Do we really give introverts a hard time?

It is often assumed extroverts do best in life, but according to a new best-selling book, introverts are just as high achievers. It claims there is a bias towards extroverts in Western society. So do we discriminate against introverts?

Barack Obama, JK Rowling and Steve Wozniak.

They might not immediately stand out as introverts, but according to Susan Cain, American author of Quiet: The Power of Introverts In a World That Can't Stop Talking, they are.

That is because she says, contrary to popular opinion, introverts are not necessarily shy or anti-social, they just prefer environments that are not over-stimulating and get their energy from quiet time and reflection.

Conversely, extroverts need to be around other people to recharge their batteries.

'Social-Media Blasphemy' Texas researcher adds 'Enemy' feature to Facebook

Dean Terry has 400 friends on Facebook, but he wants some virtual enemies.

Mr. Terry, who is director of the emerging-media program at the University of Texas at Dallas, says a major flaw of the popular social network is that it's all sunshine and no rain: The service encourages users to press the "like" button, but offers no way to signal which ideas, products, or people they disagree with. And "friend" is about the only kind of connection you can declare.

Real-world relationships are more complicated than that, so social networks should be too, the scholar argues. He's not alone—more than three million people have voted for a "dislike" feature on an online petition on Facebook.

But Mr. Terry has decided to take action, protesting the ethos of Facebook by literally rewiring the service. Or at least, adding the ability to declare "enemies."

"It's social-media blasphemy, in that we're suggesting that you share differences you have with people and share things that you don't like instead of what you do like," he told me last week. "I think social media needs some disruption. It needs its shot of Johnny Rotten.

Will we ever grow replacement hands?

It might seem unbelievable, but researchers can grow organs in the laboratory. There are patients walking around with body parts which have been designed and built by doctors out of a patient's own cells.

Over the past few weeks on the BBC News website we have looked at the potential for bionic body parts and artificial organs to repair the human body. Now we take a look at "growing-your-own".

Why Community-College Students Need Great Books

No president in recent memory seems to have paid as much attention to community colleges as Barack Obama has.

In his 2013 budget proposal, the president allocated $8-billion for partnerships between states and community colleges to train an estimated two million workers in high-growth and high-demand job areas. And last fall, the U.S. Departments of Labor and of Education paid out to community colleges the first $500-million installment of a $2-billion plan to improve career-development programs and train dislocated workers or those with obsolete skills.

This is good news for community colleges, especially during tough economic times when state financing is down, budgets are being cut, and enrollments have begun to decline after several years of steady growth. The Obama administration is not just sending the message that community colleges should be the job-skills training centers of the 21st century; it is giving them the money to fulfill this function.

Why I Am Leaving Goldman Sachs

By Greg Smith
TODAY is my last day at Goldman Sachs. After almost 12 years at the firm — first as a summer intern while at Stanford, then in New York for 10 years, and now in London — I believe I have worked here long enough to understand the trajectory of its culture, its people and its identity. And I can honestly say that the environment now is as toxic and destructive as I have ever seen it.

Meaning of 'literally' shrinking away

Inappropriate use of the word "literally" has become so commonplace it is now "epidemic", a leading author said yesterday.
Nick Clegg, the Deputy Prime Minister, incorrectly used the word to describe high earners when he said in an interview with the Daily Telegraph: "You see people literally in a different galaxy who are paying extraordinarily low rates of tax."

Writer and comedian Paul Parry was scathing about the Deputy Prime Minister's slip. He told Today: "This is probably the worst thing Nick Clegg has ever done. He's just completely misusing the word."

He added: "It's not about pedantry, it's about communication. The key thing is the word 'literally' is a safe word.

Encyclopaedia Britannica ends its famous print edition

After 244 years reference book firm Encyclopaedia Britannica has decided to stop publishing its famous and weighty 32-volume print edition.

It will now focus on digital expansion amid rising competition from websites such as Wikipedia.  The firm, which used to sell its encyclopaedias door-to-door, now generates almost 85% its revenue from online sales.
It recently launched a digital version of its encyclopaedias for tablet PCs."The sales of printed encyclopaedias have been negligible for several years," said Jorge Cauz president of Encyclopaedia Britannica.
"We knew this was going to come."

