Are you saying CNN is government approved propaganda? I thought that was Fox and OAN? Color me corrected. Like researching for a paper, the best strategy is to use more than one source. I highly suggest you do the same when gathering news. Even consider sources such as the BBC for US news.
No... peer-reviewed articles are in journals--many medical or academic journals. Research is not just a couple of people in a lab poking at rats. It is collaborative studies in labs and in reviewing and dissecting others research and conclusions. I edited a dental article once that was disagreeing with an research article about a procedure and laid out the calculations and equations as to why the procedure would not work. Research is a lot of math, logic, interpretation, and poking at rats in labs. It is also testing drugs on cells in Petri dishes and monitoring and reporting the data. Pharmaceutical companies develop drugs based on research, but they do not do the research. Those are two different beasts. Something you are not considering as far as not curing is that doctors prescribe drugs, not the drug companies. There are also diseases that researchers have not been able to find a cure for--cancer, AIDS, diabetes, etc., but they do have drugs to battle and/or contain them. If people were perfect and could solve all your problems, they would be Gods.
Are you under the impression that the president is the government? For that matter, do you really believe that Fox News is pro-Trump, or even that Trump is conservative? If so, you need to take your own advice and quit restricting your "research" to CNN and MSNBC. Watching the news on television or reading a newspaper is pretty poor form of research, anyhow.
You can not do research from the main street medial because they are all controlled by six groups who do not have your interest. Like they all claimed weapons of mass destruction in Iraq but there was not Trump and Russian collusion and there was not Syria gassed its own people CNN&, MSNBC said they were not allowed to go there but OAN when there and interviewed the people there and even talked to the doctors only to find it was all BS. Peer reviewed in medicine is a joke even the retired editor of Lancet which is one of the top medical journals said over half are fraudulent. As far as cures the medical system stopped making cures in the 1950 and now the manage, control,and treat disease. Why do ND have their patents become free of type two diabetes, high blood pressure and arthritis. Because the cure people but the FDA has co op the word cure and they can not use it.
