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.

and are more likely to sire offspring with their favorite female fruit funnaglers.

That's according to a study in the journal Current Biology.

A couple years back, researchers noticed that in fruit bat colonies,

some bats forage for food while others simply snatch it from the

forager's mouths.

And there are different hypotheses for explaining this.

Yossi Yavelle of Tel Aviv University has studied these bats for years.

Well, maybe the scroungers were relatives, he says, or maybe they're just socially dominant bullies.

What we observed is that mostly scoundgers are females.

Well, that got the researchers thinking about something of great importance to most animals,

Specifically, we are wondering whether females might then mate with males that provide them with food.
