The grandmaster diet: How to lose weight while barely moving
> Robert Sapolsky, who studies stress in primates at Stanford University, says a chess player can burn up to 6,000 calories a day while playing in a tournament, three times what an average person consumes in a day. Based on breathing rates (which triple during competition), blood pressure (which elevates) and muscle contractions before, during and after major tournaments, Sapolsky suggests that grandmasters’ stress responses to chess are on par with what elite athletes experience.
Sinister right-handedness provides Canadian-born Major League Baseball players with an offensive advantage: A further test of the hockey influence on batting hypothesis
> Recent research has shown Major League Baseball (MLB) players that bat left-handed and throw right-handed, otherwise known as sinister right-handers, are more likely to have a career batting average (BA) of .299 or higher compared to players with other combinations of batting and throwing handedness.
> Since the inception of the MLB, the relative proportion of Canadian-born sinister right-handers is at least two times greater than players from other regions, although being Canadian-born does not provide a direct offensive advantage. Rather, results showed evidence of a significant indirect effect in that being Canadian-born increases the odds of being a sinister right-hander and in turn leads to greater performance across each offensive performance statistic. Collectively, findings provide further support for the hockey influence on batting hypothesis and suggest this effect extends to offensive performance.
Marty Weitzman’s Noah’s Ark Problem
> Marty Weitzman passed away suddenly yesterday. He was on many people’s shortlist for the Nobel. His work is marked by high-theory applied to practical problems. The theory is always worked out in great generality and is difficult even for most economists. Weitzman wanted to be understood by more than a handful of theorists, however, and so he also went to great lengths to look for special cases or revealing metaphors. Thus, the typical Weitzman paper has a dense middle section of math but an introduction and conclusion of sparkling prose that can be understood and appreciated by anyone for its insights.
> The Noah’s Ark Problem illustrates the model and is my favorite Weitzman paper.
Engagement Is the Enemy of Serendipity
> Whenever I’m grumpy about an update to a technology I use, I try to perform a self-audit examining why I’m unhappy about this change. It’s a helpful exercise since we are all by nature resistant to even minor alterations to the technologies we use every day (which is why website redesign is now a synonym for bare-knuckle boxing), and this feeling only increases with age. Sometimes the grumpiness is justified, since one of your tools has become duller or less useful in a way you can clearly articulate; other times, well, welcome to middle age.
> The New York Times recently changed their iPad app to emphasize three main tabs, Top Stories, For You, and Sections.
> So one way of extending political time horizons and increasing is to age-weight votes. The idea is that younger people would get more heavily weighted votes than older people, very roughly in proportion with life expectancy.
I suspect this has very little chance of becoming reality.
Why Nasa’s next Moon mission can’t be an Apollo retread
> There is a familiar question asked of politicians, entrepreneurs and innovators: if you were to do it all again, what would you do differently?
> At Nasa headquarters, they’re fielding almost the opposite inquiry. Why don’t you just do it the same? If you managed to put Neil Armstrong and Buzz Aldrin on the Moon five decades ago, why is it so hard to do it now?
> My other visit here was thirty years ago, and most of all I am surprised by how little has changed. The architecture now looks all the more retro, the alleyways all the more noir, and the motorbikes have by no means vanished. Yes there are plenty of new stores, but overall it is recognizably the same city, something you could not say about Seoul.

Emily Wilson on Translations and Language
> In a recent Twitter thread, Emily Wilson listed some of the difficulties of translating Homer into English. Among them: “There aren’t enough onomatopoeic words for very loud chaotic noises” (#2 on the list), “It’s very hard to come up with enough ways to describe intense desire to act that don’t connote modern psychology” (#5), and “There is no common English word of four syllables or fewer connoting ‘person particularly favored by Zeus due to high social status, and by the way this is a very normal ordinary word which is not drawing any special attention to itself whatsoever, beyond generic heroizing.’” (#7).
> Using Twitter this way is part of her effort to explain literary translation. What do translators do all day? Why can the same sentence turn out so differently depending on the translator? Why did she get stuck translating the Iliad immediately after producing a beloved translation of the Odyssey?
> She and Tyler discuss these questions and more, including why Silicon Valley loves Stoicism, whether Plato made Socrates sound smarter than he was, the future of classics education, the effect of AI on translation, how to make academia more friendly to women, whether she’d choose to ‘overlive’, and the importance of having a big Ikea desk and a huge orange cat.
Mistakes, we’ve drawn a few
> At The Economist, we take data visualisation seriously. Every week we publish around 40 charts across print, the website and our apps. With every single one, we try our best to visualise the numbers accurately and in a way that best supports the story. But sometimes we get it wrong. We can do better in future if we learn from our mistakes — and other people may be able to learn from them, too.

