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.

This is Scientific Americans' 60-second science.

I'm Karen Hopkins. This will just take a minute. Everybody loves chimps, especially their endearing entreaties.

Scientists too love to listen to chimps chat.

And they enjoy sharing these colorful commentaries with their colleagues. Now, anyone with a hankering for primate prattle can listen in, because researchers from the

Netherlands have made available online a digitized catalog of more than 10 hours' worth of chimpanzee calls.

The recordings are described in a new journal, published by nature, called Scientific Data.

The audio, which includes more than a thousand separate data files, was captured in the early

1970s by the late Hetty Fanta Rite ploy.

She recorded the various screams, barks, and who calls made by a group of chimps,

including 17 youngsters living in the wild in the Gombe National Park in Tanzania. Fonda Wright-Ploy and her

husband Franz Ploy were planning to study how chimp vocalizations change over the life of an individual,

but they ended up focusing on how baby chimps behave, so their extensive recordings have remained

largely unexplored. One thing that pops out of this collection is that immature chimps

grunt more than their adult counterparts, which suggests that you might not want to talk

to baby Bonzo before he's had his morning banana smoothie. Thanks for the minute. For Scientific

American's 60 Second Science, I'm Karen Hopkins.
