• Will Germany Return to Nuclear Power?

    As Germany moves to wean itself off Russian energy, politicians are debating a pause to the country’s planned nuclear phaseout. Experts warn, however, that it may not be so easy.

  • Climate Changes Lead to Water Imbalance, Conflict in Tibetan Plateau

    Climate change is putting an enormous strain on global water resources, and according to researchers, the Tibetan Plateau is suffering from a water imbalance so extreme that it could lead to an increase in international conflicts.

  • Nuclear Forensics International Group Anniversary Meeting at Livermore

    After a little more than 25 years, the Nuclear Forensics International Technical Working Group (ITWG) is returning to its roots in Livermore, California. Founded in 1995 in a meeting at Lawrence Livermore National Laboratory (LLNL), the ITWG met in Europe for 24 straight years from 1996 through 2019.

  • Developing Novel Hybrid Reef-Mimicking Structures

    Despite previous efforts to implement storm mitigation solutions — including concrete breakwaters — damage due to storm surge and flooding continues to devastate coastal areas around the world. In response to these threats, DARPA has launched the Reefense program to develop self-healing, hybrid biological, and engineered reef-mimicking structures to protect civilian and DoD infrastructure, personnel by mitigating damage related to coastal flooding, erosion and storm surge.

  • Preparing National Security Officials for the Challenges of AI

    Artificial intelligence (AI) is one of several rapidly emerging technologies that promise to disrupt not only multiple sectors of the U.S. economy but also the manner in which the U.S. government carries out its foundational responsibility to protect national security consistent with the rule of law and constitutional values. Steve Bunnell writes that “The United States’ national security apparatus is not known for nimbleness, nor is the law that governs it. When it comes to AI, the risk is not just that our generals will fight tomorrow’s war with yesterday’s strategy but also that the United States will lack the legal and policy guardrails that are essential to a lawful, accountable, and ethical protection of the nation’s security.”

  • Declining Water Reserves in California May Cut Hydropower Use in Half This Summer

    As summer approaches, it’s clear that the heavy rains which pummeled California in late 2021 did little to shore up the state’s water reserves, and analysts are warning that the state’s hydroelectric supplies — a cheap source of clean power in California — are once again at risk.

  • Critical Global Water Questions

    Recent intense heatwaves in India and widespread U.S. droughts have highlighted the need for a global approach to tackling chronic water shortages. The problem is that most governments are not equipped to deal with these challenges of water scarcity, sanitation and climate dynamics.

  • Preparing Communities for Dam-Related Emergencies

    There are more than 90,000 dams registered in the U.S. National Inventory of Dams across the country. But we rarely hear about them until the worst happens: one of them fails. Extreme weather events and the aging dam infrastructure are making dam-related emergency action plans more critical than ever.

  • Cybersecurity Tools to Protect Solar, Wind Power on the Grid

    Solar panels and wind turbines are projected to produce 44% of America’s electricity by 2050, but they present cybersecurity challenges. They have sensors, controllers, actuators or inverters which are directly or indirectly connected to the internet using insecure connectivity to legacy electric grid systems. They have complex physics. They’re subject to advanced persistent threats. And there will be more and more of them going online.

  • Add-on Benefits of Natural Defenses Against Sea-Level Rise

    Researchers modeled how investing in environmental conservation and protection can help San Mateo County, California, adapt to rising seas. The findings provide incentives for policymakers to prioritize nature-based approaches when planning for sea-level rise.

  • Protecting Nuclear Waste Containers from Metal-Corroding Microbes

    Canada has about three million bundles of used nuclear fuel, which contain the solid uranium that powers nuclear reactors. They’re stored in above-ground containers at seven facilities across the country, with 90,000 added every year. The containers only last about 50 to 100 years, but used nuclear fuel must be stored for one million years before its radiation levels return to that of naturally occurring uranium ore. Canada is getting closer to moving all its spent nuclear fuel to a single facility, and encasing each fuel container in bentonite clay, and researchers are studying whether that clay could support microbial life – which could eat away at the metal containers.

  • Sustainable Solution for Oil, Gas Wastewater

    As demand for new energy sources grows, the wastewater co-produced alongside oil and gas (produced water) shows no signs of slowing down: The current volume of wastewater - the result of water forced underground to fracture rock and release the deposits - is estimated at 250 million barrels per day, compared to 80 million barrels per day of oil. Engineers are developing a new way to clean the produced water for reuse, and it’s already being tested in Pennsylvania, Texas and North Dakota.

  • The Risk of Drinking Contaminated Water During Flooding

    In addition to causing property damage and psychological impacts, flooding can pose a significant health risk, particularly due to contamination of drinking water sources. Researchers are a decision-making tool to estimate the risk of water contamination in flooded areas.

  • Groundwater Depletion Causes California Farmland to Sink

    A new study simulates 65 years of land subsidence, or sinking, caused by groundwater depletion in California’s San Joaquin Valley. The results suggest significant sinking may continue for centuries after water levels stop declining but could slow within a few years if aquifers recover.

  • U.S. Elevates Water Security as Foreign Policy Priority

    The White House on Wednesday announced the an Action Plan on Global Water Security, drawing direct links between water scarcity and national security and elevating water security to a core foreign policy priority for the first time.
