\"FSM<\/a>New Scientist<\/i> reports that a “living camera” has been developed from bacteria<\/a>:<\/p>\n

A dense bed of light-sensitive bacteria has been developed as a unique kind of photographic film. Although it takes 4 hours to take a picture and only works in red light, it also delivers extremely high resolution.<\/p>\n

The \u201cliving camera\u201d uses light to switch on genes in a genetically modified bacterium that then cause an image-recording chemical to darken. The bacteria are tiny, allowing the sensor to deliver a resolution of 100 megapixels per square inch.<\/p>\n

To make their novel biosensor, Chris Voigt\u2019s team at the University of California in San Francisco, US, chose E. Coli, the food-poisoning gut bacterium. One of the reasons for that choice is that E. Coli does not normally use light – photosynthesising bacteria could have used light to prompt other, unwanted, biological processes.<\/p>\n

The researchers used genetic engineering techniques to shuttle genes from photosynthesising blue-green algae into the cell membrane of the E. Coli. One gene codes for a protein that reacts to red light. Once activated, that protein acts to shut down the action of a second gene. This switch-off turns an added indicator solution black.<\/p>\n

As a result, a monochrome image could be permanently \u201cprinted\u201d on a dense bed of the modified E. Coli.<\/p><\/blockquote>\n

I think it’s quite fitting that the first image made was that of the Flying<\/a> Spaghetti Monster<\/a>… \ud83d\ude42<\/p>\n
