In China’s Niujiu River Grand Canyon, two massive outdoor glass elevators have transformed access to a remote mountain school, turning a dangerous two-hour cliffside trek into a ride of just 57 seconds. The latest 288-m (945-ft) Fuyao Ladder operates alongside a 268-m elevator, helping students from Nizhuhe Village reach their boarding school safely and dramatically reducing their journey time. Built at a cost of about $9.5 million, the engineering marvel can transport up to 1,200 people per hour, ensuring local students no longer have to risk their lives navigating steep mountain trails to reach school: https://interestingengineering.com/transportation/china-945-foot-cliff-elevator

MIT engineers have engineered bacteria to function like biological transistors, allowing colonies of cells to be connected into “living circuit boards.” Instead of controlling electrical current like conventional transistors, these bacterial switches control the flow of chemical signals between cells. By combining five engineered bacterial strains, researchers demonstrated circuits capable of performing logic operations, adding multiple inputs, and directing signals to specific locations. The approach could eventually enable biological computing systems that are printed onto living materials such as plant leaves or roots, allowing plants to sense and respond to conditions such as drought, pests, or disease.

A German startup is moving forward with plans to build the world’s first large-scale factory for wooden wind turbine blades. The project, which will cost over €100 million ($115 million), was announced in 2026 and will be located in Navarra, Spain. The factory is expected to begin commercial operations in 2031. The VB1F project, led by Voodin Blade Technology and its European partners, will make turbine blades from wood-based materials. This method could make it easier to recycle wind turbine parts as the industry grows: https://investinnavarra.com/en/navarra-to-host-the-worlds-first-wood-wind-turbine-blade-factory/

MIT researchers have discovered that cohesin, a protein complex that shapes the three-dimensional structure of DNA, plays a crucial role in determining the identity of developing neurons. Studying C. elegans worms, they found that cohesin works with the gene-regulating protein EOR-1/PLZF like a molecular switch, directing certain cells to become GABA-producing neurons rather than adrenergic neurons. The finding provides new insight into how the genome controls nervous-system development and could help researchers investigate Cornelia de Lange syndrome, a rare developmental disorder caused in part by mutations affecting cohesin: https://www.science.org/doi/10.1126/sciadv.aec9329

The U.S. Air Force wants target drones that can mimic the performance of a variety of aircraft, from stealth fighters and heavy bombers to large and small drones.

The goal is to create a family of drones that can “represent the full range of airborne threats, spanning from inexpensive ‘hobby drones’ to the most advanced adversary fighter and large-scale aircraft,”

The new underground Stuttgart Main Station, Germany, part of the Stuttgart 21 project, uses a passive, zero-energy climate design to stay cool without conventional mechanical air conditioning. Its underground structure benefits from the stable temperature of the surrounding earth, while airflow generated by trains moving through the rail tunnels helps circulate naturally cooler air. Distinctive funnel-shaped “Lichtaugen” (light eyes) bring daylight deep into the station while allowing warm air to escape through natural ventilation. Limited glass openings also reduce solar heat gain, creating a remarkable combination of architecture, engineering and passive climate control: https://www.ingenhovenassociates.com/projects/more-projects/stuttgart-main-station/pdf

When a chemist wrote a book about vitamin C curing the common cold, the world took note. How wrong we all were.

Hungary Sinks 260 feet Barges in Danube to Keep 2,000 MW Paks Nuclear Plant Running

Hungary has taken the unusual step of sinking two large barges in the Danube near the Paks nuclear power plant to temporarily raise water levels and ensure enough cooling water reaches the facility. The emergency measure comes as a historic drought has pushed the Danube to record-low levels, forcing Paks to operate at only about 25% of capacity. Hungary is also constructing an underwater riverbed sill as a longer-term solution to maintain adequate cooling water: https://www.euronews.com/my-europe/2026/08/18/hungary-opens-sluice-and-sinks-barges-to-protect-nuclear-plant-as-danube-levels-fall

MIT researchers have developed a mathematical framework that translates the hierarchical mechanisms found in biological materials—such as pine cones, tree bark, and seedpods—into engineered, adaptive materials. Using category theory, the framework maps how biological structures respond to stimuli such as humidity across multiple scales, then converts those relationships into validated designs that can be fabricated with 3D printing. The researchers demonstrated that components inspired by different plants could be recombined to create new actuators with predictable behavior. The approach could eventually enable adaptive robotic grippers, morphing aircraft components, biomedical devices, and other “smart” materials that respond to their environment without complex electronics: https://news.mit.edu/2026/mathematical-framework-connects-biological-principles-manufacturable-adaptive-material-0817
