🚨 New paper! 🚨
🐒 White-faced capuchins experience high rates of infanticide.
🐒 Infanticide is costly to female reproduction.
🐒 Do females exhibit the Bruce effect (termination of pregnancy) to reduce these costs?
🐒 Spoiler: Nope!

I wanted to get a video of this ghost crab but every time I got close to their hole they scuttled back in, so I tried getting clever with it. I made a little sandcastle and shoved my phone into it, hit record, and walked away. Crab was VERY suspicious of this addition to their environment.

Rather than seeing this as a political project, I would suggest it's better to see this as a reflection of an economy increasingly centered around the extremely niche emotional needs of people with billions of dollars to spare...

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN.
It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package.
Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

the Dems spent all of biden’s presidency triangulating on immigration and look where it got them.
but if you write for the Atlantic you can just write the same “dems need to triangulate” article every week, no problem!

The biggest problem American liberalism faces is how to maintain high levels of immigration while respecting the democratic will of the public. I have an idea.

Liberals don’t have to lose on immigration
“Moderating” on immigration doesn't mean abandoning it

woah this is genuinely, utterly WILD
Ant queens of one species produce males of another species, so she can then mate with them and produce hybrid workers!
This is so gloriously weird I can't quite compute it 🤯🧪🐜

‘Almost unimaginable’: these ants are different species but share a mother
Ant queens of one species clone ants of another to create hybrid workers that do their bidding.

As end-of-empire scenarios go it is so much more dignified to get your capital city sacked by the Visigoths than to have a bunch of illiterate rich people in their 70s doing it through a series of incomprehensible tantrums because their brains were defeated by their phones.
