Hello, welcome to the naked scientist.

0:19.8

This is the show where we bring you the latest breakthroughs in science, technology and medicine

0:23.9

with me Chris Smith and coming up what the structure of your retina reveals about your risk of developing

0:29.8

a range of different diseases have we finally cracked how the first biological cells appeared

0:34.9

four billion years ago or so, and how Ponskateers survive potentially lethal run-ins with big raindrops.

From Cambridge University's Institute of Continuing Education,

this is the Naked Scientists. Now first this week a new study has found that the structure of the retina at the back of the eye can reveal a host of different diseases that a person

is at risk of developing.

1:06.8

By using machine learning to marry up changes seen in retinal images with health and genetic data taken from tens of thousands of people who participated in the UK's biobank study.

1:19.0

Mass Iron Ear Hospital ophthalmologists, Mariam Zekevat, and Nasley Zebedast, think that they have come up with a way of using

1:26.1

the retina to see what a person's future health looks like.

1:30.3

In recent years, we have come to realize that we can find out a lot more information from images of the eye than we ever thought was possible.

1:40.0

And it's opened up this really exciting area of research.

1:44.1

And we were fortunate enough to have access to an incredible resource, specifically a large, large study
