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.

Robin Hood famously stole from the rich and gave to the poor.

Young newly hatched barn owls do something similar.

On average, barn owls raise six chicks at once, and sometimes as many as nine.

But they don't all hatch at the same time, which means the older owlets are generally larger and healthier than their younger brothers and

sisters. As long as the little owls remain in the nest, they're completely dependent on their

parents for food. The problem is that the small rodents they eat can't be split up.

So when mom or dad returns to the nest to feed their offspring, only one chick can eat at a time.

In many bird species, the oldest would simply outcompete the youngest.

But barn owls are different.

Turns out if the older, healthier birds sometimes donate their meals to their hungrier siblings.

Adults in other animal species share their food.

It's mainly observed when males want to reproduce with females, so there is many exchange of food.

Or in primates, there is many exchange between food and

grooming, but only in adult. Evolutionary biologist Pauline DuCore, from the University of Lausanne

in Switzerland. And in chicks, it's really rarely observed, so it's quite impressive that in this species, there is so many cooperative behaviors.
