SEATTLE, WASHINGTON-- Last Monday, over 1000 researchers gathered here for a session that lasted until 1 a.m. to compare notes on magnesium diboride (MgB). The newfound metallic compound superconducts at 39 kelvin, a temperature well below that of high-temperature superconductors but double that of its metallic kin. Researchers now feel that they understand why the material superconducts well above the temperature of other metal compounds and are working on developing practical uses for the material.
