Natalie Healey in Scientific American:
Landmark studies such as these laid the groundwork for the introduction of dietary guidelines in the United States and the United Kingdom during the 1970s and 1980s. The recommendations advised citizens to reduce their consumption of saturated fat to about 10% of their total energy intake, to lower cholesterol in the blood and therefore decrease the chances of a heart attack. In the public consciousness, a low-fat diet has been synonymous with good health ever since.
Uffe Ravnskov, a Danish independent researcher based in Lund, Sweden, dismisses the relationship between dietary fats, cholesterol and coronary heart disease, calling it “the greatest medical scandal in modern time”. Critics such as Ravnskov say data points in Keys’ Seven Countries Study were cherry-picked to fit the conclusion. For instance, Keys did not include data from France, where the occurrence of heart disease was comparatively low at the time despite the nation’s high-fat diet. Ravnskov’s The International Network of Cholesterol Skeptics, which has around 100 members—some of them cardiologists—says millions of people have been “badgered” into eating a “tedious and flavorless diet” out of fear for their hearts.

To understand how a frumpy, mustard-coloured, short-handled purse, which may or may not be leather, sold at auction in February for a whopping $32,000, it’s helpful to wander back to ancient Greece. According to Herodotus, the 5th century tyrant Histiaeus was the first to shave the head of an illiterate servant, have his scalp tattooed with a message, allow time for the hair to grow back, then send the poor fellow out to his destination, where a second head shaving waited.
No woman could get away with it. Murdering her children is all she would ever be known for—ask Medea. Yet Herakles, often called by his Roman name, Hercules, is known for everything else: slaying the man-eating birds of the Stymphalian marsh, the multiheaded Lernaean Hydra, and the Nemean lion, with its Kevlar-strength fur; capturing the wild Erymanthian boar, the golden-antlered deer of Artemis, and the Minotaur’s father; stealing the girdle of Hippolyta, the golden apples from the garden of the Hesperides, the flesh-eating mares of Diomedes, and the red cattle of the giant Geryon; mucking the Augean stables in a single day; and kidnapping the three-headed dog Cerberus from Hades.
There’s nothing wrong, of course, with taking one’s Crime and Punishment neat, without footnotes, introduction or weighty biography, sans everything except Dostoevsky’s incandescent text (as recast by your pick of fourteen translators). Countless readers, and all good formalists, have done just that, not least because the old translations tended to have no notes. Why interrupt the spell, the morbid giddiness that overcomes the trusting reader almost as strongly as it does Rodion Raskolnikov, in whose garret and mind we perch throughout the most searing pages of the novel? What’s more, this is a book that many devour when they are roughly the same age as Dostoevsky’s murderer (twenty-three), if not several years younger. Raskolnikov, as we first meet him, is imprisoned by his internal, ever ‘relatable’ struggle with social conventions and family pressures, and his story is in one shocking sense a universal metaphor: we all have our crimes to commit. Who has time for footnotes if your main concern is to determine whether you are with the ‘Lycurguses, Solons, Muhammads, Napoleons’, with those who have the right to transgress and trample over others, or whether you are merely a ‘quivering creature’ or, still worse, a bookish ‘aesthetic louse’?
Peter Singer: I think utilitarianism—far from being a kind of dry economic science or anything like that—is actually a reforming impulse. That goes back a long way before Jeremy Bentham, but was certainly made explicit by Bentham. Bentham and [later] utilitarians have been against slavery, they’ve been for women’s rights. They’ve been for the rights of gay people long before anybody else dared to even talk about that. They’ve been against cruelty to animals. They’ve been for prison reform. There’s a long list of things that utilitarians have been trying to reduce the amount of suffering in relation to and I’m very happy to be part of that tradition and to think of utilitarianism not merely as something for philosophers to talk about, but something that motivates people to act.
As the holidays approach, we are being reminded of the fragility of the global supply chain. But at the same time, the supply chain itself is a truly impressive and fascinating structure, made as it is from multiple components that must work together in synchrony. From building an item in a factory and shipping it worldwide to transporting it locally, processing it in a distribution center, and finally delivering it to an address, the system is simultaneously awe-inspiring and deeply dehumanizing. I talk with Christopher Mims about how things are made, how they get to us, and what it all means for the present and future of our work and our lives.
Epistemology, the philosophical study of knowledge, belief and evidence, starts here, with our fallibility. And from this beginning, there are many paths for epistemology to take, and many sorts of questions to set us down these trails.
Marcus du Sautoy was around 13 when the exploits of a 19th-century German math genius changed his life. According to legend, the young Carl Friedrich Gauss was asked to calculate the sum of the numbers from one to 100, but instead of adding up the digits one by one, he realized 50 pairs of numbers (one plus 100, two plus 99, and so on) all equaled 101. So, he simply multiplied 50 times 101 and dropped the correct answer, 5,050, on his teacher’s desk.
Prof Crowther, who grew up in Prestatyn, Flintshire, is a professor of ecosystem ecology at ETH Zurich University in Switzerland and also chairs an advisory board for the United Nations on nature restoration. He warned blanket planting of trees was “hugely threatening”. “This is not about offsetting your guilt, that would be an absolutely devastating step for climate change,” he said. Speaking at
Until recently, Fran Lebowitz was not well known in Britain. The release this year of Martin Scorsese’s Netflix series Pretend It’s a City, however, has made her something of a household name here. A veritable Franbase has now formed in the UK, giving rise to online appearances, a tour scheduled for next year and the first publication in this country of The Fran Lebowitz Reader (which was originally published in the United States in 1994). The Lebowitz on the dust jacket is one fans of the series will recognize: the seasoned New Yorker with gorgeous overcoat, horn-rimmed sunglasses and cigarette, as famous for her writer’s block as for her wit. Between the covers, we meet the artist as a young woman. The Reader reproduces her only two essay collections: Metropolitan Life (1978) and Social Studies (1981), which in turn reproduce her magazine pieces of that era.

With the publication in the United States of his best-selling “Sapiens” in 2015, the Israeli historian and philosopher Yuval Noah Harari arrived at the top rank of public intellectuals, a position he consolidated with “Homo Deus” (2017) and “21 Lessons for the 21st Century” (2018). Harari’s key theme is the idea that human society has largely been driven by our species’s capacity to believe in what he calls fictions: those things whose power is derived from their existence in our collective imaginations, whether they be gods or nations; our belief in them allows us to cooperate on a societal scale. The broad sweep of Harari’s writing, which encompasses the prehistoric past and a dark far-off future, has turned him into a bit of a walking inkblot test. “The general misunderstandings of me,” says Harari, 45, co-author of the recently published “Sapiens: A Graphic History, Volume 2” (the latest in a series of graphic-novel adaptations of his work), “are that I’m the prophet of doom and then there’s this opposite view that I think everything is wonderful.” Both, of course, might be true. “Once the books are out, the ideas are out of your hands,” he says.
The pain struck suddenly in Venice.
One day in 2010, when oncologist Paul Muizelaar operated on a patient with glioblastoma—a brain tumor infamous for its deathly toll—he did something shocking. First, he cut the skull open and carved out as much of the tumor as he could. But before he replaced the piece of skull to close the wound, he soaked it in a solution containing Enterobacter aerogenes,1 bacteria found in feces. For the next month, the patient lay in a coma in an intensive care unit battling the bacteria he was infected with—and then one day a scan of his brain no longer showed the distinctive signature of glioblastoma. Instead, it showed an abscess, which, given the situation, Muizelaar deemed a positive development. “A brain abscess can be treated, a glioblastoma cannot,”
