal bleeding, before focusing “high-power energy” on the bleed sites

UCLA group discovers largest Mersenne prime yet
Bruins researchers discover the 46th — and largest yet — Mersenne Prime; the 13 million-digit prime number is a long-sought milestone, and its discovery makes the researchers eligible for a $100,000 prize

Invisibility cloak as a protection against tsunamis
Rather than fortifying sea platforms and coastal towns to withstand tsunamis, it may be possible to use invisibility cloaks to make off-shore platforms, islands, and even cities “invisible” to waves

Northrop tests Guardian anti-missile system
On 8-9 September, Northrop Grumman successfully tested the Guardian anti-missile system; from heights exceeding 50,000 feet, the system successfully detected, tracked, and directed a laser to intercept a target missile

Breakthrough: "Math dyslexia," not intelignece, makes people bad at math
Generations of students who struggled with mathematics in school accepted — and their teachers and parents accepted — that they were just “not good at math”; new research show that the cause was more likely “dyscalculia” — a syndrome which is similar to dyslexia

More debate about how best to defend Earth against asteroids
U.C. Berkeley expert says protecting Earth against incoming asteroids “is not an astronomy problem. It is a financial problem, an accounting problem, an international problem, an organizational problem, a political problem”

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.
