Dogs living near the site of the Chernobyl nuclear disaster have mutated to develop a new superpower - they are immune to radiation, heavy metals and pollution. Scientists collected blood samples from 116 stray dogs living in the Chernobyl Exclusion Zone (CEZ), finding two different populations that were both genetically distinct from other dogs in the surrounding area.

This suggests they have adapted to withstand long-term exposure to this toxic environment and would explain why they have continued to thrive in the wasteland. Understanding how the dogs developed their genetic superpower could help better understand the health impacts of living in a highly toxic environment with multiple environmental hazards, not just in dogs but also in humans.
