Open Science is being heavily promoted by the European Commission and is aimed to be the new way for researchers to do science in Europe. Yet the majority of researchers are not practising Open Science and are not even aware of what Open Science actually is. This talk looks at the various aspects of Open Science and discusses the results of a European survey on Open Science. The survey focused on Open Access and Open Data from the perspectives of researchers in Europe. This talk will specifically address Open Access and Open Data for early-career researchers and will propose recommendations to help implement Open Science as well as mentioning some good practices.
