Bush Saying "Fair Trial" Doesn't Make it True.

Saddam Hussein had barely stopped dangling when George W. Bush revved up the lie machine.

His idea of justice is “rough justice” or “frontier justice” or “the King’s justice,” whereby if he calls it justice, it is justice. If he deems it a fair trial, it is a fair trial.

“Today, Saddam Hussein was executed after receiving a fair trial,” he said in the very first sentence of his rushed statement, a claim Bush repeated, in case you missed it, in his second sentence and then again in his third.

But Bush, as powerful as he is, does not make a trial fair by declaring it fair.

The world’s two leading human rights organizations, Amnesty International and Human Rights Watch, both came to a different conclusion from Bush.

Amnesty International called the trial “deeply flawed and unfair.” It was “a shabby affair,” said Malcolm Smart, director of Amnesty International’s Middle East and North Africa Program.

Amnesty International cited “the grave nature of the flaws,” which included the following:

“The court failed to take adequate measures to ensure the protection of witnesses and defense lawyers, three of whom were assassinated during the course of the trial,” it said. “Saddam Hussein was also denied access to legal counsel for the first year after his arrest, and complaints by his lawyers throughout the trial relating to the proceedings do not appear to have been adequately answered by the tribunal.”

Nor were they adequately answered by the appeals court.

“The execution appeared a foregone conclusion, once the original verdict was pronounced, with the Appeals Court providing little more than a veneer of legitimacy for what was, in fact, a fundamentally flawed process,” said Smart.

Human Rights Watch concurred.

It called Saddam’s trial “deeply flawed,” and termed his execution “a significant step away from respect for human rights and the rule of law in Iraq.”

Among the “serious flaws” that Human Rights Watch noted: “failures to disclose key evidence to the defense, violations of the defendants’ right to question prosecution witnesses, and the presiding judge’s demonstrations of bias.”

Yes, Saddam Hussein was a mass murderer on a colossal scale. But even he deserved a fair trial.

The flaws didn’t bother Bush, though, who crowed about “bringing Saddam Hussein to justice.”

This is one of Bush’s favorite constructions. Whenever the United States kills someone Bush believes is a terrorist, he says that person has been “brought to justice,” whether that person was killed by a bomb, by an extrajudicial killing, or by a kangaroo court, as in the case of Saddam.

In his 2002 State of the Union address, Bush vowed to “bring terrorists to justice.”

In his 2003 State of the Union address, he said, “One by one, the terrorists are learning the meaning of American justice.”

When U.S. troops killed Saddam’s sons Uday and Qusay, Bush said they were “brought to justice.”

But is this truly “the meaning of American justice”?

What Bush reveres is not our great system of jurisprudence, which guarantees due process and habeas corpus. He’s proven that with his insistence on the right to torture and with his Military Commissions Act, which allows the use of evidence that was beaten out of the defendant and which deprives any noncitizen whom Bush deems an enemy combatant of the right even to see a judge.

Bush has no appreciation of “the meaning of American justice.”

His idea of justice is “rough justice” or “frontier justice” or “the King’s justice,” whereby if he calls it justice, it is justice. If he deems it a fair trial, it is a fair trial.

Executing Saddam Hussein

I am probably in the minority, but I find the execution of Saddam Hussein troublesome, knowing full well the savage, murderous environment he created for so many people. There is no doubt he will go down in history as one of the most brutal dictators that ever lived. Yet, watching him take his final steps to meet his executioners disturbs me on some level. I don't see how the premeditated execution of a man, any man, heinous as he may be, is incommensurable with what he is being executed for.

The irony is many of the people who fight for capital punishment are the same ones claiming they trust God implicitly... yet they cannot trust God enough to decide how and when the fate, of what they believe He created, should be.

Who gives any man the right to play God?

Only 10% of All Charitable Deductions Go to Help Poor.




Lots of charitable dollars — especially from the wealthy, who have the most to donate — are going to culture palaces: to the operas, art museums, symphonies, and theaters where they spend much of their leisure time. And to the universities they once attended and expect their children to attend, perhaps with the help of what's known as affirmative action for "legacies."

These aren't really charitable contributions. They're more like investments in the lifestyles the wealthy already enjoy and want their children to have too. They're also investments in prestige, especially if they result in the family name engraved on the new wing of the art museum or symphony hall.

