While most of us have been content with swing and sliding doors for the vast majority of our needs around the home, the revolving door remains popular in a wide variety of contexts. It’s a confounding ...

Trying to untangle a knot in a mess of strings can be frustrating and time-consuming. But not so for molecular machines—molecules that convert chemical energy into mechanical work and motion. Machines ...

Integrating sensors into rotational mechanisms could make it possible for engineers to build smart hinges that know when a door has been opened, or gears inside a motor that tell a mechanic how fast ...

Accessibility in architecture is essential for creating built environments that accommodate of all ages, from young children to the elderly. In both public and private buildings—whether residences, ...
