#tbt "My work is what will survive", she said. She co-authored this 1945 book, with chromosomes of over 10,000 plants. Magnolias that botanist & cytogeneticist Janaki Ammal planted at RHS around then survive too, including this one named after her ...1/9 natsca.blog/2019/04/26/my-… ImageImage
...E.K. Janaki Ammal (1897-1984) was 10th of 19 children in a mixed-race family in Kerala, India, with caste adding to the discrimination in her life. She chose a life in science over a planned marriage & her achievements are the stuff of legends thebetterindia.com/75174/janaki-a… ...2/9 Image
...Janaki earned a master's degree in botany from the University of Michigan in 1925. She returned on another Barbour scholarship to become the first woman to earn a PhD in Botany there - & they conferred an honorary doctorate in science to her too...3/9 en.wikipedia.org/wiki/Janaki_Am… Image
...Hard to imagine the barriers she overcame. She was detained at Ellis Island once, released when someone mistook her for an Indian princess: she was wearing traditional silks...“I did not deny it”.
In 2018, a rose with the colors she so often wore was named after her...4/9 ImageImage
...In the US, she developed an eggplant called Janaki Brengal. Back in India she worked at the Sugarcane Breeding Station, evolving major breeds of sugarcane that could be grown in India: she's known as the woman who made Indian sugarcane sweet...5/9 alchetron.com/Janaki-Ammal
...Facing caste & gender discrimination, though, she moved to London, joining CD Darlington at the John Innes Horticultural Institute, & worked on flowers & ethnobotany, & that atlas of chromosomes...6/9 scroll.in/article/730186… Image
...Janaki was headhunted by the RHS (Royal Horticultural Society) & was the 1st female scientist they employed. She published papers, worked on medicinal plants, traveled internationally & collected specimens, exhibited at the Chelsea Flower Show - & planted those magnolias...7/9 ImageImage
...Janaki met Nehru - as in, the Prime Minister of India - on a plane. He lured her back to head the Botanical Survey of India in 1952, where she led the creation of an inventory of India's plant resources, & was a professor too. A Gandhian, she lived an ascetic life...8/9 Image
...Janaki became a powerful advocate for indigenous plants & biodiversity. At 80, she lent her influence to a community movement to prevent a dam being built in Kerala. A national park ensured it remains an undisturbed home to endangered species. 9/9 smithsonianmag.com/science-nature… Image
...PS: oops - I left out, the first RHS employed there at Wisley. Which gives me another excuse to show Magnolia Kobus Janaki Ammal! Image

...FDA report on Friday lists 6 cases in vaxed arms of 2 trials, 4 of which don't have a specific possible alternative cause identified. This was versus 1 in placebo (not injection-related). The 2 trials had ca 27,000 vaxed participants... fda.gov/media/158912/d…

#tbt This is Toshiko Yuasa, the first woman physicist from Japan. It's 1940 & with her science prospects at home blocked by gender prejudice, she'd managed to get into wartime Paris to do physics research... en.wikipedia.org/wiki/Toshiko_Y…
...The drawcard in Paris was Marie Curie's daughter, Irène Joliot-Curie & her husband Frédéric. Yuasa was inspired by their papers on artificial radioactivity.
Here's Toshiko & Irène at the Joliot-Curie home in 1941... en.wikipedia.org/wiki/Ir%C3%A8n…
...Yuasa was born in downtown Tokyo in 1909, the next-to-youngest of 7 children. Her mother came from a long line of poets, in the family of a renowned 19th century scholar, Tachibana Moribe. Her father was an engineer & inventor who worked at the patent office...

When it hit me that I knew nothing about early women scientists in Ukraine, I went down a mind-blowing rabbit hole...

Such terribly sad news: the loss of Chris Del Mar, a giant of the Australian – and global – evidence community.
💔 for Tammy & family.
You'll hear a lot about this wonderful, lovable person & his amazing life ....
...Here's a quick overview from late last year, when Chris was awarded the Order of Australia - one of my faves because of the lovely family photo.... www1.racgp.org.au/newsgp/profess…
...I want to add to the remembrances & accolades for Chris, memories of a specific stream of his life - patient empowerment. From back in the early 2000s when we used to use this photo. He was the Chair of the Board of the consumer health information NGO I headed back then...

1st Covid human challenge trial results shows it is feasible: 34 people were inoculated with a very low dose. It was enough to infect 18 people (53%) & 89% of them developed symptoms ...🧵 researchsquare.com/article/rs-112… HT @HelenBranswell
..Viral shedding quantifiable within 40 hours. They concluded up to 44% of infections would happen before virus can be detected. Results support 10-day isolation periods & professionally-administered LFA/RAT was "highly reliable in predicting the disappearance of viable virus"...
...The people were 18-29 years old, & stayed in individual negative pressure quarantine rooms. No safety signals in these first 28 days of follow-up. (They'll follow them for a year)...
