Detecting biological warfare research. A comparison of the number of publications from two Russian scientists. L. Sandakchiev (black bars) was involved, as the head of the Vector Institute for viral research, in the Soviet project to produce smallpox as an offensive biological weapon. V. Krylov (white bars) was not. Note the decrease in publications by Sandakchiev compared with those by Krylov. The data were compiled from citations from a PubMed search for the researchers on 15 August 2002.
