A tiny time difference spanning just a few instructions arises immediately after the latest security mechanism resets a processor's branch predictor. An MIT research team has demonstrated a new attack technique that triggers an interrupt into this physical gap to leak confidential data.
BTQ and ITRI verified QCIM for post-quantum cryptography in TSMC's 28nm design environment. Not an actual measurement of a completed chip, customer evaluations that BTQ expects by year-end mark the next hurdle for confirming performance.
The reported up-to-$3 billion NVIDIA investment in Lancium and Amazon's acquisition of the GW Ranch project in Texas show that AI investment has moved toward securing grid interconnection and dedicated power generation.
Google DeepMind has released WeatherNext Cyclones, which simultaneously forecasts the track, intensity, and wind field of tropical cyclones. While it reports an average lead advantage of more than one day, it also lays out the operational conditions of the open model and its boundaries with official warnings.
The price per gigabyte of memory has spiked back to 2007 levels, reversing a half-century-long exponential decline in just a matter of months. While AI-driven HBM demand is expanding at an annual rate of 200%, supply growth remains stuck at around 20%, and the effects are already spilling over to consumers through price hikes on game consoles and PCs.
A team led by Peking University has grown ABC-stacked rhombohedral graphene with over 99% phase purity, reaching up to 160×80µm. Practical use in quantum chips still requires larger-area growth and independent replication.
KAIST has developed a memtransistor whose response speed can be non-volatilely programmed, reducing the prediction error for signals containing multiple mixed frequencies by a factor of 40. This achievement overcomes the long-standing constraint of physical reservoir computing—the inability to change the time response after fabrication—through a dual-layer gate structure.
A test configuration of RTX Spark with 18 cores and 5,120 GPU cores has appeared in Geekbench 7. Reading the performance gap against the 20-core version and the limits of a single benchmark run, we examine the product tiers NVIDIA may be considering.
Bloomberg reports that Apple is considering an Apple Watch redesign that could include round displays and a screenless device. This fall's update will be iterative, with a future focus on rebuilding the health data experience.
Across six LLMs assigned occupational roles, compliance rates with inappropriate requests from a higher-status role rose by 2.0 to 3.7 percentage points. The findings are limited to synthetic English dialogues, and questions remain about statistical procedures and reproducibility.
