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.

Okay. Climate researcher Luciana Gatti stares grimly out of an oval porthole.

I'm sitting next to her in a single-engine prop plane.

We climb into the sky above the eastern Amazon in Brazil. She motions toward the ground below us. You see, you see, the forestation here. Oh, right there, right there. Yeah.

Luciana works at Brazil's National Institute for Space Research. She started coming here two decades ago. She says that back

then, the land we're looking down on, was completely blanketed in green. The crowns of millions of

trees intertwined. The few subsistence farms that interrupted this green ocean only seemed to prove

how vast the jungle was.

Today all we see through the plains window glass are brown and green jigsaw puzzle pieces

alternating between newly cleared jungle, grain crops and the remains of recent harvests.

They are killing the forest to transform everything in soybean.

I'm Daniel Grossman, reporting for science quickly.

I've come to the Amazon to find out what Luciana is learning about the health of the forest

in its role influencing the rate of climate change.

And the plane we're on isn't just used for taking in the view.

It's part of Luciana's science.

She hires this plane and others to collect air above the changing forest,

because mixed in with the air is a key to climate change, carbon dioxide.
