Oooeeee! The Mosquitoes of London... Ooooeee! the Mosquitoes of London.
How does life evolve to adapt to modern cities?
Out now in Science, my PhD work with @lindymcbr.bsky.social uncovers the ancient origin of the “London Underground mosquito” – one of the most iconic examples of urban adaptation.

This is a great image. Looking at an explanatory poster in Northumberlandia Park, overlooking Shotton Open Cast Mine, ca 2017. The deep pit was by then right next to the top of the hill in Northumberlandia. Kids!You can identify the trucks!

🧠🌟🐭 Excited to share some of my postdoc work on the evolution of dexterity!
We compared deer mice evolved in forest vs prairie habitats. We found that forest mice have:
(1) more corticospinal neurons (CSNs)
(2) better hand dexterity
(3) more dexterous climbing, which is linked to CSN number🧵

Good grief! I've had an alphabetic list of US visas (F2, F1, J1, H1B and two green cards) over the years. If I had happened to have been out of the country on my H1B, I would have had 1 day to get back to the USA. Also, I or my university would have to have paid $100K/yr. From immigration lawyers:
