The COSY community gathered in Madrid for its 4th General Meeting.

From 27 to 29 April 2026, researchers and experts from across Europe came together at the CSIC Central Campus in Madrid for the 4th COSY General Meeting (FOURTHCOSY): three days of science, collaboration, and shared progress.

The meeting brought together the full COST Action CA21101 community, with working groups, plenary sessions, and the kind of face-to-face exchange that no video call can quite replicate.

As the group photo in front of the CSIC headquarters shows, the COSY network keeps growing, and so does its momentum.

A sincere thank you to all participants, speakers, and organizers who made FOURTHCOSY a success. The next steps start now.
