Between 2008 and 2013, the Instituto Ciência Hoje published one of the first science communication podcasts in Brazil, Estúdio CH. Initially, itwas hosted and produced by Mariana Ferraz. From October 2009 onward, I took the reins, always with technical support from Octavio Aprigliano. I am trying to convince the institute to make all the content available on the internet. Meanwhile, here are a news story I wrote when we reached the one hundredth program and the mp3 file of that specific podcast.
