The study was published online this week on PLOS ONE.
In the tightly crowded burrows of the African naked mole-rats' world, carbon dioxide builds up to levels that would be toxic for other mammals, and the air becomes highly acidic. These animals freely tolerate these unpleasant conditions, says Thomas Park, professor of biological sciences at UIC and principal investigator of the study -- which may offer clues to relieving pain in other animals and humans.
Much of the lingering pain of an injury, for example, is caused by acidification of the injured tissue, Park said.
