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.

For as long as we've been sending spacecraft to Mars, we've been finding signs of water.

The red planet's sinuous river valleys, flood-carved canyons, and buried glaciers all hint that it was wet billions of years ago.

Some researchers think that the curiously-flat and sparsely cratered northern lowlands are the remnants of a once-grade ocean. But that ocean's proposed coast varies in height by

thousands of meters, which has made the idea controversial. Now, a team of researchers has found

evidence for ancient tsunamis on Mars, evidence that supports the idea of a vanished

Martian ocean and explains its vertically variable shoreline.

We were trying to find shorelines on Mars, like those we typically see on Earth, which

is consistently distributed along a constant elevation, and that is not what we have found

on Mars, because in the case of Mars, the shorelines were

buried beneath tsunami deposits.

He led a team that used satellite images to identify thick deposits of boulders and silt,

apparently left by two separate tsunamis, a few million years apart, almost three and a half