Now it's their business how they donate their money. But not entirely, because, you see, charitable donations are deductible from income taxes.

This year, the U.S. Treasury will be getting about $40 billion less than it would if the tax code didn't allow charitable deductions. By the way, the government now spends less than $40 billion a year on Temporary Assistance for Needy Families, which is what's left of welfare.

I can see why a contribution to, say, the Salvation Army should be eligible for a charitable tax deduction. It's helping the poor. But why, exactly, should a contribution to the Guggenheim Museum or Harvard University?

Not long ago, New York City's Lincoln Center had a gala dinner supported by the charitable contributions of the leaders of the hedge fund industry, some of whom will be receiving billion-dollar bonuses in the next few weeks. I may be missing something here, but this doesn't strike me as charity. I mean, poor New Yorkers don't often attend concerts at the Lincoln Center.

It turns out, in fact, that only an estimated 10 percent of all charitable deductions this year will be directed at the poor.


At a time in our nation's history when the number of needy continue to rise, when government doesn't have the money to do what's necessary, and when America's very rich are richer than ever, we should revise the tax code.

Limit the charitable deduction to real charities.

And have a happy holiday.

Hold Hands With Your Spouse!


Washington, Dec 19: A new study has found that all women need to lower their stress levels is a strong and happy marriage.

A team of researchers led by James A. Coan, a University of Virginia neuroscientist has found that women under stress who hold their husbands' hands show signs of immediate relief, which can clearly be seen on their brain scans.

Coan, an assistant professor in the U.Va. Neuroscience Graduate Program and the Department of Psychology, and his team conducted a study involving several couples who rated themselves as highly satisfied with their marriages.

As a part of their study, the researchers designed a functional MRI (magnetic resonance imaging) study in which 16 married women were subjected to the threat of a very mild electric shock while they by turns held their husband's hand, the hand of a stranger (male) or no hand at all.

They found that the MRI was able to show how these women's brains responded to this handholding while in a threatening situation.

The researchers noted a large decrease in the brain response to threat as a function of spouse handholding, and a limited decrease in this response as a function of stranger handholding.

Moreover, spouse handholding effects varied as a function of marital quality, with women in the very highest quality marriages benefiting from a very powerful decrease in threat-related brain activity, including a strong decrease in the emotional (affective) component of the brain's pain processing circuits.

"This is the first study of the neurological reactions to human touch in a threatening situation, and the first study to measure how the brain facilitates the health-enhancing properties of close social relationships," said Dr. Coan.

Laughter is Contagious


Laughter is truly contagious, and now, scientists studying how our brain responds to emotive sounds believe they understand why.

Researchers at University College London (UCL) and Imperial College London have shown that positive sounds such as laughter or a triumphant "woo hoo!" trigger a response in the listener's brain. This response occurs in the area of the brain that is activated when we smile, as though preparing our facial muscles to laugh. The research, funded by the Wellcome Trust, Action Medical Research and the Barnwood House Trust, is published today in the Journal of Neuroscience.

Led by Dr Sophie Scott, a Wellcome Trust Senior Research Fellow at the Institute of Cognitive Neuroscience, UCL, the research team played a series of sounds to volunteers while measuring their brain's response using an fMRI scanner. Some of the sounds were positive, such as laughter or triumph, while others were unpleasant, such as screaming or retching. All of the sounds triggered a response in the volunteer's brain in the premotor cortical region, which prepares the muscles in the face to respond accordingly, though the response was greater for positive sounds, suggesting that these were more contagious than negative sounds. The researchers believe this explains why we respond to laughter or cheering with an involuntary smile.

Substance Found in Soy Helps to Relieve MS Symptoms

A natural substance from soy appears to have amazing restorative powers when given to animals with a multiple sclerosis (MS.

Neurologists at Jefferson Medical College found, using an animal model of MS, that giving doses of a substance called Bowmann-Birk Inhibitor Concentrate (BBIC) dramatically improved the animals’ ability to move and walk. The scientists, led by A. M. Rostami, M.D., Ph.D., professor and chair of the Department of Neurology at Jefferson Medical College of Thomas Jefferson University and the Jefferson Hospital for Neuroscience in Philadelphia, say the treatment’s effects may be useful in conjunction with more mainstream therapies such as beta-interferon in helping patients with MS. They report their findings December 12, 2006 in the journal Multiple Sclerosis.

