- Reposted by Thijs J. G. Ettema 🦠🔬🇳🇱🇸🇪🇪🇺Just on time for the holidays! Happy to share the published version of the discovery of leptophytes, a new deep-branching and widespread group of microalgae based on plastid MAGs (ptMAGs). Now with additional support from a mitochondrial MAG (mtMAG) of leptophytes. www.nature.com/articles/s41...

- Yesterday it was 20 years since I defended my PhD thesis! I have struggled my way through the academic system, with times when I was about to give up due to lack of funding and support. I am proud where I am now, and what I have achieved. Thanks to everyone who supported me and believed in me!

MEME is a fantastic 2-year MSc between four European Universities on all areas of Evolutionary Biology. Apply and study in Sweden/France/the Netherlands/Germany/USA/Switzerland! www.evobio.eu
- Reposted by Thijs J. G. Ettema 🦠🔬🇳🇱🇸🇪🇪🇺Interesting how companies and the financial world is racing to spend mindboggling amounts of money to build the infrastructure to train computers. But we are leaving the infrastructure to train and educate humans crumbling. The question is who will train who?
- OK, somebody should say it: the term 'one-stop-shop' has no place in academic research. Due to their diverse and exploratory nature, there is no single solution for scientific projects - else this would be routine research. RT if you agree, or feel free to argue otherwise below.

- In 2015 we discovered 'Loki', the first member of the Asgard archaea, the closest relatives of eukaryotes. Did you know that in stead of Lokiarchaea, we considered the name Eoarchaea. 'Eo' after Eos, the greek goddess of dawn, and in reference to the eocyte hypothesis for the origin of eukaryotes.
