BBC just posted an article talking about a recent invention allowing one central unit to control multiple nanomachines simultaneously. While they currently need a scanning electron microscope to change the state of the tiny CPU, it's a hell of a start towards crazy things like autonomous nanorobots.
And on a similarly geeky note, here's a link about neurons and silicon living in joyful hippie-like harmony: link! Looks like progress is being made towards integrating silicon and brainstuff. Hopefully it won't be long until we start to see some real-world benefit from neurocomputing.
