As California Attempts a “Managed Retreat,” Coastal Homeowners Sue to Stay
“Managed retreat” is a climate adaptation policy that calls for relocating and removing coastal structures rather than protecting them where they are. Experts say managed retreat is an important last-resort option for adapting to climate change, but California’s early attempts to implement the policy have provoked a backlash from homeowners and politicians.

How Molten Salt Could Be the Lifeblood of Tomorrow’s Nuclear Energy
Molten salt has caught the eye of the nuclear industry as an ideal working fluid for reactor cooling, energy transfer, fueling and fission product absorption. Many of the salts being considered are inexpensive, nontoxic, and easily transportable – and table salt is one of the constituents many reactor developers are choosing to use.

Why Insurance Companies Are Pulling Out of California and Florida, and How to Fix Some of the Underlying Problems
When the nation’s No. 1 and No. 4 property and casualty insurance companies – State Farm and Allstate – confirmed that they would stop issuing new home insurance policies in California, it may have been a shock but shouldn’t have been a surprise. It’s a trend Florida and other hurricane- and flood-prone states know well. Insurers have been retreating from high-risk, high-loss markets for years after catastrophic events. As losses from natural hazards steadily increase, research shows it’s not a question of if insurance will become unavailable or unaffordable in high-risk areas – it’s a question of when.

China’s Push for Science and Technology Collaboration with BRI Countries
China is aiming to make science and technology (S&T) cooperation a significant component of the Belt and Road Initiative (BRI). There are complaints over Chinese approach of sharing data and protection of intellectual property. Maintaining accountability and transparency is vital for progress and can ensure win-win cooperation with member countries of BRI. A key fundamental is to uphold the principle of “open science,” making scientific process more transparent, inclusive and democratic.

Boosting Supply Chains by Recovering Valuable Materials from Water
Promoting national security and economic competitiveness will require America’s researchers to find new ways to obtain the materials that we need for many technologies. Traditional mining is fraught with challenges, while water, from the oceans to geothermal brines, is an underexplored resource for providing various materials.

Human-Caused Climate Change at the Center of Recent California Wildfires
Summer wildfire seasons in California routinely break records. The average summer burn area in forests in northern and central portions of the state have increased fivefold between 1996 and 2021 compared to between 1971 and 1995. In a new study, scientist and collaborators shows that nearly all the recent increase in summer wildfire burned area is attributable to human-caused (anthropogenic) climate change.

What If China Really Did Develop COVID as a Bioweapon? Here Are the Issues Involved
A recent report by the Sunday Times claims the newspaper has seen evidence that China was developing dangerous coronaviruses in collaboration with the Chinese military for the alleged purposes of biowarfare. This research program was the likely source of the pandemic, the report asserts.So, what could the rest of the world do about these new allegations – if anything? There is no easy answer, because, given the nature of biological research, we may never be able to reach a conclusive answer about the bioweapon question.

Climate Change Is a National Security Risk
Climate change is affecting practically everything on Earth, from natural systems to human endeavors. National security is no exception. The U.S. Defense Department recognizes that climate change is a “threat multiplier” as it exacerbates existing environmental stresses and security risks.
Scientists Map Loss of Groundwater Storage Around the World
Global water resources are stretched by climate change and human population growth, and farms and cities are increasingly turning to groundwater to fill their needs. Unfortunately, the pumping of groundwater can cause the ground surface above to sink. A new study maps, for the first time, the permanent loss of aquifer storage capacity occurring globally.
