Since 1991 the “Linz-Congress” has emerged in Europe as the major scientific event in the field of the 3Rs and in 2019 the EUSAAT 2019 3Rs Congress Linz will be the largest international 3Rs congress. We are particularly pleased that our international partners from Japan, JSAAE, the Japanese Society for Alternatives to Animal Experiment, and from China, CCARE, the Chinese Center for Alternatives Research and Evaluation, will report on their activities in our sessions on “3R Centers in Europe & international”. EUSAAT 2019 is hosting oral and poster presentations to facilitate discussions and the exchange of ideas to actively promote the most advanced non-animal methods in the life sciences. The Scientific Committee has identified the subjects that are currently in the focus of 3Rs research in Europe as well as internationally. In 2019 the EUSAAT Congress features sessions on Refinement and Reduction (e.g. animal welfare of experimental animals, academia and education, ethical and legal issues, drug development and toxicity studies) as well as on Replacement (e.g. disease models based on human cells and tissues, non-animal tools for basic biomedical research, stem cells, bioprinting, ’omics technologies, human 3D tissue culture methods and human multi-organ-chips (MOCs)). Since at EUSAAT 2018 the sessions on establishing 3Rs networks in Europe were most popular, we will have several sessions on this topic as well as a Round Table Discussion. For the first time, we are holding the YOU EUSAAT 2019 events aimed at young and early career scientists (up to the age of 35) working or planning to work in the 3Rs field. We want to encourage the dialogue among young scientists and with experienced mentors from the 3Rs area to facilitate opportunities for establishing professional networks. In particular, YOU EUSAAT 2019 will provide a free and open atmosphere for exchanging ideas and career experiences and networking with each other! We are proud that four distinguished colleagues have accepted our invitation to serve as keynote speakers. In addition, we are honored that both the Bjorn Ekwall Memorial Fund (BEMF) will hold the 2019 BEMF Award Ceremony and Lecture at EUSAAT 2019 and also that the editor of ALTEX will present the award for the best article published in the ALTEX journal in 2018 at EUSAAT 2019. This year we will again host two Round Table Discussions on topics that are of importance for implementing the 3Rs at the international level. The first will cover the “International Impact of Closing Research Animal Facilities in Europe” and the second will be on “Establishing an International 3Rs Centers Network”. EUSAAT is very happy to continue the “Young Scientists Travel Award (YSTA)” program in 2019 and we want to thank the SET Foundation for its generous funding. The YSTA program will provide 20 young scientists with the opportunity to share their ideas on the implementation of the 3Rs in education and novel test systems to reduce the suffering as well as the number of animals in research. The EUSAAT Board is pleased that the number of sponsors of the EUSAAT congresses has continuously increased, since due to their financial support we can keep the scientific standard high and the congress fee low. This is important to attract young scientists from Europe and abroad. Thus, on behalf of the participants, the EUSAAT Board and the Scientific Committee are grateful to our sponsors. Moreover, we are also pleased that the abstracts of the EUSAAT 2019 are again published in ALTEX Proceedings and we thank Sonja von Aulock, the editor and CEO of ALTEX Edition, for her generous support. Finally, we want to thank our colleagues on the EUSAAT Board and the Scientific Committee for their continuous support in planning the EUSAAT 2019 congress.
