Extremophiles: Noxious & Loving It
There was a highly compelling rumor orbiting the biosphere at the beginning of December that NASA had finally discovered verifiable alien life.
It was not clear in aggregators like The Huffington Post whether it was on our moon, or one of Jupiter’s, or in some yet unnamed neighboring galaxy. An embargo on the academic paper only added to the hype and excitement. But when the lunar dust settled, it turns out it was just another strand of unsubstantiated viral gossip, or as we liked to say in the good old days before the interweb, bullshit.
The truth was, NASA-funded researchers were hard at work at Mono Lake in California experimenting successfully with a new breed of microorganism— a bacterium– to be accurate, that can survive entirely in arsenic. Yes, arsenic.
You thought those freaky chemosynthesis-dependent tubeworms living 5000 feet underwater next to volcanic thermal vents were tough? This newfound life form, fondly known as GFAJ-1, would outlive a tubeworm any month of the year. It doesn’t just find a way to live in an unpleasant area; it literally incorporates pure poison into its being and flourishes.
“The discovery will require some textbooks to be rewritten.” Says one scientist who’s read enough textbooks to know. I found one from 1988 that says there are six fundamental elements making up the key components of all cells strands (i.e. DNA): carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus. Phosphorus is particularly essential. No living thing can exist without it… till now.
Suddenly, one tiny microbial badass has figured out a way to substitute phosphorous for arsenic and not just survive, but thrive. In just six days, the bacterium multiplied twenty-fold as it wolfed down the pernicious element, belched, and came back for more.
“As someone who regularly gives lectures in which I state, ‘every living thing uses phosphorus to build its DNA,’ the idea that I’m sitting here today discussing the possibility that that’s not true is… shocking.” Exclaims Felicia Wolfe-Simon. “Maybe we’ll be able to find E.T. now because we’ve got more information about what we might be looking for.”
Felicia and a merry crew of astrobiologists at Arizona State were searching for implications on how life can survive on planets like Mars and Venus. But the discovery seems more relevant in relation to how rapidly we’re toxifying our own blue-green planet. What a relief to know that evolution has already begun adaption/mutation in preparation for our acid rain filled future. Makes you want to pump a few more kids out immediately, don’t it?
I, for one, am relieved to know that after the smoke clears from the burning of every last gallon of fossil fuel, we can recklessly extract from the earth, and the chemical processing of the very last chopped down tree, that we’ll be okay living in an atmosphere comprised mainly of arsenic and it’s sister poisons. That’s the real implication of this discovery. On the macrobiotic level, we’re learning to survive in poison.
So don’t sweat recycling, or alternative energy, or any other attempt to reduce your footprint, because evolution is already taking care of it for us. That’s what evolution does when it sees shit going sideways. Our ingenious cellular machinery of lipids, proteins and enzymes is hard at work incorporating not just arsenic, but every other vile bi-product we’ve manufactured into the very core of our molecular being, so that we can stay on course in bringing hell to earth as we know it, and hopefully without commercial interruption.
Happy shopping season!
