Our paper is out! Enamel nanocrystal misorientation increased with meat-eating and agriculture Misorientation scales with dietary hardness. And in the human lineage it increased with the introduction of meat and agriculture, but not with the Industrial Revolution. www.nature.com/articles/s41...

Enamel nanocrystal misorientation increased with meat-eating and agriculture - Nature
An analysis of enamel nanocrystal misorientation in primate and human teeth across three major dietary shifts in human evolution shows that misorientation increased with harder diets, suggesting that ...

Nanostructure of tooth enamel casts light on dietary shifts as humans evolved
The arrangement of mineral nanocrystals in the tooth enamel of primates, hominins and modern humans altered as the diet of these species changed.

I finally remembered that noise cancelling headphones and white noise exist. My focus exists again.

So, once again, it turns out that giving poor people money helps them to become not/less poor. But I repeat myself. Again.

Lost in the conversation about the "merits" of "talented" men creeping on young women is how whatever contributions they have made to the medium is completely drowned by all the contributions their creeping has impeded. Women creeped on by their mentors/idols often just quit their dreams, betrayed.

It's been a sad year for foundational ape researchers - very sorry to hear about the death of Frans de Waal. Chimpanzee Politics was pretty mind-blowing to baby primatologist Erin.

Emory primatologist Frans de Waal remembered for bringing apes ‘a little closer to humans’
Beginning with his groundbreaking 1982 book “Chimpanzee Politics,” Frans de Waal pioneered studies of primate cognition and shattered long-held ideas about what it means to be an animal — and a human.

sad news - Duke University decided to dump their herbarium, which has over 800,000 plant specimens, one of the largest among in America, and includes many type specimens of Lady Gaga ferns. What a shame. Please stop Duke admins for making this horrible mistake!!

My unassisted, unmedicated birth + baby care cost $28,336.25. Luckily, I have fantastic insurance, but this is a good reminder that many people do not. A natural, physiological event should not require people to save and pay off for years due to mediocre insurance.

So the next time I’m “feeling swamped” I’ll just say I’m “immersed in nature” and it will all be OK. Right?

Too much time reviewing papers is taken up by explaining statistics to authors. I'm by no means a statistical expert, but this is getting tedious.

I thought I had a decent understanding of nutrition and macros Gestations diabetes has proved me wrong I ate a kale salad and 2 gulab jamun (fried dough in sugar syrup) for lunch and somehow my blood sugar is under 90 But when I ate a protein-heavy no-sugar snack and it was >150 I got nothing
