@beehaw.orgThere's a light next to where i used to live that, like you suggested, used the flashing to indicate when right turns were allowed. I liked it especially since there was a lot of pedestrian traffic during the day but basically none at night (and was thus able to handle the different needs of the road depending on time of day), and it was a really intuitive way to let drivers know what the pedestrian signals were doing. Best part was it was for a right-turn-only lane, and had flashing-yellow (no green at all) to remind you to check for pedestrians and bikes.
I saw The Fellowship of the Ring nine times in theaters. Once i hit time #4 or #5, I realized i had to keep going until I could say i saw it once for each member of the fellowship.
For real. I got some curry powder recently that said it may cause reproductive harm. Apparently tumeric can have enough heavy metals in it to cause issues if you eat absurd quantities of the stuff everyday for your whole life.
But i don't live in California, so i think i'll be ok.
I really don't think you have anything to worry about. The plastic these little guys eat needs to be partially degraded and broken up into smaller pieces for them to make any meaningful digestive progress. It's exceedingly unlikely the bacteria themselves are going to get efficient enough that your non-waste plastic stuff is in any danger. More likely, the enzymes themselves will be used as part of a larger controlled industrial process (enzyme recapture is important to staying cost effective after all). Even if that wasn't the case, these bacteria are suited for life in a landfill, not in your pipes.
We should at least start by closing the stepped-up basis loophole, but stopping there would require patience that i don't have.
Except it doesn't hold up in the elements all that well, though (at least in a form that is still usable, the plastic is still there, just in little pieces and/or without the desired structural integrity). Plastics degrade when exposed to sunlight and oxygen (photo-oxidation). Combine that with mechanical action of waves, and now you have a bunch of little plastic bits floating in the ocean that are even harder to clean up (but easier for the bacteria to eat!). A glass or metal bottle will hold up much better than a plastic one, over a long enough time period.
But they even break down when exposed to temperature cycling and mechanical stress over long periods of time. I'm sure you've also noticed old plastic food containers, get harder and harder to clean and start getting cloudy: that's the plastic breaking down and micro-fissures appearing on the surface, thanks to repeated exposure to dishwashers, freezers, and still-hot leftovers. Once again, a glass dish is gonna hold up much better.
They have to use special additives for plastics intended for long-term outdoor use (the additives are like sunscreen for plastic, they absorb the UV so that the plastic doesn't) to combat these reaction pathways. And I'd bet money that if plastic-eating bacteria end up becoming a problem, there will be additives we can use to discourage them for appropriate applications.
But you'll notice that in the case of plastic in landfills, there's no UV light from the sun, basically no oxygen, and any mechanical stress or temperature cycling isn't enough for fast breakdown of the plastic polymers. These conditions are also very different from, say, your kitchen counter or hospital storage rooms. If the plastic-eating bacteria prefers the landfill habitat (or literally cannot thrive in any other environment -- which is not an uncommon phenomenon; in the article, they mention difficulties culturing bacteria for study in a lab environment), then we have a perfect tool for breaking down landfill plastics that won't impact in the slightest the plastics things we want to keep. Similarly, the kind of bacteria that could be useful for ridding us of fishing lines and nets floating around in the ocean would most likely not be well suited for non-aquatic environments.
For me, the vaccine seemed to prevent catching the first few variants quite well, but i eventually caught the Omicron (probably, idk for sure) variant. My SO showed symptoms first, and neither of us tested (nasal swab) positive until ~24hrs after symptoms appeared.
I will keep it there for future historians.
great, now i have spit coffee all over the place. thanks for the laugh!
Came here to tell the same story. They used to play some crazy shit on TLC before the reality show takeover.
