Iron-eating Bug Found to Thrive in 121C Heat

shobadobs writes "A story in the Independent reports that a microorganism appropriately referred to as 'Strain 121' has been found capable of thriving, with its colony size doubling, at a heat of 121 degrees Celsius, eight degrees more than the previously recorded maximum temperature that an organism can survive. This deep-sea volcanic vent creature was found on the bottom of the Pacific Ocean, and it feeds off of iron." Luckily it's only a microorganism. At first glance I thought scientists might have discovered a real-life rust monster.

Welcome

[Phroggy]

I, for one, welcome our new iron-eating overlords.

LOL, I love that quote.

Seriously though, the organism doesn't just chew through iron like a termite through wood. It only feeds off microscopic (smaller than itself) pieces of iron, such as wandering particles/shavings. Even if it were able to eat through an iron surface, its' small size would prevent it from doing much immediate damage.

Could you make yourself useful and round up humans to toil in their underground.... errr... iron mines...? Hey! That joke finally works!

By the magic of Google, I think it's Brockman of The Simpsons:

"Ladies and gentlemen, uh, we've just lost the picture, but what we've seen speaks for itself. The Corvair spacecraft has apparently been taken over- 'conquered' if you will- by a master race of giant space ants. It's difficult to tell from this vantage point whether they will consume the captive Earthman or merely enslave them. One thing is for certain: there is no stopping them; the ants will soon be here. And I, for one, welcome our new insect overlords. I'd like to remind them as a trusted TV personality, I can be helpful in rounding up others to toil in their underground sugar caves." (Deep Space Homer)

No idea about IN SOVIET RUSSIA though mate.

Depth vs. Temperature?

[Fesh]

I would guess that the only place these bugs could exist would be where the pressure is high enough to keep water liquid at a temperature that is 20 degrees C above boiling (at sea level)... Is the temperature a prerequisite for their metabolic processes?

What about hot bugs?

[tiled_rainbows]

I read about this in the paper on the way to work. And the article ended, yet again, saying "this is encouraging for people who still hope to find life on Mars". I understand that extremophile microbes demonstrate that our conception of a life-supporting environment has heretofore been a little narrow, but recent discoveries keep turning up organisms that live in hot, high-pressure envirtonments, kind of the exact opposite of the conditions on Mars. So how does this help the Martian life lobby? Given these recent findings, wouldn't we be better off looking for monocellular life somewhere like Venus, say?

Fear my Aluminium Suit.

[Channard]

Hah! How those fools laughed when I made my aluminium hat and bacofoil suit to block out the CIA's space-rays. Yet I alone will be safe from the iron eating scourge while those naysayers struggle to hold their trousers up as their belts are eaten away by the iron-devouring scourge.

Only possible in the deep sea

[asciimonster]

Since this is, I presume, a water-based organism, it can only survive such high temperatures deep down in the ocean. At sealevel, the water inside the organism will boil and make the thing explode. Also I wonder how it can keep it's aminoacids and DNA intact. At 120 degrees C there is enough energy to break the Hydrogen bonds which give the proteines and DNA it's stability...

Could somebody give me some indications on the pressures sown there?

How sex

[vevva]

Colonies doubling in size at 121C.

Now that's what I call hot sex.

Of course....

[CowsAnonymous]

There is an animal that can probably live past all these creatures in extreme conditions, and that's the Waterbear

From this article... The waterbear can revert to an "instant coffee"-dry state which resists storage in liquid nitrogen, contact with mineral acids, organic solvents, radioactive radiation and boiling water. After this kind of brute "scientific" scrutiny the miraculous creature is still able to return to normal life--it needs only a small droplet of water!

Immediate Scientific / Technological Impact: PCR

[tm2b]

The discovery of new extremophiles is very important to biotech.

A discussion of the various discoveries from extremophiles is here. I'm going to focus on one process, made possible by genes from hyperthermophiles from deep ocean vents. One process, PCR (Polymer Chain Reaction), the technology that allows us to create large batches of identical DNA, depends upon polymerase taken from these organisms.

The reason is this: in order to for PCR to work, a solution of polymerase and the desired DNA sequence is heated so that the DNA will quickly uncoil, allowing the polymerase to go to work - copying each strand of DNA present, doubling the amount of DNA. The solution is cooled, and then the process repeats, doubling the amount of DNA each time. Unfortunately, "normal" polymerase quickly breaks down at the best temperatures for this process.

Extremophile polymerase changes all of this, since it's perfectly happy to operate at these high temperatures.

That's not a bug, that's a feature

Ferrous Calciferous Lithium or (FeCaL(i)) Matter is what is produced.

Lucky?

[RealSalmon]

Luckily it's only a microorganism.

Whew! It's only a microorganism . . . they're only responsible for more deaths than everything else on the planet combined.

Remember . . . it's usually the little stuff that gets you.

It was really only one joke

[donscarletti]

I believe there was only one joke actually by Yakov Smirnoff, that was:

In America you can always find a party, in Soviet Russia party can always find you

an extremely witty joke by almost everyone's standards, making a great pun with the word "party" to create truly a beautiful and lasting joke.

The classic joke was later reused in the cartoon Family Guy as the Yakoff Smirnoff setting of the autodrive system. The voice made comments like "you are coming to a fork in road, in soviet russia, road fork you!" and "in soviet russia, car drive you" to succesfully create riotous amusement by the shear lameness of the repitition.

Unfortunantly lameness and repititon are also the chosen methods of expression on another media: the internet. This continuation of the running joke has made the memory of that great joke lost in a sea of "in soviet russia, opteron makes beowolf cluster out of you!" travesties.

But it seems in this corrupt world, anything innocent and beautiful will eventally be raped by those who have nothing to do but distroy purity.
