@cicerone imposter,

There is no way for you to know that. The omniscience is unattainable and as a scientist, as you are presenting yourself to be, you should have known that.
I have noticed that there are a lot of scientists (and people presenting themselves as scientists) ... and also politicians, and their para-military servants that may know much more than you can possibly imagine for them to know. Besides that they may interpret the things in a lot of distorted ways.
Not all scientific reports are published. The greater part of the information remains 'for internal use only'. Almost nothing of the intra-corporate innovations and findings is published.
Very few of the reports of clinical trials, on medications for example, are published - most of them remain top secret in benefit of the pharmaceutical companies ... thus exposing at (unnecessary) risk the consumers and preserving the shamelessly high profits from the 'regular customers' flow ... and also in benefit of the guys from the psychotronics for 'security purposes' (whatever this might mean).
In 20 years, when the classification denotement is expired, the documents are scheduled for destruction (actually moved to another data storehouse, from where they can be used by anyone who pays the most). You don't even know how much of the information might have had such fate.
Hence, the much more honest statement would be 'I don't know' ... and 'if FM does not know it either, there is no way for any scientist to know it' (which would be an arbitrary statement made on the grounds of insufficient and incomplete information ... and incorrect assumptions). Anyway.
