New Form of Life - December 3rd 2010, 01:33 AM

A bacterium found in the arsenic-filled waters of a Californian lake is poised to overturn scientists' understanding of the biochemistry of living organisms. The microbe seems to be able to replace phosphorus with arsenic in some of its basic cellular processes — suggesting the possibility of a biochemistry very different from the one we know, which could be used by organisms in past or present extreme environments on Earth, or even on other planets. http://www.nature.com/news/2010/1012....2010.645.html

Basically the main point is that arsenic is incorporated into the DNA and proteins. From what I know there is no previous evidence showing arsenic as a DNA building block. Not to mention the fact that arsenic is toxic for most multicellular organisms, not sure about bacteria.

I'm not a biochemistry expert by any means, but I do wonder if a bacterium with arsenic in its genetic DNA could prove to kill other multicellular organisms.

Good ol' Mono Lake.

I hope you don't mean it's middle finger
that's a bad'un.. :P

I read about this a few days ago, and I can't really say I'm surprised. It's just not logical to think that our way of life (i.e. carbon-based, anti-arsenic life) is the only way.

It was just a matter of time till they found these little buggers

It makes perfect sense Arsenic and Phosphorus are in the same group in the periodic table.

I never understood why so many scientists were so bent on believing that the only way for life to develop is as we know it. What bullshit lol. Why shouldn't carbon be replaced with silicon or something? Just depends wats available on other planets for life to develop and if the conditions are right it will develop. Maybe radically different conditions if it's to start using different elements altogether.


"I don't care about politics"
Then politics doesn't care about you either. Truth. You've got to make your voice heard, if you want to be listened to. But that's too logical for some people, so let me go a step further. Not making your voice heard, leaves other people free to hijack it by speaking on your behalf, even if they don't actually give a shit about you. That's politics. So, make your voice heard. That's not a quote from anywhere. That's just me.
