Encoding Messages In Bacteria
sciencehabit writes "Researchers have invented a new form of secret messaging using bacteria that make glowing proteins only under certain conditions. In addition to being useful to spies, the new technique could also allow companies to encode secret identifiers into crops, seeds, or other living commodities."
Maybe someone already left a message for us.
Fuck, base, the enemy intercepted our communication. I SNEEZED, I REPEAT, I SNEEZED.
This is base, IDIOT, this is why your parents teach you to always hold your hand in front of your mouth.
Next they can get to work teaching them to predict the future by zapping them with laser beams.

Haha, what the hell is a "sork", stupid bacteria
Yeah baby, watermarking seeds. Mmmm ...
And what's the insight offered by a random scientist on this?
"It's a really cool idea," says Kenneth Suslick, a chemist at the University of Illinois, Urbana-Champaign.

Encoding language into DNA has been used in several art projects, for instance this one by mad professor of literature Christian Bök (work still in progress, I believe). DARPA imitates art?
Something about these two words being used together sends shivers down my spine.
It looks like Gravious gave his knife missile the slip.
That is not a complement. I'm surprised this made it into PNAS.
It just shows what some marketing & spin can do to ho-hum scientific research. Jacks to Jazz!
WE began the Descolada!
Cough ... Cough ... what's that you say? No my seeds aren't patented I just took a huge toke.

This is a bad idea, because in genetics, you only have the 4 letter A, C, G, and T. What kind of message could you make with those? There aren't even any vowels!
but they have the cure for NAS
"Chalmers, a man with a keen sense of humor, had used the example of a man looking down on a microscope slide and seeing the bacteria formed into the words 'Take us to your leader.' Everyone thought Chalmers's idea highly amusing."
"No headache, I just feel terrible. I think I got the flu."
"No my dear; that is just the latest way to say I love you, yuk, yuk, yuk..."
Somehow I wonder how great of an idea this is ;)
I don't really see the current research as being applicable to the lucrative crop seed production market very soon. But I'm sure Monsanto and others are watching this research with interest.
One huge problem I see with this gene matermarking idea in commercial crop production is that genes are moving across nature anyways. This fall after spraying some of my Liberty-Link canola with round-up so I could combine it straight (kind of like running just "make install" instead of "make; make install" ;). After 10 days there were still a few very green spots in the field. I have a strong hunch that those spots had round-up resistant genes then them, probably growing up from volunteer seeds in the soil. Now I've never ever grown round-up ready canola there before. Some was grown a half mile away or so. People have been discovering round-up tolerant canola growing in all kinds of weird places. Due to whatever cause we know for sure that roundup-ready genes are moving without human intervention. Also more and more weeds are round-up tolerant but that might just be because of over-use of round-up.
In any case, watermarking seed isn't viable in the long term. What Monsanto is probably more interested in, is making single-generation crops. If the farmer can't hold back seed, then they've got a guaranteed market. In north america, single-generation wheat has been pretty much shot down by the farming community. But abroad, it's a lot harder to say no to that kind of thing.
... that did it. Encoding messages into DNA it then deposited in faeces left on the clothing of guests of Sleeper Service, if I recall correctly? And didn't the Good Times Gang know all along?
Descolada anyone?
Didn't I see this in a Star Trek TNG episode...?
Now Geico will have one more place to stick their ads.

These techniques are old hat. We've been modifying bacteria to serve as biomarkers for a long time now. They're used in quick and easy assays for chemical contaminants, for instance. Basic idea is just that you have your "certain condition" from the article be one with, say, arsenic. The bacteria create a fluorescent or coloured compound as a result and you have a positive hit for contamination.
So before we get too deep in to evil corporations tracking their products, keep in mind that the tech has been around for a long time and if it was a valuable thing to do, they probably already would. But it seems like there's relatively little point in, say, Monsanto tracking crops by inserting a gene when we have much simpler options like PCR available.
Them brainy gitz just need ta get workin' on puttin' thinky bits inter fungus, not germs!
Iain M Banks had a spy character in his book "Excession" encode messages on bacteria as a secret communication channel. However, the messages were successfully intercepted.
Good book. I enjoy his Culture novels.
No sig. Move along - nothing to see here.
Bob sends Alice a cryptographic message encoded in DNA. Alice is unable to decrypt the message using standard techniques.
However certain techniques of combining the message with a similarly formatted DNA compliment of her own can often enable Alice to successfully identify Bob.
So, you put your message into the DNA. Hope you retrieve it within a few generations. Plants and animals change. DNA gets exchanged and mutated.
These changes could be considered bit errors, making "DNA encryption" and "DNA encoding' kinda futile. And good on ya if your message and someone else's get mixed up in the field.
Oh, and here's another thought... What if those "dead DNA areas" where you stored your message are simply DNA that required some exotic condition to express? You message might be lost if the plants all die off. Or worse, your message might be "RUN IN TERROR, Citizens of Earth! Our flesh-eating KUDZU will kill you all!"
Coin a phrase like that and then the genetic engineers are going to wonder why every thinks they are evil. Why even throw that neologism in there? The article was cool up to that point. Stupid. Show some respect for life. No, I do not accept your jaded world view. Ask yourselves why you speak like that. Go stand in the corner and think about what you just did.
Do they think they are being cute and conditioning the world to a deeper underlying agenda? There is no destiny. You have free will. Every day you make choices. Your choice was to use the phrase 'Living Commodity'.
Monsanto, why do you choose to be evil?
Yeah, but you just have to watch one episode of CSI to realize how tough key management is when you leave a copy of your private key on everything you touch...
The first thing humans will learn to program in genetic code will be comments. :P
