China’s Peking University Builds World’s First Large-Scale Quantum Key Distribution Network Using Photonic Chips

Modern Mechanics 24 News Desk February 14, 2026

Peking University’s Professor Wang Jianwei and Academician Gong Qihuang have built the world’s first large-scale quantum key distribution network using integrated photonic quantum chips. Published in Nature, the system connects 20 users across 3,700 kilometers, overcoming a two-decade barrier to miniaturization and proving quantum communication can move from optical benches to mass-producible silicon.

China’s Peking University Scientists Find Earth’s Core May Hold 9 Times More Hydrogen Than All Oceans

Modern Mechanics 24 News Desk February 14, 2026

Peking University’s Dr. Dongyang Huang and colleagues have discovered Earth’s core may contain 9 to 45 times the hydrogen volume of all surface oceans—0.07% to 0.36% of core weight. Using atom probe tomography, the Nature Communications study suggests Earth acquired its water during formation, not from comets, reshaping our understanding of planetary habitability.

CASC Long March-10 prototype launches from Wenchang with Mengzhou spacecraft during pad abort test; first stage performs controlled vertical splashdown.

China’s Mengzhou Spacecraft Passes High-Stress Launch Escape Test, Advancing 2030 Moon Landing

Modern Mechanics 24 News Desk February 13, 2026

China has completed a high‑stress launch escape test of its Mengzhou lunar spacecraft aboard a Long March-10 rocket at Wenchang. Conducted at max Q by CASC, the test validated independent solid‑fuel crew abort and the first controlled vertical splashdown of the booster stage. The milestone advances China’s 2030 crewed moon landing and reusable rocket technology, with a Lanyue lander already in testing and a 2035 lunar south pole station on the roadmap.

UK Scientists Fire Lasers at Darwin’s Priceless Specimens—And Solve a 200-Year-Old Mystery

Modern Mechanics 24 News Desk February 13, 2026

UK scientists have fired lasers at Charles Darwin’s 200-year-old Galapagos specimen jars to identify their unknown preservation fluids—without opening them. Led by Dr. Wren Montgomery and physicist Sara Mosca, the team used portable SORS spectroscopy to achieve nearly 80 percent accuracy, solving a major conservation challenge for the Natural History Museum London. The method, reported in ACS Omega, could protect over 100 million museum specimens worldwide.

University of Sydney researchers demonstrate liquid gallium hydrogen production using sunlight and seawater in a laboratory reactor.

University of Sydney Engineers Use Sunlight and Liquid Metal to Produce Clean Hydrogen at 12.9% Efficiency

Modern Mechanics 24 News Desk February 13, 2026

University of Sydney engineers have developed a liquid metal method that produces clean hydrogen from seawater using only sunlight. Led by Professor Kourosh Kalantar-Zadeh, the team achieved 12.9% efficiency with a circular gallium-based process. The innovation, reported in Nature Communications, solves a key problem in green hydrogen production and offers a scalable path forward.

Samsung's advanced HBM4 memory chips designed for AI accelerators.

Samsung to Launch World’s First HBM4 Mass Production Next Week for NVIDIA’s Next-Gen AI Chips

Modern Mechanics 24 News Desk February 12, 2026

Samsung will start mass-producing the world’s first HBM4 memory next week for NVIDIA’s Vera Rubin AI GPUs. This 6th-generation high-bandwidth memory, shipping after Lunar New Year, marks a key breakthrough for AI hardware, solving critical data bottleneck issues and setting a new performance standard for the next wave of generative artificial intelligence.

ETH Zurich Study Reveals Why Earth’s Chemical “Goldilocks Zone” Is So Rare in the Universe

Modern Mechanics 24 News Desk February 12, 2026

ETH Zurich scientists found a planet’s fate for life is set during its fiery birth. Their models reveal a narrow chemical “Goldilocks zone” for oxygen that allows phosphorus and nitrogen—essential for DNA and proteins—to be retained. Earth was uniquely lucky; most planets, like Mars, form outside this zone. This dramatically refines where we should search for life in the universe.

Egypt’s Arab Organization for Industrialization Unveils 1,800km Hamza-3 Suicide Drone at World Defense Show 2026

Modern Mechanics 24 News Desk February 12, 2026

Egypt’s Arab Organization for Industrialization (AOI) unveiled its Hamza-3 suicide drone with a 1,800 km range and swarming capabilities in Riyadh. Alongside the Sakr 105 rocket launcher and Haris-2 jammer, the systems highlight a push for localized production, though key components are still imported from China, mirroring a broader Arab drive for defense self-sufficiency.
