Here's one of the latest illos for Big Picture 7 for Wellcome Trust. Following hot on the heals of Big Picture 6 (see below) this time the subject is Drug Development. An idea was needed to show the different ways a drug will protect a cell. Some repel attackers, some fight them inside the cell and some protect the core of DNA. Seemed to lend itself to a castle idea! It'll be out in December and the pdf will be downloadable on their website (in my links list) along with the other 6!
