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.

I love a short, cold water swim in Puget Sound in Washington State.

I start from a rocky shore near my home.

If I kept swimming just another hundred feet out, I could dive a few feet down through these clear waters into an underwater forest where animals such as shrimp, crabs, and small fish, like lynchod, rockfish, and maybe even salmon, like to live.

Kelp forests are made of thick, undulating ribbons of brown algae that hang on to rocks at the seafloor and grow toward the light above.

Kelp is found in dense groups like trees on land, hence the name forests.

But just like forests on land, lately these underwater forests have come under threat from climate change.

The kelp forests off California's coasts have largely disappeared in recent years.

It all started in 2013 with a mysterious blob. That's what

scientists called this blob-ish patch of warmer than normal ocean water, which was created by

changes in the atmosphere above the Pacific. The blob brought drastic changes to the California

kelp forests. Elevated ocean temperatures led to a die-off of sea stars.

Sea stars typically control the population of sea urchins. Sea urchins eat kelp. And so, the coming of the

blob created an explosion of urchins. The creatures went on an eating spree that, by some estimates,

cleared 96% of the kelp from beneath the California coast.
