Linked are a couple things I found that have been previously
posted and are at least vaguely related to this Idea.
We know that at least some birds can directly sense the Earth's
magnetic field and use it to fly long distances to reach
particular
destinations. And we know that sharks can
directly sense
electric
fields. Both of these things (and perhaps others in Nature
waiting
to be discovered) are natural biological characteristics that are
consequences of certain genes, or sets of genes, getting
expressed.
Some day humans might like to enhance themselves with new
senses, beyond the usual six or so (it happens that some blind
humans can do limited echo-location, like bats and dolphins;
perhaps a general enhancement of that is worthwhile?).
Other extensions to existing senses are reasonably obvious;
many insects can see ultraviolet, for example. And some
animals (like snakes) can see infrared. Not to mention, recent
research
shows some of humanity's color-vision genes are on the X
chromosome, giving women an advantage over men, in color-
perception. And we all know that dogs and other animals can
hear higher-pitched sounds than us (and some, like elephants,
can hear lower-pitched sounds).
Logically, the way to go about doing such enhancing will involve
genetic engineering --transferring existing genes from one
organism's chromosomes to another organism's chromosomes is
practically routine these days. We simply need to identify all
the relevant genes, first.

// Female color vision // |

Could there be an enhancement to Female Monochrome Vision that allows them to notice that it says "OVERDRAWN" on the bottom of their bank statements ? |

If ever something was GM magic, this is it. We
know enough to swap colour receptors in the eye,
but that's about it. If you want ultrasonic hearing,
you can't just plug in a bat gene and away you go.
You'd have to modify the entire developmental
pathway of the ear, involving somewhere between
tens and hundreds of genes and, more particularly,
regulatory elements, very few of which we
understand at all. Then you'd need to allocate
parts of the brain to make sense of the
information. |
|
|
Almost infinitely simpler to do it prosthetically.
You want ultrasonic hearing? You can have it
tomorrow in the form of a heterodyning hearing
aid. Want it by GM Magic? Give us a few decades;
and then a few more if you also want it to be turn-
on-and-offable. |
|
|
See ? We've been telling you, again and again, cybernetics and prosthetics are the way to go, not muddling round with DNA molecules ... |
|
|
Besides, that sort of thing can only be compiled in at build time. What happens when your kid gets to be a teenager and suddenly decides they don't want ultrasonic hearing any more ? Try to imagine the sulks ... and it's ALL YOUR FAULT .... |
|
|
[MaxwellBuchanan], some of what you are talking
about refers to the "homeobox" or "hox" genes, which
are responsible for the overall form of an organism
*and* its parts, like organs. Thus relatively minor mods
to the genes responsible for the formation of the
cochlea should allow both higher-frequency and lower-
frequency hearing. |
|
|
I'm sure that some of what you are talking about is
quite real, like copying the electric-field sense of
sharks. I see the copying of that as a more longer-term
thing, than a short-term thing. Dare you say we will
*never* be able to learn enough about genetics to do it? |
|
|
/Then you'd need to allocate parts of the brain to make sense of the information/ |
|
|
I was thinking about this in the context of the Isis and Augi stories. A lot of the apparatus in the brain that makes sense of sensory inputs is probably sitting there idle. It is difficult to grow bat ears and hook them up appropriately. But could one sidestep that with a prosthesis which then delivered the input to that region of brain, perhaps magnetically? |
|
|
I have some worries about unused brain regions and their competence to do real work. Can someone blind from birth see if his eyes are repaired? A good side project would be to exercise the nondominant parts of the brain which could do work but don't, instead coasting along with the strong side doing everything. |
|
|
//[MaxwellBuchanan], some of what you are

