>Genetic Similarities Within and Between Human Populations
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1893020/
>The proportion of human genetic variation due to differences between populations is modest, and individuals from different populations can be genetically more similar than individuals from the same population. Yet sufficient genetic data can permit accurate classification of individuals into populations. Both findings can be obtained from the same data set, using the same number of polymorphic loci. This article explains why. Our analysis focuses on the frequency, ω, with which a pair of random individuals from two different populations is genetically more similar than a pair of individuals randomly selected from any single population. We compare ω to the error rates of several classification methods, using data sets that vary in number of loci, average allele frequency, populations sampled, and polymorphism ascertainment strategy. We demonstrate that classification methods achieve higher discriminatory power than ω because of their use of aggregate properties of populations. The number of loci analyzed is the most critical variable: with 100 polymorphisms, accurate classification is possible, but ω remains sizable, even when using populations as distinct as sub-Saharan Africans and Europeans. Phenotypes controlled by a dozen or fewer loci can therefore be expected to show substantial overlap between human populations. This provides empirical justification for caution when using population labels in biomedical settings, with broad implications for personalized medicine, pharmacogenetics, and the meaning of race.

>muh 97% of scientists believe in global warming
>if you don't believe in global warming you are a racist conspiracy theorist
I believe global warming is happening naturally but its unstoppable and we can't do anything about it but adapt.
So I'm so glad you smug global warming fags and treehuggers got eternally BTFO.
>>8469629
Good for you. But the scientific consensus does support the idea of man-made climate change. Sure it does happen naturally, but we've drastically accelerated the process.
>>8469640
>(((scientific consensus)))
You mean a group of people refusing to consider any alternative research to the mainstream climate change narrative because they're too scared to lose grants and tenure.
Give it a generation or two and climate change will be replaced by another theory.
it's not okay to make fun of some people with disabilities that are the manifestation of their genes, but once we get to things like height, intelligence, and attractiveness, genes don't matter.
You wouldn't tell someone that has genes that results in them having a weak immune system which results in them having a disadvantage at life to stop complaining or work harder if they claim people with healthy immune systems are lucky, but it's okay to shit on semi normal people for having disadvantages phenotypical properties that are a manifestation of their genes.
Why is this?
it's actually all not okay
is there a gene that leads to a higher tendency for one to shit post on 4chan? If so, murder yourself.
>Why isn't the world a perfect safe space?
The world isn't going to pander to that kind of thinking. And a lot of people ABSOLUTELY do mock people for disabilities that are the manifestation of their genes.
t. someone with shitty genes.
Any particular reason why we aren't colonizing the moon?
Why go through all the effort of trying to colonize Mars and sending people there? The moon is much closer so it wouldn't take as money and man power to get there and set up atleast a base or two.
>>8469247
The moon's gravity is even shittier than Mars
A lunar day is 29 days long whereas Mars is a near perfect 24 hours
The moon is covered in regolith dust that is like a cloud of tiny razor blades because the thing has no natural atmosphere or erosion to smooth them out, it's like the whole fucking place is made out of Captain Crunch
>>8469247
Actually most space agencies are looking into a moon habitat. Moon bases are possible, but Mars visitation is essentially theoretical at this point.
What's the point of colonising the moon? Let's just build a camp on a desert, lock there up couple of people and make them live on tinned food and limited water supply, buses are cheaper than aircrafts, they rarely blow up, it's easier to help the people should something go wrong and it will give us as much scientific knowledge and advancement as lunar base
How hard would it be for a lone wolf or a terrorist cell to develop an antibiotic-resistant bacteria and spread it to livestock shows or large gatherings of people?
I imagine it wouldn't be tough at all, especially with a basic setup and some skilled people. Like the poison gas attacks by that cult in Japan, it would take time but could be devastating if executed correctly.
Why isn't this done?
By the way, I tried posting this on /pol/ and gave up after all they posted were frogs and trump memes.

I have a stupid taxonomical question.
If dinosaurs are reptiles and birds are dinosaurs, why aren't birds reptiles?

I don't think dinosaurs are considered reptiles
Why can't we adapt to climate change 50 years from now rather than prevent it? Climate change prevention costs billions of dollars and puts millions out of work.

