    Pretty detailed tiny image of the Flying Spaghetti Monster. How many noodly appendage comments will we see?

    With the growing number of sequenced microbes, we can search through nature's large trove of tools to find ones that fit the job," Levskaya said. "In our case, searching for light-sensing domains led us to use a photosynthetic bacterium." The students produced ghostlike, living photos of many things, including themselves and their advisors

    I wonder how far they are from being able to take a huge image of a processor chip pathway and use these microbes to lay out an eating path for another microbe to create cheaper chips. I'm guessing it isn't realistic in the near future, but as the progression builds towards more "consistent" bacteria, maybe we'll see more aggressive use of these discoveries for profitable reasons.

    That's my biggest question -- is anyone seeing private R&D scientists investing time and money in engineered bacteria that will be protected by patents or other IP protections? It's pretty amazing that TFA's discovery was by students.

      These bacteria are way too big to be of any use in modern photolithography. Assuming each one's square, and there's 1 per pixel, each bacterium takes up an area of about 6.5 square microns (1 100-millionth of a square inch). For comparison, the smallest production SRAM cell I can find is .25 square microns, and contains 6 transistors. That makes these bacteria 150x as big as a transistor, and even larger when compared to the features that make up the transistors and connect them together.

    E. Coli genetic engineering has been around for many years. Creating light sensitive strains, strains that make pigments, etc. is roughly appropriate for college level biology. I suppose it's kind of neat that engineers have taken notice, but it really is textbook stuff.

    In fact, even more simply, since the pigment was present/absent based on whether the bacteria were growing in the light, you can repeat this experiment at home: use any organism using chlorophyll for photosynthesis and grow it in patterned light: you'll get a "photograph" in green/yellow. That's an experiment even elementary school students do.

    You've got to give it to these people, though: they are excellent salespeople. Getting away with such trivialities as "engineering" and endowing bacteria with "new skills" takes both guts and skills.
    • You would be surprised how many "really basic" stuff any college student could do become cutting edge stuff if you JUST make them a bit smaller/ better /ect.

They add photosensitivity to the bacterium membrane, add pigmentation change, and hook them up.

    Scientists have announced that they have managed to create a gigapixel per square inch "light sensor" using only silver halide molecules coated onto a transparent plastic substrate. On exposure to light, some molecules change state by dissociating into pure silver. Exposure times of just a few milliseconds were all that were needed. This image is not visible to the naked eye, but can be "developed" using chemical processing to amplify the image to make it visible. The final image can be then fixed and rendered no longer light sensitive by bleaching out the remaining halides. The image is then rendered permanent. With its vastly higher resolution than ordinary digital CCD sensors, scientists are hailing the discovery as a breakthrough for creating ultra-high resolution images. They have also speculated that by creating a sandwich of light sensitive layers and colour filters, colour images could be recorded by the same process. The only question is, is the usual digital imaging that we have all grown used to doomed by this new process?
    • This revolutionary new chemical process, in addition to providing much higher resolution, also allows for a much greater exposure latitude than current state-of-the-art digital sensors, allowing for much greater levels of both highlight ans shadow details in high-contrast images. And this color process of which you speak should record much more accurately and vividly. All in all, I agree this breakthrough technology looks to be far superior to the current pitiful CCDs we are all used to. Perhaps a bit more
