Actually the view from my office just got more interesting, as the official celebrations of the 200th anniversary now include a pirate projection saying "Free Palestine". Regardless of opinions, may UCL enjoy 200 more years of freedom of speech.

How to be a scientist in a post-journal world
When we created this site to write about things in science that need to be fixed, we chose not to start with publishing, even though it has been our preoccupation for decades.

This principle of play and inquiry is something that truly motivates me in what I do 🔬 Science is a method, a way of scrutinizing the world. We shouldn’t take it too seriously; it is a discipline, but it is also playful. 🍄✨

The lab's first paper is out! We find that pupil constriction in mice drives strong retinal activity in vivo, and that humans can also perceive pupil-shaped stimulus. This has repercussions for anybody using pupillometry. đź§µ1/n

How much analgesia is needed to manage pain levels in mice after brain surgeries? A single dose of meloxicam seems to be enough. Even the addition of opioids cannot provide a clear benefit. (in line with recent work from others, see cites in our preprint):

Tired of not being eligible for postdoc funding schemes because I don't want to move to another country to start the project. The system where scientists are required to upend their life for vague reasons of changing scientific environments is shite. Just another pointless sacrifice
