Perfectionism can be positive or negative, depending upon whether you’re striving to live up to your own high standards or straining to meet the expectations of others.
Do mobile phones cause cancer?
The International Agency for Research into Cancer (IARC), which is part of the World Health Organisation, convened a panel of 31 experts to look at the available evidence. Their verdict: “radiofrequency electromagnetic fields” – the sort given off by mobile phones – belong to “Group 2B”, which means that they “possibly” cause cancer in humans.
In the first years of the twenty-first century, New York City police officers had six different siren noises at their fingertips to alternate and overdub as they attempted to bore through stagnant traffic. The “Yelp” is a high-pitched, rapidly oscillating, jumpy sound that suggests a small dog with large teeth has hold of your thigh and is not about to let go. The “Wail” is the classic keening noise that the Furies might release while pursuing vengeance. The “Hi-Lo,” or “European,” is whiney, forlorn—prone to depression, but undeniably civilized. The “Air-Horn” is vulgarity incarnate—a burp, a rasp, an all-out bursty blast. The “Fast” or “Priority” resembles a hysteric who’s just mainlined crystal meth. The “Manual” is an outcast loner raising its rifle in a solitary low-to-high pulse.
The summer of 2007 saw the first broaching of the possibility that a seventh instrument might be added to the ensemble.
The Rumbler™.

Why we remember some scenes from early childhood and forget others has long intrigued scientists—as well as parents striving to create happy memories for their kids. One of the biggest mysteries: why most people can’t seem to recall anything before age 3 or 4.
Now, researchers in Canada have demonstrated that some young children can remember events from even before age 2—but those memories are fragile, with many vanishing by about age 10, according to a study in the journal Child Development this month.
The great thing about cities, the thing that is amazing about cities is as they grow, so to speak, their dimensionality increases. That is, the space of opportunity, the space of functions, the space of jobs just continually increases. And the data shows that. If you look at job categories, it continually increases. I’ll use the word “dimensionality.” It opens up. And in fact, one of the great things about cities is that it supports crazy people. You walk down Fifth Avenue, you see crazy people. There are always crazy people. Well, that’s good. Cities are tolerant of extraordinary diversity.
This is in complete contrast to companies. The Google boys in the back garage so to speak with ideas of the search engine, were no doubt promoting all kinds of crazy ideas and maybe having even crazy people around them. Well, Google is a bit of an exception, because it still tolerates some of that. But most companies start out probably with some of that buzz. But the data indicates that at about 50 employees to a hundred that buzz starts to stop. A company that was more multi dimensional, more evolved, becomes uni dimensional. It closes down.
Indeed, if you go to General Motors or you go to American Airlines or you go to Goldman Sachs, you don’t see crazy people.
When we hear about stalkers, we generally think of men. But there are certainly women who stalk [estimated at 6% to 26% of stalkers] and now we have some research to give us information on identifying them. Like their male stalker counterparts, women who make threats are more likely to be violent; women who write letters are less likely to be violent; and women [and men] who stalk their prior sexual intimates are the most likely to be violent.
This research article was based on a large database of stalkers (N=1005) from which a sample of 143 female stalkers was gathered.
Can you imagine getting off a roller coaster ride and falling in love with the first attractive person you see as you leave the ride? Likely not.
But in fact, classic social psychology experiments have shown that sometimes people do misattribute feelings of fear and anxiety to sexual attraction.
More generally, researchers have found that when people feel physiologically aroused (think racing heart, sweaty palms), they use environmental cues to help them determine why they are feeling that way.
Very few studies have used an evolutionary approach to help understand fictional heroes, and none have directly addressed how the sex of the author might influence the characteristics of the hero. If evolved behavioral differences in the sexes have influenced the subconscious tendencies of human males and females, these differences should be reflected in the fictional characters each creates. Based on sexual selection and inclusive fitness theory, I predicted that females will be more likely than males to create heroes who have family members, and that family members will be more important in the plotlines of female-generated stories. Information collected from twenty children’s fantasy novels published after 1994 display the predicted trends.
In addition, male authors often created parents who were problematic (insane, irresponsible, or evil), something the female authors never did.

There is an extensive literature dealing with English imperative sentences.
As is well known, these sentences have no overt grammatical subject: (1) Close the door. There is general agreement among scholars that these sentences have deep structures involving an underlying subject, “you,” which is deleted by a transformation.
There is a widespread misconception that utterances such as (2) Fuck you, which also appear to have the form of a transitive verb followed by a noun phrase and preceded by no overt subject, are also imperative. This paper will study the syntax of sentences such as (2).

