Elephants' Hot Testicles: A Potential Cancer Cure?

Elephants have a lower risk of developing cancer compared to humans, and researchers believe that their multiple copies of the p53 gene, which helps prevent DNA damage in cells, may be the reason. This gene provides extra protection to their sperm from hot temperatures, as elephants have their testicles located inside their bodies. The theory suggests that the extra copies of the p53 gene allow for multiple rounds of "copy-editing," reducing the risk of damaged cells surviving. Studying how elephants naturally circumvent cancer could provide insights into the disease.
