Thanks, yes at the moment it's divided between Bio and methods for the home page. That classification is still manual while most of the rest of the website is fairly automated. I will have to think about your idea ☺️

My advice is not to be afraid to try things out. A postdoc is like any job: if you do not like it, leave. Find a place with a rich scientific environment and a city you want to live in. Also think about what you want from your postdoc: teaching, methods, topic, connections.

Immune cells are fascinating 🤩 . Here, an embryonic myeloid cell (pre tissue-resident mac) ( 🔴 ) is seen in its (almost) natural tissue environment ( 🔵 ) of ectodermal cells. The cell is in a 2.5D-3D environment and looks it is being "swallowed up" by the surrounding cells 😁. #FluorescenceFriday.
