Harvard Creates Cyborg Flesh That's Half Man, Half Machine

From ExtremeTech:

Bioengineers at Harvard University have created the first examples of cyborg tissue: Neurons, heart cells, muscle, and blood vessels that are interwoven by nanowires and transistors.These cyborg tissues are half living cells, half electronics. As far as the cells are concerned, they're just normal cells that behave normally - but the electronic side actually acts as a sensor network, allowing a computer to interface directly with the cells. In the case of cyborg heart tissue, the researchers have already used the embedded nanowires to measure the contractions (heart rate) of the cells.
