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.

In the jungle, home is anywhere you can raise your babies, while trying not to get gobbled up by somebody else.

Take a tiny creature from Brazil, whose name is longer than it is.

The Bahia's broad-snout, cascaded tree frog. It likes to hang out in the little ponds that form in cavities within bromeliad plants. These tiny pools are technically known as

phytotelmata, from the Greek words for plant and pond. A male finds a bromeliad and attracts a female who lays her eggs directly into the water.

The male stays behind to guard the eggs and the tadpoles, spending the rest of his life within that one

plant. But not just any bromeliad pool will do. It's so crazy that there are some really nice big bromeliads and I never found our frog there.

If I would be the frog, I would like that bromeli.

Herpetologist Mirko Soley from Brazil's State University of Santa Cruz,

quoting his graduate student, Amanda Lantor Silva.

But then we made that research and we saw that there were trade-offs.

In all, Solay and his team surveyed 239 bromeliads within a protected part of Brazil's Atlantic rainforest,

of which 74 were occupied by frogs.

The frogs preferred big bromeliads, but the very largest bromeliads were unoccupied by the frogs,

which suggests there's a Goldilocks situation.

And the researchers think it has to do with the size of the frog's alligator-shaped heads.
