And man said let there be cyborg: Rat Brain Robot - YouTubeSomehow I doubt this is anything dramatically different from the already reasonably well-established field of FPGA computing.
FPGA = field programmable gate array. FPGA's can be dynamically reconfigured on the fly.
Electric shock therapy? Well, yes, there is some benefit to this. But there is a big difference between using electromagnetic fields on the body and inducing a current through it.
There are only two possible effects of electromagnetic fields on biology:
1. Deposition of heat. Electromagnetic fields do carry energy, and can warm of cells. You have to use a huge amount of radiation to have any biological effect in a warm-blooded animal like ourselves, though, so that this is almost never a danger.
2. Chemical reactions. Chemical reactions can be caused when the energy per photon in the electromagnetic radiation is large enough to start kicking electrons out of their orbitals. This starts to happen in the ultraviolet range, which is why UV radiation from the Sun causes sunburns and can cause skin cancer. No radiation lower in frequency can do this, which means that any radiation in the visible, infrared, microwave, or radio range is perfectly safe, provided the total energy deposited isn't too high.
Magnets themselves fall under electromagnetic fields in terms of how they can impact biology. And in realistic situations, it is just not possible to use a magnet to produce anywhere near as strong of electromagnetic fields as we experience on a daily basis. So the use of magnets in therapy is pure woo.
When I had an MRI My belt buckle was being pulled so hard by the magnetic field that it was like someone had grabbed it and was trying to drag me. MRI induce very powerful magnetic fields and these fields have no effect on the body. I can accept at the most that magnetic fields can cause disorientation in birds and the such but in all earnest using magnets to cure ailments is tantamount to this:There is still research into the use of electromagnetics for therapeutic uses for neurological disorders. I mention deep brain stimulation, no likes doing that because it is really invasive. I think it is just a technological hurdle we have to over come and not a scientific impossibility. Using permanent magnetics wouldn't do anything such as on your fridge because they are too weak and not really directed at doing anything specific.
Something fun I read to day that relates to this topic.

I did wonder why that was.Many countries have a national flag, and separate flags for their constituent sub-groups. The Union Jack is made up of the flags of England, Scotland, and Northern Ireland (though Wales is conspicuously missing).
I think the calming effect comes from drinking something nice and warm. Hot tea has the same effect on me. Caffeine is a stimulant, but if you get a lot of it, you can develop tolerance so it'll no longer affect you.Perhaps sedative is a better word... I feel calm when drinking tea! I have african rooibos, ceylon gardens, orange jaipur and indian spice and all of them have a calming effect! (it is black tea)
Watch for the massive explosions triggered by annihilating Englishmen in New YorkThe USA is the "alternate universe" of the UK akin to "matter versus antimatter".
Isn't the nucleus the densest part of the electron cloud for s orbitals?Nothing. The innermost electrons of an atom are routinely within the nucleus. Not that often, because the nucleus is very, very small. But it happens.
No, no no, please don't confuse dinosaurs with every other extinct reptile!So what do we know about the evolution of dinosaurs? Quite a lot! We have, for instance, just discovered evidence that Plesiosaurs, a type of aquatic reptile, gave birth to live young.
Yes, it is! Well, for the s1 orbital, anyway. If I remember correctly, it remains the highest-density location for all odd orbitals.Isn't the nucleus the densest part of the electron cloud for s orbitals?

That would be a classical black hole, and yes, it would be invisible, except for the fact that it blocks out the light behind it and that we can see stuff falling into it.If an object were able to absorb all light and not produce any heat, would it be completely invisible?
Nothing short of a black hole.Are there any elemental compounds that come close to achieving such an effect?
So all objects, outside of black holes of course, must reflect light to some degree?
Yes, basically. Just bear in mind that there's a lot more than reflection going on. You also get scattering of light in essentially random directions, you get absorption of light at certain wavelengths and emission at other wavelengths, and objects are transparent to certain wavelengths.So all objects, outside of black holes of course, must reflect light to some degree?

Scientists hiding events by creating a hole in time , Top Story - ecPulse.comYou could make a new type of clothing fit for an emperor!
Haha, well, you can't make fabric out of dark matter (dark matter doesn't stick together, so it can't be used to make anything), but it'd just be invisible itself if you could. Wearing invisible clothing would just make you look nakedSo if I designed a clothing line that used dark matter as a fabric, we all could be invisible?
Let's see.Here's one for ya mate: TOP TEN UNSOLVED PROBLEMS IN PHYSICS
1) Obviously not all the dimensionless parameters are calculable. Some may be, we don't know how many. But certainly not all of them. The idea that this is possible was basically only ever a pipe dream, and the discovery of spontaneous symmetry breaking has basically put the nail in that coffin.
