Okay just if you’re wondering, no it’s not a new color outside of the six or seven main colors but just an impossibly saturated green. The article explains that the retina has receptors for blue, green and red waves but that it’s impossible to see green without stimulating the blue and/or red one way or another. Their laser method manages to only stimulate the green receptors, so the shade of green that you see is impossible to be seen in any other way.

I didn’t know the topical ones acted that way. I thought they were more like a repellent. The oral ones, in my experience, are infallible. Give a pill to a flea infested cat and in thirty minutes by the clock you’ll start seeing the fleas jump out like they’re having a seizure. The cat will scratch for some twenty minutes or so. And that’s it. The tricky part is getting the cat to take the pill.

You mean oral, right? Oral pills against fleas and ticks poison the parasites through the blood they consume.

TLDR: “we don’t know”, says the article, “but we can hypothesize. Here’s a bunch of theories you probably already considered. But nobody did proper research on any. So go figure. Have you watched Severance tho?”

TIL there is a diffraction limit
