Tool use is rare in wild animals, but of widespread interest because of its relationship to animal cognition, social learning and culture. Despite such attention, quantifying the costs and benefits of tool use has been difficult, largely because if tool use occurs, all population members typically exhibit the behavior. In Shark Bay, Australia, only a subset of the bottlenose dolphin population uses marine sponges as tools, providing an opportunity to assess both proximate and ultimate costs and benefits and document patterns of transmission. We compared sponge-carrying (sponger) females to non-sponge-carrying (non-sponger) females and show that spongers were more solitary, spent more time in deep water channel habitats, dived for longer durations, and devoted more time to foraging than non-spongers; and, even with these potential proximate costs, calving success of sponger females was not significantly different from non-spongers. We also show a clear female-bias in the ontogeny of sponging. With a solitary lifestyle, specialization, and high foraging demands, spongers used tools more than any non-human animal. We suggest that the ecological, social, and developmental mechanisms involved likely (1) help explain the high intrapopulation variation in female behaviour, (2) indicate tradeoffs (e.g., time allocation) between ecological and social factors and, (3) constrain the spread of this innovation to primarily vertical transmission.
In search of the Easy Fret
Music | “The success of Guitar Hero means that the onus is now on the manufacturers of ‘real’ guitars to make them easier,” a blogger says. “Why are they still making guitars with ‘real’ strings that are difficult and boring to learn how to play and really make your fingers hurt? What is the point?” Are musicians to be protected like some sort of medieval guild? [Guardian]
The Amish (a quaint static ripple whose way of life will never uncover the simplest new technological fix for the unfolding hazards of a dynamic universe) have long recognized that material culture embodies weird inspirations, challenging us, as eventual consumers, not with ‘copy what I do’, but a far, far more subversive ‘try me.’

Africa and missionaries, pt. 1
Now a confirmed atheist, I’ve become convinced of the enormous contribution that Christian evangelism makes in Africa: sharply distinct from the work of secular NGOs, government projects and international aid efforts. These alone will not do. Education and training alone will not do. In Africa Christianity changes people’s hearts. It brings a spiritual transformation. The rebirth is real. The change is good.
I used to avoid this truth by applauding - as you can - the practical work of mission churches in Africa. It’s a pity, I would say, that salvation is part of the package, but Christians black and white, working in Africa, do heal the sick, do teach people to read and write; and only the severest kind of secularist could see a mission hospital or school and say the world would be better without it. I would allow that if faith was needed to motivate missionaries to help, then, fine: but what counted was the help, not the faith.
But this doesn’t fit the facts. Faith does more than support the missionary; it is also transferred to his flock. This is the effect that matters so immensely, and which I cannot help observing.
Africa and missionaries, pt. 2
Majestic in a green chasuble, Father Ibemere delivered his homily strolling up and down the aisle. When it was time to distribute the eucharist, he bent down to give communion to a man he knew was too ill to stand.
After the Mass, however, one member of the congregation, Virginia Ballard, gestured toward the Nigerian priest and confided in Father Venters, “I can’t understand what he said, but he’s a sweet young man.”
Mrs. Ballard went on to praise Father Ibemere’s knowledge of the Bible, his capacity to remember the names of congregants, his willingness to teach the Americans about his home in Nigeria. “He is a holy man,” she concluded, “and we are honored to have him.”
Lazy futures
Why is the dystopian future always literally dark? Why is it always raining or overcast? Why is the architecture always a mix of hyper-modernism, brutalism and squatter slum? Why is the politics always so transparently totalitarian, so fascist-plus-rebels? Why is it so retro and abstract?
Why doesn’t the dystopian vision ever include sunshine and children playing in its ruins? Why does it not include the constant, untiring efforts of most people to do what they can with what they have to improve their situations? Why are most people in the dystopian future always powerless to change anything? I could go on, but you get the point.
The biggest problem with dystopian fiction is not its pessimism. I do think there’s a serious issue about who’s interests are best served by making people fear the future, but I think the biggest problem with most dystopian fiction is its laziness and derivative quality. Lazy futures act like visionary static, crackling and dirtying the signal-to-noise ratio, making it harder not only for truly insightful futures to be found, but corrupting the ability of normal people to see why those visions are worth understanding.

