• New model predicts landslides caused by earthquakes

    Landslides are the third-largest contributor to earthquake deaths, after building collapse and tsunamis. From 2004 to 2010, earthquake-induced landslides caused an estimated 47,000 deaths. Researchers have developed a model which can help experts address such risks by estimating the likelihood of landslides that will be caused by earthquakes anywhere in the world.

  • Celestial hazards: Twenty years of planetary defense

    NASA’s Center for Near-Earth Object Studies was established in 1998 to fulfill a 1998 Congressional request to detect and catalogue at least 90 percent of all NEOs larger than one kilometer in size (roughly two-thirds of a mile) within 10 years. In 2005, Congress established a new, much more ambitious goal for the NEO Observations Program — to discover 90 percent of the NEOs down to the much smaller size of 450 feet (140 meters), and to do so by the year 2020. There are now over 18,000 known NEOs and the discovery rate averages about 40 per week.

  • Report: Russian hackers came close to causing U.S. blackouts last year

    DHS has warned utilities that Russian government hackers accessed the U.S. electric grid control systems in 2016 and 2017, and could have, at the time of their choosing, caused blackouts across the United States. “They got to the point where they could have thrown switches” and disrupted power flows, said Jonathan Homer, chief of industrial-control-system analysis for DHS. DHS is gathering evidence on the Russian government’s attempt to automate these attacks on the U.S. grid.

  • DOJ releases Cyber-Digital Task Force report

    The Department of Justice last Thursday released a report produced by the Attorney General’s Cyber-Digital Task Force. The report provides a comprehensive assessment of the cyber-enabled threats confronting the United States and details the ways in which the DOJ combats those threats. The first section of the report focuses on what DOJ describes as “the most pressing cyber-enabled threats confronting the United States: the threat posed by malign foreign influence operations.”

  • Using satellites to measure vital underground water resources

    The availability of water from underground aquifers is vital to the basic needs of more than 1.5 billion people worldwide. In recent decades, however, the over-pumping of groundwater, combined with drought, has caused some aquifers to permanently lose their essential storage capacity. Scientists are using the latest space technology to measure this precious natural resource.

  • Buried internet infrastructure at risk as sea levels rise

    Thousands of miles of buried fiber optic cable in densely populated coastal regions of the United States may soon be inundated by rising seas, according to a new study. The study, presented at a meeting of internet network researchers, portrays critical communications infrastructure that could be submerged by rising seas in as soon as fifteen years. “Most of the damage that’s going to be done in the next 100 years will be done sooner than later,” says Ban authority on the “physical internet.” “That surprised us. The expectation was that we’d have 50 years to plan for it. We don’t have 50 years.”

  • Smarter, safer bridges with Sandia sensors

    In 2016, more than 54,000 bridges in the U.S. were classified as “structurally deficient” by the Federal Highway Administration’s National Bridge Inventory. This means about 9 percent of U.S. bridges need regular monitoring. Researchers outfitted a U.S. bridge with a network of eight real-time sensors able to alert maintenance engineers when they detect a crack or when a crack reaches a length that requires repair.

  • Nuclear waste: The cost to Americans is in the billions

    Since the Manhattan Project officially began in 1942, the United States has faced ever-increasing stores of nuclear waste. Stanford’s Rodney Ewing says that the U.S. failure to implement a permanent solution for nuclear waste storage and disposal is costing Americans billions of dollars a year.

  • Rising sea levels could cost the world $14 trillion a year by 2100

    Failure to meet the United Nations’ 2ºC warming limits will lead to sea level rise and dire global economic consequences, new research has warned. The study calculated that flooding from rising sea levels could cost $14 trillion worldwide annually by 2100, if the target of holding global temperatures below 2ºC above pre-industrial levels is missed.

  • Looking to millennials for new nuclear energy inspiration, conversation

    The torch of nuclear energy may be passing to a new generation: On 15 June, Idaho National Laboratory hosted a Millennial Nuclear Caucus, the latest to be held across the country since October 2017. The majority of participants were young interns and researchers from the lab, but young people from across the community were invited to attend.

  • Making nuclear energy safer and more affordable

    Galvanized by the Fukushima Daiichi nuclear disasters, MIT Ph.D. student Xingang Zhao envisions a future with safe, efficient nuclear power. Pressurized water reactors, which generate the majority of the electricity derived from nuclear power worldwide, are operating at parameters that are too conservative, compromising efficiency and energy output. Zhao suspects that under some scenarios traditional models that calculate critical heat flux place it too low, meaning that the current nuclear reactor fleets are operating well under capacity.

  • Sea level rise and coastal development: Science speaks directly to business

    If you are an investor or a developer with an interest in coastal properties, you are being bombarded with evidence of climate change in the form of sea level rise and its consequences. In the academic community, many interested in the business of coastal development have begun to take into account information from climate scientists and have expressed frustration that government regulators are not doing so.

  • Greenpeace France crashes drone at French nuclear plant

    Greenpeace France said Tuesday it had flown the drone – remotely piloted by one of its activists – over Bugey nuclear plant near Lyon, France. The pilot then crashed the Superman-shaped drone against the wall of the facility’s spent-fuel pool building. This is not the first stunt by the environmental group at a French nuclear plant. The groups says it aims to expose the vulnerabilities of nuclear plants to terrorist attacks and accidents.

  • 3 reasons why the U.S. is vulnerable to big disasters

    During the 2017 disaster season, three severe hurricanes devastated large parts of the U.S. The quick succession of major disasters made it obvious that such large-scale emergencies can be a strain, even in one of the world’s richest countries. Why do some countries better withstand and respond to disasters? The factors are many and diverse, but three major ones stand out because they are within the grasp of the federal and local governments: where and how cities grow; how easily households can access critical services during disaster; and the reliability of the supply chains for critical goods. For all three of these factors, the U.S. is heading in the wrong direction. In many ways, Americans are becoming more vulnerable by the day.

  • Warming climate would make wildfire-prone homes uninsurable

    Nine months after the October 2017destructive Tubbs Fire in Sonoma County, the process of reconstruction has begun. Experts question the prudence of rebuilding in some of the burnt-out areas in light of existing fire hazard and predictions of how the warming climate will fuel more frequent and severe wildfires in the western United States.
