• Flood Bot: New Flood Warning Sensors

    Ellicott City, Maryland, suffered devastating floods in 2016 and 2018. The disasters left residents and officials wondering how technology could help predict future severe weather, and save lives and property. Scientists offer an answer: The Flood Bot network.

  • New Nontoxic Ammunition

    Every time a gun fires, lead leaches into the air. A scientific advancement could provide a comparable replacement for lead-based explosive materials found in ammunition, protecting soldiers and the environment from potential toxic effects.

  • During Droughts: Where Is the Water?

    In low precipitation periods – where and how is the limited available water distributed and what possibilities are there for improving retention in the soil and the landscape?

  • Using Frequency Analysis to Recognize Fake Images

    They look deceptively real, but they are made by computers: so-called deep-fake images are generated by machine learning algorithms, and humans are pretty much unable to distinguish them from real photos. New method makes it possible to expose fake images created by computer algorithms rather than by humans.

  • Touting Criticized Study, White House Presses FDA to Authorize Hydroxychloroquine — Again

    In March, the FDA, on scant evidence, initially gave emergency use authorization to hydroxychloroquine. The agency in April issued a safety warning about potential cardiac problems before withdrawing its approval last month. The reason for the FDA authorization withdrawal was the results of several large-scale, randomized, double-blind trials, all of which showed that not only does hydroxychloroquine offer no benefits to COVID-19-infetced patients, but that it substantially increases the risk of serious heart problems and heart-related deaths. Laurie McGinley and Josh Dawsey write in the Washington Post that earlier this month, a Henry Ford Health System study found death rates were 50 percent lower among the patients treated with hydroxychloroquine, the authors said. They also said the drug posed no safety problems. The study has been criticized by scientists, but the White House and Trump supporters in the media have urged the FDA to reauthorize hydroxychloroquine for emergency use.

  • Venice Ambitious Anti-Flood System Passes First Trial

    Venice On Friday conducted the first test of a controversial dam system made up of 78 inflatable barriers, aiming to protect the city from severe flooding. The ambitious and costly dam system, launched in 2003, has been plagued by corruption and is nearly a decade behind schedule. It will becoe fully operational by the end of 20201, and it is designed to hold water surges as high as 10 feet.

  • Securing the Smart Home

    So…you’ve built your smart home, it’s got smart heating and lighting, all the latest smart communications and entertainment systems, and of course, smart power generation to make it smart and green. But, how do you keep it secure and stop forced digital or physical entry? Well, you need smart security too, of course.

  • Roadmap for Studying Link between Climate and Armed Conflict

    Climate change—from rising temperatures and more severe heavy rain, to drought—is increasing risks for economies, human security, and conflict globally. Scientists are offering ways better to assess the climate-conflict link to help societies manage the complex risks of increased violence from a changing climate.

  • Quiet and Green: Why Hydrogen Planes Could Be the Future of Aviation

    Today, aviation is responsible for 3.6 percent of EU greenhouse gas emissions. Modern planes use kerosene as fuel, releasing harmful carbon dioxide into the atmosphere. But what if there was another way? One possible solution is to use a new type of fuel in planes that doesn’t produce harmful emissions – hydrogen. Long touted as a sustainable fuel, hydrogen is now gaining serious traction as a possibility for aviation, and already tests are under way to prove its effectiveness.

  • Accurately Pinpointing Malicious Drone Operators

    Researchers have determined how to pinpoint the location of a drone operator who may be operating maliciously or harmfully near airports or protected airspace by analyzing the flight path of the drone.

  • Privacy Risks of Home Security Cameras

    Researchers have used data from a major home Internet Protocol (IP) security camera provider to evaluate potential privacy risks for users. The researchers found that the traffic generated by the cameras could be monitored by attackers and used to predict when a house is occupied or not.

  • Improving Ethical Models for Autonomous Vehicles

    There’s a fairly large flaw in the way that programmers are currently addressing ethical concerns related to artificial intelligence (AI) and autonomous vehicles (AVs). Namely, existing approaches don’t account for the fact that people might try to use the AVs to do something bad.

  • Future Texas Hurricanes: Fast Like Ike or Slow Like Harvey?

    Climate change will intensify winds that steer hurricanes north over Texas, increasing the odds for fast-moving storms like 2008’s Ike compared with slow-movers like 2017’s Harvey, according to new research.

  • Increases in Greenhouse Gas, Particulate Pollution Emissions Drive Drying around the Globe

    Researchers have identified two signatures or “fingerprints” that explain why arid conditions are spreading worldwide, and why the Western United States has tended toward drought conditions since the 1980s while the African Sahel has recovered from its prolonged drought.

  • Heatwave Trends Accelerate Worldwide

    The first comprehensive worldwide assessment of heatwaves down to regional levels has revealed that in nearly every part of the world heatwaves have been increasing in frequency and duration since the 1950s. New research has also produced a new metric, cumulative heat, which reveals exactly how much heat is packed into individual heatwaves and heatwave seasons. As expected, that number is also on the rise.
