According to Science Alert, new research explores the theory that advanced alien civilizations might become "invisible" to us due to their use of sophisticated artificial intelligence (AI) and advanced communication technologies. The study builds on Carl Sagan's earlier concept of the "communication horizon," suggesting that as civilizations evolve, their communication methods may surpass human detection capabilities. The paper posits that technological progress—especially in AI—could render extraterrestrial signals undetectable within mere decades. This hypothesis adds a fresh perspective to the enduring mystery of the Fermi Paradox, which questions why humanity has yet to find evidence of intelligent life despite the high probability of its existence. While the theory remains speculative, it underscores the challenges posed by the rapid evolution of technology in both understanding and possibly emulating other intelligent species. Source 1

Tech Radar reports on the initiative spearheaded by Meta, Nvidia, and other major tech companies to develop Ethernet for Scale-Up Networking (ESUN), an open standard for AI cluster communication. This move challenges the dominance of proprietary InfiniBand systems, which currently lead in high-performance AI networking. Proponents argue that Ethernet's simplicity and cost-effectiveness could revolutionize infrastructure for large-scale data centers. However, questions remain about whether this open approach can deliver the reliability and performance required for complex AI workloads. This initiative reflects broader shifts in AI technology toward accessibility and collaboration, though the transition from proprietary systems like InfiniBand may face significant hurdles.

Tech Radar reveals that Android apps designed for the new Samsung Galaxy XR headset, also known as Project Moohan, have started appearing on the Google Play Store ahead of the device's anticipated unveiling on October 21. The apps suggest a mix of virtual reality (VR) and augmented reality (AR) experiences, similar to offerings by competitors like the Meta Quest 3. With a rumored starting price of approximately $1,760, the headset is expected to include advanced AI capabilities such as live translations. This development highlights the growing competitive landscape of extended reality (XR) devices, though adoption may be limited by high costs and market saturation. Source 38

Tech Radar reports that Oracle has announced the launch of the OCI Zettascale10, claiming it as the largest AI supercomputer in the cloud, capable of delivering 16 zettaFLOPS of peak performance. The system integrates 800,000 Nvidia GPUs and features advanced networking architecture to enhance scalability and efficiency. Oracle projects that this infrastructure will support AI developments such as OpenAI's Stargate cluster. However, experts caution that independent verification of Oracle's performance claims is still pending, and the practical implications of such massive computational power raise questions about cost and real-world use cases.

Tech Radar highlights the debut of Broadcom's Thor Ultra, the first 800G Ethernet Network Interface Card (NIC) designed for AI data centers. Using PCIe Gen6 x16, the card aims to address inefficiencies in traditional networking protocols, such as RDMA, by introducing advanced features like packet-level multipathing and enhanced congestion control. Broadcom’s commitment to open standards aligns with industry trends favoring interoperability, but the card's adoption may hinge on its ability to justify costs in non-specialized environments. This innovation underscores the escalating demand for robust network solutions as AI workloads grow increasingly complex. Source 35

Researchers at the University of Cambridge have developed hematoids, lab-grown clusters of cells capable of producing human blood stem cells, reports Science Alert. These structures could potentially reduce dependence on blood donations for treating disorders such as leukemia. Unlike previous methods, hematoids show enhanced self-sufficiency, producing red and white blood cells within two weeks. While still in early stages, this breakthrough holds promise for advancing regenerative medicine and improving drug testing methodologies. However, significant challenges remain before clinical applications can be realized. Source 7

Politico Europe reports on comments by Christine Lagarde, President of the European Central Bank, who highlighted the long-term impacts of U.S.-China tariffs on global trade. Speaking on CBS's "Face the Nation," Lagarde noted that exporters and importers have absorbed costs so far, but rising consumer prices could be imminent. She also emphasized how artificial intelligence is reshaping industries alongside trade realignments. While trade wars often aim to protect domestic interests, they risk destabilizing global supply chains, potentially exacerbating inflation and hampering economic growth. Source 14

Politico Europe reports that Ukraine aims to accelerate its EU membership process, with Deputy Prime Minister Taras Kachka expressing optimism about overcoming Hungary's veto by December. Hungary’s opposition, rooted in fears of destabilization and competition, contrasts with growing EU support for Kyiv. Proposed solutions include granting new entrants limited voting rights to alleviate concerns among current members. If resolved, Ukraine's accession could signal a significant geopolitical shift, though challenges remain in balancing member state interests. Source 31
