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. To learn more about Yachtold, visit yacult.co.com.j

That's Y-A-K-U-L-T dot-C-O-J-P. When it comes to a guide for your gut, count on Yacult.

For Science Quickly, this is Rachel Feltman. In our last few Friday fascination episodes,

journalist Sophia Mochino has taken us along for her ride on the Nathaniel B. Palmer,

an icebreaker traveling through the southern ocean. Today marks the end of our journey with

Sophia, so if this is the first time you are hearing about Antarctica in our feed,

definitely go back and catch up.

In today's episode, Sophia speaks with some of the scientists on the icebreaker

as they make their way back home,

and as they grapple with how to feel about the beauty and horror they've witnessed at sea.

Thank you. at sea. After spending two months traveling through West Antarctica's Amiton Sea on board the Nathaniel B. Palmer, we are approaching the end of our expedition. Researchers collected sea ice and thousands of gallons of sea water at 27 different spots in the ocean surrounding Antarctica.

Those samples allow them to examine different biogeochemical processes, some of them linked to climate change and the future of our planet.

We endured bad weather in our quest to reach certain places.

One of them was Pine Island Bay, a remote coastal area of West Antarctica that is usually blocked by sea ice, even in the summer.

We mentioned Tweed's Glacier, even in the summer.

We mentioned Tweed's glacier, nicknamed the Doomsday Glacier, in episode 1.

Pine Island Glacier is melting at a similarly rapid rate, discharging lots of glacial ice

into the bay.
