A lone battle: Why is Pedro Sánchez the only European leader to take on Trump? As the Spanish PM decries the war in Iran, other politicians are unable – or unwilling – to speak against the US president

Because the other European leaders are invertebrates.

"Air raids are not only wrong. They are loathsome and disgusting. If you had ever seen a child smashed by a bomb into something like a mixture of dirty rags and cat’s meat you would realize this fact as intensely as I do." - J.B.S. Haldane, 1938.

Weaponizing Kinship: Four out of ten Colombians have lost a family member in the conflict 🇨🇴
Enrique Acosta, Diego Alburez, Maria Gargiulo, & Catalina Torres quantified how many Colombians have ever lost at least a family member to conflict-related violence.

How does social influence shape collective outcomes? When does it lead to lock-in on inferior options?

‘No to war’: Sánchez doubles down after Trump threat to cut off trade with Spain PM says his country will not be complicit in growing conflict in Middle East ‘simply out of fear of reprisals from someone’

Finally an European leader with a spinal column and, yes, balls (or ovaries, or whatever).

I have lost all hope. Especially if it is supposed to come *from the UK*.

Many organisms, including humans, reshape their environments in ways that influence the conditions faced by future generations. We ask whether this can favour biological variation with @irisprigent.bsky.social in our new paper. Thanks to @dee-unil.bsky.social @snsf.ch

I guess all of this is the fault of the Norwegian Nobel Committee, Gianni Infantino, and María Corina Machado.

Wasn't this essentially the argument of The Matrix?

That is messed up.

My Greek teacher complains about the Spanish subjunctive, I complain about Greek declensions, and about Greek verbs having two aspects.

EXCLUSIVE: Harvard placed Martin Nowak on paid administrative leave amid a renewed investigation into his ties to convicted sex offender Jeffrey Epstein, according to a letter obtained by The Crimson.

“Biomedical and life science articles by female researchers spend longer under review”

Definitely resonates...

If we are making lists of non-ignorable "complexity" in biology, how about the interaction of selection and development? Many biologists find it boring (unnecessary complexity) or threatening (old naive adaptationism called into question). @mauriciogforero.bsky.social does good work in this area!

This mathematical treatment both simplifies and extends our previous simulation treatment of the subject: www.cambridge.org/core/journal...

Great to see Germany's largest research society support research assessment reform: less garbage bibliometrics like impact factor and h-index, less emphasis on over-production of papers no one wants to read, more expert assessment of quality and rewards for teamwork.

Skate of the Onion.

The Epstein files document what many women researchers have long experienced but rarely seen laid bare so starkly: exclusion operating behind closed doors, shaping who gets funded, invited, mentored, and taken seriously. How many of these networks, norms, and gatekeepers remain in place?

Today, my mom asked me if I ever considered publishing in Science Magazine to reach a broader audience... Thanks, Mom. #oceanography 🌊🤦‍♀️🙄

Thanks, Sam. I am reassured.

Graphs are maximally expressive for higher-order interactions We demonstrate that graph-based models are fully capable of representing higher-order interactions, and have a long history of being used for precisely this purpose. This stands in contrast to a commo...

We clarify central misconceptions in the recent literature on "higher-order networks".

“Humans across multiple languages spontaneously associate the nonwords kiki & bouba with spiky & round shapes, respectively...We tested the bouba-kiki effect in baby chickens. Similar to humans, they spontaneously chose a spiky shape when hearing a kiki sound & a round shape when hearing a bouba.”😲🧪

The market for marriage - Works in Progress Magazine It is a truth universally acknowledged, that a single man in possession of a good agricultural surplus, must be in want of a wife.

Humans exhibit an astonishing variety of marriage systems. Sometimes monogamous, other times polygamous, occasionally we even marry ghosts. The diversity can seem to defy any general explanation. In my new piece for Works in Progress, I write about the Darwinian logic behind it. 1/

President Milei tweets a slogan that he meant to be a play on words meaning "Milei doesnt support the [General] Strike"

But written in a way that literally means;

"Milei cannot get an erection"

Help. I cant breathe 😅
