A microfluidic system with channels lined with magnetic liquids can ease the flow of samples and safely transport delicate cells, possibly helping to miniaturize microfluidic devices (Nature 2020, DOI ...

The discovery of superconductivity more than a century ago has significantly changed our world. The story began in 1911 when the Dutch physicist Heike Kamerlingh Onnes observed that the electrical ...

Physicists have discovered stacked pancakes of 'liquid' magnetism that may account for the strange electronic behavior of some layered helical magnets. Physicists have discovered "stacked pancakes of ...

Lodestone, a naturally-occurring iron oxide, was the first persistently magnetic material known to humans. The Han Chinese used it for divining boards 2,200 years ago; ancient Greeks puzzled over why ...