Mammalian Near-Infrared Image Vision through Injectable and Self-Powered Retinal Nanoantennae
> Vision is an essential sensory modality for humans. Our visual system detects light between 400 and 700 nm (Dubois, 2009, Wyszecki and Stiles, 1982, Schnapf et al., 1988), so called visible light. In mammalian photoreceptor cells, light absorbing pigments, consisting of opsins and their covalently linked retinals, are known as intrinsic photon detectors. However, the detection of longer wavelength light, such as near-infrared (NIR) light, though a desirable ability, is a formidable challenge for mammals. This is because detecting longer wavelength light, with lower energy photons, requires opsins (e.g., human red cone opsins) to have much lower energy barriers. Consequently, this results in unendurable high thermal noise, thus making NIR visual pigments impractical (Ala-Laurila et al., 2003, Baylor et al., 1980, Luo et al., 2011, St George, 1952). This physical limitation means that no mammalian photoreceptor can effectively detect NIR light that exceeds 700 nm, and mammals are unable to see NIR light and to project a NIR image to the brain.
> To this end, the successful integration of nanoparticles with biological systems has accelerated basic scientific discoveries and their translation into biomedical applications (Desai, 2012, Mitragotri et al., 2015). To develop abilities that do not exist naturally, miniature nanoscale devices and sensors designed to intimately interface with mammals including humans are of growing interest. Here, we report on an ocular injectable, self-powered, built-in NIR light nanoantenna that can extend the mammalian visual spectrum to the NIR range. These retinal photoreceptor-binding upconversion nanoparticles (pbUCNPs) act as miniature energy transducers that can transform mammalian invisible NIR light in vivo into short wavelength visible emissions (Liu et al., 2017, Wu et al., 2009). As sub-retinal injections are a commonly used ophthalmological practice in animals and humans (Hauswirth et al., 2008, Peng et al., 2017), our pbUCNPs were dissolved in PBS and then injected into the sub-retinal space in the eyes of mice. These nanoparticles were then anchored and bound to the photoreceptors in the mouse retina.

Too Ugly to Be Saved? Singapore Weighs Fate of Its Brutalist Buildings
> Others see them as important markers of national identity because they were designed by a generation of up-and-coming local architects just after the city-state’s founding in 1965, when the area’s growth was fueled by large-scale urban renewal projects. But a few prominent Brutalist landmarks are on the verge of being sold to private developers, which has prompted a last-ditch scramble by enthusiasts to have the buildings protected by conservation laws. It has also set off a thorny debate about what type of architecture is worth saving in the first place.

Eric Schmidt on the Life-Changing Magic of Systematizing, Scaling, and Saying “Thanks”
> Tyler questioned Schmidt about underused management strategies, what Google learned after interviewing one job candidate sixteen times, his opinion on early vs. late Picasso, the best reform in corporate governance, why we might see a bifurcation of the Internet, what technology will explode in the the next 10 years, the most underrated media source, and more.
> Well, turns out there were a few extra credit cards in the company floating around, and random things were showing up. This is how I ran things. But it’s important not to go to the person who bought the telephone booth and say, “You’re fired.” The important thing to do is take their credit card away.
> As a general rule, I try to blame the Internet for everything because everyone else does, and I think some of this is true and some of it’s false. That was a joke by the way. And you can’t joke anymore in the age of Twitter.
