Accelerated by the digital transformation, Open Science offers a revolutionary method to produce, share and access research results. It allows researchers to collaborate more efficiently, enhances scientific integrity, avoids duplication of resources, and fosters a better and more transparent verification of data and peer-review mechanisms. Find out more about the European Union’s concrete actions to support Open Science, and discover how these principles are put in practice through the “MSCA”, the European Union’s reference funding programme for doctoral education and postdoctoral training.
