🇺🇸 US to build world’s first grid-scale nuclear fusion power plant by 2030s

Commonwealth Fusion Systems has announced plans to construct the first commercial nuclear fusion power plant near Richmond, Virginia. The plant, expected to generate 400 megawatts of clean energy, will use tokamak technology to harness fusion, which produces no greenhouse gases or long-term nuclear waste. Scheduled to achieve net fusion energy by 2026, this project represents a significant step toward limitless, sustainable power. The plant will replace a retired coal facility, supporting Virginia's clean energy transition.

🇨🇳 Chinese scientists extract uranium from seawater using candle wax in breakthrough method

Researchers at the Dalian Institute of Chemical Physics have developed a cost-effective way to extract uranium from seawater using polyamidoxime mixed with melted candle wax. This method produces porous, reusable beads capable of efficiently capturing uranium, even at its low oceanic concentration. Tests achieved absorption rates of 4.79 mg/g in real seawater and up to 8.23 mg/g in simulations. Unlocking uranium from oceans’ vast reserves could sustain nuclear power for over a millennium, addressing long-term energy demands. Published in Advanced Functional Materials.

🇸🇪 Swedish company launches Europe’s first daily commercial autonomous truck operations

Einride has begun the first daily commercial autonomous truck operations in Europe, transporting goods for Swedish pharmacy e-retailer Apotea. Operating without a driver, the truck navigates routes near public roads under a special permit, showcasing efficient, sustainable freight solutions. This milestone builds on Einride’s global expansion and partnerships, saving over 917,000 kg CO₂e for Apotea over two years and demonstrating scalable logistics technology.

🇰🇷 South Korean scientists develop swarms of magnetic ‘ant’ robots for heavy lifting and medical tasks

Researchers at Hanyang University have created ant-like microrobot swarms capable of lifting heavy objects, hurdling obstacles, and navigating fluids. Powered by rotating magnetic fields, these cube-shaped robots can self-assemble into configurations that transport cargo, unclog tubes resembling blood vessels, and guide organisms. Each 600-micrometer robot works collaboratively, enabling the swarm to tackle tasks that single robots cannot. Published in Device, this innovation shows promise for minimally invasive medical treatments and challenging industrial applications.

🇬🇧 UK researchers create human embryo 'GPS' to uncover spine development mysteries

Scientists at the Francis Crick Institute have developed human stem cell models featuring a functional notochord, a critical tissue guiding spine and nervous system formation. Inspired by studies on chicken embryos, they replicated notochord development using precise chemical signals, creating trunk-like structures resembling early human embryos. This breakthrough provides insights into spinal birth defects, chronic back pain, and neurological disorders, offering a powerful tool for developmental biology and regenerative medicine. Published in Nature.

🇩🇪 🇫🇷 German and French researchers identify vulnerability in antibiotic resistance mechanism

Scientists from TU Dresden and Institut Pasteur have discovered a weakness in the integron system, a genetic mechanism that bacteria use to exchange and store resistance genes. Using advanced optical tweezers, they found that protein-DNA complexes with weaker binding slow the acquisition of resistance. This insight could lead to supplemental treatments that destabilize these complexes, enhancing the effectiveness of existing antibiotics and offering a new approach to combating superbugs.
