It is important that legislation keeps pace with scientific progress.

I think it's important for scientists to be a bit less arrogant, a bit more humble, recognising we are capable of making mistakes and being fallacious - which is increasingly serious in a society where our work may have unpredictable consequences.

Robots may cut down on infection and mean a consultant can see more patients, but wouldn't you rather meet the doctor than a machine?

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.

My own field, the prevention of genetic disorders in babies, has been possible only because of humane work on animals.

It is time my colleagues got real. All British universities doing worthwhile research use animals, and, instead of hiding, they should be boasting of their achievements.

I don't believe the fertilised egg can be equated with the sort of human life that you and I represent, or our children represent.
