The Hormones Zone was a themed zone part-funded by the Wellcome Trust and the Society for Endocrinology and four of the participating scientists (Saffron, Partha, Craig and Amy) were members of the Society. The zone was very focused on its theme and there was a relatively high number of answers from the scientists (816), resulting in each question receiving two answers on average.
Popular topics in the zone were sperm, muscle and diabetes. It was notable that Laura attended all but one live chat, sometimes as the only scientist present, and she dealt very well with some very busy situations.
