You are not an engineer because you use math in industrial settings. You are not an engineer because it sounds cool. You are an engineer because you have studied and understand the duty to protect the users of your technology and you hold this as central to your outlook on your work

Glyphosate-based herbicide exposure triggers genetic adaptation but not diversity collapse within bacterioplankton species (reposting with the article title and a gratuitous glam shot of the lake these bugs called home until we rudely plopped them into experimental ponds...)

Omigod, this is the most heartwarming story possible! Backpack (bear 89) is the son of the 2019 winner of Fat Bear Week, Holly (bear 435). In 2007, he injured his foot & a practice of riding on momma's Holly's back had a new meaning: he was mobility-restricted while it healed. So Holly moved him.
From DISCVR blog's Facebook page, a momma bear & a yearling cub on her back in the shallow water.  I think the background has been swapped out, and I can't rule out some AI use there?  God, Facebook has become the social media for AI slop : (

The title of the article, which I link below, is "How Bear 89 earned the name Backpack"

The rationalists and effective altruists all love demanding that you read their actual writing before you judge them, and so I am in fact doing that. if they were as smart as they think they are, they’d have figured out that telling critics to actually read their work is a *terrible* strategy.

Pompeii is a UNESCO world heritage site not because it was remarkable in its prime, but because it survived to our era untouched: one moment, preserved for all time. But future generations won't know what OUR world was like unless we do the same. This is why we MUST bury Toronto with a volcano
