La régénération, processus énigmatique qui a stimulé bon nombre de scientifiques, pour beaucoup embryologistes, y compris Thomas Morgan avant qu’il ne jette son dévolu sur la drosophile. Longue vie aux axolotl et tritons !

Nicole SharpFrog Kick
A toad swims across a pond in this award-winning image from photographer Paul Hobson. The shot was actually captured from below the water, with the camera kept dry in a glass housing. Although the frog appears to be mid-leap, the light-distorting ripples around its feet hint at the flow its kick generated. It’s reminiscent of the vortices left by water striders as they move.

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.

C’est l’histoire d’une traversée épique et d’une belle leçon de sécurité maritime. Une scène racontée et sublimée par les photos d’un peintre officiel de la Marine qui traquait la tempête Goretti, jeudi, à la pointe bretonne, au Conquet (29).

Piia BartosWho 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.
