Every time I hear Chicago my heart is at Demon Dogs. #chisky #🌭
A photograph of the former location of Demon Dogs, a hot dog stand under the Fullerton L stop in Chicago. They played music by the band Chicago exclusively.

Wait even this guy and his magnificent murder mittens?
A photo of a Canadian lynx in profile, walking on the snow. Its paws are so disproportionately large it resembles the Mr Hyde version of Bugs Bunny. A photo of a Canadian lynx bounding towards something a little to the right of the camera. Its front paw is aloft and roughly the size of its entire head.

Pollen pants are so hot right now 🐝
#bloomscrolling #photography
A close up photograph of a bee standing on a red and yellow dahlia flower. The bee has a prominent orange pollen ball on its hind leg, aka “pollen pants”.

Aw, reminds me of this photo I took of my cat (Midnight) when I was about 5 or 6 years old. Her face is out of focus but I cherish the photo, anyway.
A film photo of a black cat walking towards the photographer across a blue blanket. The cat has one foreleg outstretched, her head is pointed slightly down and her eyes are fixed squarely at the lens.

A hearty hello to the Haleakala observatory and @hawaiianimages.bsky.social from the skyline trail! (We almost made it to the top but opted to turn back due to foul weather.)
A photo of a dirt road pointed uphill towards a small peak. A man made structure is visible at the top of the peak. The sky is blue above and clouds are gathering below.

Made a friend at the Volunteer Park dahlia garden. #invertsky #photography #🪰
A close-up photograph of a small fly sitting on the petal of a yellow and pink dahlia. A close up crop of a fly (I call him Jeff) sitting on a dahlia petal. He’s a tiny fella, with a grey-brown body, reddish-brown compound eyes, and sparse hairs.

This story makes me irrationally angry on behalf of Keanu Reeves. This dirtbag director knew he was a nice guy and exploited the hell out of him.

From the Wikipedia article in the quoted post:
Charbanic had been friends with Keanu Reeves after having directed a number of music videos for his band, Dogstar, and was insistent on casting Reeves as killer David Allen Griffin as he was interested in seeing Reeves play against type as the villain. Reeves has stated that he was not interested in the script but was forced into doing the film when Charbanic forged his signature on a contract. He performed the role rather than get involved in a lengthy legal battle. Reeves was forced to accept 'union scale' salary, while James Spader and Marisa Tomei earned $1 million apiece for their work.

A gif from the 1998 Coen brothers film The Big Lebowski. The Dude is in the center of the frame, in an ornate chair, in Lebowski’s house. He has a stern look on his face. The text reads “this aggression will not stand, man.”

Post a random picture, or else everything will go bad in September (it won't but it's a fun idea)
A photo of a Shiba Inu dog lying Sphinx-style on a wooden floor, next to his human’s foot, taken at a low angle. There are table and chair legs in the frame. The human’s foot is clad in a snow boot with an ice traction spike covering. The dog is giving the camera a notedly dubious look, as if to say “what are you looking at?”

Wait it’s time to share doggle photos?! Hold my beer
A photo of a cattle dog wearing red goggles. The photo is taken from above, the dog is looking up at the photographer through her goggles. It is snowy on the ground, the photographer’s leg and Nordic ski are visible in the bottom of the frame.

The creeping horror
#photography #smokehour #seattle #fireseason
A photograph of a city street. In the gap between buildings and trees, the sun is visible in a blue sky, however a brown cloud of smoke hangs in the air below, looming menacingly. A very wide angle photo of the Puget Sound skyline, pointed West from Seattle. The space needle is a small feature in the center of the frame. The sun is setting into an expanse of brown smoke. The rooftops in the foreground reflect the brownish red tint from the smoke. A happy blue sky fills the top of the frame. A telephoto photograph of the Puget Sound skyline taken from Seattle. The Space Needle is visible in the left side of the frame, the horizon is around a third of the way from the bottom. The mountains of the Olympic peninsula are shrouded in reddish-gray smoke, a smoldering sun hanging in the upper right of the frame. It’s beautiful and nasty.

Don’t forget about Cary Grant!

(Based on the other comments, seems like “action movie guy” is its own category, which would include John Wick.)
A still from the Hitchcock film North by Northwest. Cary Grant is in the foreground, wearing a grey suit, grey tie, and white shirt. He’s running towards the camera on a dirt path. A biplane is approaching Grant from the rear, flying low.

