excessive cell 'skin' isn't a norm, but there's a twist: it's a *necessity*! The more folds a big cell's membrane has, the better for its surface-to-volume ratio: www.cell.com/current-biol... (in mammals, at least)
Plasma membrane folding enables constant surface area-to-volume ratio in growing mammalian cells
Cell surface area-to-volume ratio (SA/V) can limit cell functions. SA/V is believed
to decrease as cells grow larger, but a new study by Wu et al. shows that mammalian
cells maintain near-constant SA/...

Gerbils don't excel at any particular manoeuvre, but gerbils with long shins tend to be better jumpers while gerbils with long thighs are more manoeuvrable. They don't prioritise one manoeuvre at the expense of another 1/2🧵 @brown-ibes.bsky.social

Sea anemones track the suns position?! 🤯 So thrilled to share our paper is finally published in @J_Exp_Biol! 🎉
Congrats to my student leads Eliska Lintnerova and Callum Shawn.

The world is full of crazy and sad news, but here is a protein that localizes to only one of the two flagella

Осьминоги зиганули (sorry don't know how to properly translate this russian meme phrase into English). Now thanks to this report in Current Biology www.cell.com/current-biol... we know that cephalopods have Z sex chromosomes, and the females have Z0 genotype, while males have ZZ genotype.
Cephalopod sex determination and its ancient evolutionary origin
Coffing et al. assemble a chromosome-level octopus genome assembly, revealing that
the female octopus has just one sex chromosome (ZO karyotype), and males have two
(ZZ karyotype). They conduct genomi...

While Simon Baron-Cohen argues that no other species except Homo sapiens is able to invent anything (see his 'Pattern Seekers' book), Goffin's cockatoos successfully invent soaking rusk in water before eating it.

What interests me here is that our simple textbook 'diffuse' Hydra nervous system in fact has distinct neuronal (sub)populations doing different things. Surprisingly, the idea that the microbiota influences host's neuronal activity via glutamate and the like (1/2)

Control of behavior is a complex interplay between neurons and environment, such as
the microbiota. Giez et al. show that this complex interplay is already evident in
one of the simplest nervous syst...

Guess here I will collect links to scientific papers that interest me, and they would mostly be bizarre/rodent-related/plant-related/lgbtq-related. God please give me time and strength to at least minimally cover those publications that I like the most.
