DNA circuits used to make neural network, store memories

Even as some scientists and engineers develop improved versions of current computing technology, others are looking into drastically different approaches. DNA computing offers the potential of massively parallel calculations with low power consumption and at small sizes. Research in this area has been limited to relatively small systems, but a group from Caltech recently constructed DNA logic gates using over 130 different molecules and used the system to calculate the square roots of numbers. Now, the same group published a paper in Nature that shows an artificial neural network, consisting of four neurons, created using the same DNA circuits.
