Revived Microbe May Hold Clues For ET Lifeforms

krou writes "Science Daily is reporting that a microbe, Herminiimonas glaciei, buried some 3 km under glacial ice in Greenland, and believed to have been frozen for some 120,000 years, has been brought back to life (abstract). The microbe, some ten to fifty times smaller than E. coli, was brought back over several months by slowly incubating it at gradually increasing temperatures. After 11.5 months, the microbe began to replicate. Scientists believe that it could help us understand how life may exist on other planets. Dr. Jennifer Loveland-Curtze, who headed up the team of scientists from Pennsylvania State University, said: 'These extremely cold environments are the best analogues of possible extraterrestrial habitats. ... [S]tudying these bacteria can provide insights into how cells can survive and even grow under extremely harsh conditions, such as temperatures down to -56C, little oxygen, low nutrients, high pressure and limited space.' She also added that it 'isn't a pathogen and is not harmful to humans, but it can pass through a 0.2 micron filter, which is the filter pore size commonly used in sterilization of fluids in laboratories and hospitals. If there are other ultra-small bacteria that are pathogens, then they could be present in solutions presumed to be sterile. In a clear solution very tiny cells might grow but not create the density sufficient to make the solution cloudy.'"

Great! Glacier water...

[PoolOfThought]

Now bottled water from glaciers is suspect. I feel for these folks:

From the second one:
"Glacier water is superior to common water sources, because it is not filtered through the ground where a variety of dissolved solids and organic particles such as rocks, sand, metals, chemicals and underground pollutants can attach to each water molecule. It is essentially an exclusive worry-free water source â" clear of heavy chemicals, drug residues, jet fuel, toxins, dust particulates, etc. â" unlocked from glaciers that are over 10,000 years old. Not only will our clients be able to drink and bathe in this premium untainted water, they can also breathe indoor air that is hydrated or humidified with pollution-free water."
