Mutant wolves roaming the deserted streets of Chernobyl appear to have developed resistance to cancer - raising hopes the findings can help scientists fight the disease in humans. The area has remained eerily abandoned ever since, with the Chernobyl Exclusion Zone (CEZ) put in place to prevent people from entering a 1,000-square-mile area where the radiation still poses a cancer risk. Dr Cara Love, an evolutionary biologist and ecotoxicologist at Princeton University in the US, has been studying how the Chernobyl wolves survive despite generations of exposure to radioactive particles. Dr Love and a team of researchers visited the CEZ in 2014 and put radio collars on the wolves so that their movements could be monitored. She said the collars give the team "real-time measurements of where [the wolves] are and how much [radiation] they are exposed to".
