Superconducting at up to 140 degrees Fahrenheit has been demonstrated at the U.S. National Accelerator Laboratory, but the catch to room temperature superconducing today is that it only lasts for pico-second pulses, but they hope to extend the time to DC: R. Colin Johnson @NextGenLog and EE Times.
Laser causes oxygen atoms (red) to vibrate between layers of copper (blue) oxide that are just two molecules thick in a common high-temperature superconducting material known as YBCO in a way that
likely indicates superconductivity.
