The internet: is it changing the way we think? | Technology | The Observer Every 50 years or so, American magazine the Atlantic lobs an intellectual grenade into our culture. In the summer of 1945, for example, it published an essay by the Massachusetts Institute of Technology (MIT) engineer Vannevar Bush entitled "As We May Think". It turned out to be the blueprint for what eventually emerged as the world wide web. Two summers ago, the Atlantic published an essay by Nicholas Carr, one of the blogosphere's most prominent (and thoughtful) contrarians, under the headline "Is Google Making Us Stupid?". "Over the past few years," Carr wrote, "I've had an uncomfortable sense that someone, or something, has been tinkering with my brain, remapping the neural circuitry, reprogramming the memory. My mind isn't going – so far as I can tell – but it's changing. The title of the essay is misleading, because Carr's target was not really the world's leading search engine, but the impact that ubiquitous, always-on networking is having on our cognitive processes.
physiology - What's the maximum and minimum temperature a human can survive? - Biology Stack Exchange Hypothermia (when the body is too cold) is said to occur when the core body temperature of an individual has dropped below 35° celsius. Normal core body temperature is 37°C. (1) Hypothermia is then further subdivided into levels of seriousness (2) (although all can be damaging to health if left for an extended period of time) Mild 35–32 °C: shivering, vasoconstriction, liver failure (which would eventually be fatal) or hypo/hyper-glycemia (problems maintaining healthy blood sugar levels, both of which could eventually be fatal).Moderate 32–28 °C: pronounced shivering, sufficient vasoconstriction to induce shock, cyanosis in extremities & lips (i.e. they turn blue), muscle mis-coordination becomes more apparent.Severe 28–20 °C: this is where your body would start to rapidly give up. Heart rate, respiratory rate and blood pressure fall to dangerous levels (HR of 30bpm would not be uncommon - normally around 70-100). As you mentioned burns, I will go into these too.
The evolutionary reason why rock music excites us: it reminds us of animal distress calls Distorted sounds remind us of animals in distress - which excites our body By Eddie Wrenn Published: 16:40 GMT, 13 June 2012 | Updated: 16:44 GMT, 13 June 2012 Jimi Hendrix playing his guitar during his set at the Woodstock Music and Art Fair in 1969 Ever wonder why Jimi Hendrix's rendition of 'The Star-Spangled Banner' moved so many people in 1969 or why the music in the shower scene of 'Psycho' still sends chills down your spine? A University of California-based team of researchers has isolated some of the ways in which distorted and jarring music is so evocative, and they believe that the mechanisms are closely related to distress calls in animals. They report their findings in the latest issue of the peer-reviewed scientific journal Biology Letters, which publishes online June 12. Blumstein is an authority on animal distress calls, particularly among marmots. They determined that the soundtracks for each genre possessed characteristic emotion-manipulating techniques.
Banishing consciousness: the mystery of anaesthesia - health - 29 November 2011 Read full article Continue reading page |1|2|3 I WALK into the operating theatre feeling vulnerable in a draughty gown and surgical stockings. Two anaesthetists in green scrubs tell me to stash my belongings under the trolley and lie down. "Can we get you something to drink from the bar?" they joke, as one deftly slides a needle into my left hand. I smile weakly and ask for a gin and tonic. I have had two operations under general anaesthetic this year. What they didn't tell me was how the drugs would send me into the realms of oblivion. The development of general anaesthesia has transformed surgery from a horrific ordeal into a gentle slumber. That is starting to change, however, with the development of new techniques for imaging the brain or recording its electrical activity during anaesthesia. Consciousness has long been one of the great mysteries of life, the universe and everything. Lock and key So what do we know about how anaesthetics work? More From New Scientist Brave or reckless?
The Infinity Burial Project Seeking Academic Edge, Teenagers Abuse Stimulants The boy exhaled. Before opening the car door, he recalled recently, he twisted open a capsule of orange powder and arranged it in a neat line on the armrest. He leaned over, closed one nostril and snorted it. Throughout the parking lot, he said, eight of his friends did the same thing. The drug was not cocaine or heroin, but Adderall, an prescribed for that the boy said he and his friends routinely shared to study late into the night, focus during tests and ultimately get the grades worthy of their prestigious high school in an affluent suburb of New York City. “Everyone in school either has a prescription or has a friend who does,” the boy said. At high schools across the United States, pressure over grades and competition for college admissions are encouraging students to abuse prescription stimulants, according to interviews with students, parents and doctors.

Conflict in Fiction June 15, 2011 by Fiction Editor Beth Hill last modified June 15, 2011 A writer and I were recently speaking about conflict. She was trying to add more, to vary the types of conflict in her manuscript, and feeling frustrated. Other than obnoxious arguments and physical fights, what kinds of fictional conflict are there? Simply defined, conflict is a lack of agreement. Simply defined, maybe. There are just too many options and variables for conflict to be simple. There’s no single kind of conflict, no one level, no foolproof approach. And not only are there a number of types or styles, but there are a variety of intensities, levels, of story conflict. The degree of conflict can fall anywhere along a range from absent (or not felt) to overwhelming. Low conflict might arise when a couple can’t decide on what type of food they want for dinner. In a low-level conflict of short duration, there’s little escalation, little discomfort for characters or readers. Characters need disagreements.
Why optimists usually win: Simply thinking positive thoughts can lead people to overcome tough challenges Thinking positively plants a 'suggestion' in the mindCan change behaviour to drive you towards outcome'Suggestion' is much more powerful than thought By Rob Waugh Published: 13:34 GMT, 8 June 2012 | Updated: 13:34 GMT, 8 June 2012 Victory! Thinking positively about something really might make it happen, psychologists say. Simply anticipating something good can gear up hidden circuits in the brain to drive you towards it. Thinking about a happy outcome plants a 'suggestion' in the mind, in a similar way to a hypnotist. Two psychologists at the University of Victoria, New Zeland said: ‘Once we anticipate a specific outcome will occur, our subsequent thoughts and behaviors will actually help to bring that outcome to fruition.’ It can't work magic, obviously, but researchers say effects of suggestion are more powerful than people think and can change behaviours and even outcomes. The expectancies led to automatic responses which can lead to the outcome we were expecting all along.
