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.

So the Internet is really a network of networks that underlies critically so many things in our lives. But really 50 years ago, it was an experiment that escaped from the lab. And it wasn't really designed to be the global communications infrastructure it is today.

Jennifer Rexford, a computer scientist at Princeton University specializing in computer

networks. She spoke to Scientific American Editor-in-Chief Marriott de Christina at the recent

World Economic Forum in Davos. So it really planted the seeds of tremendous innovation around

the periphery of the internet and the devices we connect to it and the applications we run over it.

But ironically, it didn't plant the seeds of its own innovation. And we suffer from that every day,

from the fact that we have denial of service attacks, taking down websites, we have performance problems,

Netflix streams grinding to a halt and so on. In my work on self-driving networks,

we're bringing together

two really exciting technologies, machine learning that's transforming everything by taking raw data

into true situational awareness. And the second is programmable network switches that bring the same

idea of enabling and lowering the barrier to innovation that we have at the outside of the

internet to its basic underpinnings so that we can learn how to sense and actuate better over time

so that the network can learn to detect performance problems and route around them,

to detect denial of service attacks and block them before they do significant harm.

So the marriage of these two technologies is really happening now,
