• We Could Soon Be Getting Energy from Solar Power Harvested in Space

    The idea of space-based solar power (SBSP) – using satellites to collect energy from the sun and “beam” it to collection points on Earth – has been around since at least the late 1960s. Despite its huge potential, the concept has not gained sufficient traction due to cost and technological hurdles. space-based solar power is technologically feasible, but to be economically viable, it requires large-scale engineering, and therefore long-term and decisive commitment from governments and space agencies.

  • Heat, Drought, Population Growth Stress Aquifers Which Supply Water to Millions of Texans

    Diminishing springs and aquifers due to heat, drought and high for demand water highlight the urgency for Central Texas conservation districts to prioritize climate-focused management, potentially involving reduced pumping for sustainability.

  • Tech Breakthrough Could Increase States’ Use of Geothermal Power

    Lawmakers in some states have been laying the groundwork to add geothermal power to the electrical grid and pump underground heat into buildings. Now, a technological breakthrough could dramatically expand those ambitions — and perhaps unleash a new wave of policies to tap into geothermal sources. If the technology’s promise is fulfilled, geothermal could power as much as 20% of the U.S. grid.

  • FEMA Maps Said They Weren’t in a Flood Zone. Then Came the Rain.

    The most common reference for flood risk are the flood insurance rate maps, also known as 100-year floodplain maps, that the Federal Emergency Management Agency, or FEMA, produces. They designate so-called special flood hazard areas that have a roughly 1 percent chance of inundation in any given year. Properties within those zones are subject to more stringent building codes and regulations that, among other things, require anyone with a government-backed mortgage to carry flood insurance. Flaws in federal flood maps leave millions unprepared. Some are trying to fix that.

  • Major Update to NIST’s Widely Used Cybersecurity Framework

    The world’s leading cybersecurity guidance is getting its first complete makeover since its release nearly a decade ago. NIST has revised the framework to help benefit all sectors, not just critical infrastructure.

  • DHS: Additional $374.9 Million in Funding to Boost State, Local Cybersecurity

    State and local governments face increasingly sophisticated cyber threats to their critical infrastructure and public safety. On Monday, DHS announced the availability of $374.9 million in grant funding for the Fiscal Year (FY) 2023 State and Local Cybersecurity Grant Program (SLCGP).

  • 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

    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

    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

    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.
