Revolutionary Device Enables One-Way Sound Transmission

Researchers at ETH Zurich have developed a groundbreaking device that enables sound waves to travel in a singular direction, enhancing communication technologies. This innovative disk-shaped cavity uses swirling air to manipulate sound waves, allowing for non-reciprocal transmission, which can improve noise suppression and sound isolation. With potential applications in telecommunications and audio engineering, this advancement could revolutionize how we interact with sound.

MIT Scientists Image Movement of Heat in Superfluid Quantum Gas for the First Time

MIT scientists have made a groundbreaking discovery in the world of superfluid quantum gas by successfully imaging the movement of heat in a wave, known as ‘second sound,’ through this exotic fluid for the first time ever. This achievement holds significant implications for the understanding of high-temperature superconductors and neutron stars, and opens up new avenues for research in materials science and astrophysics.
