Indestructible Tardigrades: Nature's Survivors

Did you know tardigrades are basically indestructible microscopic creatures that can survive the vacuum of space

without any protection. These tiny water bears can withstand temperatures from near absolute zero

to boiling, handle radiation a thousand times stronger than what would kill us,

and live without food or water for decades. Scientists sent them to space and

they came back alive. They enter a state called cryptobiosis where they dry out and shut down all

metabolic processes, becoming practically immortal until conditions improve.
