Physicists at MIT have spotted the second sound of a superfluid. Besides being pleasantly alliterative, the phenomenon may explain how heat moves through certain rare materials on Earth and deep in space.
A few short weeks ago, the world was taken aback by claims of a room-temperature superconductor—a scientific finding that could redefine modern physics as we know it. Those claims turned out to be bunk, and a South Korean university is investigating a complaint made against the professor who published them in a paper.

For over a century, scientists have sought a holy grail of materials: a room-temperature superconductor, a material that can carry electrical charges without resistance, which would revolutionize the energy landscape as we know it.
