The BMJ, BMJ Open, Heart, Thorax, and Tobacco control – all journals in BMJ’s stable, have announced they will no longer carry research funded in part, or in whole, by the tobacco industry. Fiona Godlee, BMJ Editor in chief, explains what that means, and Allen Brandt, professor of the history of science at Harvard University, gives us a potted history of the way in which the tobacco industry has manipulated science.

Also this week, Sebastian Brandner, professor of neuropathology at UCL, explains his research into the population prevalence of the prion which causes vCJD.
