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.

I have some friends, colleagues here at the Karolinska Institute and even in the United States and many other countries too, because we are working together as scientists.

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.

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.

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.
