In everyday life, designing spaces that both let air flow and absorb sound can be a tricky balancing act. Usually, materials that allow air to pass through—like vents—also let sound escape, making it ...

A new University of Mississippi study shows that some sound waves don't just move forward—they also move slightly to the side. Understanding this movement could help researchers develop more precise ...

“This project started with a simple question: why do basketball shoes squeak?” Adel Djellouli, a study co-author and materials scientist at Harvard’s School of Engineering and Applied Sciences (SEAS), ...

Basketball shoes on a gym floor, bicycle brakes in need of a tune-up, or the squeal of tires are everyday examples of squeaking sounds. Such sounds have long been attributed to stick-slip friction, or ...

Although few people ever get the chance to travel at the speed of sound, it is an alluring flight goal and an impressive technological feat. Though average people have flown at high speeds on ...

Neutrino physics remains a pivotal area in the quest to unravel fundamental aspects of particle behaviour and the evolution of the universe. Neutrinos—elusive, nearly massless particles—are known to ...
