The post clearly says that they also provide services to poor people and just adds it at the very end. I get that you are primed to reading this wrong but in this case it actually isn't wrong...

Your comment is based on a causal fallacy. Don't be a prick.

I was curious as well and in this article the only mention of dangerous bases is tert-Butyl lithium ("t-BuLi is very pyrophoric, it readily reacts with air catching fire, that’s why it has to be handled and stored with very special care, always under a protective inert atmosphere of pure nitrogen or argon"). But in that case you couldn't just drop it on the ground outside of a vent?

Maybe it also has to do with the human anatomy? Like, when people are thinking they probably have their mouth closed and maybe even purse their lips. The sound you can make in this pose is really just hmm I guess.

OK yeah, the next question would then be why we use certain facial expressions...

I asked mydelf the same. I guess you can only x-ray the brain by itself when it's not enclosed in the skull? So this should be the best resolution when scanning a living human.

Well, it's not that easy. Many plants have both female and male flower parts or flowers. And even if a species has individuals with only one of both sexes, then it might change over the season or over age. So there is really no way around pollen...

Maybe you could get into speedcubing ;)

If you turn this upside down and squint a little, you get the skull from the image above!

I've been using two different (refurbished) Pixel phones with CalyxOS for over 3 years now. It is a really great experience :) And the photos the phones can take are great, too!

Indeed, basic plant morphology knowledge plus some local Floras and iNaturalist worked out quite well for me in the tropics. There are also so many people that know plants on iNat. You only get into trouble if you try to ID rare species, but that's also the case in the temperate zones.

Typical trees belong to a group of plants called dicots

Whaaaat? Swiftly ignoring all gymnosperms? The temperate zones are full of trees that aren't dicots, or even angiosperms! Focusing on some biological traits that aren't crucial to the definition of a tree sounds like the author already likes their neat categories and wants to retroactively justify them...

Indeed, it simply is not a phylogenetic categorization but a physio-ecological one. Tree, like shrub, liana, herbaceous, woody/non-woody are all terms solely used to place plants into functional groups based on how they grow. None of these has to do with their taxonomy.

So the question is, what is a tree and is having secondary growth necessary to be one? Because monocots, like palms are, don't have secondary growth, they use some workarounds. But why should that matter in the definition of a tree? I don't know. So yeah, a coconut palm should be considered a tree. But it hasn't got to do with phylogenetics (like explained in the article you linked).

Also, millennia ago there have been vast forests of lycopods!! Just imagine huge trees that are actually spikemosses. So why shouldn't a palm not be a tree?

There are many other instances of doubled genus names in different Phyla, e.g. Polyura, Heteropsis, Ponera

Clopen is a really cute word!

The mushrooms from the bolete family here in Germany often stain blue (or some other color) when bruised but most are very good mushrooms for eating. For example, Imleria badia, Neoboletus erythropus and Suillus grevillei. The last one is even slimy but you can just remove the cap. (There is also this really tasty gill-having mushroom Lactarius deliciosus that stains green). Also, Armillaria can do bioluminescence but are also edible! I agree with checking for fungi infections of mushrooms and to learn to ID the deadly poisonous Amanita species (funnily enough, there are some really good edible ones in the same genus!).

Your guide to carefully test foraged organisms is definitely helpful. However, when foraging mushrooms you have to keep in mind some additional things. Many, if not most mushrooms are really toxic when eaten raw! People frequently get poisoned while eating edible mushrooms that are not cooked enough. They apparently often contain hemolysins. Also, there are a few tasty mushrooms that can be toxic if eaten in combination with alcohol. If you go foraging mushrooms, better try to learn some groups, how to distinguish them and what are their characteristics than trying to test by your body's reaction. But yeah, if you were to be without any food in the wild maybe it helps to know how to test for edibility.

Many trees can regrow quite drastically when cut back. Even stumps resprout in various tree species. But fungal infections can really take a toll on trees, so any wound is certainly a risk. So there is some truth to the meme, it is just hyperbolic.

Yummy!!

Wow, those conditions sound so incredibly harsh! Must have been such a phenomenal feeling when they've arrived and even broken the world record :)

Hard to spot and people might take it at face value.

What? That shouldn't be any basis for consent! Only if someone is able to consent, i.e. emphatically say 'yes' (or otherwise agree), should you start thinking about doing anything sexual involving them. If you do anything sexual involving someone who cannot say 'no' then that is a sexual violation of them.
