Scientists Make Biochem 'Brain' from DNA Strands

thebchuckster (2344102) writes "The building block of the Caltech neural network is double-stranded DNA molecules with loose ends. These loose ends then receive the input of single-stranded DNA, which, through DNA strand replacement, releases an output DNA strand.

Using this input-output mechanism, the Caltech team assembled four neurons that give out specific DNA strand outputs that serve as both 'yes' or 'no' indicators in themselves and also inputs strands into other neurons."
