Our paper about the function of the cephalic furrow in the fruit fly is ready and now available as a preprint in bioRxiv! To access: https://doi.org/10.1101/2023.03.30.534554 P. S. Apart from the poem The Great Divide, I didn’t write much about the cephalic furrow here. But this will change.

Introduction to Science Mastodon
After a first try back in 2020, I’ve recently migrated my account to my new social handle (@bruvellu) and started using Mastodon again. I’m excited about it. Migrating away from Twitter (and other corporate social silos) will be good for the web in general and for science communities in particular. Here’s my introduction to the […]
Last year I published a snapshot of a mitotic wave in a fruit fly embryo. Here’s the video of that same embryo going through cleavage (nuclei divisions) and gastrulation (cell movements): Mitotic waves What you see at the beginning of the movie are the cycles of synchronous nuclei divisions. They happen in waves from the […]
Mechanobiology investigates the role of physical forces in embryonic development. I’ll present my work on how the fold that divides the head from the trunk in Drosophila embryos—the cephalic furrow—may have an important mechanical role in gastrulation. The conference Mechanobiology in development and disease is happening in the EMBL Heidelberg.
The Great Divide
Cephalic furrow the early foldDivides the embryo in one go.Pulling in on its ownDeep it sinks into the yolk. This great divide of tissue foldSplits the embryo in back and front.But why the furrow once it growsStretches flat and gone it goes? A fold that folds and then unfoldsLeave us wondering what’s the role.

When I film embryos under the microscope, some will be younger and some will be older than others—they are never in perfect synchrony. This is fine when watching the recordings of individual embryos, but becomes an issue when you want to watch two (or more) embryos developing side-by-side. In my case, I want to identify […]
Fly Station is ready for the #LNdWDD @mpicbg
A short video that I made about the embryonic development of the likeable Drosophila, also known as fruit fly or vinegar fly, won an honorable mention in the Small World in Motion. The details on the techniques I used and the video on its full resolution are available for download and re-use on the Wikimedia […]