You mean evacuate all the millions of people from all the coastal cities? And completely move all crop farms as well?
>>8468949
>You mean evacuate all the millions of people from all the coastal cities?
Why not? There are huge swaths of land for them to migrate to.
>And completely move all crop farms as well?
We'll have fucking lab-grown food by the time it's necessary.
Why does stuff hurt more when it's real cold out?
>>8468930
Plz give us an example for a "stuff"
>>8468948
Like if I tripped and scraped my knee on the ground or like closed the door on my hands or something, it seems to hurt more on a frigid winter day than say during the summer
Why is this? Is it the temperature change from the body to the outside that causes this?
>>8468953
Cold stimuli can activate pain receptors, same as heat btw
Hey guys, thought you might enjoy some pictures of the new fuel cell for SpaceX.
A few years ago one of the large manufacturing buildings in our small town got bought by a bunch of strange suits, supposedly by Boeing for special projects. Extremely tight security.
Even the shipping containers outside had biometric locks on them.
But a few days ago they brought this big fucker out and loaded it onto a barge, supposedly for "destructive testing".
Less than 24 hours later, it has already returned seemingly intact.
They could not have gone very far at all, so everybody is pretty curious about what they actually did.
I saw a few man-sized silver tanks that were being moved off the barge as they were venting.
My best guess is they only filled it partially and will be cutting the tank open to examine how well it held up. Supposedly the last one exploded due to a reaction with the resin in the carbon fiber and the liquid oxygen.

We had our midterm yesterday and the numbers we had to add were unreasonable. Four digits each! Here's hoping for the curve.
Who else's Computer Science professor is belligerent and psychotic?
We had our midterm yesterday and it asked for a polynomial-time algorithm for the traveling salesman problem.
Who else's chemistry professor is belligerent and psychotic?
We had our midterm yesterday and it asked for a concise and enantioselective synthesis of taxol.
Hey guys. The recent election has got me wondering the correlation between human biochemistry and political views.
It's no secret that men lean primarily conservative and women lean more liberal, but I haven't found any credible sources. Link related makes sense, but doesn't link to any data.
http://www.psychologicalscience.org/news/releases/political-motivations-may-have-evolutionary-links-to-physical-strength.html#.WCYX8y0rLIV
Though I don't have any studies to back this up, I agree with that a general correlation is extremely likely. The reasoning being that the same hormones associated with cooperative rearing and caregiving cause sympathy and concern for others well being before ones own well being. This leads to support of social programs like funding for education and at the extreme, welfair programs.
Hormones that are higher in males are associated with aggression and selfishness, causing high testosterone people to lean toward capitalism, lower taxes (less for them, more for me), and exclusion of other groups from sharing the same rights (gay marriage).
The problem with identifying a correlation and proving this is that hormone levels fluctuate throughout our lifetime. It would be interesting to see if this leads to changing polititcal views. Some people are also smart enough to realize that the rationale behind some ideas (selfishness leads to trickle down economics, group cooperation leads to collective increase in wealth and quality of life) might actually be sound, and they sacrifice their instincts for the greater good.
Then you have to see the effect of nature vs nurture. It would be a cool study if done well.
>It's no secret that men lean primarily conservative and women lean more liberal
Actually from a biological basis it's the opposite, Men are more liberal and Women are more conservative. A good example of this is reproduction.
But of course when politics is in play it really depends on the economic models involved. Models involving capitalism go both ways since while methods in maintaining old wealth require a conservation of valuable resources. Methods in acquiring new wealth require far-reaching actions that tend to break norms.
>>8468631
i think any genetic correlation will be alot more than just hormones.
im sure youll find a study like that here.

Is somebody doing astrophotography or amateur astronomy?
Celestron astromaster 130 eq with my S7 active
>>8468451
I have a friend who does.
He even built a telescope with a 1m lens from scratch - including grinding down the lens.
I do.
Canon 6d, 190mm f/5 corrected Newtonian, ISO 3200, 31x60s exposures, + darks.
It was the first image I took with my new Canon, before that I had a cheap DLSR which was not sensitive.
It was a bugger to flatfield because I was using a guide probe which made a weird vignetting thing and I never really had to bother with flats with my previous camera which had a smaller sensor and was thus less affected by the flatfield. I had to make an artificial flat from my subs, that took hours but worked pretty well.
