- Animals
Feral cats appear to be pathetic at controlling New York City’s rats
When cats are on the prowl, rats may become harder to see, but roaming cats actually killed only a few.
- Life
In China, a deadly strain of bird flu now easily infects ducks
H7N9 evolved the ability to infect ducks just as a vaccine for chickens came into use.
- Neuroscience
Survey raises worries about how screen time affects kids’ brains
A large study of U.S. children ties lots of screen time to lower thinking skills, but the relationship between the two is still unclear.
