The boring parts of science

Science is exciting, right? You explore, you experiment, you make discoveries. You see things for the first time! Science is fun. But, it also has its boring parts. Today, for example, I spent four hours pipetting, non-stop. 280 tubes. No robots, no multichannel pipette. Just manual labor. The pipetting marathon is for an experiment, which […]

Visualizing gene expression over developmental time

Visualizing the dynamics of gene expression patterns over time is a challenge. But this is a nice way.

Native video processing in Python

I’m refactoring the image processing functions of the Cifonauta database and wondering if there’s any Python library with native video processing capabilities. For the past years, I used a subprocess.call() to run a FFmpeg command to scale down and convert video files for the Cifonauta website (which is Django-powered). The ffmpeg command has some niceties […]

Reply by Email

Blog posts are an invitation to interact. This usually happens in the comments section down below. But, posting public comments isn’t for everyone and it’s not the best option for every type of conversation. Often, a more direct and private response works better. As an alternative to regular comments, I added a reply by email […]

Goldfish evo-devo

Kinya Ota’s Lab investigates the embryonic development and evolutionary biology of goldfish. Their YouTube channel has a great diversity of videos describing laboratory techniques, culture conditions, developmental time lapses, and a lot more. I’ve seen a few videos about fertilization and embryos, but I just found out that they’re doing a series on goldfish evo-devo! […]

Cephalic furrow preLights

preLights is a (another) great initiative from The Company of Biologists where teams of scientists review and comment on preprints of interest for the biology community. I was delighted to hear that they were going to highlight our cephalic furrow preprint (Vellutini et al.) combined with the cephalic furrow preprint of Lemke and Wang labs […]

Combinatorial Wnt landscape in Brachiopoda

Small note to say that our paper about the brachiopod Wnt landscape is now online on bioRxiv! Vellutini BC, Martín-Durán JM, Børve A, and Hejnol A (2023). Combinatorial Wnt signaling landscape during brachiopod anteroposterior patterning. https://doi.org/10.1101/2023.09.03.556047

Larval stickers <3

Marine invertebrate larvae are incredibly diverse. They have all sorts of unique features—tentacles, lobes, bands of cilia, shells, bristle hairs, etc.—which they use to capture food, to swim, to protect themselves from predators. Their morphology is functional. But also beautiful. That’s why I was excited to discover these larval stickers made by Dexter Davis: They […]

Chief Adjuah on Tiny Desk

Last week, we attended a concert at a local jazz bar, where the band performed the songs of Chief Adjuah (formerly Christian Scott aTunde Adjuah). I had not heard of him before. I’m currently listening to his complete discography, and enjoying it very much.
