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

Ethics is not routinely taught to science students except in medicine, and I think it should be.

We live longer and healthier lives than ever before. Animal research has improved the treatment of infections, helped with immunisation, improved cancer treatment and had a big impact on managing heart disease, brain disorders, arthritis and transplantation.

We can't any longer have the conventional understanding of genetics which everybody peddles because it is increasingly obvious that epigenetics - actually things which influence the genome's function - are much more important than we realised.