MS, one of the most common neurological diseases affecting young adults, is thought to be an autoimmune disease (in which the body attacks its own tissue) affecting the central nervous system (CNS). In MS, the myelin coating of nerve fibers becomes inflamed and scarred. As a result, “messages” cannot be sent through the nervous system.

Dr. Rostami, who is also director of the Neuroimmunology Laboratory in the Department of Neurology at Jefferson Medical College, and his group used an animal model of experimental autoimmune encephalomyelitis (EAE), which mimics MS, to investigate BBIC’s potential immune system-suppressing properties. BBIC inhibits proteases, enzymes that play important roles in the inflammation and demyelination processes that are at the heart of MS. It has been used for other conditions, notably precancerous conditions in the mouth.

He and his co-workers compared two groups of animals with EAE. One group received BBIC, while the other received only an inert substance. “Animals that received BBIC were able to walk while those that didn’t get the drug were not,” he says. He notes that the animals aren’t cured but can walk with some limp or weakness. “The results are promising because this is a safe, natural compound from soybean and is given orally.”

Further analysis revealed that the central nervous systems of animals that received BBIC showed “significantly less inflammation and demyelination” than those that didn’t receive the therapy. “It’s the first time that BBIC has been used in an EAE model and has shown significant disease suppression, and we hope it can eventually be used in humans,” says Dr. Rostami. His group’s next step is to design clinical trials in humans.

The scientists are not sure how BBIC works in multiple sclerosis, but they theorize that it suppresses the immune response to some extent, in addition to inhibiting proteases. Dr. Rostami sees BBIC as being used as a single therapy or in conjunction with other drugs in treating MS. He notes that because current therapies for MS involve injecting drugs such as interferon and copaxane, one goal is to develop an oral agent. BBIC could be given by pill daily.

Over 400,000 Americans acknowledge having MS, though nearly one million Americans may be living with the disease. Symptoms can include fatigue, loss of coordination, muscle weakness, numbness, inability to walk or use hands and arms, pain, vision problems, slurred speech and bladder/bowel dysfunction.

Male Circumcision Reduces HIV Risk

More than 90 percent of HIV infections in adults result from heterosexual intercourse.

A University of Illinois at Chicago study has been stopped early due to preliminary results indicating that medical circumcision of men reduces their risk of acquiring HIV during heterosexual intercourse by 53 percent.

The study's independent Data Safety and Monitoring Board met Dec. 12 to review the interim data. Based on the board's review, the National Institutes of Health halted the trial and recommended that all men enrolled in the study who remain uncircumcised be offered circumcision.

"Circumcision is now a proven, effective prevention strategy to reduce HIV infections in men," said Robert Bailey, professor of epidemiology in the UIC School of Public Health and principal investigator of the study.

The clinical trial, funded by the National Institute of Allergy and Infectious Diseases and the Canadian Institute of Health Research, enrolled 2,784 HIV negative, uncircumcised men between 18 and 24 years old in Kisumu, Kenya.

Half the men were randomly assigned to circumcision, half remained uncircumcised. All men enrolled in the study received free HIV testing and counseling, medical care, tests and treatment for sexually transmitted infections, condoms and behavioral risk counseling for 24 months.

Study results show that 22 of the 1,393 circumcised men in the study contracted HIV, compared to 47 of the 1,391 uncircumcised men. In other words, circumcised men had 53 percent fewer HIV infections than uncircumcised men.

Until now, public health organizations have not supported circumcision as a method of HIV prevention due to a lack of randomized controlled trials.

"With these findings, the evidence is now available for donor and normative agencies, like WHO and UNAIDS, to actively promote circumcision in a safe context and along with other HIV prevention strategies," Bailey said.

"Circumcision cannot be a stand-alone intervention. It has to be integrated with all the other things that we do to prevent new HIV infections, such as treating sexual transmitted diseases and providing condoms and behavioral counseling," Bailey said. "We can't expect to just cut off a foreskin and have the guy go on his merry way without additional tools to fight against getting infected."

Opponents of circumcision have speculated that circumcised men may feel they are not at risk of contracting HIV and may be more likely to engage in risky behavior. The Kenya study suggests that circumcision did not increase risky behavior among circumcised or uncircumcised men, according to Bailey.

