Prelomové objavy v zachytávaní CO₂: Pokročilé materiály a megaprojekty na odstraňovanie uhlíka zo vzduchu a priemyslu

V roku 2024 dosiahla atmosférická koncentrácia CO₂ približne 426 častí na milión, čo je asi o 50 % viac ako predindustriálne úrovne. Výskumníci z UC Berkeley vyvinuli zinkovo-hydridový MOF s názvom ZnH-MFU-4_l, ktorý dokáže zachytávať CO₂ z horúcich spalín pri 300 °C

  • Nvidia and Nokia Ink $1 Billion Partnership to Power AI-Native RAN
    October 28, 2025, 5:14 PM EDT. Nvidia and Nokia announced a $1 billion partnership to add Nvidia-powered, commercial-grade AI-RAN to Nokia's RAN portfolio, enabling AI-native 5G-Advanced and 6G networks on Nvidia platforms. The collaboration targets the AI-RAN market, projected to exceed $200B by 2030, and will enable distributed edge AI inferencing at scale. The deal includes joint testing with T-Mobile U.S. as part of the 6G innovation process. Nvidia emphasizes this as the start of an AI-native wireless era and a platform shift to maintain U.S. leadership in critical communications infrastructure.
  • Nvidia stock climbs above $200 as CEO keynote reveals AI bets and major partnerships
    October 28, 2025, 5:12 PM EDT. During Nvidia's keynote, CEO Jensen Huang outlined an ambitious AI playbook-from the Drive Hyperion robo-taxis to a global vehicle network-and a wave of partnerships. The announcements include Lilly pursuing 1,000 GPUs for drug discovery, and a Department of Energy project to deploy seven supercomputers, one with 10,000 GPUs. Additional deals with CrowdStrike and other partners reinforce Nvidia's software and security ecosystem. Huang warned the US remains ahead in AI and chips but risks falling behind without continued investment and skilled immigration. The cadence of announcements typically boosts Nvidia's stock, which is nearing a $5 trillion market cap after hitting $4 trillion in July. The move past $200 underscores investor optimism around Nvidia's AI infrastructure moat and mega-deals.
  • Tesla Signals Cybercab May Add Steering Wheel and Pedals
    October 28, 2025, 5:10 PM EDT. Tesla's chairwoman Robin Denholm said the company could equip the Cybercab with a steering wheel and pedals if required, signaling a potential pivot from the original no-steering-wheel design. The two-seat EV was introduced as a clean robotaxi intended for fully autonomous operation, with Elon Musk emphasizing a path toward autonomy and a 2026 production target. Regulators have relaxed rules for self-driving vehicles, but current exemptions cover limited cases, and Tesla hasn't solved unsupervised self-driving, leaving the Robotaxi plan in question. Tesla is setting up Cybercab production at Gigafactory Texas near Austin, viewing it as a cheaper alternative to the Model Y for its autonomous fleet. Analysts and observers note that a steering wheel might be necessary for actual volume delivery.
  • Amazon to Cut About 14,000 Jobs as It Bets on Leaner Structure and AI
    October 28, 2025, 5:00 PM EDT. Amazon announced it will cut about 14,000 white-collar roles, part of a push to be leaner-fewer layers and more ownership-to move faster for customers and growth bets. Company executives stressed the cuts aren't due to weak performance, arguing the business is performing well even as leadership doubles down on AI investments. Affected workers will receive 90 days to apply for other roles, and Reuters has flagged potential future cuts of up to about 30,000 in subsequent phases. The move mirrors a wider tech trend as major firms like Oracle, Microsoft, and Alphabet trim costs to fund AI-centric priorities while attempting to preserve profits.
  • Apple debuts RCs for watchOS 26.1, tvOS 26.1, iOS 26.1, and more
    October 28, 2025, 4:58 PM EDT. Apple has released release candidates (RCs) for its next wave of updates, including watchOS 26.1, tvOS 26.1, iOS 26.1, iPadOS 26.1, macOS Tahoe 26.1, visionOS 26.1, and HomePod 26.1 for beta testers. Public launches are expected within about a week. The big platforms bring new Liquid Glass design toggles, a broad Apple Intelligence language expansion, and the return of Slide Over on iPad. For tvOS, watchOS, visionOS, and HomePod, changes are comparatively minor. A new Apple TV app icon appears, while the TV app remains largely unchanged. Expect bug fixes, security updates, and performance improvements across the lineup as more details emerge.
