This week, we hear from the University of Florida’s Dr David Duffy. He heads up a team of researchers who are studying sea turtles. In order to track the animals and their diseases, the scientists devised a method of collecting fragments of DNA from tanks at the university’s turtle hospital, as well as from sand and water in the local environment. While they found plenty of turtle DNA, they were surprised to uncover large amounts of high-quality human eDNA. Duffy tells us all about the study and his surprising findings, but also highlights the ethical problems this could raise. We are then joined by Dr Matt Clark from the Natural History Museum, and Sir Jonathan Montgomery from University College London, to discuss the ins and outs of eDNA – how it can be beneficial for conservation, forensics and healthcare, but could also be problematic from a privacy perspective. Muriel Rabone and Dr Adrian Glover from the Natural History Museum have compiled an extensive checklist of all the species present in the remot
