A new study has found that an Inuit population in Canada's Arctic are genetically distinct from any known group, and certain genetic variants are correlated with brain aneurysm.

Geographically isolated populations often develop unique genetic traits that result from their successful adaptation to specific environments. Unfortunately, these adaptations sometimes predispose them to certain health issues if the environment is changed. The genetic background of these populations are often poorly understood because they live far from scientific research centres.

Canada's Inuit have higher prevalence of cardiovascular disorders, as well as increased incidence of brain aneurysms, than the . To learn about the possible genetic origin of these disorders, researchers at The Neuro (Montreal Neurological Institute and Hospital) of McGill University analyzed the genetic characteristics of 170 Inuit volunteers from Nunavik, a region of northern Quebec. This was done with approval from Nunavik Nutrition and Health Committee in Kuujjuaq, Nunavik.

Using exome sequencing and genome-wide genotyping, the researchers found several interesting traits among the Nunavik Inuit. They are a distinct genetic population, whose closest relatives are the Paleo-Eskimos, a people that inhabited the Arctic before the Inuit.

The Nunavik Inuit have distinct genetic signatures in pathways involving lipid metabolism and cell adhesion. These may be adaptations to adjust to the and extreme cold of the Canadian north.

One of these unique genetic variants correlates with a higher risk of , also known as , a weakening in the wall of a cerebral artery that causes ballooning. In serious cases the arterial wall may rupture, a potentially fatal condition known as a brain hemorrhage.

This study, published in the journal Proceedings of the National Academy of Sciences, is the first genetic study to highlight the genome-wide architecture of Nunavik Inuit with emphasis on natural selection in gene coding regions, from which may arise the genetic risk responsible for their predisposition to diseases such as intracranial aneurysm.

Non-European populations, particularly those isolated populations in remote areas of the world, are underrepresented, or not present at all, in genetics studies. Understanding the of non-European peoples, especially those isolated populations with unique genetic background, such as Nunavik Inuit, will improve our ability to deliver medical therapies tailored for them.

"In the case of the Nunavik Inuit, our results emphasize the need to provide effective neurological services," says Dr. Guy Rouleau, the study's senior author. "Future research will build on the findings to determine if these unique genetic traits increase risk of , and if so, what interventions can be designed to reduce this risk. Thank you to the study participants and the Nunavik Nutrition and Health Committee for their collaboration and input."

Many old stories of far northern peoples having all their females mate with all male non native visitors in order to try to renew their blood lines. They did this with virtually all visitors except those known to have religious objections, like priests, etc.

They somehow knew they were verrrrry inbred and wanted to escape a cycle that would lead to their extinction as a people if they did not get some diversity in the bloodline.

These were traditional people that normally would not do these things, but who wanted to survive.

The prevalence of Uranium in the region means these people have likely been flogged by all the Plutonium manufacture and explosions over the years.
They probably copped the worst of the "Revnant" effects it causes.

Spiritual remnant from previous big bangs is what I mean by Revnants.

My heart isn't beating at the moment either, as the last Critical mass explosion was on the 8th of June, in Colorado. When I try to restart it, it hurts like hell, so probably a least a few months before our hearts will start beating again.

Revnants cause heart attacks and aneurysms, by flogging people with Laughter and Crying , left , right , left right until your heart explodes.

BAN PLUTONIUM!.

Interesting remnant av a population we later see in Greenland as the Dorset; it is not crystal clear but the data support earlier data on admixture. They split from the rest of the Inuit about 15 kyrs ago, and then had another influx of Paleo-Eskimo 8 kyrs ago.

The bottleneck that led to having genetic problem after bottleneck drift was a mere 3,000 effective breeders, akin to the pop numbers of Archaics at their bottlenecks.

Stephen Hawking and I had quite a different outlook on the formation of the Super-Verse, but I like to think we respected each others perspectives.

This is mine ....
1 . The Singularity is a dimensionless space if you disregard time, it contains nothing, and is only time.
2. The 2 spaces in the Reality paper I wrote in 81 (G space and the 3d space) we call space grew from that dimensionless space .
3. Photons started forming.
4. As the weight of light increased, heavier particles (protons) started forming.
5. At this early stage of the Super-Verse, there was not enough Gravity/Weight to stabalise the proton shell structures with Time Dilation (Which is simply caused by spacial compression), so it started "Banging", i.e. protons structures collapse/explode back into photon structures.
6. Our Big Bang is something that happened a very very very long time after that.

I was talking to the Inuit Torbjorn, some of them (50yrs and older probably) will hopefully understand what I'm saying.

But the science is the science, I'm not really commenting on the findings beyond "The proton structures are the evolutionary soul of life" perspective.

So ...
This is my theory of 38 years ago...

Draw a scale on paper going down (i.e. Y axis) and the scale is in nC^3

Then draw the Electron and the Proton on their appropriate weight scale.
Then draw a skin line from the zero weight down around each particle and back to the 0 weight line.

(The Q.G.R. Might have better numbers for these scales but it explains it well enough,
Photons/EM fill the 1C^3 ~ 4C^3 weights
Electrons 5C^3~6C^3
And Protons 7C^3 ~ 10C^3
Neutrons 11C^3 and higher

Anything below the Proton equatorial boundary has a Time dilation high enough to prevent energy transfer.
The Heavier a particle is the higher it's time dilation boundary condition, so energy transfer is slower.

** The Time Dilated Skin back to the Zero weight or "Gravity curve" is Magnetism theory. **

1. Magnetism is an exposed deeper weight particles Gravity curve.

2. Proton weights occlude these deeper curves in non-magnetic crystalline structures.
(I.E. Visible matter is proton weight or lighter and Dark matter is all the masses below proton weight)
3. Polarisation is caused by the total G-Zero skins weight differential.
(I.E. The G-Zero weight boundary is light and the bottom of the G-Curve is heavy and aligns to the prevailing Gravity field(s))
