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.

What has one head, one foot, and one heck of an origin story. No, it's not a strange new superhero. It's a microscopic

worm called a rotifer that was brought back to life after spending about 25,000 years locked

in the Arctic permafrost. Its tale is told in the journal Current Biology. This is a long-term topic for our lab.

in Pushino, Russia.

He and his colleagues have spent decades probing the Siberian permafrost,

and they've managed to revive a variety of interesting organisms,

from a plant seed and simple bacteria to scores of more sophisticated single-celled critters.

We have isolated around 30 or maybe 40 strains already, or unicellular, you care.

But for some reason, people weren't totally wowed by resurrected amoebas.

Yeah, they don't respect now.

Rotifers are much, much better.

Rotifers are better, or at least more interesting, because they're multicellular animals,

with a head and a body, that can eat, crawl around, and make more rotifers.

And considering they're more or less teeny-tiny worms,

they're actually cute little guys.

They don't have guys.
