Sex-Changing Herbicide Makes Amphibians Sick, Too

From Wired:

Treefrog Though less obvious than gender bending, immunosuppression could play just as large a part in the worldwide decline of amphibians, which have porous skin and easily absorb chemicals from rain, groundwater and even water vapor. “Numerous studies have documented the effects of environmental pollutants on the amphibian immune system. Nearly all of these studies suggest that amphibians are particularly sensitive,” wrote Tyrone Hayes, a University of California, Berkeley biologist, in a paper published in the March 15 Journal of Experimental Biology. “In particular, the widespread herbicide atrazine impairs immune function and increases disease rates.”

Hayes is also an author of a March 1 Proceedings of the National Academy of Sciences study on the developmental changes wrought in male frogs by groundwater atrazine concentrations regularly found in the United States, where 80 million pounds of the herbicide are used every year. The frogs had low levels of sperm and testosterone; some even produced estrogen, developed female reproductive organs and were ultimately impregnated by their former gender mates.

Let’s all be friends

From Prospect Magazine:

New research shows how our social ties can influence us for better—and worse: making us fatter, more likely to smoke, marry, divorce and even vote. Governments should take heed

Friends If friends of your friends begin to put on weight, you are likely to do the same—even if you don’t know the people in question, and even if they live hundreds of miles away. Obesity spreads like a fad; it is contagious. This striking finding about how obesity spreads through social networks was the result of a 30-year study in Massachussetts, as Nicholas A Christakis and James H Fowler note in their new book, Connected: The Surprising Power of Social Networks and How They Shape Our Lives (HarperPress). Research shows that the same is true for smoking, and a range of other behaviours and attitudes like drinking, depression, charitable giving, sexual practices—even the decisions to marry, divorce, reproduce, or vote.

Why is this important? Because from healthcare to climate change, governments today face a range of problems where they must persuade people to change their behaviour. But instead of relying on their powers of persuasion, politicians should consider taking a class in “network science.” True, many claims for the power of social networks are based on the hype surrounding websites like Facebook. But the basic idea is simple: people join together in groups with particular patterns of ties, and these patterns then have important effects on the way they behave. The shape of these networks has surprising effects. Take an unlikely example: Broadway musicals. Brian Uzzi is a sociologist at Northwestern University in Chicago. He is also a big music hall fan. From Cats to Spamalot, musicals have been big business for decades, but investors have to guess which shows will be a hit. Bye Bye Birdie, a profitable 1960 production starring Dick van Dyke, ran for 607 nights. Bring Back Birdie, its 1981 sequel, was a flop and closed after just four.

Intrigued, Uzzi used network science to find out why.

The Idea of Communism: An Interview with Tariq Ali

Ali In History News Network (via bookforum):

You write, that “Marx and Engels would have been horrified by the suggestion that their writing might one day be elevated to the status of religion.” Yet it seems to continually landed in the hands of folks looking for a roadmap to heaven. How do you see this conflict, essentially between the content and the application of Marxism?

The very fact the idea of communism took off in two of the most backward societies at the beginning of the 20th Century — China and Russia — meant that the way it was picked up by many people, especially peasants and not so well educated people who joined in that revolutionary ferment was that the only way they could see it was as a secular religion, as a secular faith. The intellectuals who were initially won over the idea were of course not at all religious minded and by-in-large did not go in that direction or take Marxism in that direction either. If you look at the early Bolsheviks, most of who were of Jewish origin, they were cutting loose from religion— the were very much the great-grandchildren of the French Enlightenment. That was also the impact on the intellectuals in China who founded the Chinese Communist Party.

I don’t think there was anything in the theory that meant it should go in that direction. It was, I’ve always felt that the emergence of one-Party state, the emergence of all powerful Politburos and Central Committees, the emergence of a total monopoly of information and of ideas by the Party made it almost inevitable that they would transmit these ideas as ideas that were unchallengeable. If you challenged them you were a heretic or much worse than that, a traitor or an enemy of the people.

It was that form of application of Marxism that reminded me very much of the Spanish Inquisition which the Catholic Church used to use against Muslims and heretics in medieval Spain. It was when this dictatorship was imposed and free thought was more or less banished that the process took on this particular form.

