Biology is exciting and informative, giving us insight into the beauty of life. What we see with the microscope is the amazing developmental process by which form emerges out of unformed material. To watch an embryo develop is to see the life of a new individual emerge, gradually, stage by stage, from very simple material […]

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 […]
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 latest True Facts about Sea Stars is unmissable. The video is filled with delightful echinoderm biology and even covers some recent discoveries on these enigmatic creatures. Watch it!
Hi! I’m migrating from my old domain, organelas.com to brunovellutini.com. To continue following the blog, update the feed address to brunovellutini.com/en/feed. See you!
Here’s a personal view about body symmetry and body openings from someone who lived through the evolution of bilateral symmetry. Form? I didn’t have any; that is, I didn’t know I had one, or rather I didn’t know you could have one. I grew more or less on all sides, at random; if this is […]
Every time I open Spotify, I see the pattern of engrailed expression in an early Platynereis larva. Once you see it, there is no turning back! Reference Prud’homme, B., de Rosa, R., Arendt, D., Julien, J.-F., Pajaziti, R., Dorresteijn, A. W. C., Adoutte, A., Wittbrodt, J., & Balavoine, G. (2003). Arthropod-like expression patterns of engrailed […]
UNESCO released a recommendation last year with the first international framework for open science policy and practice. This is something every researcher and institution should be aware of and strive for. Science is an amazing endeavor, but it can be more diverse, inclusive, and fairer. The four pillars of open science Open scientific knowledge (publications, […]
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.
