Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.
- Tech
‘Frozen smoke’ could protect electronics from annoying static
A fluffy material made from cellulose nanofibers and silver nanowires can protect electronic devices by blocking more than 99.99 percent of disrupting interference, a new study reveals.
- Environment
Washing your jeans too much might pose risks to the environment
Jeans shed thousands of denim fibers in every wash. Those fibers, and the chemicals used to treat them, now are showing up in even the Arctic Ocean.
- Humans
Changing climates can take cooling tips from warm regions
When summer heat waves hit northern cities, people might look to keep cool using tropical building strategies — and forgotten architectural wisdom.

How to recycle ‘nonrecyclable’ plastics
A new process can convert some nonrecyclable plastics into a type that now can be reused. That could greatly cut down on wastes sent to landfills.
- Chemistry
New solution for carbon dioxide: Turn it into ‘green’ fuel
Chemists have created a new way to convert carbon dioxide into ethanol. It might one day help remove excess CO2 — a greenhouse gas — from the air.
- Materials Science
Will bacterial ‘wires’ one day power your phone?
An accidental discovery helps scientists generate electricity out of thin —but humid — air with bacteria-made protein nanowires.
- Physics
Shape-shifting cuts give shoes a better grip
With pop-out structures inspired by kirigami and animals, a shoe sole goes from flat to spiky to boost friction on slippery surfaces such as ice.
- Physics
A contrast between shadows and light can now generate electricity
A new device exploits the contrast between bright spots and shade to produce a current that can power small electronics.
- Plants
Silk-based microneedles may help treat diseased plants
Engineers have invented silk microneedles to inject medicines into plants. One day farmers might use drones to dart their sick plants with meds from the air.
- Space
Astronauts may be able to make cement with their own pee
Lunar dust and a compound found in urine might one day be used to build future dwellings on the moon, a new study finds.
- Chemistry
Ancient recipes helped scientists resurrect a long-lost blue hue
Led by medieval texts, scientists hunted down a plant and used its fruit to make a blue watercolor with mysterious origins.
- Physics
Science offers recipes for homemade coronavirus masks
New studies provide data on what types of mask materials protect best against the virus that causes COVID-19. They also point to the value of a really snug fit.
