Exhaust systems have changed dramatically over the years, from the simple single-muffler systems from cars of the '50s and '60s, to the active exhaust systems from select late model cars like the 2025 ...

Researchers have developed a novel type of nanomechanical resonator that combines two important features: high mechanical quality and piezoelectricity. This development could open doors to new ...

Researchers have built a tiny butterfly-shaped optical resonator to improve the sensitivity of ultrafast measurements of electron beam pulses. They found that the enhancement allows less intense ...

In either the 1850s or 1860s, German physicist Hermann von Helmholz created a device to analyze sound. In 2005, that same sort of device made its way into the airbox of the new 3.8-liter flat-six of ...
