• Are Buyouts a Viable Tool for Climate Adaptation?

    Sea level rise, and the resulting storm surges and floods, have made managed coastal retreat – the purposeful movement of people, buildings, and other infrastructure away from the coast – an option which more and more communities are considering. The need for adaptive solutions to the growing coastal challenges is clear, but questions remain as to where buyouts by the government of vacated property can and should fit in.

  • Face Off for Best ID Checkers

    A face matching test has been updated to find super-recognizers who can help prevent errors caused by face recognition software. The type of professional roles that involve face identification and that could benefit from the test include visa processors, passport issuers, border control officers, police, contract tracers, as well as security staff in private industry.

  • Recent Technology Cost Forecasts Underestimate Pace of Technological Change

    A comparison of observed global energy technology costs, with forecasts generated by models and forecasts predicted by human experts, showed that both forecasting methods underestimated cost reductions. This suggests that decisions based on forecasts may be overestimating the cost of climate mitigation and points to the need to further improve forecasting methods.

  • Why “Nuclear Batteries” Offer a New Approach to Carbon-Free Energy

    Much as large, expensive, and centralized computers gave way to the widely distributed PCs of today, a new generation of relatively tiny and inexpensive factory-built reactors, designed for autonomous plug-and-play operation similar to plugging in an oversized battery, is on the horizon. These microreactors, trucked to usage sites, could be a safe, efficient option for decarbonizing electricity systems.

  • More Than 100 Deaths Tied to Heat Wave in Pacific Northwest

    More than 100 deaths in Oregon, Washington, and y British Columbia may have been caused by hyperthermia, authorities say, as the region continues to experience record-shattering high temperatures.

  • With Cyberattacks Growing More Frequent and Disruptive, a Unified Approach Is Essential

    Coordinated cyberattacks can create massive disruptions to infrastructure and supply chains. New treaties are needed to prevent cyberwarfare, but it’s challenging to predict technological advances.

  • Building a Better “Canary Trap”

    A new artificial intelligence system generates fake documents to fool adversaries. The system automatically creates false documents to protect intellectual property such as drug design and military technology.

  • Better Method to Predict Offshore Wind Power

    Offshore wind is maturing into a major source of renewable energy, and is projected to grow 15-fold by 2040 to become a $1 trillion industry. Researchers have developed a machine learning model using a physics-based simulator and real-world meteorological data to better predict offshore wind power.

  • An Expert on Search and Rescue Robots Explains the Technologies Used in Disasters Like the Florida Condo Collapse

    Different types of robots may be used to search and rescue victims of disasters, such as the condo collapse in Surfside, Florida. A robotics experts says that the current state of the practice for searching the interior of rubble is to use either a small tracked vehicle, such as an Inkutun VGTV Extreme, which is the most commonly used robot for such situations, or a snakelike robot, such as the Active Scope Camera developed in Japan. Teledyne FLIR is sending a couple of tracked robots and operators to the site in Surfside, Florida.

  • Matt Hancock and the Problem with China’s Surveillance Tech

    Matt Hancock, Britain’s Health Secretary, resigned last week – and informed his wife that he was divorcing her – after CCTV footage emerged of him snogging his assistant outside his office. Ian Williams writes that the Hancock affair raises serious questions involving surveillance and national security: The cameras involved were made by the Chinese company Hikvision, one of the 1.3 million Hikvision cameras installed across the U.K. Hikvision has close links to the Chinese Communist Party and China’s intelligence services. Even if the Chinese intelligence services were not involved in leaking the compromising Hancock video to the press, the episode is one more indication, if one were needed, of the security risks involved in allowing an unregulated access by Chinese technology companies access unfettered and unregulated access to Western markets.

  • Physics-Based Instruction Leads to Success for Geothermal Drilling

    Using the earth’s subsurface heat to change water to steam and power generators to produce electricity is not a new idea. The first large-scale geothermal electricity-generating plant opened in the U.S. in 1960 and has grown to become the most significant energy complex of its kind in the world. But while advances in technology have improved energy production efficiency, one aspect of tapping this renewable resource is still highly cost-prohibitive to those wanting to invest in it: Drilling into the earth.

  • UFOs and Aliens in Germany

    The U.S. government’s release of a report on unidentified aerial sightings has been met with much interest in Germany. Enthusiasts believe UFOs have been sighted here, too. “We’re just a small blue planet in the middle of an infinite universe,” UFO researcher Robert Fleischer says. “Anything is possible out there.”

  • Florida Condo Collapse – Searching for Answers about What Went Wrong in Surfside Can Improve Building Regulation

    How does a building stand for 40 years and then collapse, perhaps with little or no warning? Why did it collapse so that part of the building stayed up, sparing many lives? It might take months or longer for engineers to find answers to these questions. But those reports, when they do come, are important because engineers can use them to improve building codes and other safety measures – and hopefully prevent future collapses.

  • Using Radio Signals to Image Hidden and Speeding Objects

    Radio signals can create real-time images and videos of hidden and moving objects, helping firefighters find escape routes or victims inside buildings filled with fire and smoke. The technique could also be used to track hypersonic objects such as missiles and space debris.

  • Colorado River’s Low-Flow Sheds Light on Eventual New Normal for Grand Canyon

    The Colorado River follows a 1,450-mile route generally southwest from north central Colorado to just east of Las Vegas. From there it turns south to form Arizona’s western border with Nevada and California, and then the border between Mexican states Sonora and Baja California before emptying into the Gulf of California. Between the U.S. and Mexico, 40 million people depend on water from the Colorado.As the climate continues to warm and the amount of water available for humans continues to drop, low flows may become the new normal, he added.
