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.

The Mariana Trench is the deepest spot in the world's oceans.

Only three humans have ventured into the trench in submersibles.

But plenty of our pollution has made the voyage to the bottom of the sea.

A new study finds that critters living more than six miles below the ocean surface

contain high levels of harmful compounds like polychlorinated bifenals or PCBs and flame retardants.

But an important thing is if you're at the deepest place in the world, there's nowhere else to go.

Alan Jameson, a marine ecologist at Newcastle University in the UK.

You can't be dispersed horizontally, you can't go back up.

So for every nanogram of pollutant that's gone into the deep sea,

there's no mechanism to put it back again.

So of course the values are going to be high,

because it's only a one-way traffic, right?

Jameson and his colleagues used robotic traps

to collect deep-sea amphipods living in the most remote parts of the

oceans. These creatures look a bit like shrimp, and they're well adapted to their extreme

environment, he says.
