Imbolc: Blood Moon β€” Kerry C. Γ’ran Ending up in Maryland had been a strange whirlwind. A series of dominos set into motion because one day, in my professor’s office, I had a dream about how to find my children before they were born. ...

Excellent and empoweringe educacioun will nevir be "efficient" yn the waye that a businesse doth stryve to be "efficient." It ys the heighte of knavery to use one standarde to measure everye human activitye. Businesses are ther to make profits. Educacioun ys ther to make the future.

Absolute loser behaviour, imo. If you're outsourcing your job as a researcher to an LLM, please know that all of us are laughing at you.

I would honestly respect that much more.
Without getting too graphic, the experiments involved using guitar strings to make the fingers stretch and curl.
I'll leave it up to you to decide whether that makes your theory more or less likely πŸ™ˆ

I love this. +Regarding what Cora is reposting: what I've noticed when experimenting with AI is that it repels me. I see the result and if I actually needed to dive into the subject I investigate even deeper but don't bother with the AI results. More often than not part of it is made up (I checked)

Obviously the only reason they could imagine for this advantage is men punching each other. And the main reason for men to punch each other, they claimed, is to fight over [insert creepy incel voice] "feeeeemales".

This paper is my goddamn Roman empire and one day I will make a video about it.

I'm being serious, btw. The authors created an "experiment" where they rammed cadaver arms with open hands and closed fists into an impact measuring device and found that fisrs produced a higher impact, thus concluding that being able to make a fist must have been "an evolutionary advantage".

It is also how you find gaps in our current knowledge and questions to investigate.

My entire PhD project was sparked by a really, really bad paper arguing that human hands evolved the way they did in order for men to punch each other better over women.
Literature reviews and spite are my fuel!

We have a really deep test trench on our site that requires very creative contortion to document. I regularly scrape my hands on pieces of 120'000 year old animal bones sticking out of the profile when I pull my camera back up.

So, if you are an @archaeologyeaa.bsky.social (EAA) member from 2025-2026, you received yesterday your email for the per-rollam vote of the past Special Meeting and the documentation attached to it… if you still doubt what to vote, please read all the documents. My short digest:

Opinion | I'm a Minneapolis sociologist who studies violence. Here's how ICE observers are helping. Research into how violence occurs shows that disapproval from the people around you can help reduce it.

For @msnownews.bsky.social, I wrote an article about how ICE Watch is grounded in sociological theories of violence prevention.

The reality is that most men will only commit public violence in extremely specific scenarios and ICE Watch disrupts the conditions necessary for escalation.

The very big rocket that will be taking four humans on a journey that will be the furthest any humans have journeyed from everything on Earth in 54 years - incl. every living being that we know about, will be rolling out in ~12 hours from now.

It's slow TV.

But with a big rocket. πŸš€

Read our new paper in Genome Biology & Evolution to learn more about how sequencing the genome from a 14,000 year old wolf puppy's last meal yielded novel insights into the woolly rhino's extinction:

It's been a pretty bad one, for sure! I am also 5 weeks out of surgery, so the timing really is impeccable ✨️

The past five weeks of recovery have mostly been the repeated harsh realization that what I had considered rest is actually still me pushing myself.

I can't talk specifics yet but I just had my first ever peer reviewed paper accepted by a very prestigious journal in my subfield and it's a first author paper, too.
This should feel like a big deal but in light of *vaguely gesturing at everything*, I will put it down as a #TinyJoy.

I've been in bed with the flu all week and can honestly say that the fever dreams were less upsetting than looking at the news.

One of the last woolly rhinos to walk Earth was eaten by a wolf pup β€” and scientists have now sequenced its genome from the undigested meat More than 14,000 years ago, a wolf pup ate a piece of woolly rhino. Scientists have analyzed the rhino's DNA to figure out why it went extinct.

Scientists managed to extract a high-coverage genome of an extinct woolly rhino from an undigested piece of its flesh found in the stomach of a permafrost-preserved 14kyo wolf pup. πŸ§ͺ🏺
