Oxygen gradients shape E. coli motility patterns as they run away from O2! - 😍

Asked similar question before but I try again. Anyone knows proteins that localize like this? This protein is present in diplonemids/bodonids/euglenids/Naegleria, which have two flagella, but not in trypanosomatids that have just one flagellum. Potentially interesting for flagella/cilia community?

We have posted our new #preprint regarding the track recognition mechanism of dynein-2 that works in #cilia on bioRxiv @biorxivpreprint.bsky.social!! www.biorxiv.org/content/10.1... 1/8 🧵

Dynein-2 is tuned for the A-tubule of the ciliary doublet through tubulin tyrosination https://www.biorxiv.org/content/10.1101/2025.01.27.635025v1

It’s interesting that all versions of Alphafold distort large extended proteins to ‘globularise’ them. It’s fine for people that understand those helices are ‘bent’ but for non experts it’s confusing. 🫤 🤔 It happens a lot and isn’t well discussed in the community.

Proud to be part of this paper published in @naturecomms.bsky.social. Using high-speed AFM, we have visualized the real-time translocation of substrate polypeptide by the single molecule of SecYEG-SecA!!! Please check this amazing video taken by high-speed AFM!!! www.nature.com/articles/s41...

Happy New Year from the northside of Japan🌅🎍❄️

Did you know #diatoms are motile? These tiny glass cells have no cilia or flagella and a rigid body yet can glide on surfaces using a specialised slit in the cell wall called the raphe! What is the functional morphology of the raphe? All revealed in our new preprint www.biorxiv.org/content/10.1...

12月1日から、国立遺伝学研究所の所長として赴任しました近藤滋です。 日本の基礎科学を盛り上げるために、精一杯働く所存です。皆さん、ご協力をお願いいたします。 所長挨拶： www.nig.ac.jp/nig/ja/about... 学生へのメッセージ： www.nig.ac.jp/nig/ja/phd-p... どちらも、楽しく読んでいただけるように書きました。特に、学生へのメッセージの方ができが良いので、まずそちらからお読みいただけますと幸いです。

Hey researchers (especially non-native speakers of English), do you use generative AI to write papers? If so, how do you (or how should we) acknowledge it? I haven't, but am thinking how to write next one.

Mitosis in a green alga. The cell grows until it is tetralogy, then divides twice to form 4 new haploid cells. This is one of my study algae, Oophila amblystomatis, a symbiotic green alga. #protistsonsky #protistaday

I already talked to some people, but as a member of Associate Editorial Board of Cytoskeleton Journal, I am putting together a special issue "Structures of microtubules and microtubule-related proteins". #microtubule #structure #cytoskeleton

As a new PI (had a lab in this summer), I'm also wondering: in what case to post arXiv/bioRxiv and in what case not to? Probably different between biology/physics and theory/simulation/experiment...🤔

Was trying to obtain #bioRxiv information and automatically write into Discord using #Python . Want a Raspberry Pi to run regularly. Keyword extraction by Spacy does not always work... #pyladies
