• June Ends with Exceptional Heat

    As an exceptional and dangerous heatwave is baking the Northwestern U.S. and Western Canada, the World Meteorological Organization (WMO) says that so many records have been broken that it is difficult to keep track.

  • Disaster Response and Mitigation in an AI World

    Accurately forecasting the movement of natural disasters—wildfires, floods, hurricanes, windstorms, tornados, and earthquakes—gives first responders a jump, allowing them to take measures to reduce damage, conduct advanced resource planning, and increase infrastructure restoration time.

  • Using Intelligent Drones for Search and Rescue

    Finding people lost (or hiding) in the forest is difficult because of the tree cover. People in planes and helicopters have difficulty seeing through the canopy to the ground below, where people might be walking or even laying down. The same problem exists for thermal applications—heat sensors cannot pick up readings adequately through the canopy. New drone technology helps search and rescue teams locate missing persons - even in dense forests.

  • For Flood-Prone Cities, Seawalls Raise as Many Questions as They Answer

    The U.S. Army Corps of Engineers, whose mission includes maintaining waterways and reducing disaster risks, has recently proposed building large and expensive seawalls to protect a number of U.S. cities, neighborhoods and shorelines from coastal storms and rising seas. As a scientist who studies the evolution and development of coastlines and the impacts of sea level rise, I believe that large-scale seawalls, which cost billions of dollars to build, are almost certainly a short-term strategy that will protect only a few cities, and will protect only selected portions of those cities effectively.

  • Harvesting Fresh Water from Humidity around the Clock

    Fresh water is scarce in many parts of the world and must be obtained at great expense. Communities near the ocean can desalinate sea water for this purpose, but doing so requires a large amount of energy. Further away from the coast, practically often the only remaining option is to condense atmospheric humidity through cooling. Current technologies allow water harvesting only at night, but a new technology, for the first time, allows water harvesting 24 hours around the clock, even under the blazing sun.

  • Is it a Virus or Bacteria? New Tech Rapidly Tests for Pathogens

    The first line of defense against pandemics is the ability quickly to detect the presence or absence of previously unknown pathogens. DHS S&T is exploring a new technology that can discriminate between bacterial and viral infections using only a single drop of blood per patient.

  • New Irrigation Tool Promotes Efficient Water Use and Environmental Stewardship

    Irrigation technology has developed to the point where pressurized pipes can deliver water for irrigation while generating in-conduit hydropower that can be used to power electric pumps that currently rely on diesel, and in the future, also power electric tractors and combines.

  • A Simple Simulation Helps Coastal Towns Plan for Rising Sea Levels

    Climate change causes sea level rise and increasingly strong coastal storms. Knowing how water moves through coastal structures can yield important insights for residents and planners.

  • Rethinking Research Security

    How can or should the United States protect the gains of innovation without damaging the very research base it wants to protect? Ainikki Riikonen and Emily Weinstein write that the U.S. government has rightfully identified the People’s Republic of China (PRC) as an adversary intent on stealing technology for its national interests, and the Department of Justice established the China Initiative as a countermeasure. “But the China Initiative misses the mark on an effective approach to research security. It is out of alignment with evolving research security initiatives in the rest of the federal government…. In its current form, research security under the China Initiative may damage America’s ability to innovate and continue defining the cutting edge of technological research in the long term.”

  • Making Our Computers More Secure

    Corporations and governments rely on computers and the internet to run everything, but security hacks just this past month —  including the Colonial Pipeline security breach and the JBS Foods ransomware attacks  — demonstrated, yet again, how vulnerable these systems are. Researchers presented new systems to make computers safer.

  • Natural Hazards Threaten 57% of U.S. Structures

    As a result of increasing temperatures and environmental changes, more than half of the structures in the contiguous United States are exposed to potentially devastating natural hazards—such as floods, tornadoes, hurricanes, and wildfires.

  • Developing Drones to Address Pandemic-Related Challenges in Scandinavia

    The onset of the Covid-19 pandemic spurred an immediate need to develop new, innovative systems in supply chains and infrastructure. And for three Norwegian graduate students enrolled in the MIT Professional Education Advanced Study Program (ASP), spring 2020 was the moment when technology, innovation, and preparation met opportunity. The students began working together to transport biological samples using autonomous vehicles.

  • Can China Keep Rising?

    “The East is rising,” Chinese leaders took to declaring around the time U.S. President Joe Biden entered office, “and the West is declining.” Daniel Kurtz-Phelan, the executive editor of Foreign Affairs, writes that while the second part of that declaration may draw eye rolls or angry objections in Washington and allied capitals, “the first has become a point of near consensus: a self-assured China, bolstered by years of dazzling economic performance and the forceful leadership of Xi Jinping, has claimed its place as a world power and accepted that long-term competition with the United States is all but inevitable as a result.” He notes, though, that “past performance does not guarantee future results.”

  • Role of Managed Retreat as a Climate Change Response

    Managed retreat—the climate adaptation response of moving people and property out of harm’s way— is becomig more appealing as one of several responses to sea-level rise. Researchers explore what it would take for managed retreat to be supportive of people and their priorities. The key is to consider retreat alongside other responses like coastal defenses, and not just as an option of last resort.

  • “Managed Retreat” Can Reinvent Cities While Protecting Lives When Climate Change Floods, Burns or Bakes the Land

    Record-breaking heat waves; megadroughts, drying fresh-water sources; hotter and more frequent wildfires; intensifying hurricanes — this is what climate change looks like, and communities need to be prepared. Sometimes small adaptations can help reduce the heat or minimize the damage. But when the risks get too high, one strategy that has to be considered is managed retreat – the purposeful movement of people, buildings and other infrastructure away from highly hazardous places.
