What is global news?

Something that happened or was uncovered recently anywhere in the world. It doesn't have to have global implications. Just has to be informative in some way.


Post guidelines

Title formatPost title should mirror the news source title.
URL formatPost URL should be the original link to the article (even if paywalled) and archived copies left in the body. It allows avoiding duplicate posts when cross-posting.
[Opinion] prefixOpinion (op-ed) articles must use [Opinion] prefix before the title.
Country prefixCountry prefix can be added to the title with a separator (|, :, etc.) where title is not clear enough from which country the news is coming from.

Isn't aluminum oxide really bad for people to inhale?

[–] FaceDeer@fedia.io 6 points 2 months ago (5 children)

Why do you say that? I just did some Googling and it appears to be basically as inert as you can get, it's just dust. The main concerns I saw were industrial environments where there might be a risk of the sheer amount of it causing problems via irritation of mucous membranes and whatnot. A windy day sweeping dust up off the ground would put far more into your lungs than satellite burn-ups would.

I had a friend who used to make ball bearings in a shop once. I thought a mutual friend mentioned it when he died.

Potentially zinc oxide, then, which is horrible for you.

Maybe. He's been dead since the early aughts, memories fade.
