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.

This is Scientific American's 60-second science. I'm Christopher in Taliatta.

We humans used to think that our ability to use tools made us different from all other animals.

But then we found out chimps used tools too, such as twigs, to gather termite snacks and rocks to hammer open nuts.

And some birds use tools, like brainy, new Caledonian crows, which can assemble multi-part tools to solve open nuts. And some birds use tools, like brainy New Caledonian Crows,

which can assemble multi-part tools to solve puzzle boxes presented to them by researchers. Well,

now we've learned that a different group of birds, sea birds, can also use tools. Scientists spied

on Atlantic puffins, the distinctive tuxedoed birds with bright orange beaks,

and in 2014, the observers spotted one floating on the sea off whales, scratching its back

with a stick. Then in 2018, the researchers caught another tool using puffin on camera,

on Iceland's Grimsy Island. In a short video clip, a puffin can be seen grabbing a stick with its beak and then using it to

scratch its chest, perhaps to dislodge one of the seabird ticks infesting the island that summer.

The details about puffin proficiency are in the proceedings of the National Academy of Sciences.

Study author Annette Fayette said Scientific American in an email that these two

instances don't prove that seabirds are highly intelligent, though they could be smarter than we thought.

But what is certain, she says, is that puffin populations are crashing, and it's largely the fault of

us and our tools, which have led to overfishing, climate change, marine pollution, and the

presence of invasive species, all of which make seabird life harder. It would be nice to keep
