Who Were We and Who Will We Become? Hi and Welcome! This is the third issue of Palimpsest of Flesh. As I've gotten really into the research (and grant requests!) for my next book, Warriors, Wanderers, and Weavers: The Real Story of Our ...

For my next book, I've been thinking abt how I can relate to people who lived 5,000 or 10,000 years ago. What do we have in common? What's incomparable? This month's newsletter essay explores one part of that idea. + pop-culture faves from pods to film! palimpsest-of-flesh.ghost.io/who-were-we-...

Which Sex Is Stronger? | The Open Mind, Hosted by Alexander Heffner "The Stronger Sex" author Starre Vartan discusses the latest research on women's mental and physical capacities.

Appearing on The Open Mind on @pbs.org to discuss my book was a huge honor! Host Alexander Heffner asked me about The Stronger Sex - but we also got into a bit of a political convo too, which was interesting. See the whole thing here (politics last 10 mins). www.thirteen.org/openmind/sci...

Meet three scientists who said no to Epstein The warning signs included a web search, a mother’s doubts, and inklings of a β€œsexist attitude”

WOW. Great piece in @science.org about three researchers courted by Epstein who said "no thanks." Two of the three were warned off by the women in their lives which is a fascinating bit of anecdata. Incredible details in the piece. www.science.org/content/arti...

Woman sues Kenbridge, police after chief allegedly tipped off shooting suspect The town of Kenbridge and its police department are facing a lawsuit of more than $140 million.

A woman’s ex boyfriend, who is a cop, threatens to shoot her

Women are at the highest risk for being killed when they try to leave a relationship.

She calls 911 for help & the Police Chief WARNS the boyfriend instead.

Boyfriend opened fire on her car

We aren’t angry enough.

The issue here is obviously effed but I'm here to think aloud, yet again, how incredibly WEIRD it is that men basically wear identical uniforms as each other (in many aspects of professional life) and women just...don't. I think this says so, so much about gender roles and I find it fascinating.

Reading people. Body language. Knowing how to connect with people totally unlike you and with different backgrounds and beliefs. Defusing tense situations. Gaining trust. High endurance, pain tolerance, and work ethic. Reaction time. Prioritizing order of execution. Anticipating people’s needs. Tons

Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects'. Here we present results from a 2023 field experiment on Elon Musk's platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects.
Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users' feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X's algorithm has persistent effects on users' current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship.

A new paper shows that less than 2 months of exposure to Twitter’s algorithmic feed significantly shifts people’s political views to the right.

Moving from chronological feed to the algorithmic feed also increases engagement.

This is one of the most concerning papers I’ve read in awhile.

"Gender studies...brought a critical lens to the biological determinism Trump invokes. And this critical lens extends to revealing how gender hierarchies enable the kind of abuses that some men in Epstein’s circle seemingly believed they had the right to commit."

Organic molecules found in a 500-million-year-old fossil, upending the science of paleontology Scientists have found traces of a tough material that once formed the outer shells of ancient sea creatures called trilobites, preserved inside fossils that are more than 500 million years old. The discovery shows that parts of living organisms can last far longer in rock than experts once believed, and it changes how scientists think about how carbon is stored deep inside the Earth over long periods of time. Finding chitin in a fossil Inside layers of shale rock near Death Valley in eastern California, researchers found a trilobite fossil from the species Olenellus, an extinct marine animal that lived on the ocean floor more than 500 million years ago, that still contained a small piece of its original shell. Lab work at the University of Texas at San Antonio (UTSA) pulled a clear chemical signal from that shell patch. Elizabeth Bailey, an Earth and planetary scientist at UTSA, linked that signal to a shell polymer that older searches missed. Even with just a few fossils, discovering chitin hints that some carbon-rich compounds can stay trapped under ordinary burial conditions. Modern crab shells and insect skins rely on chitin, a tough sugar-based material in many outer coverings, to stay stiff...

The takeaway here is not that reporters are no longer interested in reporting on climate. It’s that reporters have fewer opportunities to do so, many climate reporting jobs have been axed, and good outlets have folded or shrunk. Some people are still doing good work, yes, but the trend line is down
