• Intrusion Technologies, Louroe Electronics integrate threat detection t technologies

    Most of the casualties in an active shooter attack are killed or injured in the first three minutes. On average, responders arrive and engage the attackers in 4–11 minutes. Intrusion Technologies says that the its AIMS platform, using Louroe’s Digifact-A microphone, detects and activates 360° protective systems in less than four seconds, stopping the would-be assailant before tragedy strikes.

  • RoboBoat competition tests students’ engineering skills

    Last week, teams of students from thirteen schools—representing six countries—tested their engineering skills by developing autonomous boats during the 11th annual International RoboBoat Competition. The Navy says that that ingenuity will be needed as the desire for autonomous systems continues to grow—not only for the naval service, but across the commercial sector as companies like Dominos, Amazon and Uber all want to use autonomous vehicles for deliveries.  

  • Driverless ferries to replace footbridges

    As towns grow, the need arises for more river and canal crossings. But bridges are expensive and hinder the flow of boat traffic. An autonomous and self-propelled passenger ferry that can “see” kayakers and boats, and that shows up right when you need it, could be an ingenious substitute for footbridges. Soon the prototype for the world’s first driverless electric passenger ferry will be ready to launch in Trondheim, Norway.

  • New simulations show potential impact of major quakes by building location, size

    With unprecedented resolution, scientists and engineers are simulating precisely how a large-magnitude earthquake along the Hayward Fault would affect different locations and buildings across the San Francisco Bay Area. Researchers are leveraging powerful supercomputers to portray the impact of high-frequency ground motion on thousands of representative different-sized buildings spread out across the California region.

  • Replacing TNT with less toxic explosive

    Scientists have developed a novel “melt-cast” explosive material that could be a suitable replacement for Trinitrotoluene, more commonly known as TNT. TNT was first prepared in 1863 by German chemist Julius Wilbrand but its full potential as an explosive wasn’t discovered until 1891. TNT has been in use as a munitions explosive since 1902.

  • Nature’s remedies: Using viruses against drug-resistant bacteria

    With microbial resistance to antibiotics growing into a major global health crisis, researchers at University of California San Diego School of Medicine, in collaboration with national research institutions and private industry, are leveraging hard-won expertise to exploit a natural viral enemy of pathogenic bacteria, creating North America’s first Center for Innovative Phage Applications and Therapeutics (IPATH). The plan is to use viruses as new weapon against multidrug-resistant bacteria.

  • Deep-sea sponges may offer key to antibiotic drug resistance

    Infectious diseases remain a major threat to human health causing millions of deaths worldwide, especially in medically less-developed countries and regions. In 2016, there were an estimated 1.2 million tuberculous deaths, 1.03 million HIV/AIDS deaths, and 719,600 malaria deaths. This situation is significantly worsened by the prevalence of multi-drug resistance. Researchers may have a solution to this problem using sea sponges collected from the ocean depths.

  • Enhanced detection of nuclear events thanks to deep learning

    A deep neural network running on an ordinary desktop computer is interpreting highly technical data related to national security as well as — and sometimes better than — today’s best automated methods or even human experts.

  • Drones could be used to detect dangerous “butterfly” landmines

    It is estimated that there are at least 100 million military munitions and explosives of concern devices in the world, of various size, shape and composition. Millions of these are surface plastic landmines with low-pressure triggers, such as the mass-produced Soviet PFM-1 “butterfly” landmine. Drones could be used to detect dangerous “butterfly” landmines in remote regions of post-conflict countries.

  • Studying swarm behaviors can teach us how to help drones fly safely

    Civil engineers observe how flying insects avoid collisions, to help devise safe, self-regulated systems for drones and driverless cars. “Many types of animals swarm or flock or otherwise move in coordinated ways,” says a researcher. “No individual animal knows what every other animal is doing, yet somehow they move cohesively as a group.”

  • Novel transmitter protects wireless data from hackers

    Today, more than eight billion devices are connected around the world, forming an “internet of things” that includes medical devices, wearables, vehicles, and smart household and city technologies. By 2020, experts estimate that number will rise to more than twenty billion devices, all uploading and sharing data online. But those devices are vulnerable to hacker attacks that locate, intercept, and overwrite the data, jamming signals and generally wreaking havoc. A novel device uses ultrafast “frequency hopping” and data encryption to protect signals from being intercepted and jammed.

  • New app tracks locations, vitals, keeping first responders safe

    When first responders are on a mission, being able to quickly and easily track the location of their fellow responders can be challenging, especially in situations where the team is spread out. Many responders are only able to coordinate their locations by radioing each other or the command post and providing a very detailed message on their exact location. This can be time consuming and can change every second if they are in an emergency situation or on a call. The Watchtower mobile application allows users to track and report their location using the GPS already built into a smartphone.

  • Next-generation water harvester delivers fresh water from air

    Last October, researchers headed down to the Arizona desert, plopped their newest prototype water harvester into the backyard of a tract home and started sucking water out of the air without any power other than sunlight. The successful field test of their larger, next-generation harvester proved what the team had predicted earlier in 2017: that the water harvester can extract drinkable water every day/night cycle at very low humidity and at low cost, making it ideal for people living in arid, water-starved areas of the world.

  • New tool to detect deadly chemical weapon agents: Butterflies

    Every spring caterpillars shed their cocoons, emerging as butterflies. This timeless symbol of change is now being applied to enhanced chemical detection for U.S. soldiers. Researchers from the military service academies, funded by the Defense Threat Reduction Agency’s Chemical and Biological Technologies Department, are using butterflies to detect trace amounts of chemical warfare agents with increased precision and speed.

  • Data science improves lie detection

    Someone is fidgeting in a long line at an airport security gate. Is that person simply nervous about the wait? Or is this a passenger who has something sinister to hide? Even highly trained Transportation Security Administration (TSA) airport security officers still have a hard time telling whether someone is lying or telling the truth – despite the billions of dollars and years of study that have been devoted to the subject. Researchers are using data science and an online crowdsourcing framework called ADDR (Automated Dyadic Data Recorder) to further our understanding of deception based on facial and verbal cues.
