Though it is a pleasure to write a short foreword to this collection of excellent scientific papers covering a range of biological topics, the rather depressing feature is the small number of papers. All-electronic publishing is developing and your Editors do have great faith in it. One problem for potential authors has been the reluctance of the abstracting journals to pay any attention to electronic journals - perhaps Springer should make a rapid move in this area and start the first all-electronic journal abstracting this type of literature. However, even the paper citation journals are starting to pay attention to the medium. The particular advantages of all-electronic publishing are beginning to emerge more clearly and it is clear that publishing video material is a unique advantage of our format. Several papers took advantage of this - for example those by Riehle and others on cell behaviour in tunnels, by Bereiter-Hahn and Voss on zonation in the plasmalemma and by Pavlikova, Zicha, Chaloupkova and Vesely on cell motility of tumour cells. These papers made essential and extensive use of video material, publishing some material of great originality. The work on cell pola rity and calcium ions in Fucus embryos by Brownlee, Manison and Anning used animation to present their results in an especially clear way. The facility of use of animation is another special advantage of our type of publication that should be more widely used.
