• We Climate Scientists Won’t Know Exactly How the Crisis Will Unfold Until it’s Too Late

    By Wolfgang Knorr and Will Steffen

    When we hold on to things for too long, change can come about abruptly and even catastrophically. While this will ring true for many from personal experience, similar things can happen at large scales as well. Indeed, the history of Earth’s climate and ecosystems is punctuated by frequent large-scale disruptive events.

  • Novel Cybersecurity Approach to Protect Army Systems

    Networked devices and infrastructure are becoming increasingly complex, making it nearly impossible to verify an entire system, and new attacks are continuously being developed. Researchers have identified an approach to network security that will enhance the effectiveness and timeliness of protection against adversarial intrusion and evasion strategies.

  • Water Cannon Technology Disarms IEDs

    Improvised explosive devices (IEDs) are a constant and ever-changing threat to the security of our nation. Their extreme destructive potential demands innovative solutions. That’s where the Reverse Velocity Jet Tamper (ReVJeT) comes in. ReVJeT breaks apart IEDs by targeting a stream of high-velocity liquid, such as water. It does not detonate the device, but rather disarms it from a distance and allows bomb technicians do their jobs faster, safer, and more effectively.

  • Identify, Track, Capture: Addressing UAS Threats

    Sandia National Laboratories robotics experts are working on a way to intercept enemy unmanned aircraft systems midflight. They successfully tested their concept indoors with a swarm of four unmanned aircraft systems that flew in unison, each carrying one corner of a net. Acting as a team, they intercepted the flying target, trapped it in air like an insect caught in a web and safely lowered it to the ground.

  • Mind Reading: New Software Agents Will Infer What Users Are Thinking

    Personal assistants today can figure out what you are saying, but what if they could infer what you were thinking based on your actions? A team of academic and industrial researchers is working to build artificially intelligent agents with this social skill.

  • A First: New Bridge Building Technology Successfully Used in Austrian Alps

    There are many different methods for erecting bridges, but the new technique — the balanced lowering method — is quite spectacular: the bridge is not built horizontally, as would normally be case, but erected in a vertical position and then rotated into the horizontal position. The new bridge construction technology has now been successfully used in the construction of the Fürstenfeld Motorway in the Austrian Alps.

  • More Accurate Climate Change Model Reveals Bleaker Outlook on Electricity, Water Use

    By 2030, global warming alone could push Chicago to generate 12 percent more electricity per person each month of the summer. If the city generated any less electricity, it would be risking a power shortage that may require drastic measures to avoid rolling blackouts, according to projections from a model designed by Purdue University researchers.

  • 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

    By Tom Almeroth-Williams

    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

    By Rob Matheson

    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.
