Yep, it lags a little. But still quite impressive considering that each "pixel" is a 150 MPixel multires image. Overall the total number of 'adressable' pixels in this 2D image are 225x225x150 Mpix = 7.6 Tera pixels.

New preprint from my PhD in
@amphispacelab.bsky.social
is out! π₯³ We investigated the evolution of my favorite gene FoxQ2 across 21 animal phyla, and found three ancient paralogs with a very dynamic history. More on phylogeny, synteny, and comparative in situs in the π§΅ below!

Evolutionary dynamics of FoxQ2 transcription factors across metazoans: A tale of three ancient paralogs
FoxQ2 is a highly conserved class of Forkhead-box transcription factors expressed on the anterior side of the body in cnidarians and bilaterians. Despite this conserved expression pattern, recent phyl...
