  • The Accidental Engineer Who Conjured Up Extended Reality August 19, 2025
    In the 1980s, people weren’t wearing head-mounted cameras, displays, or computers. Except for high school student Steve Mann, who regularly wore his homemade electronic computer vision system (seeing aid).Back then, Mann attracted stares, questions, suspicion, and sometimes hostility. But it didn’t stop him from refining the technology he developed. It now underlies augmented-reality eyeglasses—including those […]

  • The AI Agents of Tomorrow Need Data Integrity August 18, 2025
    Think of the Web as a digital territory with its own social contract. In 2014, Tim Berners-Lee called for a “Magna Carta for the Web” to restore the balance of power between individuals and institutions. This mirrors the original charter’s purpose: ensuring that those who occupy a territory have a meaningful stake in its governance.Web […]

  • Is the World Adopting Post-Quantum Cryptography Fast Enough? August 13, 2025
    A year ago today, the National Institute of Standards and Technology (NIST) published the first-ever official standard for post-quantum cryptography (PQC) algorithms. The standard was a result of a 2022 memorandum from the Biden administration that requires federal agencies to transition to PQC-based security by 2035.Cryptography relies on math problems that are nearly impossible to […]

  • Meta’s New Flat-Panel Laser Display Is Ultrathin August 20, 2025
    By shining lasers onto a tiny screen roughly as wide as a pencil-top eraser, scientists at Meta have created an ultrathin, high-definition flat-panel display they suggest might be used in augmented reality applications. Flat-panel displays are now commonplace, often illuminated by LEDs. When contemplating the next step beyond these displays, scientists have explored replacing the […]

  • Semiconductor Rivalry Rages on in High-Temperature Chips August 11, 2025
    This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore. Two semiconductors—silicon carbide and gallium nitride—are the rivals in a (quite literally) heated competition to make circuits capable of performing at the highest temperatures. Silicon carbide chips had taken the lead, operating at 600 °C. But gallium nitride, which […]

  • Protecting Electronics Against Electrostatic Discharge August 5, 2025
    Today’s semiconductor devices are built with nanometer-scale features and operate at increasingly lower voltages—which makes them more susceptible to even minor electrical overstress.Electrostatic discharge (ESD) is a persistent, costly challenge in the electronics industry. A discharge of just 100 volts can degrade or destroy sensitive components designed to operate at voltages as low as 1.2 […]
