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 Talata. Got a minute?

It's a scenario straight out of Hollywood. You're up in a spacecraft.

You've got this capsule around you.

And a loose bolt. A piece of space junk is zooming your way.

And it's going really fast. It's going to very likely

actually pass through your spacecraft and leave both entry and exit holes.

So all of a sudden now your atmosphere is rushing out those holes and you want them sealed right away.

That's Timothy Scott, a polymer scientist at the University of Michigan, Ann Arbor.

He and his team have devised a potential solution to this space disaster,

a material that patches itself up

less than a second after impact. Think of an ice cream sandwich. The central part, the ice

cream of our sandwich, is a liquid resin. The cookie parts are sheets of thermoplastic. When a

projectile or a piece of space junk punctures the sandwich, it exposes the liquid

part to the ship's oxygen, which causes it to solidify, patching the hole. The researchers tested

sheets of the self-healing material at a firing range, filming the results with high-speed video.
