Yes well said!! "Behaviourally complex"!!

Time we finally recognised that you don't need to be a "higher" animal to exhibit behavioural complexity...
🦠 Neither plant, animal, nor fungi: protists are beautiful, bizarre, and behaviourally complex.

For @sallywarring.bsky.social and @santa-walker.bsky.social at Earlham Institute, they're creating some fascinating scientific challenges.

1 budget for 26-30 is rising 🎉
2 quota for basic research stable 🙂

BUT

3 we're slashing success rate for currently assessed grants 🫠
4 next call hopefully in Apri 2027 (with £s for lucky few going out months later, suppose) 💀

How does this make us more competitive?

New paper out in @bmc.springernature.com 🤩👏 A routine 5-ethynyl uridine (EU) RNA labeling experiment in a sea anemone turned into detective work for @malinkjosavik.bsky.social, @ktgarschall.bsky.social & @prhsteinmetz.bsky.social 🕵️‍♀️
A widely used RNA assay labels the wrong molecules in several model organisms
After a routine experiment raised suspicions, Steinmetz group researchers joined forces with collaborators to highlight the limitations of a commonly used RNA labeling product.
