Jun. 20th, 2026 04:44 pmDept, all more complicated: Did the iPhone Cause the Baby Bust?
Despite the overconfident claims of many a podcast bro, big shifts in population trends like birth rates (or life expectancy) usually defy simple explanation. For example we still don’t really know what caused the Baby Boom, which was a big deviation from previous trends towards lower birth rates in the US and around the world.
(I should have noted where else I saw 'the 1950s were a weird blip' somewhere this week!)
Why the Human Genome’s Tangled Physicality May Confound AI
Our genetic heritage is not a blueprint or an algorithm, as many biologists have imagined, but something else entirely.

Dept, surely this is the premise for a dystopian novel: Men Can Lose Their Y Chromosome With Age, And We Finally Know The Cost:
The human Y chromosome is shrinking.
In the next 5 million years or so, some geneticists think the sex-determining chromosome will vanish completely from our species.
In the meantime, we have a bigger concern at hand.
As some men age, they are losing the Y chromosome in their blood, brain, or immune cells, and that could have serious health effects.
A loss of the Y chromosome has surprising connections to cancer, kidney disease, heart disease, and Alzheimer's.
For decades, researchers have noticed that as some men grow older, certain cells in their bodies begin to lose their Y chromosome.
This ties right in with the kind of arguments being made by Geddes and Thomson in The Evolution of Sex (1889), which, while it didn't quite say that the human male sex was like the salmon, doomed to swim upstream to spawn and die, did not quite eschew that analogy when contrasting the katabolic male with the anabolic female.

Sleepmaxxing for the early modern insomniac: Sniff Your Way to a Good Night’s Sleep:
We discovered hundreds of recipes for sleeping well within handwritten books of medical care, which show how hard people worked to try and maintain healthy sleep. These treasure troves of household medical knowledge were often compiled, expanded and edited by multiple generations of a single family. They indicate that sixteenth and seventeenth century English households were engaged in pioneering medical experiments relating to sleep on an unprecedented scale. Women and men from many different walks of life went to great lengths to design, test, and adjust recipes that could cause sleep, that could extend or shorten its duration, that could prevent nightmares, or that alleviated joint pain, headaches, and a host of other bodily ailments that regularly interrupted a peaceful night’s sleep.
