Essentially EM fields alternating in the low to medium frequency bands (~100khz-1mhz) can disrupt cell processes by physically jiggling the polar molecules that make up portions of miotic spindles/microtubules. Among presumably other things this effect is being investigated as a cancer fighting mechanism called 'tumor treating fields'.
The carrier frequency of mobile phones is obviously far beyond the range in question, but there could be signal modulation components that alternate RF power levels in this frequency range.
This is something that is already (or should be, in theory) rigorously tested for everything that's put on the consumer market (from your cheapest USB charger to your iPhone).
Realistically we've been beaming our brains for decades now without a glut of brain tumors, but we might just be getting lucky, and if we don't know what to look for it could bite us later.
The unfortunate reality is that the market is flooded with noisy devices, often cheaply produces overseas, that vastly exceed legal limits (chargers and other rectifiers, plasma televisions, powerline adapters, and much more).
Enforcement is difficult due to how widespread these devices are.
In many places, the noise floor is to high that long-range shortwave radio communications all but impossible.
There’s definitely an effect. It’s in clinical trials right now.
The fact that no-one talks about any of this just goes to show the extent of the lobbying done by the telecom industry.
If monsanto could do it, then others can too. I'm impressed by how quickly everyone decided that the scientific cover-up monsanto pulled off was a one-time event that couldn't possibly happen anywhere else.
Some people believe vaccines cause Down's Syndrome.
"Let’s be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus. There is no such thing as consensus science. If it’s consensus, it isn’t science. If it’s science, it isn’t consensus. Period." - Michael Crichton (https://tinyurl.com/vcxj2ex)
Appears to contradict
"What is relevant is reproducible results."
Aren't reproducible results a form of consensus?
Not in the least. "Reproducible results" represents the technical and methodological ability to confirm that an effect is real. "Consensus" is whether a political body is willing to admit that the effect is real.
And we all know politics finds truth to be...
> If 100 independent scientists reproduce results, those results themselves are a scientific consensus
Not in any sense that's relevant to the discovery of new information or its verification.
Other forms of scientific disagreement happen, but those disagreements imply different predictions, and can be resolved with more experiments.
Science is a process that bootstraps broad agreements (scientific laws) from very tiny agreements (observations). The fact that a broad agreement (consensus) exists carries no weight if one lone wacky scientist can show reproducible observations that contradict it.
The reason the scientific evidence is minimal is that we have been using simplistic models of human bodies for RF testing.
Often, this heat will be localized to where the antenna is located—I've noticed that my iPhone 8 will sometimes feel burning hot along its right edge, for example, and no amount of closing applications or disabling radios will cool it down. The only thing for it, usually, is to turn it off entirely, such that the baseband stops receiving power. (For some reason, upon turning it back on, it doesn't heat back up, even if I haven't moved—perhaps because the baseband's criteria for connecting to towers is stricter than its criteria for staying connected to towers.)
1.6W/kg is a conservative limit.
Oh and it's worth mentioning that everything around you at room temperature is emitting 400 watts per square meter of infrared. That's almost as much infrared as you get from the sun (1kW total, roughly 4% ultraviolet, 53% infrared, 43% visible).
And the thing to know about evolution and life is that life evolved to be robust in the face of changes and different environments.
They both carry energy that is turned into heat when absorbed by your body.

This is in contrast with ionizing radiation, which causes chemical changes to the materials of your body when it hits you. That kind of radiation is above the visible spectrum when made of photons, or made of different atomic particles
The iPhone 11 is 7 watt hours, so 25 kilojoule. Wolfram alpha helpfully tells me this is about the same energy as burning 0.64 grams of coal or 0.66 grams of human fat.
I downvoted you because this is incorrect. You're ignoring the skin's ability to dissipate heat. Brief exposure to high heat does not have the same effect as extended exposure to low heat.
I should be worried about the heat generated from my phone? I thought maybe there was some issue with RF and my cells, but this seems like a complete nonissue to me. Am I being foolish for writing this off? The only time my phone is going to burn me is if the battery explodes, which doesn't seem to be a pervasive issue. So probably not. As someone else pointed out this is a marketing ploy.
