There is a new way with very very tiny fiber optics, which give an enormous high resolution. There are many many thousand fibers, very very close together with a very small diameter.

That's the new way - with computers, computers, computers. That's the way we can have the cell survive and get some new information in high resolution. We started about five years ago and, today, I think we have reached the target.

Fiber optics have linked the world together and made our world, our planet, basically one small place. If it weren't for fiber optics, we wouldn't be able to have inexpensive global phone calls or 200 cable channels on our televisions.

Fiber optics got slammed last week,

We sometimes freeze the specimen with liquid nitrogen, which is extremely cold, you know. This is another technique we use now - but the specimens are not alive.

And my real enemy is not to hold the specimen sterile, but it's the lighting. The light is our real enemy. So we have to work with very very poor lighting. But we can increase the light with computers.
