Country Life, or Why Apple and Samsung Still Lose to a Rooster
The countryside is one of the very few places left where smartwatches are still trying to figure out what is going on. It is a place where circadian rhythms are not measured by sensors, but by an improvised chorus of roosters, cats, hens, and a colourful cast of characters who have never opened a neuroscience textbook, yet somehow know, with remarkable precision, exactly when the day should begin. In the city, you set your alarm. In the countryside, the alarm sets you. It never begins […] -

Circadian | Adelaide @ Divide Nightclub - 08 May feat. Circadian, xela rae

Every spring I reread this article on how tomatoes respond physiologically to even a single night below 50 °F (season-long reduction in yield). I'm always left wondering whether planting them out now (lows in upper 40s) might allow an earlier harvest, albeit at the expense of total productivity. Because I'd be OK with that.

🌙🧠 #Research suggests that the human #brain is biologically predisposed to negative emotions and increased impulsivity during late night hours.
The phenomenon occurs because the internal #circadian clock naturally shifts toward lower mood and reduced cognitive control after midnight. Scientists explain that these biological changes evolved for #sleep and can lead to distorted thinking when #people remain awake.

The #circadian clock & cellular #metabolism are tightly coupled. This Primer explores a @plosbiology.org study showing how #glucose metabolism changes during the day in #Drosophila and how it is disrupted in clock & sleep mutants. Paper: https://plos.io/3Olm1M1 Primer: https://plos.io/4sUov2g

Perhaps a #circadian component to daily growth rhythms in giant clam shells. Neat study!
I love seeing the biological clock (perhaps) recorded in a such a durable way in nature.
