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.

There's a well-known conspiracy of ravens.

That's what you call a group of ravens,

that likes to hang out near a zoo in the Austrian Alps.

Every day, these ravens conspire to steal the food that's set out for the wild boars there.

So we had a really great opportunity to really watch those individuals daily.

University of Vienna, cognitive biologist Marcus Bukle.

He spends lots of time ignoring the zoo animals and watching the ravens.

What we found is that every time they come, they do those food calls, which are very typical

for the ravens, then they are close to potentially dangerous food resources.

The ravens use these calls to recruit their buddies to show up, both to reduce potential dangers from predators,

and to overpower dominant ravens who might be trying to hoard all the food for themselves.

But Bukle and his colleagues began to suspect the calls revealed other information.

So we had the feeling we could say this is a true one-in-eye, this is the sub-ed-out,

and this is most probably an adult, just by listening to the calls.

If the researchers could use the calls to distinguish among ravens,

then perhaps the ravens themselves could do so too.
