Can Digital Twins Stop California’s Next Flood? Researchers Say Yes

On the night of March 11, 2023, the Pajaro River in central California burst its levees, flooding strawberry fields and homes just miles from the town of Pajaro. Residents awoke to water rushing through their houses, a stark reminder of the state’s growing flood danger as climate change brings heavier rains. Scientists are now turning to “digital twins” – realistic computer copies of real‑world places – to predict and prevent such disasters. In Europe, teams at VRVis GmbH have built digital twins that model rivers, streets and neighborhoods, letting officials test how different storm scenarios would play out. A research group at the University of California, Berkeley wants to bring the same technology to California, layering climate projections, land‑use data and social‑equity maps into a single virtual sandbox. By running countless “what‑if” simulations, planners could spot vulnerable communities, design smarter levees and issue earlier warnings. The goal is not just to forecast water levels but to ensure flood protection measures are fair and effective for everyone, especially those historically left out of disaster planning. If successful, digital twins could become a vital tool in the state’s fight against rising flood risks.

How Ancient Maltese Sailors Used the Night Sky to Cross the Mediterranean

New research reveals that the prehistoric people of Malta weren’t just island dwellers—they were skilled navigators who charted the seas by starlight. Archaeologists examined stone temples and burial sites, noting a consistent pattern that links their cultural practices to a sophisticated understanding of time and direction. The breakthrough came from a surprising source: tiny shards of volcanic glass, or obsidian, found on both the Maltese island of Pantelleria and Sicily. Because obsidian only forms in specific volcanic regions, its presence confirms that ancient Maltese voyagers made regular trips across the Mediterranean. By mapping the positions of constellations that would have been visible from these islands, scientists argue that the seafarers used the stars as a natural compass, guiding their boats long before modern navigation tools existed. This discovery not only reshapes our view of Malta’s early societies but also highlights how early humans harnessed the night sky to explore, trade, and connect distant cultures. The findings underscore the ingenuity of our ancestors and open new avenues for studying ancient maritime routes worldwide.

North Korean Hackers Tricked Google with Fake Jobs – Inside the ‘Dream Job’ Scam

Security researchers have uncovered a sophisticated recruitment scam run by the Lazarus Group, a hacking outfit backed by North Korea. The operation, dubbed “Operation Dream Job,” lures professionals with glossy job ads that look like they’re from top‑tier companies such as Lockheed Martin and Enveil. What’s shocking is that these bogus postings slipped past Google’s filters and even appeared at the very top of search results, making them look completely legitimate. The scammers build a full‑blown fake company – complete with a polished website, LinkedIn page, and fabricated employee profiles – then reach out to potential victims with promises of high salaries, great benefits, and exciting projects in fields like aerospace and defense. Once a target bites, the attackers use a newly discovered Windows vulnerability (CVE‑2026‑68820, a “use‑after‑free” bug) to gain deeper access to the victim’s computer, often installing a hidden webshell that lets them control the system remotely. Beyond stealing personal data, Lazarus uses the scheme to hijack cryptocurrency wallets and funnel the proceeds into North Korea’s weapons program. The discovery highlights how even major tech giants can be duped by well‑crafted social engineering, underscoring the need for tighter verification of online job listings and heightened vigilance among job seekers.

Why Chinese AI Models Are Winning Globally: Power, Price, and Open‑Source Edge

Chinese artificial‑intelligence models are making headlines worldwide because they deliver strong performance at a fraction of the cost of Western alternatives. Developers from North America, Europe, Southeast Asia and Latin America report that switching to Chinese large‑language models slashes their computing and operational bills, letting projects that were once too expensive finally get off the ground. Two factors drive this appeal. First, Chinese teams have embraced a “Mixture‑of‑Experts” (MoE) design that activates only a small set of specialized sub‑networks for each request, cutting power use while keeping output quality high. Second, a thriving open‑source culture means many models are released with open weights, inviting developers worldwide to spot bugs, add features and adapt the technology to local languages and industries. The results are evident in usage statistics: Chinese models dominate weekly call volumes on platforms like OpenRouter, and China accounts for 41 % of all monthly model downloads on Hugging Face, surpassing 10 billion downloads. Industry leaders such as NVIDIA’s Jensen Huang and Tesla’s Elon Musk have publicly praised these models. Behind the scenes, China’s massive data‑center capacity, green power supply and domestically produced chips keep hardware costs low, while continuous engineering tweaks—low‑precision quantization, caching tricks and pipeline optimizations—further trim expenses. The combination of cost‑effective architecture, open‑source momentum and robust infrastructure is turning Chinese AI models into a go‑to solution for businesses and creators around the globe.

