1. [GAPG-1] Reinforcing the COST Action dissemination strategy. To disseminate the achievements of Short-TermScientific-Missions Grantees, mostly young
researchers, via a focused event where the Grantees will be invited to 2-3 minutes interviews. These interviews will be recorded and promoted in the social media. The planned virtual Training School will also include a focused session for training young researchers in communication skills. Science Webinar Series will continue and overview lectures on COST Action achievements by leading experts from the network will be delivered.

10. [GAPG-10] FemCOSY Group Goal. During the 3rd grant period, FemCOSY will analyze the survey from the 2nd Grant Period to address gender imbalance in scientific fields, organizing the 3rd online FemCOSY Meeting with both male and female participants and speakers, and discuss survey results and potential follow-up surveys before publishing the findings. Goals include increasing female participation to 39%, male involvement to 30%, and achieving 100 attendees. The LOS will support dissemination and may seek for funding a specialized survey tool if needed.
