USC engineers have built a memory chip that runs at 700°C, hotter than molten lava and 500 degrees beyond what conventional electronics can tolerate. The memristor uses a stack of tungsten, hafnium oxide, and graphene to block the metal migration that normally kills hot chips. Beyond Venus landers and geothermal drilling, the device could slash the energy AI systems burn on matrix multiplication and cooling, with billion-cycle endurance already demonstrated.

While Brent crude swings near $100 and the Strait of Hormuz stays half-closed, China quietly flew the world's first megawatt-class hydrogen turboprop. The 16-minute test of the AEP100 engine over Zhuzhou burned liquid hydrogen directly in a turbine cycle, the path Airbus abandoned in 2025 when it pushed ZEROe to the 2040s and dropped combustion entirely. Beijing now leads a race the West has slowed down on.
