Summary

What if you could know exactly how food or medication would impact your health -- before you put it in your body? Genomics researcher Jun Wang is working to develop digital doppelgangers for real people; they start with genetic code, but they'll also factor in other kinds of data as well, from food intake to sleep to data collected by a "smart toilet." With all of this valuable information, Wang hopes to create an engine that will change the way we think about health, both on an individual level and as a collective.

This TED Talk features genomics researcher June Wang, recorded live at TED 2017.

0:07.0

Today I'm here actually to post you a question. What is life?

0:13.0

It has been really puzzled me for more than 25 years,

0:17.0

and probably will continue in doing so for the next 25 years. This is the thesis I did

0:23.2

when I'm still in undergraduate school. When people, while my colleagues, my classmates,

0:31.1

still treat computer as big calculator, I start to teach computer to learn. I built a digital native beetles

0:40.3

and tried to learn from real native beetles

0:43.3

just to do one thing, search for.

0:46.3

And after a very simple neural network, genetic algorithms and so on,

0:51.3

look at the pattern, it almost identical as the real life.

0:57.9

A very striking learning experience for 20 years' boy.

1:03.5

Life is a learning program.

1:07.7

When you look at all those wonderful world, every species has its own learning program.

1:15.5

The learning program is genome, and the code of that program is DNA.

1:22.4

The different genome of each species represent different survival strategy.

1:29.6

It represents hundreds of millions, years of evolution.

1:34.8

The interaction between every species' successor and the environment.

1:41.3

I was really fascinated about the world, about the DNA,

1:45.0

about language of the life, the program of learning.

1:50.0

So I decided to co-founded the Institute, to read them, I read many of them.

1:57.0

Probably we read more than half of the plant animal genomes in the world, I mean, up to date.

2:04.6

We did learn a lot. We did sequence also one species many, many times, human genome.
