Everything Is Heritable:
-
“Accurate Genomic Prediction Of Human Height”, et al 2017
A vindication of Steve Hsu’s predictions: the GWAS lasso works! (2014/et al 2014 /2015) The height polygenic score has doubled and now explains the full SNP heritability.
This has many implications: primarily, polygenic scores are going to start doubling or quadrupling regularly as contemporary datasets (UKBB in particular?) start hitting the threshold. Years of incremental improvements in GWAS will be compressed into single papers. It will be exciting to have polygenic scores for intelligence which explain up to 30% of variance! These IQ PGSes will highly likely be available by 2019, and it’s possible that they could be computed this year in 2017 (depending on whether existing datasets are big enough to push past the threshold, perhaps assisted by genetic correlation techniques like MTAG). Plus, of course, more accurate genetic correlations. Aside from being one last bullet in the head of genetics denialism, it will massively increase the value of embryo selection and genome synthesis. Has it really been only 4 years since et al 2013 was published? It feels like so much longer… It’s worth noting that the cumulative number of genomes is substantially larger than the annual output, and the former is what counts; for example, under one set of assumptions with a fixed annual investment and the observed exponential decrease in cost, there will be 5x total genomes than annually produced, so since 23andMe/Ancestry.com are reportedly collecting approaching millions of samples per year… (In a since deleted post: “AncestryDNA alone attracted 1.4 million customers in the fourth quarter of 2016, with an additional two million in the first half of 2017…”) The genome sequencing exponentials have been quite a tiger to ride. Very Kurzweilian: everything important happens near the end.

“GWAS meta-analysis (n = 279,930) identifies new genes and functional links to intelligence”, et al 2017 (predicts 5.4% variance)
-
“GWAS Meta-Analysis of Neuroticism (n = 449,484) Identifies Novel Genetic Loci and Pathways”, et al 2017 (4.2% of variance; would be particularly interesting target for embryo selection given the extreme genetic correlation with happiness of rg = -0.68)
-
“Genetic analysis of over one million people identifies 535 novel loci for blood pressure”, et al 2017
-
“Genome-wide association study identifies 112 new loci for body mass index in the Japanese population”, et al 2017 (Speaking of rapidly increasing sample sizes: Japan’s BBJ from 200816ya is starting to come online with n = 200k, and the BMI results show good genetic correlation with UKBB, so pooling will be useful.)
-
“Hidden heritability due to heterogeneity across seven populations”, et al 2017 (the curse of racial genetic differences for GWASes: “Missing heritability” isn’t, but naive GCTA/GWAS estimates are biased downward by heterogeneity in measurements)
-
“Genetic Diversity Turns a New PAGE in Our Understanding of Complex Traits”, et al 2017; “Multiethnic Meta-analysis Identifies New Loci for Pulmonary Function”, et al 2017 (The blessing of racial genetic differences for sophisticated GCTA/GWASes: many differences in gene frequencies, linkage disequilibrium patterns, environments, enabling more powerful GWASes. Don’t fear the population structure, benefit from it!)

-
“Quantification of frequency-dependent genetic architectures and action of negative selection in 25 UK Biobank traits”, et al 2017 (mutation load & purifying/negative selection within 25 UKBB traits: larger effects of rarer variants, but rare variants continue to disappoint by not accounting for much variance in total.

AI
-
“Revisiting Unreasonable Effectiveness of Data in Deep Learning Era”, et al 2017 ( blog; good to know more data keeps helping, but it will be a long time before anyone, even Google, truly needs corpuses of 300M+ images—although ‘a long time’ apparently turned out ot be only ~3 years and scaling papers keep coming out)

-
“On the Reproducibility of Psychological Science”, et al 2016
-
“Disappointing findings on Conditional Cash Transfers as a tool to break the poverty cycle in the United States” (The null is expected since their previous RCT failed (their p-hacking and selective focus notwithstanding), but it’s particularly troubling to see results inflated by self-reported data; as the US is not Scandinavia, many studies depend on self-report.)

-
“An Autopsy of Cooperation: Diamond Dealers and the Limits of Trust-Based Exchange”, 2017 (The India example is striking. So the Indian government decides to subsidize exports (in the hopes of helping the poor by spurring economic development) by forcing companies to make subsidized loans; this winds up primarily benefiting the… diamond cutting industry, subsidizing sales to rich foreigners. Well done, statists. I am probably being insufficiently cynical about Indian politics by assuming this is unintentional and due to anti-market prejudices & ignorance rather than deliberate due to the usefulness of diamonds for bribery, smuggling, & corruption.)

Fiction
Film/TV
Live-Action
-
Modern Times, Charlie Chaplin (much longer than The Gold Rush; like The Gold Rush, it suffers from the transition to comedy & satire to serious drama, in this case, about the Great Depression. The opening factory sequence is great, as is the Little Tramp’s singing performance in the cafe, but everything in between is a slog.)
-
The Gold Rush (192599ya/194282ya), Charlie Chaplin (holds up better than I expected but still probably not recommended. Comedic timing has changed as a number of scenes I thought should have gone on longer and elaborated more on their theme were too curtailed, and the attempt at introducing halfway in a dramatic arc/love story falls flat as overly sentimental & pompous—the movie should stick to its knitting, the comedy. The best scene by far is the “dance of the bread rolls”.)
Animated
-
Zootopia (Excellently executed, but the worldbuilding is more baffling the longer you think on it so probably better not to—the only things that would make it make sense would also turn it into a 1984-esque dystopia where the ending and The Moral of the Story is akin Winston Smith realizing “I love Big Brother”.)
-
K-On! Movie 201113ya (beautifully animated but hopelessly bland despite a sweet ending; I suppose that’s an apt description of the entire K-On! franchise but I was hoping that the movie could do more.)
