Grauwolf nli User ID: 1387577 Germany 05/17/2011 08:34 PM Report Abusive Post Report Copyright Violation | seriously, wtf is that thing? Quoting: Anonymous Coward 983877[link to en.wikipedia.org] "Tardigrades have been known to withstand the following extremes while in this state: Temperature – tardigrades can survive being heated for a few minutes to 151 °C (424 K),[citation needed] or being chilled for days at -200 °C (73 K),[citation needed] or for a few minutes at -272 °C (~1 degree above absolute zero).[8] Pressure – they can withstand the extremely low pressure of a vacuum and also very high pressures, more than 1,200 times atmospheric pressure. Tardigrades can survive the vacuum of open space and solar radiation combined for at least 10 days.[8] They can also withstand pressure of 6,000 atmospheres, which is nearly six times the pressure of water in the deepest ocean trench.[9] Dehydration – tardigrades have been shown to survive nearly 10 years in a dry state.[16] When encountered by extremely low temperatures, their body composition goes from 85% water to only 3%. As water expands upon freezing, dehydration ensures the tardigrades do not get ripped apart by the freezing ice (as waterless tissues cannot freeze).[17] Radiation – tardigrades can withstand 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] The only explanation thus far for this ability is that their lowered water state provides fewer reactants for the ionizing radiation.[citation needed] In September 2007, a space launch (Foton-M3) showed that tardigrades can survive the extreme environment of outer space for 10 days. After being rehydrated back on Earth, over 68% of the subjects protected from high-energy UV radiation survived and many of these produced viable embryos, and a handful survived full exposure to solar radiation.[8] Environmental toxins – tardigrades can undergo chemobiosis—a cryptobiotic response to high levels of environmental toxins. However, these laboratory results have yet to be verified.[19][20]" |

Quoting: ComedianWon’t work, there to extreme... Then feed it a diet high in trans-fats. Whatever it takes, something that looks that weird needs to die. hes right...burn it. BURN EVERYTHING. especially the bananas. |

Quoting: Nature 1387651It prevailed over sub-zero temperatures, unrelenting solar winds and an oxygen-deprived space vacuum. see link for picture and more of the article: [link to www.bbc.co.uk] so the humans still think it ok to use other species in experimentation . we are so DOOMED. That little water bear did not sign up for it i'm sure |
