Voltage fluctuations, light fluctuations, temperature fluctuations—any fluctuations are troublesome and thus undesirable. They don't just cause discomfort; in engineering and medical applications, they affect the accuracy of measurements or introduce errors in controls. Even at the minute level of quantum phenomena, fluctuations are considered undesirable.

This bird flies thousands of miles, but its wings have a catch

Scientists have uncovered an unexpected trade-off in the wings of the European nightjar, a bird that migrates thousands of kilometers but sacrifices high-speed flight efficiency to hunt insects with remarkable agility. Even more surprisingly, it generates thrust on the upward win

A quantum highway just one atom high could transform superconductors

Scientists discovered that atomic steps just one atom high can guide quantum vortices through superconductors, making them move more than 1,000 times more easily in one direction than another. This remarkable control over quantum motion could lead to a new generation of ultra-eff
