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.

We don't typically think of living things as falling into this category, but more and more, scientists are programming and designing

living cells and even whole organisms. This area of research is called synthetic biology,

and there's a whole subsection of the field that's all about

figuring out how to engineer cellular armies that can be commanded and controlled.

Cells trained to search out disease tissues.

Cells equipped for environmental reconnaissance.
