Pentagon wants laser attack warnings for satellites
The U.S. economy and military capabilities are dependent on satellites for communication and information gathering; growing anti-satellite warfare capabilities — for example, by China — lead Pentagon to seek a measure of protection for space-based assets

Cheap carbon trap cleans up power station emissions
Sequestering CO2 is a good way to fight global warming, but only about 10 percent of the gas produced in the process of burning fossil fuels is CO2; most of the rest is nitrogen, which is not a greenhouse gas; there is a new, inexpensive way to separate the two

IAEA: Iran evasive about its nuclear program
Iran’s march toward the bomb continues unabated; the U.S. intelligence community may have concluded that Iran had “halted” its nuclear weapons program in 2003, but a UN atomic agency says indications are to the contrary

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.
