I like how we all now know that microplastics and PFAS seriously contaminate our water sources, but there's no real thought about things like nanotubes doing the same thing. Wonder what consuming carbon nanotubes might do to us.

Not the same but some people have experimented with C60 spheres. Apparently it is either very good or it increases ROS reactive oxygen species depending on who you ask and how it is prepared

400 billion market cap companies do not usually have 400 billion in liquidity laying around. And after the first bankruptcy there may now well be a second: https://www.reuters.com/legal/jj-effort-resolve-talc-lawsuit...

As I understand it that link describes a plan to use the bankruptcy of a subsidiary (NOT the main company) as a way to resolve the court cases in one go. The subsidiary is funded with enough money to pay the expected settlements (with the parent company guaranteeing any shortfalls) and bankruptcy is used here as a legal tool rather than a "we are out of money" point. Matt Levine had a great section about this in his…

That subsidiary is just a legal trick. And this is exactly what J&J want you to believe.

"business people" will pretty much only allocate resources to endeavors that are financially profitable for themselves and these same people quite often provide financial incentives to politicians who promise to advocate for policies that result in additional profitability for the business people regardless of the environmental or social consequences. Those elected politicians need to be replaced and the capacity for…

the above solution is silly expensive. Expensive doesn’t mean that somebody is greedy, it means that it takes a lot of effort from a lot of people - effort that could probably be spent more effectively.

Equating expensive with valuable, while very much in line with rules coming from Economics 101, is very questionable in real life in my experience.

I feel like we keep hearing about technologies like this that are going to change the world but none of them ever actually get implemented... just me?

I mean, this is like the moon landing — private companies can build the technology, but it's not going to get deployed at scale unless a government sponsors it, because there's not a clear path to profit.

And like, is congress going to spend $10B deploying this at scale? That would be great, but they can't even pass a budget.

I was wondering this literally yesterday... are there any current methods for filtering out microplastics? Currently I just have a filter within my fridge for drinking water... but I take it that doesnt do much

carbon filters do filter out quite a bit, but not all, so it's hardly "not much". A quick search will show you filtering down to 1-5um sizes

I guess it's not possible to design a tea bag that's not made out of plastic but that can also survive the boiling hot temperatures?

are tea bags even necessary? people managed drinking tea before plastic was invented

Are cars even needed? people walked before. Is any modern convenience needed? We can probably live in tents and use a bow and arrow to get our meals.

why do you need hot water?

Because it's far more effective at cleaning than cold water.

but tea doesn't really even need detergent? a scrub and rinse for the pot is fine.

Just transfer your tea out of the plastic tea sachets into a cotton filter. Coffee filter or they make small ones for loose leaf tea.

I would choose a different brand if the tea bags came as plastic and send them a nasty letter. I've been lucky enough to never have encountered them I guess.

Honestly I find some of the "nicer/high end" or even organic brands of tea sometimes use the plastic sachet, this is because that allows you to see the product inside whereas the other ones hide the product. The only brands I run across with it lately are Harney and Sons, and a Russian tea brand Maiskiy, but most Maiskiy bags are paper. And Harney and Sons is a nice treat.

Do you mean that they lied in their annual report about their profits and/or their current cash on hand? Or that the total legal costs will be much higher than the 9 billion settlement agreement?

Because I still don't see how a 9 billion settlement would bankrupt J&J, even if the subsidiary were to be reabsorbed into J&J tomorrow. They already set aside ~7 billion in Q1 2023 for this and have way deeper reserves available.
