Mischel’s story isn’t surprising—nicotine is addictive, and quitting is difficult—except for one thing: Mischel is the creator of the marshmallow test, one of the most famous experiments in the history of psychology, which is often cited as evidence of the importance of self-control. In the original test, which was administered at the Bing Nursery School, at Stanford, in the nineteen-sixties, Mischel’s team would present a child with a treat (marshmallows were just one option) and tell her that she could either eat the one treat immediately or wait alone in the room for several minutes until the researcher returned, at which point she could have two treats. The promised treats were always visible and the child knew that all she had to do to stop the agonizing wait was ring a bell to call the experimenter back—although in that case, she wouldn’t get the second treat. The longer a child delayed gratification, Mischel found—that is, the longer she was able to wait—the better she would fare later in life at numerous measures of what we now call executive function. She would perform better academically, earn more money, and be healthier and happier. She would also be more likely to avoid a number of negative outcomes, including jail time, obesity, and drug use.

What, really, would Maria Montessori have made of this scene? The 30 or so children here were not down at the shore poking their fingers in the sand or running them along mossy stones or digging for hermit crabs. Instead they were all inside, alone or in groups of two or three, their faces a few inches from a screen, their hands doing things Montessori surely did not imagine. A couple of 3-year-old girls were leaning against a pair of French doors, reading an interactive story called Ten Giggly Gorillas and fighting over which ape to tickle next. A boy in a nearby corner had turned his fingertip into a red marker to draw an ugly picture of his older brother. On an old oak table at the front of the room, a giant stuffed Angry Bird beckoned the children to come and test out tablets loaded with dozens of new apps. Some of the chairs had pillows strapped to them, since an 18-month-old might not otherwise be able to reach the table, though she’d know how to swipe once she did.

The researchers - Peera Wongupparaj, Veena Kumari and Robin Morris at Kings College London - did not themselves ask anyone to sit an IQ test, but they analysed data from 405 previous studies. Altogether, they harvested IQ test data from more than 200,000 participants, captured over 64 years and from 48 countries. Focusing on one part of the IQ test, the Raven's Progressive Matrices, they found that on average intelligence has risen the equivalent of 20 IQ points since 1950. IQ tests are designed to ensure that the average result is always 100, so this is a significant jump.

Leah H. Somerville, a Harvard neuroscientist, sometimes finds herself in front of an audience of judges. They come to hear her speak about how the brain develops.It’s a subject on which many legal questions depend. How old does someone have to be to be sentenced to death? When should someone get to vote? Can an 18-year-old give informed consent?

However, she is not the only person to wake up from a coma speaking another language.Australian Ben McMahon woke up able to speak Mandarin after being involved in a car accident, while a 13-year-old Croatian girl woke up having replaced her fluency in her native language with speaking German. There was also the case of a U.S. navy veteran was found unconscious in a motel room who had no recollection of who he was and woke up speaking fluent Swedish. A Queensland Brain Institute neuroscientist suggested a possible explanation last year. Dr Pankaj Sah said the brain was made up of different circuits - which assist in language, breathing, speaking and thinking - similar to electronic circuits.According to him, it is possible in Ben's case that the parts of the brain which recalled English were damaged in the crash and those that retained Mandarin were activated when the 22-year-old woke up.Whether this is what happened to Ms Jieyu is not known. More commonly, people are known to have woken up with a different accent, like in the case of Kath Locket, who was born and bred in Stafford. But after she was rushed into hospital unable to speak or swallow, she developed a strong accent which was distinctly European.  WHAT IS FOREIGN ACCENT SYNDROME?

“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.

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.

It seems we may all be vulnerable to moral illusions the ethical equivalent of the bending lines that trick the eye on cereal boxes and in psychology textbooks. Illusions are a favorite tool of perception scientists for exposing the workings of the five senses, and of philosophers for shaking people out of the naïve belief that our minds give us a transparent window onto the world (since if our eyes can be fooled by an illusion, why should we trust them at other times?). Today, a new field is using illusions to unmask a sixth sense, the moral sense.

The first hallmark of moralization is that the rules it invokes are felt to be universal. Prohibitions of rape and murder, for example, are felt not to be matters of local custom but to be universally and objectively warranted. One can easily say, “I don’t like brussels sprouts, but I don’t care if you eat them,” but no one would say, “I don’t like killing, but I don’t care if you murder someone.”The other hallmark is that people feel that those who commit immoral acts deserve to be punished.

Until recently, it was understood that some people didn’t enjoy smoking or avoided it because it was hazardous to their health. But with the discovery of the harmful effects of secondhand smoke, smoking is now treated as immoral. Smokers are ostracized; images of people smoking are censored; and entities touched by smoke are felt to be contaminated (so hotels have not only nonsmoking rooms but nonsmoking floors). The desire for retribution has been visited on tobacco companies, who have been slapped with staggering “punitive damages.” At the same time, many behaviors have been amoralized, switched from moral failings to lifestyle choices.

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.

Lifetime readers know that reading literature can be transformative, but they can’t prove it. If they tried, they would have to buck the metric prejudice, the American notion that assertions unsupported with statistics are virtually meaningless. What they know about literature and its effects is literally and spiritually immeasurable. They would have to buck common marketplace wisdom, too: in an economy demanding “skill sets”—defined narrowly as technical and business skills—that deep-reading stuff won’t get you anywhere.
