• Extreme Weather Cost $80 Billion in 2023. The True Price Is Far Higher.

    By Jake Bittle

    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

    By Ian Satchwell

    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.

  • Plagues, Cyborgs, and Supersoldiers: The Human Domain of War

    How have advancements in biotechnology affected warfighting, and how could they do so in the future? Can the human body itself be a warfighting domain? Can the body itself be an offensive or defensive weapon?

  • In Coastal Communities, Sea Level Rise May Leave Some Isolated

    By Tatyana Woodall

    Amid the threat of dramatic sea level rise, coastal communities face unprecedented dangers, but a new study reveals that as flooding intensifies, disadvantaged populations will be the ones to experience some of the most severe burdens of climate change.

  • 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.

  • The Link Between Climate Change and a Spate of Rare Disease Outbreaks in 2023

    By Zoya Teirstein

    The temperature-sensitive pathogens that caught U.S. communities off guard are a grim preview of the future. Scientists have warned that climate change would alter the prevalence and spread of disease in the U.S., particularly those caused by pathogens that are sensitive to temperature.

  • Seven Moments in December that Changed Nuclear Energy History

    December is a big month in the history of nuclear energy. From the first self-sustaining chain reaction to a pivotal breakthrough in nuclear fusion, some of the biggest events that laid the foundation for the nuclear energy sector all happened in the final month of the year.

  • Leveraging Artificial Intelligence in Explosives, Narcotic Detection

    DHS S&T is applying emerging technologies in the development of artificial intelligence / machine learning technologies – and searching for ways to use these technologies to identify dangerous compounds, like those found in explosives and narcotics.

  • Enhancing Coastal Cities' Flood Resilience Through Smart City Technologies

    In the face of climate change, a suite of advanced technologies can be integrated into urban design to reduce the flood risk posed by rising sea levels, more intense rainfall events, and more powerful storm surges.
