Researchers Simulate Defense of the Earth
Sixty-six million years ago, a giant asteroid impact on the Earth likely caused the extinction of the dinosaurs. Currently no known asteroid poses an immediate threat. But if one day a large asteroid were to be discovered on a collision course with Earth, it might have to be deflected from its trajectory to prevent catastrophic consequences.

Sea Levels Rise and Floods Intensify, So Governments Consider Managed Retreat
As climate changes, rising sea levels and disastrous flooding are becoming ever more common, and they could force billions to move during the next decades. Instead of trying to prolong the inevitable by building sea walls, importing sand to build protective dunes and berms, planting mangrove, and raising structures on stilts, some communities are already adapting: They are developing plans to move away from vulnerable areas to higher ground inland.

Soon: Fire-Safe, Recyclable Lithium-Metal Batteries
To power our increasingly electrified society, energy storage technology must evolve and adapt to meet the growing demand. Lithium-ion batteries, already essential to myriad technology, will require dramatic improvements in high-energy density, safety, temperature resilience, and environmental sustainability in order to provide the type of emission-free future that so many envision. Such improvements are here.

Announcing the Electric Resilience Toolkit
A new Electric Resilience Toolkit aims to support policymakers and stakeholders working on issues around electric sector regulation and climate resilience planning. Such planning is essential to ensure electricity infrastructure is designed and operated in a way that accounts for the impacts of climate change—impacts that are already being felt and which will only intensify in coming years.

The Administration’s New Vision for the National Flood Insurance Program
The Biden administration is proposing a major overhaul to the National Flood Insurance Program, or NFIP — the main source of insurance for homeowners who are required to or choose to obtain coverage for flooding. The administration’s flood insurance reforms could improve transparency — and make some Americans more vulnerable.

Assessing the Environmental Impact of Nuclear Power Generation
Nuclear power is considered a panacea for the environmental degradation caused by fossil fuels. However, its environmental impact and natural resource use need to be assessed. Researchers make a life cycle assessment of resource use in nuclear power generation from uranium.

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.

Concerns About Extremists Targeting U.S. Power Stations
Attacks on four power stations in Washington State over the weekend added to concerns of a possible nationwide campaign by far-right extremists to stir fears and spark civil conflict. Violent extremists “have developed credible, specific plans to attack electricity infrastructure since at least 2020, identifying the electric grid as a particularly attractive target given its interdependency with other infrastructure sectors,” the DHS said in a January.
Using Blockchain to Increase Electric Grid Resiliency
Blockchain is best known for securing digital currency payments, but researchers are using it to track a different kind of exchange: It’s the first time blockchain has ever been used to validate communication among devices on the electric grid.
Hydrogen Changing Power Dynamics in Energy Sector
As the EU tries to finalize its hydrogen rules, Asian countries are moving fast to secure deliveries and the US is committing money to set up local supply chains. Can the Middle East collaborate with both continents?
The Cold War Legacy Lurking in U.S. Groundwater
In America’s rush to build the nuclear arsenal that won the Cold War, safety was sacrificed for speed. ProPublica has cataloged cleanup efforts at the 50-plus sites where uranium was processed to fuel the nation’s nuclear arsenal. Even after regulators say cleanup is complete, polluted water and sickness are often left behind.
