Nanotubes may heal broken bones

From Wired News:Bone_1

Human bones can shatter in accidents, or they can disintegrate when ravaged by disease and time. But scientists may have a new weapon in the battle against forces that damage the human skeleton.  Carbon nanotubes incredibly strong molecules just billionths of a meter wide, can function as scaffolds for bone regrowth, according to researchers led by Robert Haddon at  the University of California at Riverside. They have found a way to create a stronger and safer frame than the artificial bone scaffolds currently in use.

IN DEFENSE OF COMMON SENSE

From The Edge:

Horgan200_1 John Horgan, author of The End of Science, and feisty and provocative as ever, is ready for combat with scientists in the Edge community. “I’d love to get Edgies’ reaction to my OpEd piece — “In Defense of Common Sense” — in The New York Times”, he writes.

Susskind100 Physicist Leonard Susskind, writing “In Defense of Uncommon Sense”, is the first to take up Horgan’s challenge. Susskind notes that in “the utter strangeness of a world that the human intellect was not designed for… physicists have had no choice but to rewire themselves. Where intuition and common sense failed, they had to create new forms of intuition, mainly through the use of abstract mathematics.” We’ve gone “out of the range of experience.”

The lost sub-continent

From The Guardian:

India_1 Seven years ago, publishers descended on Delhi in search of the next Arundhati Roy. But, writes William Dalrymple, the future Anglophone Indian bestsellers are more likely to come from the west. There is a wonderfully telling line in Mira Nair’s movie Monsoon Wedding: as the Verma family gathers from across the globe for a marriage, the heroine announces that she has applied for a creative-writing programme in America. Her businessman uncle nods approvingly: “Lots of money in writing these days,” he says sagely. “Look at that girl who won the Booker: she became a millionaire overnight.” If it was the literary merit of Arundhati Roy’s novel, The God of Small Things, that made the greatest impression on readers and critics in the west, it is fair to say that it was the size of her advance- more than $1 million in total – that made the most impression in Delhi. India has always had an enviable glut of talented writers; what has been much rarer, until recently, have been Indian writers who have been properly remunerated for their work (or indeed widely read outside India). The Robert Frost line – “There’s no money in poetry, but then there’s no poetry in money” – used to be true of even the most successful South Asian authors: the letters of the greatest of all Urdu poets, Mirza Ghalib, are full of endless worries as to whether he could pay his bills or afford to drink his beloved firangi wine.

Mr. Afghanistan

From CNN:

VstorymrafghanistanKhosraw Basheri feverishly pumped iron for years, toning his body so it rippled with muscle and veins. His hard work paid off when he claimed a historic title in his war-battered country — Mr. Afghanistan.

The 23-year-old businessman from western Herat province flexed and grinned his way to victory Saturday in Afghanistan’s first-ever national competition to select a top bodybuilder.

“I will never forget this day, the day I became Mr. Afghanistan,” said Basheri, sweat and makeup streaming down his massive frame. “This has been my hope for the past two years, since I started preparing myself for this.”

PAKISTAN ZINDABAD!

From Dawn:

FlagThe nation is celebrating the 59th Independence Day on Sunday with a renewed pledge to work hard for making the country prosperous, moderate and an Islamic democratic welfare state.

The day will dawn with a 31-gun salute in the federal capital and a 21-gun salute in all the provincial capitals. Special prayers will be offered after morning prayers.

Silence will be observed at 7:58am Sunday morning after the sounding of sirens to herald the flag-hoisting ceremonies throughout the country. All traffic will stop for a minute.

Prime Minister Shaukat Aziz who will be the chief guest, will unfurl the national flag at the flag-hoisting ceremony to be held at the Jinnah Convention Centre here at 8am.

Later, he will deliver his special message to the nation for the Day. School children will also present national songs on the occasion.

Read Mohammad Ali Jinnah’s message to the nation on independence day, 1947:

JinnahazamIt is with feelings of greatest happiness and emotion that I send you my greetings. August 15 is the birthday of the independent and sovereign State of Pakistan. It marks the fulfillment of the destiny of the Muslim nation which made great sacrifices in the past few years to have its homeland.

At this supreme moment my thoughts are with those valiant fighters in our cause. Pakistan will remain grateful to them and cherish the memory of those who are no more.

The creation of the new State has placed a tremendous responsibility on the citizens of Pakistan. It gives them an opportunity to demonstrate to the world how can a nation, containing many elements, live in peace and amity and work for the betterment of all its citizens, irrespective of caste or creed.

