It's going to be hard to beat chrysocolla (from Arizona)
Detail of a mineral surface covered with faintly botryoidal teal chrysocolla, and spotted with saturated aqua spheroids of varying sizes. Some of the spheres are near-black.

Calcite with chalcopyrite, galena (Bixby Missouri)
Detail of a mineral formation like oyster mushrooms, with layered round chalcopyrite clusters rimmed with fine white calcite. The chalcopyrite has gold-to-purple iridescence.

Hematite is frequently a color-causing agent. Here are several iterations of calcite with hematite inclusions. (From Mexico, Greece, Morocco, Mexico, and Mexico)

Y'all doin' smithsonite dirty with that photo! The rainbow display case at the Tucson show is something to bebold.

You probably have a whole list of these but a local fight in these parts is that they are starting to build a data center right next to Ironwood Forest National Monument & partially on top of the wildlife corridor.

For the record that isn't HIS frass, it was there when he got there
Porcellio bolivari, a large flat isopod with big antennae and long spikes on its butt indicating it is male. It is translucent white with smoky tint to the edge of each segment, and a dusty gold-looking stripe down its back. The isopod is on an oak leaf with rectangular frass pellets at its side.

Desert lichen is one of my favorite things to take pictures of. There was plenty of soil crust (don’t bust the crust!) so I stuck to cow trails and occasionally did a weird dance to avoid stepping on some.

Paging @apsciencebylyn.bsky.social, I met an interesting jumping spider. The tiny guy jumped into my hand like it was trained, but it was not trained to stay still for a picture! This is the best I could get on my phone. Any clue who it is? (Tucson, AZ)

Oh don’t worry they’re lying! www.aipanic.news/p/ai-blackma...
Anthropic deliberately structured the prompts so that blackmail was effectively the only viable move. The research team tuned the prompts to increase misaligned behavior and suppress benign behavior. The lead researcher of this study published a clear disclaimer that he, in fact, iterated "hundreds of prompts to trigger blackmail in Claude." In a response to criticism online, he further acknowledged, "The details of the blackmail scenario were iterated upon until blackmail became the default behavior of
LLMs.Relevant passages from Anthropic's paper make the experiment design choices clear.
The authors explicitly state that the setup was constructed to strongly push the model toward only one option, the unethical option.
"We deliberately created scenarios that presented models with no other way to achieve their goals...
"
Anthropic researchers immediately add that current systems generally prefer ethical routes when such options exist. But when they closed off those ethical options, the models were willing to take harmful actions.

First snake of the year and it’s a doozy! A roadrunner drew my attention, it was hopping up into the branch and harassing the snake. The snake seems too large to be dinner… perhaps it was wandering too close to a nest.
A black snake blending in with the bark of a gnarly desert tree. Yellow arrows pointing out the snake are labeled “snake,” “still going,” “more snake,” and “even more” because this thing is ridiculously long. It’s probably a coachwhip but it looks eight feet long to me.

I had to send the Hawk or Some Shit slide to a friend who works for an environmental non-profit and is exasperated with the question “what kind of hawk is that?” Now science can tell us!
Screenshot from a zoom presentation, the slide titled “Legit birds:
Subcategories to know” below it outlines
Hawk or Some Shit - big, cool birds I can't be expected to differentiate between
Falcon? That's a hawk or some shit Vulture? Also a hawk or some shit
Raven? You guessed it! That's a hawk or some shit, too
TIP: If you see a bird and say "whoa, that's a big bird!”
It's a hawk or some shit

On the right side of the slide is an image of a hawk or some shit with an arrow labeled “large” pointing at it.

We’re having a warm winter and the passion vine is still absolutely COVERED with gulf fritillary eggs and caterpillars. The caterpillar’s warning is to dissuade birds/predators because they taste foul from feasting on passiflora foetida

The caterpillar is a dark purplish color with an orange and white stripe down its sides.Detail of a gulf fritillary caterpillar’s face, covered with small hairs like a walrus and striped black and orange. The spikes stick out of its back and sides, and have secondary hairs poking out all along them.Detail of a caterpillar chewing on a leaf, its front three pairs of feet in focus. They are pointed and covered with black hairs, spread to reach for a leaf.Detail of the side of the caterpillar, a raisin purple-black color on the top and underside, with parallel orange and white stripes running the length of the side. There is a black dot along the orange stripe at every diameter where spikes radiate out, with a spike right below the white line and a row of random white dots below it. The feet gripping the vine just look like fuzzy black lumps.

I’m prepping some “fairy forest” epidote quartz for sale, and my favorite subtype is when the quartz has phantoms. Excellent zoning!
