    ETRI develops AI-powered intelligent 6G radio access technology that significantly enhances wireless communication performance

    Korea’s research community has reached an important milestone on the path toward next-generation mobile communications with the development of a technology platform that brings the 6G era closer. Researchers expect that AI-Native mobile networks, in which artificial intelligence autonomously controls and optimizes the communication system, could achieve transmission efficiencies up to 10 times higher than those of 5G.

    Breakthroughs in AI-based wireless access
    ETRI has completed the development of AI-based wireless access technology (AI-RAN), a core foundational technology for the 6G era, and has achieved significant results in paving the way for the AI-based next-generation mobile communication era.

    The biggest feature of this technology is that it has applied AI to wireless tran...

    Sudden breakups of monogamous quantum couples surprise researchers

    January 5, 2026, Categories  Physics, Technology/Electronics

    two layers of a chemical structure lie above each other with black balls hovering on top. On the top layer, there is a cyan ball with a white ball in the corresponding layer below
    An exciton forms when an electron pairs up with a hole—a mobile particle-like void in a material where an electron is missing from an atom. When paired up as an exciton, a hole and electron normally travel around together as an exclusive couple, but a new experiment probes what happens when conditions in a material break up the pair. In the image, a hole (grey sphere) resides in the bottom layer of a stacked material and is paired to an electron in the top layer (cyan sphere). None of the electrons present in the top layer (black spheres) are willing to share a spot in the material with each other or the electron in the exciton. (Credit: Mahmoud Jalali Mehrabad/JQI)

    Tiny tech, big AI power: What are 2-nanometer chips?

    January 3, 2026, Categories  Physics, Technology/Electronics

    Only a few companies are able to produce 2-nanometre chips, including Taiwan's TSMC, which dominates the industry
    Only a few companies are able to produce 2-nanometer chips, including Taiwan’s TSMC, which dominates the industry.

    Taiwan’s world-leading microchip manufacturer TSMC says it has started mass producing next-generation “2-nanometer” chips.

    AFP looks at what that means, and why it’s important:

    What can they do?
    The computing power of chips has increased dramatically over the decades as makers cram them with more microscopic electronic components.

    That has brought huge technological leaps to everything from smartphones to cars, as well as the advent of artificial intelligence tools like ChatGPT.

    Advanced 2-nanometer (2nm) chips perform better and are more energy-efficient than past types, and are structured differently to house even more of the key components known as transistor...
