This post is part of the Friday Q&A section. If you want to ask a question, just write a comment below. Cherran asks:
As a person working online, after the initial revenue goals are achieved, I’m getting a feeling that I’m little bit straying away from the normal world. Even for a small business owner with half of our income, he would need to interact with people face to face everyday.

Climate-change assessment: Must try harder
By admin | September 2, 2010
A call to reform the IPCC
IF THIS week’s report into the workings of the Intergovernmental Panel on Climate Change (IPCC) by a council of national academies of science were the sort of report children take home from school, its main themes would be expressed as “could do better” and “needs to show workings”. Stern parents might read it as calling for a Gradgrind-like clampdown; more indulgent ones as an inducement for the little darlings to try a little harder.
At a meeting in Busan, South Korea, this October, the parents in question—the representatives of the IPCC’s member governments—will decide which sort they want to be. Read in detail, the report suggests that if they want credible climate assessments, a firm hand will be required. …

The future of the internet: A virtual counter-revolution
By admin | September 2, 2010
The internet has been a great unifier of people, companies and online networks. Powerful forces are threatening to balkanise it
THE first internet boom, a decade and a half ago, resembled a religious movement. Omnipresent cyber-gurus, often framed by colourful PowerPoint presentations reminiscent of stained glass, prophesied a digital paradise in which not only would commerce be frictionless and growth exponential, but democracy would be direct and the nation-state would no longer exist. One, John-Perry Barlow, even penned “A Declaration of the Independence of Cyberspace”.
Even though all this sounded Utopian when it was preached, it reflected online reality pretty accurately. The internet was a wide-open space, a new frontier. For the first time, anyone could communicate electronically with anyone else—globally and essentially free of charge. Anyone was able to create a website or an online shop, which could be reached from anywhere in the world using a simple piece of software called a browser, without asking anyone else for permission. The control of information, opinion and commerce by governments—or big companies, for that matter—indeed appeared to be a thing of the past. “You have no sovereignty where we gather,” Mr Barlow wrote. …

The nature of the universe: Ye cannae change the laws of physics
By admin | September 2, 2010
Or can you?
RICHARD FEYNMAN, Nobel laureate and physicist extraordinaire, called it a “magic number” and its value “one of the greatest damn mysteries of physics”. The number he was referring to, which goes by the symbol alpha and the rather more long-winded name of the fine-structure constant, is magic indeed. If it were a mere 4% bigger or smaller than it is, stars would not be able to sustain the nuclear reactions that synthesise carbon and oxygen atoms. One consequence would be that squishy, carbon-based life would not exist.
Why alpha takes on the precise value it does, so delicately fine-tuned for life, is a deep scientific mystery. A new piece of astrophysical research may, however, have uncovered a crucial piece of the puzzle. In a paper just submitted to Physical Review Letters, a team led by John Webb and Julian King from the University of New South Wales in Australia presents evidence that the fine-structure constant may not actually be constant after all. Rather, it seems to vary from place to place within the universe. If their results hold up to scrutiny they will have profound implications—for they suggest that the universe stretches far beyond what telescopes can observe, and that the laws of physics vary within it. Instead of the whole universe being fine-tuned for life, then, humanity finds itself in a corner of space where, Goldilocks-like, the values of the fundamental constants happen to be just right for it. …

Technology and protest: A town crier in the global village
By admin | September 2, 2010
A cross-border fraternity that strives to be seen, heard and heeded
NEARLY four years ago, a web-based political movement set itself the modest task of “closing the gap between the world we have and world most people everywhere want”. Calling their group Avaaz, which means “voice” in several languages, the founders aimed to reproduce globally some of the success which their progenitors—like America’s Moveon.org, and Australia’s Getup!—had enjoyed in national political arenas.
By its own lights, the movement, using 14 languages and engaged in a mind-boggling list of causes, has had some spectacular successes. Within the next few months, membership will top 6m. The number of individual actions taken (from bombarding a politician with a well-aimed message, or funding a poster campaign, to helping provide satellite phones to Burmese monks) is estimated at over 23m. Among the recent developments Avaaz claims to have influenced are a new anti-corruption law in Brazil; a move by Britain to create a marine-conservation zone in the Indian Ocean; and the spiking of a proposal to allow more hunting of whales. …

