• You've Heard of Water Droughts. Could “Energy” Droughts Be Next?

    In a new modeling study, researchers show how widely wind and solar potential vary by season and year, suggesting that backup energy sources may be needed as the world shifts to renewables to bring carbon emissions to zero.

  • New Wildfire Detection System Receives Funding Boost

    The high intensity of the recent fire seasons in Oregon, coupled with the increasing wildfire risk this year as approximately three-quarters of the state is now in severe drought conditions, has highlighted how critical a new project, aiming to help with the early detection and monitoring of wildfires, is — both for firefighters and the general public.

  • New National Water Alliance Aims to Predict Water-Related Hazards, Manage U.S. Water Resources

    The new Cooperative Institute for Research to Operations in Hydrology (CIROH) is composed of 28 academic institutions, non-profit organizations, and government and industry partners across the United States and Canada, aiming to better predict water-related hazards and manage the nation’s water resources.

  • The Financial Risks of Water Resilience Planning in California

    California’s Water Resilience Portfolio Initiative is a multi-billion dollar effort that encourages different water utilities and irrigation districts to work together to build shared infrastructure to reduce the effects of droughts, but a number of questions remain regarding how best to structure these agreements.

  • The Future of 5G+ Infrastructure Could Be Built Tile by Tile

    Currently 5G+ technologies rely on large antenna arrays that are typically bulky and come only in very limited sizes, making them difficult to transport and expensive to customize. Researchers have developed a novel and flexible solution to address the problem. Their additively manufactured tile-based approach can construct on-demand, massively scalable arrays of 5G+‐enabled smart skins with the potential to enable intelligence on nearly any surface or object.

  • Can Nuclear Generation Help Reduce European Reliance on Russian Gas?

    Following Russia’s invasion of Ukraine, the International Energy Agency and the European Commission have come up with plans to rapidly reduce the European Union’s imports of Russian natural gas. While the International Energy Agency anticipates that EU nuclear generation could increase by 20 terawatt hours (TWh) (or 2.7 percent) in 2022, the European Commission only mentions nuclear as a potential source of hydrogen.

  • How Ukraine Has Defended Itself Against Cyberattacks – Lessons for the U.S.

    In 2014, as Russia launched a proxy war in Eastern Ukraine and annexed Crimea, and in the years that followed, Russian hackers hammered Ukraine. The cyberattacks went so far as to knock out the power grid in parts of the country in 2015. Russian hackers stepped up their efforts against Ukraine in the run-up to the 2022 invasion, but with notably different results. Those differences hold lessons for U.S. national cyber defense.

  • Uranium Detectable in Two-Thirds of U.S. Community Water System Monitoring Records

    A study on metal concentrations in U.S. community water systems (CWS) found that metal concentrations were particularly elevated in CWSs serving semi-urban, Hispanic communities independent of location or region.

  • Shared Water Resources: Source of Both Peace and Conflict

    From the Euphrates to the Mekong, dams that ensure one country’s water supply risk leaving others parched. But shared water resources can be a source of peace as well as conflict.

  • Marine Energy Is Finally Here

    Is marine energy finally here? The simple answer is yes, the ocean—specifically clean energy generated from waves, tides, and ocean and river currents—can help save the planet. Revamped software offers marine energy industry the data it needs to succeed.

  • Russia’s Energy Clout Doesn’t Just Come from Oil and Gas – It’s Also a Key Nuclear Supplier

    As Western nations look for ways to reduce their reliance on Russian oil and gas, another aspect of the Ukraine crisis has received less attention: Most of the 32 countries that use nuclear power rely on Russia for some part of their nuclear fuel supply chain. Economic fallout from the war in Ukraine could disrupt access to fuel for the nuclear power industry.

  • Protecting Solar Technologies from Cyberattack

    At a solar farm, power electronics devices convert direct current (DC) electricity generated by solar photovoltaic panels into alternating current (AC) electricity for use on the electrical grid. The U.S. Department of Energy estimates up to 80% of electricity could flow through power electronics devices by 2030. Researchers suggest a novel approach to safeguarding one possible target of a cyberattack – the nation’s solar farms.

  • Testing Similitude Laws of Multistory Masonry Buildings

    Earthquakes and other stressors on buildings pose a threat to their structural integrity that endangers human life. It helps to be able to calculate the behavior of buildings and test with small-scale models.

  • Cyber and Physical Security Should Collaborate: What Does It Take to Achieve This

    To understand and mitigate threats that cross the boundary between what is cyber and what is physical, some organizations have integrated their security resources to encourage them to work more closely together.

  • Giving New Life to Old Concrete Structures Through “Vascularization”

    Concrete is a ubiquitous building material, and it is often cited as the most consumed commodity on Earth, second only to potable water. As this inherited concrete infrastructure continues to age, maintaining and repairing concrete is of increasing strategic importance to both defense and civilian infrastructure. DARPA’s BRACE program aims to revitalize legacy DoD infrastructure to extend its serviceability.
