While we are used to associate "the observer effect" with particle physics, it can appear in biology and/or chemistry as well. Keeping things meticulously clean on the microscopic level is a complicated task. One of the many reasons why so few EUV chip fabs even exist.

By that same effect we probably introduced life on Mars already.

It’s not improbable that some micro organism might have escaped the safety protocols. The likelihood it is still alive is low

Classic. This is like that female serial killer in Europe that turned out to actually just be DNA from a woman making the DNA collection swabs.

Plot twist: the woman making the DNA collection swabs was the serial killer.

So basically the gloves that kitchen staff now must wear means we get an extra dose of micro plastics? Yikes.

It says similar. “ Stearates are salts, or soap-like particles. Manufacturers coat disposable gloves with stearates to make them easier to peel from the molds used to form them. But stearates are also chemically very similar to some microplastics, according to the researchers, and can lead to false positives when researchers are looking for microplastic pollution.” Stearates aren’t microplastics. Maybe we need to be…

I'm still not aware of any reason to worry about micro plastics. As far as I know they seem harmless?

Not even that! This study doesn't even say contamination is causing overestimation. It says that it's possible. But as mentioned elsewhere in the thread, everyone knows that it's possible and take measure to mitigate it. A paper that said those mitigations were insufficient or empirically found not to work would be interesting. A paper saying "you should mitigate this" is... not very interesting.

> Not even that! This study doesn't even say contamination is causing overestimation. It says that it's possible. From the article: > They found that on average, the gloves imparted about 2,000 false positives per millimeter squared area. I dunno, that seems like a lot of false positives. Doesn’t that strongly imply that overestimation would be a pretty likely outcome here? Sounds like a completely sterile 1mm^2 area…

The way you mitigate this is by using negative samples. Basically blank swabs/tubes/whatever that don't have the substance you're testing in it, but that is handled the same way.

Then the tested result is Actual Sample Result - Negative Sample Result.

So you'd expect a microplastic sample to have 2,000 plus N per mm^2, and N is the result of your test.

It is true that there is not currently conclusive proof that micro plastics are a significant risk to human health. However, this is the same line the tobacco industry used for decades even though they knew different.

I think any time a new material starts to meaningfully accumulate in our bodies, our food sources, our oceans, etc, we should at least go with caution. The default stance should be caution, not fearlessness.

It is partially correct. Except make sure you have the necessary skills to question the science. Intuition in these things are quite misleading. Don't start questioning cancer reports just because you don't feel sick.If you really don't trust it, get a relevant medical degree or take second opinions from those who are really qualified and not some quacks. Otherwise you would just end up dead.

The problem with your claim that the plebs are incapable of research because they don't have equipment and are dumb is the wholesale erosion of belief in institutions after the COVID "vaccine" situation

I reject the scare quotes you're putting around the word vaccine.

The COVID vaccine is a triumph of human ingenuity and we should all feel incredibly proud it exists. It was the moon landing of our time.

More broadly, vaccines have probably saved more human lives than any other medical technology in history.
