Proud of our new study out in @cp-cellreports.bsky.social! Using E. coli lacking all 8 endopeptidases, we provide direct evidence that peptidoglycan expansion during elongation requires ED-mediated insertion of one glycan strand at a time. This can be performed by MepS, MepM, MepH and PBP7 #microsky

Lucky ISPP participants, anyone wants to share some of the science you are living?

The academic community has looked at how artificial-intelligence tools help researchers to write papers, but not how they distort the literature scientists choose to cite, says Zhicheng Lin go.nature.com/45X3Imr

How do cyanobacteria glide in sync? 🌀 New research on Fluctiforma draycotensis shows that filament movement relies on tightly coordinated cellular forces, and when that coordination breaks down, the filaments twist and buckle. buff.ly/Q4l6w5y

#microsky We challenge the long-standing view that peptidoglycan alone protects cells from bursting. Our study shows that the periplasm — enclosed by OM–PG connections — acts as a pressure buffer essential for osmoprotection in Gram-negative bacteria. 📄 www.nature.com/articles/s41...

Metal ions are universally required for life, and many of the foundational principles of metal homeostasis have emerged from studies of microbial systems. In this review, I provide a introductory overview targeted to those new to the field. #MicroSky #Metals rdcu.be/eycU2

New preprint: eukaryotic origins! 🥁 We propose that iron -not oxygen- may have delayed the rise of complex life. Our model reframes the “oxygen delay” puzzle: the gap between atmospheric O2 and early eukaryotic fossils may reflect iron-mediated stress, not for O2: www.biorxiv.org/content/10.1...

No it will not become obsolete; it will never be obsolete. Even if AI fetishists keep telling us it will. Why are we willingly atrophying our minds just as fascists control more and more of our worlds?

Amazing indeed

Do girls and boys really differ in their mathematical skills? A recent @nature.com paper by @standehaene.bsky.social et al shows that French boys and girls enter school with similar abilities, but after just four months, boys pull ahead 🧪 www.nature.com/articles/s41...
