All sporadic cancer is caused by acquired somatic mutations (mutations that take place within cells of the body that are not passed down/inherited). Mutations often occur by incorrect repair of DNA damage by impaired DNA pathways such as the nucleotide excision repair (NER) pathway and the DNA mismatch repair (MMR) pathway.

The natural world is under threat from many anthropogenic sources, such as the spread of harmful invasive species and the decline of native populations due to habitat loss and climate change. Finding new technologies and methods to assess and tackle these increasingly global problems is crucial. However, in order to tackle big problems, sometimes you need small solutions. One such emerging tiny tool is the sequencing of environmental DNA (eDNA)!
