Microscopic animals that endure the harshest conditions are giving up their secrets. Tardigrades survive drying, freezing, and radiation by entering a glass-like dormant state. Their proteins hint at ways to protect biological material.
Extreme survival
The feats are startling. Tardigrades withstand vacuum and radiation. Few organisms compare.
Vitrification
The trick is glassy. Special proteins turn the cell interior to a stable glass. Damage is prevented.
Unique proteins
Molecules are key. Tardigrade-specific proteins shield structures. They are being studied.
Preservation uses
Applications loom. The proteins could stabilize vaccines or cells. Storage may improve.
Radiation defense
Repair is robust. The animals fix DNA damage efficiently. Mechanisms intrigue.
Ongoing study
Interest grows. Their biology inspires new methods. Research continues.
The bottom line
Tardigrades survive drying, freezing, and radiation by vitrifying their interiors with special proteins. Those molecules could stabilize vaccines and cells. Their extreme biology is under active study.
