We are surrounded by waves. tiny vibrational waves transport sound to our ears. Light waves stimulate the retinas of our eyes. Electromagnetic waves bring radio, television and endless streaming ...
Yushun Zeng squishes cancer cells in a petri dish at work. No, not with his ungainly, macroscopic human fingers. Zeng, an engineering graduate student at the University of Southern California, has ...
This article was originally published on The Conversation. Read the original article. We know that there is sound on planets and moons in the solar system—places where there's a medium through which ...
Look at that mountain! Imagine you are standing at the base of a volcano looking up. You were told that the volcano isn’t going to erupt anytime soon, but you notice a little bit of smoke (or is that ...
The power of sound reaches far beyond your ears. While you're used to hearing sound through music, voices, or noise, your body is also quietly listening—at the cellular level. Recent research shows ...
Researchers have found a way to make materials that are normally opaque to sound waves completely transparent. Their system involves placing acoustic relays at strategic locations so that sound waves ...
Researchers have constructed a 'meta-mirror' device capable of perfectly reflecting sound waves in any direction. The proof-of-principle demonstration is analogous to looking directly into a mirror ...
The earliest scientists first observed the waves that earthquakes produce before they could accurately describe the nature of earthquakes or their fundamental causes, as discussed in Lessons 1–5.
