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.

For a long time, archaeologists have dug for the shiny stuff, the sorts of artifacts that belong in museums.

They like pots. They like jewelry and gold and stuff like that.

Piers Mitchell, a biological anthropologist at the University of Cambridge.

Mitchell spends his time looking for something decidedly different

from such handmade relics. The thing he seeks? The preserved piece of human feces. Copperlites,

as they're called, are dried or mineralized pieces of poop. And Mitchell and his team found some

prime specimens in a trash heap at the ancient settlement of cattle Hoyek. That's in modern-day

Turkey and dates from 6,000 to Cattle Hoyick. That's in modern-day Turkey,

and dates from 6,000 to 7,000 BC. Mitchell's team ground up the poop samples with a mortar and

pestle, then dissolve them, and used microsives to filter out particles of various sizes.

The presence of certain molecules tipped them off that it was indeed human poop, and in two of

the samples, they found the intact

eggs of whipworm, an intestinal parasite that's far more likely to flourish in settlements than among

people who poop and then move along down the road to a new location. The discovery thus gives us a

glimpse of how human health may have changed as hunter-gatherers started to adopt a stationary

agricultural lifestyle.
