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.

Studying birds for a living might sound like a cool job, but it's not without its logistical

challenges for us land-bound animals. I had a northern genet, so a really large bird breathing

on the top of a cliff.

David Gremier, a seabird ecologist at the French National Center for Scientific Research.

And from the bottom of the cliff, I couldn't see what was happening in that nest.

I couldn't even see whether the bird was home or not.

Gremier says technology offers a simple solution.

A drone carefully flown at a high altitude over the colony would have been really helpful.

That's right, a drone.

Grumier says scientists and citizens alike are increasingly using drones to approach birds,

either for fun or legitimate research.

But they're taking flight without knowing how

the aerial robots might affect their avian study subjects.

So Grumier and his colleagues hit the zoo, employing a professional drone pilot to fly test

runs near Mallard Ducks with a 14-inch diameter quadcopter.

They then got permission to repeat the experiment on wild flamingos
