The InverteFest is here. A moment to celebrate the overlooked diversity of invertebrates around us. I’m re-posting a video I made for the Cifonauta account on Instagram showing different marine invertebrates moving around under the microscope. Enjoy! Invertebrate Gallery Check the gallery below to find out the identity of each marine invertebrate in the movie […]
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 […]
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!
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 […]
Something that I began doing more often is converting videos of developing embryos or marine invertebrates to animated GIFs. But how to do this conversion without affecting the quality of the video? Some time ago I found this guide to convert videos to high-quality animated GIFs using the tool FFmpeg. The trick is to generate […]
Live footage of entoprocts! Tiny colonial invertebrates that capture food with a crown of ciliated tentacles
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 […]
