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 American's 60-second science. I'm Christopher in Taliatta.

Antarctica is known for its great expanses of white, and not just snow.

If it's fresh, it can either be still white or pinkish, and eventually it all turns brown, muddy brown.

Steph Bocorst is an ecologist at Vria University in Amsterdam, and the initially white stuff

he is talking about is penguin poop. The first thing you notice of it is the smell. Basically,

you're squishing through puddles. Of what you first think is mud, but it's actually just

poo. And that produces that really strong ammonia smell, which you can really smell from

miles away. But it's not just the smell that travels on the wind.

Amonia contains nitrogen, a valuable fertilizer,

so the winds carry nourishment to nearby mosses and lichens.

And that in turn supports teeming communities of the largest fully terrestrial animals in Antarctica,

invertebrates, like springtails and mites.

Bochors and his colleagues took air and plant samples around the poop piles and found this airborne ammonia fertilizer

enriches life as far as a mile away. The full details are in the journal Current Biology.

And the work makes it easier for scientists like Bocorce to remotely estimate Antarctica's biodiversity.

You don't have to go to all these different field sites.

We can actually basically sit at home, take these pictures with satellites, and then get an idea where the highest biodiversity should be along the peninsula.
