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.

J-P. That's Y-A-K-U-L-T dot-C-O-J-P. When it comes to a guide for your gut, count on Yacult.

This is Scientific Americans' 60-second science. I'm Steve Merski.

This year's prize is about harnessing the power of evolution.

The Royal Swedish Academy of Sciences has today decided to award

2018 Nobel Prize in Chemistry with one half to Francis H. Arnold for the directed evolution of enzymes.

And the other half, jointly to George P. Smith and Gregory P. Winter, for the phage display of

peptides and antibodies. Joran Hansen, Secretary General of the Academy earlier today.

Francis H. Arnold was born in Pittsburgh, Pennsylvania in the United States in 1956, and she's

currently at the California Institute of Technology, Caltech in Pasadena in the Los Angeles area.

George P. Smith was born in 1941 in Norwalk, Connecticut,

and he's currently at the University of Missouri in Colombia in the United States. Sir Gregory P. Winter

was born in 1951 in Leicester in the United Kingdom, and he is at the Laboratory of Molecular Biology and the University

of Cambridge in England.

So with that, I'd like to ask Claude Gustafsson, Chairman of the Nobel Committee, to make

some remarks about the prize.

So thank you, Your Honor.

So this year's prize in chemistry rewards a revolution based on evolution.

Our laureates have applied principles of Darwin in the test tubes and used this approach to develop new types of chemicals for the greatest benefit of humankind.
