Tardigrades, or water bears, are tiny aquatic creatures that can survive through incredible conditions including extraordinary high and low temperatures, vacuum and extremely high pressures, desiccation and intense radiation. Authors have decoded the entire genome of the tardigrade Ramazzottius varieornatus that is known to survive exposure to high doses of radiation. Using this full genome, authors found a new protein, Dsup (Damage Suppressor), that protects the DNA when it is irradiated even in the human cultured cells when the gene is transfected. The genomic data produced in this study could be a fundamental resource for medical, molecular and evolutional biology.
