💻 Technology

🇨🇳 Chinese researchers achieve world-first minimally invasive brain-computer interface restoring limb movement

Scientists at Nankai University successfully implanted a brain-computer interface (BCI) through blood vessels in a stroke patient, enabling voluntary limb movement without invasive brain surgery. The wireless system, combining interventional BCI and electrical stimulation, allowed the paralyzed man to regain functions like grasping objects, marking a major step in restoring mobility for motor-impaired patients. The trial highlights China’s rapid BCI advancement beyond existing US capabilities.

⚡️ Energy

🇨🇳 🇳🇴 Chinese and Norwegian researchers create floating solar module for offshore use with 21.78% efficiency

GCL System Integration from China and Norway's Ocean Sun have co-developed a 480W floating solar module designed to endure offshore conditions like saltwater corrosion, high humidity, and strong winds. Integrated with Ocean Sun’s patented floating platform, the NT10/60GT module achieves peak efficiency of 21.78% and uses dual-glass, frameless design to reduce costs and improve durability. This innovation supports offshore renewable energy expansion in space-limited regions while enhancing efficiency through direct seawater cooling.

🇺🇸 US company Tesla completes world’s first driverless car delivery with autonomous Model Y

Tesla has achieved the first autonomous car delivery by sending a Model Y from its Texas Gigafactory to a customer’s home, using its Full Self-Driving (FSD) system with no human or remote control. The 30-minute, driverless journey marks a logistical milestone, demonstrating potential for self-delivering vehicles despite ongoing safety concerns and regulatory scrutiny. Tesla’s move aims to boost confidence in its FSD technology and reshape vehicle distribution.

🌎 Sustainability

🇨🇳 Chinese researchers enable PEM electrolyzers to make clean hydrogen from tap water, cutting costs

Scientists at Tianjin University and partner institutes embedded an acidic molybdenum-oxide catalyst in the cathode of a proton-exchange-membrane (PEM) electrolyzer, letting it operate for 3,000 hours on ordinary tap water without degradation. The locally acidic microenvironment blocks fouling ions, matching the performance of systems that need expensive ultrapure water and pointing to cheaper, more flexible green-hydrogen production; the advance is reported in Nature Energy.

💉 Biotechnology

🇨🇳 Chinese scientists restore tissue regeneration in mice by reactivating ancient genetic repair switch

Researchers at the National Institute of Biological Sciences in Beijing enabled mice to regrow complex ear tissue by transplanting a rabbit DNA enhancer that reactivated the dormant ALDH1A2 gene, boosting production of retinoic acid - essential for regeneration. The study, published in Science, demonstrates how mammals may reclaim lost regenerative abilities, with potential medical applications in nerve, skin, and organ repair using existing FDA-approved compounds.

💊 Healthcare

🇺🇸 US researchers develop AI that detects 9 dementia types from one scan with 88% accuracy

Mayo Clinic scientists created StateViewer, an AI tool that analyzes brain FDG-PET scans to diagnose nine forms of dementia, including Alzheimer’s, with 88% accuracy. Published in Neurology, the system tripled diagnostic precision and doubled interpretation speed compared to standard methods, offering faster, scalable support for clinics lacking neurology specialists. The advance may lead to earlier, more effective interventions as dementia cases surge globally.
