This in itself could cause statistical group differences,” Della Sala said.<p><a href="https://nationalpost.com/news/world/scans-show-changes-to-brains-of-injured-havana-u-s-embassy-workers" rel="nofollow">https://nationalpost.com/news/world/scans-show-changes-to-br...</a><p>The microwave thingy is just so far-fetched. If such a weapon exists, wouldn't the US intelligence agencies already have developed it? Sounds implausible that China, Cuba, and presumably also former Soviet states, would have access to this super-sneaky microwave weapon but not the US.
