"... pus de 2 000 ans d’augmentation de la biodiversité en Europe ont été générés grâce aux humains –et non malgré eux. Mais pourquoi ? Contrairemt à aujourd'hui – où les monocultures dominent – les systèmes agricoles mixtes étaient la norme pendant la majeure partie des 2 000 dernières années

Quand la peste a décimé la population mondiale, la biodiversité a, paradoxalement, elle aussi chuté
En analysant des archives polliniques, des chercheurs montrent que l’abandon des terres agricoles a fait reculer la diversité des plantes pendant plus d’un siècle.

Trump officials are trying to sneak around federal judges’ orders. They could be held in civil contempt of court, which can include jail time and can’t be undone with a presidential pardon, according to @sbagen.bsky.social . My latest for @theguardian.com www.theguardian.com/us-news/2025...

Programmed cell death distinguishes N. gonorrhoeae & N. meningitidis from other #Neisseria species. @katyponcin.bsky.social &co identify a horizontally acquired genetic island encoding peptides that drive #autolysis & human cell lysis, aiding colonization & disease 🧪 @plosbiology.org plos.io/4aP2om9
Top: Organisation of the nap island in Neisseria gonorrhoeae FA1090. Grey arrows, flanking genes (NEIS0808, pseudouridine synthase; NEIS0794, histidyl-tRNA synthase); blue arrows, genes coding for GG-containing peptides; orange arrows, genes predicted to be involved in peptide processing and secretion; green arrow, gene of unknown function; pink boxes, Correia elements. Bottom: Transmission electron microscopy images from bacteria in HEPES (T = 75 min). Some wild-type bacteria appear normal (indicated with arrow numbered 1), with many others having a dense (arrow 2) or very dense (arrow 3) cytoplasm, periplasmic expansions (arrow 4), or appearing as ghost cells (arrow 5). Extracellular vesicles (arrow 6) and released cellular content (arrow 7) are also visible. Periplasmic expansions are not observable in the ΔltgA or ΔnapRABC strains. Cytoplasm condensation appears more homogenous in the ΔltgA mutant.

We need to have a ‘code of conduct’ for reviewing manuscripts, like (1) if you say that something is not novel then provide the reference. (2) If you propose an experiment, state precisely to which claim it is crucial. (3) If you want to say something nasty then sign your name.
