Let’s learn about cellulose
The world’s most abundant natural polymer is finding all kinds of new uses, in everything from ice cream to construction.
- Space
Explainer: All about orbits
A handful of rules can describe the route some object repeatedly takes around another in space. Calculating that path, however, can be quite complex.
- Materials Science
This new fabric can ‘hear’ sounds or broadcast them
With special fibers that convert tiny vibrations to voltages, a new fabric senses sound. Someday, such fabrics could monitor the body or aid hearing.
