Uni. of Alberta researchers solve puzzle that baffled scientists for decades
- the_duke 10y agoAs per usual for mainstream scientific articles... shallow, lot's of hyperbole, very little info... Does anyone have a better source for this? Maybe a link to the paper?
- nullpage 10y agoI believe this is part of it https://arxiv.org/pdf/1608.06344v4.pdf https://arxiv.org/pdf/1608.06344v4.pdf

- mattnewton 10y ago>> ... it was post-doctoral fellow Moe Rashidi, who immigrated from Iran, who deserves the credit. >> "He really did all the brilliant work,” Wolkow said. “Tremendous people are drawn here … and become fantastic new members of Canada.” That was one of the key takeaways here, a reminder of how important skilled immigration is to any country. That patent is owned by Canadians now.
- muninn_ 10y agoSkilled being the key word
- GFK_of_xmaspast 10y agoUnskilled immigrants of today are parents of the skilled natural-born citizens of tomorrow.
- nostromo 10y agoIt's quite difficult to immigrate to Canada as an unskilled immigrant.
- vinay427 10y agoUnless you're in need of a country to safely live in and qualify as a refugee, in which case Canada actually tries to do its part to house you.
- dmix 10y agoSkilled parents are more likely to have skilled children. Even ignoring any possible hereditary intelligence correlation that might exist, having good job prospects will naturally heighten the chance of their children doing well. There are also more than enough skilled people waiting to come here. With a backlog of skilled works the west has the opportunity to be selective (refugees are another subject). I personally support the idea that they should be more open to skilled workers. Although Canada already does a pretty good job compared to the US. Apparently the UK is looking into copying Canada's policies following Brexit. But even here in Canada skilled immigrants often get associated with unskilled or illegal immigrants, or just generally misunderstood in terms of the value they bring, which (unfairly) puts pressure on reducing numbers.
- iopq 10y agoNot necessarily. They could just be stuck in a cycle of poverty and be a drain on the system.
- msie 10y agoWell, there are no guarantees but Canada's education system increases the probability of skilled offspring.
- iopq 10y ago[citation needed] I went to school both in the United States and Ukraine and while the United States educational system was way more funded, it was not any better. So what if we have a TV in every classroom? Is watching educational movies a better use of time than getting a lecture from the teacher about it?
- slavik81 10y agoThere's a surprisingly large number of Iranians doing great work in Canadian universities. I'm not particularly well-versed in why, but it seems that smart people have both means and motive to emigrate.
- rossng 10y agoIran is a pretty highly-developed country with a population of 83 million people, so I don't think that's too surprising. There's a perception gap due to the western world's treatment of Iran. Maybe we shouldn't have overthrown their government and installed a dictator in the 1950s.
- stuxnet79 10y agoCan confirm this, and this spans all fields of study. They are doing great work. Canadian universities are choke full of immigrants of all kinds though (I'm one).

- yichi 10y agoActually Canada is a weird one when it comes to immigration. Work based skilled immigration to Canada is certainly easier than the US. But if you want to marry a Canadian and want to move to Canada as an American citizen, you have to wait 2 years for the visa to get approved, and there is no fiance visa or anything to speed up the process.
- kspaans 10y agoWorking on a spouse visa right now for me spouse, so I've got a slight clarification. As the non-citizen spouse of a Canadian you can VISIT (possibly by applying for a visitor visa like a normal tourist) and probably get that visitor visa extended as many time as you like while you wait for the Permanent Residency application to finish (average 2 year processing time). But you may not be able to work in Canada while you wait (there was some news about temporary work permits being issued to spouses who were inside of Canada while waiting for their PR).
- nightcracker 10y agoAlso a key takeaway that brain drain is real and incredibly destructive for any underdeveloped country.
