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.

Why Are the Noses Broken on Egyptian Statues?

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.

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.

Does the medieval past affect the present? In Iceland it does

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.

The idea of detecting life through an otherwise inexplicable anomaly in a planet’s spectrum dates back to the 1960s, when it was given voice by James Lovelock, a British chemist and inventor. It came into its own when astronomers started discovering planets around other stars, or exoplanets. Most of these planets are in inhospitably unearthlike orbits, but some sit within what astronomers call the “habitable zone”—the zone in which, under various conditions, the surface might support liquid water. Astrobiologists like Sara Seager of MIT started putting real effort into working out what anomalous gases might be visible once they got telescopes good enough to analyse the spectra of such planets’ atmospheres.

A few years ago some of the scientists who work with Dr Seager and in her team started to get interested in phosphine. Though it is not clear how microbes make it, or something which decomposes into it, its association with life is pretty clear (among other things, penguin guano seems rich in the stuff). There seem to be no appreciable mechanisms for making it abiotically either in the depths of the Earth or through the “photochemical” reactions driven by sunlight which create other short-lived gases in the atmosphere. And it has some nice distinct spectral lines which should be eventually observable in the infrared light from some sorts of exoplanet.

But what if Nero wasn’t such a monster? What if he didn’t invent the spectator sport of throwing Christians to the lions in the Colosseum? What if he wasn’t the tyrant who murdered upstanding Roman senators and debauched their wives? Indeed, what if the whole lurid rap sheet has been an elaborate set-up, with Nero as history’s patsy? After all, we have no eyewitness testimony from Nero’s reign. Any contemporaneous writings have been lost. The ancient Roman sources we do have date from considerably after Nero’s suicide in A.D. 68. The case against Nero, then, is largely hearsay, amplified and distorted over two millennia in history’s longest game of telephone. Besides, no one really wants to straighten out the record. Who wants another version of Nero? He’s the perfect evil tyrant just the way he is.

The impact theory is in some senses comforting. We have big telescopes, we can see into space now, in theory, if we knew an impact event was coming, we could prevent it. If it takes an impact to cause a catastrophic melting and sea level rise event, then we’re mostly safe from it happening. If the melting was caused by an impact, then it means our current climate models which estimate around a meter of sea level rise by the year 2100, are largely accurate.

But if these melting spikes were not caused by an impact, then it means something on earth which we currently do not understand triggered them. Something caused the ice sheets to suddenly and rapidly destabilize and release a large quantity of meltwater over a relatively brief period. If such an event were to occur today, the effects would be globally catastrophic. If an event caused a one-meter sea level rise over the course of a few years, it would render many of the world’s coastal cities uninhabitable.

In 1803, the [Spanish] king, convinced of the benefits of the vaccine, ordered his personal physician Francis Xavier de Balmis, to deliver it to the Spanish dominions in North and South America. To maintain the vaccine in an available state during the voyage, the physician recruited 22 young boys who had never had cowpox or smallpox before, aged three to nine years, from the orphanages of Spain. During the trip across the Atlantic, de Balmis vaccinated the orphans in a living chain. Two children were vaccinated immediately before departure, and when cowpox pustules had appeared on their arms, material from these lesions was used to vaccinate two more children.

If the Norse did reach Chichén Itzá, how did they get there? A possible Viking ship appears in a mural in a different building called Las Monjas, or ‘The Nunnery’. (The Spaniards assumed that any building with a large courtyard nearby had to be a nunnery, but the Maya had no nunneries.) Built before 950 CE, the Nunnery contains murals that might have been painted slightly later.

One Nunnery mural shows no captives but depicts a boat with clearly delineated planks, or strakes. The use of planks indicates that the Nunnery boat couldn’t have been a local craft because the Maya, like most of the peoples living in the Americas, made their canoes by burning and hollowing out tree trunks. Only one Amerindian people ever made boats with sewn planks, the Chumash, who lived in modern-day Santa Barbara, California. The sharply outlined strakes in this mural are better evidence of Norse presence at Chichén Itzá than the paintings of the blond-haired captives.

