Tardigrades Can Survive Almost Anything—Scientists Are Learning Why
Tardigrades survive conditions that would kill any other creature. Scientists are decoding their secrets for potential applications in medicine and space exploration.

Tardigrades, also known as water bears, can survive conditions that would instantly kill any other animal: the vacuum of space, extreme radiation, temperatures near absolute zero, and pressures six times greater than the deepest ocean trenches.

Survival Mechanisms

When faced with harsh conditions, tardigrades enter a state called cryptobiosis, expelling almost all water from their bodies and essentially hitting "pause" on their metabolism. They produce special proteins that protect their cells from damage.

Applications for Science

Scientists are studying tardigrade proteins for potential applications in medicine and biotechnology. These molecules might help preserve vaccines without refrigeration, protect crops from drought, or shield astronauts from radiation.

Tardigrades have even survived being shot from a gun at high speeds, leading some researchers to speculate they could theoretically survive an interplanetary journey on meteorites.
