different day lengths give cyanobacteria seasonal information, but could they also have informed the evolution of their circadian clock? check our paper and Chitrang's thread on it below! And also Michael Rust's paper which was published back to back with ours: www.cell.com/current-biol...

Self-sustained Circadian Oscillators Confer Enhanced Fitness Under Changing Photoperiods ☀️ @currentbiology.bsky.social @drummonk.bsky.social and I wrote a dispatch on fascinating back to back pubs from the labs of Carl Johnson and Michael Rust. www.sciencedirect.com/science/arti...

Bumping this to the science feed 🧪 Interesting science to ponder the interplay between seasonality and circadian rhythms.

Our new paper is out in @currentbiology.bsky.social where we address the question of why self-sustenance, a defining feature of circadian clocks might have been selected, when environments on Earth are rarely constant! www.sciencedirect.com/science/arti... #circadian #cyanobacteria #evolution

In the 1960s/70s, as early software papers were talking about programmer "ability" (aided, I regret to say, by psychologists with terrible 1960s views of ability) there were already papers saying that measuring the time it takes to complete a task is neither a measure of ability nor productivity

Why do insects fly around artificial lights? They don't actually want to fly towards them, they just can't really get away from them. Insects naturally tilt their dorsum towards a light source, and as a result end up flying around it in circles, trapped. 🧪 🦋 www.nature.com/articles/s41...
