The Science Room highlights the work of the Dr Hadwen Trust for those in the biomedical community keen to know more about non-animal research, and aims to stimulate thinking to address biomedical issues from new perspectives. The Dr Hadwen Trust's mission is to advance the development and acceptance of non-animal techniques to replace animals in biomedical research. To achieve this we fund a programme of research projects to develop alternative methods, which combine the highest humane principles with the best scientific standards. The Trust also actively promotes the wider use of non-animal methods through publications, presentations, workshops and debates.
