Telomeres were like metal tips on the ends of DNA zippers. They kept the long strands from getting fouled up during the unzipping and re-zipping process at the core of cellular reproduction. When telomeres malfunctioned, people got cancer. When they wore down, people aged. By keeping telomeres in pristine condition, Eos—the name of both their product and their company—would act like the elixir of immortality.
