B Radio waves -- Tissue Refractive Index

Click For Summary
The refractive index (RI) of tissue is approximately 1.4 for light but decreases at lower frequencies, with estimates for radio waves (1 Hz - 1 MHz) suggesting an RI range between 3 and 10, depending on the relative permittivity (Er) of the tissue. The dielectric constant of water is about 80, but living tissue's Er is typically reduced to around 25, leading to a calculated RI of about 5. The discussion highlights the challenges of using radio waves for imaging or influencing biological tissues due to their long wavelengths, which may not effectively interact with smaller biological structures. There is interest in using electromagnetic waves to influence macromolecules, but the complexity of identifying resonant frequencies and the potential for dielectric heating are significant concerns. Overall, the interplay between electromagnetic radiation and biological tissues is intricate and requires careful consideration of frequency and tissue properties.

I think it's got to be even harder than that.

First, DNA curls. So any "magic frequency" changes cell-by-cell depending on exactly how it's curled. Putting that aside, bacterial DNA looks like human DNA: the chemistry is the same. Only the content is different. You can't attack an A group to T group: you need a frequency that attacks the whole thing coherently. Figuring that out will be Real Doggone Hard, and building a transmitter that precise will be Real Doggone Hard.

Target the molecular chemistry of the transcription process. That is the only time you will see the internal sequence of the DNA or RNA going past during replication. You need gene scissors, not a microwave oven.

The references cited are wholley inadequate to support your claims.
Agreed.

@roxyboy -- this thread will remain closed. If you have a valid reference that you want to ask questions about, start a new thread and post links for the reference and ask *specific* questions about that reference. Please avoid making assertions at PF that are not backed up by the mainstream scientific literature.