Our Board-Game Renaissance

Monopoly Alexander Ewing in More Intelligent Life (for Jane Renaud):

After decades of decline, board games are back in vogue. In 2008 board-game sales reached $808m, an increase of 23% over the previous year. Industry insiders suggest that sales grew another 20% last year. The recession has helped many to reconsider the joys that can be found in cardboard and plastic pieces. And this has been an especially snowy winter, particularly in my hometown of Washington, DC, where we recently enjoyed our third blizzard of the season. Monopoly, the most popular board game in history, was introduced during the Great Depression, when the fun of play-acting as a vicious real-estate mogul perhaps was most plain. Players wielding pewter thimbles and doggies could malevolently corner a market and penalise hapless neighbours; getting out of prison involved paying a little fee.

The return of board games as a diversion is good news (and something we've written about before), but let’s set some parameters. I’m not keen on board games 2.0. Many of the new games on the market are insipid recreations of Charades or Pictionary, and are far too concerned with entertainment utility. What about the needs of the hyper-competitive and the overly-sensitive (ie, an important niche of board gamers)? Any game that requires a battery is sacrilegious. I’m also sceptical of anything “hands-on”. No Jenga or Cranium please. But Trivial Pursuit counts; it is just cards and a board, with ample room for humiliation.

Classics such as chess and checkers (draughts to the Brits) endure, but they are limited to two players and have been hijacked by the computer. If you play checkers, try the multi-player Chinese variety. Backgammon is my two-person exception; it is near and dear to my heart. As a boy I played regularly with my father. At university, recovering from a protracted and messy break-up, I started playing on the internet for money (usually losing it) and tried to improve by reading books like “Backgammon for Blood”, a 1970s strategy classic by Bruce Becker. It was a dark time.

Board games are more than recession-friendly recreation; they are rich in sociology. The Game of Life, invented by Milton Bradley, the godfather of board games, is America at its best and worst. The game features plastic mini-vans that you drive from birth to death, accumulating fellow passengers (a spouse and kids) and making loads of cash along the way, regardless of career (journalism was not one of the choices).

Christime Smallwood Talks to Martha Nussbaum

Nussbaum In The Nation:

You suggest that perhaps the state should get out of the marrying business altogether.

I guess the first thing to say is that they can't do it in a way that just simply takes away the possibility of marriage from gays and lesbians. During integration in the South there were attempts to get around mandatory integration by ending the program in question. They closed down the public swimming pools or the public schools rather than integrate them. That kind of thing has been held to be unconstitutional, and quite rightly so. But I guess I think that marriage as it currently exists is a weird institution. There are a bunch of civil benefits that could be captured in civil unions. There are religious elements, but they're not really part of state marriage. Then there's the expressive significance–we want the state to dignify or affirm our marriage. Should the state be in the business of dignifying certain unions? The answer would be no. If we were starting over again, we'd want to go back and look at the privileges associated with marriage–tax benefits, immigration status, etc.– and ask, Who do we want to give those benefits to? What do we want to do? That kind of thorough rethinking would be ideal, but it's also not likely to actually happen. How do we get from where we are to there? In the short run, I think the best thing is just to push on the equality issue and say, So long as marriage is offered by the state, it should be offered with an even hand.

Larry Fink’s $12 Trillion Shadow

Suzanna Andrews in Vanity Fair:

Fink Considering the enormous power he is believed to wield, it’s remarkable how few people have heard of Larry Fink. In political and business circles—among the men who travel the now well-worn corridor between Washington and Wall Street—Fink, the chairman and C.E.O. of BlackRock, the giant asset-management firm, is described as possibly the most important man in finance today. But mention his name to most people and they draw a blank. Despite his considerable wealth, he is virtually unknown on the society circuit in Manhattan, where he has an apartment on the Upper East Side, or in Aspen, where he also has a home. In North Salem, the affluent enclave north of New York City where he and Lori, his wife of 35 years, have a 26-acre farm, he is perhaps slightly better known, if only because a number of Wall Street bankers have estates there. But still—just a few months ago—when one of his neighbors, a prominent New York agent, furious that a popular horse path through the Fink estate had been blocked off, was told who owned the property, her response was: “Who is Larry Fink?”

The Chicago boys and the Chilean earthquake

Andrew Leonard in Salon:

Md_horiz The ghost of Milton Friedman, writes Bret Stephens in the Wall Street Journal, “was surely hovering protectively over Chile in the early morning hours of Saturday.”