Can Interviewers Insist on ‘Shoulder Surfing’ Your Facebook Page?

Privacy advocates say that, for now, it is legal for a prospective employer, during a job interview, to insist that you log into your Facebook page and then click through your “friends only” posts, photos and messages.
The ACLU put a stop to companies demanding that applicants turn over their login and password credentials, but “shoulder surfing,” as it’s been dubbed, is legal for the time being. Aleecia M. McDonald, a privacy researcher and resident Fellow at the Stanford Center for Internet and Society, says high unemployment makes it hard to stamp out this practice. “When you have a job market where there are more job seekers than hirers, you’re going to see things like demanding to see your Facebook wall because if you say no, someone else is waiting for that interview.”

Are Google Glasses the Beginning of the End of Gadgets?

In late February, the New York Times reported that Google will release its Android-powered, heads up display Google Glasses before the end of 2012. Different stories exist around the functionality and look of Google Glasses, being built in the secretive GoogleX offices. But thanks to observations from people like 9 to 5 Google blogger Seth Weintraub and the New York Times’ Nick Bilton, we think they’ll have these characteristics:
  • Small camera providing real-time data about a person’s environment (also takes pictures)
  • Head tilting-driven navigation system
  • Non-transparent heads up display on one lens
  • Voice input and output capabilities
  • The downside? Google Glasses are rumored to look more like “terminator glasses” than everyday eyewear.
Why are Google Glasses a big deal? Because they may be the beginning of the end of gadgets.

Paris Fashion Week: Vivienne Westwood Gold Label autumn/winter 2012

From Edwardian coats to Elizabethan corsets via leggings and dresses printed with mish-mashed Union Flag print, Vivienne Westwood's collection semaphored Britishness.


Dame Vivienne Westwood made her ceremonial progress - complete with regal waves to the watching crowd - wearing a semi-sheer dress printed with out-of-issue British £50 notes. The Dame was wearing The Queen.

Can you build a human body?

  • Technology has always strived to match the incredible sophistication of the human body. Now electronics and hi-tech materials are replacing whole limbs and organs in a merger of machine and man.
    Later this year a team of researchers will try out the first bionic eye implant in the UK hoping to help a blind patient see for the first time. It is one of the extraordinary medical breakthroughs in the field, which are extending life by years and providing near-natural movement for those who have lost limbs.
    Over the coming weeks, BBC News will explore the field of bionics in a series of features. We start with a selection of the latest scientific developments.

Can three minutes of exercise a week help make you fit?

A few relatively short bursts of intense exercise, amounting to only a few minutes a week, can deliver many of the health and fitness benefits of hours of conventional exercise, according to new research, says Dr Michael Mosley. But how much benefit you get from either may well depend on your genes. 

Warning: meetings may be bad for your IQ

We all know that meetings don't make you more intelligent, but new findings suggest they may make you stupid, at least temporarily. Research from the Virginia Tech Crilion Research Institute showed that subjects performed less well on IQ tests directly after spending time in small social groups than they did when they were alone, and even worse when their performance was publicly ranked among their peers. As one of the researchers put it: "Our study highlights the unexpected and dramatic consequences even subtle social signals in group settings may have on individual cognitive functioning."

Tablets Will Take Over Sooner Than You Think: Five Telling Trends

On an earning conference call in January, Apple CEO Tim Cook said, “I truly believe, and many others in the company believe, that there will come a day that the tablet market in units is larger than the PC market.” (See full transcript at Seeking Alpha) “Question is when?” asked  on the Asymco blog. What follows was his detailed projection, with lots of yummy looking charts, that came to the conclusion, “Given these assumptions, the day when the tablet market (by units) will exceed that of traditional PCs will come sometime in the fall of 2013.”

Funniest exam answers become internet sensation

Teachers from the US and UK are posting the best real exam answers from the pupils they teach on the website http://funnyexam.com
The students may have got an E in their tests but they've been creating chortles on the internet since the site was created.
Many of the answers range from the disturbing to the crude and the naive to the ridiculous. There are hundreds to choose from. Some of the funniest are in a slideshow above.
Funny and rude drawings, intentional or not, feature regularly on the site, as do lines directed to teacher, such as "I know I'm going to fail this" or a drawing of a snoring pupil.

