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.

This is Scientific American 60-second science. I'm Julia Rosen. Got a minute?

When an earthquake hits or a volcano erupts, scientists traditionally record the shaking

using a specially designed instrument called a seismometer. These sensors are extremely

sensitive, but they're also expensive and distributed unevenly around the world. So researchers

are working on another strategy to monitor earthquakes, using fiber optic cables,

like the ones that form the backbone of the internet.

So the motions are very clear.

Specifically, you can see the arrival of different bits of the seismic energy from the location

at which the earthquake occurred.

So the P wave and the S wave and the different phases

that move out from the site of rupture in the earth are used by seismologists to locate the event.

And so we can detect the important pieces of information above the noise using the fiber optic cable. And then in that way,

the fiber optic measurement is just as good as a seismometer. Nate Lindsay, a PhD student and

seismologist at the University of California, Berkeley. Here's how it works. The scientists basically

take a snapshot of the fiber by shining a laser

down it and measuring the photons that bounce back after scattering off of small cracks and impurities

in the glass. By doing this tens of thousands of times a second, the researchers can record
