Zarnkow is one of a group of researchers who over the past few decades have challenged that story. He and others have shown that alcohol is one of the most universally produced and enjoyed substances in history—and in prehistory too, because people were imbibing alcohol long before they invented writing. ... Chemical analysis recently showed that the Chinese were making a kind of wine from rice, honey, and fruit 9,000 years ago. In the Caucasus Mountains of modern-day Georgia and the Zagros Mountains of Iran, grapes were one of the earliest fruits to be domesticated, and wine was made as early as 7,400 years ago. ... All over the world, in fact, evidence for alcohol production from all kinds of crops is showing up, dating to near the dawn of civilization. ... From our modern point of view, ethanol has one very compelling property: It makes us feel good. Ethanol helps release serotonin, dopamine, and endorphins in the brain, chemicals that make us happy and less anxious. ... To our fruit-eating primate ancestors swinging through the trees, however, the ethanol in rotting fruit would have had three other appealing characteristics. First, it has a strong, distinctive smell that makes the fruit easy to locate. Second, it’s easier to digest, allowing animals to get more of a commodity that was precious back then: calories. Third, its antiseptic qualities repel microbes that might sicken a primate.

The brothers oversee an enviable collection of businesses — a movie studio, cable channels and a publishing house worth a combined $62bn. But that does not mean they have nothing to worry about. Their newspapers have been walloped by an industry-wide collapse in print advertising, while Fox’s television networks are grappling with the “cord-cutting” phenomenon — the cancellation of pricey cable subscriptions by a generation that prefers binge-watching on demand. For owners of channels such as Fox that means fewer viewers and pressure on advertising. ... The competition is also beefing up. Time Warner, one of Fox’s main rivals and the owner of HBO, CNN and Warner Bros, has agreed a blockbuster $85.4bn sale to AT&T, which will create a giant that dwarfs Fox. If it is cleared by regulators, the combined company will be able to deliver Time Warner movies and TV programming direct to more than 160 million AT&T customers around the US — something Fox is currently unable to do. ... Add these challenges to the scrutiny and opposition that their Sky deal will generate and the younger Murdochs find themselves in a challenging environment. Their father overcame considerable obstacles to become the world’s most influential media mogul, battling political establishments on both sides of the Atlantic and making risky bets along the way, buying The Sun, launching Sky and Fox News, to name but three. The question now facing James and Lachlan is this: do they have what it takes to fill his shoes?

Consider the number of networked cameras that capture data about you as you go about your day. Surveillance cameras are mounted in offices, stores, public transportation; on city streets, ATM machines, and car dashboards. You or your neighbors may have installed cameras to watch over your front door; you may have a webcam watching over your valuables—perhaps even your children. Security cameras are virtually everywhere, installed both to provide a record if a crime is committed and to deter people from committing a crime in the first place. Based on an exhaustive survey of the number of such cameras in one English county in 2011, it was estimated there were 2 million surveillance cameras in the United Kingdom alone—about one camera for every thirty people. ... Generalizing this to the rest of the world, there are about 100 million cameras watching public spaces, all day and all night. Yet, this is only one-tenth of the 1 billion cameras on smartphones. Within the next few years, there will be one networked camera for every single person on the planet. ... If technology continues to follow Moore’s Law, doubling the computing power available at the same price every 18 months, we will very likely be sharing the world with roughly 1 trillion sensors by 2020, in line with projections from Bosch, HP, IBM, and others. ... If everything is recorded, will it encourage "better" behavior? And how will the lack of any recording be interpreted?

We have a certain heroic expectation of how medicine works. Following the Second World War, penicillin and then a raft of other antibiotics cured the scourge of bacterial diseases that it had been thought only God could touch. New vaccines routed polio, diphtheria, rubella, and measles. Surgeons opened the heart, transplanted organs, and removed once inoperable tumors. Heart attacks could be stopped; cancers could be cured. A single generation experienced a transformation in the treatment of human illness as no generation had before. It was like discovering that water could put out fire. We built our health-care system, accordingly, to deploy firefighters. Doctors became saviors. ... But the model wasn’t quite right. If an illness is a fire, many of them require months or years to extinguish, or can be reduced only to a low-level smolder. The treatments may have side effects and complications that require yet more attention. Chronic illness has become commonplace, and we have been poorly prepared to deal with it. Much of what ails us requires a more patient kind of skill. ... Observing the care, I began to grasp how the commitment to seeing people over time leads primary-care clinicians to take an approach to problem-solving that is very different from that of doctors, like me, who provide mainly episodic care.
