This summary is the first in a series of SAPEA Insights. It provides highlights and key messages from SAPEA’s ‘Crossing Boundaries’ conference, which was hosted by the Estonian Academy of Sciences.

The summary outlines the contributions made by the speakers and the discussions that followed in each of the sessions. This document aims to summarise the conversations throughout the day and therefore does not necessarily represent the views of SAPEA, the European Academy Networks or their member academies. The report reflects only the authors’ views. The European Commission is not responsible for any use that may be made of the information it contains.
