• How Easy Is it to Build a Robot Assassin?

    Someone—almost certainly Israel—recently assassinated Mohsen Fakhrizadeh, the leading scientist behind the Iranian nuclear program. The latest reporting from Iran suggests that the assassins employed a remotely controlled machine gun mounted on a pickup truck. So how hard is it to build such a tool? How expensive? Nicholas Weaver writes that “Unfortunately, the answer is “hard but doable” and “not much money”—with the further complication that in a few years, it will probably be possible to pick up the necessary equipment online from vendors like Banggood.”

  • Novel Chemical Process a First Step to Making Nuclear Fuel with Fire

    Uranium dioxide, a radioactive actinide oxide, is the most widely used nuclear fuel in today’s nuclear power plants. A new “combustion synthesis” process recently established for lanthanide metals—non-radioactive and positioned one row above actinides on the periodic table—could be a guide for the production of safe, sustainable nuclear fuels.

  • Guidance Will Improve Critical Infrastructure Resilience

    It is easy to understand the importance of our “critical infrastructure,” such as telecommunications, energy, transportation, and emergency services, but what’s often overlooked are the underlying technologies that enable them. DHS S&T is doing something about it.

  • Study Identifies Reasons for Soaring Nuclear Plant Cost Overruns in the U.S.

    Analysis points to ways engineering strategies could be reimagined to minimize delays and other unanticipated expenses. Many analysts believe nuclear power will play an essential part in reducing global emissions of greenhouse gases, and finding ways to curb these rising costs could be an important step toward encouraging the construction of new plants.

  • Putting Nuclear Reactors in Space

    A new agreement hopes to speed along a nuclear reactor technology that could be used to fuel deep-space exploration and possibly power human habitats on the Moon or Mars.

  • Your Smart Watch May Be Sharing Your Data

    You may not realize it, but your internet-connected household devices such as the Ring doorbell, Peloton exercise bike and Nest thermostat are all exchanging data with other devices and systems over the network. These physical objects, all part of the Internet of Things (IoT), come with sensors and software, and they often use cloud computing. Most people would consider the information contained in these household items as highly private.

  • System Brings Deep Learning to “Internet of Things” Devices

    Deep learning is everywhere. This branch of artificial intelligence curates your social media and serves your Google search results. Soon, deep learning could also check your vitals or set your thermostat. Advanced could enable artificial intelligence on household appliances while enhancing data security and energy efficiency.

  • Putting Games to Work in the Battle Against COVID-19

    While video games often give us a way to explore other worlds, they can also help us learn more about our own — including how to navigate a pandemic. That was the premise underlying “Jamming the Curve,” a competition that enlisted over 400 independent video game developers around the world to develop concepts for games that reflect the real-world dynamics of COVID-19.

  • New Body Armor Offers Better Knife Protection

    The number of knife attacks in Britain has increased over the past few years, while police officers and correctional personnel must contend with an increasing threat from makeshift weapons, such as shanks and spikes. PPSS Group the other day announced a replacement for their polycarbonate-based stab resistant body armor. According to company CEO Robert Kaiser, the new body armor is lighter, thinner, more effective, and more functional.

  • Cloud-Based Framework Improves Efficiency in Disaster-Area Management

    Researchers have, for the first time, designed a cloud-based autonomous system framework utilizing the standard messaging protocol for the internet-of-things (IoT). This framework is robust to network-denied environments by utilizing each vehicle, along with a clustering algorithm, to maximize the network coverage area. Also for the first time, researchers have implemented a cloud-based, highly efficient control system to aid first responders in disaster-area management.

  • World's Fastest Open-Source Intrusion Detection Is Here

    Intrusion detection systems are the invisible intelligence agencies in computer networks. They scan every packet of data that is passed through the network, looking for signs of any one of the tens of thousands of different types of cyberattacks they’re aware of. A newly developed intrusion detection system achieves speeds of 100 gigabits per second using a single server.

  • Policy, Not Tech, Spurred Danish Dominance in Wind Energy

    In emerging renewable energy industries, are producers’ decisions to shut down or upgrade aging equipment influenced more by technology improvements or government policies? It’s an important long-term question for policymakers seeking to increase renewable electricity production, cost-effectiveness and efficiency with limited budgets. Anew study focused on Denmark, a global leader in wind energy found that government policies have been the primary driver of that industry’s growth and development.

  • FBI: Boogaloo Extremists Acquired 3D-Printed Machine Gun Parts

    Depending on their configuration, 3D-printed guns contain no metal parts, and thus can be smuggled into metal detectors-protected venues. In a criminal complaint filed against a West Virginia men selling 3D-printed gun components, the FBI says his customers included multiple members of the Boogaloo movement, a heavily armed extremist anti-government group.

  • A New World of Warcraft

    In the past decade, high tech tools have proliferated in the world’s fighting forces. At least 80 nations can now deploy remote-controlled drones. Will the widespread use of digitally enhanced arsenals prove a destabilizing, if not destructive, element in the complex struggles among states? Not necessarily, argues MIT assistant professor Erik Lin-Greenberg.

  • Tricking Fake News Detectors with Malicious User Comments

    Fake news detectors, which have been deployed by social media platforms like Twitter and Facebook to add warnings to misleading posts, have traditionally flagged online articles as false based on the story’s headline or content. However, recent approaches have considered other signals, such as network features and user engagements, in addition to the story’s content to boost their accuracies.
