Animal welfare scientists have long suggested that the constrained lives of lab animals could affect the quality of the data they yield. Some biomedical researchers have now added their voices, raising concerns about obesity and chronic cold in researchrats and mice respectively. Work by the PhD student Jessica Cait also recently ran meta-analyses showing that compared to well-resourced (or 'enriched') conditions, conventional housing conditions increase the severity of induced anxiety, cancer, cardiovasculardisease, depression and stroke, and enhance all-cause mortality (Cait et al. 2022). This work also echoed previous findings that research animals are male biased, leading us to label them 'CRAMPED' (cold, rotund, abnormal, male-biased, enclosed and distressed). But would improving housing conditions, and moving away from CRAMPED subjects, change research results? Some are scared by this possibility. However, it could represent an opportunity to improve the currently poor rates at which data from animals successfully translate to humans. I will present results from our new meta-analyses showing the extent to which housing quality can affect the conclusions drawn from studies of disease modifiers (e.g. therapeutic drugs). These results show that reporting housing conditionsis essential if research replicability is to be improved, and that welfare status, like sex, should be considered a 'biological variable' that can affect the generalisability of research findings.
The Bf3R seminars address issues related to the use of animal experiments and alternative methods in basic research and toxicology, as well as the 3Rs. They include a lecture of approx. 30 – 60 min, followed by a discussion.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
