"If someone cares about it, there is a podcast about it", says Lewis MacKenzie a postdoc researcher in biomedical optics. He recently published a paper about science podcasts: Science podcasts – Analysis of global production and output from 2004 to 2018. We talked about his research, methods, data basis and of course, the outcome of his study. How many science podcasts are there and what characterizes them? This study, as Lewis MacKenzie states, provides the first ‘snapshot’ of how science podcasts are being used to communicate science to public audiences around the globe.
