We are looking for a PhD student to work on an exciting plastid endosymbiosis in microbial eukaryotes. This position involves sampling, exciting microscopy such as CARDFISH, ExM and FIBSEM, single-cell transcriptomics and more. #protistsonsky 1/2

Cool! 😊

Phage "satellites" that produce capsids but have no genes to produce tails have puzzled scientists for a long time. These are abundant as prophages in bacteria, but it was unclear how they can infect without tails Now, Penadés & co show that they hijack tails from other phages. Incredible!

Please help me identify these. They are of freshwater origin and have chlorophyll.

New short paper from our lab @currentbiology.bsky.social, in which we discover of a new mode of cell motility for choanoflagellates: flagellar gliding. www.cell.com/current-biol... - A 🧵

Congrats to all grantees but a special 👏 to @messorensen.bsky.social. It’s always so nice to see past lab members go on to great successes. Also this is not the first time that my department (dept of Organismal Biology) is the only department at #UppsalaUniversity receiving an ERC grant

Check out our new paper on adopting a trait-based framework for protist diversity! We make the case for a unified protist trait database, how to build it, and how it could transform research on protist ecology and evolution. #protistsonsky
