This article outlines who and what trolls are, and what they do. It also shows some extreme examples of trolls, and how language can be abused and used as a weapon.

"One promising answer comes from the computer scientist Jon Postel, now known as "god of the Internet" for the influence he exercised over the emerging network. In 1981, he formulated what's known as Postel's Law: "Be conservative in what you do; be liberal in what you accept from others." Originally intended to foster "interoperability," the ability of multiple computer systems to understand one another, Postel's Law is now recognized as having wider applications. To build a robust global network with no central authority, engineers were encouraged to write code that could "speak" as clearly as possible yet "listen" to the widest possible range of other speakers, including those who do not conform perfectly to the rules of the road. The human equivalent of this robustness is a combination of eloquence and tolerance - the spirit of good conversation. Trolls embody the opposite principle. They are liberal in what they do and conservative in what they construe as acceptable behavior from others. You, the troll says, are not worthy of my understanding; I, therefore, will do everything I can to confound you."

This article talks about how even though learning how to program a computer seems like learning a new language, computer language is actually processed through a different area of the brain than when language is processed. It says that it activates the multiple demand network, which is also activated by complex cognitive tasks such as solving math problems or crossword puzzles. However, it appears to rely on different parts of the network than math or logic problems do, which suggests that coding does not precisely replicate the cognitive demands of mathematics either. The article says that researchers didn't find any regions that appear to be exclusively devoted to programming. They also suggest that understanding computer code cannot be categorized as a language-based or math-based skill. Instead, they think it might require a combination of both skills, even though the brain regions don't reflect it.

Adopting the same gestures, posture or tone can enhance bonding and help with networking or negotiating. mirroring can help you create powerful connections with others. This behavior, often called "the chameleon effect," often causes others to like and trust you more. Professional networkers, negotiators and salespeople say they use mirroring to help them engage more deeply in a conversation and understand the person they're talking with. Retail salespeople who were told to mimic the nonverbal and verbal behavior of customers sold more products and left customers with a more positive opinion of the store, according to a 2011 study of 129 customers by French researchers. In another study, published in 2008 in the Journal of Experimental Social Psychology, 62 students were assigned to negotiate with other students. Those who mirrored others' posture and speech reached a settlement 67% of the time, while those who didn't reached a settlement 12.5% of the time.

This article talks about how texting can affect a teenager's brain

Two graduate economics students from Washington State University used Twitter to analyze how sports pundits' reputation was affected by their confidence and accuracy at predicting the outcomes to sporting events. They analysed tweets in which professional pundits and fans made predictions about the winners of a series of high-profile baseball and American Football matches. Each tweet was given a "confidence" rating depending on its language, with words like "destroy" and "annihilate" scoring higher than "beat", for example. Both the pundits and fans' predictions were worse than chance, with the professional analysts only proving correct 47 per cent of the time and amateurs 45 per cent of the time. Yet pundits' confidence was measured as 50 per cent higher than amateurs, and they gained more followers on the networking website as a result, the researchers said. Presenting their findings at the Annual Meeting of the Academy of Economics and Finance earlier this year, the researchers explained that being confident could increase a pundit's following by 17 per cent, while predicting every game correctly only raised it by 3.4 per cent.There was a similar pattern among amateurs, with brash people increasing their following by 20 per cent but correct guesses only raising it by 7.3 per cent. In general, pundits are better served by being brash and making people excited, they claimed.

Santiago Swallow is "a Mexican-born, American motivational speaker, consultant, educator, and author, whose speeches and publications focus on understanding modern culture in the age of social networking, globally interconnected media, user generated content and the Internet," and has "dedicated himself to helping others know more about how media and personality can manipulated in the 21st Century." Though completely fictional, he boasts a Wikipedia biography and a Twitter account with tens of thousands of followers. Making up-or at least "enhancing"-an identity like this is something real people do to increase their reputation, look popular, and sell themselves. There are equally real people who profit from this by selling fake followers created by software at the push of a button. Be afraid.

Twitter - the social network where users write tweets of 140 characters is changing how poets and novelists write. They are being forced to strip down language to its bare minimum.

Bradley Hayes, a post-doc student at the Massachusetts Institute of Technology, has invented @DeepDrumpf, an amusing bit of artificial intelligence. DeepDrumpf is a bot trained on the publicly available speech transcripts, tweets, and debate remarks of Donald Trump. Using a machine learning model known as a Recurrent Neural Network, the bot generates sequences of words based on priming text and the statistical structure found within its training data. Created to highlight the absurdity of this election cycle, it has amassed over 20,000 followers and has been viewed over 12 million times -- showcasing the consequences of training a machine learning model on a dataset that embodies fearmongering, bigotry, xenophobia, and hypernationalism. Here's a sample tweet: "We have to end education. What they do is unbelievable, how bad. Nobody can do that like me. Believe me."

Two University of Washington undergraduates have won a $10,000 Lemelson-MIT Student Prize for gloves that can translate sign language into text or speech. The Lemelson-MIT Student Prize is a nationwide search for the most inventive undergraduate and graduate students. This year, UW sophomores Navid Azodi and Thomas Pryor - who are studying business administration and aeronautics and astronautics engineering, respectively - won the "Use It" undergraduate category that recognizes technology-based inventions to improve consumer devices. Their invention, "SignAloud," is a pair of gloves that can recognize hand gestures that correspond to words and phrases in American Sign Language. Each glove contains sensors that record hand position and movement and send data wirelessly via Bluetooth to a central computer. The computer looks at the gesture data through various sequential statistical regressions, similar to a neural network. If the data match a gesture, then the associated word or phrase is spoken through a speaker.

With the spread of mobile technology, it's become much easier for more people to maintain constant contact with their social networks online. And a lot of people are taking advantage of that opportunity. One indication: A recent Pew Research survey of adults in the U.S.

