For clarification: Half-life of atoms as in "radioactive decay" (weak, strong and EM force) cannot really be modified by perservations methods. Here [0] a precise answer. The decay-time of bio-molecular strucutres/bonds (containing information like DNA) can be modified in many ways very easily: low temperatures, exclusion of oxygen (amber) ... I guess "half-life" of DNA is just some fast and crude laboratory proxy for chemical "stability" in a specific setting.
