A bit late to the
#skyparty
but I was really glad to co-chair our special symposium on protist traits at
#ICOP2025
organized by
#ISOP
in Seoul ๐ฐ๐ท Grateful for the inspiring talks, engaging discussions, and the chance to reconnect with old friends and colleagues from around the world.

Today is the last day of

! It was a blast, I enjoyed it a lot, feel very motivated, met and talked with plenty of fellow scientists, but also regret I couldn't discuss with even more people! Until next time :)

Here you will find a great overview of genomic tools and their application on protists. Figure 3 is crazy interesting for everybody who wonders about what kinds of protist genomes are available, their sizes and why there aren't more. Take a look! Glad I could contribute :)

Glissomonads (Cercozoa, Rhizaria) are always in for a surprise! Saprotrophic, sucking up bacteria lysate. Axenic culture!

Big thanks to
#OpenAI
and
#ChatGPT
-not for helping me write my manuscript, but for clearly writing one of the reviewer's entire review!๐ Never thought Iโd get peer-reviewed by a Large Language Model with imposter syndrome. Some recommendations are hilarious๐

Evidence for

, and maybe
#meiosis
, in free-living
#Rhizaria
! I wish the results were clearer. As so often we raised more questions than we could answer :) If you are into

and the
#meiosis-toolkit
, this is an important read!

Very proud to announce that my first (shared) doctoral student, Dr. Jule Freudenthal, finished her doctoral studies! ๐ She did amazing work! I know my recent shift to a professorship is for certain parts due to her work. We both align very well which is why I am happy that she is now my postdoc :) ๐

Have you used

in the past to analyse your
#ecology
data? Have you wondered how many of those correlations actually represent interactions between
#microorganisms
? Here I present a paper how we leveraged
#protistsonsky
to evaluate the validity of the method. A thread:

Netzelia corona is an amoeba with teeth. Can a model proposed by Kenneth Dumack and colleagues explain that? A brief blog post.

HUGE NEWS :) We got a project funded to work on the diversity of
#Arctic
Cryomonadida (
#Rhizaria
), i.e.
#parasite
-like predators of ice
#algae
:) One reviewer touched my heart: "I would hope that the success of the project will aid in propelling them to a permanent position." Me too, reviewer 1! ๐
