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.

I have the instruments, ideas, technology, computer techniques. We try to create or see something, which has not been known before - just to discover something together. This is always my dream.

Of course, today at the Karolinska Institute, I am working with some top experts - even some Nobel prize winners. They have the latest news and I have the technique.

It's to surprise people about something that is extremely well known. I mean human reproduction, the human body, nature and so on. To surprise them with a new technique.
