I love these jittery protein models

Another cool example with that more realistic jitter found in the mosh-pit of the cell.

Here's a covid spike in the mosh-pit of the cell (note, I'm finding all these in the feed of Brady Johnston, follow him if you're not already)

Excellent!

Question for those who study flagella: Does motA (bottom part in pink) really spin or does it deform and revert in a way that makes it seem to spin (and cause true rotation of basal body)? I remember hearing people argue about this years ago but I never heard if the debate was

Evolutionary time has length and "width". Gene-sharing traits (sexual reproductive, transformation, transduction...) allow natural selection to work sideways through a population as well as linearly from parent to child.

Someone gifted me this dude. What should we name him?

Kunal probably knows he's exaggerating a bit here but he is onto something: One of the most important differences between humans and other apes has been our ability to focus on crops when they're still just seedlings.

This is why you can't just lean on a tree in Ecuador. Life is everywhere! Yep, those are bats on a log... in the middle of the day. #EvoTour

Why does this female katydid have balls? They're a gift, given to her by her mate. He made them in a gland & stuck them to her after mating. They're a high-protein gelatinous snack for her to munch on while his sperm fertilizes her eggs. Pic by @scibugs on our #EvoTour

Finished :)

Evolution is a huge Bob Ross fan. The whole damn thing is a massive series of happy little accidents.

Mutations of large effect do exist but adaptation in nature usually results from CUMULATIVE rounds of slight variation + selection. Badgers & some dogs have stunted legs (aiding in burrow hunts) but in Dachshunds this is caused by a single mutation that also causes spine issues.

Nick Lane's "The Vital Question" is a gem! Even the bits I don't agree with are a beautiful read.

Because of my YouTube channel, I now get about 15 email offers to "collaborate" or do a "paid product review" every day from people I don't know. Thanks, AI!

Evolutionary time is long, but did you know it also has volume? Population size and recombination rate act as width and height, allowing a dizzying amount of tinkering to happen each generation.
