hortly before the dreadful crash of Germanwings Flight 9525, I happened to be reading part of “The Second Machine Age,” a book by two academics at M.I.T., Erik Brynjolfsson and Andrew McAfee, about the coming automation of many professions previously thought of as impervious to technological change, such as those of drivers, doctors, market researchers, and soldiers. With the advances being made in robotics, data analysis, and artificial intelligence, Brynjolfsson and McAfee argue, we are on the cusp of a third industrial revolution.

If prolonged isolation is—as research and experience have confirmed for decades—so objectively horrifying, so intrinsically cruel, how did we end up with a prison system that may subject more of our own citizens to it than any other country in history has?

A 1,000-year-old treatment for eye infections could hold the key to killing antibiotic-resistant superbugs, experts have said.Scientists recreated a 9th Century Anglo-Saxon remedy using onion, garlic and part of a cow's stomach.

There are approximately seven billion inhabitants of earth. They conduct their lives in one or several of about seven thousand languages—multilingualism is a global norm. Linguists acknowledge that the data are inexact, but by the end of this century perhaps as many as fifty per cent of the world’s languages will, at best, exist only in archives and on recordings. According to the calculations of the Catalogue of Endangered Languages (ELCat)—a joint effort of linguists at the University of Hawaii, Manoa, and at the University of Eastern Michigan—nearly thirty language families have disappeared since 1960. If the historical rate of loss is averaged, a language dies about every four months.

Lately, Johnson draws for pleasure, but for three decades she had a happily hectic career as an illustrator, sometimes presenting clients with dozens of sketches a day. Her playful watercolors once adorned packages of Lotus software; for a program called Magellan, she created a ship whose masts were tethered to billowing diskettes. She made a popular postcard of two red parachutes tied together, forming a heart; several other cards were sold for years at MOMA’s gift shop. Johnson produced half a dozen covers for this magazine, including one, from 1985, that presented a sunny vision of an artist’s life: a loft cluttered with pastel canvases, each of them depicting a fragment of the skyline that is framed by a picture window. It’s as if the paintings were jigsaw pieces, and the city a puzzle being solved. Now Johnson is obsessed with making puzzles. Many times a day, she uses her grids as foundations for elaborate arrangements of letters on a page—word searches by way of Mondrian. For all the dedication that goes into her puzzles, however, they are confounding creations: very few are complete. She is assembling one of the world’s largest bodies of unfinished art.

Decades after foot-binding was outlawed in China, a British photographer has met some of the last women subjected to the practice. It was with a sense of pride that Su Xi Rong revealed her feet to British photographer Jo Farrell. Her feet, bound from the age of seven, were so small that she had been renowned for their beauty. The 75-year-old is among the last remaining women in China to bear the effects of foot-binding, a practice first banned in 1912. Farrell met more than 50 of them over an eight-year period, and says she was surprised to find stories of pride and empowerment. Her book about the women is being launched at the British Council in Hong Kong on Monday. Foot-binding was believed to create a more beautiful foot and promote obedience.

“English is not a language in India,” a friend once told me. “It is a class.” This friend, an aspiring Bollywood actor, knew firsthand what it meant to be from the wrong class. Absurd as it must sound, he was frequently denied work in the Hindi film industry for not knowing English. “They want you to walk in the door speaking English. Then if you switch to Hindi, they like it. Otherwise they say, ‘the look doesn’t fit.’ ” My friend, who comes from a small town in the Hindi-speaking north, knew very well why his look didn’t fit. He knew, too, from the example of dozens of upper-middle class, English-speaking actors, that the industry would rather teach someone with no Hindi the language from scratch than hire someone like him.

From primary school to university, I witnessed countless such public humiliations: for fighting, cheating or petty misdemeanors. Caught committing any of these offenses and you may have to stand before the student body, criticizing your own “moral flaws,” condemning your character defects, showing yourself no mercy, even exaggerating your faults. Only those who have endured it can know the depth of shame one feels.

A school in New York state has apologised after receiving complaints because a student recited the US Pledge of Allegiance in Arabic. The school's foreign language department arranged for the pledge to be read in a different language each day for a week. Complaints were received from people who lost family in Afghanistan and from Jewish parents, an official said. Neither the US nor New York state has an official language.

About 300 people have been arrested in the Indian state of Bihar, authorities say, after reports emerged of blatant cheating in school exams. Parents and friends of students were photographed climbing school walls to pass on answers. Many of those arrested were parents. At least 750 students have been expelled. An estimated 1.4m students are taking their school leaving exams in Bihar alone - tests seen as crucial for their chances of a successful career. The authorities have clearly been embarrassed by the cheating, the BBC's Jill McGivering says, with the episode prompting ridicule on social media.

