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.

This is Scientific Americans' 60-second science.

I'm Steve Merski. Got a minute?

When we were first proposing the mission, NASA called for not just to fly by a Pluto, but further study of ancient Kuiper Belt objects, the building blocks of the small planets of the solar system.

And so we designed the spacecraft to be able to do that.

Alan Stern, principal investigator of NASA's

New Horizons mission that zipped past Pluto July 14th. He spoke October 11th at the Science Writers'

2015 meeting on the campus of MIT. Now we have to go to NASA with a funding proposal to make this

real, but we've already found our targets.

The extended mission that we plan to fly

that we will propose next spring to NASA

will result in a flyby of a small Kuiper Belt object

on January 1, 2019.

We found these targets with the Hubble Space Telescope. They're very faint. They're very

hard to do. You can't find them from the ground. We had five potential targets. We ended up

selecting the one that we want to fly to in August. And in fact, in just over two weeks,

we'll be firing the engines on New Horizons to retarget in that direction for that flyby.