"Both uncircumcised and circumcised men are reducing their sexual risk behavior," he said, "which indicates that our counseling is doing some good."

The study also evaluated the safety of circumcision in a community health clinic with specially trained practitioners. There were no severe or lasting complications from circumcision. However, 1.7 percent of surgeries resulted in mild complications, such as bleeding or infection.

Bailey said that promoting circumcision in Africa must be done in conjunction with proper technical training and medical tools, equipment and supplies necessary to perform large numbers of circumcisions safely.

"Already, there are large numbers of boys and young men who are seeking circumcision in areas of Africa where men are not traditionally circumcised," he said. "The danger is that unqualified practitioners will fill a niche by providing circumcision, but with much higher complication rates."

An estimated 30 million people in Africa are infected with HIV/AIDS and more than 90 percent of HIV infections in adults result from heterosexual intercourse. In Kisumu, the third-largest city in Kenya, an estimated 26 percent of uncircumcised men are HIV infected by age 25.

"This study will likely not have a large impact on the incidence of HIV/AIDS in the United States or Europe where heterosexual transmission of HIV is low compared with areas like sub-Saharan Africa and parts of Asia," Bailey said. "However, there are other proven health benefits of circumcision, including better hygiene, fewer urinary tract infections, and less risk of cervical cancer in the partners of circumcised men."

The armamentarium of HIV prevention strategies is very small, according to Bailey. The only other strategy proven effective is the use of antiretroviral drugs to reduce transmission from mother to child.

If a significant proportion of men in a population get circumcised, it will have an enormous impact on preventing HIV infection in men, as well as reducing infections in women, Bailey said.

Co-investigators of the study include Stephen Moses and Ian Maclean at the University of Manitoba, Jekoniah Ndinya-Achola at the University of Nairobi, Corette Parker at Research Triangle International, Kawango Agot at UNIM Project, John Krieger at University of Washington, and Richard Campbell at UIC.

During the past two decades, more than 40 observational epidemiological studies and one previous clinical trial have reported an association between male circumcision and a reduced risk of HIV infection.

Top Quark Detected

RIVERSIDE, Calif. – A group of 50 international physicists, led by UC Riverside’s Ann Heinson, has detected for the first time a subatomic particle, the top quark, produced without the simultaneous production of its antimatter partner – an extremely rare event. The discovery of the single top quark could help scientists better explain how the universe works and how objects acquire their mass, thereby assisting human understanding of the fundamental nature of the universe.

The heaviest known elementary particle, the top quark has the same mass as a gold atom and is one of the fundamental building blocks of nature. Understood to be an ingredient of the nuclear soup just after the Big Bang, today the top quark does not occur naturally but must be created experimentally in a high-energy particle accelerator, an instrument capable of recreating the conditions of the early universe.

“We’ve been looking for single top quarks for 12 years, and until now no one had seen them,” said Heinson, a research physicist in the Department of Physics and Astronomy. “The detection of single top quarks – we detected 62 in total – will allow us to study the properties of top quarks in ways not accessible before. We are now able to study how the top quark is produced and how it decays. Do these happen as theory says they should? Are new particles affecting what we see? We're now better positioned to answer such questions.”

The detection of the top quark on its own was the outcome of a time-consuming process involving hundreds of scientists who constitute the “DZero” collaboration, a team of experimenters studying the top quark in particle collisions.

For its part, Heinson’s team first collected data from collision experiments conducted between 2002 and 2005 at the Tevatron Collider, the world’s highest energy particle accelerator that is comprised of a four-mile long underground ring at the Department of Energy’s Fermi National Accelerator Laboratory in Batavia, Ill. The collisions recorded were those between protons and antiprotons (the antimatter counterparts of protons).

Next, Heinson and her colleagues analyzed the record of high-energy collisions using powerful computers that helped the researchers determine which types of particles resulted from the collisions.

When a proton smashes head-on into an antiproton at nearly the speed of light, the collision occasionally produces a top quark. This heavy, unstable particle exists, however, for only a tiny fraction of a second before it decays into lighter particles, thereby complicating its detection. Physicists therefore must look at the top quark's descendents to identify it.

