Pandemimimetics


Tracking Facebook connections between parent groups and vaccine misinfo
Jan 2022, Ars Technica

A recent analysis of the network of vaccine misinformation finds that most of the worst misinformation sources are probably too small to stand out as being in need of moderation. The analysis also shows that the pandemic has brought mainstream parenting groups noticeably closer to groups devoted to conspiracy theories.

These researchers are special, because they were already doing vaccine misinformation network analysis before the pandemic. 

They use the most basic of network analysis tools, ForceAtlas2, to look at how groups connect to each other via likes of each other's group-page. Groups were also categorized as pro- or anti-vaccine, or neutral.

Here's some things that were true both before and after the pandemic started:
  • Pro-vaccine groups are double the anti-vaccine groups
  • Pro-vaccine groups are strongly connected to each other, but less connected to neutral groups
  • Anti-vaccine groups are also strongly connected to each other, but also more connected to neutral groups

But here's what happened during the pandemic:
  • Anti-vaccine groups became more closely connected with alternative medicine in general (think reiki, homeopathy, and circadian rhythms...just kidding, circadian rhythms used to be conspiracy theory, but now less so)
  • Alternative medicine is strongly connected to other conspiracy theories, like 5G or Fluoride in your Water
  • Alternative medicine is also strongly connected to parent groups
  • Anti-GMO is the most "in-between" the whole network, bringing together all the different groups into one massive supercluster of memetic evolutionary pressure.

So we have Alternative Medicine at the nexus of the pandemic-misinformation-network connecting parents to anti-vaccination groups. 

The rest of the article is about how Facebook failed to moderate misinformation on their network, and how, and what they can do better, but we're not really interested in that are we.

New technique, effective in mice, could help advance the use of probiotics

It sure looks like probiotics are good for us. The problems is they get destroyed by our own stomach acid.  So scientists designed a special protective envelope that helps the probiotics stay around long enough to do their thing in our digestive track. 

Would it be funny if eventually they eventually design it to be just like regular food?

After two hours, sunscreen that includes zinc oxide loses effectiveness, becomes toxic
Oct 2021, phys.org

The older you get, the more you realize that almost any product which claims to have health benefits almost never does, and is actually causing as much problems as it tries to solve. I don't really blame anyone, because the human body is too complicated, and we'll never fully understand it. In this case, they added zinc because it's supposed to be better at blocking sun, which it does, until it doesn't, and then it actually facilitates reactions that make the rest of the ingredients toxic. Sunscreen is a market worth $24 billion.
