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.

Polar bears spend most of their time roaming the sea ice in search of seals.

And seals spend most of their time underneath that ice, avoiding the top predator.

But climate change is giving polar bears additional challenges in their searches for food.

Sea ice is now drifting faster.

George Durner is a research zoologist

with the United States Geological Survey

Polar Bear Research Program.

He and colleagues compared sea ice conditions

from 1987 to 1998

with those from 1999 to 2013.

And what we found was that ice drift at the locations used by polar bears increased 30% in the Beaufort Sea and 37% in the Chukchi Sea.

That's a problem because polar bears are homebodies. They prefer to stay in a specific

range. Throughout the range, they seem to have a sense of place. Now, here we have a situation where

the general pattern of ice drift is westward. So to remain in your traditional range, it means you have to constantly be walking eastward to compensate for that westward drift.
