This is really interesting. Research shows that the Black Death acted like an important selective pressure mechanism to the evolution of immune system. The magic is in ERAP2. The variant rs2549794 gives us the advantage of enhancing immunosurveillance. 🧪 news.uchicago.edu/story/ancien...

#Martian geology The documentary power of the Atacama Desert contrasting sharp eroded salt mountain ridges with a massive smooth sand dune An artistic study of extreme textures and arid scale under a clear sky #luiscordobapharchive #atacama #chile #landscape #desert #geology #travel #EastCoastKin
Horizontal orientation landscape photograph capturing the extreme topography of the Atacama Desert in Chile. The foreground and midground feature highly eroded, rugged clay and salt rock formations with deep ridges and shadows in reddish-brown tones. Rising behind these jagged textures is a massive, smooth sand dune sweeping across the upper right. In the far distance, blue mountain ranges sit under a clear blue sky. The sunlight emphasizes the stark contrast between the sharp geological ridges and the soft contours of the desert sand. Optimized for Atacama desert geology, Valle de la Luna landscapes, eroded rock formations, and South American arid geography indexing.

We are. We're talking about all male violence, about any and males who breach women's and girls boundaries, about the systemic and social prioritising of men's feelings and careers above women's lives. We're talking about men - it inevitably includes those men who wish they were women.

I'm especially fond of this one she did of The Bear busking in my kitchen in Norfolk in 2013. The Bear was always "The Bear", NEVER "Bear". That would have been a very different cat. (People who still call him the latter tend to be people who followed the Twitter account but never read about him.)
