• 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.

  • 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.

  • A Human-Machine Collaboration to Defend Against Cyberattacks

    By Zach Winn

    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.

  • Mixed-Signal Hardware Security Thwarts Powerful Electromagnetic Attacks

    Security of embedded devices is essential in today’s internet-connected world. Security is typically guaranteed mathematically using a small secret key to encrypt the private messages. When these computationally secure encryption algorithms are implemented on a physical hardware, they leak critical side-channel information in the form of power consumption or electromagnetic radiation. Now, researchers have developed technology to kill the problem at the source itself – tackling physical-layer vulnerabilities with physical-layer solutions.

  • WWI Helmets Protect Against Shock Waves as Well as or Better than Modern Designs

    Biomedical engineers have demonstrated that, despite significant advancements in protection from ballistics and blunt impacts, modern military helmets are no better at protecting the brain from shock waves created by nearby blasts than their First World War counterparts. And one model in particular, the French Adrian helmet, actually performed better than modern designs in protecting from overhead blasts.

  • How to Deflect an Asteroid

    By Jennifer Chu

    MIT researchers have devised a framework for deciding which type of mission would be most successful in deflecting an incoming asteroid. Their decision method takes into account an asteroid’s mass and momentum, its proximity to a gravitational keyhole, and the amount of warning time that scientists have of an impending collision — all of which have degrees of uncertainty, which the researchers also factor in to identify the most successful mission for a given asteroid.

  • Tool Identifies Source of Errors Caused by Software Updates

    We’ve all shared the frustration — software updates that are intended to make our applications run faster inadvertently end up doing just the opposite. These bugs, dubbed in the computer science field as performance regressions, are time-consuming to fix since locating software errors normally requires substantial human intervention. Researchers and computer scientists have designed a tool to identify the source of errors caused by software updates.

  • Aliens May Be Sending Us Probing Messages Every 16 Days

    Is there intelligent life out there in the universe? If so, have these intelligent aliens seen us? Have they been trying to find out more about us? New research says they may have been. A just-published scientific paper presents details of blasts of radio waves sent every 16 days from a nearby massive spiral galaxy. Are these radio waves, aimed in the direction of Earth, generated by aliens? Note that the spiral  galaxy in question is 500 million light years distant: Even if the fast radio bursts (FRBs) detected were generated by an intelligent civilization, that civilization may no longer exist.

  • The Next Deadly Pathogen Could Come from a Rogue Scientist. Here’s How We Can Prevent That.

    In the past few years, something new has become possible in biology: cheaply “printing” DNA for insertion into a cell. Kelsey Piper writes in Vox that this means a scientist who needs a particular DNA sequence to, say, create new bacteria for research can now order that DNA sequence from a lab. “But what if I asked them to print for me the genetic code of the influenza that caused the 1918 flu that killed millions of people? What if I sent them the instructions for a new disease that I have reason to believe is dangerous? What if I was doing legitimate research, but my lab didn’t adhere to modern safety standards?”

  • Forensic Proteomics: Going Beyond DNA Profiling

    A new book details an emerging forensic method that could become as widespread and trustworthy as DNA profiling. The method is called mass-spectrometry-based proteomics, which examines the proteins that make up many parts of living things. These proteins exist in unique combinations in everything from blood cells and clothing fibers to certain types of medicine and the diseases they fight. Because proteomics analyzes these proteins directly, forensic proteomics can fill in when DNA is missing, ambiguous, or was never present to begin with.

  • The Silent Threat of the Coronavirus: America’s Dependence on Chinese Pharmaceuticals

    By Christine Crudo Blackburn, Andrew Natsios, Gerald W Parker, and Leslie Ruyle

    As the new coronavirus, called 2019-nCoV, spreads rapidly around the globe, the international community is scrambling to keep up. In the midst of all of this, a potential crisis simmers in the shadows: The global dependence on China for the production of pharmaceuticals and medical equipment. Today, about 80 percent of pharmaceuticals sold in the U.S. are produced in China. This number, while concerning, hides an even greater problem: China is the largest and sometimes only global supplier for the active ingredient of some vital medications. The U.S. must develop a response plan for the inevitable shortages in the near-term and take necessary actions to reclaim control of our medical supply chain. Continuing to overlook this long-known vulnerability will only lead to catastrophe.
