Joe, God put that lake their specifically to test your faith. Isn't he mysterious??

This is really, really cool though I wish more people expected it. Finding bacteria in salt water should really not be a big deal. We know about halophiles, we've found bacteria living in solid rock. These guys find all kinds of places to live.

Can a microbe go crazy?

I don’t mean that a microbe will suddenly think he’s Napoelon, but do microbes ever just get fed up with their colonies and leave?

Well, they can form spores and attempt to send their genetic material to another location, just like plant seeds or even pollen, some even form extremely basic pseudo-multi-cellular structures. In short, bacteria do amazing shit we often couldn't imagine, and when we find it we should be both awed and simply reassured. Every little trick they use to survive gives us a hint at a trick our line used to survive.

Blood Falls? Blood Falls?!

Just once, I'd like to hear some news out of Antarctica that didn't immediately bring to mind At the Mountains of Madness.

This is going to end badly for everyone.

Antarctica and Greenland are the future of mineral claims.

Greenland is undisputedly Denmark's. But Antarctica is up for grabs, and there will be wars fought for its control unless we get smart and start using our words for negotiation instead of our weapons for killing.

Just to add if we don't get smart and talk things out, there are other little things almost waiting for us to mess this world up. Live will survive. Humans probably will not.

I was talking about this with my significant other last night. My plan is to use this as an argument against the global warming deniers out there: "No global warming?! Dude, the glaciers are BLEEDING now!"

That's more than a reasonable warning. We know bacteria can survive trapped in ice, and we are regularly shocked by just how long. "Keep the unknowns frozen in solid of ice." That's a slogan I can support.

Whoa whoa whoa waitaminute.

These microbes have been living in a closed system with no energy coming in from outside — no sunlight, no geothermal vents, no dead whales, no nothing — for 1.5 million years?

Screw evolution. This shit is here to test our faith in the laws of thermodynamics.

No. Not nothing at all. They evolved to get energy from the sources around them, that happens to be things we may not have considered as energy sources in the past.

Also, did Discover just dramatically change the text and layout of this entry or is that just me?

nebulawindphone: From reading the linked articles it appears that the closed system contained enough organic matter for the bacteria to very slowly eat it, using iron from the surrounding rocks (via a bunch of sulphates) instead of oxygen.

So it's a closed system that hasn't run down yet.

This reminds me of the Berkeley Pit, which also contains unique microbes.

Strangely, this may not be all bad. According to Wikipedia:

New fungal and bacterial species have been found to have adapted to the harsh conditions inside the pit. Intense competition for the limited resources caused these species to evolve the production of highly toxic compounds to improve survivability; natural products such as Berkeleydione, berkeleytrione [3] and Berkeley acid [4] have been isolated from these organisms which show selective activity against cancer cell lines.

So not only are the mutant bacteria capable of eating sulfur, iron, and carbon, they also appear to be capable of picking terrifyingly appropriate Metafilter usernames and posting threats. I guess a couple of million years under the ice must be more than enough time to develop a horrible immortal sentience before gushing out of the earth in rivers of blood.

If I favorite your comments, will you promise to eat me last?

Totally. Those bacteria and viruses are incredibly tenacious creatures. It really gives one the feeling that, if life evolved on some other planet like Mars, that life might still be there. It could just be buried in some really hard to reach place.

There's a history of four billion years of increasingly complex life on this planet, about one-third the age of the universe. That seems like a long term to me.

I was wondering the same thing, and from the Ars Technica article, they imply that the bacteria live on a process of binding sulfur to iron, and are thus dependent on a slow flow of both. This is very low-energy, and the scientists think that the time-to-replication must be on the order of 300 days, rather than the 20 minutes for well-fed bacteria.

They're hanging on down there, but 'hardscrabble existence' barely begins to describe it.

Keynes: "In the long term, we're all dead." So, Flunkie's right.

That only works if you consider your individual life as all life. But it isn't all life, it's merely a blip on a continuous timeline of life. The timeline shows life becoming more organized as it progresses.

Indeed, the universe on the whole is becoming more organized: the smear of matter has coalesced into stars and planets and proteins, and those coalesced into viral and bacterial life, and bacteria began forming complex colonies: the first time matter organized for the greater social good. And so on through the first cells, and multiple cells, and then cells specialization, and next thing you know we're swinging through the trees.

From one angle — that of looking at inanimate matter — perhaps the universe becomes more disordered. From another angle — animate matter — it has overall become more organized. Maybe the fate of the universe hangs in the balance. :-)

That's only true if you exclude bacteria and other life forms from "we". I hang with dudes.
posted by msalt at 12:00 AM on April 19, 2009

When did I ever mention "we"? I said that life drives toward increasing organization. It does: over the span of something of the order of 14 billion years, life has gone from simple virii and bacteria to complex organisms that are now trying to design new life. That your body will die and rot to chaos is irrelevent to that.

Keynes said "in the long run WE are all dead". You replied "only if you consider your individual life as all life". It's not a royal we.

I dunno. I think life drives to increasing to the minimum complexity needed to live, given a plentiful source of free energy (such as the sun), and provided it's given the chance to adopt and evolve. If not given that chance it dies, and pretty easily. And that chance and free energy, cosmically speaking, are absent in many more places than they are present.

In other words, life generally drives to end.

If we don't nuke ourselves first, I imagine we're going to expand to other worlds. Once that process begins, what's to stop us from become common throughout the universe (given enough time)?

Other than, say, the eventual occurrence of proton decay or the like. But that's 10¹⁰⁰ years away, so perhaps we'll have mastered the energy-matter duality and can make our own protons. Or we'll have evolved to become intelligent blue.

Or made our own new universe and escaped down a giant rabbit hole. ;-)

But when you consider life as a totality, it really does get more and more complex with time, like five fresh fish said. Most creatures only adapt to a point , but then there's us. Humans keep reducing the local entropy at an ever increasing rate, in a way that other animals don't. Trap bacteria in a salty lake and they learn to adapt, reaching a local equilibrium with their surroundings. Trap humans in a similar situation, and assuming we didn't die right away one of two possible outcomes would happen: the people would exhaust the resources of their watery prison and eventually die through too much growth, or they'd find a way to break out and expand into new territories. We just don't do equilibrium.