Space Buses Set to Boom: 20‑Fold Growth Expected as China Joins the Race for In‑Orbit Services

China’s reusable‑rocket breakthrough – the successful recovery of the Long March 10B first stage – has lowered launch costs and shifted the commercial space race from simply getting payloads into orbit to providing full‑service, in‑orbit logistics. The new “space bus” or Orbital Transfer Vehicle (OTV) can pick up multiple satellites that share a launch, then ferry them to their final orbits, refuel them, or even clean up debris. Globally, three OTV business models are taking shape: multi‑satellite deployment across different orbits, on‑orbit extension and refueling, and space‑debris removal. Companies such as Italy’s D‑Orbit, the U.S. firm Space Logistics, and Japan’s Astroscale have already proven these concepts with dozens of missions and, in Astroscale’s case, a stock‑market debut. In China, the market for OTV services is projected to hit 200 billion RMB between 2026 and 2035, driven by the need to replenish large satellite constellations and launch thousands of small satellites via “car‑pool” rides. Start‑ups like Infinite Aerospace (IH‑1), Future Aerospace (Space 4S Shop), Guoyu Xingchen and Sanyuan Aerospace are racing to secure a slice of this fast‑growing pie, leveraging reusable‑rocket expertise, deep aerospace know‑how and strong ecosystem ties. As launch providers such as LandSpace, CAS Space and others gear up for IPOs, the next frontier of commercial aerospace will be the in‑orbit services that turn space into a true transportation network.

China Dominates the Humanoid Robot Market, Shipping Over 97% of the World’s Units in H1 2026

A new industry report shows that China is now the undisputed leader in the global humanoid‑robot market. In the first half of 2026, about 19,100 humanoid robots were shipped worldwide – more than three times the volume a year earlier – and Chinese manufacturers accounted for over 97% of those units. The biggest player, Zhiyuan Robot, delivered roughly 8,400 machines, giving it a 44% share of the global market and the top spot worldwide. Close behind, Unitree shipped about 5,900 robots, capturing 31% of the market. Together, these two firms outpace the leading U.S. companies by a wide margin. Smaller Chinese firms also made a mark: Galbot, UBTECH and Leju contributed 5%, 4% and 3% of global shipments respectively. Most of the robots – more than 70% – are being used in factories and commercial settings, a sharp rise from the 50% share recorded at the same time last year. Analysts expect the total number of robots shipped in 2026 to reach around 60,000, and they forecast a surge to half a million units by 2030 as the technology becomes more affordable and versatile. The rapid growth underscores China’s strategic push to lead in advanced robotics and signals a major shift in how industries worldwide will automate their operations.

China Fast‑Tracks 6G: Licenses Granted, Pilots Launched, Commercial Rollout Expected by 2030

China’s next‑generation mobile network is moving from the lab to the streets faster than anyone expected. In May, the Ministry of Industry and Information Technology gave the IMT‑2030 Promotion Group permission to use the 6 GHz band for 6G testing, and by June a nationwide pilot program linking provinces and cities was underway. Jiangsu Province formed a 6G industry alliance, while Hubei released a detailed action plan to boost local development. These steps mark the transition from theory to real‑world trials, allowing engineers to test signal penetration, interference and device performance in urban and industrial settings—much like moving a self‑driving car from a closed test track onto public roads. China’s 6G roadmap is divided into three phases: key‑technology trials, technical‑scheme trials, and system‑networking trials. The first phase is complete, the second has begun, and commercial services are slated for around 2030. The push is backed by strategic planning: the 2023 Radio Frequency Allocation Regulations earmarked spectrum for 6G, and the country’s five‑year plans stress coordinated infrastructure upgrades. Existing 5G networks will not be abandoned; researchers are already proving that 6G‑level performance can be achieved on current 4G/5G links using semantic communication. Overall, China’s disciplined approach—clear timelines, coordinated pilot zones, and spectrum foresight—suggests a steady march toward a 6G era that could reshape everything from remote work to rural connectivity.

China’s Xinyuenneng Races Ahead in Silicon‑Carbide Chip Production, Aiming to Power the Next‑Gen EV Boom

Guangdong Xinyuenneng Semiconductor, a high‑tech firm based in Guangzhou’s Nansha district, is rapidly becoming China’s flagship producer of automotive‑grade silicon‑carbide (SiC) chips. Established in 2021 when over 95% of high‑voltage (800 V+) SiC chips for electric‑vehicle (EV) drives were still imported, Xinyuenneng set out to build a domestic supply chain. The company follows a dual‑track strategy: it first secured batch orders in industrial‑control and consumer markets, while simultaneously pouring resources into research for EV power‑train chips. The approach paid off. After a surge in AI data‑center and NEV demand in late 2025, Xinyuenneng’s order book more than doubled in the first half of 2026, and its factories are running at over 80 % capacity. Its third‑generation planar‑gate MOSFETs already surpass the latest global mass‑production standards, and its second‑generation trench‑gate devices match international leaders, earning the 2026 IC Rankings “Annual Automotive Chip Technology Breakthrough” award. Construction speed is another highlight: the Phase I fab was commissioned in just 15 months, a record for large‑scale Chinese chip plants. Nansha’s “dual‑zone overlay” policies, free‑trade‑zone incentives, and a full‑chain semiconductor ecosystem have helped the company achieve 100 % equipment connectivity and AI‑driven defect detection. With over 600 staff, strong university collaborations, and plans for an IPO within two years, Xinyuenneng aims to supply SiC chips for major Chinese automakers such as Geely, Leapmotor and Dongfeng Nissan, and to expand into AI data‑centers, solid‑state transformers and solar storage. The firm sees SiC demand exploding before 2030 and positions itself as a benchmark for green, AI‑enhanced chip manufacturing in China.
