Latest science news: breakthrough research in physics, chemistry, and climate science — major scientific discoveries explained for everyone.
Quantum error correction combines many noisy physical qubits to protect a logical qubit. Learn how syndrome measurements, surface codes and thresholds address noise, and why laboratory progress is not yet universal quantum advantage.
Sodium-ion batteries replace lithium ions with sodium ions. Learn how cathodes, hard-carbon anodes and electrolytes work, where the chemistry may fit, and why no battery is best for every application.
Structural batteries combine mechanical load-bearing and electrochemical storage in one composite system. Learn the materials science, accounting challenges, prototypes and limits behind the idea.
