Projection du film Ballet Boreal

Projection du film documentaire « Ballet boréal » de Simon Maraud et Thomas Grandremy (42 min, Tonnerre de l’Ouest & AgroParisTech). D’après une idée originale de Samuel Roturier, maître de conférence, laboratoire ESE Originaires de Thaïlande, les cueilleurs saisonniers du Chaiyaphum viennent par milliers tous les étés pour arpenter les forêts suédoises à la recherche de baies sauvages. Main d’œuvre bon marché d’une filière globalisée, ils sont au cœur autant qu’à la marge du capitalisme contemporain. Leur itinéraire croise un surprenant guide, cueilleur amateur à la fois libre et mélancolique.

Very happy and proud of communicating our recent collaborative work on Ploidy-dependent modulation of DNA replication kinetics in Xenopus available on bioRXiv and @hal_fr at https://hal.science/hal-05453497 @ijmonod.bsky.social @NeuroPSI @kathrinmarheineke.bsky.social

Ploidy-dependent modulation of DNA replication kinetics in Xenopus

DNA replication in multicellular organisms follows a tightly regulated spatio-temporal program. Although the mechanisms underlying this replication program remain only partially understood, studies in model systems such as Xenopus laevis have highlighted the importance of titrating low-abundance replication factors. Whole-genome duplications as a consequence of polyploidization introduce additional layers of complexity, yet comparative analyses of replication programs across closely related polyploid species are scarce. Here, we developed an interspecies in vitro replication system using X. laevis egg extracts and sperm nuclei from three Xenopus species with varying ploidy: diploid (X. tropicalis), tetraploid (X. laevis), and dodecaploid (X. eysoole). Replication in diploid X. tropicalis was faster than in tetraploid X. laevis nuclei, due to higher fork density and speed. Surprisingly, dodecaploid X. eysoole replication was also accelerated compared to tetraploid nuclei, suggesting that higher ploidy does not necessarily extend S phase. Since replication genes are highly conserved between these species, these results imply dynamic tuning of replication programs across polyploid species and shed light on the evolutionary adaptability of DNA replication in response to genome duplication.

Who would have guessed that lottery style distribution of grants leads to a fairer outcome for everyone? Well, except for those friends of the reviewers, anyways.

Lottery before peer review is associated with increased female representation and reduced estimated economic cost in a German funding line - Nature Communications

The authors show evidence from a German funding line that a lottery-first approach followed by peer review is accompanied by increased female representation both at the submission stage and among funded projects as well as by lower estimated costs.

Esther Lederberg, Pioneer of Bacterial Genetics

by Mercé Piqueras — “She did pioneering work in genetics, but it was her husband who won a Nobel price.” So said an obituary in the British newspaper 'The Guardian' regarding Esther Lederberg, a North American microbiologist married to Joshua Lederberg from 1946 to 1966. Being married to and working along such a phenomenal…
