“Not all cells are ‘dead’ when an organism dies,” senior author Peter Noble of the University of Washington and Alabama State University told Seeker. “Different cell types have different life spans, generation times and resilience to extreme stress.”
In fact, some cells seem to fight to live after the organism has died.
“It is likely that some cells remain alive and are attempting to repair themselves, specifically stem cells,” Noble said. Link: Read Complete Article
