Biological Sciences Section The Biological Sciences Section organised the following event at the 2016 British Science Festival:Social egg freezing: motherhood on ice Egg freezing is a new technology increasingly touted as a game-changer for women wanting to delay motherhood. How does it work and what are the social implications of the procedure? The Society for Endocrinology’s panel of hormone and fertility experts debated these questions. President 2016: Dr. Channa Jayasena, Imperial College London President 2015: Professor Helen Roy, Centre for Ecology and HydrologyGroup Head and Principal Scientist, Professor Helen Roy leads zoological research within the UK Biological Records Centre (part of the NERC Centre for Ecology & Hydrology), which is the UK focus for terrestrial and freshwater species recording. Helen’s work focuses on the use of large-scale and long-term datasets on the distribution and abundance of species to understand and predict the effects of environmental change on biodiversity. The current focus of her research is predicting the biological impact of invasive alien species (IAS). Helen has worked on IAS for 10 years and as a community ecologist for 20 years. She is responsible for maintenance and further development of the Delivering Alien Invasive Species Inventories for Europe (DAISIE) web database, and the GB-Non-Native Species Information Portal (GB-NNSIP). She is the chair of the newly formed COST Action ALIEN Challenge (TD1209) which has been implemented to link and analyse information on IAS across Europe. Helen also has extensive expertise in citizen science and recently led a major review which was published both as an extensive report and a guide to citizen science. She has recently been awarded the Zoological Society of London prestigious Silver Medal in recognition of her contribution to understanding and appreciation of zoology, recognising her leading role in science communication. President 2014: Nessa Carey Nessa Carey is the International Director at PraxisUnico and the author of the popular science books The Epigenetics Revolution and Junk DNA: A Journey Through The Dark Matter Of The Genome. She has held a number of senior scientific positions in the biotech and pharmaceutical industries and is a former academic at Imperial College, where she is now a Visiting Professor. Recorder: Dr. Penny Fletcher, Royal Society of Biology Penny Fletcher is the Events & Public Engagement Manager at the Royal Society of Biology, a role she has held since July 2013. Penny has experience in developing and delivering science and engineering-related public engagement projects in her current role and previous roles including outreach events for schools and public audiences during her PhD on pollination ecology (2007 -9) and when she worked as the National Science & Engineering Week Project Manager at the British Science Association (2011 – 13). Penny has also organised interactive science activities for family, adult and school audiences at UK science festivals including the British Science Festival, Cheltenham Science Festival, The Big Bang Fair and Green Man Festival. As part of her current role Penny is working with the Society of Biology’s Public Engagement Working Group on collaborative public engagement activity. The group also operates as the biological sciences section for the British Science Festival. Penny also oversees the Society’s regional work, which includes volunteer-led grassroots public and scientific events, many of which take place during the annual Biology Week.
