• The Threat of an Electromagnetic Attack

    When much of Venezuela was plunged into darkness after a massive blackout this week, President Nicolás Maduro blamed the power outage on an “electromagnetic attack” carried out by the U.S. The claim was met with skepticism, but Maduro’s claim has raised questions over what exactly is an electromagnetic attack, how likely is it to occur and what impact could it have.

  • Truth and Fearmongering: Yucca Mountain Nuclear Waste Repository

    Is it a good idea to store 77,000 tons of highly radioactive nuclear waste in a repository in Nevada’s Yucca Mountain? Many Nevada politicians say it is a bad idea, but scientists argue that the facts do not support the fears these politicians stoke. These scientists say that Colorado, whose surface rock contains about a billion tons of uranium, should have much more to worry about than Nevada. One scientist says: “If the Yucca Mountain facility were at full capacity and all the waste leaked out of its glass containment immediately and managed to reach groundwater, the danger would still be 20 times less than that currently posed by natural uranium leaching into the Colorado River.”

  • Coping with Climate Change with Forecast-Based Aid

    Traditionally, disaster victims have received assistance after trouble hits. If a region is flooded, say, people in the area may get aid to rebuild. But a new approach to humanitarian giving is flipping the script and offering help in advance of disaster, using in-depth weather forecasting and risk analysis to predict future victims.

  • Glaciers May Be Melting Faster Than We Expected

    From Alaska to Antarctica, thousands of glaciers flow over the land and out to the ocean. These tidewater glaciers are rapidly retreating and melting, like much of Earth’s ice, continually adding to rising sea levels. But to date, scientists have struggled to pinpoint where on the face of a glacier’s terminus the most intense melting occurs—and exactly how fast it is happening. Until now.

  • Russia Targeted Election Infrastructure in All 50 States in 2016: Senate Intel Report

    On Thursday the Senate Intelligence Committee releases the first volume in the Committee’s bipartisan investigation into Russia’s attempts to interfere with the 2016 U.S. elections, dealing with Russia’s attacks on the U.S. election infrastructure. The Committee found that Russia targeted election systems in all 50 states in 2016. In the majority of cases, Russia’s attacks went undetected by the states and federal officials at the time. The report suggested that the Russian efforts in 2016 might have been cataloging options “for use at a later date” — a possibility that officials of the National Security Agency, DHS, and the FBI said was their biggest worry.

  • Cyber Threats from the U.S. and Russia Are Now Focusing on Civilian Infrastructure

    Cyber confrontation between the United States and Russia is increasingly turning to critical civilian infrastructure, particularly power grids, judging from recent press reports. The typically furtive conflict went public last month, when the New York Times reported U.S. Cyber Command’s shift to a more offensive and aggressive approach in targeting Russia’s electric power grid. Although both sides have been targeting each other’s infrastructure since at least 2012, according to the Times article, the aggression and scope of these operations now seems unprecedented.

  • Johannesburg Power Company Crippled by Ransomware Attack

    City Power, the company supplying Johannesburg, South Africa’s economic hub, with electricity, has been attacked by a ransomware virus. The virus has “encrypted all our databases” representatives of the company said. Some of the company’s services have been crippled; the company said it may not be able to respond to a blackout; and more and more residents complain of loss of power. Johannesburg is not the first municipality to have its network infected by ransomware.

  • The Sea Is Rising. Can You Save Your Town?

    That headline is also your mission in The Ocean Game, the LA Times’ deceptively simple online simulation of city governance in the face of climate change. The game accompanies an in-depth look at how various California coastal communities are responding to the effects of rising seas caused by global warming. California may not be the most vulnerable part of the world that will experience the effects of sea-level rise in the coming decades, but the problems it faces are not at all trivial.

  • “A High Risk to Their Users”: An Analysis of Huawei Devices’ Security Vulnerabilities

    Western intelligence services have long suspected that the Chinese communication giant Huawei was a tool of China’s powerful intelligence services. An analysis of the state of security of Huawei’s gear and equipment has found serious security flaws and vulnerabilities. This is important, because even if we take Huawei’s implausible denials of any relationship to Chinese government at face value, the low quality of security of Huawei’s equipment would allow the Chinese government, and other state actors, to compromise the vulnerabilities of networks built with Huawei’s components. Our “analysis shows that Huawei devices quantitatively pose a high risk to their users,” the report says.

  • Developing ‘Smart City’ Floodwater Management

    In a world of smart watches, smart homes and smart appliances that monitor their environments to keep users safe and informed, can whole cities be smarter? Short answer: Probably, using cutting-edge information technologies to keep citizens and property safer.

  • Q&A: How Ridgecrest Earthquakes Helped Scientists with ShakeAlert

    U.S. Geological Survey geophysicist Sarah Minson was in the thick of efforts to develop an earthquake warning system in California when a series of major temblors struck the sparsely populated community of Ridgecrest in the Mojave Desert this summer. The largest, a magnitude 7.1 quake on July 5, was the biggest to hit the state in decades. The Mercury News asked her about her work — and how this month’s big quakes is helping scientists refine California’s fledgling earthquake alert system.

  • What If a Hurricane Pushed a Surge up an Already High Mississippi River? No One Is Certain.

    The Mississippi River has always been the lifeblood of New Orleans. It’s the reason for the city’s existence, and an awe-inspiring if sometimes forgotten feature of its landscape. One thing it hasn’t been, at least in recent memory, is a threat. That is, until this month, when wary residents caught a glimpse of the old Mississippi, a face of the river that’s been hidden since it was almost completely caged by man nearly a century ago. The compliant river had become a beast scaling its walls.

  • Americans Focus on Responding to Earthquake Damage, Not Preventing It, Because They’re Unaware of Their Risk

    On July 4 and 5, two major earthquakes, followed by several thousand smaller ones, struck Southern California. Their size and the damage they caused captured attention around the country. What tends to get much less notice from the public is what can be done to prevent catastrophic damage from big quakes.

  • Innovative ways to repair and construct bridges, roadways

    A 2016 American Society of Civil Engineers Infrastructure assessment reported that more than 9 percent of the nation’s bridges are considered structurally deficient and 1 out of every 5 miles of highway pavement is in poor condition. Researchers will develop innovative techniques to repair and construct bridges and roadways through a new U.S. Department of Transportation-funded research center.

  • New Sensor Improves Earthquake Response Efforts

    The recent massive southern California earthquakes shut down Ridgecrest Regional Hospital throughout the 4 July holiday weekend while the tiny town of Ridgecrest assessed the damages. Researchers developed a new optical sensor which could speed up the time it takes to evaluate whether critical buildings like these are safe to occupy shortly after a major earthquake.
