• Identifying, analyzing drone-collected evidentiary data

    DHS awards nearly $1 million to a Colorado company to develop ways to increase law enforcement capabilities to identify, collect, and analyze evidentiary data from consumer and professional drones. The award is part of S&T’s Cyber Forensics, a project which focuses on development of new capabilities to help law enforcement with the forensic investigations of digital evidence from various devices such as mobile phones and automobile infotainment systems.

  • Magnets manufactured entirely from U.S.-sourced rare earths

    Rare-earth magnets are used in a wide and ever-increasing number of modern technologies, and the ability to produce them domestically could have broad positive impact on national economy and security. The Critical Materials Institute, a U.S. Department of Energy Innovation Hub, has fabricated magnets made entirely of domestically sourced and refined rare-earth metals.

  • New class of chemical vapor sensors

    An interdisciplinary team of scientists demonstrated that monolayer 2D Transition Metal Dichalcogenides (TMDs) — atomically thin semiconductors — undergo a change from semiconductor-to-metallic phase when exposed to airborne chemical vapors. The team validated optical and electronic evidence of the phase transition and how the behavior can be used to create an entirely new class of chemical vapor sensors. This new class of instruments are potentially more sensitive than current state-of-the-art models, and selective to specific nerve agents and explosive compounds which are of great concern on today’s battlefields.

  • Climate change-driven increase in precipitation bad news for water quality

    If climate change is not curbed, increased precipitation could substantially overload U.S. waterways with excess nitrogen. Rainfall and other precipitation washes nutrients from human activities like agriculture and fossil fuel combustion into rivers and lakes. Excess nutrient pollution increases the likelihood of events that severely impair water quality. The impacts will be especially strong in the Midwest and Northeast.

  • Navy’s railgun ready for operational demos

    The U.S. Navy announced that its electromagnetic railgun is out of the laboratory and ready for field demonstrations. The revolutionary railgun relies on a massive electrical pulse, rather than gunpowder or other chemical propellants, to launch projectiles at distances over 100 nautical miles—and at speeds that exceed Mach 6, or six times the speed of sound. That velocity allows projectiles to rely on kinetic energy for maximum effect, and reduces the amount of high explosives needed on ships.

  • Updating a nearly 100-year-old law could shore up U.S. helium supply

    Helium is essential for MRIs, the fiber optics that deliver images to our TVs, scientific research, and of course, party balloons. In the past decade, helium prices have sky-rocketed due to supply shortages. But if small updates are made to an old law, the United States could boost its domestic helium output and help keep critical medical tests and electronics running.

  • Climate change threatens European electricity production

    The vulnerability of the European electricity sector to changes in water resources is set to worsen by 2030 as a consequence of climate change. Thermoelectric power stations—including coal, gas, and nuclear plants—use significant amounts of fresh water for cooling purposes. A large gas power station can use an Olympic-sized swimming pool of water per minute. If water is not available, or if it is too warm, power stations have to reduce electricity production, or cease production completely.

  • 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.
