- sigafoo, on 07/14/2009, -0/+18There was a very interesting TED video explaining this in detail a while back on here
EDIT: Found!

- radicaldementia, on 07/14/2009, -0/+6Interesting article. A similar form of communication is used in the cells of multicellular organisms, particularly during embryogenesis. A form of quorum-sensing decision making is used by stem and progenitor cells when an embryo is developing to help different cells specialize at the right place and in the right ratios. Actually, virtually all cell-cell communication in the body relies on secreting and detecting signal molecules at specific concentrations, one well-known group are proteins called hormones, another group would be antibodies secreted by B-cells in the immune system. I don't know if these methods of decision making evolved directly from the QS in bacteria, but it's interesting to see how at the cellular level, our bodies still behave a lot like groups of bacteria.
Here's the full research paper. http://www.nature.com/msb/journal/v5/n1/full/msb20 ... - Xaevier, on 07/14/2009, -1/+4That's like getting sued for using the world Excalibur...

Data: I can not report any significant access

- elarson, on 07/14/2009, -0/+2The key to killing all bacteria is the key to destroying all life on earth. Careful!

- ironlung, on 07/14/2009, -0/+1The article isn't going into much detail. Quorum sensing 'happens' when a molecule is present in a large enough concentration (in layman's terms). The idea that it depends on the environment is not novel, and has been known for a long time. If these researchers had discovered it, this would be published in something like Nature and not Molecular Systems Biology. I think the author of the article probably misunderstood what these guys were saying. I'll dig up the original paper and post about it later.
Edit: I just skimmed through the original article. They are compiling data from the literature and coming up with a model that they support with their calculations. I never want to say anything in science is not novel, because you can always learn something new but the idea is not new at all. Perhaps their calculations provide a better way of estimating new quorum sensing systems. - magnumpela, on 07/15/2009, -0/+1Are you a nerd for posting this, or am I a nerd for knowing what you mean?
- scotchw, on 07/14/2009, -1/+2I knew the Descolada were Varelse
- RC212V, on 07/14/2009, -0/+1+++Excellent Link
If researchers can understand the signaling used in cell differentiation that should be a huge step towards regenerating organs, limbs, and tissues.
For bacteria this means we'll have another really powerful tool to fight decease but it should also be a huge benefit for maximizing the potential of beneficial bacteria. I could see this being used to improve the usefulness of bacteria being engineered to produce hydrogen for fuel cells or the bacteria that can help clean up chemical spills. - PhilMoskowitz, on 07/14/2009, -0/+1Are they going to be able to "turn off" bacterial growth?
- inactive, on 07/14/2009, -0/+1maybe this is why garbage stinks so bad
- lostngone, on 07/14/2009, -1/+2Great! However I can't seem to find it, Bacteria doesn't seem to be listed as a language on Rosetta Stones page. I hope they update it soon!
- theamazingkort, on 07/15/2009, -0/+1I hope uncle martin here doesn't realize that I pissed my ***** pants.
- liquisoft, on 07/14/2009, -0/+1***** amazing, dude. Seriously. :-)
- ophello, on 07/14/2009, -0/+1They dont turn off growth, they turn off communication, which prevents growth.
- grubeater, on 07/14/2009, -0/+1Yep, she did a damn good job explaining it all too! That wasn't too long ago either....
- volume909, on 07/14/2009, -0/+1Okay where do i download it illegally?
- ironlung, on 07/14/2009, -0/+1I meant the gist of the idea is not new at all. I didn't have enough time to edit properly.
- Moralogic, on 07/14/2009, -0/+1Well, since Rosetta Stone is an actually stone, and not just the company that has annoying commercials I see too much. I have to say Google should win that case. Of course they could also shoot their search engine rank down to ***** them out of the same amount of money.
- XTomTomX, on 07/14/2009, -0/+1Only in your pants.
- MrSparkle666, on 07/19/2009, -0/+1It's funny how this article talks about "quorum sensing" in bacteria offhandedly, like it's something that we've know for ages, when in fact the discovery that bacteria communicate in this way only happened a few years ago. I remember reading an article about it in Scientific American not long ago ago when it was the current "big discovery." Science these days moves so quickly sometimes it's hard to pay attention.
- digitalArtform, on 07/14/2009, -1/+1You guys are so jealous.
- brettmjohnson, on 07/14/2009, -0/+0In other news, bacteria have learned to speak Italian, in hope that they might date that model.
- Mican, on 07/14/2009, -3/+1Rosetta Stone sucks.
- gvlax50, on 07/14/2009, -5/+1These comments suck, as does the explanation of the process in this article.
- digitalArtform, on 07/14/2009, -7/+1Turns out they are talking about me, right?
:D - Astark, on 07/14/2009, -6/+0I hope they talk like the black dolphins from Family Guy. I see you breathing out your hole! You know I got jokes!
- tEhKewleSt, on 07/14/2009, -9/+2Michael Phelps is somewhere celebrating this news with a nice fat bong toke...
