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.

People speak thousands of languages in the world today, and same goes for the bird world.

Each bird species has effectively its own language.

Andy Radford, a professor of behavioral ecology at the University of Bristol.

And there might be similarities between some languages, just as there are in the human world,

and then there are other languages that sound extremely different,

even though they're conveying exactly the same meaning.

In fact, some birds are known to pick up on the language of other species.

In particular, they've learned to detect danger by eavesdropping on on the language of other species. In particular, they've learned to

detect danger by eavesdropping on the alarm calls of other birds. Radford and his colleagues

wanted to investigate how that learning occurs. So they first played an alarm call that Fairy Wrens,

an Australian bird, shouldn't be familiar with. A computer-generated alarm call, meant to mimic birds.

As expected, the unfamiliar sound had no effect on the fairy wrens.

But then the researchers paired the synthetic call with the chorus of alarm calls the wrens

would recognize.
