Could recent information about dark energy fundamentally alter our understanding of the universe? It's possible. Here's a deep dive into what dark energy is and how new results on the expansion history of the universe may change everything we thought we knew.
Happy birthday to #paleontologist Mary Anning (1799 –1847)! She was the wrong class, sex & religious denomination to gain the education, opportunity to work & communicate her results or garner any respect as a pioneering paleontologist. Further, during her lifetime most people thought Earth was a mere few thousand years old, based on a very literal interpretation of the Bible & found the idea of extinction did not fit in with the story of creation. 🧵1/ #linocut#sciart#womenInSTEM#printmaking
What should Melinda French Gates do now that she’s announced her departure from the Bill and Melinda Gates Foundation? How about fixing the tech industry’s broken “brilliant jerk” culture? Tech Crunch’s Julie Bort elaborates. https://flip.it/SdsCmi #Tech#GatesFoundation#Technology#Women#WomenInStem
Why were the northern and southern lights so visible over the past weekend? Let's talk about the sun's solar cycle, solar maximum, what causes the northern lights -- and even a conspiracy theory that the aurora were artificially created.

Her posthumous books featured her "wild and fearless life," but she was also a trailblazing famous #Victorian#lepidopterist, published in The Entomologist's Record and Journal of Variations, expert on tropical butterflies, discovering, documenting, breeding & gathering specimen in 60 countries, talented scientific illustrator, 🧵 #printmaking#womenInSTEM#histstm
Happy birthday to founder of modern nursing, social reformer, statistician, data visualization innovator & writer Florence Nightingale (1820 – 1910)!
Nightingale earned the nickname "The Lady with the Lamp" during the Crimean War, from a phrase used by The Times, describing her as a “ministering angel” making her solitary rounds of the hospital at night with “a little lamp in her hand”. 🧵1/n

Happy birthday to #astrophysicist Cecilia Payne-Gaposchkin (1900-1979), trailblazer for women in #astronomy who discovered that hydrogen and helium are the most common elements in the universe.
Born England, she won a scholarship to Newnham College Cambridge in 1919 where she heard a lecture which changed her life. She wrote, “My world had been so shaken that I experienced something very like a nervous breakdown.” 🧵
#OnThisDay, 9 May 1922, the International Astronomical Union formally adopts Annie Jump Cannon's stellar classification system. The principles in it still underpin modern classification.
Visited the #Curie museum (#MuseeCurie) in #Paris today. It's tiny, but really cool to see this collection on the lives of the Curie family with their three Nobel prize winners. And you can see Marie Curie's office and lab from the time when she was head of the Curie Laboratory!
Also: A quarter of her staff of ca. 40 people were women! In the 1930's! #WomenInSTEM
#OnThisDay, 20 Apr 1902, Marie and Pierre Curie refine radium chloride. The discovery leads to Marie being the first woman to win the Nobel Prize for Physics in 1903.
The Academy originally planned to award only Pierre and Henri Becquerel. Pierre insisted that Marie should also be included.

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 geneticist Irene Ayako Uchida (1917-2013)! She is shown surrounded by chromosones, with anomalies (pink arrows) due to radiation exposure, based on 1 of her research papers. A strand of DNA is hidden in the image (her watchband).
Uchida didn’t set out to be a scientist. She was studying English literature at UBC, before she was interned with other Canadians of Japanese heritage during WWII. 🧵1/
#OnThisDay, 8 Apr 1959, Mary K Hawes initiates a project to create the first universal programming language for computers used by businesses and government. Grace Hopper led the team that then created COBOL. Some mainframes are still using it.
