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.

And maybe that's just part of the human psyche of wanting to go and explore places.

And maybe that extends back further than we would have thought.

He presented his case at a meeting of the

Society for American Archaeology in Washington, D.C., first reported on in an article by journalist

Andrew Lawler in the journal Science. The case goes like this. Hundreds of stone tools have now

been found, lodged in ancient soils on Mediterranean islands like Crete and Noxos.

We can't date the tools directly.

He compares it to car styles.

The tail fins of old Cadillacs, you know, you could syriate those and you could show, well, this is older than this or more
