Researchers have demonstrated a solid-state approach to sound modulation that electronically creates the acoustic sensation of a moving sound source. A new speaker system developed at the University of Nottingham creates audio effects by manipulating sound waves around the listener rather than modifying only the electronic signal. The solid-state design recreates aspects of a classic […]

MIT Study Reveals Why a Neutrino Laser May Be Impossible
Physicists proposed a way to focus ghostly neutrinos into a laser-like beam, but new MIT calculations show that violent atomic recoil and the particles’ own quantum nature prevent the effect from taking hold. Trillions of subatomic particles stream through every square inch of Earth, passing through solid rock, massive stars, and human bodies every second […]
2 Billion-Year-Old Rocks Reveal How Life Helped Stabilize Earth’s Atmosphere
Ancient South African rocks reveal how phosphorus recycling may have helped Earth hold onto oxygen more than 2 billion years ago, sustaining conditions that allowed life to thrive. More than 2 billion years ago, oxygen began building up in Earth’s atmosphere, transforming a planet whose oceans and air had contained very little of the gas. […]
