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 Americans' 60-second science. I'm Sarah Vytak.

Charles Darwin's famous trip on HMS Beagle is primarily known for bringing us the concept of evolution.

But Darwin also investigated coral reefs and their formation.

One thing about reefs in particular really confused him. That conundrum became known as Darwin's

Reef Paradox. The paradox is this. How can you find this lush teeming of life in the other ways

nutrient depleted ocean.

That's Dr. Christian Wollstra, a professor at the University of Constance in Germany.

And the trick is symbiosis.

Corals are basically sessile organisms or animals.

So they basically pick a place and they sit and then they cannot move.

So the way they make a living is that they team up with microalgae inside their tissues.

And this is essentially tiny plants that do photosynthesis.

And this photosynthesis generates sugars.

And these sugars will be essentially delivered to the coral animals.

These little critters across the globe are in a lot of danger.

According to a report from the global coral reef monitoring network

published in October 2021,
