The last time we took a break from any scientific considerations and blatantly entertained our minds with something equally crazy and inventive, there was just one easy option. Of course, it was ...

The researchers conducted an experiment in which they were able to manipulate the speed of sound. They enriched the air composition with helium to increase the speed of sound, and under these ...

Ryan Duncan froze. He had just performed a new experiment examining common graphite—the stuff of pencil lead—but the results seemed physically impossible: Heat, which typically disperses slowly, had ...

Using a microphone, a laser, and some crafty mathematics, a team of scientists has measured the speed of sound on Mars, in what is a scientific first and another cool finding made possible by NASA’s ...

Karen Hopkin: Bats rely on echolocation to navigate the night skies and to chase down and capture even erratically moving prey. But even more impressive than their aerial acrobatics are the mental ...

Hypersonic flight could one day make long-haul travel as quick as a short movie. Researchers are testing how turbulence behaves at extreme speeds, a critical hurdle for designing these aircraft. Their ...

New research shows that the speed of sound on Mars varies considerably by location and temperature. The findings could help scientists understand sounds picked up by Martian rovers, as well as make ...

Nuclear physicists proposed a method to measure the speed of sound characterizing matter created in nuclear collisions. Heavy nuclei consist of hundreds of protons and neutrons (belonging to a group ...
