HP has created what some believe to be the fourth fundamental electrical circuit element called a memristor. Whether you believe we're headed toward the Singularity or not, advancements such as these at the nano level continue to support Moore's Law and the idea of accelerating change. The memristor HP created is only fifteen nanometers wide and could get as small as four nanometers.

The memristor works like this: flow charge in one direction across the memristor and resistance increases and then flow charge in the other direction and it decreases. The amount of increase or decrease is proportional to how much charge flows across it. Why is that so amazing and what does it let us do? What's so cool is that after the charge is applied to the memristor the amount of resistance left tells us how much charge flowed across it: that's persistent memory in case you haven't figured it out yet. What that lets us do is create computers that have memory that persists like human memory persists. Again, one step closer to the Singularity?
