Every day we hear a story about the movement of stock prices. But the story is different each day. So basically, these stories are made up after the fact. But when we look at it systematically, we don’t see a big effect of Fed actions on real activity or on stock prices or on anything else. That’s why I use to say that the business of central banks is like pornography: In essence, it’s just entertainment and it doesn’t have any real effects.

It is unusual that Xi “does not perceive his power to be completely consolidated, even eight years in,” said Sheena Greitens, a professor of public affairs who studies Chinese approaches to security at the University of Texas at Austin. Xi may be launching this campaign to prepare for 2022, when he will transition into an unprecedented third term, she said.

But a political system prone to crackdowns can turn suspicious and brittle, with everyone afraid to point out problems or admit mistakes. It is what allowed the initial cover-up of a virus spreading in Wuhan last winter, at the cost of thousands of civilian deaths. When things go wrong, however, Xi has used a classic technique: punishing local officials while keeping the emperor free of blame.

Unfortunately, if you want to do new things, you’ll face a force more powerful than other people’s skepticism: your own skepticism. You too will judge your early work too harshly. How do you avoid that?

This is a difficult problem, because you don’t want to completely eliminate your horror of making something lame. That’s what steers you toward doing good work. You just want to turn it off temporarily, the way a painkiller temporarily turns off pain.

Institutions can be mapped across the pace layers diagram as well. Take Apple Computer, for example. They’re coming out with new iPhones every six months, which is the fashion layer. The commerce layer is Apple selling these devices. The infrastructure layer is the cell phone networks and chip fabs that it’s all built on. The governance layer—and note that it is governance, not government; they’re mostly working with governments, but they also have to work with general governing systems. Some of these companies are hitting walls against different types of governments who have different ideas of privacy, different ideas of commercialization, and they’re now having to shape their companies around that. And then obviously, culture is moving slower underneath all of this, but Apple is starting to affect culture. And then there’s the last pace layer, nature, moving the slowest. At some point, Apple is going to have to come to terms with the level of environmental damage and problems that are happening on the nature pace layer if it is going to be a company that lasts for hundreds or a thousand years. So we could imagine any large institution mapped across this and I think it’s a useful tool for that. 

The notion of weaponizing microwaves dates back to the Cold War, when, in 1961, an American biologist named Allan Frey discovered that irradiating a human head with microwaves could produce the sensation of sound—even in deaf ears, even from thousands of feet away. Playing with the frequency and intensity of the microwave beam could produce a range of different sensations in a person. In 2018, Frey told the New York Times that the Soviets took immediate notice of his work and flew him to Moscow, where they squired him around secret military facilities and asked him to give lectures about the effects of microwaves on the brain.

There is a better way, one that would allow the United States to make decisions based not on simplistic extrapolations of the past but on smart estimates of the future. It involves reconciling two approaches often seen to be at philosophical loggerheads: scenario planning and probabilistic forecasting. Each approach has a fundamentally different assumption about the future. Scenario planners maintain that there are so many possible futures that one can imagine them only in terms of plausibility, not probability. By contrast, forecasters believe it is possible to calculate the odds of possible outcomes, thereby transforming amorphous uncertainty into quantifiable risk. Because each method has its strengths, the optimal approach is to combine them. This holistic method would provide policymakers with both a range of conceivable futures and regular updates as to which one is likely to emerge. For once, they could make shrewd bets about tomorrow, today.

The atomic bomb marked the end of the Second World War and the beginning of the Cold War. The creativity of Manhattan Project scientists and engineers has been abundantly celebrated by later commentators, not so much in the immediate aftermath: the word ‘creativity’ doesn’t appear in the official Smyth Report (1945) on the Project. And the only invocation of the notion of genius is deflationary and morally exculpatory: ‘This weapon has been created not by the devilish inspiration of some warped genius but by the arduous labour of thousands of normal men and women.’ But the new atomic world was just the institutional and cultural environment in which creativity emerged, flourished and was variously interpreted.

Ancient Egyptians were an African people who created a distinctive, stable, and long-lasting civilization in the Nile Valley by at least 4400 BCE. They believed that images — objects representing the human form, rendered in stone, metal, wood, clay, or even wax—could be activated to host a supernatural power. This power could be either divine or the soul of a deceased human who had become divine at death. The occupied image was a meeting point between the supernatural and the terrestrial. It was also a physical body enabling such powers to act in our material world. Without an image, supernatural forces could not intervene in events on earth.

When the hapless JFK is assassinated in 1963, it seems that America may be on the losing side of history. The USSR has put a man in space, extended its influence in Latin America and it also has a large nuclear arsenal in the American SSR. The explosion of the Apollo 11 rocket on the launchpad in 1969, killing everyone on board, set against a background of civil unrest and the disastrous war in Vietnam, becomes a bitterly potent symbol of a nation that has lost its way. A year later Alexei Leonov, the first man to walk in space, becomes the first man to walk on the moon.

Advocates of psilocybin-assisted therapy tout it as the solution to the burgeoning mental health crisis. But, like MDMA, psilocybin is far from a culturally neutral drug, carrying both the shame of Schedule 1 status and a checkered social history. It too may need to build the kind of politically heterogeneous coalition of supporters that MDMA-assisted therapy enjoys.

But to generate a breadth of appeal, one challenge stands out: psilocybin seems to make people more liberal. Scientific reports associating psychedelic use and liberal values stretch back as far as 1971, and although these findings have been replicated more recently, a noncausal explanation is readily available. Those with conservative attitudes tend to look more disapprovingly on illicit drug use, making them less likely than liberals to try a psychedelic drug in the first place.

