Our PhD student Justine Bélik has published as a preprint the first epigenetic clock in the mangrove rivulus, and the first ever on a self-fertilizing species. With this clock, we're able to predict the chronological age of the fish with a mean absolute error of 28.7 days.
Epigenetic aging in a self-fertilizing vertebrate, the mangrove rivulus Kryptolebias marmoratus
Background: Since Horvath (2013) and Hannum (2013), DNA methylation has emerged as a reliable biomarker for estimating age. Predictive models, called epigenetic clocks, are being built across the tree...

We're searching for 2 PhD candidates to work on our new project about the conservation of Beluga whales in the Saint-Laurent river. Two positions are open, in Montreal and in Namur. The candidates should show an interest in conservation biology, ecotoxicology, molecular biology and bioinformatics.

Happy to announce that we will start soon a new research project in collaboration with our colleagues from Montréal on the endangered population of the Beluga whale from the Saint Laurent river. Thanks to FNRS and FRQ 😀

Il vous suffit d'écouter la 1ʳᵉ minute de cette vidéo pour comprendre que les US viennent de basculer dans une nouvelle ère, la pire de son histoire.

Et, ce faquin fera des émules, même chez nous ! J'entends déjà certains échos dans les médias.

US national parks are among the most wonderful and spectacular of the planet. This action at Yosemite, a park that I know well and that I love, is a brilliant symbol of resistance against the fascism that has taken place at the WH. www.nytimes.com/2025/02/24/u...

Organizers said the inverted flag, historically used as a sign of distress, was meant to draw attention to the Trump administration’s cuts to the National Park Service.

Our former post-doc Anthony Mathiron published a new article in the Belgian Journal of Zoology. This article shows that cortisol (the stress hormone) level can predict behaviors associated with fish personality traits. belgianjournalofzoology.eu/BJZ/article/...

A conservative congressman, Andy Ogles, suggests to modify the 22nd amendment to allow President to run for a 3rd term. It's obviously dedicated to his mentor DT. However, I think it's a brillant idea and I'm ready to start the campaign: Obama 2028 !
