Nature In example of something which you would think be a larger news story than it apparently was, at the end of Novemeber scientists released a paper explaining how they managed create bacteria which could be used to carry a current within an electronic system:
"Previous studies performed by scientists and collaborators at Lawrence Berkeley National Laboratory’s (Berkeley Lab) Molecular Foundry have made enormous headway toward cellular-electrode communication by using E. coli as a testbed for expressing an electron transfer pathway naturally occurring in a bacterial species called Shewanella oneidensis MR-1. The engineered E. coli was able to use the protein complex to reduce nanocrystalline iron oxide (Jensen, et al. (2010) PNAS.). Building off of this research, a group led by Caroline Ajo-Franklin, a staff scientist in the Biological Nanostructures Facility at Berkeley Lab’s Molecular Foundry studying synthetic biology, has now demonstrated that these engineered E. coli strains can generate measurable current at an anode."
Or at least a much improved version.