Our object should be peace within and peace without. We want to live peacefully and maintain cordial and friendly relations with our immediate neighbors and with the world at large. We have no aggressive designs against any one. We stand by the United Nations Charter and will gladly make our full contribution to the peace and prosperity of the world.

ShahziaShahzia Sikander was born in 1969 in Lahore, Pakistan. Educated as an undergraduate at the National College of Arts in Lahore, she received her MFA in 1995 from the Rhode Island School of Design. Sikander specializes in Indian and Persian miniature painting, a traditional style that is both highly stylized and disciplined. While becoming an expert in this technique-driven, often impersonal art form, she imbued it with a personal context and history, blending the Eastern focus on precision and methodology with a Western emphasis on creative, subjective expression. In doing so, Sikander transported miniature painting into the realm of contemporary art. Reared as a Muslim, Sikander is also interested in exploring both sides of the Hindu and Muslim “border,” often combining imagery from both—such as the Muslim veil and the Hindu multi-armed goddess—in a single painting. Sikander has written: “Such juxtaposing and mixing of Hindu and Muslim iconography is a parallel to the entanglement of histories of India and Pakistan.” Expanding the miniature to the wall, Sikander also creates murals and installations, using tissue paperlike materials that allow for a more free-flowing style. In what she labeled performances, Sikander experimented with wearing a veil in public, something she never did before moving to the United States. Utilizing performance and various media and formats to investigate issues of border crossing, she seeks to subvert stereotypes of the East and, in particular, the Eastern Pakistani woman. Sikander has received many awards and honors for her work, including the honorary artist award from the Pakistan Ministry of Culture and National Council of the Arts. Sikander resides in New York and Texas.

The struggle for Islam’s soul

“While most Muslims abhor violence, some terrorists are a product of a specific mindset with deep roots in Islamic history. If Muslims everywhere refuse to confront this, we will all be prey to more terror, writes Ziauddin Sardar.”

From the Toronto Star:

SardarIt is true that the vast majority of Muslims abhor violence and terrorism, and that the Qur’an and various schools of Islamic law forbid the killing of innocent civilians. It is true, as the vast majority of Muslims believe, that the main message of Islam is peace. Nevertheless, it is false to assume the Qur’an or Islamic law cannot be used to justify barbaric acts. The terrorists are a product of a specific mindset that has deep roots in Islamic history. They are nourished by an Islamic tradition that is intrinsically inhuman and violent in its rhetoric, thought and practice.

They are provided solace and spiritual comfort by scholars, who use the Qur’an and Islamic law to justify their actions and fan the hatred.

As a Muslim, I am deeply upset by the attacks, the more so now I know they were the work of British Muslims. But, as a Muslim, I also have a duty to recognize the Islamic nature of the problem that the terrorists have thrown up.

They are acting in the name of my religion; it thus becomes my responsibility critically to examine the tradition that sustains them.

The question of violence per se is not unique to Islam. All those who define themselves as the totality of a religion or an ideology have an innate tolerance for and tendency toward violence. It is the case in all religions and all ideologies through every age.

But this does not lessen the responsibility on Muslims in Britain, or around the world, to be judicious, to examine themselves, their history and all it contains to redeem Islam from the pathology of this tradition. To deny that the terrorists are a product of Islamic history and tradition is more than complacency. It is a denial of responsibility, a denial of what is really happening in our communities. It is a refusal to live in the real world.

The tradition that nourishes the mentality of the extremists has three inherent characteristics…

Matters of Gravity

Lee Smolin reviews Gravity’s Shadow: The Search for Gravitational Waves by Harry Collins, in American Scientist:

…despite the several billions invested in particle accelerators and detectors, there have been few truly major experimental discoveries in fundamental physics in the past 20 years. The fields that have continued to amaze are astronomy and cosmology, which are obviously healthy. But the only major addition to our knowledge of the elementary particles these past two decades was the discovery that neutrinos have mass. The list of new particles or effects that have been looked for—and so far not found—is longer: the Higgs particle, supersymmetric particles, dark-matter particles, proton decay, the fifth force, evidence of extra dimensions.

It is, then, very timely that Harry Collins has written a first-class study of how contemporary experimental physics operates. Collins is a distinguished sociologist, and in Gravity’s Shadow he demonstrates why it is important to go beyond superficial characterizations of science to study how groups of scientists actually work together and make decisions. Collins has taken as his subject the search for gravitational radiation.

