I really don't know about food safe. Or safe for any end consumer, really. They absolutely need to do some severe toxicity testing. Because this funny new glue is an organic phosphate which in itself already raises some serious questions. On top of that, the ring also contains two perfluoropinacol moieties which could be released e.g. on heating or through interaction with acids or something else. This is a highly volatile molecule and "fatal in contact with skin," i.e. of the highest toxicity class. That ain't no good.

If it has a concept of data sources and can digest them, sure. Anecdotally, most issues with Excel at my job are caused by data sources being renamed, moved or reformatted, by broken logins, or by insufficient access rights.

Probably more for repairing than producing, in my experience. That stuff's expensive and breaks easily. An old lab joke: Which daily sound scares a chemist the most? - Krk.

One of my elderly colleagues once told me that at the end of each day, they'd put all the lab coats in a big vat of benzene to clean them. The next day, they took them out, let them dry for a short while and then just put them on again. I think it was in the early 80s? He did develop cancer later.

Sweet? I'd rather liken it to period blood, but more metallic and kind of... vicious. Its smell is hardly comparable to its relatives xylene, toluene, ethyl benzene.

Pure silica? It's really just SiO2. It might kind of fragment/ burst if it has a lot of water absorbed and you heat it too fast. Then everything in the vicinity would get sprinkled with fine dust which you shouldn't inhale in large quantities, as it might cause silicosis.

Yeah don't. Like many metals, finely dispersed iron can self-combust on air. I'd suggest an air-tight packaging filled with CO2, or, if your food is susceptible to acid, N2, if at all feasible. Industry uses additives similar to hydroquinone, mixed directly into, e.g., plastics. Plenty of them are food-safe, but I wouldn't know where to buy them if you aren't a business.

You can see for yourself: https://bundeswahlleiterin.de/bundestagswahlen/2025/ergebnis... This shows the winners of the "second vote." Dark blue = CSU (conservative party), its outlines are identical to Bavaria because this party only runs there and, this time around, won 100% of the second votes. Cyan = AfD, far right-wing party. Its outlines are nearly identical to the borders of the former GDR. Gray = CDU, CSU's sister party, making up for most of the remainder.

I hardly noticed, and I've been on Lemmy for nearly two years. I think it depends on which instance you sign on to. But a) you can filter out certain topics, users and even entire instances from your feed, and b) you can always sign up to a different instance if you still feel annoyed for whatever reason. For example, I left lemmy.world when it turned into some sort of Reddit clone.

European LNG spot market prices went up by much more than an order of magnitude between Summer 2020 and Spring 2022. They also went up for other regions while Russia has no problems selling gas outside of Europe, even with steep mark-ups. It pains me to write this, but Russia is coming out on top because of Europe cutting itself off from her gas.

I've been in the field for many years and I see the EU on the forefront of public chemical safety, both in terms of legislation and enforcement. ECHA is transparent about glyphosate [1]. It is not even labelled as CMR on REACH Annex III [2], and that's saying a lot. If you follow the developments, you will find that there is no way to prove a chemical as "safe". All it takes is one bloke on record to develop any health condition which can be linked to a chemical, and it will be scrutinized six ways to Sundays. Often leading to the introduction or decrease of an OEL, or a classification of this substance. As new humans are born all of the time, and diagnostics and analysis methods are still being improved, the likelihood of any given chemical to be "harmless" asymptotically approaches zero. 1 in 2 people develop cancer during their lives [3]. There are currently > 23000 chemicals on the EEA market at >= 1 t/a [4].

Where I live (EU), lawyers have standard rates for standard stuff. For a run-of-the-mill letter, you're looking at ~ 100 €, but could be 50 if they want to get you as a new customer. Source: A lawyer asked me whether they should write a legalese letter to someone I was planning to sue (work-related) with their help, and explained to me all of this, plus a lot of stuff I had to stress/ watch out for. I knew I had found a good lawyer when they then told me I could also have a go at writing it myself.

Now whether or not the example at hand counts as run-of-the-mill, I don't really know.

It is now assumed that this already happened, in 2011, in a Bulgarian umbrella attack in Germany's crime capital, Hanover. My somewhat unfounded guess is that the perpetrator himself perished not too long after the victim, which would explain why the case is still unsolved.

It's a nice step in the right direction, for sure. But, having worked paying jobs in both Chemistry and Product Safety: Not counting latex, nitrile is the bare minimum, really, when it comes to chemical resistivity, and it cannot handle heat (> 40 °C). But hot surfaces are very common in labs. Hands off of latex gloves, though! Not only are they no good against most chemicals, they can fill up like a sponge and soak your hands with them.

I actually had a similar type of dreams as mark_l_watson when I took quantum chemistry (that's not a drug... for most people). Since I switched to performing more mundane tasks for a living, my dreams shifted to me hopelessly trying to navigate the very real, although warped and endlessly labyrinthine, dim interior landscapes of my university's library which I last visited more than 10 years ago. It was built around 1970 and it is a kind of trip during waking hours already.

>Is reddit really in decline, though? Doesn't seem like it. In fact, arguably things improved a lot in the past year.

That depends on your quality metrics, and, of course, personal taste. To me, the continuous branching off of more and more arcane subreddits means two things:

- Your own voice bears more weight as the new arena is smaller at its inception

- The overall quality of discussions is getting blander as not every tiny niche sub can keep ace thinkers

So it appears that you can't have it both ways - fostering a great discussion atmosphere where, at the same time, every voice will be equally considered.

>Doesn't sound like it's either abnormal or volatile.

The WTI price drop was the 3rd largest in 20 years and briefly saw prices return to a level from 18 years ago. I couldn't have predicted that.
