When football helmets collide, they produce an unmistakable sound. With concerns rising over concussion risks, some parents and others are increasingly concerned about each pop they hear.
Researchers at The Ohio State University have discovered how to control heat with a magnetic field.
A system for using sound waves to spot potentially dangerous cracks in pipes, aircraft engines and nuclear power plants has been developed by a University of Strathclyde academic.
The performance of mobile phone cameras and solar cells could be boosted by "nano-earthquakes", researchers have found.
The ability to control the intrinsic angular momentum of individual electrons – their "spins" – could lead to a world of new technologies that involve storing and processing information.
For once, slower is better in a new piece of technology.
Acoustic-gravity waves—a special type of sound wave that can cut through the deep ocean at the speed of sound—can be generated by underwater earthquakes, explosions, and landslides, as well as by surface waves and meteorites. ...
NIST scientists have developed a novel method to rapidly and accurately calibrate gas flow meters, such as those used to measure natural gas flowing in pipelines, by applying a fundamental physical principle: When a sound ...
For drones to make it to the big time, they will need to learn to get around in towns and cities—without falling on car hoods or crashing into pedestrians.
