• Laser Defense System against Next Gen Autonomous Attack Drones

    attack drones are becoming increasingly common threats, and future attack drones will be completely autonomous, navigating via onboard sensors and cameras and eschewing any sort of exploitable communication link. In order to neutralize them before they reach their target, a “hard kill” option is needed to physically target and shoot down the drone. A Ben Gurion University (BGU) laser expert has developed a laser-based defense system, dubbed Light Blade (Lahav-Or in Hebrew), that will be able to down the next generation of attack drones.

  • New Flooding Prediction Tool

    By incorporating the architecture of city drainage systems and readings from flood gauges into a comprehensive statistical framework, researchers can now accurately predict the evolution of floods in extreme situations like hurricanes. With their new approach, the researchers said their algorithm could forecast the flow of floodwater in almost real-time, which can then lead to more timely emergency response and planning.

  • Building a Flood Resilient Future

    Seven of the United Kingdom’s ten wettest years on record have occurred since 1998. Its wettest winter in history came in 2013, and the next wettest in 2015. In a single week in November 2019, 400 homes were flooded and 1,200 properties evacuated in northern England. The frequency and severity of these events is expected to increase as a result of climate change, meaning that many more communities will suffer their devastating effects. A new book shows how we can adapt the built and natural environment to be more flood resilient in the face of climate change.

  • Extreme Weather Events Could Bring Next Recession

    Physical climate risk from extreme weather events remains unaccounted for in financial markets. Without better knowledge of the risk, the average energy investor can only hope that the next extreme event won’t trigger a sudden correction, according to new research. Experts say that the market needs to plan for weather risk, or face extreme correction.

  • For Better Cybersecurity, New Tool Fools Hackers into Sharing Keys

    Instead of blocking hackers, a new cybersecurity defense approach actually welcomes them. The method, called DEEP-Dig (DEcEPtion DIGging), ushers intruders into a decoy site so the computer can learn from hackers’ tactics. The information is then used to train the computer to recognize and stop future attacks.

  • A Dam Across the North Sea to Protect Europeans from Sea-Level Rise

    Engineers say that a 475-km-long dam between the north of Scotland and the west of Norway. and another one of 160 km between the west point of France and the southwest of England, could protect more than 25 million Europeans against the consequences of an expected sea level rise.

  • Protecting Sensitive Metadata So It Cannot Be Used for Surveillance

    MIT researchers have designed a scalable system that secures the metadata of millions of users in communications networks, to help protect the information against possible state-level surveillance. The system ensures hackers eavesdropping on large networks cannot find out who is communicating and when they’re doing so.

  • U.S. Mine Produced $86.3 Billion in Minerals in 2019

    U.S. mines produced approximately $86.3 billion in minerals in 2019 –- more than $2 billion higher than revised 2018 production totals. The U.S. continues to rely on foreign sources for some raw and processed mineral materials. In 2019, imports made up more than one-half of U.S apparent consumption for 46 nonfuel mineral commodities, and the U.S. was 100 percent net import reliant for 17 of those. The domestic production of critical rare-earth mineral concentrates increased by 8,000 metric tons (over 44 percent) in 2019 to 26,000 metric tons, making the U.S. the largest producer of rare-earth mineral concentrates outside of China.

  • New Technologies, Strategies Expanding Search for Extraterrestrial Life

    Emerging technologies and new strategies are opening a revitalized era in the search for extraterrestrial intelligence (SETI). New discovery capabilities, along with the rapidly expanding number of known planets orbiting stars other than the Sun, are spurring innovative approaches by both government and private organizations.

  • New Center to Lead Counterterrorism, Terrorism Prevention Research

    DHS S&T has awarded the University of Nebraska at Omaha a 10-year, $36 million grant to establish a DHS Center of Excellence (COE) for Terrorism Prevention and Counterterrorism Research (TPCR). TPCR will lead a consortium of academic, industry, government, and laboratory partners aiming to gain better understanding of terrorism and its sources, and help fashion effective counterterrorism policies.

  • Identifying the Greatest Risk to U.S. Mineral Resource Supplies

    Policymakers and the U.S. manufacturing sector now have a powerful tool to help them identify which mineral commodities they rely on that are most at risk to supply disruptions. The risk tool identified 23 mineral commodities whose supply poses the greatest risk, including those used in consumer electronics, renewable energy, aerospace, and defense applications.

  • Climate Change Poses “High-to-Catastrophic” Security Threats to U.S. Security: Experts

    A comprehensive report finds that plausible climate change trajectories pose “High-to-Catastrophic” threats to U.S. national security. An expert panel analyzed the globe through the lens of the U.S. Geographic Combatant Commands, and concluded that “Even at scenarios of low warming, each region of the world will face severe risks to national and global security in the next three decades. Higher levels of warming will pose catastrophic, and likely irreversible, global security risks over the course of the twenty-first century.”

  • A Human-Machine Collaboration to Defend Against Cyberattacks

    Being a cybersecurity analyst at a large company today is a bit like looking for a needle in a haystack — if that haystack were hurtling toward you at fiber optic speed. PatternEx merges human and machine expertise to spot and respond to hacks.

  • Custom Circuits to Make IoT Systems 14,000 Times Harder to Crack than Current Tech

    The “internet of things” (IoT) allows devices — kitchen appliances, security systems, wearable technologies and many other applications — to communicate with each other through networks. With the world on the verge of adopting them by the billions, the best possible security is paramount. Engineers have one-upped their own technique to increase security for the “internet of things.” In truth, their upping is far greater than one.

  • Emulating Snakes for Building Better Robots for Search-and-Rescue Missions

    Snakes live in diverse environments ranging from unbearably hot deserts to lush tropical forests. But regardless of their habitat, they are able to slither up trees, rocks, and shrubbery with ease. Mechanical engineers design a snake robot based on the climbing technique of the kingsnake. The new design could help advance search-and-rescue technology.
