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.

Chimpanzees can make tools, they display emotions, and they can outfox humans at certain memory games.

But chimps also resemble us in another way. They use medicine. They're known to eat tough leaves and bitter plants to purge parasites from their guts.

Now researchers have observed chimps applying a never-before-seen type of treatment.

They snatch up flying insects and apply them to their wounds.

You can see this happening in a video they filmed at Luongo National Park in Central Africa.

Susie is sitting up and then she's catching something from underneath a bush. She's putting it between her lips. She seems to press it. And then she's grabbing the foot of her son

with wood and then she is applying the insect onto that wound.

Simone Pika is a cognitive biologist at the University of Osneberg in Germany, part of the team that studies

these chimps. She says it's possible that insects have antibacterial or soothing qualities,

but this could also be a cultural practice with no medical benefit at all.

Maybe an individual just found out that it's intriguing, then I get a lot of intention,

others come, maybe then I get some grooming. And so it just

resulted into a social behavior. After all, Pika points out that humans perform plenty of rituals

with no obvious function. Her team reported their findings in the journal Current Biology.

And they write that this could be an example of what's called pro-social behavior.

They help each other, and it's not just the mother helping her offspring, and it's not somebody
