Tomorrow, I’ll hold a presentation on bio.display at the Iwasaki Lab of the Center for Advanced Biomedical Sciences at Waseda University in Tokyo, at 2:30pm local time. See Iwasaki Sensei’s page on what he’s mostly up to.
Today the Hungarian newspaper HVG mentions bio.display in a feature about 3D printers in general, and its use in edible printing & medical applications.
Using the same method to create the flashing signs, the researchers engineered a simple bacterial sensor capable of detecting low levels of arsenic. In this biological sensor, decreases in the frequency of the oscillations of the cells’ blinking pattern indicate the presence and amount of the arsenic poison.

A similar approach to that used in bio.display has been utilized by David Walt, a chemist at Tufts University in Medford, Massachusetts, and George Whitesides, a chemist at Harvard University. They use fluorescent proteins of various colors to be able to encode 49 different characters, thus being able to encode the 26 letters of the English alphabet and 23 different kinds of signs.
They imprint the messages by placing e.coli into an agar gel, just like in bio.display. To read / decode the messages one has to activate the fluorescent protein genes in the e.coli – the same mechanism used in bio.display to make the images emerge.
the bio.display project is featured on the front page of the Hungarian online newspaper HVG, together with other bio art projects.

The Fab@Home 3D printer I used to create the bacteria prints is now being utilized by hackerspace budapest, a new formation created by IT enthusiasts in Budapest, Hungary. I really hope they will make good use of the hardware & contribute to the effort of developing a cross-platform control software for the Fab@Home printer.
