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.

Yachtold 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 Fiona Samuels.

The Red Wolf once roamed a huge swath of the eastern United States. The historic range of these rust-colored canines stretched from Long Island, across to Missouri and down to the Texas-Mexico border.

But by 1972, the population was reduced to only roaming a small area along the Gulf

coast due to habitat loss and hunting. To conserve the species, 14 individuals were captured

as part of a breeding program. In 1980, their wild relatives were

declared extinct. The captured wolves were all that was left. The species has gone through this

huge bottleneck, and through that, lost a lot of genetic variation, and now there's a fair

amount of inbreeding in the species, because you can't help it when you have so few founders.

That's Kristen Breske, an assistant professor at Michigan Technological University the inbreeding in the species because you can't help it when you have so few founders.

That's Kristen Breske, an assistant professor at Michigan Technological University whose research focuses on the conservation of genetics of wild animal populations.

I think what captures the imagination with the Red Wolf and I think this work is it's been

the underdog.

It's been the underdog scientifically.

It's been the underdog for conservation. been the underdog scientifically. It's been the underdog for conservation.

It was, you know, all wolves were heavily persecuted.

But the red wolves were heavily persecuted to the point that only 14 were left.

Now, Breski and her collaborators have found a surprising new pool of red wolf genes
