• Containing a Nuclear Accident with Ground-up Minerals

    Researchers at Sandia National Laboratories are developing a promising new way to prevent the spread of radioactive contamination and contain the hot molten mass that develops within a nuclear reactor during a catastrophic accident. A team of scientists discovered and patented a process for injecting sand-like minerals into the core of a nuclear reactor during an accident to contain and slow down the progression of a meltdown.

  • A Meltdown in Nuclear Security

    A commando raid on a nuclear power plant seems the stuff of Hollywood. So why are nuclear security experts so worried? It ranks among the worst-case scenarios for a nuclear power plant: an all-out assault or stealth infiltration by well-trained, heavily armed attackers bent on triggering a nuclear blast, sparking a nuclear meltdown or stealing radioactive material. Under pressure from a cash-strapped nuclear energy industry increasingly eager to slash costs, the commission in a little-noticed vote in October 2018 halved the number of force-on-force exercises conducted at each plant every cycle. Four months later, it announced it would overhaul how the exercises are evaluated to ensure that no plant would ever receive more than the mildest rebuke from regulators – even when the commandos set off a simulated nuclear disaster that, if real, would render vast swaths of the U.S. uninhabitable. Nuclear security experts, consultants, law enforcement veterans and former NRC commissioners are nothing short of alarmed. “You can’t afford to be wrong once,” says one expert.

  • Designing the Coastal City of the Future

    Boston is situated along the Gulf of Maine, which is warming faster than 99 percent of the ocean due, in part, to changing sea patterns from melting ice in Greenland and the Arctic Ocean. Coupled with increased heat and precipitation, the rising sea level is threatening the low-lying city, much of which was built on landfill over the past 300 years along a 50-square-mile harbor. To save the 685,000-person city, the local government is calling on architects to help implement one of the most ambitious municipal resiliency plans in the United States: Climate Ready Boston. Launched in 2016 by Mayor Martin J. Walsh, Climate Ready Boston is an initiative to prepare the city for the long-term impacts of climate change.

  • Ecosystem Investments Could Minimize Storm Damage

    A new study provides information on how to invest in natural coastal ecosystems that the Bahamian government, community leaders and development banks are applying in post-disaster recovery and future storm preparation in the Bahamas.

  • 250,000 Cubic Meters of Ice in Danger of Breaking Off Europe's Mont Blanc

    Highlighting concerns about global warming, Italian authorities now fear that part of the glacier on Mont Blanc, Europe’s highest mountain, is at risk of collapse. Experts have been monitoring the Planpicieux glacier on Mont Blanc for some time and concerns have been mounting in Italy that a section of the glacier is at risk of collapsing. Mayors of the picturesque ski towns in the area have been taking civil defense measures, including plans for evacuation on a short notice.

  • Stopping an “Internet of Things” Attack from Bringing Down the Power Grid

    Last year, Princeton researchers identified a disturbing security flaw in which hackers could someday exploit internet-connected appliances to wreak havoc on the electrical grid. Now, the same research team has released algorithms to make the grid more resilient to such attacks. The algorithms could stop an internet of things attack from bringing down the power grid.

  • Can Going Nuclear Combat Climate Change?

    To mitigate climate change, the proportion of low-carbon electricity generation must increase from today’s 36 percent to 85 percent by 2040, the International Energy Agency (IEA) says. IEA and other advocates argue that nuclear power could help fill this gap. However, barriers to a nuclear energy renaissance include safety concerns, aging reactors and high costs for new ones.

  • NYC Building a Seawall to Protect City from Rising Seas

    On Staten Island, the section of New York City which suffered most of Superstorm Sandy’s devastation, most of the homes destroyed by the storm still sit empty. City engineers have concluded that there was no point fixing and rehabilitating these homes until other measures are taken to protect the Staten Island from the next devastating storms. And climate change will only make these storms more frequent and more intense. These other measures are now underway.

  • Global Warming Has “Profound Consequences” for Oceans, Cryosphere

    The ocean and the cryosphere – the frozen parts of the planet – play a critical role for life on Earth. A total of 670 million people in high mountain regions and 680 million people in low-lying coastal zones depend directly on these systems. Four million people live permanently in the Arctic region, and small island developing states are home to 65 million people. Global warming has profound consequences for these ecosystems: The ocean is warmer, more acidic and less productive; melting glaciers and ice sheets are causing sea level rise; and coastal extreme events are becoming more severe.

  • Making the Internet Faster, More Secure

    A collaborative effort aims to create a nationwide research infrastructure that will enable the computer science and networking community to develop and test novel architectures that could yield a faster, more secure internet. Dubbed “FABRIC,” the four-year, $20 million project is intended to support exploratory research, at scale, in computer networking, distributed computing systems, and next-generation applications.

  • California Wildfires Can Impact Water Availability

    In recent years, wildfires in the western United States have occurred with increasing frequency and scale. Climate change scenarios in California predict prolonged periods of drought with potential for conditions even more amenable to wildfires. The Sierra Nevada Mountains provide up to 70 percent of the state’s water resources, yet there is little known on how wildfires will impact water resources in the future.

  • R&D, not Greenland, Can Solve Our Rare Earth Problem

    While President Trump’s proposal to buy Greenland lit up social media feeds and left many scratching their heads, people who work on rare earth elements were not surprised. Greenland has rare earth elements, and currently most are mined in China. Julie Michelle Klinger and Roger Turner write that instead of periodically reviving rare earth scarcity myths to stoke anti-China sentiment or justify outlandish ideas like buying Greenland or pulverizing the moon, we can invest in several areas where people are already working. “Opening more mines like it’s 1590, buying territories like it’s 1867, or blasting asteroids like we’re in a 1950s sci-fi flick won’t solve the problem, because the problem is not a shortage of unrefined ores. Instead, smart R&D investments will bring our production, consumption and disposal practices into the 21st century. This means reducing waste, increasing recycling and repair, and cleaning up the dirtiest and most dangerous aspects of the supply chain.”

  • This Technology Replaces Coal Power with Wood Power

    A new technology makes it possible to replace coal with eco-friendly wood pellets. As soon as the world stops fueling its power plants with coal, Norwegian technology company Arbaflame is ready to pick up the baton.

  • The Myth of U.S. Energy Independence Has Gone Up in Smoke

    In response to the massive attack on Saudi Arabia’s oil infrastructure this weekend, U.S. President Donald Trump has trumpeted that America’s new oil abundance cushions the disruption and boosts strategic stocks, arguing that building more oil pipelines will help protect Americans from oil price shocks. Jason Bordoff writes Foreign Policy that in reality, the attack on Abqaiq, the world’s most critical oil facility, is a stark reminder that the United States is not energy independent, nor can it go it alone when it comes to diplomacy in the world’s most critical oil-producing region.

  • If U.S. Claims of How the Saudi Oil Attack Went Down Are True, Then the Failure to Prevent It Is a Huge Embarrassment

    It has yet to be definitively established how the massively disruptive attacks this past weekend on a crucial Saudi oil facility took place. The version of events being advanced by U.S. officials, however — that most of the damage was from cruise missiles launched from Iran — raises the embarrassing question of why the U.S. military was unable to do anything about it. the airspace around Iran and Saudi Arabia is some of the best-defended and most intensively monitored on earth, thanks to the decades-long buildup of U.S. assets there. But on Saturday those defenses failed to prevent what U.S. officials have said were at least 17 separate strikes. Based on information made public about the strikes, defense insiders were left wondering how the U.S. military had fared so poorly in one of its primary missions in the region.
