- Title
Arsenic heats up iron superconductors.

- Abstract
The article reports that researchers at the Tokyo Institute of Technology in Japan, has synthesized a new superconductor based on iron rather than copper. The material also featured oxygen, lanthanum and phosphorus, but its transition temperature was just 4 degrees above absolute zero, no better than the very first superconductor discovered a century before. The iron-based family might provide a fresh opportunity to engineer superconductors that operate at practical temperatures. It also offers chemists a chance to finally figure out how high-temperature superconductors work.
