A team of researchers led by Martin Fussenegger, Professor of Biotechnology and Bioengineering at the Department of Biosystems Science and Engineering at ETH Zurich in Basel, have now found a way to use biological components to construct a flexible core processor, or central processing unit CPU , that accepts different kinds of programming. A special variant of the Cas9 protein forms the core of the processor.

In response to input delivered by guide RNA sequences, the CPU regulates the expression of a particular gene, which in turn makes a particular protein. With this approach, researchers can program scalable circuits in human cells -- like digital half adders, these consist of two inputs and two outputs and can add two single-digit binary numbers. The researchers took it a step further: they created a biological dual-core processor, similar to those in the digital world, by integrating two cores into a cell. Fussenegger was delighted with the result, saying: "We have created the first cell computer with more than one core processor.
This biological computer is not only extremely small, but in theory can be scaled up to any conceivable size.
Such 'computational organs' could theoretically attain computing power that far outstrips that of a digital supercomputer -- and using just a fraction of the energy," Fussenegger says. A cell computer could be used to detect biological signals in the body, such as certain metabolic products or chemical messengers, process them and respond to them accordingly.
With a properly programmed CPU, the cells could interpret two different biomarkers as input signals. If only biomarker A is present, then the biocomputer responds by forming a diagnostic molecule or a pharmaceutical substance. If the biocomputer registers only biomarker B, then it triggers production of a different substance.leondumoulin.nl/language/historical/alpha-bear.php

If both biomarkers are present, that induces yet a third reaction. Such a system could find application in medicine, for example in cancer treatment. For example, if biomarker B remains in the body for a longer period of time at a certain concentration, this could indicate that the cancer is metastasising. The biocomputer would then produce a chemical substance that targets those growths for treatment. He continues: "The human body itself is a large computer.
Its metabolism has drawn on the computing power of trillions of cells since time immemorial. His next goal is to integrate a multicore computer structure into a cell. Materials provided by ETH Zurich.

Mobile phones and cameras don't have watt processors to manage this! They are certainly extremely quick in recognizing our smiles almost instant. Not sure about the differences between the above implementation and the camera ones though. Just saw this whilst browsing sourceforge, didn't think it deserved its own thread but if it does feel free to make one.
I presume it uses the PS3 over Ethernet as a coprocessor board? If so, that's just a short step from offering many acceleration functions on PS3, including my dream of using it as a software synth. Do we have any details on PS3's PC integration?
