Do you remember when people were saying "I think my phone is listening to me, i'm getting ads for stuff I spoke about" and people said "They arent listening to you, they're just this good at predicting your interests"?

Well, it happens they were doing exactly that.

Watercolour drawing (quite large) of the garden a couple of summers ago. A very hot year and we had a good crop of plum tomatoes.

#OTD in 1849, Elizabeth Blackwell received her MD from Geneva Medical College becoming the first woman in the US to earn a medical degree.

#OTD in 1911, Marie Curie was proposed for membership in the French Academy of Sciences--and promptly voted down. 11 months later she won her second Nobel Prize (Chemistry).

51 years later, Marguerite Perey (a student of Curie), became the first woman member of the Academy. #WomenInSTEM

I learned about this dark side of syphilis when I took a history of medicine course. It is a remarkably resistant disease that brought armies to their knees and wrought tremendous societal damage.

Ancient DNA Reveals Twisted Roots of Syphilis Go Back 5,500 Years
The first known outbreak of syphilis in Europe began at the turn of the 16th century, but on the distant continent of South America, the pathogen's history goes much deeper than that.

Yes yes, ruins, palaces, mosaics, gold coins, jewellery, all very impressive, but a prehistoric ladder and a mysterious structure makes me just as happy!

The sleep patterns of jellyfish and sea anemones share similarities with those of humans, according to research published in Nature Communications. The findings support the hypothesis that sleep evolved across a range of species to protect against DNA damage. 🧪
DNA damage modulates sleep drive in basal cnidarians with divergent chronotypes - Nature Communications
Here, the authors use the diurnal upside-down jellyfish and the crepuscular starlet sea anemone as simple nerve net models to examine the potential evolutionary origins of sleep. They describe and define sleep patterns in these species, finding that sleep deprivation increases neuronal DNA damage and that sleep facilitates genome stability.