Thanks largely to him, the country has endured a tragedy that elsewhere would have been an apocalypse.

Stephens' logic is simple. After the U.S.-backed coup in 1973, in which Gen. Pinochet seized power from the democratically elected president Salvador Allende, a group of Chilean economists mentored by Friedman, and known to history as “the Chicago boys,” instituted a series of radical free market reforms. Since that point, averaged over the decades, Chile has experienced the strongest sustained economic growth in South America. Rich countries, argues Stephens, are more likely to institute and enforce building codes. Q.E.D. Milton Friedman saved lives.

Some might find it intellectually provocative to cite Milton Friedman's authority in an argument that depends on the foundation of successfully enforced government-mandated building code regulations. The building inspector is not exactly a libertarian hero. Others might wonder if a more important factor in Chile's relatively tough building codes might be the devastating 9.5 earthquake the country endured in 1960.

Why Israeli Prime Minister Netanyahu repeats his errors

ScreenHunter_04 Mar. 03 06.59 By all accounts, Benjamin Netanyahu devoted very little thought to the two final sites added to a list of designated heritage sites set to benefit from a large government restoration budget. Never mind that the Tomb of the Patriarchs, known to Muslims as the Ibrahimi Mosque, is located in the West Bank town of Hebron. Likewise, Rachel's Tomb is in Bethlehem — also occupied territory. Just before Sunday's Cabinet meeting, rightist ministers noticed that the two shrines, regarded as the burial places of the biblical ancestors of the Jewish people, were missing from the list. They leaned a bit on Netanyahu, he added the tombs, and the Cabinet unanimously approved the plan.

From there, the reaction followed as if part of the playbill. Palestinian protests in Hebron turned into confrontations between demonstrators and troops that have grown larger each day. Palestinian negotiator Saeb Erekat described the heritage designation as a “unilateral decision to make Palestinian sites in Hebron and Bethlehem part of Israel,” and Palestinian President Mahmoud Abbas warned that the move “could cause a holy war.” A State Department spokesman condemned the Israeli step as “provocative.”

You might expect Netanyahu to be careful about playing with holy fire. In September 1996, early in his previous term as prime minister, he approved opening a tunnel alongside the Temple Mount, otherwise known as Haram al-Sharif. That set off a week-long mini war between Israel and Palestinians. How could he so easily give in to pressure and repeat the mistake of asserting ownership of contested holy places? While we're at it, how does a country declare that a place outside its borders is a national heritage site?

Less expensive, lower-quality innovations abound in every economic sector—except medicine

David Kent in American Scientist:

ScreenHunter_03 Mar. 03 06.53 To help maximize the overall benefits in health care under a utilitarian framework and conditions of constrained resources, health economists use an analytic tool called cost-effectiveness analysis (CEA) that quantifies the added expenditure necessary to obtain a unit of health benefit (typically measured in quality-adjusted life years or QALYs, pronounced “kwallies”). The most common application of CEA is to examine the value of medical innovations compared to the standard of care routinely available, since new technologies are an important cause of the increase in health-care costs.

If the “unit cost” for a QALY of benefit (that is, the cost-effectiveness ratio) is less than some threshold (conventionally $50,000 or $100,000 per QALY), then adoption of the innovation is deemed “incrementally cost-effective,” since the benefit obtained compares favorably to that obtainable at similar cost using accepted medical technologies (such as dialysis, which has a cost-effectiveness ratio variously estimated at between $50,000 and $80,000 per QALY). Above the ratio, they are deemed not to be cost-effective. That is, the (relatively small) incremental benefits of the intervention do not justify the (relatively large) incremental costs.

Genuine American exceptionalism on due process

Glenn Greenwald in his blog at Salon:

ScreenHunter_02 Mar. 03 06.29 In contrast to America's still-growing refusal to accord basic due process to accused Terrorists, consider how Pakistan treats foreigners whom it apprehends within its borders on serious charges of Terrorism:

SARGODHA, Pakistan — Prosecutors seeking to indict five Americans on terror-related offenses presented their case to a Pakistani judge Tuesday, laying out charges including waging war against Pakistan and plotting to attack the country, a defense attorney said.

The men, all young Muslims from the Washington, D.C., area, were arrested in December in Punjab province not long after reaching Pakistan. . . . The men could be indicted on as many as seven charges during their next hearing on March 10, lawyer Hamid Malik told The Associated Press. The judge ordered the defense to review the prosecution report presented in the Sargodha town court and to prepare a rebuttal.

