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.

A physics lesson may be the last thing on your mind as you relax at the ocean.

However, if you're sitting on a lovely Hawaiian beach with your Mai Tai and you're looking offshore

and you see 20-foot waves and people surfing on them and you notice that it's only lapping up on the shoreline

here with teeny little waves, that's the reef working to dissipate that energy.

Mike Beck studies the intersection of engineering, ecology, economics, and finance at UC Santa Cruz,

and he says reefs act a whole lot like our human-built coastal infrastructure

to tame the energy of incoming waves.

They essentially act just like a low-crested submerged breakwater.

That's an engineering term, but it means that there are really good engineering models for

describing the benefits of reefs.

And those models are the key behind a new report from the U.S. Geological Survey, with Beck

as one of its authors.

The researchers modeled hypothetical storms hitting coastlines in areas with offshore reefs,

like Florida, Hawaii, and Puerto Rico.

They studied how reefs of various heights would dampen waves and hold back flooding.

And they found that every
