Coordinated call for applications for three (!) thematically related professorships (cell physiology, molecular genetics, and biochemistry) at BTU Cottbus-Senftenberg (Germany) (thread)

Yeah. Just checked. 1.5 hrs between Dresden and Berlin sounds good though.

Does it stop in between Dresden and Berlin? Asking for a friend.

New preprint alert!

We developed an automated framework to optimize tracking pipelines for bacteria, along with a nice integration of tools for bacteria imaging, in the recently released TrackMate 8 (Fiji plugin).

The 40x, NA 1.4 gives a 650x650 Β΅m FoV with FN = 26.5. Not bad

Thanks, Olympus/Evident has some large NA ones with 26.5, but 22 is indeed the common FN.

@healthcare.nikon.com or others: Where can I find information on the field number of Nikon objectives? Seems missing from the objective comparison site? Specifically wondering about the CFI Apochromat TIRF 60XC Oil.

unpopular opinion, the MS Office one is quite okay, although there is a bug on Mac with using the LaTex syntax :) Oh well, one can dream

Have you worked with the equation editor in LibreOffice? PowerPoint supports Latex syntax straight away. And no, I don’t want to insert pictures of my equations.

Tried LibreOffics yesterday: not much compatibility with PowerPoint in terms of the equation editor, unfortunately. Buh.

Introduction - Microscopy Basic Training

I finally got around to writing the discussion section of our lab's basic training course on live cell #microscopy. I explain the tradeoffs involved in designing an imaging experiment and the art of thinking of the experiment as an optimization problem.
