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.
- 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.

Analyze This: Corals stash microplastics in their skeletons
Scientists have wondered where the ocean’s microplastic pollution ends up. Corals may trap about 1 percent of particles in tropical waters each year.
- Chemistry
New cloth cools you when you’re hot, warms you when you’re cold
Scientists 3-D printed the new fabric, which has even more tricks up its sleeve — such as conducting electricity and resisting radio waves.
- Materials Science
Engineers borrow a tree’s cellulose to toughen new materials
Cellulose gives plants their strength. Engineers are turning this renewable, environmentally friendly resource into brand new materials.
- Chemistry
A disinfectant made from sawdust knocks out deadly microbes
It’s made by pressure-cooking sawdust and water, is cheap and easy to make — and could lead to greener cleaning products than chemicals used today.
- Archaeology
The earliest known pants are surprisingly modern — and comfy
This 3,000-year-old garment was not only stylish but also functional. By recreating it, scientists also unraveled its complex and multicultural origins.

Scientists Say: Cellulose
Cellulose is an abundant natural polymer found in plants and algae. It’s used to make everything from paper to clothing.
- Earth
Widely used pesticides may threaten Earth’s ozone layer
Data show a major class of long-used “eco-friendly” copper chemicals unexpectedly react with soil, making gases harmful to Earth’s protective ozone layer.
