"Fingerprinting" RFID tags will prevent counterfeiting
RFID tags embedded in objects will become the standard way to identify objects and link them to the cyberworld; trouble is, it is easy to clone an RFID tag by copying the contents of its memory and applying them to a new, counterfeit tag, which can then be attached to a counterfeit product — or person, in the case of these new e-passports; researchers develop an electronic fingerprinting system to prevent this from happening

GE Global Research to develop wearable RFID chemical sensor
GE Global Research will develop a wearable radio-frequency-identification (RFID) sensors to alert people to the presence of chemicals in the air; as the sensors can be made at a size smaller than a penny, they could form part of an identification badge that would provide an early warning for people about the presence of chemical agents

NASA develops chemical-detection app for iPhone
NASA’s Homeland Security Cell-All program has developed an intriguing application to Apple’s phone in the form of a stamp-sized chemical sniffing device; the prototype chemical sensor can sniff small amounts of chemicals like methane, ammonia, and chlorine gas

Interference-free radio from Cambridge Consultants
Cambridge Consultants shows a novel “spectral sensing” cognitive radio technology that will allow any radio product to transmit without interference over the so-called “whitespace” frequencies recently vacated by the U.S. digital TV switchover

DARPA looking for methods to freeze soldiers with brain injuries
Traumatic brain injuries are caused by repeated exposure to blasts, specifically the “supersonic wave” of highly-pressurized air they emit; within a fraction of a second after impact, brain cells, tissues, and blood vessels are stretched, torn, and distorted; over the hours, days, and months that follow, altered brain processes create a snowball effect of damage — which is why symptoms often don’t show up until troops come home; in its solicitation, DARPA notes that a portable brain-cooling unit, deployed in the field, could “extend the golden hour of patient survivability and increase the chances for full recovery”

E.coli helps mend cracked pipes
Aberdeen University students show how specific strains of E. coli, which are not deadly or poisonous to humans, could be used automatically to mend cracks that occur in household water pipes, cooling pipes in laboratory experiments, or water pipes in power plants

Imperial College London awarded £4.9 million to research cloaking properties of metamaterials
Metamaterials have properties that could lead to the development of invisibility “cloaking” devices, sensitive security sensors, and flat lenses that can be used to image objects much smaller than the wavelength of light; Imperial College London receives a £4.9 million grant to do research on metamaterials

Ricin antidote ready for production
U.K. scientists develop the first antidote to ricin poisoning; security experts say ricin — roughly 1,000 times more toxic than cyanide — could be used in a bio-terror attack; what worries experts about ricin is not only its toxicity, but its ready availability: Ricin is extracted from castor beans, which are processed throughout the world to make castor oil; the toxin is part of the waste “mash” produced when castor oil is made

Downtown airport boasts a new runway safety system
Safety barriers made of new type of absorbing concrete are installed at a Kansas City airport; the barriers are made of concrete blocks which collapse to absorb the energy of the airplane while minimizing the damage to the aircraft and allowing the aircraft to be slowed without hurting passengers

U.S. Congress holds hearings on geoengineering
Geoengineering — the effort to design systems which would change the world’s climate — was once a fringe phenomenon; it has been moving into the mainstream, though, as more and more scientists are growing increasingly concerned that, even if we commit to cutting emissions drastically, we have already waited too long, and that by the time we actually reduce emissions, enough greenhouse gases will have accumulated to cause serious climate disasters

Iran tested advanced nuclear warhead design
The “two-point implosion” is one of the most guarded secrets in nuclear weapons states; yet Iranian engineers, in what Western nuclear experts describe as a breakthrough, has tested such a design, which much be described as a giant leap in acquiring nuclear weapons

New communication system to help protect soldiers in the field
The new technology will use arrays of highly specialized antennas that could be worn by combat troops to provide covert short-range person-to-person battleground communications; the technology will lead to advanced wireless systems that would enable small squads of soldiers to share real-time video, covert surveillance data and tactical information with each other via helmet-mounted visors

First winner in space elevator competition
The contest requires their machines to climb 2,953 feet (nearly 1 kilometer) up a cable slung beneath a helicopter hovering nearly a mile high; the vehicle from the Kansas City-based LaserMotive zipped up to the top in just over four minutes and immediately repeated the feat, qualifying for at least a $900,000 second-place prize

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.

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.
