• Owners of unprotected coastal homes don’t rush to retrofit

    Many coastal homes have significant structural vulnerabilities that leave homeowners and their homes largely unprotected from storms. Additionally, the majority of coastal homeowners have little to no intention of reducing these structural vulnerabilities, even though they live in areas frequently affected by damaging hurricanes and flooding.

  • Driving force of volcanic super-hazards uncovered

    Volcanologists have discovered the driving force behind superheated gas-and-ash clouds from volcanic eruptions, which may help save lives and infrastructure around the globe. Endangering 500 million people worldwide, pyroclastic density currents (or pyroclastic flows) are the most common and lethal volcanic threat, causing 50 percent of fatalities caused  by volcanic activity.

  • Predicting impacts of extreme events on grids

    A new, free, open-source software reliably predicts how damage from hurricanes, ice storms, earthquakes, and other extreme events will restrict power delivery from utility grids. The Severe Contingency Solver for Electric Power Transmission is the only software available—commercially or open-source—that reliably supports analysis of extreme events that cause widespread damage.

  • A how-to guide for climate-proof cities

    Traditionally, Maurepas Swamp serves as a natural barrier against flooding that threatens New Orleans each year. Native flora soaks up the rainfall, spreading it across a network of cypress roots and cattail. But centuries of logging and canal construction have drastically altered the swamp’s ecological composition. The Mississippi levee system compounded the issue, isolating the swamp from vital sources of fresh water and nutrients. Flooded with saltwater, much of the existing cypress withered and died. Young trees, now, are few and scattered.

  • Melting glaciers causing sea levels to rise at ever faster pace

    Melting ice sheets in Greenland and the Antarctic as well as ice melt from glaciers all over the world are causing sea levels to rise. Glaciers alone lost more than 9,000 billion tons of ice since 1961, raising water levels by 27 millimeters.

  • Nagging security concerns over using Huawei’s tech in Europe

    New report urges NATO members to look to emulate Britain, which created an entire government office to scrutinize Huawei’s products for security problems.

  • Bigger than Huawei: U.S. broadens scrutiny of Chinese technology

    A flurry of seemingly disconnected actions by the U.S. government to curb the involvement of Chinese technology firms in the U.S. economy over the past year reflects the Trump administration’s intensifying concern that those firms could — now or in the future — abet espionage by Beijing’s intelligence services.

  • AI automatically detects disturbances in power supply grids

    The grid is changing as the big, centralized providers of the past are replaced by smaller, distributed suppliers. Keeping such complex networks running stable requires high-resolution sensor technology – AI provides a way to make accurate predictions and automatically detect any disturbances or anomalies in real time.

  • British oversight body: Security flaws in Huawei 5G networks

    A British oversight board has slammed the Chinese telecom giant Huawei for software security flaws. The report, however, stopped short of blaming Chinese intelligence agencies for the engineering defects. The United States is concerned that Huawei is a front for the Chinese intelligence services, and that rolling out Huawei’s 5G system in Europe would open the door for Chinese spying or sabotage.

  • California hospitals to pay billions for seismic safety upgrades

    California hospitals would need to make substantial investments—between $34 billion and $143 billion statewide—to meet 2030 state seismic safety standards, according to a new report.

  • Rapidly melting tall ice-cliffs may trigger faster sea-level rise

    Glaciers that drain ice sheets such as Antarctica or Greenland often flow into the ocean, ending in near-vertical cliffs. As the glacier flows into the sea, chunks of the ice break off in calving events. Although much calving occurs when the ocean melts the front of the ice, and ice cliff above falls down, a new study presents another method of calving: slumping. And this process could break off much larger chunks of ice at a quicker rate.

  • Geothermal plant caused South Korea’ 2017 tremor

    A rare earthquake in South Korea was triggered by the country’s first experimental geothermal power plant, government officials said Wednesday. The southeastern port city of Pohang was rattled by a 5.4-magnitude earthquake in November 2017— the second-most powerful tremor ever in the normally seismically stable South.

  • Mitigating impact of rising seas, storms along California’s coast

    New coastal modeling research presents state, federal, and commercial entities with varying storm and sea level-rise scenarios to assist with planning for future infrastructure and mitigation needs along the California coast.

  • A new way to sense earthquakes could improve early warning systems

    Every year earthquakes worldwide claim hundreds or even thousands of lives. Forewarning allows people to head for safety and a matter of seconds could spell the difference between life and death. Researchers demonstrate a new earthquake detection method — their technique exploits subtle telltale gravitational signals traveling ahead of the tremors. Future research could boost early warning systems.

  • China's Huawei sues U.S. government over ban

    Chinese tech giant Huawei has sued the U.S. government, arguing that legislation Congress passed last year that restricts its business in the United States is “unconstitutional.” The case, which analysts see more as a public relations move, is but the latest in an intensifying effort by the telecommunications company to fight U.S. security concerns, which Huawei argues are unfair and unfounded.