Improving the intellectual and moral quality of people going into government strengthens modern electorates’ faith in its leaders and handing some power from electorates to experts can also strengthen the core of democracy – or as an American academic, Gareth Jones, has put it, 10% less democracy can be better democracy. Giving independence to central banks has kept inflation under control; Sweden’s decision to ask specialists to review the pension system to prevent it from going bankrupt has put the public finances on a sound foundation (not something that can be said of the United States which contemplated a Swedish-style solution but backed out at the last moment). Plato’s most important insights hold true regardless of his strictures about democracy: that government matters immensely – and can make all the difference between a society thriving or going into decline.

The Covid-19 crisis has shocked us by revealing the weakness of Western government, particularly in the United States and Britain, and the strength of the Chinese government.

Within Mount Vesuvius, a dangerous process is beginning to take place. Because the gassiest magma exits first, as the eruption enters its later phases, less gas is forced through Vesuvius’ vent and its jet loses power. This may sound like a positive development. It is not. Instead of rising miles into the atmosphere, the dense mix of searing hot ash and gas will rise only a few hundred yards and then fall, picking up velocity so that when it reaches the ground, it hugs and flows like a superheated sandstorm moving at autobahn speeds. These “pyroclastic flows” can be 1,800 degrees F, dense enough to suffocate you, and they flow for miles. In the early morning hours of the 25th, a surge will kill everyone remaining in Pompeii. You need to leave long before then.

As to where to go, you have two choices. Mountains block your path to the east, and the Mediterranean Sea blocks your escape to the west. You could try to wait for a boat at the beach, but (a) archaeologists have found a large group of bodies in a boathouse in nearby Herculaneum who appear to have attempted that, (b) the prevailing winds are against you, and (c) tsunamis.

In part, the Taiwanese government’s multi-faceted communications strategy reflects an attempt to make up for past mistakes. The government’s mishandling of the SARS epidemic in 2003, which had a lower case count but a higher death rate than COVID-19, severely undermined public trust at the time. Unaware of the highly infectious nature of SARS, one woman’s visit to an emergency room set off a chain of transmission that spiraled out of control. In a desperate attempt to contain the virus, the government sealed off Hoping Hospital, with more than 1,000 people, infected and uninfected, locked inside. The inhumaneness of the approach shocked Taiwanese citizens. Twu Shiing-jer, Taiwan’s Minister of the Department of Health, resigned in the aftermath.

Post-SARS, Taiwan immediately began planning for the next health crisis. It could not afford to be caught off-guard again—especially since it had been clear during the SARS epidemic that Taiwan would have little to no direct communication with the World Health Organization, because it is not a member. Taiwan is isolated, and on its own. This realization may have proven decisive in its pandemic response, as Taiwan was one of the earliest countries to sound the alarm on COVID-19 and begin monitoring the virus

There’s a part of the brain called the fusiform, which is in the frontal lobe, I believe. It’s the part of the brain that recognizes faces—everyone has it—but there’s something weird about my one. It’s something you’re born with and something you can’t learn. It’s a scale. There are people called prosopagnosics who can’t recognize faces whatsoever. That’s how it all came to be discovered. People with face blindness don’t recognize their own face in the mirror, or their mums or their dads. It’s a really awful thing. From that far end of the scale, you have people on the other end and those are the super recognizers.

Maguire has been tackling stuttering from a very different angle: investigating the role of dopamine, a key signaling molecule in the brain. Dopamine can ramp up or down the activity of neurons, depending on the brain location and the nerve receptors it sticks to. There are five different dopamine receptors (named D1, D2, and so on) that pick up the signal and respond.

During the 1990s, Maguire and colleagues were among the first to use a certain kind of brain scan, positron emission tomography, on people who stutter. They found toomuch dopamine activity in these people’s brains. That extra dopamine seems to stifle the activity of some of the brain regions that Chang and others have linked to stuttering.
