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.

That was the voice of Frank Drake,

a late astronomer and astrophysicist who was instrumental

in sending what's now known as the Erecibo

message. Here to tell us more about humankind's first attempts at finding intelligent life in the

cosmos and what's changed in the last 50 years is freelance science journalist Nadia Drake.

Nadia, thanks so much for joining us today. Thank you. It's good to be here. Let's start with some basic context for our listeners.

What was Erescebo and what anniversary are we talking about today?

The Erescebo Observatory was formerly the world's largest radio telescope.

And that was until China built their bigger radio telescope more recently. But for many years,

it had been the largest telescope on Earth with a dish that spans 1,000 feet. And it had a very

powerful radar, a transmitter that they used to study bodies in the solar system, actually.
