Happy to finally share micromorph with everyone! If you are interested in performing morphological measurements of bacteria, and like using Python and Napari then this is for you! You can read about it in our preprint, and find the code on our Github repo, PyPi or directly from the napari hub!

I also loved that the plants in the surrounding garden were chosen for their connections to her story, with Everlasting Flower (powo.science.kew.org/taxon/urn:ls...) being a particularly poignant choice.

I serendipitously came across this beautiful Henrietta Lacks statue in Bristol yesterday, whose cells I put through so many manipulations during my MPhil and PhD. It’s mind-blowing to think of how many labs across the world are using her cells to make discoveries and she died having no idea of this.
A metal statue of Henrietta Lacks, surrounded by shrubs with green and burgundy foliage and various flowers.

If it’s any consolation, at one point during my PhD, I made an agarose gel with H2O instead of TAE/TBE + wondered why it was running weirdly for ~30 mins before realising. I had vowed never to do this again after undergrad when I wasted a lot of time before learning H2O was not the solvent to use.

On April 19, 1898, Camillo Golgi described what we now know as the #Golgi apparatus - a structure so pretty and unusual it took over fifty years for the scientific community to agree it wasn’t just an artefact. April 19 is #GolgiDay! Mark your calendars to honour the best organelle.

It’s my favourite time of the year! 🌸 I’m loving seeing all the blossoming trees + flowers while out and about, esp. magnolias which remind me of my hometown of Kyiv. Today, I also came across an unfamiliar flower species, which I learned was in the genus Anemonoides thanks to the iNaturalist app!

pretty and useful copper phosphate and tannic acid possess anti-inflammatory and antibiotic properties mixed in a saline solution, they self-assemble and grow into flower-like structures the nanoflowers can be attached to small strips of electrospun nanofabric to make an antimicrobial bandage

Future bandages could be armed with nanoflowers
The tiny structures may help fight deadly bacteria like E. coli.

It was exciting to show that INVs function on a degradative trafficking pathway - macroautophagy - as well as on exocytic + recycling routes. The ATG9A lipid-scrambling capacity of these vesicles may be important in other membrane-remodelling contexts 🤔 Lots still to explore! 🌈 #CellBiology

When I did my PhD at Cal Bot Gard, #Ceanothus (#Rhamnaceae) stole my heart. They're amazing chaparral shrubs, especially the blue-flowered species. I don't see them here on the East Coast, but I still ❤️ them. My fondness & fascination for the family has never diminished. 📷: C. purpureus. #Botany 🌾🧪
Photo of leafy branches and clusters of flowers. The leaves are small and have spiny margins. The flowers are small & purple.
