My name is Jenny and I am a developmental biologist. It’s a hopeless addiction, brought about by the awe inspiring process of making a baby. Get you mind out of the gutter! I’m talking about the process by which a single egg cell, fertilised by a single sperm, grows and divides over and over again to make the 100,000,000,000,000 cells present in a human body. What’s more, these cells don’t just replicate but also somehow organise themselves into lungs, a heart, bones, blood, eyes, a brain and much more. The day that I realised that I could get paid to spend my time trying to understand how this happens was the day I felt that I was finally onto a winner.
