Microsoft has released Aurora 1.5, featuring 22 variables, hourly intervals, and probabilistic ensembles. It reduced typhoon track errors by up to 34% compared to the previous version, but intensity, precipitation, and comparisons with current AI models remain unverified.
A POSTECH research team announced that it has stably stacked more than 10 layers of 14-micrometer-thick silicon chips using low-temperature, low-pressure bonding. Compared at the same package height as 12-layer HBM, the team confirmed roughly 4x the density, but the demonstration was limited to test chips without DRAM circuitry, and integration into actual HBM or yield data have not yet been presented.
In next-generation sodium metal batteries, a research team has introduced a unique design combining two salts, successfully achieving both electrolyte robustness and high-speed ion conduction. This breakthrough overcomes conventional technical barriers such as ultra-fast charging and long cycle life, marking major progress toward practical application.
A Swiss research team has achieved a power conversion efficiency of 30.02% with a triple-junction solar cell stacking silicon and perovskite, breaking through the theoretical limit of a single material. The fusion of low-cost materials and nanotechnology is paving the way to bring ultra-high-efficiency power generation—once confined to space exploration—down to Earth.
To overcome the scaling limits of silicon, a new technology has been developed for synthesizing single-crystal molybdenum disulfide at wafer scale. Through self-aligned crystal growth and an automatic thickness self-limiting mechanism, an atomically thin semiconductor film with extremely few defects has been realized, marking a major step forward in the practical implementation of next-generation devices.
China Three Gorges Corporation has begun trial operation of a 1GW integrated PV-plus-CSP project in Xinjiang Uyghur Autonomous Region. On top of 900MW of solar PV, surplus electricity and solar heat are stored in molten salt to deliver 100MW of output at night, helping stabilize the power grid.
Three U.S. startups have successively revealed commercial contracts and demonstration plans for space-based solar power, while NASA's independent estimates swing by roughly 20-fold depending on assumptions. The industry's targets align almost exactly with the best-case scenario in those estimates, leaving feasibility hinging on verification of launch costs and power-transmission efficiency.
Ocean engineering company DEEP has installed a crewed undersea habitat on the seafloor off the coast of Florida, entering the final phase of verifying the entire system. By leveraging saturation diving, the facility enables extended coral reef research with reduced decompression burden, aiming to accumulate operational records toward the development of future large-scale facilities.
A research team used a quantum anomalous Hall insulator to realize, inside a solid-state material, a theoretical model of non-Hermitian physics in which electrons flow in only one direction. They demonstrated the "skin effect," in which electrons pile up at a specific edge as boundary conditions change, a finding expected to contribute to the development of next-generation quantum devices.