the "homeobox" or "hox" genes, which are

|
|
Actually no, because I was assuming that people
would still want
the usual numbers of limbs and vertebrae in pretty
much the
conventional arrangements. Hox genes are highly
pleiotropic, but
their main effect (and the only one we really
mostly understand) is
on body segmentation, and the assigning of
segments to functions
(in humans as well as in more obviously
"segmented" animals). You
really, really don't want to go pissing around with
hox genes unless
you really know what you're doing and/or would
like major
alterations to your personal geometry. |
|
|
The things I am talking about are more subtle, and
almost
completely not understood. Ask a developmental
biologist why the
cochlea grows in a spiral, and he'll be stumped.
Ask him why the
human cochlea has a different shape from that of
a fruitbat and he
won't have a clue. What you need to understand,
[Vernon], is that
we really have almost no idea whatsoever how
_any_ genes
influence things like shape and proportion, except
in cases of
extreme abnormality. |
|
|
For example, we know which mutations produce
short legs
(achondroplasia) in bassett hounds. But we
haven't even the
faintest inkling of an idea of which genes make
their
heads domed, or
why their dewlaps are longer than in other breeds.
We don't know
why your pinkie is shorter than the other fingers;
we don't know
why your cousin's ears stick out; we don't know
what genes gave
Marilyn Monroe that particular smile. |
|
|
What you propose will, of course, eventually be
possible. But in
the blinding light of modern molecular genetics,
few people realize
how little we understand about some very, very
basic things. At
the moment, trying to do what you propose would
be roughly
equivalent to asking Leonardo da Vinci to change
the architecture
of a microprocessor. |
|
|
So, I contend, this idea is a prime example of GM
Magic - see help file for details. |
|
|
8th is married? Is she having counselling? |
|
|
So far we've concluded only that [8th] has regular
contact with a female stereotype. |
|
|
[MaxwellBuchanan], if it can be done at all, then it is not
magic. "When" doesn't matter here at the HalfBakery. |
|
|
Again, I respectfully refer you to the help file. |
|
|
" Dare you say we will *never* be able to learn enough about genetics to do it? " |
|
|
No, but I do dare say - well, never mind, [Max] just said it. |
|
|
//This implies quite poorly that we all have latent
electro-sensory capabilities.// |
|
|
A more direct proof can be had with the aid of a
paperclip and a conventional 13A socket. |
|
|
As to the idea, well, whatever. As an alternative,
wouldn't it be cool if we all had superpowers? Just
add nanotech. |
|
|
Whatever that female color vision gene, is I seem to have picked it up. |
|
|
What does this mean? Did I absorbed my twin sister in the womb or something? |
|
|
The only explanation is that you are one of those XX testosterone -insensitive folks, 2 fries. |
|
|
Well, it's not Klinefelter syndrome where guys have an xxy chromosome... or at least I don't match the profile. I'd pit my color vision skills against anyone on the planet though. Every subtle hue change on the hue tests stand out like sore thumbs to me. |
|
|
Must be my kaleidoscope eyes... |
|
|
If you could ever modify your genetics for hearing ultrasonic audio, perceive electric fields, and see a wider light spectrum, your appearance will be an obstacle to mate, having descendance, and pass on those great genes. |
|
|
Are you saying that I personally would be rendered unattractive by these improvements? Because from where I am starting it is going to take much, much more than that. |
|
|
Or maybe you imply that my new abilities will make my own potential mates seem unappealing because I will be able to see their auras and hear their bowels gurgling from a distance. Fortunately for them, my standards are already set very low. |
|
|
// Must be my kaleidoscope eyes... // |
|
|
Your eyes are triangular, and rattle when they're shaken ? Wow ... cool ! |
|
|
More prismatic really, being three dimensional and all, and they shake themselves, but yeah other than that... it's pretty cool. |
|
|
This is how I see bright light sources, [link], but they are overlaid by a torus of magnetic-field looking lines, caused by the interference pattern of aligning colors of the spectrum which rotate as the point source or I move in relation to one another, which is not shown in the image. |
|
|
It's quite pretty, but can make especially sunny days after it rains a bit bothersome with all of the reflected glints casting their own auras. |
|
|
Looks to me like corneal ulceration or, possibly,
something cataracty (or pre-cataracty) in the lenses.
You should definitely see an opthalmologist. |
|
|
A kaleidescope, and now a waterfall as well ? That's not a problem for an optometrist, it's an opportunity for a travel agent... |
|
|
// Looks to me like corneal ulceration or, possibly, something cataracty (or pre-cataracty) in the lenses.// |
|
|
It's caused by something called Higher Order Abberations of the eye. Just a funky shaped cornea that wasn't detectable before the advent of lasic surgery screening. Like so many other perceptual things in life, I thought that everyone saw light the same way I do. |
|
|
I think that might be part of human nature, to believe yourself to be normal until finding out otherwise one quirk at a time. |
|
|
"Bomb, return to the bomb bay ..." |
|
|
// my skin is sensing it and acting upon it // |
|
|
Not exactly - your skin, or rather molecules within your skin, are reacting to incoming UV photons. "Sensing" and "acting" imply the existance of a feedback loop, albeit a reflex. Many very simple organisms which lack a nervous system or brain - plants, jellyfish, geography teachers - demonstrate phototropism, or will seek nutrients or avoid damaging stimuli, but they don't "sense" the stimulus - they react locally. Light falling on a plant stem inhibits the local production of auxins, which reduces the growth rate on that side, causing the growing stem to bend toward the light source - a negative feedback system. |
|
|
There is no remote processing in such a case, unlike a cat being hit by a paintball - in that case, the pain signal from the point of impact is transmitted to the brain, which reacts by causing the cat to run away, HAHAHAHAHA !! |
|
|
There's a YouTube channel called Cody's Lab where a guy does science up in his ranch. One such science that he did was to surgically implant a rare-earth magnet into his fingertip under the skin. He was then able to sense magnetism and electricity through his fingers - being able to tell, for example whether a particular wire was plugged into the mains and feeding current or not. I'd find a link, but corporate web-browsing. |
|
|
/However, if were all walking around today with latent electro-sensory capability, we certainly have no way of bringing this to the conscious fore, and have no interpretive means to take that information and turn it into signals that mean something for us./ |
|
|
My latest endeavor with the Isis and Augi characters deals with this exactly notion, if anyone feels like visiting the Spinal Cord Intercept page. |
|
|
[Ian] are you implying that bifocals, although
commonly touted as "lenses", are actually some sort
of psychoactive thing? |
|
|
That doesn't at all jibe with political leanings, though. |
