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.

Yachtold 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 Americans' 60-second. I'm Sarah Vytak.

Modern medicine and bacterial pathogens are in an arms race. We use antibiotics to keep them at bay,

and then they adapt to become immune to those antibiotics,

evolving into superbugs.

The battle has been an asymmetric one.

We just don't have that many options in the fight.

Most of our antibiotics come from bacteria, the vast majority from a single genus, streptomyces.

And most antibiotics use the same handful of strategies to attack bacteria.

But there's a reason that we only use a tiny fraction of the antibiotic chemicals that exist in nature.

This search for completely new substances was unsuccessful for the past 30 years.

It's very difficult to make sure that we find an antibiotic,

so a substance that produced by microorganisms and that's toxic to other microorganisms,

but that is not toxic to humans. Miriam Rosenbaum is a professor of synthetic biotechnology

at the Hans-Noll Institute in Germany. But how, if they're so hard to find,

do scientists know that we have only found a tiny fraction of the antibiotic substances that exist

in nature? We do know that, because for the past 20 years, we were in this biological revolution of sequencing.
