     * can survive massive doses of ionizing radiation (up to 5,000 Grays)—roughly 1,000 times the lethal threshold for humans     * can survive massive doses of ionizing radiation (up to 5,000 Grays)—roughly 1,000 times the lethal threshold for humans
     * they achieve this through extreme upregulation of specialized DNA repair genes and unique, tardigrade-specific DNA-protecting proteins like TDR1 that stitch their shattered genomes back together     * they achieve this through extreme upregulation of specialized DNA repair genes and unique, tardigrade-specific DNA-protecting proteins like TDR1 that stitch their shattered genomes back together
 +    * cryptobiosis (The Tun State): by drying out into an inactive state called a "tun," tardigrades slow their metabolism entirely, making them nearly impenetrable to external stressors like radiation, pressure, and the vacuum of space
