HS-ETS1-1
Analyze a major global challenge to specify qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants.
- Earth
A new clock shows how gravity warps time — even over tiny distances
This clock measured how gravity changes the passage of time in different places — even spots just one millimeter apart.
- Agriculture
Here’s why cricket farmers may want to go green — literally
Crickets are great sources of protein, but they often kill each other in captivity. Green light could help solve the problem, two teens find.
- Humans
Teen-designed tech could expand access for people with disabilities
Several inventors at the 2022 Regeneron ISEF competition offered creative solutions that translate sign language and help blind people navigate.
- Chemistry
Reusable plastic bottles release hundreds of pollutants into water
Data show the plastic ends up tainting drinking water. For now, scientists don’t know what health risks downing these pollutants might pose.
- Environment
Bubbles could help remove trash from rivers
One young engineer devised a way to make bubbles sweep away the trash floating down a creek, like the one in her backyard.
- 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.
- 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.
- Life
Kitchen sponges are bacteria’s dream home
Sponges are favorite spots for bacteria, partly because of the mixed-housing environment that the cleaner-uppers offer microbes.
- Chemistry
We all unknowingly eat plastic, which may host toxic pollutants
In the environment, plastics attract all types of toxic chemicals. If ingested, new data show, chemicals on those plastic bits may harm the gut.
- 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.
- Tech
A new device uses atoms’ quantum weirdness to peer underground
Quantum sensors like this one could monitor magma beneath volcanoes or uncover archaeological artifacts.
- 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.