More than two decades before Brittany Maynard’s public advocacy for death with dignity inspired lawmakers in Washington, D.C., and at least 16 states to introduce legislation authorizing the medical practice of aid in dying for the terminally ill, Senator Frank Roberts of Oregon sponsored one of the nation’s first death-with-dignity bills.

He's here to illustrate one of his more provocative experiments - who is more likely to stop for pedestrians, the rich or the poor?

Entertaining the idea of a peculiar long number such as pi puts me in mind of its cousins twice removed, prime numbers, which have so many strange properties. Prime numbers are those numbers, such as 3, 5, 7, 11, and so on, that can be cleanly divided only by one and themselves. Primes and pi suggest a benign infinity, a pleasing order—pi because of its endlessness and its relation to the circle, and primes because no matter how far you travel on the number line you will always encounter a prime, as Euclid proved in 300 B.C. Recently, Yitang Zhang solved a problem involving prime numbers called bounded gaps that had been open for more than a hundred years. Zhang proved that no matter how far you go on the number line, even to the range where the numbers would fill many books, there will, on an infinite number of occasions, be two prime numbers within seventy million places of each other. (Other mathematicians have reduced this gap to two hundred and forty six.) Before, it had not been known whether any such range applied to prime numbers, which seem to behave, especially as they get larger, as if they appear at random.

“Non-overlapping magisteria” has a nice ring to it. The problem is that there are many religious claims that not only “overlap” with empirical data but are incompatible with it. As a scientist who also spends a fair amount of time in the public arena, if I am asked if our understanding of the Big Bang conflicts with the idea of a six-thousand-year-old universe, I face a choice: I can betray my scientific values, or encourage that person to doubt his or her own beliefs. More often than you might think, teaching science is inseparable from teaching doubt.

Reading the scientific research, I learn that the brain starts deteriorating from the mid-20s onwards. By our 40s and 50s, it's well under way. The changes include a drop in brain volume, loss of myelin integrity, cortical thinning, impaired receptor binding and signalling, and altered concentrations of various brain metabolites. The accumulation of neuro-fibrillary tangles, something we associate with Alzheimer's, also happens in normal ageing.

An Afghan artist has been forced into hiding after receiving death threats for dressing in a metal suit featuring exaggerated breasts and buttocks. Kubra Khademi wore the unusual armour in a performance on the streets of Kabul to highlight the problems of sexual harassment faced by women. She had hoped to make a walk lasting for 10 minutes but in the event was forced back into her car by an angry mob of men after only eight minutes. The men threw things and even children were shouting at her.

Seventy years ago on the night of 9-10 March, in the Japanese capital, 334 American B-29 bombers dropped thousands of tonnes of incendiary bombs on the city's crowded wooden neighbourhoods. They started a fire storm that burned at over 1,000 degrees and killed more than 100,000 people.It was an event that dwarfed even the atomic bombing of Hiroshima, yet it's been all but forgotten around the world - even in Japan.

Newton's laws are astonishingly successful at describing the world. They explain why apples fall from trees and why the Earth orbits the Sun. But they have an odd feature: they work just as well backwards as forwards. If an egg can break, then Newton's laws say it can un-break.This is obviously wrong, but nearly every theory that physicists have discovered since Newton has the same problem. The laws of physics simply don't care whether time runs forwards or backwards, any more than they care about whether you're left-handed or right-handed.But we certainly do. In our experience, time has an arrow, always pointing into the future. "You might mix up east and west, but you would not mix up yesterday and tomorrow," says Sean Carroll, a physicist at the California Institute of Technology in Pasadena. "But the fundamental laws of physics don't distinguish between past and future."

Medicine has long known about the placebo effect – the healing power of good expectations. But the nocebo effect, as its evil twin is known, may be more powerful. “It’s easier to do harm than good,” explains Watts. “And this is worrisome, because nocebo’s negative influence can be found lurking in almost every aspect of medical life and beyond.”

Whatever the probes find, it probably won’t help untangle the tortuous reasoning that led to Pluto and Ceres being labelled as dwarf planets in the first place. That happened in 2006, a few months after New Horizons launched and about a year before Dawn did, at a meeting of the International Astronomical Union, the organization that is in charge of classifying and naming celestial objects. The I.A.U. defines a dwarf planet according to four criteria: it must orbit the sun, it must be spherical, it must not be a satellite of another planet, and it must not have “cleared the neighborhood” of other objects of comparable size. Ceres has a diameter of fewer than six hundred miles, Pluto of about fourteen hundred miles. By comparison, Mercury, now the smallest official planet in our solar system, is more than three thousand miles across. So it’s not unreasonable, Stern says, to call Pluto both a planet and a dwarf, provided that one doesn’t cancel out the other. “I’m the one who originally coined the term ‘dwarf planet,’ back in the nineteen-nineties,” he told me. “I’m fine with it. But saying a dwarf planet isn’t a planet is like saying a pygmy hippopotamus isn’t a hippopotamus. It’s scientifically indefensible.”