“We detected the top quark using the electronic signature of its decay products,” said Heinson, the primary author of a research paper on the single top quark’s detection that her group will submit to Physical Review Letters. “We measured the position of charged particles using a silicon vertex detector, which is an instrument – first encountered by the particles after the collision – that can precisely reconstruct the trajectories of charged particles. Since theory predicts single top quark production, we knew what to look for. It was extremely difficult, however, to find.”

Brains Can Recover From Alcoholism To a Degree.

New research reveals the brain's capacity to regenerate -- however, the sooner alcoholics abstain from drinking the more they may recover

The findings, published today (18 December 2006) in the online edition of the journal Brain [1], used sophisticated scanning technology and computer software to measure how brain volume, form and function changed over six to seven weeks of abstinence from alcohol in 15 alcohol dependent patients (ten men, five women).

The researchers from Germany, the UK, Switzerland and Italy measured the patients’ brain volume at the beginning of the study and again after about 38 days of sobriety, and they found that it had increased by an average of nearly two per cent during this time. In addition, levels of two chemicals, which are indicators for how well the brain’s nerve cells and nerve sheaths are constituted, rose significantly. The increase of the nerve cell marker correlated with the patients performing better in a test of attention and concentration. Only one patient seemed to continue to lose some brain volume, and this was also the patient who had been an alcoholic for the longest time.

The leader of the research, Dr Andreas Bartsch from the University of Wuerzburg, Germany, said: "The core message from this study is that, for alcoholics, abstinence pays off and enables the brain to regain some substance and to perform better. However, our research also provides evidence that the longer you drink excessively, the more you risk losing this capacity for regeneration. Therefore, alcoholics must not put off the time when they decide to seek help and stop drinking; the sooner they do it, the better."

Dr Bartsch, who is senior neuroradiology resident and head of the structural and functional MR-imaging laboratory of the Department of Neuroradiology at the University of Wuerzburg, said the study was one of the first to be able to integrate data that showed how the brain regained volume and function early on, once alcoholics, who had no complicating factors, had stopped drinking alcohol. It was carried out in collaboration with colleagues from the University of Oxford’s Centre for Functional Magnetic Resonance Imaging of the Brain (FMRIB) and from the University of Siena’s Institute of Neurological and Behavioural Sciences.

The patients’ brains were scanned using magnetic resonance imaging (MRI) and proton MR-spectroscopy upon admission and after short-term sobriety. Only the patients that managed to abstain from alcohol without receiving any psychotherapeutic medication were included in the study, and those with secondary alcohol-induced disorders, as well as heavy cigarette smokers (more than 10 cigarettes a day), were excluded. Ten healthy volunteers (six men, four women), matched for age and gender, were recruited as controls for the study. The data were analysed and evaluated using FSL, a sophisticated software package developed at the Oxford FMRIB Centre, and LCModel (a computer program that analyses spectroscopy data) to give estimates of changes to brain volume, form (morphology), metabolism and function.

The technology enabled the researchers to superimpose the images of the patients’ brains upon follow-up on to the images of the brains at the start of the study so that they could see any morphological changes. They also measured how levels of various chemicals, including N-acetylaspartate (NAA) and choline, changed between the two time points. NAA can indicate how intact the brain’s nerve cells are (i.e. it is a metabolic marker of neuronal integrity), while choline provides hints at how cell membranes are being broken down and repaired.

In addition, the neuropsychological performance of the patients was tested at the beginning and end of the study, using a specific test (the d2-test) that primarily measures attention and concentration [2].

Dr Bartsch said: "After short-term sobriety of less than two months, we found that brain volume had increased by an average of nearly two per cent (1.82%), with a range of -0.19 to 4.32%. Only the one patient with the longest history of alcohol dependence (25 years) had a slightly reduced brain volume (-0.19%), but that value is within the margin of measurement error. Volumetric brain recovery was signified by the patients’ brains expanding beyond their previous limits, with an outward brain edge shift for the outer regions and an inward shift for the inner ones.

"In addition, on average across all the patients, cerebellar choline levels increased by about 20%, while levels of NAA in the cerebellar and frontal region of the brain and frontal choline significantly increased by about 10%. Brain volume regeneration correlated with the percentages increase in choline, indicating that volume regain is driven primarily by rising choline levels, while the more the NAA recovered, the better the patients performed on the d2-test."

There were no significant changes in the controls.

