Scary pseudopodia
Exciting announcement! My new department is launching a postdoc fellowship in quantitative biology. Fellows will be co-advised by two Bio faculty, one that is quant focused (not me) and one that is not (me???). I would love to co-sponsor a postdoc and build a collaboration so please reach out!
Can you share the link?? Thanks!

I also make a smartphone analogy in doi.org/10.1016/j.ti...! But I argue against technological developments as valid analogies for understanding energy demands in cell evolution. (A reason is that part density increases in smartphones due to miniaturization, but cell mass density remains constant.)
How did eukaryotic cells with complex architecture evolve from simpler prokaryotic cells? DNA analyses offer possible answers

Interesting. Need to read this in detail...

Is it trying to make hyphae? :P
Congrats, Will!
What are you listening to?
What an out-of-this-world view!
Lovely!
What is the most profitable industry in the world, this side of the law? Not oil, not IT, not pharma.
It's *scientific publishing*.
We call this the Drain of Scientific Publishing.

In late April, we welcomed a brand-new American Red Wolf pup to the pack! With less than 30 individuals left in the wild, this little girl is a crucial part of her species' conservation success. Luckily, she's doing well and has recently found her voice 🐺🎶🌍
As national medical, scientific, public health and patient organizations, we call for the resignation of HHS Secretary Robert F. Kennedy Jr. to ensure the health of the American people. Read our statement: asm.org/press-releas...
I gave a symposium talk at the European Society for Evolutionary Biology 2025 (#eseb2025) meeting last week and this was my title slide showcasing how I was speaking as an independent scientist because @dalhousieu.bsky.social @dalhousie.bsky.social has locked us out.
It looks like current policies will result in a much lower number of ESI R35 MIRAs this year which immensely support early career researchers.
Cars are always first
Congratulations, @messorensen.bsky.social!
Such a great week full of symbiosis science, good food, and great company with @mixotrophe.bsky.social visiting the ECSO Lab (ecsolab.com)!

What causes the pink color? Halophilic archaea or purple bacteria??
So excited to listen to this tomorrow!
Teach me
Bacterial ICMs exhibit internal invaginations that resemble eukaryotic cristae. (A)TEM images showing tubular cristae-like ICM compartments in free-living Desulfobacterota, and similar cristae-like ICM tubules in Desulfovibrio carbinolicus strains. The eukaryotic model organism S. cerevisiae exhibits tubular cristae structures, whereas the commonly used HEK293 cell line exhibits predominantly lamellar cristae structures. Scale bars: 500 nm. (B) Eukaryotic mitochondria tend to exhibit lamellar, tubular or discoidal cristae morphology, whereas orders of the class alphaproteobacteria exhibit a range of ICM morphologies. Lamellar-like ICMs, which exhibit parallel cytoplasmic protrusions that do not contact the inner membrane, are commonly observed in nitrogen-fixing and several methanotrophic alphaproteobacteria. (C) This simplified and non-exhaustive cladogram indicates the two domains of life – bacteria and archaea – with proto-mitochondria emerging in early alphaproteobacteria. Eukaryogenesis is marked by the horizontal transfer (red dotted arrow) from Bacteria to Hordarchaeales in Asgard archaea. §, †, #, * and ‡ connect species listed in B to their respective clades in C.
Kailash Venkatraman, Nicolas-Frédéric Lipp & @ibudin.bsky.social examine the similarities between prokaryotic intracytoplasmic membranes & mitochondrial IMs, & discuss whether cristae evolution has driven specialisation of the #mito lipidome.
