In London's art gallery six or seven men, mostly in their 30s, are busy painting the walls with new designs in colorful lettering and clever tricks. Tins of spray paint and beer stand on the ground. The atmosphere is not unlike that of a golf course: a mix of concentration and relaxation.

    Graffiti(涂鸦) painting is traditionally a daring hobby. Teenagers avoid security guards to put their names on trains and buses. But over the past decade that has almost disappeared from Britain's cities. Between 2007 and 2017 the number of incidents of graffiti recorded by the British Transport Police fell by 63%. A survey by the environment ministry shows that fewer places are damaged by tags(绘名) than ever. Graffiti are increasingly limited to only a few walls. In time the practice may die out entirely.

    The most obvious reason for the decline in tagging and train-painting is better policing, says Keegan Webb, who runs The London Vandal, a graffiti blog (博客). Numerous cameras mean it is harder to get away with painting illegally. And punishments are more severe. A generational change is apparent, too. Now teenagers prefer to play with iPads and video games. Those who do get involved tend to prefer street art to graffiti. And the internet helps painters win far more attention by posting pictures online than they can by breaking into a railway yard.

    Taggers and graffiti artists mostly grew up in the 1980s and 1990s. Those men are now older and less willing to take risks. "We can't run away from the police any more," says Ben Eine, who turned from tagging to street art. The hip-hop culture that inspired graffiti in the first place has faded. Video games and comic books provide more inspiration than music.

    Graffiti may eventually disappear. But for now the hobby is almost respectable. Mr Eine says he has lots of friends who used to paint trains. Now with wives and children, they paint abandoned houses at the weekend. It has become something to do on a Sunday afternoon—a slightly healthier alternative to sitting watching the football.

    Are you a different person when you speak a foreign language? That's just one of the questions the New Yorker's writer and native North Carolinian Lauren Collins explores in her autobiography, about her tough efforts to master French after marrying a Frenchman whose name —Olivier—she couldn't even pronounce properly. When in French ranges from the humorously personal story to a deeper look at various theories of language acquisition and linguistics (语言学).

    The couple met in London “on more or less neutral ground: his continent, my language.” But the balance shifted when they moved to Geneva for Olivier's work. The normally voluble (健谈的) Collins found herself at a loss — “nearly speechless.” The language barrier, and her dependence on her husband for simple things like buying the right cut of meat worsened her mixed feelings about “unlovely, but not ridiculous” Geneva. She comments, “Language, as much as land, is a place__To be cut off from it is to be, in a sense, homeless.”

    Her sense of alienation (疏离感) leads to an examination of America's miserable record when it comes to foreign languages, “Linguists call America 'the graveyard of languages' because of its singular ability to take in millions of immigrants and make their native languages die out in a few generations,” Collins writes. Educated in Wilmington, N.C., and at Princeton, she could — like the vast majority of Americans — only speak their mother tongue.

    Eight months after she moved to Switzerland, Collins gives up on the natural acquisition of language and finally attends a French course. As she struggles with grammar and vocabulary, Collins notes smartly that vert (green),verre (glass), ver (worm), vers (toward), and vair (squirrel) compose a quintuple homonym (同形异义). “Although it's difficult, French can try” she says.

    French is actually considered among the easiest languages for an English speaker to learn, especially compared to Arabic or Mandarin Chinese. Collins, whose notably rich English vocabulary includes glossolalia (nonsense speech) and shibboleth (catchword or slogan), finds plenty of terrific French words to love. She writes, “English is a trust fund, an unearned inheritance (遗产), but I've worked for every bit of French I've banked.”

    Unlike Jhumpa Lahiri, who became so hooked on Italian and used it to write In Other Words, Collins's goals for learning French were more modest, “I wanted to speak French and to sound like North Carolina.” She also wanted to be able to deal with chimney sweeps and butchers, communicate with her in-laws, and “to touch Olivier in his own language.” She admits that she feels different speaking French. ''Its austerity (朴素) made me feel more confused.”

