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

My linocut portrait of Marie Maynard Daly in purples (she’s a young m, smiling Black woman, wearing earrings, a necklace and a dress, looking at the viewer over her shoulder). Above her to the right is an anatomical heart with a blowout diagram in a circle of a clogged artery and the cholesterol molecule all in red. Next to her on the left in blue are the molecules of the bases which make up DNA and a diagram of a human cell.

This is a 440-pound heart from a blue whale, the largest known animal to ever exist. The heart was so large that technicians had to douse it in 1,000 gallons of formaldehyde. Read more about it here: https://www.smithsonianmag.com/travel/painstaking-process-preserving-blue-whales-heart-180964038/
