I think you got the headline backwards- engineered systems use system algorithms to biological networks. Since after all, those biological systems have been doing these sorts of things, without being engineered.

That we rediscover biological mechanisms present in our own designs, we should not be surprised.

I think that the phrase "utilize similar" does not imply an order.

Anyway, I'm curious what would be the engineering counterpart of caffeine :)

caffeine is the engineering counterpart of caffeine.
