A 50-year-old scientist from North Korea who mysteriously disappeared when nobody could replicate his results
A single South Korean scientist from 2016 who has his name on the handful of research showing positive results in this area.
MAYBE the guy fled from North Korea and has now a new identity in South Korea.
Damn I have no idea why I didn't realise this... Though, the Kwang guy must be pretty damn old by now if that's the case...
