Sense About Science is an independent charitable trust. We respond to the misrepresentation of science and scientific evidence on issues that matter to society, from scares about plastic bottles, fluoride and the MMR vaccine to controversies about genetic modification, stem cell research and radiation. We work with scientists and civic groups to promote evidence and scientific reasoning in public discussion.
