Using photonic chips to control single photons in waveguides is a promising route to technologies based on the photons'quantum properties. The ability to measure entanglement on such chips is a key step in that direction.
With age comes wisdom, or so they say. The reality is that, with age, the ability to store memories declines. One way of tackling this problem might be to raise neuronal levels of the signalling molecule EphB2. See Articlep.47
Computers use transistor-based logic gates as the basis of their functions, but molecular logic gates would make them much faster. A report of DNA-based logic gates could be a first step towards molecular computing.
