Researchers @mrclmb.bsky.social found changes in cells that explain why #mammals, including human ancestors, changed from #nocturnal to #diurnal, providing clues on one of the most relevant events in mammalian #evolution.

137: Seasonal Affective Disorder Photo Description: Panel 1: Present is a barn owl named Cupcake inside her nest wearing a pink hat and pink scarf. She has a yellow mug with steam coming off of it. The mug says "HOOT IF YOU'RE HAPPY". Her nest is a variety of browns with snow and a single withered forget-me-not flower on the outside. They're in a snow covered brown tree with an orange and purple sunset background. Visiting her is a sad pygmy owl named Coffee. Cupcake asks in nighttime white text, "What's wrong, Coffee? Aren't you loving how early it gets dark?" Panel 2: The orange background fades and the purple gets darker. Coffee replies in daytime black text, "I'm a diurnal owl." Panel 3: The orange background is gone leaving only dark purple. She continues, "Seasonal affective disorder really gets to me." Panel 4: Stars are now visible in the background. Cupcake responds, "That is valid. Since I love the night, I can use more of my energy to support you if you would like." There is an orange heart above Coffee.
Coffee will almost always be seen in daytime backgrounds. It's also why her text is black rather than white, more contrast. Just makes her unique to other owls.

overcaffeinated-aro Follow ok not to be that guy but like. labor rights and working class rights can coexist with 24h services and late amenities. its certainly hard to do so without worker exploitation in this political and social environment, it's not a conflict likely to resolve overnight. but 24h services are important and especially valuable to those of us that are disabled or are on a different circadian rhythm. in fact more professional, health, and government services should be available or at least possible to work on asynchronously (if applicable) during late or odd hours, while workers also get sufficient pay for their labor and proper consistent scheduling. this would be much easier on the workers with night schedules if the entire professional world didn't grind to a halt at 5pmEST
So much this. #Diurnal v #Nocturnal v #Crepuscular human animals.

5/ Some species were #nocturnal predators that had been attracted to the artificially illuminated reef.
Other were #diurnal (day-active) species that had been roused from sleep ⏰

The beauty of #avianretina is ever expanding.
These magnificently colored dots called #oildroplets are located in the #photoreceptor #cones and intercept and filter the incoming #light.
They're found in #diurnal #reptiles and #birds and some other taxes, forming curious patterns.

my #diurnal verses
shy and timid
maybe an excited #ramble
if you're lucky
but it's when the darkness comes
bathing all
in shadows and secrets
that my boldness blooms

Sketch of a "realistic" sun, a circle with solar flares and whatnot.
The #diurnal angel deaths drove us mere human colonists to live nocturnally. Daredevils followed a crepuscular schedule and were happier for the glimpses of sunrise and sunset. Yet we still called them angels, because they were beautiful and terrible even as the very sight of them burned us. #vss365
She didn't want to get up. It was awful sometimes, being the partner of one who was #diurnal. As they crawl into bed, #warm from the sun, you exit, the nocturnal #quiet chills you.
If only the #honor of leaving her kind was enough.

Nocturnal, #diurnal, and the third thing, crepuscular, for creatures of dusk and dawn.
They neither accept nor reject the day. They do both and neither. They know eagle and owl, orca and eel, but are themselves unknown.
To live in twilight is to remain in twilight.

#vss365 A shell blast had blown out the window & rearranged my kitchen. I picked up the kettle on the floor & filled it with discolored water. At least there is running water—& electricity. I make a cuppa with a used tea bag. No Jaffa's, though. My #diurnal routines allowed me a modicum of normalcy.
I miss 3AM
Book in hand
Or just staring
Cigarette burning
Cat pleased I was nocturnal
I'd breathe in the sounds of the night
Now I am #diurnal
With work, duty, life
I slog through the light
Eyes half focused
No joy no imagination
Just day after day after day
Of damnation
#vs365
Happens during day
the boring interactions
this #diurnal life

I wonder if vampire teenagers are partially #diurnal, staying up well into the day playing video games and then sleeping half the night away.
#vss365
#Diurnal life is for suckers. All the cool stuff happens at night. No one sells their soul at noon or opens a portal to other dimensions in mid-morning.
#vss365
From bed I hear the sounds
The #diurnal routine of a new day
Dishes clatter and footfalls stutter
A shower sputters to life
Awaiting warmer water
It's muffled behind these walls
Blanketed in dawn's dull light
Sleep no longer beckons
But neither does the day
I am beautifully still
#vss365
She lived shrouded by the night, safely hidden from the world. That was before she was enthralled by one who danced in the light.
Head resting in her lap, her eyes slowly closed while watching the sun set. She smiled up at her dancer, ever amazed that she could turn her #diurnal.

From the #vss365 jukebox for #diurnal, this is Waxahatchee's version of Dolly Parton's Light of a Clear Blue Morning. I've posted this one before but it's a favorite. If you're diurnal, you can wait thru the dark night until you see the hopeful rays of dawn.

she was woken by the squirrels' #diurnal scurrying; dropping the occasional pine nut & #needle, and chattering in their playful way. the kiss of sunlight had risen past her ankles while she sat against the evergreen; the sun gathering its blanket shade. she returns the smile skyward