Dr Bartsch and his colleagues were confident that the increase in brain volume and form was not simply due to rehydration of the brain, as concentrations of choline and NAA increased even when water levels and other metabolites did not change significantly.

"Our results indicate that early brain recovery through abstinence does not simply reflect rehydration. Instead, the adult human brain, and particularly its white matter, seems to possess genuine capabilities for re-growth. Our findings show the ways that the brain can recover from the toxic insults of chronic alcoholism and substantiate the early measurable benefits of therapeutic sobriety. However, they also suggest that prolonged dependence on alcohol may limit rapid recovery from white matter brain injury.

"Modern neuroimaging enables us to monitor morphological, metabolic and other functional brain changes. Usually this has been applied to evaluate the degree and speed of brain degeneration in illnesses such as Alzheimer’s disease or multiple sclerosis. Here, we show that neuroimaging can also demonstrate and quantify brain regeneration in substance and function. Data analysis is crucial to these endeavours, and modern software such as the tools delivered by the Image Analysis Group at the FMRIB centre in Oxford provides us with the utilities necessary for such studies. For instance, I am able to inform a specific patient how much exactly his or her brain has benefited from sobriety and, as a clinician, I believe this may be a very supportive part of their treatment," he concluded.

In an accompanying commentary, Professor Graeme Mason, wrote that the study was important not just because it unified several previously separate lines of research but because it might give doctors the tools to motivate their alcohol-dependent patients to stay sober.

"Doctors treating or studying alcoholism should be made aware of the research of Dr Bartsch because it may provide a motivational tool that is a broad set of concrete, tangible, and rapid benefits of sobriety: cognition, chemistry and brain volume," wrote the associate professor of diagnostic radiology and psychiatry at Yale University. Prof Mason believed this was a particularly valuable contribution of the study because "patients often become discouraged from the physical and cognitive difficulties of achieving and maintaining sobriety."

Reading Shakespeare Excites Your Brain


Shakespeare uses a linguistic technique known as functional shift that involves, for example using a noun to serve as a verb. Researchers found that this technique allows the brain to understand what a word means before it understands the function of the word within a sentence. This process causes a sudden peak in brain activity and forces the brain to work backwards in order to fully understand what Shakespeare is trying to say.

Professor Philip Davis, from the University’s School of English, said: “The brain reacts to reading a phrase such as ‘he godded me’ from the tragedy of Coriolanus, in a similar way to putting a jigsaw puzzle together. If it is easy to see which pieces slot together you become bored of the game, but if the pieces don’t appear to fit, when we know they should, the brain becomes excited. By throwing odd words into seemingly normal sentences, Shakespeare surprises the brain and catches it off guard in a manner that produces a sudden burst of activity - a sense of drama created out of the simplest of things.”

Experts believe that this heightened brain activity may be one of the reasons why Shakespeare’s plays have such a dramatic impact on their readers.

Professor Neil Roberts, from the University’s Magnetic Resonance and Image Analysis Research Centre, (MARIARC), explains: “The effect on the brain is a bit like a magic trick; we know what the trick means but not how it happened. Instead of being confused by this in a negative sense, the brain is positively excited. The brain signature is relatively uneventful when we understand the meaning of a word but when the word changes the grammar of the whole sentence, brain readings suddenly peak. The brain is then forced to retrace its thinking process in order to understand what it is supposed to make of this unusual word.”

Professor Roberts and Professor Davis together with Dr Guillaune Thierry, from the University of Wales, Bangor, monitored 20 participants using an electroencephalogram (EEG) as they read selected lines from Shakespeare’s plays.

In this initial test electrodes were placed on the subject’s scalp to measure brain responses.

Professor Roberts said: “EEG gives graph-like measurements and when the brain reads a sentence that does not make semantic sense it registers what we call a N400 effect – a negative wave modulation. When the brain reads a grammatically incorrect sentence it registers a P600 effect – an effect which continues to last after the word that triggered it was first read.”

Researchers also found that when participants read the word producing the functional shift there was no N400 effect indicating that the meaning was accepted but a P600 effect was observed which indicates a positive re-evaluation of the word. The team is now using magnetoencephalography (MEG) and functional magnetic resonance imaging (FMI) to test which areas of the brain are most affected and the kind of impact it could have in maintaining healthy brain activity.

