Biological Variation and Reproducibility


Published on: Tuesday, November 30 2021 12:00:00 PM


In order to build a solid foundation for subsequent studies, it is a prerequisite that scientific results must be reproducible. However it is often found that there studies claiming a significant result are not reproducible. This lack of reproducibility was also described in a survey published 2016 in Nature, where more than 70% of researchers have failed to reproduce another scientist`s experiments and more than half have failed to reproduce their own experiments1.

During the 3Rs days, Dr. Bernhard Voelkl from the University of Bern gave a presentation of his work on reproducibility issues in animal experiments and how these can be counteracted2,3. Together with Prof. Hanno Würbel, a video has been produced as part of this work through support from the Swiss National Science Foundation, the NC3Rs and the European Research Council, which is intended to illustrate the problem and show researchers possible solutions for their own projects.
