A Team of Awesome Women & the Nobel Prize

Strong women come in all sizes, colors, religions, and abilities. Today we celebrate two women who discovered one of the greatest breakthroughs in the biological sciences. Dr. Emmanuelle Charpentier and Dr. Jennifer A. Doudna were awarded the 2020 Nobel Prize for Chemistry this week for their development of a groundbreaking method for editing DNA. They discovered the genetic scissors called CRISPR/Cas9. It’s a tool that allows scientists to “snip” the DNA of organisms, “allowing for easy and precise genetic modifications.” https://www.amightygirl.com/blog?p=31760 They are the sixth and seventh women in history to win the Nobel Prize in Chemistry and the first pair of women to win the chemistry prize. This team of awesome women teamed up for a common goal, and the results are world changing. Excellence is never an accident. It is always the result of high intention, sincere effort, and intelligent execution; it represents the wise choice of many alternatives—choice, not chance, and determines your destiny. Aristotle (384-322 BC) Dr. Emmanuelle Charpentier Emmanuelle Charpentier was born on December 11, 1968 in Juvisy-sur-Orge, a commune in northern France, 18km south-east of Paris.  Charpentier studied biochemistry, microbiology and genetics at the Pierre and Marie Curie University. She received a research doctorate from […]

Should You Worry About Saboteur Genetics?

Most of us are familiar with the discomfort of a mosquito bite. And unfortunately, many of us have acquired a disease from a mosquito bite. In January 2021, the eggs of more than 750 million genetically modified male mosquitoes will be released in the Florida Keys. Their modifications create a form of genetic sabotage. Should you worry about saboteur genetics? In today’s article, we’ll discuss the mosquito, the diseases carried by this species of mosquito, and what we know about this test.  The Mosquito Life Cycle There are 3,500-4,000 species of mosquitoes. Their life cycle from birth to larva takes from five to forty days, depending upon ambient temperatures, density of larval population, and food supply. Most mosquito lay their eggs on the surface of stagnant water. Clutches of eggs of hatch as soon as possible, and all the eggs in the clutch hatch into larvae at much the same time. As larvae, they are mobile and feed on algae and organic material. Larvae develop through four stages, then they metamorphose into pupae. Pupae typically hang from the surface of the water by their respiratory trumpets. Depending on temperature and other circumstances, in a few days the adult mosquito emerges. Adult Mosquitoes Within […]

The First to Discover the Sex Chromosomes

When women rarely went to high school, Nettie Maria Stevens (1861-1912) wanted to be a research scientist. We don’t know a lot about her personal life, but she became a biologist. And though she received little credit for it during her lifetime, she was the first to discover the sex chromosomes. Before the 1900s, the link between Mendel’s genetic rules and gender were unclear. Scientists didn’t know what factors determined the sex of an offspring. Some believed external factors such as temperature and nutrition influenced gender. Very few thought chromosomal factors were responsible for the gender of offspring. Early Life Born on July 7th, 1861 in Cavendish, Vermont to Julia and Ephraim Stevens. Records of her early life are sketchy. We know her mother died relatively early in Stevens’s life but don’t know what caused her death.  Her father, a carpenter, remarried and the family moved to Westford, Massachusetts. He earned enough to send both of his daughters to high school, though it was uncommon to educate women. Stevens graduated from Westford Academy in 1880. She and her sister, Emma, were two of three women to graduate from her high school. Teacher, Librarian, and Student Stevens wanted to become a […]
