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.

If you're a giant panda, this sound means romance.

I wouldn't call it a romantic serenade.

Megan Owen is a conservation biologist at the San Diego Zoo's Institute for Conservation Research.

There's nothing soft or demure about it.

And yet that's sound, called a bleat, that's B-L-E-A-T, just like a goat, signals that a

panda couple has hit it off, and copulation is nigh.

Owen and her colleagues analyze more than 2,500 panda sounds recorded during breeding introductions,

and they analyze the audio's acoustic qualities.

Their study in the Journal Royal Society Open Science is a sort of how-to guide for panda breeders,

cataloging the various vocal characteristics of a blind date. You've got an uninterested roar,

or a bark, a more ambiguous chirp, or an amorous bleat.

Decoding the sounds could be important not just for boosting panda numbers, Owen says,

but for avoiding very bad dates.

These are bears, and they have sharp teeth and claws, and they can do a lot of damage to one

another if they don't want to be around each other.

And these fine-tuned communication skills also make the case that the social lives of pandas