A photo of a sea urchin. It is kind of purple and very spiny. The bristles are short, though, and would scratch and itch with deep satisfaction

Ok #invertsky I’ve got another critter to ID. Found this little dude on a flower in Seattle, almost certain it’s not a fly, doesn’t really look like a wasp or a yellow jacket, can’t figure out if it’s a bee. Any ideas? 🐝
A close-up photo of a yellow and black striped winged insect on a flower. This insect has yellow and black mottled eyes, which don’t connect at the top of its head. It has a narrow waist between the thorax and abdomen. It is lightly hairy, and pollen is sticking to the hair. That said, it does not appear to have “pollen pants,” as some bees do. It has six yellow legs, two pairs of wings folded on its back, and elbowed antennae. A close-up photo of a yellow and black striped winged insect on a flower.

🚨Cute sit alert🚨
This is how my dog, Skinny Pete, is sitting.
#dogsofbluesky
A photograph of a small dog, in profile, sitting on stairs. The dog’s rear legs are on one step, in a seated position, while his front legs are one step down, and erect. His back is mostly flat, as though he were standing on all fours. He appears both noble and silly.

When the Mandalorian was hot shit I was like “this is the only Mando I care about.”

Didn’t get this off the camera in time for Pride month, but I love this mural on the @hrc.org building in DC.
#photography #pride
A photograph of the Human Rights Campaign building in Washington DC. There is a mural featuring pride flag color stripes with an eagle in the center and the words “these colors don’t run” underneath. The eagle’s wings are rainbow-colored. It has pink nails, full eye makeup, and a leather harness.

For no particular reason: I think this was my favorite installation at the NMAAHC when I had the opportunity to visit last week. Bricks aren’t people, and these bricks only represent a fraction of the people Jefferson enslaved. It does, however, add literal weight to one’s perception of the matter.
A photograph from the National Museum of African-American History and Culture. In the photo is a statue of Thomas Jefferson. He is standing with a book in hand. At his feet is inscribed “Thomas Jefferson and the limits of freedom.” Behind him stands a wall constructed of bricks, approximately 17 bricks wide. The height increases from the outside going in, with the tallest columns 24 bricks tall. On each brick is the name of one of the more than 600 people Thomas Jefferson enslaved.

What actor’s expression in a movie will stay with you for the rest of your life?
A still from the movie The Shining, from the final scenes. It shows Jack Nicholson from the shoulders up, dusted in snow, presumably frozen solid. There are trails of ice running down his face. His eyes are rolled up into his skull, his lower lip has fallen enough to show his bottom teeth. His jaw is set.

I know #ISTH2025 is nearly over, but, if you need a snack, the chilled cucumber soup with crab at Petite Cerise f’in slaps.

I’m intrigued by Arijit Biswas’s proposed model of the FVIII B domain as a flexible glycosylated coating on FVIII. Think cotton candy, not a hard shell. His data suggests the unstructured nature of the B domain could function as a soft barrier, fine tuning hemostasis.

#ISTH2025 @isth.org #hemesky
Conclusions > B-domain wraps around the FVIII core, stabilizing its structure and shielding key functional domains without forming a separate appendage. >AFM and cryo-EM studies reveal globular architecture of FL-FVIlI with size differences attributable to B-domain presence; pdFL-FVIII shows vWF-bound structures. > Glycosylation in the B-domain enhances FVIII folding, secretion, and structural stability by mediating its domain interactions with the core domain. > Furin cleavage facilitates controlled unwrapping of the B-domain, promoting efficient vWF binding and reducing structural tension. > The shielding effect of the B-domain limits access to immunogenic and cleavage sites, protecting against premature activation and inhibitor binding. > Overall, the B-domain plays critical structural, functional, and immunological roles-not dispensable, but regulatory.

I think that’s all for today from #isth2025

If you need me I’ll be ironing my poster: PB1345, on display tomorrow! Come say hi!
A photo of an ironing board, a scientific poster is draped over it. An ironing heats up on a nearby table.

A photograph of a long hallway bathed in gentle sunlight. There is a busy carpet with a blue and yellow repeating geometric pattern receding into the distance, a cream-colored ceiling overhead. On the right side of this hallway, extending as far as the carpet, are panels of windows with low cushioned orange benches spaced at regular intervals, interspersed with potted plants. The view out the windows is unfocused blue and green of summer in DC. There are a few people sitting on the benches, all singletons, presumably having a lovely time.
