Study of Cellphone Risks Finds 'Some Evidence' of Link To Cancer, At Least In Male Rats (nytimes.com)
An anonymous reader quotes a report from The New York Times: For decades, health experts have struggled to determine whether or not cellphones can cause cancer. On Thursday, a federal agency released the final results of what experts call the world's largest and most costly experiment to look into the question. The study originated in the Clinton administration, cost $30 million and involved some 3,000 rodents. The experiment, by the National Toxicology Program, found positive but relatively modest evidence that radio waves from some types of cellphones could raise the risk that male rats develop brain cancer. But he cautioned that the exposure levels and durations were far greater than what people typically encounter, and thus cannot "be compared directly to the exposure that humans experience." Moreover, the rat study examined the effects of a radio frequency associated with an early generation of cellphone technology, one that fell out of routine use years ago. Any concerns arising from the study thus would seem to apply mainly to early adopters who used those bygone devices, not to users of current models.
The lowest level of radiation in the federal study was equal to the maximum exposure that federal regulations allow for cellphone users. That level of exposure rarely occurs in typical cellphone use, the toxicology agency said. The highest level was four times higher than the permitted maximum. The rodents in the studies were exposed to radiation nine hours a day for two years -- far longer even than heavy users of cellphones. For the rats, the exposures started before birth and continued until they were about 2 years old. Some 2 to 3 percent of the male rats exposed to the radiation developed malignant gliomas, a deadly brain cancer, compared to none in a control group that received no radiation. Many epidemiologists see no overall rise in the incidence of gliomas in the human population. "The study also found that about 5 to 7 percent of the male rats exposed to the highest level of radiation developed certain heart tumors, called schwannomas, compared to none in the control group," the NYT reports.
It's worth nothing that the rats were exposed to radiation at a frequency of 900 megahertz, the frequency used in the second generation of cellphones that prevailed in the 90s, when the study was first conceived. For comparison, fourth generation (4G) and fifth generation (5G) phones employ much higher frequencies, which are "far less successful at penetrating the bodies of humans and rats," the NYT reports.

The confidence interval is 98%, sometimes 95%. That is, just by random chance, 2% or 5% of the time, a study will turn up a correlation which doesn't really exist. The die rolls just happened to come up snake eyes that time. The chances increase the more correlations a study looks for. Like the massive Netherlands study a couple decades back which found a strong correlation between cell phone radiation and certain types of cancer. But it turned out they looked at thousands of possible correlations, so just by chance alone you'd have expected them to find a few hundred random correlations, with a few "strong" ones (strong by chance, not because it was real). Like if you throw a thousand darts at a dartboard, just by pure chance a few will hit the bullseye; not because you're good at throwing darts, but because of random chance.
If (as the media tends to do) you then choose to publicize the studies finding a correlation while ignoring all the studies finding no correlation, then you're committing confirmation bias. Studies which find no positive result still generate valid data. And dismissing them in favor of studies with a positive result is a statistical and logical error. To properly assess what's going on, you need to compare the number of positive result studies with the number of negative result studies. And given the huge number of negative result studies, the greater likelihood here is that this is one of the studies which found a correlation due to a random blip, not something that's real.
Obligatory XKCD comic.
Talk about the deaths of little 21 month old Mariee, how ICE stole her from her mother, she got sick in an ICE internment army camp, lost 1kg of weight, was not given medical attention before being released to die with her mother, the mother who lives in New Jersey.
But Vice News says five pediatricians who reviewed details of Mariee's care say that after contracting the illness, she received treatment that was consistent with what they would have done. The story says all five doctors believed Mariee's "recommended course of treatment would have been the same had she not been in ICE custody."
"It's reasonable care," said Dr. Ewen Wang, associate director of pediatric emergency medicine at Stanford University Medical Center. "It didn't sound like she was in the best of health, but not something you anticipate dying from."

New Jersey.
"Juarez told Vice News that she decided to have Mariee buried in their native Guatemala. Her asylum case is pending."
Democrat propaganda in full swing.
