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.

Happy New Year!

The team wishes you a Happy New Year! We want to thank all our users that contribute to a change of research culture by preregistering their animal research. We look back to a successful year 2022. We have updated our website and presented preregistration and multiple occasions. We have intensified our collaboration with the center for open science and and published together common standards for the preregistration of animal research. We look forward to an exciting year with lots of promising events such as the 12th World Congress on Alternatives and Animal Use in the Life Sciences. Do not hesitate to contact us, if you want to get more insights on preregistration and other open science measures in animal research. We are pleased to give a virtual introduction into the topic and to discuss theoretical or practical aspects of preregistration at your institution.
