Don’t Bring a Patriot to a Drone Fight—Bring Fighter UAVS Instead
Recent conflicts such as the war in Ukraine and the 2020 war in Nagorno-Karabakh demonstrate the growing importance of unmanned aerial vehicles. Naturally, there have been attempts to defeat this new threat. No matter the defense mechanism chosen, there just are not enough systems to provide sufficient protection against swarms of UAVs. The solution for this dilemma is to take the next step in UAV evolution: air superiority drones.

Norway the First in the World to Approve Seabed Mining. Is It a Good Idea?
The transition to a greener, renewable economy will require large amounts of minerals, and society has to get them from somewhere. Norwegian politicians have reached an agreement approving deep sea mining, in a proposal that has reaped both cheers and frustration from scientists and activists alike. Here’s what our scientists think.

“Killer Robots” Are Coming, and UN Is Worried
Long the stuff of science fiction, autonomous weapons systems, known as “killer robots,” are poised to become a reality, thanks to the rapid development of artificial intelligence. In response, international organizations have been intensifying calls for limits or even outright bans on their use. Human rights specialist lays out legal, ethical problems of military weapons systems that attack without human guidance.

California’s Salton Sea Region a Rich Domestic Lithium Resource
The United States currently has limited capabilities to recover, refine, and produce domestically sourced lithium, meaning nearly all lithium for U.S. needs must be imported. The most comprehensive analysis to date quantifying the domestic lithium resources in southern California’s Salton Sea region found that the total resources in the region could contain more than 3,400 kilotons of lithium, enough to support over 375 million batteries for electric vehicles (EV).

Cyber 'Kidnapping' Scams Target Chinese Students Around the World
A recent cyber kidnapping incident involving a Chinese exchange student in Utah appears to be part of an international pattern in which unknown perpetrators, often masquerading as Chinese police or government officials, target Chinese students around the world and extort their families for upwards of tens of thousands of dollars.

Saving Seconds, Saving Lives: NIST-Funded Challenge Crowns Winners in 3D Tracking Technology
NIST has awarded $1.9 million to six teams for innovative 3D tracking solutions in the final phase of a competition. The winning designs combine localization and biometric monitoring, using sensors affixed to first responders’ equipment. This competition is part of an $8 million NIST-funded initiative to address first responders’ need for improved tracking in emergency settings where GPS falls short.

Researchers Release Open-Source Space Debris Model
With the escalating congestion in low Earth orbit, driven by a surge in satellite deployments, the risk of collisions and space debris proliferation is a pressing concern. Conducting thorough space environment studies is critical for developing effective strategies for fostering responsible and sustainable use of space resources. The MIT Orbital Capacity Assessment Tool lets users model the long-term future space environment.

Extreme Weather Cost $80 Billion in 2023. The True Price Is Far Higher.
The U.S. saw 25 billion-dollar weather disasters in 2023 — more than ever before. 2024 could be worse. Congress has long punted on reforming FEMA and the nation’s disaster relief policy, but it’s only a matter of time before there’s a disaster bad enough that legislators feel pressure to act. That catastrophe didn’t arrive in in 2023, but it is surely coming.

Number of People Affected by Tropical Cyclones Has Increased Sharply Since 2002
The number of people affected by tropical cyclones has nearly doubled from 2002 to 2019, reaching nearly 800 million people in 2019, according to a new study. More people are affected by tropical cyclones in Asia than any other region, but every affected world region saw an increase in the number of people exposed to tropical cyclones, which are expected to become more intense and possibly more frequent as the climate warms.

Identifying Types of Cyberattacks That Manipulate Behavior of AI Systems
AI systems can malfunction when exposed to untrustworthy data – what is called “adversarial machine learning” — and attackers are exploiting this issue. New guidance documents the types of these attacks, along with mitigation approaches. No foolproof method exists as yet for protecting AI from misdirection, and AI developers and users should be wary of any who claim otherwise.

Electric vs. Gasoline Vehicles: Is EV Ownership Competitive in Your Area?
Is it actually cheaper to own an electric vehicle instead of a gas vehicle? It depends. Researchers say that where you live matters. Cumulative recurring costs for a midsize SUV across platforms—traditional gasoline, hybrid and electric—are higher in some cities when taking key factors into account: financing, annual fees, insurance, maintenance, repairs and fuel costs.

Revolutionizing Resource Renewal: Scaling Up Sustainable Recycling for Critical Materials
Permanent magnets, which retain magnetic properties even in the absence of an inducing field or current, are used extensively in clean energy and defense applications. Rare earths are challenging to access because they are scattered across Earth’s crust, yet they are key components in many modern technologies. Recycled rare earths can be used to make new permanent magnets, accelerate chemical reactions and improve the properties of metals when included as alloy components.

Autonomous Vehicle Technology Vulnerable to Road Object Spoofing and Vanishing Attacks
Researchers have demonstrated the potentially hazardous vulnerabilities associated with the technology called LiDAR, or Light Detection and Ranging, many autonomous vehicles use to navigate streets, roads and highways. The researchers have shown how to use lasers to fool LiDAR into “seeing” objects that are not present and missing those that are – deficiencies that can cause unwarranted and unsafe braking or collisions.
Tantalizing Method to Study Cyberdeterrence
Tantalus is unlike most war games because it is experimental instead of experiential — the immersive game differs by overlapping scientific rigor and quantitative assessment methods with the experimental sciences, and experimental war gaming provides insightful data for real-world cyberattacks.
Prototype Self-Service Screening System Unveiled
TSA and DHS S&T unveiled a prototype checkpoint technology, the self-service screening system, at Harry Reid International Airport (LAS) in Las Vegas, NV. The aim is to provide a near self-sufficient passenger screening process while enabling passengers to directly receive on-person alarm information and allow for the passenger self-resolution of those alarms.
