Incredibly proud to share this work, almost 6 years in the making, out this month in Science!!! 🎇

We've known for over a century that eukaryotes of all kinds anticipate the seasons (think: hibernation, flowering, reproduction!), but what about bacteria?🦠

cleaning up my new lab space yesterday we stumbled upon a treasure trove of floppy disks 💾 which prompted my 00s-born RA to ask me how did people operate these "back in the day" 💀

Maybe instead of committing atrocities, we could just make the rich pay their fair share and have universal healthcare and affordable housing instead.

Idk, just spitballing here.

Tonight, we did something everyone counted out. We proved to a nation that states like Tennessee are still worth fighting for. The margin was close, and that can only be attributed to the thousands of volunteers who showed out. This is just the beginning.

A very interesting piece on the evolution of #photoperiodism and its relation to #circadian #clocks by Luisa Jabbur @jabbur.bsky.social and Carl Johnson.

last year we published on how cyanobacteria predict & anticipate the seasons by using their circadian clocks to measure day length, through processes remarkably similar to those used by eukaryotes (despite little phylogenetic conservation) +

Thanks to @jabbur.bsky.social I have just learned of "nutritional yeast" which is simply dead yeast + vitamin B for people to eat. Fine. However, it is being marketed as entirely PLANT based?! NO.
S. cerevisiae IS NOT A PLANT!

accidentally ruined my mycologist friend's day by letting her know that nutritional yeast is labeled as "plant-based"

SO HAPPY to share our new paper in @currentbiology.bsky.social! Using volumetric EM, we found daily shifts in synapses, vesicles, and mitochondria that accompany neuronal remodeling, linking structural plasticity to changes in how s-LNv neurons influence their targets

The findings of a study in Nature Climate Change show that artificial light at night disrupts the fundamental energetic constraints on ecosystem metabolism, warranting the inclusion of light pollution in global change and carbon–climate feedback assessments. go.nature.com/44cCKWm 🧪

I'm terrible at posting but I had an absolute blast giving a seminar at the LIPhy at Université Grenoble Alpes earlier this week, hosted by the great Irina Mihalcescu!

I wonder how my cat rationalizes it when I am out of town for trips

perhaps "ah mother is once more on one of her long hunting trips"

but most likely "that damn idiot got lost again, didn't she"
