As do all vital and flourishing enterprises, Artificial Life is evolving. This note is to inform our readers about new developments at the journal. The overall effect of these changes is to make Artificial Life more effective as the primary vehicle for the dissemination of original research in artificial life. The most recent Artificial Life conference demonstrated the vitality of the scientific (and artistic!) activities involving artificial life, with new energy being directed toward assessing our accomplishments anew and clarifying our fundamental open problems. Work in artificial life is noticeably more mature and connected with empirical data from nature. It is spreading into further disciplines and being assimilated into mainstream science. Our goal is to have the Artificial Life journal play an active leadership role in these trends, encouraging and supporting the continual growth and evolution of the study of life in all its possible forms. To achieve this goal we are contemplating various new features for the journal, such as soliciting more reviews of subfields and publishing news and announcements. We encourage your suggestions and comments about how the journal can better achieve our goal. Our most dramatic news is that during the summer of 2000 Christopher Langton decided to step down as Editor, to follow new career directions. We are sure that all of the readers of the journal will join us in giving Chris hearty and warm thanks for his service both to the field in general and to the journal in particular. The existence and success of each testify more to Chris’s vision and hard work than to any other single factor. He has been an inspiration for many of us. We are pleased that Chris will remain on the journal’s masthead as Founding Editor. You will notice some other changes on the masthead, due to changes in people’s careers. Hiroaki Kitano is stepping down as an Editor since his current work has moved too far afield from artificial life, and several people who are no longer active in the field have left the Editorial Board. We thank them all for their service through the journal’s birth and first few years. As a more mature journal, we no longer feel the need for an Advisory Board. We are grateful to the former Advisory Board members for their good service while the journal was getting started. Artificial Life’s editorial structure has been revitalized with a number of new people and new roles. Mark Bedau, a member of the journal’s Editorial Board since its inception, has joined Charles Taylor as an Editor. Mark has been actively involved in running the journal since Chris announced his intention to step down as Editor. We have also renewed and expanded the Editorial Board with the addition of over a dozen new members: Christoph Adami, Lee Altenberg, Wolfgang Banzhaf, Marco Dorigo, Doyne Farmer, Dario Floreano, Inman Harvey, Takashi Ikegami, Simon Kirby, Richard Lenski, John McCaskill, Barry McMullin, Norman Packard, Domenico Parisi, Rolf Pfeifer, Jordon Pollack, and Craig Reynolds. With these well-known pillars of the artificial life community on the Editorial Board, the journal will rest on an even stronger scientific foundation and better reflect the important active directions of artificial life research today. We also want to notify everyone about the formation of a professional organization
