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.

In addition to giant crustaceans and creepy anglerfish,

the deep oceans hide a vital piece of technology,

the cables connecting almost every continent, island, and archipelago to the internet.

But it seems those undersea cables can be used for more

than just sending cute cat memes around the world.

We can do a good job picking up earthquakes using offshore cables.

Jonathan Aho Franklin is an applied geophysicist at Rice University and Lawrence Berkeley National Lab.

He says that fiber optic cables are like threads of glass, and there are impurities built in.

So when you shoot lasers through the fibers, those impurities backscatter some of the light right back to the laser source.

And we make measurements of the change in the backscatter light over time,

which gives you information on the stretch of the cable at each location.

His team took advantage of a brief maintenance period

when a particular cable off the coast of Monterey, California,

was not being used for communication.

The researchers studied the slight deformations in the cable

and were able to sense a small earthquake,
