Tardigrades Survive Space, Radiation, and the Vacuum - But Not This
Tardigrades are known as some of the toughest creatures on Earth, surviving extreme radiation, freezing temperatures, and even the vacuum of space. These microscopic survivors can enter a state called cryptobiosis, allowing them to endure conditions that would kill almost anything else. But surprisingly, there are still limits to what they can handle. Certain extreme conditions can break even their incredible defenses. Watch now to discover what can actually defeat these nearly indestructible organisms.Credit:
