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. To learn more about Yachtold, visit yawcult.co.

That's Y-A-K-U-L-T-C-O-J-P. When it comes to a guide for your gut, count on Yacult.

This is Scientific American 60-second Science. I'm Suzanne Bard.

Some scientists stick to the lab, but others brave venomous snakes and down power lines.

Take Jonathan Pruitt, an evolutionary biologist at McMaster University. During last year's

hurricane season, he went to the U.S. Southeast to see how extreme weather affects spiders.

The goal of this experiment was basically to figure out how rare but extreme events might sculpt the traits of animals that we see out there in the wild.

The inherent difficulties in doing this kind of work has meant little research into how disasters

can be a driving force behind natural selection.

The only way that I was able to do this was via the assistance of locals who immediately

following these storms all get into their trucks and drive around to survey the damage

of their houses, but they also bring chainsawls.

And so they will be cutting their way

through state roads. And I basically just draft right behind what could be a conga line of F-150s

with chainsaws and use them to cut a path back to my study sites. All that to survey the habits of

Tangleweb spiders, which live in colonies above bodies of water.

And they cooperate into doing prey together like a tiny spidery pride of lions.

The spiders come in two personality types, docile and aggressive.

Aggressive colonies are prone to cannibalism, fight among themselves,
