• Beaver-Like Dams Can Enhance Existing Flood Management Strategies for At-risk Communities

    River barriers made up of natural materials like trees, branches, logs and leaves can reduce flooding in at-risk communities. Leaky barriers are effective in slowing down the flow of the river during periods of rainfall and storing up vast quantities of water which would otherwise rush through causing damage to communities downstream.

  • Reached: Milestone in Power Grid Optimization on World’s First Exascale Supercomputer

    By Jeremy Thomas

    Ensuring the nation’s electrical power grid can function with limited disruptions in the event of a natural disaster, catastrophic weather or a manmade attack is a key national security challenge. Compounding the challenge of grid management is the increasing amount of renewable energy sources such as solar and wind that are continually added to the grid, and the fact that solar panels and other means of distributed power generation are hidden to grid operators.

  • Aging Bridge Detection Through Digital Image Correlation

    Researchers have developed a novel and practical method of assessing the mechanical properties of structures, with potential application to structural health monitoring of large structures such as bridges and viaducts.

  • Senate Fails to Reauthorize Chemical Facility Security Program

    Chemical industry groups are warning that thousands of chemical facilities across the United States could face increased risk of terrorist attacks after the Senate last week adjourned for its summer recess without approving pending House legislation reauthorizing the Chemical Facility Anti-Terrorism (CFATS) program.

  • “Hacking” People, Not Systems: False Claims Attacks on Infrastructure

    By Joshua DeLozier

    False claims and disinformation, especially in a social media-driven society, have become major problems with potentially severe consequences. Disinformation can be weaponized to disrupt underlying cyber-physical systems, human lives and economic productivity. Recent examples include tweets that trigger spikes in gasoline prices and false social media posts reporting impending water pumping station shutdowns. In these scenarios, chaos is caused because people, not systems or devices, are “hacked.”

  • Baltic States Seek to Decouple Their Power Grids from Russia

    Estonia, Lithuania and Latvia are seeking to disconnect from an energy grid network shared with Russia and Belarus by early 2025. Vilnius is pushing from an earlier exit from the grid, which Tallin opposes.

  • The Nuclear Arms Race’s Legacy at Home: Toxic Contamination, Staggering Cleanup Costs and a Culture of Government Secrecy

    By William J. Kinsella

    The Manhattan Project spawned a trinity of interconnected legacies. Among other things, it led to widespread public health and environmental damage from nuclear weapons production and testing. And it generated a culture of governmental secrecy with troubling political consequences.

  • New National Cyber Workforce and Education Strategy

    Hundreds of thousands of cyber jobs in government and the private sector are vacant, and the administration says that filling them is a national security imperative. Today, the administration unveiled its ambitious National Cyber Workforce and Education  Strategy (NCWES) which aims at addressing both short-term needs and long-terms requirements.

  • Bringing Resilience to Small-Town Hydropower

    Using newly developed technologies, researchers demonstrated how hydropower with advanced controls and use of a mobile microgrid, can enable small communities to maintain critical services during emergencies.

  • One in Five Texans Lives in a Floodplain

    By Erin Douglas

    Almost 6 million Texans, or about 20% of the population, live in an area susceptible to flooding and one-fifth of the state’s land is in a 100-year floodplain. Texas launched a statewide effort to harden Texas against floods and rising sea levels.

  • How Well-Managed Dams and Smart Forecasting Can Limit Flooding as Extreme Storms Become More Common in a Warming World

    By Riley Post

    The United States is home to over 50,000 operable reservoirs that are overseen by dozens of state and federal agencies. As rising global temperatures make extreme storms more common, the nation’s dams and reservoirs – crucial to keeping communities dry – are being tested.

  • Moving Communities Away from Flooding Risks with Minimal Harm

    By Rob Jordan

    As sea levels rise and flooding becomes more frequent, many countries are considering a controversial strategy: relocation of communities. A Stanford analysis of planned relocations around the world reveals a blueprint for positive outcomes.

  • Germany Will Rely on Imports for Its Growing Hydrogen Needs

    By Sabine Kinkartz

    Revisiting its national hydrogen strategy (NHS), the German government foresees a huge need for hydrogen. By 2030, hydrogen consumption may hit 130 terawatt hours — that is more than one-fifth of all current electricity consumption in Germany. But Germany will need to import as much as 70% of it.

  • An American View on U.S. Investment in Critical-Mineral Mining in Australia

    By Shubham Dwivedi and Gregory D. Wischer

    In May, the United States and Australia signed a compact which, among other things, aims to coordinate policies and investments to support the expansion and diversification of critical minerals supply chains. In this case, diversification basically equates to reducing dependence on China, in which various links in the critical-mineral supply chain are heavily concentrated.

  • One- to Four-Family Properties with Multiple Losses Insured by the National Flood Insurance Program

    What are the characteristics of properties that have experienced multiple flood losses (e.g., percentage of overall claims payments, number of losses, and structure characteristics)? What are the socioeconomic characteristics of multiple loss property (MLP) households and the communities in which they are located? What percentage of MLPs have been mitigated, what are the socioeconomics characteristics of neighborhoods where MLPs have been mitigated, and how effective has mitigation been in reducing risk?