    Readers looking for the romantic spark of classic cross-cultural love stories featuring an outgoing American and a shy Frenchman will find flashes of it here. Among the many cultural differences the couple argue over are her enthusiastic American habit of applying the verb love to express enthusiasm for shoes, strawberries, and husbands alike. But there's far more to Collins, book than fantastic comedy, and those who have experienced linguistic crossings themselves tend to find particular resonance (共鸣) in its inquiry into language, identity, and transcultural translation.

Arranged by chapters named for verb tenses, When in French works its way from The Past Perfect (Le plus-que-parfait) to The Present (Le Present) and The Conditional (Le Conditionnel). Collins ends on a delightful note with Le Futur—fitting for a new mother about to move with her hard-won French husband, French language, and Swiss-born daughter to the French-speaking city of her dreams, Paris.

    According to a recent survey on money and relationships, 36% of people are keeping a bank account from their partner. While this financial unfaithfulness may appear as distrust in a relationship, in truth it may just be a form of financial protection.

    With almost half of all marriages ending in divorce, men and women are realizing they need to be financially savvy, regardless of whether they are in a relationship.

    The financial hardship on individuals after a divorce can be extremely difficult, even more so when children are involved. The lack of permanency in relationships, jobs and family life may be the cause of a growing trend to keep a secret bank account hidden from a partner, in other words, an "escape fund".

    Margaret's story is far from unique. She is a representative of a growing number of women in long-term relationships who are becoming protective of their own earnings. Every month on pay day, she banks hundreds of dollars into a savings account she keeps from her husband. She has been doing this throughout their six-year marriage and has built a nest egg worth an incredible $100,000. Margaret says if her husband found about her secret savings he'd be hurt and would take this as a sign that she wasn't sure of the marriage. "He'd think it was my escape fund so that financially I could afford to get out of the relationship if it went wrong. I know you should approach marriage as being forever and I hope ours is, but you can never be sure."

    Like many of her fellow secret savers, Margaret was hurt in a former relationship and has since been very guarded about her own money.

    Coming clean to your partner about being a secret saver may not be all that bad. Take Colleen for example, who had been saving secretly for a few years before she confessed (坦白) to her partner. "I decided to open a savings account and start building a nest egg of my own. I wanted to prove to myself that I could put money in the bank and leave it there for a rainy day."

    By analyzing the fossilized teeth of some of our most ancient ancestors, a team of scientists led by the universities of Bristol (UK) and Lyon (France) have discovered that the first humans significantly breastfed their infants (婴儿) for longer periods than their contemporary relatives.

    The results, published in the journal Science Advances, provide a first insight into the practice of weaning (断奶)that remain otherwise unseen in the fossil record.

    The team sampled minute amounts from nearly 40 fossilized teeth of our South African fossil relatives, early Homo, Paranthropus robustus and Australopithecus africanus. They measured the proportions of their stable calcium isotopes (同位素）in the tooth enamel(牙釉质), which are a function of the mother milk intake by infants. They show that early Homo offspring(后代) was breastfed in significant proportions until the age of around three to four years, which likely played a role in the apparition of traits that are specific to human lineage(血统), such as the brain development.

    In contrast, infants of Paranthropus robustus, that became extinct around one million years ago and were a more robust species in terms of dental anatomy, as well as infants of Australopithecus africanus, stopped drinking sizeable proportions of mother milk in the course of the first months of life.

    These differences in nursing behaviors likely come with major changes in the social structures of groups as well as the time between the birth of one child and the birth of the next.

    One of the study's lead authors, Dr Theo Tacail said: "The practice of weaning -- the duration of breastfeeding, age at non-milk food introduction and the age at cessation of suckling -- differs among the modern members of the hominid family which includes humans and modern great apes: orangutan, gorillas, chimpanzees and bonobos.

    The development of such behavioral differences likely played major roles in the evolution of the members of human lineage, being associated for instance with size and structure of social groups, brain development.

    However, getting insights into these behavioral changes from fossils that are millions of years old is a challenge and, so far, little evidence allow discussing nursing practices in these fossil species.

    The findings stress the need for further exploration of calcium stables isotopes compositions in the fossil record in order to understand the co-evolution of weaning practices with other traits such as brain size or social behaviors."
