Why Rare Earths from Companies Backed by $3 Billion from the US Department of War Are Heading to Japan and South Korea

MP Materials, Energy Fuels, and Phoenix Tailings secured more than $3 billion combined in government loans and M&A in June 2026, but the main buyers of their output are Japanese companies via Sumitomo Corporation of Americas and South Korean manufacturers. US neodymium magnet production capacity remains under 1,000 tons per year.

The "Light Fingerprint" Hackers Can't Steal: A Next-Generation Laser Authentication Technology That Eliminates IoT Vulnerabilities at Their Root

A research team at KAUST has developed a next-generation optical authentication system that combines the unpredictable chaos generated by lasers with AI. By never storing a physical key in memory and instead generating a "light fingerprint" only at the moment of authentication before letting it vanish, the system can withstand both quantum computers and physical attacks.

Freeze the Operation in Spacetime: The Historic Moment a University of Tokyo Team Proved 'Quantum Memory Beats Classical Memory'

A research team at the University of Tokyo has proven that, in the technical challenge of storing and retrieving unknown quantum operations, quantum memory mathematically surpasses classical memory. For isometry operations in which the dimension of information increases or decreases, the team showed that while classical strategies remain bound by the standard quantum limit, quantum strategies exploiting entanglement can store operations with far greater efficiency—opening a new frontier in quantum information science.
