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.

But don't get distracted, because one of those gulls may soon go after your food.

There's a very small proportion of extremely bold individuals that seemed to ruin the

reputation of the whole species. Neltschebogert, an animal behavior researcher at the University

of Exeter. She studied the food snatching habits of gulls in seaside towns in the southern UK,

and she found that very few, only the boldest, would actually take the bait, or make that the bite.

The experiment went like this.

A researcher crouched near a gull and then set out a plastic bag of french fries.

For those brave gulls that then started to approach, the researcher either stared straight at the gull, as in I see you thief, or the researcher simply looked away.

And it turns out staring down the gulls made them hesitate 21 seconds on average before approaching the fries. The results are in the

journal biology letters. And gulls aren't the only ones who behave better when being watched.

A 2006 study found that people paid three times as much for their drinks at an

unattended honor system coffee bar when just an image of staring eyes was displayed nearby.

As for the gulls, Bogart points out that we need to learn to live with them because the
