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.

Genuinely delighted to download a PhD thesis from a university repository where the author has neglected to remove the words "BITCH THIS IS YOUR THESIS" from the filename.

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 β€œMichaelis-Menten” model of enzyme kinetics.. #WomenInScience

From descriptive to quantitative biocatalysis - Nature Catalysis The 1913 study β€˜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.

It’s blocked by a frog! A frog’s face is glaring at me from inside the green watering can.

Tried to water the baby asparagus but the spout was blocked so I tried to shove the blockage down into the can but the thing inside shoved back.

Today in Chemistry History graphic on Rosalind Franklin and the structure of DNA. Rosalind Franklin was a chemist and  X-ray crystallographer whose work was instrumental in the discovery of the structure of DNA. She missed out on a Nobel Prize for her work as they are not awarded posthumously. Photograph 51 is an X-ray diffraction image of DNA taken during Franklin’s research. It was crucial in developing a model of DNA and confirming its double helical structure.

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.
