• New Computing Security Architecture Protects Sensitive Private Data

    Protecting sensitive information on the internet has become an essential feature for computing architectures. Applications that process such data must trust the system software they rely on, such as operating systems and hypervisors, but such system software is complex and often has vulnerabilities that can risk data confidentiality and integrity.

  • Safer Web Surfing with a New Method for Detecting Malicious Code Patterns

    With the ever-increasing importance of the Internet in our lives, there are growing attempts to exploit software vulnerabilities in our PCs for personal benefit. One way to do so is by infecting the victim’s PC with a malicious code injected through a website. A fast and reliable detection approach can analyze distribution patterns of malicious codes in websites.

  • Pegasus Spyware Maker NSO Is Conducting a Lobbying Campaign to Get Off U.S. Blacklist

    The cybersecurity firm has invested heavily in top lobbyists and law firms in an effort to lift restrictions on doing business in America. NSO is hoping the Israeli prime minister will raise the issue with Joe Biden when the two meet this week.

  • Protecting Computer Vision from Adversarial Attacks

    Advances in computer vision and machine learning have made it possible for a wide range of technologies to perform sophisticated tasks with little or no human supervision — from autonomous drones and self-driving cars to medical imaging and product manufacturing. Engineers are developing methods to keep these autonomous machines and devices from being hacked.

  • Hurricane-Resilient Wind Turbines -- Inspired by Palm Trees

    Today’s offshore wind turbines can tower more than 490 feet above ground, their spinning blades churning out up to 8 megawatts (MW) each—about enough to power 4,000 homes in the U.S. But with their increasing size comes challenges. To make those turbines more hurricane-resilient, scientists are taking a cue from nature.

  • The Chinese Military’s Access to AI Chips

    The Chinese military has made rapid progress in artificial intelligence. This progress largely depends on continued access to high-end semiconductors designed by American companies and produced in Taiwan and South Korea. The aggressive moves by the Trump and Biden administrations to limit technology exports to the Chinese military notwithstanding, China continues to order large quantities of American-designed advanced semiconductors from manufacturers in Taiwan and South Korea.

  • Collapsed Bridge Helps Inform Future Flood-Resistant Designs

    In 2018, an unprecedented flooding collapsed the Misasa Railroad Bridge, some nine miles inland from Japan’s western coast. Such infrastructure failures will continue to increase as weather events become more extreme. But we can learn optimal design needs from the catastrophic problem of failed structures.

  • NIST Announces First Four Quantum-Resistant Cryptographic Algorithms

    NIST has chosen the first group of encryption tools that are designed to withstand the assault of a future quantum computer, which could potentially crack the security used to protect privacy in the digital systems we rely on every day — such as online banking and email software.

  • Exploring Explosives for Expanding Geothermal Energy

    Geothermal energy has a lot of promise as a renewable energy source that is not dependent on the sun shining or the wind blowing, but it has some challenges to wide adoption. Sandia researchers test explosives and propellants to create geothermal power sites.

  • Winners Announced in DHS $195K Challenge to Counter Extreme Temperatures

    DHS announced the winners of the Cooling Solutions Challenge prize competition. The winners were each awarded funding, which totaled $195,000, for their innovative and creative ideas that sought climate-friendly cooling solutions to protect people in extreme heat conditions.

  • How Does the U.S. Power Grid Work?

    Responsible for powering the country and its economy, the U.S. energy grid has come under increasing strain due to climate change, and the threat of cyberattacks looms. The U.S. electric grid brings power to millions of homes and businesses via a vast network of transmission and distribution lines. Experts say the grid is increasingly vulnerable to extreme weather events, such as the February 2021 Texas winter storms, and cyberattacks. President Biden has proposed overhauling the grid, but his plans could face legal and political hurdles.

  • Researchers Simulate Defense of the Earth

    Sixty-six million years ago, a giant asteroid impact on the Earth likely caused the extinction of the dinosaurs. Currently no known asteroid poses an immediate threat. But if one day a large asteroid were to be discovered on a collision course with Earth, it might have to be deflected from its trajectory to prevent catastrophic consequences.

  • Concerns About Google AI Being Sentient

    From virtual assistants like Apple’s Siri and Amazon’s Alexa, to robotic vacuums and self-driving cars, to automated investment portfolio managers and marketing bots, artificial intelligence has become a big part of our everyday lives. No one knows when humans will create an intelligent or sentient AI, but recent revelations about LaMDA, Google’s artificially intelligent chatbot generator, raised concerns.

  • Separation and Purification of Rare-Earth Elements by Microorganisms

    Using naturally occurring and engineered proteins and bacteria, scientists will separate and purify rare-earth elements so they can be used in the defense sector.

  • Technology Can Detect Fake News in Videos

    Social media represent a major channel for the spreading of fake news and disinformation. This situation has been made worse with recent advances in photo and video editing and artificial intelligence tools, which make it easy to tamper with audiovisual files, for example with so-called deepfakes, which combine and superimpose images, audio and video clips to create montages that look like real footage.
