Rare microbial relict sheds light on an ancient eukaryotic supergroup - Nature The discovery of an unusual protist named Solarion arienae, which has a mitochondrial genome with some intriguing features, provides insight into the early radiation of eukaryotic groups.

Superb pictures...

Fantastic work done with a very large number of RCC strains.

Another piece of fascinating work done with RCC strains.

Superbe....

We have added more than 900 new GenBank sequences to the RCC database that are linked to the web page of the corresponding strains.

New version of PR2 that now includes the eKOI coi database recently published.

PR2 primers version 2.1.0 has been released. This does not include any new primer, but now the database uses the latest version of PR2 (5.1.1) to perform in silico analyses.

metaPR2 version 3.0 has just been released.

Here are the major changes:
- Metabarcodes (ASVs) are now annotated with the latest version of the PR2 reference sequence database (5.1.0).
- 8 new published datasets have been added from the Arctic and from the South West Pacific.

I would never believe this would happen in a Canadian university☹️

Such statements undermine funding efforts for large scale oceanographic projects. I am sure Trump would lovet it...

The following statement is utterly misleading "The cost of this venture pales in comparison to running a scientific research vessel, while yielding far more information..." A bunch of random measurements will never replace a carefully planned cruise with a very large number of metadata.

It was so nice and so fulfilling to interact with you both...

Very nice led by Clarence and Adriana...

ASM is so US centered... mostly American authors, a few European and no one else from South America, Africa or Asia... a real shame.

We have contributed to a paper led by Kenneth Timmis on the murky world of predatory journals:

We have an A in house with a brillant master thesis defence of Sandra Irén!!! First master student of the GEEK lab in Norway! 😍 Thanks to @maritbjorbaekmo.bsky.social and Inger Skrede for a delightful & constructive discussion. #protists #proudadvisor 🔬🧬👩‍💻 @biovitenskap.bsky.social

Congratulations Puri... Is the speech available anywhere ?
