FIELD 01Tardigrades survive by making stress feel negotiable.
FIELD 02One of their stranger tools is Dsup, a protein named for damage suppression.
FIELD 03In experiments, Dsup reduced DNA damage when expressed outside the tardigrade that evolved it.
FIELD 04Later work connected the protein to chromatin binding and protection against hydroxyl radical damage.
FIELD 05It is not immortality. It is molecular armor placed near the genome.
Dsup makes DNA protection feel less like a metaphor and more like a protein surface.
