WHAT IS MIGHTIER THAN A COCKROACH
The deep-freeze bacteria could point to new methods of cryogenics, and they are the sort of biology scientists say might exist on Mars and other planets and moons.
The existence of microorganisms in these harsh environments suggests that we might one day discover similar life forms in the glaciers or permafrost of Mars or in the ice crust and oceans of Jupiter’s moon Europa,"
Other microbes have been discovered in similar frigid environments, sometimes clinging to pockets of liquid water in ice packs. And some microbes survive in ice as spores, but they need to be cultured to bring them to life.
NASA described the newfound critter as "the first fully described, validated species ever found alive in ancient ice."
"They immediately started swimming when the ice melted," and the cryopreserved bacteria were instantly ready to eat and multiply.
The creatures found might be able to survive in their suspended state for millions of years.
Just think about it millions of years.
Seen under a microscope, the live bacteria are stained green. Dead ones are red.
The Most Extreme Creatures.
Extremophilic microbes are a wild bunch. They can be found thriving in some of the most hostile environments imaginable – swimming in near-boiling water, eating rocks, lounging in sub-zero temperatures, and hanging out where radiation levels rival nuclear reactors.
They’re tougher than duct tape, boldly going where humans dare not and cannot.
Extremophiles are also a multimillion dollar-a-year business – some of them are employed to eat oil and help clean up spills. Others have important applications in medical research. But for many scientists, these hardy microbes are interesting because they suggest the potential for life on other planets.
Do you know what is Mightier than a cockroach?
Toxitolerant organisms can withstand high levels of damaging agents. They can be found swimming around in benzene saturated water or in the core of a nuclear reactor.
One species of bacteria, Deinococcus radiodurans, can withstand a 15,000 gray dose of radiation – 10 grays would kill a human and it takes over 1,000 grays to kill a cockroach. Extraterrestrial life forms would most likely need to possess similar tolerances to radiation, as the atmosphere on other planets, or lack thereof, filters out much less radiation than Earth’s.