Professor Davis added: “This interdisciplinary work is good for brain science because it offers permanent scripts of the human mind working moment-to-moment. It is good for literature as it illustrates primary human thinking. Through the two disciplines, we may discover new insights into the very motions of the mind.”

Obesity Cured by Antibiotics??

Dec. 20, 2006 -- A link between obesity and the microbial communities living in our guts is suggested by new research at Washington University School of Medicine in St. Louis. The findings indicate that our gut microbes are biomarkers, mediators and potential therapeutic targets in the war against the worldwide obesity epidemic.

In two studies published this week in the journal Nature, the scientists report that the relative abundance of two of the most common groups of gut bacteria is altered in both obese humans and mice. By sequencing the genes present in gut microbial communities of obese and lean mice, and by observing the effects of transplanting these communities into germ-free mice, the researchers showed that the obese microbial community has an increased capacity to harvest calories from the diet.

"The amount of calories you consume by eating, and the amount of calories you expend by exercising are key determinants of your tendency to be obese or lean," says lead investigator Jeffrey Gordon, M.D., director of the Center for Genome Sciences and the Dr. Robert J. Glaser Distinguished University Professor. "Our studies imply that differences in our gut microbial ecology may determine how many calories we are able to extract and absorb from our diet and deposit in our fat cells."

That is, not every bowl of cereal may yield the same number calories for each person. People could extract slightly more or slightly less energy from a serving depending upon their collection of gut microbes. "The differences don't have to be great, but over the course of a year the effects can add up," Gordon says.

Trillions of friendly microbes reside in the intestine, where they help to digest food that the body can't on its own, such as the complex sugars found in grains, fruits and vegetables. As part of the digestive process, the microbes break down nutrients to extract calories that can be stored as fat.

The researchers focused on two major groups of bacteria - the Bacteroidetes and the Firmicutes - that together make up more than 90 percent of microbes found in the intestines of mice and humans. In an earlier study, they compared genetically obese mice and their lean littermates. The obese mice had 50 percent fewer Bacteroidetes and proportionately more Firmicutes. Moreover, the differences were not due to a bloom of one species in the Firmicutes or a diminution of a single or a few species of Bacteroidetes: virtually all members of each group were altered.

In one of this week's Nature articles, Ruth Ley, Ph.D., a microbial ecologist in Gordon's group, reports on her investigation into whether these findings also held true among obese humans. She followed 12 obese patients at a Washington University weight loss clinic over a one-year period. Half the patients were on a low-calorie, low-fat diet and half were on a low-calorie, low carbohydrate diet.

At the outset of the study, the obese patients had the same type of depletion of Bacteroidetes and relative enhancement of Firmicutes as the obese mice. As the patients lost weight, the abundance of the Bacteroidetes increased and the abundance of Firmicutes decreased, irrespective of the diet they were on. Moreover, not one particular species of Bacteroidetes but the entire group increased as patients lost weight.

In a companion paper in the same journal, Peter Turnbaugh, a Ph.D. student in Gordon's lab, compared the genes present in the gut microbial communities of the obese and lean mice using the newest generation of massively parallel DNA sequencers.

The results of these so-called comparative metagenomic studies revealed that the obese animals' microbial community genome (microbiome) had a greater capacity to digest polysaccharides, or complex carbohydrates. By transferring the gut microbial communities of obese and lean mice to mice that had been raised in a sterile environment (germ-free animals), he confirmed that the obese microbial community prompted a significantly greater gain in fat in the recipients.

Gordon notes that these findings represent steps in a long journey designed to understand the contributions of our microbial self to our health. "Our microbial cells outnumber our human cells by as much as 10 fold and, and they may contain 100 times more genes than our own human genome," Gordon says.

These studies raise a number of questions, according to Gordon. "Are some adults predisposed to obesity because they 'start out' with fewer Bacteroidetes and more Firmicutes in their guts?" he asks. "Can features of a reduced Bacteroidetes-Firmicutes enriched microbial community become part of our definition of an obese state or a diagnostic marker for an increased risk for obesity? And can we intentionally manipulate our gut microbial communities in safe and beneficial ways to regulate energy balance?"

