Interested in one of the top jobs in European biology?

"... 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

@erc.europa.eu-funded postdoc position in my lab to identify the molecular basis of prey-predator interactions using our favorite micro-vampire Bdellovibrio exovorus as a model.
Let's find what the bite is made of! 🧛
Flexible start date.

Un des dessins et une des découvertes les plus importantes de la physique !!! Et je vous montre l'original.
Merci à l'Academie des sciences pour leur accueil.

mScarlet3-H (aka mYongHong) is on the cover of Nature Methods! All plasmids are available for free from WeKwikGene wekwikgene.wllsb.edu.cn/publications...
Any effect on bacteria ???
Exciting times for protein science! 🧪
Are there any bacterial pathogens specific to sharks ?
I have worked with gonorrhoea before. It is very hard to handle and considered a fastidious organism. The expertise needed is real and those people indeed cannot be replaced easily.
Same. They stopped even considering applying to US labs.
Great ! Cool that it is a lasso peptide !
New preprint on how a minimal Salmonella kinase needs a host kinase to activate it. Work led by @timeshpillay.bsky.social and another great collaboration with @katrinrittinger.bsky.social @crick.ac.uk biorxiv.org/content/10.1...
Head's up: Are you NOT a scientist? Then my podcast is for you. Are you a scientist? Then my podcast IS for you too. History of chemistry 🧪 is not taught to chemists, whether undergrad or grad. (I also appreciate support to keep going through my Patreon page.) thehistoryofchemistry.buzzsprout.com
🔥📢Didier #Raoult a déposé PLAINTE CONTRE MOI
et il le fait peut-être...sur vos impôts.
J'ai gagné, intégralement relaxé: www.lexpress.fr/sciences-san...
Mais il insiste et a fait appel. Je relance donc cet appel aux dons pour ma défense: pots.lydia.me/collect/3898...

If you don’t have an incubator, “simply” wait for late spring/summer time. You need a higher temperature in your room. 😉
Ideally at least 28 degrees Celsius (37 is the usual)… and constant if possible. Ok in the dark. Avoid touching the whole area of the plate too, so you can see the difference when it starts growing.
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 .

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.
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
A Christmas present to all of the lasso peptide connoisseurs out there. The next chapter in our work is on triculamin is ready on bioRxiv. Great work by two incredibly talented graduate students @amerrild.bsky.social and @tizianasvenningsen.bsky.social.

Attention, cascade réalisée sur X, n'essayez pas de la reproduire chez vous, c'est pour les professionnels. Des journalistes n'en ont plus rien à faire des faits, et l'on devrait débattre sur la rotondité de la Terre....
Attention, parole subversive "La Terre n'est pas plate!"
Looks good ! SOS-related gene ?
