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.j.p.

quickly, I'm Rachel Feldman. Associate News editor Alison Partial is joining me today to tell us more.

So, Alison, what are we talking about when we talk about nukes in space?

Yeah, it's definitely worth being specific. But like what we're talking is specifically about nukes in space. Yeah, it's definitely worth being specific. But
