Cyborg Revisited
Last year Phil and I had one of our unplanned blog waves. That wave was about everything cyborg:
It might be a stretch to say that "Newsflash" is about cyborgs, but it made the point that future nanomachines might bear a striking resemblance to yeasts or other life. That fact might prove particularly helpful within living systems. If, for example, a medical device could be powered by ATP like the rest of your body, you wouldn't have to worry about batteries running out, or needing to be surgically replaced, or leaking.
The work on living machines continues in Israel:
Itamar Willner, who constructed the molecular calculator with colleagues at the Hebrew University of Jerusalem in Israel, believes enzyme-powered computers could eventually be implanted into the human body and used to, for example, tailor the release of drugs to a specific person's metabolism.
Such a device could become an onboard doctor, pharmacy, and drug manufacturer. It could diagnose a problem, prescribe a solution, manufacture, and release. Perhaps it could also insure that you get perfect nutrition from a less-than-perfect diet.
This type of technology may be required to fully realize life extension.
Last year's cyborg wave was followed by posts on Organic Electronics and Organic Molecular Transistors.

A good example of true cyborg technology is the cochlear implant, or artificial ear. It operates by direct stimulation of the auditory nerve, bypassing the cochlea. First it receives analog sound input through a microphone, the converts the pressure waves into digital information. Then it processes the data according to selectable reprogrammable "mappings". Lastly, it converts the processed data into analog electrical signals sent to the nerve. Interestingly, those without an implant can listen to the results. It has an audio output channel so that technicians may listen to the various programmed mappings.

Binkley:
Those who choose to get a cochlear implant are told it's a "no going back" proposition. The process of bypassing the cochlea is, apparently, permanent. No hope of ever getting natural hearing back.
Of course those who are totally deaf have probably accepted that. I'm sure some patients are on the fence with this decision.
