Post memes here.
A meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme.
An Internet meme or meme, is a cultural item that is spread via the Internet, often through social media platforms. The name is by the concept of memes proposed by Richard Dawkins in 1972. Internet memes can take various forms, such as images, videos, GIFs, and various other viral sensations.
- Wait at least 2 months before reposting
- No explicitly political content (about political figures, political events, elections and so on), !politicalmemes@lemmy.ca can be better place for that
- Use NSFW marking accordingly
Laittakaa meemejä tänne.
- Odota ainakin 2 kuukautta ennen meemin postaamista uudelleen
- Ei selkeän poliittista sisältöä (poliitikoista, poliittisista tapahtumista, vaaleista jne) parempi paikka esim. !politicalmemes@lemmy.ca

My current research is about pfas and how bad it is. You wanna know yhe most fun part? It probably is in your drinking water. Current testing methods are only for specific compounds and many manufacturers just use a slightly different chemical structure, whose effects can be the same in a biological system...
Can you share the negative health effects of ptfe consumption? I would have assumed that it would be inert in humans considering it's extraordinarily inert properties. Obviously it breaks down at temperatures over 315c, but that's not really relevant with ptfe in the water.
It doesn't seem to be the PTFE themselves, it's the molecules released when it eventually degrades due to fire, time or mechanical force; particularly PFOAs, which were at one point so widely used you can now find them everywhere. As well, they are still used to manufacture non-stick pans, just at an earlier step in the process so they are still present, but at 'safe' levels; however, if a non-stick pan is overheated, the coating almost instantly breaks down and releases unsafe levels of PFOA after that event.
Purchasing non-stick cookware is supporting companies that create, ship, and use PFOA which further degrades the environment and contaminates water.

My research is currently with pfoa and its ability to interfere with ttr proteins ability to transport t4 and t3. If you need a source just google pfoa calux.
Thanks for your work. (☞ ͡° ͜ʖ ͡°)☞
