The only way to find out which half is wrong and which is right, is by disproving existing ‘truths’ and replacing them with new ones.
The majority of young scientists working in research have only ever been that – scientists. But Vienna Leigh reports how one group leader at the European Molecular Biology Laboratory started his career at the front of a classroom – and feels that his science benefits as a result.
