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.

Go get your bolly. Over there! Go get it!

Because a new study shows that puppies are able to track human social cues at just eight weeks of age,

before they've really spent much time with people.

And their ability to do so has strong

roots in their genetics. The work appears in the journal Current Biology. We have known for a long

time that adult dogs are especially skilled in understanding cooperative communication from humans.

Emily Bray is a postdoctoral researcher at the University of Arizona

and the canine companions for independence. So for example, they can spontaneously follow a human

pointing gesture. They're even better at it than apes, which are much more closely related to us

than canines are, evolutionarily speaking. So this makes the question of why. Is it a skill

that dogs pick up simply by spending time with people? Or is it a trait that was selected for

when dogs first became domesticated? To find out, Bray and her colleagues spent time with

375 puppies that were going to be trained to be
