"One-Way Electron Circuits" That Overturn the Premises of Physical Law──Non-Hermitian Phenomena Demonstrated in a Quantum Topological Material
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.

The grid sits at 70% idle most of the year. What AI proved with 650MW in the US—and what a 300GW forecast still needs to show
GridCARE's AI "Energize" has uncovered idle capacity in the US grid, securing over 650MW of actual connection capacity with National Grid and PGE. The 300GW figure the CEO cites, however, remains a forward-looking projection on a different scale entirely from that track record.

Quantum-Hybrid Computing That Breaks Through Supercomputer Limits Is Accelerating the Practical Use of Fusion Energy
To control tritium formation in molten salt—essential for fusion reactors to breed their own fuel—a new method combining quantum computers with classical computation has been developed. By simulating the complex behavior of electrons with high precision, it tackles the prediction of corrosive compound formation and efficient fuel recovery.

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 True Culprit Behind "Dendrites" Blocking Solid-State Battery Commercialization: MIT's New Discovery That Triples Lifespan and Charging Speed
It has been revealed that the root cause of dendrite formation, which has hampered the commercialization of solid-state batteries, lies in the "space charge layer" that forms at the grain boundaries within the electrolyte. This finding—that this region traps electrons and triggers the deposition of metallic lithium—could become a critical key to dramatically advancing the safety and performance of next-generation batteries.

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.
