I wanted to denoise a twenty-year-old photomicrograph. It’s one of the first scientific images I created back in 2003. It’s so ancient that I used a camera with photographic film, developed and amplified it to 15×10cm print, and finally, scanned it to make a digital version. I used it in my undergraduate research project and […]

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 […]
This is a bryozoan embryo exhibiting its blastopore. These animals are discreet but ubiquitous in oceans and lakes all over the world. What we see is the DNA inside the nucleus of the cells of the embryo. The color gradient indicates if the nuclei are closer (yellow) or further away (purple) from the microscope camera. […]
Something I’m doing more often is converting videos of developing embryos or marine invertebrates to animated GIFs. But how can you 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 a […]
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 […]
