Powerful debugging program to help U.S. nuclear deterrence
Lawrence Livermore National Laboratory (LLNL) researchers have used the Stack Trace Analysis Tool (STAT), a highly scalable, lightweight tool to debug a program running more than one million MPI processes on the IBM Blue Gene/Q (BGQ)-based Sequoia supercomputer; LLNL plans to use Sequoia’s impressive computational capability to advance understanding of fundamental physics and engineering questions that arise in the National Nuclear Security Administration’s (NNSA) program to ensure the safety, security, and effectiveness of the U.S. nuclear deterrent without testing

Israel, for the first time since the October 1973 war, fires warning shots into Syria
The civil war in Syria has taken an ominous turn on Sunday as Israel, for the first time since the October 1973 Yom Kippur war, fired into Syria to warn the beleaguered Assad government that Israel would not tolerate shelling from Syrian territory into Israel; on four separate occasions last week, mortars from Syria fell in the Golan Heights, an area Israel captured from Syria in the 1967 war; it appears that the mortar fire was not intentional, but rather stray rounds, the result of errand shelling; on Saturday nine days ago, a few Syrian tanks entered a no-man’s land near the Israel border, in violation of the 1974 cease-fire and force-separation agreement between Israel and Syria

CIA-commissioned climate change report outlines perils for U.S. national security
U.S. national security leaders believe that the accelerating pace of climate change will place severe strains on U.S. military and intelligence agencies in coming years; the reason, according the National Research Council, the U.S. top scientific research body: climate changes will trigger increasingly disruptive developments around the world; a 206-page National Research Council study, commissioned by the CIA and other U.S. intelligence services, concludes that states will fail, large populations subjected to famine, flood, or disease will migrate across international borders, and national and international agencies will not have the capacity or resources to cope with the resulting conflicts and crises

Supreme Court to hear police DNA-collection case
The United States Supreme Court last week granted certiorari in Maryland v. King; in the case, Maryland law enforcement stands to lose the right to require a DNA collection as part of booking procedures for certain felony crimes; a similar law was passed by Congress in 2004 for federal arrests, and twenty-four other state legislatures have also passed such laws

Cleanup of most contaminated U.S. groundwater sites unlikely for many decades
At least 126,000 sites across the United States have contaminated groundwater that requires remediation, and about 10 percent of these sites are considered “complex,” meaning restoration is unlikely to be achieved in the next 50 to 100 years due to technological limitations; the estimated cost of complete cleanup at these sites ranges from $110 billion to $127 billion, but the figures for both the number of sites and costs are likely underestimates

Nanostructured material stronger than a speeding bullet
Providing protection against impacts from bullets and other high-speed projectiles is more than just a matter of brute strength; while traditional shields have been made of bulky materials such as steel, newer body armor made of lightweight material such as Kevlar has shown that thickness and weight are not necessary for absorbing the energy of impacts; new tests of nanostructured material could lead to better armor against everything from gunfire to micrometeorites

DARPA seeks multi-band, portable sensor to provide soldiers with clear images
Clip-on or helmet-mounted camera system would fuse useful aspects of visible, near infrared, and infrared images into a single shot under all weather and visibility conditions; the Pixel Network for Dynamic Visualization program, or PIXNET, technology would ingest the most useful data points from each component sensor and fuse them into a common, information-rich image that can be viewed on the soldier’s heads-up display, and potentially be shared across units

New strategy for fingerprint visualization
Identifying fingerprints on paper is a commonly used method in police forensic work, but it is not easy to make those fingerprints visible. Now, scientists have developed a new approach for making such fingerprints more readily readable

"Stutter jump" could improve performance of search and rescue robots
A new study shows that jumping can be much more complicated than it might seem; in research that could extend the range of future rescue and exploration robots, scientists have found that hopping robots could dramatically reduce the amount of energy they use by adopting a unique two-part “stutter jump”

Smart camera to describe what it sees -- and reason about what it cannot see
Army scouts are commonly tasked with covertly entering uncontrolled areas, setting up a temporary observation post, and then performing persistent surveillance for twenty-four hours or longer; what if instead of sending scouts on high-risk missions the military could deploy taskable smart cameras? A truly “smart” camera would be able to describe with words everything it sees and reason about what it cannot see

Approaches to international consequence management for CBRNE incidents
The National Research Council (NRC) of the National Academy of Sciences, through a grant sponsored by NIST’s Office of Law Enforcement Standards (OLES), is organizing an effort to understand the metrics and measures that are needed to develop standards of response that will support the basic capabilities of a country or region to respond to a chemical, biological, radiological, nuclear, or explosive (CBRNE) incident

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.”
“The Federal Government Is Gone”: Under Trump, the Fight Against Extremist Violence Is Left Up to the States
As President Donald Trump guts the main federal office dedicated to preventing terrorism, states say they’re left to take the lead in spotlighting threats. Some state efforts are robust, others are fledgling, and yet other states are still formalizing strategies for addressing extremism. With the federal government largely retreating from focusing on extremist dangers, prevention advocates say the threat of violent extremism is likely to increase.
Luigi Mangione and the Making of a ‘Terrorist’
Discretion is crucial to the American tradition of criminal law, Jacob Ware and Ania Zolyniak write, noting that “lawmakers enact broader statutes to empower prosecutors to pursue justice while entrusting that they will stay within the confines of their authority and screen out the inevitable “absurd” cases that may arise.” Discretion is also vital to maintaining the legitimacy of the legal system. In the prosecution’s case against Luigi Mangione, they charge, “That discretion was abused.”
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.
