Genetics:

Everything Is Heritable:
-
“Common risk variants identified in autism spectrum disorder”, et al 2017 (ASD, as expected, crosses the sample size threshold for hits. More importantly: the genetic correlations imply that autism is not a single thing & that intelligence genes are not inherently ‘autistic’; hence it will be possible to select for intelligence without selecting for autism. I’ve always had a hard time believing the simple genetic correlations between intelligence and ‘autism spectrum disorder’ since it’s unclear why variants that improve intelligence would decrease social functioning which should require intelligence as much as anything else; if it’s simply that there’s heterogeneity and that, say, ‘systematizing’ is shared between intelligence and autism diagnoses, that would be a credible resolution.)
-
The genomic revolution will continue until morale improves: “Between Black Friday and Cyber Monday, leading personal genomics company AncestryDNA sold about 1.5 million of their testing kits designed to provide insights into your ethnicity and familial connections.”
-
“Human longevity: 25 genetic loci associated in 389,166 UK Biobank participants”, et al 2017 (Tripling the sample size yields more hits, as expected.)
-
“Predictive accuracy of combined genetic and environmental risk scores”, et al 2017
-
“Most people say they think nurture is more important than nature, especially white Americans”
-
-
Engineering:
-
“A 100-Year Review: Methods and impacts of genetic selection in dairy cattle—From daughter-dam comparisons to deep learning algorithms”, et al 2017 (A preview of improving genomic prediction & selection.)
-
“Haemophilia A genetic-engineering trial results ‘mind-blowing’” (on et al 2017 )
-
“Crispr Therapeutics Plans Its First Clinical Trial for Genetic Disease”
-
-
Recent Evolution:
“A simple test identifies selection on complex traits in breeding and experimentally-evolved populations”, et al 2017 (Potentially big: an easy, powerful test for recent evolution/selection. Authors claim this withstands high polygenicity in soft sweeps well, and if anything, gains statistical power in those scenarios. Could this uncloak much of the rest of recent human evolution? We know it’s there across all sorts of traits, we just can’t identify the specifics yet…)
AI:
-
“Mastering Chess and Shogi by Self-Play with a General Reinforcement Learning Algorithm”, et al 2017 ( commentary; meme summary; expert iteration generalizes even better than I expected it to, in chess reaching parity with or superiority over Stockfish (!) in 4 hours wallclock.)
-
reproducibility/evaluation/progress issues: “Deep Reinforcement Learning that Matters”, et al 2017/ “Are GANs Created Equal? A Large-Scale Study”, et al 2017/ “On the State-of-the-Art of Evaluation in Neural Language Models”, et al 2017
-
“Machine Learning for Systems and Systems for Machine Learning”, Jeff Dean, 2017 NIPS slides (see also the mentioned “The Case for Learned Index Structures”, et al 2017 which surprisingly proves that small NNs are profitable inside databases; aside from revealing some details on the enormous neural processing power of the second generation of TPUs—each pod of 64 TPU2s will deliver 11,500 teraflops, compared to, say, a 1080944yati’s ~13 teraflops—Dean reveals the incredibly ambitious plans to use reinforcement learning & neural nets for pretty much everything in Google’s databases, compilers, OSes, networking, datacenters, computer chips… Truly, all tool AIs want to be agent AIs.)
-
“High-Resolution Image Synthesis and Semantic Manipulation with Conditional GANs”, et al 2017 (

)
Politics/religion:
-
“Book Review: David Friedman’s Legal Systems Very Different From Ours”
-
“Post-apocalyptic life in American health care”; SMBC on health insurance; “Prescription Drugs May Cost More With Insurance Than Without It”. (How far can it go? What is the breaking point? “There is a great deal of ruin in a nation”, per Smith—but not an infinite amount.)
-
“In China, a Three-Digit Score Could Dictate Your Place in Society” (a more in-depth look into the ‘social credit’ system than I’ve seen before)
-
“Postmortem: Every Frame a Painting” (Copyright is why we can’t have nice things: they spent almost as much time dealing with YouTube’s copyright enforcement as editing, it sounds like, and had to give up entirely on major topics like Andrei Tarkovsky because they didn’t think they could trick the IP enforcers into permitting a legitimate exercise of fair use.)
Psychology/biology:
-
“The Fireplace Delusion”; “Wood-smoke Health Effects: A Review”, Naeher et al 200717ya (the Global Burden of Disease estimate for poor countries is that 7.7% of all DALYs lost is due to chronic & ‘lower respiratory infections’, more than either HIV or malaria. Happy holidays.)
-
“The Social Origins of Inventors”, et al 2017 (Since they include no correction for measurement error and the IQ score is quite bad (decimalized!) and patents aren’t so great either, some of their interpretations, particularly the last one, are highly questionable, but the takeaway is that even crude measures of intelligence and innovation show a strong predictive relationship, as expected.)
-
“IQ decline and Piaget: Does the rot start at the top?”, James 2017 (James Flynn (of the Flynn effect) endorses dysgenics and explores where the impacts are: in the most intelligent childrens’ ability to abstract and experiment. This is further evidence that the Flynn effect is hollow as by thin tails, a half SD or more average increase should produce an enormous multiplicative increase in the number of children at the highest stage of Piagetian development, rather than an equally enormous fall.)
-
“Meta-Analysis of the Antidepressant Effects of Acute Sleep Deprivation”, et al 2017 ( wake therapy is so weird)
-
“Do High School Sports Build or Reveal Character?”, 2018 (everything is correlated/correlation ≠ causation/CICO is false)
-
“As Zika Babies Become Toddlers, Some Can’t See, Walk or Talk” (Zika is turning out to be as bad as the initial microcephaly & birth defects indicated.)
-
“China’s Selfie Obsession: Meitu’s apps are changing what it means to be beautiful in the most populous country on earth” (on mobile apps & streaming)
-
“How (and Why) Athletes Go Broke” (head injuries…?)
-
“Does pride really come before a fall? Longitudinal analysis of older English adults”, et al 2017
Technology:
-
“How a Dorm Room Minecraft Scam Brought Down the Internet” (So Mirai was developed to… extort Minecraft servers‽ 2017 is truly beyond parody. Also, we’re doomed.)
-
“Computer latency: 1977–402017” (Why are modern computers so much less pleasant than a 1980s terminal in some ways? One way is that they are actually slower in a crucial way: input/display latency. Luu measures terminal scrolling in a wide variety of devices and scroll latency in mobile browsers and finds decades-old devices are often the best. Even keyboards turn out to vary by a factor of 5 in simple keypress latency!)
Economics:
-
“99 2017 Was A Great Year: If you’re feeling despair about the fate of humanity in the 21st century, you might want to reconsider.” (2017: between the steady improvements across the board on almost all metrics of health and wealth and tech and violence, and population growth, 2017 saw perhaps the greatest increase in utility in the history of the human species—just like 2016 before it, and 2015, and 2014…)

Hacking Minecraft economies with arbitrage & cartels (Alice Maz)
Books
Fiction:
Film/TV
Live-action:
Animated:
-
Prison School (inside all the juvenile raunch, the BDSM and nipple-hair jokes, in the broad manzai-style comedy familiar from anime comedies like Cromartie High, beats a full-metal shonen heart of gold as the protagonists become nakama and learn the value of manly friendship. Combined with the fairly intricate plotting, I enjoyed PS more than I expected.)
