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 Steve Merski. Got a minute?

So I just don't approach at least initially a group of muscoxen.

Joel Berger with the Wildlife Conservation Society and Colorado State University.

What I do is to take into account other factors that might reflect their responses. And so what I need to know

is something about the group size, whether or not males are in the group. I need to know something about

snow depth, about snow penetration, or how hard the snow is. And then I'll approach and try to understand

whether they stay, whether they flee, whether they charge.

Oh, one more important point.

When Berger approaches the musk oxen on Russia's Wrangell Island north of the Arctic Circle,

he's dressed up like a polar bear.

I know the media has a good time when we dress up as animal models.

Of course they do.

But remember, two noble laureates,

Conrad Lorenz and Nico Tinberg, and led the way for getting inside the minds of animals,

and they've done this through innovative models. Polar bears prefer seals for their meals,

but the loss of sea ice is forcing them onto the land to hunt for prey that's usually

not on their menu. The idea here is to gauge the response of muscoxen to this formerly rare threat.
