Health officials report the first case Ebola virus disease outside of Guinea, Liberia, and Sierra Leone. A 40-year-old man from Nigeria has died.
Gustafson et al report in the 29 June Nature that a marine ciliate, Mesodinium rubrum, steals organelles from ingested algae (Nature 2000, 405:1049-1052). Although M. rubrum does not appear to ingest other food, or to maintain permanent symbionts, the ingested organelles help the ciliate to keep photosynthesizing and to maintain a high level of cell division.