Gravitational waves are ripples in the geometry of spacetime, analogous to electromagnetic waves. Just as moving charges and magnets produce light waves, masses when they accelerate inevitably produce waves in the gravitational field—a field that, as Einstein discovered in working out his theory of general relativity, is exactly the same as the geometry of space and time.

Archives of interviews, dispatches tapes, phone logs . . . of 9/11

From The New York Times and the city of New York:

“Faced with a court order and unyielding demands from the families of victims, the city of New York yesterday opened part of its archive of records from Sept. 11, releasing a digital avalanche of oral histories, dispatchers’ tapes and phone logs so vast that they took up 23 compact discs.

For the first time, about 200 accounts of emergency medical technicians, paramedics and their supervisors were made public, revealing new dimensions of a day and an emergency response that had already seemed familiar.

In details large and small, the accounts of the medical personnel – uniformed workers who were often overlooked in many of the day’s chronicles, but were as vital to the response and rescue efforts as any others – provide vivid and alarming recollections.

They spoke of being unable to find anyone in authority to tell them where to go or what to do. Nearly from the moment the first plane struck the World Trade Center, they had little radio communication. As their leaders struggled to set up ordinary procedures for a “mass casualty incident,” the crisis gathered speed by the minute.”

The secret life of sperm

From Nature:

Sperm_2 “What’s in sperm?” demands Tim Karr. Because sperm have to swim far and fast, biologists have come to view them like racing cars: streamlined and stripped down of all unnecessary bits and pieces. Generally speaking, the DNA in animal sperm is tightly packed inside a sleek head structure that contains little of the cytoplasm that fills most other cells. Behind the head is the midpiece, containing more than 50 power units called mitochondria that drive the lashing motion of the attached tail. But what does a sperm deliver? One popular misconception is that only the head enters the egg, while the tail is discarded. But in most species, the entire cell enters the egg — midpiece, tail and all. And in many mammals, midpiece and tail structures persist in the embryo for several cell divisions. This results in a large number of proteins and other molecules being delivered to the egg.

‘Friedrich Nietzsche’: The Constructive Nihilist

From The New York Times:

Nietzhe_1 Nietzsche was born in Rocken, Prussia, in 1844, and died, having gone insane, in 1900. He was educated at Bonn and Leipzig and was self-educated (and dis-educated) thereafter. But who, really, was he? Heidegger is onto something when he advises us that philosophy can be possessed ”most purely in the form of a persistent question,” and that ”Nietzsche’s procedure, his manner of thinking in the execution of the new valuation, is perpetual reversal,” perhaps like life itself, not to mention Heidegger’s own devoted explications of Nietzsche. That arch-muse Lou Salomé, who knew him not only as a thought machine but also as a lover of sorts, stated the case more intimately when she wrote, ”In Nietzsche the most abstract thoughts habitually could reverse themselves into the power of moods which could carry him off with immediate and unpredictable force.”

Ecce homo, behold the man! As we peer down time’s long barrel to try to see him, his hand keeps turning the kaleidoscope.

Africa and Its Rapacious Leaders

Janet Maslin reviews The Fate of Africa: A History of 50 Years of Independence by Martin Meredith, in the New York Times Book Review:

08maslIn the words of an African proverb cited in Martin Meredith’s Sisyphean new volume: “You never finish eating the meat of an elephant.” That thought is summoned by the overwhelmingly difficult assignment that this historian, biographer and journalist has given himself. He has set out to present a panoramic view of African history during the past half century, and to contain all its furious upheaval in a single authoritative volume.

Everything about this subject is immense: the idealism, megalomania, economic obstacles, rampant corruption, unimaginable suffering (AIDS, famine, drought and genocide are only its better-known causes) and hopelessly irreconcilable differences leading to endless warfare. “The rebels cannot oust the Portuguese and the Portuguese can contain but not eliminate the rebels,” read a typically bleak 1969 American assessment of a standoff in Guinea-Bissau.

For the author, even organizing this information is a hugely daunting job. How can such vast amounts of information be analyzed for the reader? One way was to follow parallel developments in different places – which is more or less how Mr. Meredith works, with attention to the hair-trigger ways in which one coup or crisis could set off subsequent disasters. He is able to steer the book firmly without compromising its hard-won clarity.

