• Floods will cost the U.K. billions, but AI can help make sewers the first defense

    The U.K. will need to spend £1 billion a year on flood management to avoid the worst consequences of climate change, according to the national Environment Agency. Coastal defenses – including sea walls, buffer areas and evacuation plans – can help to protect towns and cities against flooding from storm surges. But inland flooding caused by excess rainwater requires more nuanced solutions. Today, artificial intelligence (AI) can use data to help make decisions about how water should flow in and around human settlements, to avoid the worst effects of flooding.

  • As floods increase, cities like Detroit are looking to green stormwater infrastructure

    Urban sprawl meant paving over grasslands and wetlands, making it so water is unable to soak into the ground. Today, that impervious development, coupled with the more intense storms brought by climate change, is making flooding a major issue for many cities. Urban areas are looking for better ways to manage runoff.

  • Better earthquake protection for buildings

    Researchers examine how buildings with externally bonded fiber-reinforced polymer composite retrofits withstood the 30 November 2018 magnitude 7.1 earthquake in Alaska. By assessing how these buildings held up, the researchers hope to help engineers construct buildings that stand up to natural disasters.

  • As planet warms, even little precipitation may disrupt road networks

    A new computer model shows that as more rain falls on a warming planet, it may not take a downpour to cause widespread disruption of road networks. The model combined data on road networks with the hills and valleys of topography to reveal “tipping points” at which even small localized increases in rain cause widespread road outages.

  • U.S. official: Executive order not needed to ban Huawei in U.S. 5G networks

    “We have grave concerns about the Chinese vendors because they can be compelled by the National Intelligence Law in China as well as other laws in China to take actions that would not be in the interests of the citizens of other countries around the world. Those networks could be disrupted or their data could be taken and be used for purposes that would not be consistent with fundamental human rights in those countries,” says Robert Strayer, deputy assistant secretary of state for cyber and international communications and information policy.

  • Electricity grid cybersecurity will be expensive – who will pay, and how much?

    Russia, China, North Korea and Iran are capable of hacking into the computers that control the U.S. electricity grid. Protecting the grid from hacking would cost tens of billions of dollars. The electricity customers will likely foot most of the bill.

  • Signals from distant space could help secure electric substations

    Side channel signals and bolts of lightning from distant storms could one day help prevent hackers from sabotaging electric power substations and other critical infrastructure.

  • Revisions to National Seismic Hazard model proposed

    As many as 34 million people in the U.S.(about one in nine people) are expected to experience a strong level of shaking at least once in their lifetimes. Experts say that the U.S. National Seismic Hazard Model (NSHM) should be revised to reflect the greater likelihood of ground shaking across many locations in the central and eastern United States.

  • A Seattle quake may cause more damage than expected to reinforced concrete

    Using ground motions generated for a range of simulated magnitude 9 earthquakes in the Pacific Northwest, researchers are testing how well reinforced concrete walls might stand up under such seismic events. The walls may not fare so well, especially within the city of Seattle, the researchers say.

  • Blinded and confused: Security vulnerabilities in “smart home” IoT devices

    Researchers have identified design flaws in “smart home” Internet-of-Things (IoT) devices that allow third parties to prevent devices from sharing information. The flaws can be used to prevent security systems from signaling that there has been a break-in or uploading video of intruders.

  • The why, how, where, and what of earthquake early warning

    Earlier this year, Los Angeles became one of the first cities in the country to roll out ShakeAlert – a dedicated earthquake early warning system. Advanced warning of an earthquake has long been a goal for everyone from seismologists to local governments. Especially in cities like Los Angeles, located along the notorious San Andreas fault. But what about cities like Seattle?

  • Fracking Linked to earthquakes in the Central and Eastern United States

    Small earthquakes in Ohio, Pennsylvania, West Virginia, Oklahoma and Texas can be linked to hydraulic fracturing wells in those regions, according to researchers. While relatively rare compared to earthquakes caused by wastewater disposal in oil and gas fields in the central United States, the researchers  have identified more than 600 small earthquakes (between magnitude 2.0 and 3.8) in these states.

  • “Metamaterials” may mitigate earthquake damage

    In the past decade scientists have been experimenting with metamaterials, artificial materials designed with periodic internal structures to give them properties not found in natural materials. Some of these materials can control waves propagating through them, filtering sound or deflecting light so that an object appears “cloaked” or invisible, for instance. Could this same principle be applied to controlling seismic waves?

  • California: Coastal impacts of climate change

    The United States Geological Survey (USGS) says that sea-level rise is going to wreak widespread destruction on California’s coastal communities, unless these communities take urgent action to mitigate to risks. “Even the storms today have significant risk to California’s coastline,” said Patrick Barnard, the lead author of the study. “There are about $12 billion in properties that are at risk of extreme storm today, but if you look out into the future, let’s say mid-century, those numbers roughly triple to about $30 billion of property at risk with just a little bit of sea level rise, and it goes up from there,” USGS researchers Patrick L. Barnard and colleagues write in Scientific Reports.

  • Nuclear weapons might save the world from an asteroid strike – but we need to change the law first

    The schlocky 1998 Bruce Willis movie Armageddon was the highest grossing film of that year. The blockbuster saw a master oil driller (Willis) and an unlikely crew of misfits place a nuclear bomb inside a giant asteroid heading for Earth, blow it up – and save humanity. Armageddon isn’t exactly a documentary: it’s packed full of sci-fi nonsense. But, 20 years on, its basic plot – of using a nuclear explosion to avert a cataclysmic asteroid collision – doesn’t seem quite as silly as it did at the time.
