Sound, as we know it, relies on a medium to propagate. Typically, it travels through particles in a medium, such as air or water, by causing them to vibrate. This fundamental principle has led to the common belief that sound cannot exist in the vacuum of space, where there is an absence of particles for sound waves to interact with.

Scientists from the University of Jyväskylä in Finland have successfully “tunneled” sound through a vacuum via an electromagnetic effect.

Researchers were able to transmit, or "tunnel," sound waves across small distances between two crystals in a vacuum.

Given the right circumstances, it is possible for sound to travel through a perfect vacuum.

A classic movie was once promoted with the punchline: ”In space, no one can hear you scream”. Physicists Zhuoran Geng and Ilari Maasilta from the Nano....

Scientists have devised a method to overcome distortion due to photon-polarization posed by the constant movement of satellites as well as scrambling of polarization in optical fibres and achieve secure long-distance communication without use of conv

This article explores optomechanical mass sensing, as opposed to conventional mass spectrometers, which classify analytes by measuring their mass-to-charge ratio.

Large numbers can only be factorized with a great deal of computational effort. Physicists at the University of Innsbruck, Austria, led by Wolfgang Lechner are now providing a blueprint for a new type of quantum computer to solve the factorization problem, which is a cornerstone of modern cryptography.
