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.

Hey, it's Rachel, and I am here in a bunny suit at MIT Nano with Professor Vladimir Bolivich, who is going to show us around.

Well, it's a pleasure to have you here. Thanks for coming.

Goal of this space is to enable anyone to build anything they wish.

Hey, it's still Rachel, but now I'm here at the Scientific American Recording Studio.

As you just heard, today's episode is a little different from our standard

format. We went all the way to Cambridge, Massachusetts to explore MIT's cutting-edge nanotechnology lab.

You'll notice that our sound quality is a little lower than our usual standards, but that's just

because we were surrounded by actual scientists doing actual science, along with all of their exhaust fans and

fume hoods, of course. If you want to see all the cool stuff we're talking about during today's

episode, including, of course, me and a full bunny suit, you can check out a video version over on

our YouTube channel. You'll find a link to that in our show notes. Okay, let's dive back into

our Surrounded by Big Science Machines immersion pod.

You were joking earlier that if you have allergies, this is the place to be.

And I'm very allergic to dust mites, and I have noticed that I am breathing easier than normal.

Well, I'm glad you say that, because you're then a true proof of our numerical counting,

because we do control for the dust particle count continually.

We do speed up and slow down our purifying fans in order to make sure we are at a class 100 or better. And what that means is that in a cubic foot of air, there are 100 particles bigger than half a micron.
