Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years.

Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

This is Scientific American's 60-second science. I'm Christopher in Taliatta.

In the movie Armageddon, an asteroid the size of Texas is hurtling towards the earth.

All seems lost, but then Bruce Willis sacrifices his own life to detonate a thermonuclear

bomb on the asteroid.

And then you hear this from mission control.

The two halves are going to miss us by 400 miles, and most of the small particles have been

vaporized.

Breaking a rock that big into two halves that somehow miraculously dodge the earth,

it's a bit of Hollywood magic.

But scientists are studying what

would really happen in such a scenario. A big part of what we do is basically looking at how

things break, smashing things together, and what happens after that. Charles Almere is a mechanical

engineer who studies planetary science at Johns Hopkins University. He and his colleagues modeled what

might happen if you smashed up

a 15-mile-wide asteroid made of basalt. They started by assuming the asteroid has some tiny cracks

already running through it, based on studies of real rock. And then they struck the hypothetical

space rock with another smaller rock, just a mile wide, screaming towards the asteroid at more than 11,000
