Your contribution
to better science is an online registry for scientific studies involving animals conducted around the world. It is operated by the German Centre for the Protection of Laboratory Animals (Bf3R) at the German Federal Institute for Risk Assessment (BfR). The registry was launched as a reaction to the translational and reproducibility crisis and provides scientists a platform to register an exact study plan prior to the start of experiments in order to prevent selective reporting. This allows reviewers or other scientists to compare the initially registered contents with the final publication. Thereby, encourages transparency, reproducibility, and animal welfare.

Latest News at the Bundesnetzwerk 3R

Join us at the next event of the German Bundesnetzwerk 3R on November 30. We will present our preregistration platform We are also looking forward to the presentations of other tools that support scientists in planning and conducting their animal study such as SMAFIRA, a searching tool for alternative methods or CIRS-LAS a reporting system for the recording and analysis of unplanned events in animal experimental research. The talks will be held in German. The registration is now open.
