The Cooperative View: MBL Scientists Give Evidence That Centrosomes Evolved Through Symbiogenesis

MBL, WOODS HOLE, MA—There are two ways in which cooperation is the theme of a paper published this week by Mark Alliegro and Mary Anne Alliegro, scientists at the Marine Biological Laboratory’s (MBL) Josephine Bay Paul Center.

One is revealed in the paper’s acknowledgements, where the Alliegros thank those who helped them after Hurricane Katrina completely disrupted their laboratory at Louisiana State University (LSU) in New Orleans – and their lives – in 2005... More>>>
