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.

Some birds produce beautiful songs.

Woodpeckers are not among them.

The most familiar sound they make is when they tap on tree trunks with their bills to produce what's called drumming.

The drumming that they show is essentially them kind of slamming their head against a tree

at a remarkable speed.

Wake Forest University biologist Matthew Fuchsiger.

Some of the woodpeckers will use this kind of drumming-type maneuvering to excavate a nest.

They'll make little caches in a tree to store food, or some of

them will actually forage that way. But then they also use it for the social signal.

Fuchsager's team broadcast the pre-recorded sounds of head slams to mated pairs of downy

woodpeckers in the woods nearby. They discovered that there's a lot of information communicated in the drumming. For example, woodpeckers in the woods nearby. They discovered that there's a lot of information

communicated in the drumming. For example, woodpeckers that produce shorter drums are probably

kind of wimpy and easy to beat in a fight. But if a drum is longer, the challenger might be

advertising itself as a stronger, tougher bird, one that's a bit harder to fend off.
