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.

I'm Shayla Farzan.

Every honeybee colony has its own unique scent, like a fingerprint, and bees use that scent to recognize their nestmates,

basically saying, you smell like me, so I'm going to let you into the colony.

But here's the mystery.

If you transfer a baby bee into a new hive, not only does the colony accept it,

but that bee will eventually smell like its adopted nestmates, even though they're not genetically related.

This kind of got us thinking perhaps is not actually the genetics of the bee it's not actually the genetics of the bee,

it's actually the genetics of the microbes that live within the bee. Cassandra Vernier is a postdoctoral researcher at the University of Illinois. She knew gut microbes could affect the scent and

communication of other animals like hyenas. So she and her co-authors designed a series of

experiments to test whether microbes also change the scent compounds coating the outside of honeybees,

known as cuticular hydrocarbons. In one experiment, they fed different gut microbes to newly hatch

sister bees. The bees developed distinct microbiomes, and they also

produced different cuticular hydrocarbon sense. But on the other hand, if they were treated with

different inoculums, they recognized each other as non-enestimates or intruders, and they

attacked each other, usually in the form of biting each other.
