In the vast wetlands of Florida's Everglades, an ecological wound opened decades ago when Burmese pythons established themselves as unchallenged apex predators, quietly unraveling the native food web. Now, researchers have answered this slow-moving crisis with a strategy that turns the predator's own hunger against it — fitting opossums with GPS collars so that when a python strikes, it unknowingly swallows a beacon that guides its own capture. It is a reminder that in the long contest between human ingenuity and ecological disruption, the most effective tools are sometimes borrowed from natur
