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]
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 ...
Tardigrades have been shown to respond to different temperature changes at different developmental stages. Specifically, the younger the egg, the less likely it is to survive extreme environments. However, not too long after development, tardigrades demonstrate a remarkable ability to withstand these conditions.
They have been known to survive in temperatures as low as -328°F and as high as 304°F as well as in toxic chemicals, radiation, boiling alcohol, and both low and high pressures. ... Tardigrades ...
Chinese military scientists believe the tardigrade’s cells improve a human's ability to withstand radiation and potentially other diseases.
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.
A spacecraft carrying tardigrades crashed on the moon in 2019. In a 2021 study, scientists set out to test whether the creatures could've survived.
