Although my Inktober dreams flopped, I’m happy to recommend you some scientists who were far more consistent and created amazing art 👇

@elliejameson.bsky.social makes incredible bacteria and phage illustrations 🦠
@irinabezsonova.bsky.social brilliantly reinvented props for protein-themed drawings 💪🏻

While several studies show reindeer lose circadian rhythms in behaviour and sleep during the polar winter, a study from last year suggests their metabolic rhythms are preserved, as separating competing metabolic processes helps save energy when food is scarce 🍽️

Uncoupling of behavioral and metabolic 24-h rhythms in reindeer
Meier et al. report a seasonal uncoupling of metabolic and behavioral 24-h rhythms, with high metabolic rhythmicity in winter and spring. Together with reduced rhythmicity in summer and fall, this sea...

This drawing ties into both prompts for #day5, #deer, and #day19, #arctic. It’s a cute take on how animals in polar regions, like Arctic reindeers, lose some of their circadian rhythms when the day/night cycle disappears in summer or winter 🦌

What about luciferase for the firefly prompt?

Thanks Lena! I am delight-ochondria to hear that 😍 (though this last pun is a bit of a stretch 😂)

Absolutely amazing 😨🤩

After first seeing the image, I could not help but see a flower, so I shaped the cover art around one. In this version of #vangogh ’s sunflowers, the yellow petals represent healthy mitochondria around a stiff nucleus, while red petals show stressed mitos pressing against a softened nucleus 🌻

Even cooler: mitochondrial stress also softens the nucleus. You can see it in the image below: on the right, the blue nucleus in cells lacking 𝘊𝘭𝘱𝘱 is dimpled by multiple red mitochondria 🔬
September 23, 2025 at 3:34 PM
When 𝘊𝘭𝘱𝘱, a key mitochondrial quality-control gene, is knocked out, mitochondria become stressed and send signals to the nucleus via the metabolite 2-hydroxyglutarate (2-HG). Signalling by 2-HG nudges the cell to build bigger #lipid droplets, whitening the BAT ⚪

Harshita's paper broadens our understanding of how damaged #mitochondria make brown adipose tissue (BAT) “whiten,” a process observed in conditions such as obesity and aging 🧓🏽

I’m really cringing rewatching the video, but I’ll share it anyway. Not just for your Schadenfreude, but also for feedback: what messages stand out? Anything we could’ve communicated better in 10 minutes? 🔗 youtu.be/-FFBiwrFrwg

I stress 𝘴𝘰𝘮𝘦𝘩𝘰𝘸 because preparing for this slam pushed me to finally read 'Power, Sex, Suicide' by Nick Lane. That book made me realize how the origin of mitochondria is way more complex than simply “one bacterium swallowing another.” Highly recommend ⭐⭐⭐⭐⭐

Ich hab den Link meinen Freunden in Köln weitergeleitet 🤩 ein paar haben gefragt, ob du das in Zukunft auch auf Englisch machst 🥹