An injured plant also produces traumatic acid, known as the “wound hormone,” which stimulates cell division to close up a laceration in much the same way that blood clots in an animal’s wound. These responses happen within minutes of attack: Plants begin patching themselves up while still fighting off invaders. A plant must therefore constantly decide how to divide its resources between defense and regeneration.

Cats do have a highly developed sense of savory taste—dubbed umami in Japanese (delicious savory taste)—and this makes sense because they are consuming protein all the time. What would it be like to eat meat with a cat’s tongue? It’s impossible for science to say for certain, but one can imagine for a sensory system specifically tuned to taste savory flesh, it must be delicious.

On the other hand, you would never want to eat a salad with a cow’s tongue because cows eat grass all day—something they would never be able to do if they were actually able to taste it the way we do. Unlike humans, with our dozens of bitter receptors, cows are highly insensitive to bitter foods. They still detect it, but apparently not so well.

It is estimated that roughly ⅓ of the world’s ~15m vending machines are located in the US.

Of these 5m US-based vending machines, ~2m are currently in operation, collectively bringing in $7.4B in annual revenue for those who own them. This means that the average American adult spends ~$35 per year on vending machine items.

What makes the vending industry truly unique is its stratification: The landscape is composed of thousands of small-time independent operators — and no single entity owns >5% of the market.

The encouraging feature of chicken sexing is that the process, although mysterious, is quickly learned. As a result, knowing what the brain does when it accurately determines the sex of a bird could soon bear on how soldiers distinguish friend from foe in combat, how doctors make accurate diagnoses, how bird watchers identify species on the wing, how scientists interpret seismic data, and even how kids learn to read. Industrial sexers are worth investigating because, as quickly trained experts who have to make split-second decisions, the way they learn to see chicken genitals might one day help clarify how the rest of us learn to see the world.

Fear is a powerful force not just for wintering dunlins, but across the natural world. Ecologists have long known that predators play a key role in ecosystems, shaping whole communities with the knock-on effects of who eats whom. But a new approach is revealing that it’s not just getting eaten, but also the fear of getting eaten, that shapes everything from individual brains and behaviour to whole ecosystems. This new field, exploring the non-consumptive effects of predators, is known as fear ecology.

But the true leaps in efficiency were achieved by new craft, which airlines began to request from manufacturers in the early 00s. The Boeing 787, for example, claims to burn 20% less fuel than its older sibling, the 767. Van Hooff recalled how, when KLM inducted its first 787 into its fleet in 2015, a pilot accustomed to the 747 was appointed to fly it to Dubai. “The 747 is beautiful, but it burns around 11,000 kilos of fuel per hour on a trip like this, so he was used to seeing around 100,000 kilos on his storage gauge when he got into the cockpit,” Van Hooff said. “This time, he saw 50,000. He put in a call to dispatch to ask: ‘Are you really sure this is enough?’ Of course, he knew it was. But he couldn’t get past his gut feeling that he needed more fuel.”

The reason we gain or lose weight is much less mysterious if we keep track of all the kilograms, too, not just those enigmatic kilojoules or calories.

According to the latest government figures, Australians consume 3.5kg of food and beverages every day. Of that, 415 grams is solid macronutrients, 23 grams is fibre and the remaining 3kg is water.

What’s not reported is that we inhale more than 600 grams worth of oxygen, too, and this figure is equally important for your waistline.

A vaccine is, in essence, a trick—a sleight of hand that convinces your body to mount a counterattack to a given pathogen before that pathogen actually infects you. There are various ways to pull the trick off: vaccines can be made with a weakened virus, or a killed virus, or just a key part of the virus, or a part of the virus piggybacking on a different, benign virus, or an instruction manual for making that part of the virus yourself. In each approach, you get the benefits of an immune response without the messy business of a disease.

Advances in the study of plant silica micro-fossils (phytoliths) have helped trace banana cultivation from the Island of New Guinea more than 7,000 years ago – from where it spread through Island Southeast Asia, and eventually across the Indian Ocean to Africa, more than a millennium before Vasco da Gama navigated from Africa to India. These techniques have also revealed unforeseen agricultural origins – such as the forgotten cereal, browntop millet. It was the first staple crop of South India, before it was largely replaced by crops such as sorghum that were translocated from Africa. Many people might be surprised to learn that the early farming tradition in the Mississippi basin relied on pitseed goosefoot, erect knotweed and marsh elder some 3,000-4,000 years ago, long before maize agriculture arrived in the American Midwest.

Why Iceland?  Because it was founded in the late-9th century by Vikings, and when they arrived the island was uninhabited except for possibly a handful of monks who did not stay.  This means it has been populated almost entirely by its original Norse inhabitants and their descendants. Iceland’s President Guðni Th. Jóhannesson acknowledged to me that this set up the conditions for the creation of a unique society because, compared to a country like the U.S., Iceland has had the benefit of developing free from the guilt of having displaced native inhabitants to do so. As a result, almost 100% of Icelanders today can trace their genes to their Viking founders. This is unusual in the western world and has given Iceland the distinction of having one of the most homogenous gene pools in the world.

We can trace the Seven Wonders back to Herodotus, an Athenian scholar who set out circa 450 BC to write a history of the then-recently concluded Greco-Persian Wars; such, that is, was his ostensible purpose. But Herodotus was, bless his heart, a curious sort, and as he traveled all over the ancient world in the course of his research he just couldn’t resist writing down all of the interesting things he saw and heard about. Thus, in addition to being a massively important historical text, the only source we have describing countless pivotal events, Herodotus’s Histories can also be seen as the world’s first travel memoir. We know that he distilled from his longer work a list of Wonders of the World, presumably the first ever of its kind, but it exists today only as a passing reference in other works; the last extant copies of it were likely burned along with the Library of Alexandria during the early centuries after Christ. His bucket list would, needless to say, make for fascinating reading today.
