Instead of: A hill I'm willing to die on I'm gonna start saying: A hill I'm having a picnic on Just... spreading out a blanket with a food basket and staying a long time ✅️ too many ppl dying already ✅️ picnics are cozy n nice ✅️ nobody wants to eject someone having a nice picnic on a hillside

frankly, congress (yes, both parties, and especially republicans) hasn’t been serious about funding public health adequately even post-pandemic. they will be under tremendous industry pressure to rebuild the military, and i don’t think they’ll spend what it’ll take to rebuild public health

French marine biologist Jeanne Villepreux-Power invented the first glass aquarium for scientific study in 1832. Her sealed tanks (with aeration & water stability) enabled live observation of sea creatures, which was revolutionary in marine research. She was born #OTD in 1794. #WomenInSTEM
Sepia-toned 1861 photograph by André-Adolphe-Eugène Disdéri of Jeanne Villepreux-Power (1794–1871), pioneering French marine biologist and inventor of the glass aquarium. She stands in three-quarter profile facing left, leaning elegantly on a tall decorative pedestal vase adorned with flowers. She wears a formal Victorian gown with a fitted bodice of intricate black lace over dark fabric, long lace sleeves, and a voluminous hoop-skirted skirt. Her dark hair is styled in a low chignon, and she gazes thoughtfully to the side in a studio setting with a neutral backdrop.

The moon creates two tidal bulges on the Earth, one towards the moon and one away from the moon. but the Earth spins faster than the Moon can go around it, so Earth's rotation drags the tidal bulges with it, the one towards the moon is slightly in front of the moon while the one away from the moon

The Moon speeding up causes it to miss the Earth by a larger margin and fall away from the Earth, and that's why the Moon is moving away from Earth by 4cm a year. But Venus spins extremely slowly, and, to make it worse: in the opposite direction to every other planet

The Google Maps AI reviews summary for my pottery studio mentions the "friendly studio cat". No review includes these words. What the reviews actually say is that the studio is a friendly place and that there is a cat. This cat is is only motivated by violence and loves biting.

A Paper Wasp on the boneset for #WaspWednesday. Polistes fuscatus. #WorldWaspWeek #bugsky #nativeplants 🌱
Four different views of a male Northern Paper Wasp (I think) feeding on white boneset flowers. Here we see the back of the wasp. The curved tips of the antennae identify him as a male. He has a black thorax with one white horizontal stripe and two vertical stripes below it. His abdomen has curved tan stripes alternating with black stripes. The black stripes have concentric circles of rust and tan on each side that get smaller and disappear near the end of the abdomen. The wings are a dark rusty brown.The wasp seen from one side. His head is black on the side and his legs are a reddish-gold color.The wasp has his face in a wispy white boneset flower, his antennae folded down in front of the flower, the tips curved like shepherd's crooks.The wasp grips a flower and drinks from it facing the camera, showing his pale yellow face and khaki tan eyes. Tall Boneset, Eupatorium altissimum. Oklahoma Northern Crosstimbers ecoregion 29a.

The reasons they sparkle in sunlight is specifically because they spend so little time above ground: - smooth, mirror-like scales also offer less resistance in tunneling. - thin layers of scale cells provide abrasion-proof coat, but they also produce iridescence in strong light. (📷:Maura Hennelly)
An iridescent snake (the same one as in the OP) is held in a human hand, forming a sort of figure 8 while held gently.  It is iridescent rainbow colored, and just a very pretty little snake.

I want to say early on that Xenopeltis are extremely challenging to keep as pets, not recommended & possibly illegal where you live. They're best & happiest when wild & free in their native habitat! But oh my goodness, they dial the colors up to 11 in bright sunlight.
Another photo, possibly of the same pet snake.  It's sort of soft-brown with iridescent rainbow colors where the sunlight hits it.  A human hand holds it in front of a broad-leafed plant.

This is a canary resuscitator, which miners would use to revive canaries that had passed out from toxic gas, because ideally not only do you care, you don't even leave the bird behind. just a little mining history and not at all a furious scream

I’m not too worried about this, actually. It’s one tox test that shows behavior change, which is a very basic start. Tox is one part of risk, exposure levels/duration matter a lot. We also don’t know if the effect actually translates to increased predation. Worth looking into, not worth alarm

From "Ineedmorebtc" on a gardening subreddit, a saddleback caterpillar, showing the saddle, a brown patch in the midst of a green patch on the bug's back, lined with white.  Both ends of the 'pillar have yellow eyespots to confuse predators, so that unless you know which is the head, either end could be.

There are two ways you will react to the image below. Never encountered: "Neat! A caterpillar with a little sports jersey on!" Encountered: "Oh god, get it away before it kills us all!" Let's meet the saddleback caterpillar (Acharia stimulea), a tiny bug that that 'hides' a painful sting.
From Brittanica Encyclopedia:
"Saddleback caterpillar
The armed and brightly colored saddleback caterpillar (Acharia stimulea) is a type of slug caterpillar moth found in North America."

There’s another round of “non-LoTR character that could resist the Ring,” as usual folks are choosing strong-willed characters. I think that misses the point. Even Aragorn didn’t trust himself with it, nor Gandalf. Strong wills are easily corrupted. The way to resist is to be fundamentally *gentle*

Let's calculate how many Hercules moths (Coscinocera hercules) would be needed to lift an adult human. They weigh 30-50 grams, extrapolate lift about 30% in excess to body weight, so ~10 grams per moth. For a 70 kg human, that means we need about 7,000 of the little buggers. Now, who has a net?
