Scientists are digging up Adélie penguin guano to study millennia of Antarctica’s history.
Tiny slivers of plastic are making it all the way into humans’ guts and into their feces, a new study shows.
Coal analysis suggests that plant-eating dinosaurs, by walking kilometers between their picnic areas and their toilets, distributed important nutrients widely and boosted ecosystem health.
Nitrogen isotopes within samples of bat excrement accurately reflect modern precipitation patterns. So could guano serve as a paleoclimate record?
Researchers working in caves in Borneo and elsewhere are finding evidence that biological processes shape many tropical caves by slowly eating away at surrounding rock.
