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's 60-second science. I'm Christopher in Taliatta.

Satellite imagery, like Google Earth, makes it easy for ecologists halfway around the world to check up on tropical forests.

See illegal roads and logging, stuff like that.

But the info is limited.

Satellite data often tells you what happens after it's happened.

Rhett Butler, the founder of manga bay.com, that's an environmental science news website.

In a prospective piece in the journal Science, he and his colleagues write that sound recordings

could supplement satellite data as another conservation tool.

You can actually set up alerts, and so you can hear things like chainsaws or gunshots in real time.

So you can get out ahead of a potential deforestation before it occurs.

Small audio recorders, some of which are solar-powered and hooked to cell phone grids for data upload,

also give ecologists the ability to eavesdrop on a jungle's biodiversity over time.

If you're in a primary forest, you'll tend to see all the frequencies of a soundscape

occupied by different species.

So these are insects, birds, calling mammals, frogs, things like that.

As a comparison, here is a forest plot after selective logging, meaning some trees were cut, others left standing.

As you move into a more disturbed ecosystem, you would start to see more gaps across the frequencies
