When genus deserves to be a family 🦠🔬

Recent phylogenomic analyses showed that the genus Methanobrevibacter is severely underclassified. We propose reclassifying it into a family, Methanobrevibacteraceae consisting of 11 genera.

🇫🇷 Kerguelen, l'archipel français le plus isolé sur Terre

🧭 Au large du sud de l’océan Indien, les îles Kerguelen forment un archipel volcanique isolé à plus de 3 200 km de toute terre habitée.

🌬️ Découvert en 1772 par Yves de Kerguelen, l’archipel fut longtemps chassé pour ses phoques et ses baleines. Le climat y reste froid, océanique et presque toujours balayé par des vents violents.

🐧 Les côtes abritent manchots, albatros, éléphants de mer et otaries, tandis que le chou de Kerguelen et quelques plantes dominent une flore rare. Lapins, chats et rennes introduits ont toutefois bouleversé ces écosystèmes fragiles.

🔬 Port-aux-Français accueille seulement quelques dizaines de scientifiques et techniciens, ravitaillés par la mer quatre fois par an.

🛡️ District des TAAF inscrit au patrimoine mondial de l’UNESCO en 2019, l’archipel n’est accessible que par mer, via le Marion Dufresne.

🧬Possibly one of the most important genetics preprints of 2026 has just been published: the flagship paper of the Vertebrate Genomes Project.

An ambitious effort to generate near-complete and near-error-free reference genomes for all living vertebrate species.

The authors present 816 high-quality reference genomes covering around 95% of major vertebrate evolutionary lineages. Most assemblies are at chromosome-level quality and some are fully diploid telomere-to-telomere genomes.

Using this resource the authors reconstructed the genome of the last common ancestor of vertebrates, studied the evolution of sex chromosomes, explored 3D genome organization and compared epigenetic landscapes across hundreds of species.

This dataset will likely become a foundational platform for evolutionary biology and comparative genomics.
