• OpenAI entwickelt ein Smartphone, dessen Produktion 2028 anläuft und bei dem KI-Agenten für US-Verbraucher traditionelle Apps vollständig ersetzen sollen. • Das Gerät steht vor potenziellen Hürden durch globale Speicherengpässe, die den Rollout verzögern oder gefährden könnten. • Dieser Durchbruch könnte die von Google und Apple dominierten mobilen Ökosysteme disruptieren und Benutzeroberflächen neu definieren.

The chief of the ​District of Columbia police department said investigators believe the suspect was a guest at the Washington Hilton hotel, where the annual dinner was ​taking place, but that no motive had been determined.

• Researchers at the University of Washington created an artificial photosynthesis prototype converting sunlight directly into storable chemical fuels with 13% efficiency, surpassing previous laboratory records of 8-10%. • The system uses engineered nanostructures and novel catalysts to split water and fix carbon dioxide, producing methanol as a liquid fuel suitable for existing energy infrastructure, detailed in Nature Energy on April 21. • The breakthrough could enable large-scale production of carbon-neutral synthetic fuels without competing for agricultural land, addressing both climate and energy security challenges.

• MIT scientists unveiled a new quantum computing design achieving stable operation of 1,024 qubits simultaneously, surpassing previous records and demonstrating significant error correction capabilities reported on April 21. • The innovation uses a novel topological qubit design with error rates of 0.1% per operation, enabling computations previously impossible due to quantum decoherence, according to research published in Physical Review Letters. • The breakthrough could accelerate commercial quantum computing applications in drug discovery, materials science, and optimization problems within 2-3 years, researchers said.

• Meta released Llama 4 on April 20, 2026, a 2 trillion parameter multimodal AI model trained on 15 petabytes of US-centric data. • The model outperforms GPT-4o on benchmarks like MMLU (92% score) and supports vision-language tasks for enterprise apps. • Open-sourcing aims to spur US AI innovation, with downloads exceeding 500,000 in first hours via Hugging Face.

• Brookhaven National Laboratory researchers created superconducting quantum interference devices (SQUIDs) using transition metal silicides, compatible with silicon manufacturing processes. • The technique adapts standard electronics methods, marking a milestone for scalable quantum systems on April 14, 2026. • This bridges gaps in quantum computing hardware by enabling integration with existing semiconductor fabs.

Engine-maker CEO hails ‘critical milestone’ for company in race to deliver SMR technology built at Wylfa plant on Anglesey Business live – latest updatesRolls-Royce has secured up to £599m from Britain’s national wealth fund as it races to develop the UK’s first small modular nuclear reactors.The fund will help support Rolls-Royce’s design of small modular reactors (SMRs) at Wylfa on the island of Anglesey (called Ynys Môn in Welsh).
