• Troubled flood insurance program traps homeowners in flood-prone areas

    The U.S. flood insurance program has repeatedly rebuilt some of the most flood-prone properties in the country, unintentionally setting a trap for owners of modest homes who would prefer to move out of harm’s way, according to a new national report. Today it is thousands of properties, but climate change and rising sea levels threaten to flood millions of properties in the coming decades. For every $100 the nation spends to rebuild homes with national flood insurance funds, FEMA spends just $1.72 to better protect people by moving them to safer, less flood-prone land.

  • Shifting storms threaten once placid areas with extreme waves, extensive damage

    The world’s most extensive study of the impacts of coastal storm fronts in a changing climate has found that rising seas are no longer the only threat. The study of a major storm front striking the coast has revealed a previously unrecognized danger from climate change: as storm patterns fluctuate, waterfront areas once thought safe are likely to be hammered and damaged as never before.

  • Better technologies help first responders respond more quickly, safely, and effectively

    When disaster strikes, first responders rush in to provide assistance. In addition to their courage and training, they depend on a panoply of technologies to do their jobs. Pacific Northwest National Laboratory has partnered with emergency management and public safety professionals to define, develop, test and deploy these technologies to improve response and recovery. The Lab also applies its scientific capabilities to assess emergencies as they unfold.

  • Three advanced first-response technologies funded

    The Israel-U.S. Binational Industrial Research and Development (BIRD) Foundation awarded funding to three homeland security projects, selected by DHS and MOPS, between U.S. and Israeli companies to advance technologies for first responders. In addition to the grants from BIRD, the projects will access private sector funding, boosting the total value of the three projects to approximately $7 million. The program funds technology collaborations between U.S. and Israeli partners that have significant commercial potential to meet the most pressing requirements of first responders.

  • A “cocktail” of geoengineering approaches to combat climate change

    Geoengineering is a catch-all term that refers to various theoretical ideas for altering Earth’s energy balance to combat climate change. New research from an international team of atmospheric scientists investigates for the first time the possibility of using a “cocktail” of geoengineering tools to reduce changes in both temperature and precipitation caused by atmospheric greenhouse gases.

  • Making gene editing safer

    Gene editing technologies have captured increasing attention from healthcare professionals, policymakers, and community leaders in recent years for their potential to cure disease, control mosquito populations, and much more. The potential national security applications and implications of these technologies are equally profound, including protection of troops against infectious disease, mitigation of threats posed by irresponsible or nefarious use of biological technologies, and enhanced development of new resources derived from synthetic biology, such as novel chemicals, materials, and coatings with useful, unique properties. DARPA is funding the efforts of seven teams aiming to develop new knowledge and tools to support responsible innovation in gene editing and protect against threats to genome integrity.

  • Soft, growing robot for searching people under collapsed buildings

    Imagine rescuers searching for people in the rubble of a collapsed building. Instead of digging through the debris by hand or having dogs sniff for signs of life, they bring out a small, air-tight cylinder. They place the device at the entrance of the debris and flip a switch. From one end of the cylinder, a tendril extends into the mass of stones and dirt, like a fast-climbing vine. A camera at the tip of the tendril gives rescuers a view of the otherwise unreachable places beneath the rubble. This is just one possible application of a new type of robot – a robot that can grow across long distances without moving its whole body.

  • NSA funds cybersecurity project to bolster security of cloud-based computing

    A University of Arkansas at Little Rock researcher has received funding from the U.S. National Security Agency (NSA) to improve cybersecurity skills for students and the general population. The cybersecurity lab project, “Networking and Network Security in the Cloud (NetSiC),” will address issues related to cloud-based computing environments and help students practice networking and cyber defense skills.

  • 20-story earthquake-safe buildings made from wood

    Engineering researchers are putting a two-story wooden structure through a series of powerful earthquake simulations, using a lab shake table. The goal is to gather the data required to design wood buildings as tall as twenty stories that do not suffer significant damage during large earthquakes.

  • Building to better weather the storm

    The Atlantic hurricane season has officially begun and the National Oceanic and Atmospheric Administration (NOAA) is predicting “above normal” storm activity this year. That could mean significant damage to coastal communities — some of which are still recovering from last year’s hurricane season. New dashboard developed by the MIT Concrete Sustainability Hub helps builders calculate the breakeven cost of hazard mitigation in hurricane-prone areas.

  • Dust Bowl redux: Increase in dust storms in the U.S.

    Could the storms that once engulfed the Great Plains in clouds of black dust in the 1930s once again wreak havoc in the United States? A new statistical model developed by researchers predicts that climate change will amplify dust activity in parts of the United States in the latter half of the 21st century, which may lead to the increased frequency of spectacular dust storms that have far-reaching impacts on public health and infrastructure.

  • Young engineers pedal their way to underwater dominance

    What do a shark, coffin and ice cream cone have in common? They’re all student-built, human-powered submarines—and they competed in the 14th biennial International Submarine Races (ISR), recently held at the Naval Surface Warfare Center (NSWC) Carderock Division, in Bethesda, Maryland. ISR is a biennial event where participants design, build and race one- or two-person, human-powered submarines down a 328-feet underwater course in the David Taylor Model Basin.

  • Automated security kiosk to shorten lines at airports, border crossings

    Researchers have developed a next-generation automated screening kiosk which uses an algorithm of “yes” or “no” questions delivered by a computer-generated avatar, quickly and efficiently to assess the potential threats passengers may pose to others. the screening can be completed in less than four minutes with a 90 percent success rate.

  • What an artificial intelligence researcher fears about AI

    As an artificial intelligence researcher, I often come across the idea that many people are afraid of what AI might bring. It’s perhaps unsurprising, given both history and the entertainment industry, that we might be afraid of a cybernetic takeover that forces us to live locked away, “Matrix”-like, as some sort of human battery. Might I become “the destroyer of worlds,” as Robert Oppenheimer lamented after spearheading the construction of the first nuclear bomb? Perhaps the critics are right. Maybe I shouldn’t avoid asking: As an AI expert, what do I fear about artificial intelligence?

  • Rising temperatures may limit aircraft takeoffs globally

    Global temperatures have gone up nearly 1 degree Centigrade (1.8 Fahrenheit) since about 1980, and this may already be having an effect. In late June, American Airlines canceled more than 40 flights out of Phoenix, Ariz., when daytime highs of nearly 120 degrees made it too hot for smaller regional jets to take off. Rising temperatures due to global warming will make it harder for many aircraft around the world to take off in coming decades, says a new study. During the hottest parts of the day, 10 to 30 percent of fully loaded planes may have to remove some fuel, cargo or passengers, or else wait for cooler hours to fly, a new study shows.