IGNATIUS DONNELLY, PRINCE OF CRANKS

3 Quarks Daily editor J.M. Tyree has a funny piece in The Believer. Unfortunately, the entire essay is available only to subscribers. Nevertheless, here is a bit, with a link to the rest of the teaser:

Tyree202_1The opposite of a Renaissance man, presumably, would be someone who tried his hand at a number of different things and failed at all of them. Mostly forgotten today, Ignatius Donnelly (1831–1901) is worth a second look because he is quite possibly the greatest failure who ever lived. Donnelly, a bestselling writer and reform-minded congressman from Minnesota, might be dubbed the Great American Failure. Among the things that Donnelly failed to do were: build a city, reform American politics, reveal the facts about Atlantis, discover a secret code in Shakespeare, and prove that the world’s gravel deposits were the result of a collision with a comet. His dire political prophecies of class warfare and the imminent collapse of civilization also failed to come true.

Donnelly genuinely believed he was a genius, and that, by applying his mental powers to any problem, no matter how tangled or intractable, and regardless of the established body of relevant scholarship or scientific tradition, he could solve it with a fresh look. He was a kind of secular prophet, a combination of demagogue and revivalist tent-preacher, destined, he believed, to do great things. If Donnelly were alive today, he would probably be a “guru” on the lecture circuit, fervently putting forward his latest Theory of Everything. Congressman, master orator, pseudoscientist, student of comparative mythology, crackpot geologist, futurist, amateur literary sleuth, bogus cryptologist, Donnelly did it all with a charmingly boundless energy and a voracious intellectual appetite that utterly outstripped his real abilities.

The Truth About Jihad

Max Rodenbeck reviews five recent books in the New York Review of Books:

Aug20_cnnosamavideosAmerica’s past offers many examples of seeming setbacks being turned to dramatic and lasting advantage. The sinking of the battleship Maine is one that comes to mind, or of the liner Lusitania by a German U-boat, or of half the Pacific fleet at Pearl Harbor. More recently, the Soviet invasion of Afghanistan exposed a vein that allowed America and its allies to bleed the decaying Evil Empire, just as Saddam Hussein’s lunge at Kuwait in 1990 revealed an opportunity to score a number of American goals, from smashing this dangerous man’s army, to testing and displaying the power of new weapons, to warning potential rivals away from the Gulf’s crucial oil resources.

All these strategic overreactions had something in common. In each case, the identity and nature of the enemy were abundantly clear. In most such cases, too, little discussion took place to clarify the stakes involved, the advantages to be gained, or the optimum means for winning them. (Which usually meant the application of overwhelming force.)

Yet while the strikes against New York and Washington seemed to fit the first part of this historical template, they did not quite suit the rest. Here was yet another of the “sneak attacks” that seem to have punctuated America’s rise, demanding yet another crushing response. But where and who was the enemy? What was his motivation for attacking in the first place? What, beyond merely destroying this adversary, was the strategic prize waiting to be gained, a prize that surely must be worthy of an unchallenged global superpower? Which were the appropriate tools to be used for this broader mission? What were the risks?

By now it is clear that in pursuing the grand counterstroke, American policy has gone somewhat astray.

In Defense of Common Sense

John Horgan’s op-ed in the New York Times:

20050812_horgan2_184To commemorate Einstein’s “annus mirabilis,” a coalition of physics groups has designated 2005 the World Year of Physics. The coalition’s Web site lists more than 400 celebratory events, including conferences, museum exhibits, concerts, Webcasts, plays, poetry readings, a circus, a pie-eating contest and an Einstein look-alike competition.

In the midst of all this hoopla, I feel compelled to deplore one aspect of Einstein’s legacy: the widespread belief that science and common sense are incompatible. In the pre-Einstein era, T. H. Huxley, a k a “Darwin’s bulldog,” could define science as “nothing but trained and organized common sense.” But quantum mechanics and relativity shattered our common-sense notions about how the world works. The theories ask us to believe that an electron can exist in more than one place at the same time, and that space and time – the I-beams of reality – are not rigid but rubbery. Impossible! And yet these sense-defying propositions have withstood a century’s worth of painstaking experimental tests.

As a result, many scientists came to see common sense as an impediment to progress not only in physics but also in other fields.

The Big Gulp

“NASA pisses away millions hauling H2O into orbit. But there’s a better way – recycle astronaut urine. Just one question: How does it taste?”

Ff_82_urine_fTom McNichol in Wired:

People head to Reno for all sorts of reasons. Some want to gamble. Others are looking for a hasty wedding or quickie divorce. I’ve come to the Biggest Little City in the World to drink my own pee. Not straight up, of course. First, I’ll run it through a new NASA water purification system that collects astronaut sweat, moisture from respiration, drain water, and urine – and turns it all into drinking water.

