Nettie Stevens, the scientist who never got credit.
Recognition doesn’t always follow achievement.

Her work changed how science understands biological development, yet her name rarely appears.

#Genetic Scores are Booming. But Will Anti-Discrimination Laws Cover Your #DNA ?

A scanning electron micrograph of human #chromosomes. #Polygenic risk scoring, increasingly popular in personal #medicine , uses an individual’s #genome to estimate that person’s likelihood of developing a specific #disease.

Happy birthday to Canadian 🇨🇦 geneticist Irene Ayako Uchida (1917-2013)! My #linocut is hand printed on 9.25” x 12.5” Japanese kozo (or mulberry) paper. Uchida is shown surrounded by chromosones, with anomalies (shown with 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).⁠

"Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male determination, it was thought this loss would not affect health.

But evidence has mounted over the past few years that when people who have a Y chromosome lose it, the loss is associated with serious diseases throughout the body, contributing to a shorter lifespan."

Before #cells can divide, they first need to replicate all of their #chromosomes, so that each of the daughter cells can receive a full set of #genetic material. Until now, scientists had believed that as division occurs, the #genome loses the distinctive 3D internal structure that it typically forms.

Why do #women outlive #men? A study of 1,176 species points to an answer.
Body of evidence suggests women's #longevity may derive, from having double X #chromosomes, a redundancy that protects them against harmful mutations. The most sweeping analysis to date of #lifespan differences between males and females in more than 1,000 #mammal and #bird species.
“From a #human standpoint, it’s really remarkable that women live longer across almost every country in the world”

#DidYouKnow: #Cytogenetics refers to the study of tissue, blood, blood marrow, or culture cells in a laboratory, using banding or manipulating techniques to look for changes in the #Chromosomes, including broken, missing, rearranged, or extra chromosomes.

Changes in the chromosomes may be a sign of a genetic disease or condition

"#spores of S. sclerotiorum contain one set of 16 #chromosomes divided across two nuclei, rather than each nucleus containing a complete set... #chromosome composition varies among nuclei, suggesting the division of chromosomes between nuclei is in an irregular manner... to produce the next generation, they need to reform a diploid cell with the full suite... Presumably, this requires the fusion of nuclei"
