>> ... 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.

There'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.

Actually 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.

Also a key takeaway that brain drain is real and incredibly destructive for any underdeveloped country.

As 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?

I believe this is part of it https://arxiv.org/pdf/1608.06344v4.pdf
