    disagreeing with depressed people

    Among five higher order personality traits (the Big Five) there is a trait called Neuroticism. It describes a generic tendency to experience negative emotions. Correlation between Neuroticism and depression is ca. 0.7 which is similar to the levels of correlation between various tests for depression/anxiety.

    CRISPR-Cas9 possilities

    I am a bit confused about what exactlty will be possible with this tech. Imagine the technology is perfected and we are indeed able to perfectly edit DNA of every cell in the body. IT surely opens posibility of genetically engineering embryos - but what about adult humans? Could we alter traits of adult organisms and if yes, to what degree?

    Is Psychology not a real science?

    Psychology is a science because scientific method is used in it as in any other science. Psychology uses scheintific methods of collecting data, analyzing them, conducting experiments etc. And psychology of today is vastly different from the one 50 years ago. It is turning more and more into direction of applied neuroscience - more and more use of brain imaging and hard data rather than hypotheses about phalluses.
  5. What are possible applications of magnetic brain stimulation besides treating depression/anxiety? Can it be used to change certain abilities of the brain or change personality traits? I think it's a fascinating technology that warrants more discussion here.
  6. What's the difference in function between left amygdala and right amygdala/ What function do various sub-parts of the amygdala have?

    Earth spinning at lightspeed

    What would happen if the Earth suddenly started spinning at the speed of light? Since its mass would go to infinity in infinitely small period of time, would it immediately turn into a black hole with infinite mass exerting such a gravitational force to start pulling the entire universe towards itself at lightspeed?

    Why can't natural killer cells target cancer cells?

    We will be able to do that soon with most cancers. We already have CAR T in use https://www.cancer.gov/about-cancer/treatment/research/car-t-cells We also have drugs like Ipilimumab and Pembrolizumab that "force" the immune system to attack cancer cells. A combination of Ipilimumab and Nivolumab wuadrupled 5 year survival for metadtatic melanoma

    Ukraine and Russia

    Petro Poroshenko with Ukrainian army soldiers. One of them carries the logo of Waffen SS Totenkopf Viking division: Its not an isolated case - there is at least one official Interior Ministry formation that uses insignia of Waffen SS (yes, two of them at the same time) as official emblem.

    Ukraine and Russia

    This has been more or less the case since 1991. Even though majority of Ukrainians use Russian, the sole official language since 1991 has been Ukrainian. Yanukovych finally changed that iin 2012, by granting Russian the status of a regional language - and there was a massive fistfight in the parliament over that. After Euromaidan the law was abolished and further restrictions on the use of Russian have been made - ban on import of Russian language books, quotas in media etc. among other things. Mind you, the whole conflict isn't solely about language, far from that. Linguistic policy is just the tip of the iceberg.

    Ukraine and Russia

    I think that's it Having a nationalist French government in Canada trying to violently impose (with help of far right/neo Nazi "activists") French language and anti-English/anti-American political narrative... It is so unlikely that it sounds almost comical. but that's what's happening in the Ukraine - the current government is systematically trying to eradicate Russian cultural/lingustic heritage in Ukraine even though 50-60% of Ukrainians use Russian as their main language and the two countries are as linked to each other as England and Scotland.

    Ukraine and Russia

    Like seriously? If the aforementioned far-right Quebecois violently took power in Canada, declared French to be sole official language, banned all English langage media and declared Anglo-Canadians to be invaders who oppressed the true (French) Canadians for centuries - then an armed revolt in multiple regions of Canada would be certain. And in that case, US will have full right to intervene in Canada in order to protect its brethren people.

    Ukraine and Russia

    I may say, yes and no. The southeastern part of Ukraine was deprived of any sort of political representation after a violent coup that forced a democratically elected president to flee the country at the threat of death and brought a government that is completely unacceptable to people in those regions of Ukraine - in Donbass over 90% of people speak Russian as their main language, they do not want to be forced to speak Ukrainian and worship Western Ukrainian ww2 Nazi collaborators like Bandera and Shukhevych.. So they started a rebellion and Russia was forced to intervene - otherwise it would be a treason of its own people. An analogous situation would be if the French speaking part of Canada tried to violently impose its identity over the rest of the country. If the Anglo-Candians then rose in revolt, wouldn't it be legitimate for US to intervene militarilu?

    Ukraine and Russia

    Belarus is not terribly stressed by Russia's presence. Kazakhstan and China aren't either Finland probably isn't either. A big % of Ukrainians probably aren't either - in USSR times Ukrainians and Russians (except Western Ukrainians) were considered practically one nation (like English and Scottish people), milions of people moved between Russian and Ukrainian SSR without any issue and they still do - for a matter of fact, 4 out of 8 leaders of USSR were ethnic Ukrainians.
