AI is impacting academia...but not how you expect. | Marissa Civic

AI is impacting academic student work but not in the way you might think. Here's my perspective on why it's not as simple as students utilizing AI to complete assignments: 1. Students who cheat will ...

Geneticist Irene Ayako Uchida (1917-2013) 🧪🐡👩🏻‍🔬🧬 #histsci #ald26 #AdaLovelaceDay

Happy birthday to Canadian 🇨🇦 geneticist Irene Ayako Uchida (1917-2013)! 🧪🐡👩🏻‍🔬 #histsci In my #linocut Uchida is shown surrounded by chromosones, with anomalies (pink arrows) due to radiation exposure, based on one of her research papers. A strand of DNA is hidden in the image (as her watchband).⁠ 🧵 ⁠

Linocut portrait of geneticist Irene Ayako Uchida (handsome, middle age woman of Japanese heritage with curly hair with a white streak on her right temple, with an open, thoughtful face) leaning on folded arms in a white button down shirt with a small watch with double-helix watchband on her wrist, in dark teal-grey ink. She is surrounded by chromosomes in gold, from one of her papers. The anomalous ones are pointed out with small pink arrows

This #BlackHistoryMonth let’s celebrate trailblazing American #biochemist Marie Maynard Daly (1921-2003), 1st Black woman to earn a PhD in #chemistry in the US! 🧪🐡👩🏾‍🔬 #histsci She made important research contributions to the biochemisty of the cell nucleus & cardiovascular issues & our knowledge of 🧵

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.

For #printerSolstice2526 prompt 2: my #linocut of trailblazing #microbiologist Esther Lederberg (née Zimmer, 1922-2007) 🧪🐡👩🏼‍🔬 #histsci who made discoveries fundamental to modern understanding of bacterial gene regulation, recombination & exchange, but her work was both overshadowed by & sometimes 🧵

My lino block print shows a portrait of a woman in indigo, Esther Lederberg, with curly short hair in a 1940s hairdo, lab coat with collar and gloves, holding a Petri dish vertically in each hand in front of her. Each Petri dish in bronze has the same pattern of marks. She is surrounded by silvery green E. coli bacteria of exaggerated size, several which are being attacked by bacteriophages. Both lysis (phages reproducing inside cells, then exploding out of cells) and lysogeny (genetic material indicated by gold section of tangle of DNA is quietly integrated into that of the cell). The plasmid shown in some but not all E.coli alludes to the bacterial fertility factor F.

Botanist and cytogeneticist Barbara McClintock (1902-1992) 🧪🐡👩🏼‍🔬🧬 #histsci #ald26 #AdaLovelaceDay

Ele Willoughby @minouette.bsky.social

This is my lino block print of American botanist, cytogeneticist and 1983 Nobel laureate in Physiology or Medicine, Barbara McClintock (1902-1992) with some maize. 🧪🐡👩🏼‍🔬🔬#histsci McClintock, who received her doctorate in botany from Cornell in 1927, studied the cytogenetics of maize and how their 🧵

My 11” x 14” linocut portrait of Barbara McClintock (here a middle-aged white woman with short hair and glasses) is wearing a lab coat over her button down shirt, with strand of pearls and is seated, taking notes at her binocular microscope, smiling at the viewer. She is printed in a vertical gradient from top to bottom of brown, through green to blue. The background is filled with four ears of corn or maize in various pale yellows with various kernels in brown or speckled brown.

Thanks Dr. Todd, Nice to know the C15 (PA) fatty acid is saturated 🧪🧬and acts as a "statin" or HMG-CoA enzyme inhibitor affecting the mevalonate (isoprenoid) pathway but does PA also alter HMG-CoA reductase mediated (lipo)protein prenylation or ubiquitination/degradation of the enzyme itself ?