Food stamps and farmers markets

In the 2008 farm bill, Congress allocated $20 million for a pilot program to explore how to create incentives to purchase fruits, vegetables or other healthful foods in order to improve the diets of food stamp recipients and potentially reduce obesity. Several nonprofit groups and foundations are experimenting with similar incentives.
One is the Wholesome Wave Foundation, an organization that works to make locally grown food more widely available. In the spring, it launched a program that doubles the value of food stamps and fruit and vegetable vouchers of low-income mothers and seniors who use them at farmers markets in Connecticut, Massachusetts and California.The Wholesome Wave matching grants were an instant hit at the City Heights market in San Diego. On the first day that matching funds became available, sales using government-issued electronic benefit cards soared by more than 200 percent. In subsequent weeks, the line to receive matching vouchers formed at 7:30 a.m., and the available funds were exhausted by 9:30 a.m., just 30 minutes after the market opened.
“We’re not taking away your benefits because you spend them on Twinkies,” said Michel Nischan, a Connecticut chef and president of Wholesome Wave. “But if you decide you want to spend it on fresh tomatoes, you’ll get double your money.”
Namaste in six key presses
Texting is the cheapest and most popular mode of cellphone communication in most of the world, and last year text messages topped voice calls even in the U.S. The world’s three billion cellphones far surpass the Internet as a universal communications medium, and they are vital to business development in less-developed economies.
But companies that develop predictive text say they have created cellphone software for fewer than 80 of the world’s 6,912 languages cataloged by SIL International, a Dallas organization that works to preserve languages.
One key to using the languages is the availability of a technology called predictive text, which reduces the number of key taps necessary to create a word when using a limited keypad. Market research shows that text messaging soars after predictive text becomes available. . . .
In Hindi, a language with 11 vowels and 34 consonants that is spoken by 40% of the Indian population, texting “Namaste,” which means “hello,” can take 21 key presses. . . . Typing “Namaste” with predictive text takes just six key presses. Nuance Corp. of Burlington, Mass., which dominates the predictive-text market, says that in 2006 cellphone users in India with predictive text in their handsets averaged 70 messages a week; those without it averaged 18.
Life is elsewhere
A Romantic, says Nietzsche, is someone who always wants to be elsewhere. If that’s so, then the children of the Internet are Romantics, for they perpetually wish to be someplace else, and the laptop reliably helps take them there — if only in imagination. The e-mailer, the instant messenger, the Web browser are all dispersing their energies and interests outward, away from the present, the here and now. The Internet user is constantly connecting with people and institutions far away, creating surrogate communities that displace the potential community at hand.
Then too, booking by computer has made travel easier and, by eliminating a certain number of middlemen, kept it reasonably cheap. So there’s an inducement to take off physically as well. The Internet is perhaps the most centrifugal technology ever devised. The classroom, where you sit down in one space at one time and ponder a text or an issue in slow motion, is coming to feel ever more antiquated. What’s at a premium now is movement, making connections, getting all the circuitry fizzing and popping.
For students now, life is elsewhere. Classes matter to them, but classes are just part of an ever-enlarging web of activities and diversions. Students now seek to master their work — not to be taken over by it and consumed. They want to dispatch it, do it well and quickly, then get on to the many other things that interest them. For my students live in the future and not the present; they live with their prospects for success and pleasure. They dwell in possibility.
Like sentiment, which has been called unearned emotion, the new irony is a form of unearned skepticism. It creates nothing of its own but waits to ambush moral purpose, to play havoc with common sense, to deny reason its moment.
—Benjamin Barber, "The Price of Irony"
Visitors and collectors
The experience of purchasing art shares much in common with viewing it in exhibits, according to a new study in the Journal of Consumer Research. Author Yu Chen (Oakland University) shows that visiting a gallery can provide many of the same benefits as buying a painting....
The author found that art collectors and visitors to galleries and museums share many desires and values, including otherness, sociality, philanthropy, spirituality, aesthetics, and novelty. How collectors differ from visitors is in their desire for a long-term intimate relationship with the artworks. Visitors want to avoid repetition and dullness, and like the experience of sharing art communally.
Chen also found that the experiences of both art purchasers and art viewers do not always correspond with their expectations. “This contradiction implies that desire and illusions, more than value and perceptions, are the driving forces behind consumption,” writes Chen.
