Researchers discovered two new metastable ice phases (ices XXI and XXII) that crystallize directly from deeply supercooled liquid water using emulsified water samples. These phases exhibit complex crystal structures with high unit cell contents and provide experimental validation for previously predicted computational models, helping bridge gaps between theoretical and experimental understanding of water's phase diagram.
A Show HN post describing Jev Approach Control, an air traffic control simulation or tool for managing aircraft arrivals on Runway 27 with specific vectoring and clearance procedures.
Supra is a parametric CAD platform for designing physical systems—mechanical parts, electronics, and structures—with integrated simulation (stress, thermal, airflow), design optimization, and automated verification. It generates production-ready outputs (STEP, STL, BOM, firmware) and tracks design intent, constraints, and risk through the full development cycle.
A FIRE calculator tool that simulates day-by-day finances to age 112, determining how long you need to work at a high salary before you can coast, stop working, or retire without depleting your nest egg. It accounts for taxes, expenses, investments, and offers scenarios like relocating cities, adjusting partner income, and optimizing retirement accounts.
Ace Combat 8: Wings of Theve launches October 2 as the first mainline entry in seven years, emphasizing accessibility through an extended tutorial and immersive first-person cockpit perspective. The game combines dogfighting simulation with tactical warfare elements, offering players customization of jets, weapons, and squad loadouts to create visceral aerial combat experiences.
