A certain phenomenon has confounded scientists for almost two centuries: lone waves, strangely tall and fast, moving independently of the ebb and flow around them.

In physics, the Fermi-Pasta-Ulam-Tsingou (FPUT) problem—which found that certain nonlinear systems do not disperse their energy, but rather return to their initial excited states—has been a challenge that scientists have ...

Solitary waves called solitons are one of nature's great curiosities: Unlike other waves, these lone wolf waves keep their energy and shape as they travel, instead of dissipating or dispersing as most other waves do.

(Phys.org)—Neurons might not be able to send signals as fast as electrons in wires or photons in fiber, but what if they can communicate using miniature sonic booms? That would be quite a revolutionary discovery. A group ...
(Phys.org) —Defining the essential character of the action potential of neurons has proven to be an elusive task. As typically happens, the biggest advances seem to have been made early on. In this case it was Hodgkin and ...
(Phys.org) —Scientists have developed an acoustic lens that produces pressure pulses that are so intense they're called "sound bullets." Although they are too high-pitched to be audible to the human ear, the sound bullets ...
Their effect on the surface of the ocean is negligible, producing a rise of just inches that is virtually imperceptible on a turbulent sea. But internal waves, which are hidden entirely within the ocean, can tower hundreds ...

Tiny pulses of light one billionth of a second apart, travelling further than from the Earth to Sun, were used in an exquisitely sensitive experiment at The University of Auckland to explore fundamental interactions between ...

Sound waves are commonly used in applications ranging from ultrasound imaging to hyperthermia therapy, in which high temperatures are induced, for example, in tumors to destroy them. In 2010, researchers at Caltech led by ...