Mental stimulation and dementia: Brain gain

Stimulating the brain delays, but does not prevent, dementia
AS THE baby-boomer generation contemplates the prospect of the Zimmer frame there has never been more interest in delaying the process of ageing. One consequence has been a dramatic rise in the popularity of brain-training games. But how effective really is a daily dose of cryptic crossword?
Robert Wilson, a neuropsychologist at Rush University in Chicago, and his colleagues decided to find out, by following a group of people without dementia. Participants were asked to rate how frequently they engaged in cognitively stimulating activities. The researchers were looking for such things as reading newspapers, books and magazines, playing challenging games like chess, listening to the radio and watching television, and visiting museums. …

Mobile internet in emerging markets: The next billion geeks
By admin | September 2, 2010
How the mobile internet will transform the BRICI countries
BUYING a mobile phone was the wisest $20 Ranvir Singh ever spent. Mr Singh, a farmer in the north Indian state of Uttar Pradesh, used to make appointments in person, in advance, to deliver fresh buffalo milk to his 40-odd neighbours. Now his customers just call when they want some. Mr Singh’s income has risen by 25%, to 7,000 rupees ($149) a month. And he hears rumours of an even more bountiful technology. He has heard that “something on mobile phones” can tell him the current market price of his wheat. Mr Singh does not know that that “something” is the internet, because, like most Indians, he has never seen or used it. But the phone in his calloused hand hints at how hundreds of millions of people in emerging markets—perhaps even billions—will one day log on.
Only 81m Indians (7% of the population) regularly use the internet. But brutal price wars mean that 507m own mobile phones. Calls cost as little as $0.006 per minute. Indian operators such as Bharti Airtel and Reliance Communications sign up 20m new subscribers a month. …

Schumpeter: Declining by degree

Will America’s universities go the way of its car companies?
FIFTY years ago, in the glorious age of three-martini lunches and all-smoking offices, America’s car companies were universally admired. Everybody wanted to know the secrets of their success. How did they churn out dazzling new models every year? How did they manage so many people so successfully (General Motors was then the biggest private-sector employer in the world)? And how did they keep their customers so happy?
Today the world is equally in awe of American universities. They dominate global rankings: on the Shanghai Ranking Consultancy’s list of the world’s best universities, 17 of the top 20 are American, and 35 of the top 50. They employ 70% of living Nobel prizewinners in science and economics and produce a disproportionate share of the world’s most-cited articles in academic journals. Everyone wants to know their secret recipe. …

Emerging infections: No good deed goes unpunished
By admin | September 2, 2010
Smallpox has gone, but monkeypox is now rearing its ugly head
ONE of the greatest public-health victories of the last century was the eradication of smallpox. After the disease was pronounced extinct, in 1980, people stopped using the smallpox vaccine. That seemed the ultimate symbol of technology’s triumph over a medieval scourge.
Alas, it turns out that the end of vaccination has unleashed new demons. Researchers have long suspected that smallpox vaccine also provides protection against diseases such as monkeypox and cowpox, and three decades ago a committee of experts weighed up whether ending vaccination for smallpox might allow one of those diseases to spread in humans. They decided this was unlikely. Now, a study published in the Proceedings of the National Academy of Sciences suggests they may have been wrong. A team led by Anne Rimoin of the University of California, Los Angeles, conducted surveys of people living in the centre of the Democratic Republic of Congo. They found a dramatic surge in monkeypox—a disease which, though not as bad as smallpox, kills up to 10% of those it infects. …
