Laura Ayres (1922-1992) was a pioneer virologist from Portugal. She set up the Portuguese National Programme for the fight against AIDS as well as the AIDS Reference Laboratory at INSA, one of the first Portuguese institutions to develop the capacity to diagnose HIV infections. #WomenInSTEM 🧪

Italian mathematician Maria Gaetana Agnesi died #OTD in 1799. She wrote the first book discussing both differential & integral calculus and was the first woman appointed as a mathematics professor at a university (University of Bologna). #WomenInSTEM #mathematics

#FossilFriday Irene Crespin, Australian micropalaeontologist, died January 2, 1980. In 1936 she succeeded F. Chapman as palaeontologist in the Department of the Interior of Australia - receiving half his salary because she was a woman #WomenInSTEM 🧪⚒️ paleonerdish.wordpress.com/2018/10/05/f...

German astronomer Caroline Herschel died #OTD in 1848 Widely considered the first 𝘱𝘳𝘰𝘧𝘦𝘴𝘴𝘪𝘰𝘯𝘢𝘭 female astronomer due to receiving a salary (1787, £50 per year). She was the first woman to receive the Royal Astronomical Society's Gold Medal (1828; 2nd to Vera Rubin in 1996). #WomenInSTEM #astronomy

Rachel Carson's book 𝘚𝘪𝘭𝘦𝘯𝘵 𝘚𝘱𝘳𝘪𝘯𝘨 (1962) documented how DDT led to thin eggshells & reproductive failure in predatory birds like bald eagles. It led to the 1972 US DDT ban, sparked environmental awareness & helped bald eagles recover from near-extinction. #WomenInSTEM It's Save the Eagles Day!

Mathematician Ruth Moufang, known for extending Hilbert's axioms for plane geometry to projective geometry, was born #OTD in 1905. The Nazis dismissed her from teaching, but she later became the first woman officially titled as professor of mathematics in Germany. 🧪 👩‍🔬

Relentless "improvement" of the countryside leaves no space for nature. But ever more people are now helping the wild return, through *rewilding*. No matter who you are or where you live, you too have a part to play in the fight. There is no better New Year's resolution.

Eamon Ryan laments how "The global tide of environmental consciousness keeps coming in and going out." Might that be partly because of (some) Greens allying themselves with the very forces behind the collapse of ecosystems, the climate, and people's living standards??? share.google/kPTPp21MSyxw...

Do not cite an academic paper unless you’ve read it

The plagiarism-droid just wants to please you, and it will do that by inventing citations, which you will love because of confirmation bias. It's not a literature review if you haven't reviewed the fucking literature. Jeez...

Devastating news that marine biologist, science communicator, and UniMelb VC Professor Emma Johnston has died after a short illness. She really was an extraordinary and visionary leader, and I have no doubt she would have made a fine Chief Scientist one day. theconversation.com/emma-johnsto...

“Climate action” is just another way to say “we want our beautiful complex planet to continue to be a good place to live, and to continue to be both beautiful and complex”. So much climate damage comes from assuming that Earth is simple, that it is easy to control and that it will bend to our will.

Over at X, Elon has added a feature that allows you to edit any image anyone has posts using AI I edited an image of a real scientific paper (left) with the prompt "change the title and images to be more fear-inducing" I can envision no ways in which this may be abused. None at all. 🧪

I can't count how many #Sustainability Walks I've led, but this is the first time weather cooperated with my own class. I've taught #environmentalscience for 3 years now, and this semester I was finally able to take my kids around campus where sustainability initiatives are hidden in plain sight! 😊
