My opinion: what this really shows is that electro-magnetic waves/pulses have very broad beneficial effects, for a very, very, very wide range of electromagnetic parameters. This is a great example to support the fact that there is no one, single, secret, magical frequency. Almost anything will do within a very broad range of electro-magnetic parameters.
Think of it this way: PEMF is a lot like washing your hands when it comes to conferring biological benefits. There are a lot of ways to wash your hands, some work better than others, but if you follow a few simple guidelines, mostly it works pretty well. You do not need mystical water from some secret hidden spring, only drawn on a full moon, with equally mystical soap, applied for only a precise amount of time to get a good hand washing. And hand washing is not specific to one type of germ, and different styles of hand washing are not specific to specific germs. Some soaps are more effective against certain types of had-to-kill bugs, but even that is pretty broad, not specific.
In this same way, PEMF and electromagnetism can all be pretty much beneficial. So whether or not this research paper specifically supports Rife (or any other specific form of commercial PEMF) is not at all clear. Maybe, maybe not, probably unknown.
Add to this the KNOWN AND WELL DOCUMENTED FACT that about 80% to 90% of all biomedical research papers are not repeatable. That means, you should not put too much stock into any one report or finding. When it has been repeated, by different people, independently, in a different place… several times… then you can start to think it may be real.
But if you chase after every exciting scientific finding, you will run yourself into a circle, forever. And you will be disappointed forever, because most “exciting” scientific findings in biomedical research DO NOT stand the test of time. They are NOT repeatable. They are NOT real.
Everyone: before you spend any more time looking at any more scientific papers, I strongly suggest everyone get there eyes opened to the reality of biomedical research papers by reading the book:
Rigor Mortis: How Sloppy Science Creates Worthless Cures, Crushes Hope, and Wastes Billions. by Richard Harris (available on amazon)
