Don't you guys love this time of the year when you basically heat shock like E. coli when walking into a warm building after walking outside in the cold???

Poppies are a symbol of remembrance on Armistice Day. Did you know that some poppies are also the source of powerful opioid painkillers?

My wife has volunteered at a local food bank for years and confirms what many of you have probably heard: in this case, straight cash is a good donation if you can do it.
The food banks have better access and buying power than individuals do, and can try to address item imbalances as they see them.

Maud Menten was born in Canada in 1879 and completed her UG and MD education at University of Toronto. As a research assistant with Leonor Michaelis in 1912, they wrote the classic paper describing the “Michaelis-Menten” model of enzyme kinetics.. #WomenInScience

From descriptive to quantitative biocatalysis - Nature Catalysis
The 1913 study ‘Die Kinetik der Invertinwirkung’, by Michaelis and Menten, marked a pivotal advancement in enzymology by illustrating the application of mechanistic models and quantitative kinetics to biocatalysis. The foundational framework described back then continues to have a strong impact on enzymology, with profound influences that range from undergraduate education to structure–function studies and the format and content of contemporary kinetic databases.

Would you pay $150 per article to post your preprint on @bioRxiv @aRxiv @medRxiv @chemRxiv etc.? Currently it’s free but a small cost could help offset running costs and also work as a barrier against paper mills and AIs just posting all the time and filling these sites up.
