We look into the engineering reasons why the Francis Scott Key bridge collapsed after a ship crashed into it. Also, a new analysis finds that more viruses spread from humans to animals than from animals to humans.

It wasn’t that long ago that scientists didn’t think animals could rival humans in terms of intelligence, emotions, or empathy. But the groundbreaking work of Dr. Frans de Waal helped change all of that. De Waal spent his life studying the lives of animals — especially our closest cousins, chimpanzees and bonobos.

Ever since we learned that an asteroid slammed into Earth, wiped out the dinosaurs, and changed the course of life on this planet, scientists have wondered if it could happen again. It turns out there is an asteroid, called Bennu, that has a very small chance of colliding with our planet in the year 2182. But beyond that, Bennu could hold informati…

The next time you go to the zoo, take a few minutes by the sea lion habitat to watch the way they swim. While most high-performance swimmers use powerful kicks from hind appendages to power through the water, sea lions instead use their front flippers, moving with a pulling motion.

It’s the idea that those animals look very much the same way their species may have looked millions of years ago, with limited evolutionary change over that time.
