This fetid landmark, this historical stain on humanity is primarily due to the stunningly reckless obliteration of America's foreign assistance agency earlier this year.
Led by the richest man on earth. In secret, on a weekend. With zero analysis or discussion of its catastrophic impacts.

A beautiful moment in the Ecuadorian Amazon - a small huntsman spider (possibly Meri sp.) just finished molting and now has a new set of clothes! I gotta say I envy them sometimes. Who wouldn't want to come out of their own skin as a prettier, slicker version of themselves?

Another cool find at Emerald Arch in Ecuador was this membracid treehopper (Anchistrotus sp.) with its enormous helmet. While much more sluggish compared to other treehoppers, this species is quick to break off and drop its helmet when disturbed, allowing it to take off swiftly to escape danger.

I really hate it when scientists keep saying that “we need to rebuild trust in science,” because it implies that scientists are to blame for the mistrust rather than the millions of dollars of dark money that have funded political attacks on science in order to advance a far right agenda.

Pumpkin Patch Tarantula!🕷️🎃
One of the most incredible spiders in the world, this Tarantula (Hapalopus sp.) lives in the Ecuadorian Amazon!🌳
When people think of Tarantulas, we mainly think of large, plain coloured spiders, but in the neotropics we enter a world of colour!🧡🖤

One of the funner moments from my South Africa trip occurred when these two little borbs decided to chase each other on the edge a lagoon.

Oh, I love this. A new species of sea anemone was discovered recently that parks itself on top of a hermit crab shell like a hat. It seems to feed partly off the crab's faeces, but it also excretes a hard shell that extends the crab's home. In return, it's carried around the seafloor like a king.

This is what the band of the Milky Way would look like at night if your eyes could see radio waves. A hidden beauty.
It's a new image created by the Murchison Widefield Array, which scanned the sky in 20 radio "colors" over frequencies from 72 to 231 megahertz. 🧪🔭
