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.

J-P. 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.

This is Scientific Americans' 60-second science. I'm Steve Merski.

I think though if genome sequencing just gets super cheap, then it's probably very soon going to make sense to just sequence all your DNA.

Science journalist Carl Zimmer, author of the book, She Has Her Mother's Laugh, The Powers, Perversions, and Potential of Heredity.

Zimmer spoke last month at New York University's Journalism Institute.

Right now, commercial genome services only look at a small percentage of all your DNA,

but as the cost plummets, you'll get your entire genome.

Then the issue will become, well, what do you use your genome for in terms of your health?

A lot of people will actually be benefit from something I learned by looking at my genome,

which is that if, God forbid, I were to get hepatitis, there are certain drugs that won't do me any good

because I have certain genes.

Pharmacogenomics, as it's called.

I think that pharmacogenomics might be the kind

of low-hanging fruit of genome sequencing. Because like doctors so often, like if you get sick,

they're like, well, let's try this. You know, and it might be hepatitis. It might be depression,

all sorts of things. Like, well, that didn't work very well. Let's try this. Wouldn't it be nice if we could just skip the stuff that doesn't work

and go to the stuff that does?

So that might be kind of where medicine goes
