• Radar Can Help Fight Wildfires, Identify Flash-Flood Risks

    Radar imaging technology can provide valuable insight into the location and extent of wildfires in remote Arctic and Subarctic forests, like those currently burning in Canada. Capable of penetrating clouds and smoke, and imaging day and night, Interferometric Synthetic Aperture Radar (InSAR) can play a critical role in wildfire monitoring.

  • Next-Generation Flow Battery Design Sets Records

    Sugar additive plays a surprising role, boosting flow battery capacity and longevity for this grid energy resilience design. Researchers report that the flow battery, a design optimized for electrical grid energy storage, maintained its capacity to store and release energy for more than a year of continuous charge and discharge.

  • Forensics Lab Cracks Case on Newer, “Greener” Gunshot Residue

    Discoveries by forensic scientists about how gunshot residue behaves on skin, hair and fabric will allow crime scene investigators to catch up to the proliferation of new, eco-friendly types of ammunition and make faster, more informed decisions at crime scenes and in forensic laboratories.

  • What Are the Odds of a Truly Catastrophic, Even Extinction-Causing, Disaster?

    The Forecastong Research Institute (FRI) brought together forecasters from two groups with distinctive claims to knowledge about humanity’s future — experts in various domains relevant to existential risk, and “superforecasters” with a track record of predictive accuracy over short time horizons. FRI asked tournament participants to predict the likelihood of global risks related to nuclear weapon use, biorisks, and AI, along with dozens of other related, shorter-run forecasts.

  • A Quantitative Analysis of the In-Orbit Collision Risk and Its Effects on the Earth

    Since the launch of the first satellite in 1957, the proliferation of space debris has continued unabated. The European Space Agency (ESA) estimates that over 131 million useless objects, ranging from 1 millimeter to 10 centimeters in size, currently orbit the Earth at an average speed of 36,000 kilometers per hour. “Any fragment larger than 1 centimeter poses a potentially lethal threat in the event of a collision,” says an expert.

  • Sooner Than You Might Think: Virtual Power Plants Are Coming to Save the Grid

    Networks of thousands of home-based batteries could be key to a cleaner, more reliable electricity system. After years of pilot projects, utilities and battery companies now have networks with thousands of participants in California, Utah, and Vermont, among others.

  • Researchers Devise a Way to Evaluate Cybersecurity Methods

    A savvy hacker can obtain secret information, such as a password, by observing a computer program’s behavior, like how much time that program spends accessing the computer’s memory. Security approaches that completely block these “side-channel attacks” are so computationally expensive, so engineers often apply what are known as obfuscation schemes. MIT researchers have developed a system which analyzes the likelihood that an attacker could thwart a certain security scheme to steal secret information.

  • How Secure Are Voice Authentication Systems Really?

    Voice authentication has increasingly been used in remote banking, call centers and other security-critical scenarios. Attackers can break voice authentication with up to 99 percent success within six tries.

  • Energy Transition with Hydrogen Generated on Rooftops

    Efficient production of hydrogen, fuels, and even drinking water on roofs or in solar parks – this is what researchers want to achieve with low-cost photoreactor modules. Now, they have made major progress.

  • U.S. Agencies Buy Vast Quantities of Personal Information on the Open Market – a Legal Scholar Explains Why and What It Means for Privacy in the Age of AI

    The issues pf the protection of personal information in the digital age is increasingly urgent. Today’s commercially available information, coupled with the now-ubiquitous decision-making artificial intelligence and generative AI like ChatGPT, significantly increases the threat to privacy and civil liberties by giving the government access to sensitive personal information beyond even what it could collect through court-authorized surveillance.

  • Testing Next Generation Flood and Wildfire Alerting Technology

    DHS S&T conducted a demonstration of new technology that integrates unattended flood and wildfire sensors with Integrated Public Alert Warning System (IPAWS) with Open Platform for Emergency Networks (IPAWS-OPEN). These systems have the potential to provide life-saving critical emergency alerts to people in affected areas.

  • Tidal Energy Project for Carbon Emission Reduction and Energy Security

    The University of Oxford will lead an ambitious £7 million project to help deliver scalable, affordable and sustainable tidal stream energy. The project will address the key challenges that are currently preventing the tidal energy sector from reaching its full potential, with the aim of boosting energy security.

  • FireDrone Supports the Firefighters

    Researchers are developing a heat-resistant drone that can analyze the source of danger at close range in the event of a building or forest fire. This allows firefighters to optimize the strategy of a high-risk operation before entering the danger zone.

  • Four Ways Criminals Could Use AI to Target More Victims

    Warnings about artificial intelligence (AI) are ubiquitous right now, but we have been using AI tools for a long time. AI is a tool to increase efficiency, process and sort large volumes of data, and offload decision making – and these tools are open to everyone, including criminals. Observing how criminals have adapted to, and adopted, technological advances in the past, can provide some clues as to how they might use AI.

  • Titan Destroyed by “Catastrophic Implosion”

    The U.S. Coast Guard announced Thursday afternoon that the Titan submersible was likely destroyed by a catastrophic implosion. The Titan joins a sad, and long, list of lethal maritime accidents.
