Yes it seems insane to me that ivory from EXTINCT mammals that is mined out of sensitive permafrost (often causing severe environmental damage) is legal, but none the less, that is true. Read more in my latest for @ChemistryWorld:

Ancient mammoths and modern elephants lived in vastly different environments, so the isotopic signatures from their tusks vary accordingly. By looking at the hydrogen-2 and oxygen-18 ratios of ivory, we can tell what kind of animal it came from!.

The trade of elephant ivory is illegal in most countries. MAMMOTH ivory however, surprisingly, legal!.How do we differentiate legal from illicit ivory, especially when sellers often claim their ivory is mammoth to get around laws. Enter: stable isotope analysis.

Why do people just loudly watch tiktoks/reels on public transit now? When did headphones leave the zeitgeist? Where did shame go?.

So everyone else already knew that hitting the windows key + v lets you access your clipboard, right?

oh and this is at places I'm pet sitting I don't have cleaner money myself haha.

Where am I supposed to be when a cleaner is cleaning the home I'm in?.It feels rude to just sit at my computer and let them work around me, it also feels rude to hide outside (which is what I'm currently doing).

Today I learned that researchers in Japan are doing in-insect synthesis of oxygen-doped molecular nanocarbons by feeding caterpillars kidney beans mixed with agar and nanocarbon substrate. #WhatILearnedToday.(Thanks @robinson_julia!).

I miss when my mom used to ask me what I learned at school every day, because I'd have such good answers now. Yesterday I learned that peat fires can burn all winter long under the snow and then flame up again the following summer.

Honey made from the nectar and pollen of rhododendrons is toxic. It contains grayanotoxins (named after Eubotryoides grayana from which it was, I assume, first isolated). Called mad honey, it can cause grayanotoxin poisoning also known as honey intoxication. #thicktrunktuesday

The archaeologists believe that, as opposed to the communal hallucinogenic use that was common in other contemporary cultures, for the Chavín people, its use was exclusive to leaders and helped to establish and reinforce class structures by creating an air of mysticism and power.
