Some stand out takeaways: > We assessed how reliable current measures are for trying to find microplastics in blood. And what we found is that lipids and fats will give you a false positive for polyethylene. > We worked with an architect, and we built the lab pretty much from scratch. [...] So we ended up going with stainless steel. It was the only way to not have any plastics. > I don’t think we’ve got really good e…

Microplastics have always fascinated me, because I keep seeing article after article about how much microplastic exists around us, but far less strong evidence about its actual effects. That is not to say there are no effects, of course. Maybe we just have not found them yet.

A friend of mine worked on her bachelor’s thesis about the effects of microplastics on the immune system, specifically T cells. Her result was that the microplastic particles she studied were too large to interact with T cells.

She probably will not publish this result because she thinks it is not interesting enough. Classic file-drawer problem in academic science.

While I encourage her to do it anyways as a negative results is also interesting but she wanted results that are worthing of headlines in magazines.

I think hate of plastics is an emergent form of elitism.

Upwardly mobile middle/upper class people who've sort of "maxed out" the amount of personal identity they can buy with regular plastic things can unlock a new level of identity by deciding that plastics are bad for them and eliminating plastics from their life, a process which conveniently requires buying a whole new set of things that distinguish them from their peers.

This is the only way I can explain how irrational and inconsistent plastic-haters behavior is. There is so much invisible plastic in their life that they don't seem to care about.

I participated in research from 2017-2022 that found similar results regarding bio-interactions, generally.

Learned a lot about making microfludic flow cells at least

Even more so: plastics are not a specific chemical and they are not a specific material. Plastic is a category of materials that is very broad and very wide. You can make plastics out of almost anything. Therefore, to hate on plastics is to basically hate on an entire category of engineering and material design but not to actually know what a plastic is... sheer ignorance.

Can microplastics never get small enough to interact with T cells?

> requires buying a whole new set of things that distinguish them from their peers

No, it requires buying a whole new set of things to fit in with and be accepted by their peers, to distinguish themselves from the outgroup, the plastic users.

I don’t necessarily believe this is some emergent elitism; I see it more as a modern religion with many many rules about eating and consumption (using plastic is now a sin).

Like any religion, sinners (for example plastic users) are mostly pitied because they are ignorant, but those who know and choose to use plastic anyway, well, it’s OK to hate them.
