Laetitia Chauve鈥檚 image, with support by Simon Walker and Chieko Itakura from the Institute鈥檚 Imaging facility. This picture is a scanning electron micrograph of the head of an adult C. elegans worm magnified by 7,190 times. The raw image is greyscale but has been coloured post-image capture to highlight the six symmetrical inner lips (yellow/red) surrounding the opening of the mouth and the amphids (primary chemosensory organs; blue). Debris and/or bacteria (which C. elegans eat) have been coloured purple. Laetitia, a member of the former Casaneuva lab, studied C. elegans to investigate the link between diet and ageing.