NASA desperately needs this technology. Water makes for a heavy – and expensive – payload. Over the past five years, the agency has spent $60 million delivering potable water to the International Space Station on the space shuttle (6 tons at a cost of about $40,000 per gallon). Deploying the Water Recovery System on the ISS will cut the volume of water hauled into space by two-thirds and free up enough room on the shuttle for four more astronauts.

Mars Reconnaissance Orbiter Blasts Off for Red Planet

Anthony Duignan-Cabrera and Leonard David in Space.com:

H_mro_orbitart_02MRO was designed to be “NASA’s google search engine”, Garvin said, to cut down the number of compelling places both at the surface and below the martian landscape that cry out for future exploration.

The spacecraft is carrying a hefty science payload to Mars, with six instruments designed to track Martian weather, resolve objects on the surface the size of a kitchen table and measure the planet’s composition and atmospheric structure with more detail than ever before.

“The MRO spacecraft is many things,” Richard Zurek, the mission’s project scientist at NASA’s Jet Propulsion Laboratory (JPL), told SPACE.com prior to launch. “It’s aweather satellite, it’s a geological surveyor, and it’s a scout for future missions.”

The orbital spacecraft is expected to be the vanguard for two landers NASA plans to launch toward Mars in the next five years, and will identify potential landing targets. The Phoenix lander is currently scheduled to launch in 2007 and touchdown in the planet’s polar region. A large rover, the Mars Science Laboratory, is expected to launch in 2009.

Nobel Winner May Face Prison

Steve Chawkins in the Los Angeles Times:

18916449A 74-year-old Nobel laureate in physics may face prison time for slamming into a van at more than 100 mph last year, killing one passenger and injuring seven others just south of Santa Maria, Calif.

John Robert Schrieffer, a former professor at UC Santa Barbara who won the Nobel Prize in 1972 for a theory he helped formulate at the age of 26, was driving on a suspended Florida license at the time of the Sept. 24 collision, authorities said Wednesday. He had nine speeding tickets on his record.

At an emotional hearing this week in a Santa Maria courtroom, Schrieffer tearfully apologized to the crash victims, who are members of a Ridgecrest, Calif., family and their friends.

But Santa Barbara County Superior Court Judge James Herman was unmoved, sending Schrieffer to a state diagnostic facility where he is to be evaluated for a possible prison term.

Novices take on Booker all-stars

From The London Times:

Salman_2 DAVID took on Goliath yesterday when three first-time authors found themselves up against literary heavyweights on the longlist of the £50,000 Man Booker Prize. The publishing debut of Harry Thompson made such a dramatic impact on the Booker judges with his historical novel about Charles Darwin, This Thing Of Darkness, that they considered him worthy of comparison with J.M. Coetzee, who won the Nobel Prize for Literature in 2003 as well as the Booker in 1983 and 1999. In what was perceived as a particularly strong year for literature, this year’s list included Salman Rushdie, who won the “Booker of Bookers” for Midnight’s Children in 1993. This time, he has been longlisted for his forthcoming Shalimar the Clown, which is to be published next month.

Possible pattern found in Incan strings

From MSNBC:Inca_string_hmed2p

Three figure-eight knots tied into strings may be the first word from the ancient Inca in centuries. While the Incan empire left nothing that would be considered writing by today’s standards, it did produce knotted strings in various colors and arrangements that have long puzzled historians and anthropologists. Many of these strings have turned out to be a type of accounting system, but interpreting them has been complex. The findings are reported in Friday’s issue of the journal Science.

new economy gurus pilloried

Parent06096095801

Paul Maliszewski has a pretty amusing essay in The Baffler about Wacker and Mathews, a consulting team that helps businesses and organizations become more creative.

Wacker and Mathews say that they, like the alchemists of old, “challenge convention”; they show too much humility or perhaps are reluctant to brag. Ancient alchemists spent years of pointless experimentation and fruitless inquiry that resulted in only a few practical pay-offs and meager returns on their kings’ hefty capital investments. It was an alchemist, Wacker and Mathews claim, with not a little pride, who gave William the Conqueror the idea to fashion his army’s shields from hermatite, a hard mineral, more durable than wood, thus improving his ability to kick ass. Companies retaining the services and counsel of Wacker and Mathews cannot reasonably expect these two—“professional fools,” (http://firstmatter.com/promise.asp) as they call themselves—to help vanquish the competition and seize valuable market-share, or, for that matter, invade England. But don’t allow that failure, however obvious, to be the only measure of their value as authors, futurists, thinkers, and alchemists. Wacker and Mathews have in fact succeeded where every alchemist before them has failed. They have turned shit into gold.
