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.

How do you make a piece of glass repel water? How do you protect metals from harsh chemicals? Scientists have

been puzzling over how to transform surfaces for centuries. Jacob Sagiiv made a giant step

forward in this field of research by discovering a way to transform a solid surface with an ultra-thin

layer of molecules. He shares the Cavley Prize in nanoscience with

Ralph Nuzzo, David Alara, and George Whitesides for discovering and applying an approach

that's been used in everything from batteries to car windshields to dental implants.

Scientific American Custom Media, in partnership with the Cavley Prize, spoke with Jacob

to learn more about his contribution to this work. Jacob Sagiv knew he wanted to be a chemist

since he was a kid. I played chemistry since I was 10 years old. But of course, when you say

chemistry, what you think? You think about test tubes, boiling something, putting liquid from one bicker into another bicker.

By the time he was in graduate school, Jacob had evolved from playing with test tubes to manipulating molecules.

The dream of chemistry is to have a handle on each molecule to be able to put it in the right place and to build with molecules.

This is the ultimate goal that every chem is to dream about.

So far, Jacob had tried out different ways of arranging molecules by dissolving them into thin plastic film.

He found if he stretched this film, the molecules would line up and he could measure them.

It's in a solid, which is a polymer, and you can have some control on how these molecules are

organized by doing this.
