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.

Rosalind Franklin was born #OTD in 1920. She was a chemist and crystallographic who made a key contribution to the discovery of the double helix structure of DNA: www.compoundchem.com/2017/07/25/f...

I am so excited about this meeting. I will cover the discovery of 10,000s new metabolites, including an entirely new class of molecules. Looking forward to hearing and discussing your science on microbiome metabolites and metabolism.

This is figure 1, which shows the exploration of global venoms for antimicrobial discovery.

A study in Nature Communications used AI to mine global venom proteomes and discovered novel peptides with antimicrobial activity. Several candidates showed efficacy against drug-resistant bacteria in laboratory and animal tests. go.nature.com/4f0zYb4 #medsky 🧪
