Analyze a major global challenge to specify qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants.
- Brain
Patterns in brain activity can identify who will struggle to read
Certain patterns of brain activity predict whether teens are strong readers or will struggle. Those diagnostic patterns show up even when doing math.
- Materials Science
Bandages made from crab shells speed healing
The chitin in seafood wastes, insect “bones” and fungi is a chemist’s dream. Used in a new medical dressing, it beats regular gauze for wound healing.
- Animals
Science and Indigenous history team up to help spirit bears
When scientists and Indigenous people work together, their efforts can benefit bears and people.
- Plants
Scientists may have finally found how catnip repels insects
The plant deters mosquitoes and fruit flies by triggering a chemical receptor that, in some animals, senses pain and itch.
- Tech
5G promises new energy savings for digital tech
A new way to transmit wireless communications promises time and energy savings by using networks of smaller cells.
- Tech
Greening your digital life
The less electricity you use while playing video games or using your devices, the less impact you’ll have on climate change.
- Psychology
Boredom may pose a public health threat in the social distancing era
Boredom contributes to pandemic fatigue, and it may account for why some people don’t follow social distancing rules.
- Science & Society
Machine learning includes deep learning and neural nets
By combining patterns found in mountains of data with information gleaned from mistakes, these computer programs expand their artificial intelligence.
- Health & Medicine
Some young adults will volunteer to get COVID-19 for science
Researchers will soon give some healthy people the new coronavirus. Their young volunteers have agreed to get sick to speed coronavirus research.
- Tech
A robot made with a Venus flytrap can grab fragile objects
Scientists have “borrowed” the hair-trigger leaves of Venus flytraps to make a gentle grabber that can be controlled by a cellphone app.
- Science & Society
New technology can get inside your head. Are you ready?
New technologies aim to listen to — and maybe even change — your brain activity. But just because scientists can do this, should they?
- Animals
Newfound technique allows some tree snakes to climb wide trees
When a tree is too wide to climb, brown tree snakes use a lasso-like trick to slowly ascend up to snacks.
