For our second episode we invited German neurobiologist Björn Brembs. In the first part (from four) we discussed his scientific background in neurogenetics and research on the fruit fly and snail behaviour. Björn also told us about his way to the Open Science movement. Upon the development of his academic career he realised that there is no digital infrastructure using which he can store his results, data, code and share with other scientists. In addition, he found that the current academic publishing process is fully controlled by the commercial companies. For him Open Science means not only the openness in sharing information, it means the creation of a tool that needs to be used correctly in order to make scientific findings available for everyone.
