You can't be judgmental about babies. They are all have different needs. I was left with an enduring hatred of cheese because it was forced down me when I was young.

I love the French detective series 'Spiral.' It's quite brutal to watch, but I'm already hooked.

When I grew up, we didn't have a TV, and I think more families today have ambitions of getting out of their environment, such as sending their children to university.

The trouble with climate change is it's an extraordinarily diverse and complex issue, but for example if the BBC would let me make some of the programmes I'd like to make on climate change, I bet you there would be a change of emphasis.

I did not study science at school until I was 13, when I was totally turned on by a seemingly dreary old teacher who suddenly, unannounced, manufactured a huge explosion in the middle of a totally boring monologue. From then on, all of his class wanted to make explosions.

You can now modify the genes of large animals, and the largest animal we are concerned with is the human.

Of course it is a very simple matter to identify genes which might modify intelligence or memory and start thinking about whether you want to enhance a human, and the next generation is going to have to deal with that issue. Should we be trying to enhance humans rather than trying to educate them and so on?

Now we have technology where we can modify the genomics of individuals by gene transfer and genetic meddling, we may find that people will want to modify their children, enhance their intelligence, their strength and their beauty and all the other so-called desirable characteristics.

I don't like seeing myself on television and I don't enjoy filming. What I actually enjoy is thinking about how I am going to express something or how we are going to make the visual metaphor.

When I look in the mirror, I am slightly reminded of self-portraits by Durer and by Rembrandt, because they both show a degree of introspection. I see some element of disappointment; I see a sense of humour, but also something that is faintly ridiculous; and I see somebody who is frightened of being found out and thought lightweight.

About 3 million IVF babies have been born since Louise Brown's birth in 1978. Bizarrely, when this life-giving treatment was first considered, it was massively controversial. A storm of vitriolic protest came from many religious leaders, journalists, politicians, regrettably even other scientists and doctors.

However pragmatic you are, it is very demanding being a new parent.

I don't know whether it is important to study science at a young age, though current thinking emphasises the need.

My first vote was for a communist in east London when I was a medical student. But I've voted Tory, Labour and Lib Dem in my time.

Both in Britain and America, huge publicity has been given to stem cells, particularly embryonic stem cells, and the potential they offer. Of course, the study of stem cells is one of the most exciting areas in biology, but I think it is unlikely that embryonic stem cells are likely to be useful in healthcare for a long time.

It's extraordinary to think that if you walked into a room and said you had never heard of Hamlet, you would be regarded as a Philistine. But you could walk into the same room and say, 'I don't know what a proton is,' and people would just laugh and say, 'Why should you know?'

In reality, both religion and science are expressions of man's uncertainty. Perhaps the paradox is that certainty, whether it be in science or religion, is dangerous.

We are more dependent on science and engineering than at any other time in history. However, there is plenty of evidence that far too many people are scientifically illiterate, often having been put off science at school.

Following 25 children for the TV series 'Child of Our Time' has been extraordinary. The BBC's original plan was to commemorate the new millennium. What better way than to film a number of expectant mums from across the U.K.? Coming from widely different backgrounds, all were due to give birth on January 1, 2000.

The disturbed individual who believes himself to be Christ, or to receive messages from God, is something of a cliche in our society. Ever since Sigmund Freud, many people have associated religiosity with neurosis and mental illness.

Childhood is not dead. Children were worse off when we were hunter-gatherers; they were threatened in medieval times and exploited during the Industrial Revolution. Was it any better in the time of Charles Kingsley or Charles Dickens?

That Britain today is a liberal society is largely because of the philosophy and outlook of the Anglican Church, which did so much to shape our core values in the past few centuries.

Some people, both scientists and religious people, deal with uncertainty by being certain. That is dangerous in the fundamentalists and it is dangerous in the fundamentalist scientists.

I'm a traditional Jew with an orthodox background, and it informs much of my approach to science. Of course I think it's very important that if you have those sorts of backgrounds you don't impose them on other people as a clinician, of course.
