●Making progress with limb models. Denis Duboule, Nature 1 August (2002)News and Views article, which describes new work that challenges the 'progress zone' model of limb development. It proposes instead that all of the various cell types to form a limb are specified at the same time, early in development, and that they expand at different times afterwards to form the complete limb.

●Viruses and interferon: a fight for supremacy Michael G. Katze, Yupeng He and Michael Gale, Jr Nature Reviews Immunology September (2002). Interferons are produced by host cells in response to viruses; viruses, in turn, have mechanisms to counteract these responses. This review article discusses current understanding of the complex network of cellular antiviral processes.
