• A Backdoor in Mobile Phone Encryption from the 1990s Still Exists

    Researchers have discovered a security gap in modern mobile phones which is very unlikely to have been created by accident. In fact, it should have been removed back in 2013.The researchers say that the properties that render the cipher so insecure can’t have happened by accident.

  • Compact Lifesaving Drone for Beach Rescue Teams

    A student designs compact lifesaving drone for beach rescue teams after witnessing teenage surfer battle dangerous waves. As part of his final year project, the student designed a small, compact drone that flies above hazardous waters to locate individuals in distress and deploys a buoyancy aid that automatically inflates when hitting the water, helping casualties stay afloat while they wait for a rescue team to reach them.

  • “Less Than 1% Probability” that Increase in Earth’s Energy Imbalance Occurred Naturally

    The fundamental energy balance sheet for our planet is straightforward: Sunlight in, reflected and emitted energy out. If the Earth’s oceans and land surfaces send as much energy back up to space as the sun shines down on us, then our planet maintains equilibrium. But for decades the system has been out of balance, resulting in the growing number, intensity, lethality, and damage of extreme weather events. The reason: The increasing emission of greenhouse gases.

  • Investigating Materials for Safe, Secure Nuclear Power

    A longstanding interest in radiation’s effects on metals has drawn Michael Short into new areas such as nuclear security and microreactors.

  • How Summer 2021 Has Changed Our Understanding of Extreme Weather

    A series of record-breaking natural disasters have swept the globe in recent weeks. Many of these events have shocked climate scientists. Some scientists are beginning to worry they might have underestimated how quickly the climate will change. Or have we just misunderstood extreme weather events and how our warming climate will influence them?

  • Honeypot Security Technique Can Also Stop Attacks in Natural Language Processing

    Borrowing a technique commonly used in cybersecurity to defend against these universal trigger-based attacks, researchers at the Penn State College of Information Sciences and Technology have developed a machine learning framework that can proactively defend against the same types of attacks in natural language processing applications 99 percent of the time.

  • Maximum Privacy for Sharing Files Online

    People who share documents or pictures online, or organizations which share confidential documents with employees and others, have little to no control over who views the information which is being sent and where it is being viewed. An FAU researcher has received a patent from the U.S. Patent and Trademark Office for a novel invention that controls how and when shared documents are displayed.

  • Preventing Human-Induced Earthquakes

    When humans pump large volumes of fluid into the ground, they can set off potentially damaging earthquakes, depending on the underlying geology. This has been the case in certain oil- and gas-producing regions. have developed a method to manage such human-induced seismicity, and have demonstrated that the technique successfully reduced the number of earthquakes occurring in an active oil field.

  • Climate Tipping Points Are Now Imminent: Scientists

    Around 13,000 researchers have called for urgent action to slow down the climate emergency as extreme weather patterns shock the world. They listed three core measures.

  • Can Drone Warfare in the Middle East Be Controlled?

    Drone attacks are causing a crisis in the Mideast and experts are calling for a better regulatory regime. The drone attacks are part of a worrisome trend in the region: The escalating use of UAVs, both for surveillance purposes and to attack opponents, by countries in the region — but also by nonstate actors there, like militia groups in Iraq, Yemen and Syria, among others. But would more rules even have an impact in the region?

  • Better Batteries for Grid-Scale Energy Storage

    Molten sodium batteries have been used for many years to store energy from renewable sources, such as solar panels and wind turbines. However, commercially available molten sodium batteries, called sodium-sulfur batteries, typically operate at 520-660 degrees Fahrenheit. Sandia Lab’s new molten sodium-iodide battery, using low- cost materials, operates at a much cooler 230 degrees Fahrenheit instead.

  • A 20-Foot Sea Wall Won’t Save Miami – How Living Structures Can Help Protect the Coast and Keep the Paradise Vibe

    There’s no question that the city is at increasing risk of flooding as sea level rises and storms intensify with climate change. But the sea wall the Army Corps is proposing – protecting only 6 miles of downtown and the financial district from a storm surge – can’t save Miami and Dade County. There are more effective – and cheaper solutions.

  • Extreme Heat Waves in a Warming World Don’t Just Break Records – They Shatter Them

    Scientists have warned for over 50 years about increases in extreme events arising from subtle changes in average climate, but many people have been shocked by the ferocity of recent weather disasters. We need to understand two things about climate change’s role in extreme weather like this: First, humans have pumped so much carbon dioxide and other planet-warming greenhouse gases into the atmosphere that what’s “normal” has shifted. Second, not every extreme weather event is connected to global warming.

  • Cities Unprepared for Intense, Frequent Heat Waves

    Urban centers across the world are unprepared to face brutal, climate change-driven natural disasters. Many emerging global climate risks, such as heat stress, will be especially damaging in urban areas, because of urban infrastructure both exacerbates and fails to handle extreme heat. With over 50 percent of the world’s population residing in densely populated urban areas, heat-related deaths, economic disruption, and infrastructural damage are becoming a growing concern.

  • Protecting Lives on the Wildland Fire Line

    Unlike first responders who fight structural fires, wildland firefighters are unable to use the current standard respirator systems, which are heavy, limited to 45 minutes of air and are too bulky. Since the current standard equipment for respiratory protection is a bandanna, DHS S&T and partners designed the Wildfire Respirator around a lightweight mask covering just the mouth and nose, relying on filtration rather than on heavy tanks of compressed air.
