Nanotubes hint at room temperature superconductivity

Researchers have noted apparent superconductivity effects when applying magnetic fields to carbon nanotubes at room temperature and above. This could result in faster, lower-power electronics and the ability to carry electricity across long distances with 100 per cent efficiency.
Guo-meng Zhao and Yong Sheng Wang of the University of Houston put a magnetic field across a bundle of carbon nanotubes at temperatures up to 400 kelvin (127°C). The bundle generated its own weak, opposing magnetic field, which can be a sign of superconductivity.
