The call for STSMs 2015 is open

Short-Term Scientific Missions – These Inter-laboratory Exchange Visits aim for strengthening the existing COST Actions by allowing scientists to go to an institution or laboratory of another COST country to foster collaboration, to learn new techniques or to take measurements using instruments and/or methods not available in their own institution/laboratory. They are particularly intended for Early Stage Researchers.
The call for STSMs is open until 30th June 2015. See how you can participate here
