‘Mass Extinction’ vivifies the science of die-offs
The dinosaurs were killed off some 65 million years ago after a colossal asteroid struck Earth. But what many people probably don’t know is how paleontologists came to that conclusion. "Mass Extinction: Life at the Brink" tells that story.
- Animals
Scientists’ tags on fish may be leading seals to lunch
In an experiment, 10 young grey seals learned to associate the sound of a pinging tag with fish. The tags may make fish vulnerable to predators, scientists say.
