  • I’m a microbiologist but my grad school work, research, and coursework was very chemistry heavy. There are no “probably does somethings” of significance here: the chemistry of plastic generation is extremely well researched.

    Plastic is made of polymerized hydrocarbons, linked up identical tiny units of carbon strands called monomers. Polymerization, the linkage of the monomers into a polymer, requires the use of a catalyst. This is often done with increased heat and pressure to increase the speed of polymerization. Maximum temperatures are around 350°C for certain plastics but are more commonly 140-160°C as higher temperatures can cause the material to break down. Once the desired size of linkage is created, the polymer is capped to keep it from growing further.

    Polymerized hydrocarbons degrade, not further polymerize somehow, at high temperatures like 600° C. Saying there’s some mysterious, high-heat-driven polymerization is like saying burning wood, which is largely a polymer of glucose called cellulose, somehow creates more cellulose as it burns. The burning is due to the release of the energy contained in the bonds in the wood as they break down and react with oxygen.

    Even if the process DID somehow create some plastic, a given mass of brain tissue would be expected to create predictable amounts of this mystery polymer, giving a background measurement that can be subtracted. Again, though, we know how this all works so it’s not really a concern.







  • I’m a Washingtonian and I’ve voted, protested, and in every way possible fought against politicians like this for decades.

    This isn’t the classic United States “fucking over other countries for US gain”. Trump and the MAGA cronies are also fucking over the US for personal gain. They’ve fooled the most gullible, ignorant fraction of the population into supporting them despite it being against their best interests, a fraction that continues to grow due to decades of intense propaganda, sabotaged public education, and political cultism.

    We’re all victims here. Some more than others but, with the exception of those supporting the fascist MAGA movement with full knowledge of what they truly stand for, everyone in the world is a victim.





  • I’m learning more by the day that .world’s issue with tankies is driven less by any of their actually problematic behavior than by this growing pseudo-mythos where users seem to treat them as a sort of online bogeyman. More often that not, I’ve seen “the tankies sure are going to hate this!” where no actual tankies ever appear. It’s just lazy engagement, plus “tankies” becoming Lemmy-speak for “leftist who I disagree with (or challenges my preconceptions in a way that makes me uncomfortable)”.

    Checking out the comment thread, as of the time of this writing, I see one “but US bad too!” moron, a few .ml users with fairly reasoned responses (regardless of if I agree or not), and a few geniuses, including the OP there, looking to start shit and acting surprised when they’re called out on it.
