Speed, or “rate,” of sound changes can make it difficult to understand speech in challenging situations, such as in noisy environments.

The message is that for protective health benefits people could not only ideally aim for 10,000 steps a day but also aim to walk faster.

The maximum speed of signal transmission in microchips is one petaherz or about 100,000 times faster than current transistors.

One big issue in physics education is to generate student enthusiasm for the course material. These dinosaur problems really spark interest.

The sub is two knots faster than the top cruising speed of a bottlenose dolphin, and five knots faster than the average submersible.

A University of Texas at San Antonio researcher is part of a collaboration that has set a world record for innovation in quantum computing.
