Unpicking the Mystery of the Body’s ‘Second Brain’
Sitting alongside the neurons in your enteric nervous system are underappreciated glial cells, which play key roles in digestion and disease that scientists are only just starting to understand.

People might not realize - this wasn’t just one problematic person. He was (and is) influential. And this has real consequences.
“Female scientists who have kids can’t be taken seriously” and many other jabs at women have been directly said to me, within the last decade, by other scientists.

I read this book when I was 15 and fell in love with DNA. I re-read it at 32 with lived experience in Science and it filled me with rage. I cannot pick up that book now. It reveals what women were/are up against.
Based on his self-described behavior in The Double Helix and these actions it is easy and appropriate to write him off as an ignorant jerk.

Lab’s 1st preprint!
Menstruation is understudied due to societal taboos + a biological challenge: mice (a key system for research + drug discovery) don’t menstruate.
@cagricevrim.bsky.social made menstruating mice + used them to discover early events in menstruation.
