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.

Honeybee stings are painful, but they're also fragrant.

If a beekeeper got some stings from honeybees, it smells like banana.

Dr. Steven Duttrell, a plant ecologist at the University of Salzburg in Austria.

That banana scent, he says, is a compound

called isoamyl acetate, also known as banana oil. It's one of the many compounds produced when a

bee stings, a mix of alarm pheromones that let the hive know that another bees in danger. But that

chemical cocktail doesn't just attract other bees. It also draws tiny flies, known as kleptoparasites.

Or so-called food dealers.

The flies feed on the drippings of bees being devoured by spiders,

and they sense the bees' chemical calls for help as a dinner bell.

Turns out, though, it's not the flies, but a flower that has

the last word in this tale of trickery, because researchers have now discovered that the flowers

of a South African plant, called the parachute plan, produced nearly three dozen of the 90-some

compounds in that honeybee alarm call, meaning they mimic the scent of a honeybee

in danger, to lure in and temporarily trap the flies as a pollination ploy.

The findings are in the journal Current Biology.
