Programmable brain cells

  Pluripotent stem cell research took off like a rocket 

in 2012. After discovering that skin cells can be 

genetically reprogrammed into stem cells, which can in 

turn be reprogrammed into just about any cell in the 

[5] human body, a team led by Sheng Ding at UCSF 

managed to engineer a working network of newborn 

neurons from a harvest of old skin cells. In other words, 

the team didn’t just convert skin cells into stem cells, 

then into neurons — they actually kept the batch of 

[10] neurons alive and functional long enough to self-organize 

into a primitive neural network. In the near future, it’s 

likely that we’ll be treating many kinds of brain injuries 

by growing brand-new neurons from other kinds of cells 

in a patient’s own body. This is already close on the 

[15] horizon for liver and heart cells — but the thought of 

being able to technologically shape the re-growth of a 

damaged brain is even more exciting.

Considering language use in the text, it’s correct to say:

T E X T  

  Language is forever changing – and forms such as tweets and text messages are no less valid than any textbook version, says the linguist David Crystal, whose latest book encourages children to engage with the possibilities of their lingua franca.

  Were the English language ever to need an official guardian, Professor David Crystal certainly looks the part. But the professor would, I suspect, quickly shrug off such a custodial title – not out of modesty, but principle. Though many endangered languages need their champions, he would say, English does not require a guardian; it is vibrant and evolving and can fend for itself. 

  Crystal’s A Little Book of Language is the latest work of a prolific career. He already has more than 100 books to his name; some are academic but many are for the general inquisitive reader, including By Hook or by Crook: A Journey in Search of English and Shakespeare's Words, which was co-authored by his son, Ben.

  For the Crystals, linguistics is clearly a family affair. In the jaunty early chapters of A Little Book of Language, Crystal notes how, when his four children were young, he would study them."We're talking the 1960s, when the study of linguistics had hardly begun – people did not know, in a scientific way, how you developed language," he recalls. "Several of us linguists at that time would record our own kids, just to get some data. There was some literature on it then, but no day-by-day, blow-by-blow examples. I recorded all my children over the years in some shape or form. It's what linguists do. You don't talk to a linguist without having what you say taken down and used in evidence against you at some point in time." 

  Something must have rubbed off. Though his elder two children, Steven and Sue, eschewed academia, his daughter Lucy took up copywriting and his son Ben, an actor, is now following his father. "His book Shakespeare on Toast was a runaway hit – I wish I'd written it!" says Crystal, before rapidly, and self-effacingly, adding: "But I couldn't have – because it was so cool and modern and so street in its approach to Shakespeare. He has examples of hip-hop Shakespearians and I would never have dared put any of that stuff into one of my books." 

  A Little Book of Language is a simple history of all language, taking in phonetics, development, social uses, the internet, endangered languages and a touch of literature.

  This all sounds very innocent, but books for children can be a contentious issue. Language, as much as history, is part of a national identity and cannot escape contemporary debates. And since Crystal began his academic career in the early 1960s, there have been dramatic shifts in how the English language is taught. "The ethos of 50 years ago was that there was one kind of English that was right and everything else was wrong; one kind of access that was right and everything else was inferior," he says. "Then nobody touched language for two generations. When it gradually came back in, we didn't want to go back to what we did in the 1950s. There's a new kind of ethos now." 

  What has replaced it is something far more fluid – descriptive rather than prescriptive, as the terminology goes. In schools, appropriateness has replaced the principle of correctness. "Now, one looks at all varieties of language and asks why they are used, says Crystal. "We are rearing a generation of kids who are more equitable and more understanding about the existence of language variety and why it is there." 

  This doesn't sit easy with the traditionalists, of whom there are still many. His clearest example is the belief that text messaging is destroying children's ability to spell. "It's all nonsense, but people believe it." 

  He addressed this in his book Txtng: the Gr8 Db8, published three years ago, in which he found that "txt speak" accounted for barely 10 per cent of the contents of the messages exchanged, and noted that abbreviations have always been part of the English language. Having solved that argument with some decent data, he tells me that he's now moving on to Twitter. 

  "On Twitter [which limits each written entry to 140 characters], you don't get the range of texting abbreviations you get in text messaging. It's a more sophisticated kind of communicative medium. You get semantic threads running through it. When you start counting thousands and thousands of messages, you suddenly realise that on the whole it's a new art form in the making." 

  The breadth of the internet means that language is morphing not just on grocers' signs and in school playgrounds, but on a far more fundamental level. 

  "All these different genres – instant messaging, blogging, chatrooms, virtual worlds – have evolved different sets of communicative strategies, which means that you can look at the language and say, 'That must be an example of a chatroom, that must be an example of a tweet,' and you can predict it." 

  Becoming involved in bigger arguments seems to be an occupational hazard for a linguist. Whether it be education, politics or neuroscience, we all have a vested interest in the implications of language. Our conversation turns to the recent news of a man who had been lying in a vegetative state for seven years before doctors managed to establish basic communication by scanning his brainwaves. "We are moving fast in a direction where you will be able to see what people are saying," says Crystal, optimistically. "We've got to the stage where you can see the complexity of language processing. We're not at the stage yet of being able to see clearly individual sentence patterns and words, but it's not long off." 

  Surely this has huge implications, not least for personal liberties? "It is the case that virtually every language issue resolves into a social or political or psychological issue," Crystal reminds me. "Language has no independent existence apart from the people who use it. It is not an end in itself; it is a means to an end of understanding who you are and what society is like. At which point, you know that a linguist has to bow out and say, 'This is bigger than me.'"
