Straight off AI; with a little tweaking. Up to Enders new methodology for 'isolating' a virus, the common method was to inject, into the brains of monkeys, some toxic filth. If the monkey died; that was 'proof', they said, that there was a killer virus in the injected muck. Enders used a different approach. He took gloop/puss from a 'measles infected' person and after adding various chemicals to his concoction, grew the mix in a petri dish. The stuff that was being grown, after being starved of nutrients; died. That was enough evidence, he said, to announce that he had found a virus. What is not so well known is that he did a control, without the puss/gloop from a measles sufferer. The methodology of the experiment was identical, but without the virus mix. The result was the same; death of the food. And he graciously said so in his paper. Not so widely spoken about is that. And of course, virologists since, don't do controls. Enders didn't isolate any virus. He simply brought a new method of procedure to the 'ologists' laboratory. And it violated the gold standard of lab work in that field. The first principle; isolate and purify the entity. One must ask; why don't the 'ologists isolate and purify the virus before doing their petri-dish experiments? Many of them have been asked. Some say the virus is too small. Some say there is not enough from one person. 'What about 100 people sick with the same virus?' No answer. Most don't/can't answer because there is no virus to be found, and they wouldn't want to be seen admitting that; would they. $$$ Nature is us. We are nature.
