Negative pressure governs not only the Universe or the quantum vacuum. This phenomenon, although of a different nature, appears also in liquid crystals confined in nanopores. At the Institute of ...

Negative pressure is a rare and challenging-to-detect phenomenon in physics. Using liquid-filled optical fibers and sound waves, researchers have now discovered a new method to measure it. In ...

The Romantic poet John Keats once defined a state of mind wherein a person "is capable of being in uncertainties, mysteries, doubts, without any irritable reaching after fact and reason." He called it ...