If there's any country which can legitimately claim that Islamic radicalism poses an existential threat to its system of government, it's Pakistan. Yet what happens when they want to imprison foreign Terrorism suspects? They indict them and charge them with crimes, put them in their real court system, guarantee them access to lawyers, and can punish them only upon a finding of guilt. Pakistan is hardly the Beacon of Western Justice — its intelligence service has a long, clear and brutal record of torturing detainees (and these particular suspects claim they were jointly tortured by Pakistani agents and American FBI agents, which both governments deny). But just as is true for virtually every Western nation other than the U.S., Pakistan charges and tries Terrorism suspects in its real court system.

Planet Pakistan

Robert M. Hathaway in The Wilson Quarterly:

Pakistan An American visitor in Pakistan can’t help thinking at times that he has arrived in a parallel universe. Asked about the presence of Al Qaeda on their country’s soil, Pakistanis deny that there is any evidence of it. They lionize A. Q. Khan, who created the country’s nuclear weapons program and sold essential nuclear technology and knowledge to Iran, North Korea, and Libya, and they are incensed by American worries about the security of their country’s nuclear assets. Suicide bombings and political assassinations are near-daily occurrences, yet many Pakistanis are astonishingly complacent about the murderous groups behind them. They rail instead against the government that is powerless to prevent these attacks and an America that would like nothing better than to see an end to ­them.

Last October, when I visited, Pakistanis were fuming over the U.S. aid package recently approved by Congress. The $7.5 billion Kerry-­Lugar bill tripled American support for Pakistan over a ­five-­year period and reversed the overwhelmingly ­pro­military slant of previous U.S. aid. Instead of going almost entirely to the armed forces, American dollars will flow to schools and clinics, economic development, and efforts to promote the rule of law and democratic governance. Pakistan’s friends in Washington were jubilant. Yet most Pakistanis I spoke with insisted that because the aid came with ­conditions—­the U.S. secretary of state must certify that Pakistan is working to end government support for extremist and terrorist groups, for ­example—­it was an affront and a threat to their country’s sovereignty. One legislator complained that what Pakistan was being asked to accept was less an aid package than a treaty of ­surrender.

Denial is a national habit in Pakistan. With a long history of failed governance and political leaders who put their personal interests first, Pakistanis point their fingers at the United States, their arch-enemy India, or the ­all-­purpose malefactor often described in the local news media as the “hidden hand”—anyone but themselves to explain their nation’s past failings and precarious ­present.

Human Culture, an Evolutionary Force

Nicholas Wade in The New York Times:

Culture As with any other species, human populations are shaped by the usual forces of natural selection, like famine, disease or climate. A new force is now coming into focus. It is one with a surprising implication — that for the last 20,000 years or so, people have inadvertently been shaping their own evolution. The force is human culture, broadly defined as any learned behavior, including technology. The evidence of its activity is the more surprising because culture has long seemed to play just the opposite role. Biologists have seen it as a shield that protects people from the full force of other selective pressures, since clothes and shelter dull the bite of cold and farming helps build surpluses to ride out famine.

Because of this buffering action, culture was thought to have blunted the rate of human evolution, or even brought it to a halt, in the distant past. Many biologists are now seeing the role of culture in a quite different light. Although it does shield people from other forces, culture itself seems to be a powerful force of natural selection. People adapt genetically to sustained cultural changes, like new diets. And this interaction works more quickly than other selective forces, “leading some practitioners to argue that gene-culture co-evolution could be the dominant mode of human evolution,” Kevin N. Laland and colleagues wrote in the February issue of Nature Reviews Genetics. Dr. Laland is an evolutionary biologist at the University of St. Andrews in Scotland.

How Paul Krugman found politics

Larissa MacFarquhar in The New Yorker:

ScreenHunter_04 Mar. 02 10.20 For the first twenty years of Krugman’s adult life, his world was divided not into left and right but into smart and stupid. “The great lesson was the low level of discussion,” he says of his time in Washington. “The then Secretary of the Treasury”—Donald Regan—“was not that bright, and you could have angry exchanges where neither side understood the policy.” Krugman was buoyed and protected in his youth by an intellectual snobbery so robust that distractions or snobberies of other sorts didn’t stand a chance. “When I was twenty-eight, I wouldn’t have had the time of day for some senator or other,” he says.

