Tardigrades can withstand 1,000 times more radiation than other animals, [17] median lethal doses of 5,000 Gy (of gamma rays) and 6,200 Gy (of heavy ions) in hydrated animals (5 to 10 Gy could be fatal to a human). [18] Earlier experiments attributed this to their lowered water content, providing fewer reactants for ionizing radiation. [18]
Chinese military scientists believe the tardigrade’s cells improve a human's ability to withstand radiation and potentially other diseases.
Tardigrades are affectionately known as water bears or moss piglets and are tiny invertebrates measuring a maximum of 0.05 inches in length. Viewed through a microscope, they look a little like a ...
Tardigrade anatomy [3]. Tardigrades have a short plump body with four pairs of hollow unjointed legs. Most range from 0.1 to 0.5 mm (0.004 to 0.02 in) in length, although the largest species may reach 1.3 mm (0.051 in).
Tardigrades, or water bears, thrive in some of Earth’s harshest environments. Now, researchers say they have unlocked the survival mechanism of the tiny creature. Scientists now think they know ...
Dsup (contraction of damage suppressor) is a DNA-associating protein, unique to the tardigrade, [1] that suppresses the occurrence of DNA breaks by radiation. [2] [3] When human HEK293 cells were engineered with Dsup proteins, they showed approximately 40% more tolerance against X-ray radiation.

Tardigrades live over the entire world, including the high Himalayas. [4] Tardigrades are also able to survive temperatures of close to absolute zero (−273 °C or −459 °F), [5] temperatures as high as 151 °C (304 °F), radiation that would kill other animals, [6] and almost a decade without water. [7]
