Medical Conspiracy Theories Popular in USA

My opinion:  I think the main thing that might be driving these theories forward is fear.  The medical landscape is so full of mysteries that people are likely to believe in one conspiracy theory or the other, especially if it is already quite popular.  It may also be driven by anger against the waning healthcare system in general.  I wonder how much research people do into conspiracy theories before they believe in them, and, if they actually have done research, how credible is it?  I wish the authors of this study had accounted for this and asked for a potential cause in their beliefs.  They could at least find out if these beliefs were inherent or not by asking how long the respondent has seriously considered such a theory.  This way, if the respondent indicates that they developed their belief recently, it is clear that a there must be a cause for this and the belief is not inherent.  Lastly, on another note, I wonder if this data isn't accurate because it was done through an online survey.  Are people without easy internet access more likely to believe in conspiracy theories because they cannot view scientific research?  Feel free to give thoughts and/or comments.

Half of Americans believe at least one medical conspiracy theory, study shows

"Our data suggest that medical conspiracy theories are widely known, broadly endorsed, and highly predictive of many common health behaviors."

March 19 (UPI) -- Do you believe that vaccines cause autism or that GMOs are being used to shrink the world’s population? Or that the government is preventing access to alternative medicines to benefit Big Pharma? That the government knows cell phones cause cancer but do nothing to stop it? That water fluoridation is suspicious? Or that the CIA infected African Americans with HIV?According to a study released Monday by researchers at University of Chicago, some 49 percent of Americans believe at least one of these medical six conspiracy theories to be true.
The study, published in JAMA Internal Medicine, questioned 1,351 adults in an online survey, asking whether they have heard of each of the above theories and whether they agreed or disagreed.
The survey also found that people who believed in conspiracies were more likely to seek out alternative medicine, with only 13 percent of nonbelievers taking herbal supplements compared to 35 percent of conspiracy believers.
Among those who believed conspiracies, 35 percent identified as liberal and 41 percent identified as conservative.

Scientists Capable of Making Artificial Vaginas

My opinion:  I know this seems kind of silly, but its importance cannot be underestimated, especially for others organs that may be grown in the future.  First off, this just goes to show that there may be more to a body part than meets the eye, suggesting that replacements are complicated to make.  However, now that this is made, I'm wondering if the same thing can be done except for male body parts.  What's more, doctors may use this method for sexual reassignment surgery.  Some downsides are that we don't know how these body parts will work in the future.  What if they're easier to break or malfunction as the body grows older?  Nonetheless, this is still a remarkable achievement and it seems to be working well as of now.  Feel free to give comments.

 Scientists grow viable vaginas from girls’ own cells

Eight years after they received implants, four young women report they have functioning sexual and excretory organs
Four young women born with abnormal or missing vaginas were implanted with lab-grown versions made from their own cells, the latest success in creating replacement organs that have so far included tracheas, bladders and urethras.
Follow-up tests show the new vaginas are indistinguishable from the women's own tissue and have grown in size as the young women, who got the implants as teens, matured.
Two of the four implant recipients, who were born with a working uterus but no vagina, now menstruate normally.
It is not yet clear whether these women can bear children, but because they are menstruating, it suggests their ovaries are working, so it may be possible, said Dr. Anthony Atala, director of Wake Forest Baptist Medical Center's Institute for Regenerative Medicine in North Carolina.
All implant recipients also reported that they are sexually active and satisfied with their arousal and orgasms, according to a press release from The Lancet, the medical journal where information on the implants was published Friday. They report no unusual pain.
The feat, which Atala and colleagues in Mexico describe in the article, is the latest demonstration from the growing field of regenerative medicine, a discipline in which doctors take advantage of the body's power to regrow and replace cells.
