Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.
- Tech
New thermal ‘cloak’ keeps spaces from getting too hot or too cold
A prototype fabric could help keep cars, buildings and other spaces cooler during heat waves while also reducing greenhouse-gas emissions.
- Materials Science
This house is partly made of recycled diapers
After being washed, dried, sanitized and shredded, used diapers were mixed with other materials to make a strong concrete.
- Materials Science
Analyze This: A new fabric mimics polar bears’ pelts for warmth
With layers that work like polar bears’ skin and fur, a material absorbs light and keeps it from escaping.
- Tech
Nanocrystal ‘painted’ films may someday help relieve summer heat
The rainbow palette and cooling powers of new plant-based films comes from their microscopic surface patterns of tiny crystals.
- Tech
A new solar-powered gel purifies water in a flash
The unusual, fruit-inspired structure of this material provides quick filtration that could satisfy people's daily water needs.
- Chemistry
Chemists have unlocked the secrets of long-lasting Roman concrete
By searching ancient texts and ruins, scientists found a concrete recipe that could make buildings stronger — and help address climate change.
- Animals
Let’s learn about frogs
Frogs are a fascinating bunch of amphibians. Unfortunately, they’re also dying off in huge numbers.
- Tech
Think of this new tech as sunglasses for our windows
Keeping buildings cool can use a lot of energy. Thanks to quantum computing, engineers designed a coating to cut the warming light that enters windows.
- Climate
Creating less new stuff could greatly help Earth’s climate
Instead of throwing unneeded things away, scientists recommend moving to a cycle of reducing, reusing, repairing and remaking old things into new ones.
- Materials Science
Let’s learn about piezoelectric materials
Piezoelectric materials turn mechanical energy into electrical energy — and vice versa.
- Materials Science
Scientists Say: Hydrogel
Tangled polymer chains help hydrogels hold their shape despite being full of water.
- Environment
For a better brick, just add poop
Sewage sludge. Cow dung. They’re not just waste — scientists are finding uses for processed poop in construction materials.
