Wooow! Its so cute!
I can't wait to be able to run RT-qPCR in my lab!!!
Eagerly awaiting my Pocket qPCR to arrive. I can finally use my 50k units of reverse transcriptase I got from Gene and Cell Technologies a few years ago.

Happy to share a new preprint from the lab: Marko became interested in whether the disordered linker of FtsZ might influence how the protein organizes into the Z-ring. And this led to some surprising findings!

Charge segregation in the C-terminal linker of FtsZ enables Z-ring scaling with prokaryotic cell width
Bacterial cytokinesis is orchestrated by the Z-ring, a cytoskeletal structure formed by treadmilling filaments of the tubulin-like GTPase FtsZ. During assembly, filament curvature must match the cell ...

Maybe baby dragons are blond like cats
Olms (Proteus anguinus) look like you took an axolotl & stretched them out. 'Dachshund axolotls', if you will.
They're a cave-dwelling salamander that live deep under the Alps of Central Europe. When floods flushed them out to streams, they were described as 'baby dragons'.
And they lack eyes...
