FOR the past two years in Silicon Valley, the centre of America’s technology industry, conference-goers have entertained themselves playing a guessing game: how many times will a speaker mention the phrase "long tail" It is usually a high number, thanks to the influence of the long tail theory, which was first developed by Chris Anderson, the editor of Wired magazine, in an article in 2004. Though technologists and bloggers chuckle at how every business presentation now has to have its long-tail section, most are envious of Mr Anderson, whose brainwave quickly became the most fashionable business idea around.
Whether a blockbuster film, a bestselling novel, or a chart-topping rap song, popular culture idolizes the hit. Companies devote themselves to creating them because the cost of distribution and the limits of shelf space in physical shops mean that profitability depends on a high volume of sales. But around the beginning of this century a group of internet companies realized that with endless shelves and a national or even international audience online they could offer a huge range of products—and make money at the same time.
The niche, the obscure and the specialist, Mr Anderson argues, will gain ground at the expense of the hit. As evidence, he points to a drop in the number of companies that traditionally calculate their revenue/sales ratio according to the 80/20 rule—where the top fifth of products contribute four-fifths of revenues. Ecast, a San Francisco digital jukebox company, found that 98% of its 10,000 albums sold at least one track every three months. Expressed in the language of statistics, the experiences of Ecast and other companies such as Amazon, an online bookseller, suggest that products down in the long tail of a statistical distribution, added together, can be highly profitable. The internet helps people find their way to relatively obscure material with recommendations and reviews by other people and (for those willing to have their artistic tastes predicted by a piece of software) computer programs which analyze past selections.
Long-tail enthusiasts argue that the whole of culture will benefit, not just commercial enterprises. Television, film and music are such bewitching media in their own right that many people are quite happy to watch and listen to what the mainstream provides. But if individuals have the opportunity to pick better, more ideally suited entertainment from a far wider selection, they will take it, according to the theory of the long tail. Some analysts reckon that entire populations might become happier and wiser once they have access to thousands of documentaries, independent films and sub-genres of every kind of music, instead of being subjected to what Mr Anderson calls the tyranny of lowest-common-denominator fare. That might be taking things a bit far. But the long tail is certainly one of the internet’s better gifts to humanity.

Europa’swatery underworld 　　Europa, one of Jupiter’s 63 known moons,looks bright and icy on the surface. But appearances can be deceiving: Mileswithin its cracked, frigid shell, Europa probably hides giant pools of liquidwater. Where scientists find liquid water, they hope to find life as well. 　　Since we can’t go diving into Europa’sdepths just yet, scientists instead have to investigate the moon’s surface forclues to what lies beneath. In a new study, scientists investigated one groupof strange ice patterns on Europa and concluded that the formations mark thetop of an underground pool that holds as much water as the U.S. Great Lakes. 　　Pictures of Europa, which is slightlysmaller than Earth’s moon, clearly show a tangled, icy mishmash of lines andcracks known as “chaos terrains.” These chaotic places cover more than half ofEuropa. For more than 10 years, scientists have wondered what causes theformations. The new study suggests that they arise from the mixing of vastunderground stores of liquid water with icy material near the surface. 　　For scientists who suspect that Europaalso may be hiding life beneath its icy surface, the news about the new lake isexciting. 　　“It would be great if these lakesharbored life,” Britney Schmidt, a planetary scientist who worked on the study,told Science News. “But even if they didn’t, they say that Europa is doingsomething interesting and active right now.” 　　Schmidt, a scientist at the University of Texas at Austin, and her colleagueswanted to know how chaos terrains form. Since they couldn’t rocket to Europa tosee for themselves, they searched for similar formations here on Earth. Theystudied collapsed ice shelves in Antarctica and icy caps on volcanoes in Iceland. Thosefeatures on Earth formed when liquid water mixed with ice. The scientists nowsuspect something similar might be happening on Europa: that as water and iceof different temperatures mingle and shift, the surface fractures. This wouldexplain the jumbled ice sculptures. 　　“Fracturing catastrophically disruptsthe ice in the same way that it causes ice shelves to collapse on Earth,”Schmidt told Science News. She and her team found that the process could becausing chaos terrains to form quickly on Europa. 　　The new study suggests that on thismoon, elements such as oxygen from the surface blend with the deep bodies ofwater. That mixture may create an environment that supports life.　 The strange ice patterns on Europa are formed as a result of a xxxxx undergroundwater pool.
