Why are women deserting sciences in droves? Is it unconscious bias, a lack of aspiration, lack of confidence - or just lack of ability? Are we failing our daughters, or is this just the way things are? With females making up half of the population, a lot of science, maths and engineering talent is going to waste. Help Dr Clare Taylor (Edinburgh Napier University, ScienceGrrl) and Dr Pam Cameron (Novo Science, Science Grrl) figure out why the pipeline is so leaky and what, if anything, we should do about it.
