Happy birthday to #biochemist Marie Maynard Daly (1921-2003), 1st Black woman to earn a PhD in #chemistry in the US! She made important research contributions to our understanding of the biochemisty of the cell nucleus & cardiovascular issues & the chemistry of histones & protein synthesis. She established that "no bases other than adenine, guanine, thymine, and cytosine were present in appreciable amounts" in DNA - #womenInSTEM#BlackInSTEM#histstm#printmaking#linocut#histmed#HeartDisease
Happy birthday to Canadian medical researcher & #biochemist Maud Menten (1879-1960). Not only was she an author of Michaelis-Menten equation for #enzyme kinetics, she invented the azo-dye coupling for alkaline phosphatase, 1st example of enzyme #histochemistry, still used in imaging of tissues today & she also performed the first #electrophoretic separation of blood haemoglobin in 1944!

She published original research establishing that….
“no bases other than adenine, guanine, thymine, and cytosine were present in appreciable amounts" in DNA - research which was cited when Watson & Crick accepted the Nobel Prize for the structure of DNA. She did some of the earliest work on the relationship between diet & cardiovascular health. She was 1st to show how cholesterol could clog arteries & that hypertension lead to atherosclerosis; these were invaluable discoveries in our understanding of heart attacks & work to lower the risk. 🧵2/n
the National Technical Association recognized Daly as one of the top 50 women in STEM. She was devoted to playing the flute, gardening & her dogs; when her cancer made flute playing difficult, she learned the guitar. She died in 2003, at the age of 82, in New York City.
Birth Anniversary of English #Biochemist Frederick Gowland Hopkins (1861). He was co-awarded the Nobel Prize in Physiology or Medicine in 1929 for the discovery of #Vitamins.
A #Trojan is a small celestial body (mostly asteroids) that shares the orbit of a larger one, remaining in a stable orbit approximately 60° ahead or behind the main body.
In the Solar System, most known trojans share the orbit of Jupiter. In other planetary orbits only nine Mars trojans, 28 Neptune trojans, two Uranus trojans, and a single Earth trojan, have been found to date.
