The article is great in giving no scientific context and not even linking to a reference. I assume they talk about Dsup (https://en.m.wikipedia.org/wiki/Dsup https://en.m.wikipedia.org/wiki/Dsup), an enzyme preventing DNA breaks by stabilization. DNA breaks are caused by radiation and are what causes mutations (increased cancer risk) and in the extreme case cell death.
