I like the idea, but it might have to wait till there are no longer things around that magnets can screw up, like credit cards and hard drives.

That's covered at the end of the article. They say the field isn't strong enough to harm those things, but you are f*cked if you ever need an MRI scan.

Would it be possible to just get a magnetic ring to achieve the same effect without the whole 'implanting objects into your body' part?

Why not just glue the thing on your finger? Then it wouldn't be invasive.
(of course these romantics think it is cool to have it a "part of you") but as far as I know that is just aesthetics, not function, prove me wrong.

This really isn't a new 'sense', it's just another tool. You can hold a magnet in your hand, too, and 'sense' magnetic fields.
Also, I call BS on being able to sense 60hz fields from microwave ovens and stuff. Those photons are in all sorts of orientations.

I'll admit I've loved this idea since I first heard about it a few years ago.

Having said that, this article was bad, and the author should feel bad.  The new technology they get excited about isn't new, and the ignorance regarding an MRI is painful.

seems like he did read it to the end.

It wasn't an informative article. More of a propaganda piece.

I have a total hip replacement. Maybe I should have asked for a magnetic one.

The point is, a doctor once told me that if I ever need an MRI, they can aim the scan to avoid my hip. I'm not sure how that works, and if they screw it up, I could die, but that's what I was told.

True; it seems they should have interviewed a doctor about it or something. Instead, it's like the author cobbled together some information from google searches and made an "article."

It's a Gawker site, what did you expect?

I refuse to go there, most articles are just a paragraph or two, with a link to the story they stole  plagiarized were inspired by.

I'm pretty sure the effect would be having the magnets ripped out of your fingers and shot across the room at incredible speeds.

"It's not entirely known what the effects of such a scanner may have on an implant, and would that damage the MRI machine."

The MRI will not be damaged.  Your finger might.  Heat could be generated by induction.  Some metal implants could migrate within the magnetic field - this could be problematic with clips used to ligate blood vessels, but probably wouldn't be dangerous with a finger implant unless the finger was somehow restrained.

The most likely adverse event is that if your hand is within the area of clinical interest while the MRI is obtained, the image may be degraded because of the presence of the implant.

"According to most experts, the best and safest way is to get it on the fourth finger (ring finger) of your non-dominant hand. The idea is that, if something should go wrong, it's your least useful finger."

I disagree with this reasoning.

If I were given the choice of which finger to be amputated, it would be the nondominant index finger.  It is the most expendable digit, in terms of ability to retain function after its loss. Most people will readily adapt to the amputation of part or all of the index finger by transferring side and tip pinch to the long finger.

I agree that the nondominant hand would be preferred.  I also agree that one would not want to insert the implant into the pad of the thumb or index finger, as many activities require pressure onto the palmar surface of the tips of these digits, and a foreign body in the pulp could cause pain.

While I probably would choose to have this kind of implant inserted into my nondominant ring finger, it would not be because the digit is the most expendable, but because most of the important functions of that digit do not require direct pressure on the pad of the fingertip.  Also, if the fingertip implant caused a local infection and it were possible to limit the amputation to the DIP joint level, the hand would still retain most of the power grip function of the ring finger.

You might be able to feel the magnetic field of the transformer at 60hz. The article kind of retardedly calls it an electric field. The microwaves are at 2.45 GHz and you can feel those without a magnet if the microwave isn't shielded.

I'm with other people tho, this seems like a bad idea. It seems like a form fitting latex glove could be used.

James Rollins used this as a character hook in his most recent book, The Eye of God. The character had it in all 10 fingers, though. It seemed like a cool concept, but since I'm trying to get into a Radiological Technologist training program (X-ray, MRI, CT, etc) it just seems like it wouldn't be a very wise move on my part.

I think the message being communicated is, if you're getting crap like this implanted in your hands, a wedding ring probably not in your immediate future.

/what would this do to my floppy disks and VTR tapes?

Um, just put a magnet under a rubber glove. But then you're not a biohacker. Jesus Christ how much lower can we go?

I believe these have a history of coming apart inside people's fingers and causing horrific infections and heavy metal sickness.

Still, once that works out, I might want one. Kinda concerned about use of that finger though since I do a lot of work with my hands and it could get in the way.

Also, couldn't you get similar, non permanent results by superglueing magnetite powder on your fingers?

We could always call antibiotics `life extension`. That would lower the bar...

Fine, see how long you make it without modern technology. Go on, show me. No more running water, no more indoor plumbing, no more fridges, no more industrial-scale farming, no more doctors, hospitals, germ theory...

Show me. Or read about history. Can you handle that?

Or we could call sub-orbital hops "spaaaaace" and act as if the Death Asteroid is coming, how about that?

Medically speaking, This is a terrible idea.

When you put powerful magnets near your blood vessels, it calls and pulls all the iron in your blood into that one spot causing magneto-induced-hemorrhaging of the blood vessels because those vessels will accumulate iron to the point of bursting. Possibly also upping the chance of strokes and blood clots if the flow of blood is having its iron molecules detoured into one spot.