Neurohacks | 28 February 2012 Why do we need to sleep?

Some people need eight hours. Others can exist on four. But the bottom line is that everybody needs sleep - it is as essential as breathing and eating. Yet, despite decades of study, scientists still do not know why we do it.
However, there are some intriguing clues and theories. One obvious clue is that we all feel better after a good night’s sleep, and much worse if deprived of a decent night’s rest. In humans the need for sleep gets so strong after a few days that nothing will keep you awake – with reports of people falling asleep standing up, even whilst being kicked or having intolerably loud music played at them. Within days of having no sleep, people report confusion, forgetfulness and hallucinations. (In case you are wondering, the world record for going without sleep is eleven days.)
But saying that we sleep because we are tired is rather like saying we eat because we are hungry – it is why we sleep, but not necessarily why we need it.

Here come the megabuses



China is a country of extremes. The world’s most populous nation; the world’s fastest-growing major economy, the world’s biggest exporter.  It has the world’s longest sea bridge, the world’s fastest train and is the world’s biggest market for cars. The list goes on and on. And its record breaking ways look like they are set to continue for a while yet.
Take that last point. In the mid 80s the country only produced a few thousand cars and hardly anyone actually owned one. Now, it is the world’s largest producer of cars and the world’s largest consumer. Last year, 18 million vehicles were sold, dwarfing the 12.7 million sold in the US. And this sudden explosion has meant a massive rise in one thing: traffic.
However, the ever expanding urban population needs to keep moving and so the government has turned to another extreme solution: the mega bus.
“China is generally looking very hard at new public transport systems” says John Austin, an independent public transport who has worked in Europe, Australia, Singapore, and Hong Kong.  The advantage of buses, he says, is that they can be quick – and cheap – to install, compared to other transport systems, like light railways.

Adventure travel in the age of the online connection



Some of the most remote places in the world are starting to feel less isolated thanks to new technology. This may be good for people who live in them, but for travellers it's a mixed blessing.
Playa Nancite in the Santa Rosa National Park is a bit different this year. It is still one of Costa Rica's most remote spots but it no longer has the same sense of isolation.
The change is certainly not obvious.
Getting here requires the same effort - an hour's drive along a deeply rutted and muddy track, only passable in a four-wheel-drive with a winch, followed by a 40-minute hike over a very steep hill.
The beach itself is also unchanged.
Olive ridley turtles still nest here in their thousands, undisturbed by poachers but hunted by jaguars, which often patrol the beaches at night.
Sadly, there is also little difference to the huge quantity of plastic strewn across the high-tide mark, which washes up on to the golden sands from distant South Pacific islands. 

US spending on pets 'passes $50bn'

Americans are spending more on their pets than ever before, according to estimates in a new report.
The American Pet Products Association (APPA) says spending on pets in the US passed $50bn (£31.5bn) in 2011.
Food and veterinary costs accounted for about 65% of the figure, but the category of "pet services" grew faster than any other, totalling $3.79bn (£2.39bn) in 2011.
Pet services includes grooming, boarding, pet hotels, and pet-sitting.

A Point of View: The language of ties

The decision to wear a tie can be a sartorial minefield for politicians and the public alike, says historian David Cannadine.
The former governor of the state of New York, Mario Cuomo, once observed that in a modern democracy "you campaign in poetry but you govern in prose".
Translated from speech to dress, the attire of Britain's party leaders for the televised debates during the general election of 2010, or of the candidates currently seeking the Republican Party's nomination, or of President Barack Obama when he goes out on the stump, suggests that you campaign wearing an open neck shirt, but govern wearing a tie.

Segmented sleep: Ten strange things people do at night

Most people, when they go to bed, aim to sleep until the morning - but some wake up and are active in the middle of the night.
Last week, we published a story about the myth that an eight-hour sleep is necessary for good health. In response, 10 people told us how they sleep in two separate chunks - and what they do in between.
