December 10, 2025, 10:34 PM EST. AMD unveils Redstone, its new iteration of AI-powered upscaling, aiming to rival Nvidia's DLSS. The update blends enhanced AI upscaling with a machine learning-powered frame generation pipeline and improvements to latency and visual quality. Building on the FidelityFX Super Resolution (FSR) family, Redstone adds frame generation and signals support for multi-frame generation and frame interpolation to push low-resolution renders toward 4K with higher perceived FPS. AMD points to smoother scenes (e.g., F1 24) compared with older versions that showed artifacts. While Nvidia's DLSS 4 and Intel's XeSS 2 push similar ideas, Redstone is currently tied to newer AMD GPUs (and could influence consoles). AMD claims large FPS gains-from the mid-20s to over 100 fps in some cases-though recommends maintaining a stable base frame rate to avoid artifacts.

December 10, 2025, 10:18 PM EST. Israeli quantum computing startup Quantum Art closed a $100 million Series A to accelerate commercialization and achieve quantum advantage. Led by Bedford Ridge Capital, the round counts new investors such as Battery Ventures, Destra Investments, Lumir Growth Partners, Disruptive AI, plus others, bringing total funding to $124 million. The proceeds will speed development of Perspective, the firm's 1,000-qubit multi-core system, and prototyping of a third-generation 2D architecture targeting thousands of qubits. Its architecture uses reconfigurable multi-core trapped-ion chains to preserve connectivity, enabling up to 100x more gates per second and a 50x smaller footprint versus some roadmaps. Milestones include a 200-ion chain demonstration and collaborations with NVIDIA CUDA-Q and Ayalon Highways.

December 10, 2025, 10:02 PM EST. The Energy Department's coming science agenda centers on emerging technologies, with leadership aligning to boost the U.S. edge in AI and related fields. Undersecretary Darío Gil framed the Genesis Mission as an integrated discovery platform that links national laboratories, academia, and industry to accelerate AI applications on the nation's high-performance computers. A first funding tranche of about $320 million supports the American Science Cloud and the Transformational Model Consortia to curate data sets for training new models. DOE seeks to build the Genesis platform while pursuing a portfolio of challenges across energy, national security, and discovery science. The plan also foregrounds quantum computing integration and backs the National Quantum Initiative Act Reauthorization.

When you start a wireless CarPlay session, your iPhone first uses Bluetooth to establish a secure link and request permission, then Wi-Fi takes over to create a dedicated network for data syncing and smooth app performance. Some cars require a wired USB connection, while others support wireless CarPlay or both. Even with wired CarPlay, you'll still want cellular data enabled for navigation, music streaming, and connected features. Earlier CarPlay models rely on a cable, but you can add wireless CarPlay with an adapter. Advantages of wired include reliability and charging, while wireless offers convenience.

December 10, 2025, 9:48 PM EST. Tesla's new Charging Passport in the app turns 2025 into an end-of-year stats reel for EV drivers. It maps Supercharger visits, highlights badges for iconic sites or milestones, and surfaces metrics like longest trip, favorite stations, miles added, and fuel savings. The program also offers a prize pool: nine owners can win free Supercharging for life, provided they rank in the top three for (1) highest total energy charged in 2025 (kWh), (2) most unique Supercharger sites visited, and (3) longest distance between visited sites. Requirements include app version 4.51.5+, at least three unique sites, and vehicle software 2021.4425+. Check Charging Passport now to view your 2025 milestones.
