A bug that has lain dormant for over 120,000 years has been revived by Dr Jennifer Loveland-Curtze and a team of scientists from the Department of Biochemistry and Molecular Biology at Pennsylvania State University.
The Story in Brief
Scientists who want to go bug hunting in space practice by searching out dormant bacteria on earth and reviving them for research.
The latest bug, a tiny brown-purple microbe was discovered when a Gram-negative 1 ultramicrobacterium was isolated from a 120,000-year-old Greenland glacier ice core recovered from a depth of 3,042 metres (3.042 kilometres).
Dubbed Herminiimonas glaciei, the pigmentation of the original colony was brown-purple but after recultivation the colonies were translucent white to tan coloured. It took almost 12 months for the team to revive the microbe (designated strain UMB49T) by gently warming it in an incubator at 2%C for seven months and then at 5%C for a further four and a half months .
The H. glaciei microbe is tiny – ten to 50 times smaller than E. coli (which is also Gram-negative 1). Experts say its small size probably helped it to survive in the liquid veins among the ice crystals.
Dr Loveland-Curtze says that other microorganisms could exist on other worlds and studying Microbes found in extreme conditions on Earth may provide insight into what sorts of life forms could survive elsewhere in the solar system.
More details are available at the International Journal of Systematic and Evolutionary Microbiology and it was reported in the Scientific American in June 2009.
Stranger Danger
While the newly discovered bug and its revival has excited scientists who believe it raises hopes that dormant life might be revived including bugs found on planets such as Mars none of the reports this writer has read so far discussed the danger inherent in reviving long dormant bacterium.
Whether or not this particular Gram-negative ultramicrobacterium is dangerous to humans (there was no mention of this in the scientific report) it does raise the question; is it safe to uncover such bacteria either from the depths of the earth or from extraterrestrial planets?
There is the possibility that scientists may discover or “recover” DNA molecules that could have very beneficial uses but if one is discovered that is lethal to humans or plant and animal life would governments or terrorist groups be tempted to cultivate it for use as a deadly “weapon”
One could make the argument that it is better to discover a potential threat before it becomes a threat so that scientists have time to examine it and develop an antidote to it. But can scientists be trusted to keep it secure. There have been instances including the recent escape from a laboratory in Australia of the horse flu virus that caused havoc in that industry.
Of course, human curiosity is not the only way that extraterrestrial bacteria from Mars or elsewhere make their way to earth, for example there are 12 Martian meteors known to exist on earth, collectively called Shergotty-Nakhla-Chassingy or SNC (“snick”) meteorites. The most famous Martian meteor is called Allan Hills 84001 (ALH 84001) and is believed to have blasted off Mars 16 million years ago, hitting Earth 13,000 years ago in Antarctica. It appears to hold microscopic fossils of Maritain bacteria which sparked intense debate about whether ancient life ever existed on Mars.
Some people postulate that “life” may have “arrived” on earth aboard such meteorites which could lead one to hypothesis that the “killer” bug that wipes out mankind may also arrive the same way ….or be brought back to earth by an unsuspecting team of scientists? Maybe it is already here but lying dormant possibly after wiping out life as it was in a previous millennium?
Shadow in the Flame believes that the issue of reviving dormant microbes, viruses or bacteria or bringing them back to earth for investigation is too important to be left to curious scientists to decide especially as their rise to the top of the scientific ladder of recognition often depends on making ground breaking “discoveries”.
It is the mark of a good scientist to be curious and we want and expect them to be excited by challenges and new discoveries. But is earth the only place to carry out this type of scientific research. Indeed is it the right place. This may be exactly the type of work that should either be done on a space station or on the moon.
Many governments have been looking for a good excuse to go back to the moon. Maybe they should consider building a secure research laboratory there to carry out this type of potentially dangerous research.
What do you think?
1 According to Wikipedia Gram-negative bacteria are those bacteria that do not retain crystal violet dye in the Gram staining protocol.
Many species of Gram-negative bacteria are pathogenic, meaning that they can cause disease in a host organism. This pathogenic capability is usually associated with certain components of Gram-negative cell walls, in particular the lipopolysaccharide (also known as LPS) layer. In humans, LPS triggers an innate immune response characterized by cytokine production and immune system activation. Inflammation is a common result of cytokine production, which can also produce host toxicity.

Interesting post, thanks. I have a question – will there be a continuation?
Editor’s note:
I think that the latest story, Confronting the Future is a continuation of this theme. It also deals with scientists going where others have feared to tread without concern for the philosophical issues.

Ясность мысли способствует ясности изложения. Можете тоже самое объяснить для самых-самых блондинок?

The clarity of thought contributes to the clarity of the account. Can explain it more simply for the very – very blonds?
Editor:
HaHa. I once had the most beautiful blond apply for the job as my secretary. My office manager said I would be crazy to hire her as everyone knows blonds are dumb and the better looking they are the dumber they are. And she (the office manager) was a girl.
But out of 10 or more applicants I interviewed, she seemed by far the best one for the job. I agonised over it as the office manager was strongly against hiring her and to make matters worse, all the men in the office were totally for her. I thought that might be a problem but it would be up to her to handle it, so I hired her.
She had a wonderful smile, a great personality and she was keen to do well in the job. Yes, I admit, like everyone else I was attracted to her but I have never gone out with staff, it only causes problems down the track if / when you break up.
With all the attention from the men and the agro from the office manager, she got off to a shaky start and I almost terminated her after a month. I told her that because she was pretty and blond everyone expected her to fail in business, but she looked me in the face and said “I will not fail” with such conviction, I could not fire her.
A couple of weeks later, the office manager’s husband had a bad accident and she had to leave work immediately. We thought she was coming back later but she couldn’t and didn’t return for almost a month. Michelle, the blond, stepped in to her job without being asked and without ever seeking any praise from anyone. She taught herself on the job, rang the office manager only when absolutely necessary and worked like a slave to get the work done.
She handled angry wives whose husbands were working too much, gave advice to the new staff, never looked frazzled and always had a smile for anyone who needed it. When the office manager came back, she could not believe that her work was up to date and well done. A few weeks later, she resigned to take an easier job closer to home. Her recommendation for a replacement – Don’t waste your money advertising, give it to Michelle.
She was with us for 3 or 4 years and by the time she left she was regarded by all including clients, suppliers, and staff as the most efficient, wonderful person in the company. It was an honour to work with her and I hope Michelle, wherever you are, you are happy and well. You changed our view of blonds forever.
Nice information, many thanks to the author. It really is incomprehensible if you ask me now, playing with general, the usefulness and significance has me overwhelmed. Thank you and good luck!
EXACTLY what I’ve been looking for! Thanks so much!

All men delusion, but not equally. Those who day-dream by means of night in the dusty recesses of their minds, wake in the heyday to find that it was swell-headedness: but the dreamers of the day are rickety men, because they may act on their dreams with problematic eyes, to create them possible.
