Broader #bioimaging and #microsky people - anyone have any suggestions for sources of ~0.25mm non-cytotoxic double sided adhesive sheets?
Alternatively, a DIY solution might be possible. If anyone has any ideas on a suitable non-toxic double-sided adhesive sheet material, then purchasing those and using either consumer grade die-cutter or online-die cutting services could be a straightforward solution.

Has anyone had this problem? A hydrophobic water objective? The objective is great but we struggle to keep the water on the lens...
-> Maybe a solution is to paint a circle around the nose with a 'hydrophobic barrier pap pen" (link below). Has anyone tried this?

Ever wondered if analyzing your images by using intensity Z-projections impacts your data?
Happy to announce my guest article in Microscopy & Analysis on that topic. It's a very short read but worth for everyone dealing with image analysis!

One of the most useful resources for anyone who uses fluorescence methods.
The FPbase spectra viewer just had it's biggest software refactor in 6 years. It *should* be largely invisible to the end user (hopefully just faster and less buggy). Please let me know if you find any issues as you use it!

Another aspect to consider is how much colors are saturated, depending on the LUT, the screen type and settings it can make a huge difference on data readability. Green Fire Blue is popular but really saturated

Does anyone know a database where let say I have 2 proteins: Integrin and FAK, I can find out what motif/sequence of amino acids mediate their interaction? Thank you.
