Duchenne muscular dystrophy is the most common type of muscular dystrophy, affecting more than 10,000 males at birth per year in the United States with severe physical disability, chronic wasting and ...

An optomechanical accelerometer that uses light to measure acceleration. Credit: F Zhou/NIST An accelerometer that uses laser light instead of just mechanical strain can register changes as small as ...

This simple dynamic response enabled the scientists to achieve low measurement uncertainty over a wide range of acceleration frequencies -- 1 kilohertz to 20 kilohertz -- without ever having to ...
