Teenage Brains

Teenage Brains
Although you know your teenager takes some chances, it can be a shock to hear about them. One fine May morning not long ago my oldest son, 17 at the time, phoned to tell me that he had just spent a couple hours at the state police barracks. Apparently he had been driving "a little fast." What, I asked, was "a little fast"? Turns out this product of my genes and loving care, the boy-man I had swaddled, coddled, cooed at, and then pushed and pulled to the brink of manhood, had been flying down the highway at 113 miles an hour. "That's more than a little fast," I said. He agreed. He did, however, object to one thing. "Well," I huffed, sensing an opportunity to finally yell at him, "what would you call it?" "It's just not accurate," he said calmly. " 'Reckless' sounds like you're not paying attention. "I guess that's what I want you to know. Actually, it did make me feel better. Through the ages, most answers have cited dark forces that uniquely affect the teen.

Lab-grown meat is first step to artificial hamburger 19 February 2012Last updated at 15:29 ET By Pallab Ghosh Science correspondent, BBC News, Vancouver The first strips of muscle have been grown in a project to develop a new way to produce meat Dutch scientists have used stem cells to create strips of muscle tissue with the aim of producing the first lab-grown hamburger later this year. Has Science Found a Way to End All Wars? Fry has also identified 74 “nonwarring cultures” that—while only a fraction of all known societies—nonetheless contradict the depiction of war as universal. His list includes nomadic hunter-gatherers such as the !Kung in Africa and Aborigines in Australia. These examples are crucial, Fry says, because our ancestors are thought to have lived as nomadic hunter-gatherers from the emergence of the Homo lineage just over 2 million years ago in Africa until the appearance of agriculture and permanent settlements about 12,000 years ago.

Chapter 9: Limbic System The limbic system is a convenient way of describing several functionally and anatomically interconnected nuclei and cortical structures that are located in the telencephalon and diencephalon. These nuclei serve several functions, however most have to do with control of functions necessary for self preservation and species preservation. They regulate autonomic and endocrine function, particularly in response to emotional stimuli. They set the level of arousal and are involved in motivation and reinforcing behaviors. Additionally, many of these areas are critical to particular types of memory. Some of these regions are closely connected to the olfactory system, since this system is critical to survival of many species.

McCann on Millennials, Social Media, and Brands Call them the FB generation. McCann Worldgroup’s newly completed global survey “The Truth About Youth,” which polled 16-to-30-year-olds, concludes that millennials live in a new “social economy” in which the power of sharing and recommending brands cannot be overstated. (Past generations defined themselves by material possessions or experiences.) This group, according to the study, lives outloud, emphasizing public self-definition, life narration, and broadcasting via blogging platforms, digital cameras, and cheap editing and design software. In the words of one study respondent: “If there are no pics, it didn’t happen.”

Secrets of the shopping trolley A survey found that when they cook, more than half of all Australians rotate between a repertoire of five meals or fewer. Photo: Peter Braig YEAH, yeah, I know - two serves of fruit and six serves of veg; three serves of lean meat and six (six!) serves of grains. Two-and-a-half of dairy; and beer, vodka and triple-choc mud cake ''only sometimes and in small amounts''.

The Future isn’t What it Used to Be “The trouble with our times is that the future is not what it used to be.” — Paul Valery (French Poet, Essayist and Critic, 1871-1945) “Innumerable confusions and a feeling of despair invariably emerge in periods of great technological and cultural transition.” Marshall McLuhan (philosopher , futurist , and communications theorist, 1911-1980) A current futurist, Ray Kurzweil, adds another dimension to this chicken little tale. In his book The Singularity is Near he makes some stunning predictions about the impact of technology in the next century. Sci-fi, artificial intelligence and utopian vision aside, one chapter read 9 months ago has infected my work in ways I haven’t experienced since my first encounters with McLuan.

Human Physiology - Neurons & the Nervous System The human nervous system consists of billions of nerve cells (or neurons)plus supporting (neuroglial) cells. Neurons are able to respond to stimuli (such as touch, sound, light, and so on), conduct impulses, and communicate with each other (and with other types of cells like muscle cells). Nervous system The nucleus of a neuron is located in the cell body. What Makes Millennials Happy? As if life weren't complicated enough in an era of technological and economic flux, today's 18-25-year-olds must also cope with unpredictable shifts in gender roles. It's one aspect of the culture wars in which no one is granted the safety of non-combatant status. However, a newly released survey of millennial-generation adults by Euro RSCG makes it clear that the tensions don't reliably play out the way you might guess. And the attitudes of young-adult women differ significantly from those in evidence a couple decades ago amid a more us-against-them phase of feminism. The survey finds female respondents (and many of their male counterparts) taking it as a non-negotiable given that women's role as the "second sex" is a thing of the past.

Soft Drinks Linked To Eye Damage In Children Accurate indication ... "It is definitely a warning to parents and children to cut down on carbohydrates and sugar".
