Wheeled toys were all the rage in the ancient world. Here are four lovely examples: a Greek horse, a Mesopotamian ram, an Iranian hedgehog & a Mesoamerican jaguar. The jaguar one is particularly cool because it shows that Mesoamericans knew about wheels; they just didn't use them for transport.

I can talk for hours about BTS and especially about my dream of clinical BTS. If this sounds interesting, feel free to invite me to your department. No funding required, just cookies and (virtual) warm hugs. #BigTeamScience

the internet has decided that em-dashes are a hallmark of llm writing, which is *extremely* annoying to me, as someone who uses em-dashes all the time.
dear internet please consider the possibility that LLMs use em-dashes a lot because they're, like, good

Power analyses are all fine and dandy until your power analysis comes back with you needing N = 34 people to have 90% power, you run the study with N = 34, get the effect, and no one believes your study because your sample size is so small.

Can reading one article change your belief in free will? New studies say maybe—but the effect doesn’t last. Our beliefs might be more resilient than they seem

Rob Chavez gives the helpful/correct answer below, but here's another thought:
Your preprint gets to be your director's cut. Put that baby on OSF or Zenodo and add a link in your figure caption.

International research collaborations run into international problems: Embargoes, authorship conflicts, ethical use agreements. This should not be the way.
We propose a framework, a memorandum of understanding between countries, to allow free collaboration between researchers
