Let’s learn about artificial intelligence
Computers are getting smarter all the time. At some tasks, they can even outsmart people.

Headphones or earmuffs could replace needles in some disease testing
A new system that uses earmuffs to collect gases coming out the skin could help doctors diagnose a variety of diseases, scientists say.
- Animals
Endangered or just rare? Statistics give meaning to the head counts
Whether studying tiny birds or massive whales, researchers collect a lot of data. The field of statistics helps them make sense of those data.
- Health & Medicine
What is the role of in-person classes in COVID-19’s spread?
New data haven’t shown that schools pose a big coronavirus risk to kids and their families, despite fears that they might.
- Climate
Warming cities may see more rain — and frequent flooding
Scientists are seeking to understand why and how to mop up excess precipitation.
- Climate
Stores and malls buy into ponds and rain gardens for flood control
An extra bonus: These rainy-day ponds clean up that dirty water running off parking lots.
- Chemistry
New glue offers to turn any small walking robot into Spider-Man
To climb walls, robot feet need to alternately stick and let go. A novel adhesive can do that. Its stickiness is controlled by electric fields.
- Chemistry
Lots of makeup may contain potentially harmful ‘forever chemicals’
Hints of PFAS compounds have turned up in about half of tested makeup products. Waterproof mascaras and lipsticks were very likely to contain them.
- Archaeology
How torchlight, lamps and fire illuminated Stone Age cave art
Experiments with stone lamps and torches are helping scientists see 12,500-year-old cave art with fresh eyes.
- Animals
Uncovering secrets of the glasswing butterfly’s see-through wings
The tricks of its transparency include sparse, spindly scales and a waxy coated membrane.
- Climate
‘Zombie’ wildfires can reemerge after wintering underground
Climate change may make these not-quite-dead blazes more common. Scientists are learning to predict where a zombie might emerge.
- Physics
Nuclear clocks are nearly here
More precise clocks could improve technologies such as GPS and help scientists test major ideas in science.