Krugman’s tribe was academic economists, and insofar as he paid any attention to people outside that tribe, his enemy was stupid pseudo-economists who didn’t understand what they were talking about but who, with attention-grabbing titles and simplistic ideas, persuaded lots of powerful people to listen to them. He called these types “policy entrepreneurs”—a term that, by differentiating them from the academic economists he respected, was meant to be horribly biting. He was driven mad by Lester Thurow and Robert Reich in particular, both of whom had written books touting a theory that he believed to be nonsense: that America was competing in a global marketplace with other countries in much the same way that corporations competed with one another. In fact, Krugman argued, in a series of contemptuous articles in Foreign Affairs and elsewhere, countries were not at all like corporations. While another country’s success might injure our pride, it would not likely injure our wallets. Quite the opposite: it would be more likely to provide us with a bigger market for our products and send our consumers cheaper, better-made goods to buy. A trade surplus might be a sign of weakness, a trade deficit a sign of strength. And, anyway, a nation’s standard of living was determined almost entirely by its productivity—trade was just not that important.

When Krugman first began writing articles for popular publications, in the mid-nineties, Bill Clinton was in office, and Krugman thought of the left and the right as more or less equal in power. Thus, there was no pressing need for him to take sides—he would shoot down idiocy wherever it presented itself, which was, in his opinion, all over the place.

Steampunk tries to capture that Edwardian moment when steam power still ruled

Stefany Anne Golberg in The Smart Set:

ScreenHunter_03 Mar. 02 10.11 The aesthetic movement Steampunk wants to bring the wonder back into our relationship with machines. Its tack is to fully embrace (and affect) an Edwardian orientation to the world. Though Steampunk has been a growing cultural trend for a few decades, it really came into its own in the aughts and is now a full-fledged phenomenon. Steampunks dress like the Wright Brothers and Arctic explorers. They write alternate history fantasies in which alien clones ride around in dirigibles by the light of gas lamps. Steampunks are fascinated by mechanics, and Steampunk art, jewelry, and fashion often involve gears, wheels, pulleys, and, of course, steam: a laptop computer fused with a rickety typewriter; an arcade game redesigned to look like a mini-submarine. What most defines Steampunk as a culture, however, is attitude. The “punk” in Steampunk confronts technology's alienating qualities with messy DIY defiance. The “steam” (besides its literal connotations) is almost like another word for magic: brute, utilitarian contraptions powered by clouds, and breath — ephemeral energy.

Steampunk tries to capture that Edwardian moment when steam power still ruled and the romance of technology lay precisely in the line it toed between destruction and possibility. Equally fascinated by flying machines and trench warfare, Steampunk is both optimistic and nihilistic. I like to think of this attitude as Gleehilism. It's this Gleehilism that makes Steampunk one of the defining aesthetic movements of the early 21st century.

Daniel Kahneman: The riddle of experience vs. memory

“Widely regarded as the world’s most influential living psychologist, Daniel Kahneman won the Nobel in Economics for his pioneering work in behavioral economics.”

“Using examples from vacations to colonoscopies, Nobel laureate and founder of behavioral economics Daniel Kahneman reveals how our “experiencing selves” and our “remembering selves” perceive happiness differently. This new insight has profound implications for economics, public policy — and our own self-awareness.”

Furious backlash from Simon Singh libel case puts chiropractors on ropes

Martin Robbins in The Guardian:

Chiropractor-manipulates--002 As the British Chiropractic Association's battle with Simon Singh continues to work its way through the legal system, chiropractors are counting the financial costs of a major backlash resulting from a libel action that has left the Lord Chief Justice “baffled”. What was originally a dispute between the BCA and one science writer over free speech has become a brutally effective campaign to reform an entire industry.

A staggering one in four chiropractors in Britain are now under investigation for allegedly making misleading claims in advertisements, according to figures from the General Chiropractic Council.

The council, which is responsible for regulating the profession and has 2,400 chiropractors on its books, informs me that it has had to recruit six new members of staff to deal with a fifteenfold increase in complaints against its members – from 40 a year to 600. While it declined to comment directly on the costs inflicted by the reaction to the BCA's actions, it is clear that a six-figure sum will be involved for the extra staffing costs alone, to which will have to be added the considerable costs of any misconduct hearings.