On the day his country exploded, Santiago Bilinkis stayed at home and watched the riots on television with his wife and infant son. It was painful. In Buenos Aires, one of the world’s great cities, looters were attacking grocery stores. Bilinkis’s bank account—along with every other account in the country—had been frozen by executive decree three weeks earlier. Argentina was out of money.
This was December 20, 2001, a Thursday. (…)
The meltdown of 2008—which nearly destroyed the world’s banking system, sent the United States into its worst recession in 80 years, and put half of Western Europe on the brink of economic collapse—barely registered in Argentina. Andy Freire, Bilinkis’s co-founder at Officenet, told me that he finds it hard not to laugh when his American friends complain about their problems. “Retail sales fall 5 percent in the U.S., and people say it’s a major crisis,” Freire says. “Our sales went down 65 percent in a single month. That’s a crisis.”
The number of people we can truly be friends with is constant, regardless of social networking services like Twitter, according to a new study of the network.
Back in early 90s, the British anthropologist Robin Dunbar began studying the social groups of various kinds of primates. Before long, he noticed something odd.
Primates tend to maintain social contact with a limited number of individuals within their group. But here’s the thing: primates with bigger brains tended to have a bigger circle of friends. Dunbar reasoned that this was because the number of individuals a primate could track was limited by brain volume.
Then he did something interesting. He plotted brain size against number of contacts and extrapolated to see how many friends a human ought to be able to handle. The number turned out to be about 150.
Since then, various studies have actually measured the number of people an individual can maintain regular contact with. These all show that Dunbar was just about spot on (although there is a fair spread in the results).
What’s more, this number appears to have been constant throughout human history–from the size of neolithic villages to military units to 20th century contact books.
But in the last decade or so, social networking technology has had a profound influence on the way people connect. Twitter, for example, vastly increases the ease with which we can communicate with and follow others. It’s not uncommon for tweeters to follow and be followed by thousands of others.
So it’s easy to imagine that social networking technology finally allows humans to surpass the Dunbar number. Not so say Bruno Goncalves and buddies at Indiana University.

In the four billion years since life on Earth began, there have been five times when there was a sudden mass extinction of life-forms. The last time was 65 million years ago, when the dinosaurs were killed, probably by a meteor. But now the world’s scientists agree that the sixth mass extinction is at hand. Humans have accelerated the rate of species extinction by a factor of at least 100, and the great Harvard biologist EO Wilson warns that it could reach a factor of 10,000 within the next 20 years. We are doing this largely by stripping species of their habitats. We are destroying the planet’s biodiversity, and so we are making the natural chains that keep us alive much more vulnerable to collapse. This time, we are the meteor.
At the same time, we are dramatically warming the atmosphere. I know it has become terribly passé to listen to virtually all the world’s scientists, but I remember the collapsing glaciers I saw in the Arctic, the drying-out I saw in Darfur, and the rising salt water I saw in Bangladesh. 2010 was the joint-hottest year ever recorded, according to Nasa. The best scientific prediction is that we are now on course for a 3ft rise in global sea levels this century. That means goodbye London, Cairo, Bangkok, Venice and Shanghai. Doubt it if you want, but the US National Academy of Sciences – the most distinguished scientific body in the world – just found that 97 per cent of scientific experts agree with the evidence.

Let me toss out the idea that, as our markets discover and respond to what consumers most want, our technology has become extremely adept at creating products that correspond to our fantasy ideal of an erotic relationship, in which the beloved object asks for nothing and gives everything, instantly, and makes us feel all powerful, and doesn’t throw terrible scenes when it’s replaced by an even sexier object and is consigned to a drawer.
If art is a kind of lying, then lying is a form of art, albeit of a lower order—as Oscar Wilde and Mark Twain have observed. Both liars and artists refuse to accept the tyranny of reality. Both carefully craft stories that are worthy of belief—a skill requiring intellectual sophistication, emotional sensitivity and physical self-control (liars are writers and performers of their own work). Such parallels are hardly coincidental, as I discovered while researching my book on lying. Indeed, lying and artistic storytelling spring from a common neurological root—one that is exposed in the cases of psychiatric patients who suffer from a particular kind of impairment.
A case study published in 1985 by Antonio Damasio, a neurologist, tells the story of a middle-aged woman with brain damage caused by a series of strokes. She retained cognitive abilities, including coherent speech, but what she actually said was rather unpredictable. Checking her knowledge of contemporary events, Damasio asked her about the Falklands War. This patient spontaneously described a blissful holiday she had taken in the islands, involving long strolls with her husband and the purchase of local trinkets from a shop. Asked what language was spoken there, she replied, “Falklandese. What else?”
In the language of psychiatry, this woman was ‘confabulating’. Chronic confabulation is a rare type of memory problem that affects a small proportion of brain-damaged people. In the literature it is defined as “the production of fabricated, distorted or misinterpreted memories about oneself or the world, without the conscious intention to deceive”. Whereas amnesiacs make errors of omission—there are gaps in their recollections they find impossible to fill—confabulators make errors of commission: they make things up. Rather than forgetting, they are inventing.
In recent years, nightlife has been increasingly recognized as an important resource for the enhancement of the post-industrial profile of the city and for the promotion of gentrification in derelict neighborhoods. It projects an image of a vibrant social and cultural life, considered particularly appealing to the young professional labour force of post-industrial sectors, the members of whom are particularly apt to consider moving to the city. However, the advocates of this ‘nightlife fix’ thesis ignore tensions that have emerged between residents in gentrifying neighborhoods and nightlife businesses due to the nuisance effects of the latter. Using the example of New York City, this paper examines how conflicts over nightlife in gentrifying neighborhoods have resulted in the gentrification of nightlife and have thus transformed the nature of the city’s nightlife itself.
