Low-cost security imaging device uses inexpensive radio components
Currently, scanning devices that detect hidden weapons or contraband in airports rely on millimeter-wave cameras, which can cost more than $175,000. The cost of the technology is a significant limiting factor in determining where, and whether, to use these scanners. Researchers have used computer models to demonstrate the viability of a low-cost security imaging device that makes use of inexpensive radio components.

New alert system aims to protect responders, drivers at roadway incident scenes
Whether distracted by the latest cell phone game, driving while intoxicated, driving carelessly, or in low-visibility scenarios, the trend of first responder roadside strikes unfortunately looks likely to continue. DHS S&T has chosen Applied Research Associates, Inc. of Albuquerque, New Mexico, to develop technology that aims to reduce dangerous vehicle strikes on first responders. The project will integrate several existing technologies into a system that can be easily deployed.

NYC terrorist captured: What we know so far
Ahmad Khan Rahami, the suspect in placing two bombs in Manhattan on Saturday – one of them exploded, injuring twenty-nine people, while the other was disarmed — has been arrested in Linden, New Jersey. He was spotted by residents sleeping in a vestibule next to a bar, and they called the police. Fire was exchanged as the police closed in on him, and two policemen, and Rahami himself, were injured, but not seriously. The Rahami family’s chicken restaurant had problems city ordinances in Elizabeth, New Jersey, and in 2011 the family sued that city and its police department for discrimination and harassment.

X-ray vision: Bomb technicians strengthen their hand with Sandia’s XTK software
X-Ray Toolkit (XTK), an image-processing and analysis software developed at Sandia National Laboratories, has been adopted by the military and emergency response communities in the United States and around he world. “XTK is the standard in the field not only nationally, but internationally. It made the average bomb tech a better bomb tech,” said Craig Greene, a special agent and bomb technician at the Albuquerque, New Mexico FBI. “In the past twenty years, the bomb technician community has progressed from the Stone Age to the twenty-first century in terms of equipment and procedures, and XTK is a major part of that progression.”

What causes mass panic in emergency situations?
In emergency situations such as terrorist attacks, natural catastrophes, and fires, there is always a risk of mass panic leading to deadly crowd disasters. But what causes mass panic and where are the danger zones? Because these questions are difficult to study in the real world, researchers exposed experiment participants to an emergency in a three-dimensional virtual environment.

Climate change poses “strategically significant risk” to U.S. national security
Twenty-five national security and military leaders the other day released a statement declaring that: “the effects of climate change present a strategically-significant risk to U.S. national security,” and urging a “comprehensive policy” in response. The authors of the statement say that stresses resulting from climate change can increase the likelihood of intra or international conflict, state failure, mass migration, and the creation of additional ungoverned spaces, across a range of strategically-significant regions. They add that the impacts of climate change will place significant strains on international financial stability through contributing to supply line disruptions for major global industries in the manufacturing, energy, agriculture, and water sectors, disrupting the viability of the insurance industry, and generally increasing the political and financial risks of doing business in an increasingly unstable global environment.

Disaster communications: Lessons from 9/11
What we and the other responders learned on 9/11, under the pressure of a disaster of incredible scale, scope and urgency – not to mention the international media spotlight – went on to spark major changes in U.S. emergency response communication. By ensuring that – no matter what happens – we can communicate with each other, the emergency response community keeps the memory of 9/11 alive in our own way every single day.

U.S. destroys large ISIS chemical weapons manufacturing facility
The U.S. on Monday destroyed an ISIS chemical manufacturing facility in Iraq, which posed a “significant chemical [weapons] threat.” Footage of Monday air strikes showed twelve aircraft hitting a sprawling industrial site in Mosul. The hits were followed by huge explosions in multiple buildings and storage facilities. The buildings were quickly engulfed by flames, and heavy plumes of dark smoke rose into the air. USAF spokesman said that fifty individual targets were hit in the attack.

Command under attack: What we’ve learned since 9/11 about managing crises
Major disasters pose difficult challenges for responders on the ground and for higher-level officials trying to direct operations. Some events are novel because of their scale, while others involve challenges that no one may ever have envisioned. Communities need to bring their response agencies together regularly to plan and practice. This can develop and maintain knowledge and relationships that will enable them to work together effectively under the high stress of a future attack or disaster. Any community can do this, but many have not. Where training and practice have taken place, these tools have worked. They can be improved, but the most important priority is getting more communities to practice using them more regularly, before the next disaster. One important way this nation can honor the victims of 9/11 is by using these lessons to create the conditions for even better coordination in future events.

New forensic method identifies people using human hair proteins
In an important breakthrough for the forensic science community, researchers have developed the first-ever biological identification method that exploits the information encoded in proteins of human hair. The new protein identification technique will offer another tool to law enforcement authorities for crime scene investigations and archaeologists, as the method has been able to detect protein in human hair more than 250 years old.

Tsunami evacuation plans: A case study in Alameda, California
Tsunami evacuation planning in coastal communities is typically based on maximum evacuation zones that reflect a combination of all potential extreme tsunamis. However, in the case of a smaller tsunami, this approach may result in more people being evacuated than need to be, and in doing so, may overly disrupt the local economy, and strain resources needed during emergency response. Evacuations are intended to keep a population safe and reduce losses, but what are the costs of lost work and wages, or accidental injuries that may occur during an evacuation?

N. Korea’s test of miniaturized warhead, submarine-launched ballistic missile, are game changers
North Korea has conducted its fifth nuclear test last night, marking the 68th anniversary of the nation’s founding. Military analysts say the test shows a worrisome improvement in North Korea’s nuclear capabilities: It was the most powerful nuclear test to date, with a 10-kiloton yield – slightly smaller than the yield of the bomb dropped on Hiroshima, estimated to have been between twelve and eighteen kilotons. The warhead tested in the explosion was miniaturized, indicating that North Korea now has the capability to mount a nuclear warhead on a missile. Last night’s test, together with North Korea’s proven progress in launching ballistic missile from submarines, mean that the country is getting closer to possessing a nuclear arsenal capable of hitting the United States.

Report: Hamas spends $100 million annually to build up its military infrastructure
Hamas spends an annual $100 million on its military infrastructure in order to prepare for its next war against Israel. Roughly $40 million is spent on employing around 1,500 diggers to build the Iran-backed terror organization’s network of tunnels. Despite the financial hardships experienced by Gaza residents, Hamas, which in 2014 had a budget of around $530 million, is intent on increasing its military spending. In addition to digging tunnels, it hopes to upgrade its capabilities, which were degraded during its war with Israel two years ago, and is seeking to develop more precise rockets that could evade Israel’s Iron Dome defensive shield.

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.
