Exotic states of matter known as time crystals are largely considered a quantum phenomenon. Now, a team from New York ...

Acoustic streaming generated by airborne ultrasonic phased arrays plays a critical role in the performance of advanced ultrasonic technologies, including midair haptic feedback, odor delivery, and ...

A strange form of matter called a time crystal has fascinated physicists for about a decade. These systems move in repeating cycles, even without a steady external push.

NYU physics researchers have observed a new type of time crystal—one whose particles levitate on a cushion of sound while interacting with each other by exchanging sound waves. Above, a bead (purple) ...

From a toe-tapping disco classic to a pair of Mafia movies that cemented themselves in popular culture, these films from the 1970s are endlessly rewatchable.

Soil is one of our most precious resources. Ecoacoustics, or the study of environmental sounds, has been around for a century, but it has only recently been applied to understanding soils. This ...

Helium is famous for making balloons float, voices squeak, and as a critical resource for MRI machines and aerospace engineering. Helium is expensive and scarce, finding leaks quickly is essential, ...

Time crystals, a collection of particles that "tick"—or move back and forth in repeating cycles—were first theorized and then ...

A team of researchers from the Ministry of Health in Kuwait has successfully demonstrated the destruction of SARS-CoV-2 virus ...

Gayle Anderson learns about Sonic Fire Tech, a startup company founded by former NASA engineers, that uses a patented technology to extinguish wildfires using sound waves. Company officials claim the ...

Sound machines promise better sleep, but new research suggests they may quietly steal your REM and deep sleep.
