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.

I'm Christopher in Thalata. Got a minute?

Saturn's largest moon, Titan, has a thick atmosphere, clouds, complex organic molecules.

NASA has called it one of the most earth-like worlds we've found to date, with one glaring exception.

It's awfully cold down there.

It's about 94 degrees Kelvin, which means that water would be a rock.

Paulette Clancy, a chemical engineer at Cornell University.

At temperatures that cold, minus 290 degrees Fahrenheit,

one of the most basic biological structures, the cell membrane, can't exist,

because to form, the oily membranes depend on the presence of liquid water.

That said, Titan does have plenty of liquid to go around, but it's liquid methane.

So Clancy and her colleagues use computer models to determine whether any molecules on Titan

might mimic the membrane-forming compounds here on Earth.

Based on a catalog of organics observed by NASA's Cassini mission, they found a candidate,

Acrylo-Nitrile.

Its internal electrical charge distribution would allow it to self-assemble into membranes,

just like phospholipids do here on Earth.
