Ooooh. Cool new paper on origins of life. A simple 45-nucleotide RNA molecule that can perfectly copy itself. www.science.org/doi/10.1126/...

A small polymerase ribozyme that can synthesize itself and its complementary strand

The emergence of a chemical system capable of self-replication and evolution is a critical event in the origin of life. RNA polymerase ribozymes can replicate RNA, but their large size and structural ...

paper alert🚨 Monovalent pseudo-natural products supercharge degradation of IDO1 by its native E3 KLHDC3 - Published by the groups of Herbert Waldmann @waldido.bsky.social , Slava Ziegler and @georgwinter.bsky.social @cemm.oeaw.ac.at in @nature.com Chemistry www.nature.com/articles/s41...

Monovalent pseudo-natural products supercharge degradation of IDO1 by its native E3 KLHDC3 - Nature Chemistry

In targeted protein degradation, a degrader molecule brings a neosubstrate protein proximal to a hijacked E3 ligase for its ubiquitination. Here, pseudo-natural products derived from (−)-myrtanol—iDeg...

This week's #RDKit blog post shows how to create simple protein--ligand interaction diagrams. I think there's potential to take this a bit further... greglandrum.github.io/rdkit-blog/p...

“We only have a few minutes left so please keep your questions brief.” “Thank you for your talk, before I ask my convoluted question and get to the point, please allow me to tell you my name, title, position, rank and academic biography…”

OpenAI just updated ChatGPT to be able to use RDKit, a cheminformatics Python package. OpenAI's president says this makes ChatGPT "useful for scientific work across health, biology, and chemistry," but it is hilariously still not good at chemistry (🧵) #chemsky #AI ⚗️🧪🖥️

I will soon be posting a postdoc position in protein biochemistry/biophyics! Interested candidates are welcome to reach out at luclar@kemi.dtu.dk. Experience in protein expression, purification, and assay development is a must. Structural biology would be great! Please RT :)

Rxn-INSIGHT also has some functions for molecules, but many more for reactions. Functional groups and rings are handled separately here: github.com/mrodobbe/Rxn...

We had discussed internally some time ago, that the fact, that all SELFIES encode for valid structures might be detrimental to machine learning. A Nature machine intelligence article now seems to confirm this: www.nature.com/articles/s42... #ChemInformatics

Invalid SMILES are beneficial rather than detrimental to chemical language models - Nature Machine Intelligence

Generative models for chemical structures are often trained to create output in the common SMILES notation. Michael Skinnider shows that training models with the goal of avoiding the generation of inc...

This is really driving me crazy: My boss does not want me to leave, I don't want to leave, but still I have to leave at the end of the year, because of the #WissenschaftsZeitvertragsGesetz. So today I reviewed the upcoming job posting for my successor, who should have exactly my qualifications.