Is social media good for you, or bad? Well, it's complicated. A UC San Diego study of 12 million Facebook users suggests that using Facebook is associated with living longer -- when it serves to maintain and enhance your real-world social ties. Those on Facebook with highest levels of offline social integration -- as measured by posting more photos, which suggests face-to-face social activity -- have the greatest longevity. Online-only social interactions, like writing wall posts and messages, showed a nonlinear relationship: Moderate levels were associated with the lowest mortality. Facebook users who accepted the most friendships also lived longest.

What can you recite by heart? Your times tables? German verb formations? The Lord's Prayer? Novelist Salman Rushdie thinks it should be poetry. Speaking at the Hay Festival, the writer described memorising poems as a "lost art" that "enriches your relationship with language". David Whitley, a lecturer at Cambridge University, Whitely, whose Poetry and Memory project surveyed almost 500 people, says: "Those who memorised poems had a more personal relationship [with the poem] - they loved it for the sound and meaning, but it also connected with their life currents - people they loved, or a time that was important to them. "For people who memorise a poem, it becomes a living thing that they connect with - more so than when it is on a page. Learning by heart is often positioned as the opposite of analysis. But for many people who know a number of poems, their understanding grows over time and changes." Psychotherapist Philippa Perry agrees. She points out that memorising anything, from poems to music, means you always have it with you. She thinks that memorising poems can also be good for the health of our brains. "The way we 'grow' our brains is that we make connections between our brain cells - neural pathways. The more you exercise that network, the more you strengthen it. If you learn things by heart, you get better at it."

There are ways to reduce your risk of having a stroke - for example, you can exercise more and not smoke. But should a stroke occur, you might also be able to reduce your risk of losing brain function if you are a speaker of more than one language.

Dr. Thomas Bak, one of the study's authors, posits that language learning helps brains build "cognitive reserve": a rich network of neural connections - highways that can can still carry the busy traffic of thoughts even if a few bridges are destroyed, as via a stroke. "People with more mental activities have more interconnected brains, which are able to deal better with potential damage," Bak says. He likens language learning's effect on the brain to swimming's ability to strengthen the body. Learning a language at any stage in life provides a thorough workout, but other cognitive "exercises," such as doing puzzles or playing a musical instrument, might also benefit stroke recovery, he said. The research applies to the larger concept of neuroplasticity, in that the brain is dynamic and can adapt to new challenges when properly conditioned,

"Experienced meditators seem to be able switch off areas of the brain associated with daydreaming as well as psychiatric disorders such as autism and schizophrenia ... Less day dreaming has been associated with increased happiness levels ... experienced meditators had decreased activity in areas of the brain called the default mode network, which has been implicated in lapses of attention and disorders such as anxiety, attention deficit and hyperactivity disorder, and even the buildup of beta amyloid plaques in Alzheimer's disease."

"Two scholars of the 17th and 18th centuries say the earlier era prefigured the "information overload," with its own equivalents of Twitter, Facebook and Google+. Social networks have been key to almost all revolutions - from 1789 to the Arab Spring." Also includes an short, interesting video interview with the researchers.

Research by the University of Liverpool has found that the same brain activity is used for language production and making complex tools, supporting the theory that they evolved at the same time. Dr Georg Meyer, from the University Department of Experimental Psychology, said: "This is the first study of the brain to compare complex stone tool-making directly with language. "Our study found correlated blood-flow patterns in the first 10 seconds of undertaking both tasks. This suggests that both tasks depend on common brain areas and is consistent with theories that tool-use and language co-evolved and share common processing networks in the brain."

Fascinating article on language learning using an app called Memrise. The company's goal: to take all of cognitive science's knowhow about what makes information memorable, and combine it with all the knowhow from social gaming about what makes an activity fun and addictive, and develop a web app that can help anyone memorise anything. Two takeaways for language learning, and acquiring and retaining any subject matter: 1. Elaborative encoding. The more context and meaning you can attach to a piece of information, the likelier it is that you'll be able to fish it out of your memory at some point in the future. And the more effort you put into creating the memory, the more durable it will be. One of the best ways to elaborate a memory is to try visually to imagine it in your mind's eye. If you can link the sound of a word to a picture representing its meaning, it'll be far more memorable than simply learning the word by rote. Create mnemonics for vocabulary. 2. "Spaced repetition". Cognitive scientists have known for more than a century that the best way to secure memories for the long term is to impart them in repeated sessions, distributed across time, with other material interleaved in between. If you want to make information stick, it's best to learn it, go away from it for a while, come back to it later, leave it behind again, and once again return to it - to engage with it deeply across time. Our memories naturally degrade, but each time you return to a memory, you reactivate its neural network and help to lock it in. One study found that students studying foreign language vocabulary can get just as good long-term retention from having learning sessions spaced out every two months as from having twice as many learning sessions spaced every two weeks. To put that another way: you can learn the same material in half the total time if you don't try to cram.

"I described my "Perjury" problem - I was interested in the subject and engrossed in the book for days, but now remember nothing about it - and asked her if reading it had ultimately had any effect on me. "I totally believe that you are a different person for having read that book," Wolf replied. "I say that as a neuroscientist and an old literature major." She went on to describe how reading creates pathways in the brain, strengthening different mental processes. Then she talked about content. "There is a difference," she said, "between immediate recall of facts and an ability to recall a gestalt of knowledge. We can't retrieve the specifics, but to adapt a phrase of William James's, there is a wraith of memory. The information you get from a book is stored in networks. We have an extraordinary capacity for storage, and much more is there than you realize. It is in some way working on you even though you aren't thinking about it.""

Love it! People keep mentioning "Proust and the Squid" to me, and it's high time I read it.
