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.

Australia Should Learn from Canada and Take a Truly Global Approach to Critical Minerals
Canada and Australia are key players in the global supply chain for critical minerals. Simultaneously the top two nations for receiving minerals investment and for providing minerals investment, they are perfectly placed to use critical minerals to facilitate the global energy transition, foster innovation and build their security capabilities.

Speedier Security Screening in the Palm of the Hand
Though pat downs are currently an essential element of keeping travelers safe at the airport, it slows the screening process for people waiting in line and can be an uncomfortable experience for the passenger being screened. Reducing the need for pat downs may soon be easier.

Future Floods: Global Warming Intensifies Heavy Rain – Even More Than Expected
The intensity and frequency of extreme rainfall increases exponentially with global warming, a new study finds. The study shows that state-of-the-art climate models significantly underestimate how much extreme rainfall increases under global warming – meaning that extreme rainfall could increase quicker than climate models suggest.

Evolution Might Stop Humans from Solving Climate Change
Central features of human evolution may stop our species from resolving global environmental problems like climate change, says a new study. Can humans continue to survive on a limited planet? “We don’t have any solutions for this idea of a long-term evolutionary trap, as we barely understand the problem,” says one expert.

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.