Abnormal Proteins Linked to Schizophrenia Found in Body Tissue

A new study suggests biochemical changes associated with schizophrenia aren't limited to the central nervous system and that the disease could have more encompassing effects throughout the body than previously thought. The findings, scheduled for publication in the January 2007 issue of the American Chemical Society's Journal of Proteome Research, could lead to better diagnostic testing for the disease and could help explain why those afflicted with it are more prone to type II diabetes, cardiovascular diseases and other chronic health problems.

Researcher Sabine Bahn, M.D., Ph.D., and her colleagues at Cambridge University in England and the University of Cologne in Germany, detected abnormal proteins linked to schizophrenia in the liver and red blood cells of people who have the disorder. It is the first time the same altered proteins have been detected both within brain tissue as well as in non-brain tissue, according to Bahn.

In time, Bahn says, these protein "biomarkers" could be used to trace the progression of the disease throughout the body.

"If changes in the rest of the body can be observed, and if these changes reflect what is going wrong in the brain, we can use these (findings) to learn about the cellular dysfunction that causes schizophrenia and this will allow us to develop better drugs and diagnostics," Bahn says.

About 1 percent of the world's population -- including 2.4 million Americans -- has schizophrenia, a complex and puzzling mental illness that can lead to delusions, hallucinations and disordered thinking. It is one of the world's most common causes of psychosis, according to Bahn. Since it was first described more than 100 years ago, scientists have made little progress in unraveling the causes of the disease, and no definitive test is available to diagnosis it, she says.

"We desperately need a better understanding of this illness. It is, however, difficult to study the disease, as the brain can't easily be investigated. We can't take multiple biopsies from patients to look at the disease-related changes," Bahn says. "We need a new concept."

While most scientists investigating the disease believe it only affects the brain, Bahn notes that researchers have long known that people who have schizophrenia are at higher risk than the general population for a number of chronic diseases. Some evidence suggests these health problems might be somehow tied to schizophrenia, she adds, but most studies have been inconclusive. Bahn's latest discovery could help bridge this gap.

Recently, Bahn and her colleagues discovered a set of abnormal proteins in post-mortem brains of people who had schizophrenia. In this new study, they sought to detect similarly altered proteins in other organs and tissues of individuals living with the disease. After looking at thousands of proteins, they found that people with schizophrenia had 14 liver proteins and eight red blood cell proteins that were significantly altered compared to individuals who didn't have the disease. These altered proteins were strikingly like those found in the post-mortem brains.

Several of these abnormal proteins appear to promote oxidative stress and disrupt energy metabolism in cells, Bahn says. She theorizes that schizophrenia is caused, at least in part, by these two problems. In her earlier work, for instance, Bahn found evidence that schizophrenic brains might have difficulty producing or using energy properly and are more susceptible to cell-damaging free radicals than healthy brains. The new findings, she says, suggest that the same sort of energy starvation, increased free-radical damage cycle could be occurring in other tissue and, in addition to schizophrenia, possibly be contributing to the onset of other chronic diseases.

More Than a Few Bad Apples.

Published: December 20, 2006

Ever since the world learned of the lawless state of American military prisons in Iraq, the administration has hidden behind the claim that only a few bad apples were brutalizing prisoners. President Bush also has dodged the full force of public outrage because the victims were foreigners, mostly Muslims, captured in what he has painted as a war against Islamic terrorists bent on destroying America.

This week, The Times published two articles that reminded us again that the American military prisons are profoundly and systemically broken and that no one is safe from the summary judgment and harsh treatment institutionalized by the White House and the Pentagon after 9/11.

On Monday, Michael Moss wrote about a U.S. contractor who was swept up in a military raid and dumped into a system where everyone is presumed guilty and denied any chance to prove otherwise.

Donald Vance, a 29-year-old Navy veteran from Chicago, was a whistle-blower who prompted the raid by tipping off the F.B.I. to suspicious activity at the company where he worked, including possible weapons trafficking. He was arrested and held for 97 days — shackled and blindfolded, prevented from sleeping by blaring music and round-the-clock lights. In other words, he was subjected to the same mistreatment that thousands of non-Americans have been subjected to since the 2003 invasion.

Even after the military learned who Mr. Vance was, they continued to hold him in these abusive conditions for weeks more. He was not allowed to defend himself at the Potemkin hearing held to justify his detention. And that was special treatment. As an American citizen, he was at least allowed to attend his hearing. An Iraqi, or an Afghani, or any other foreigner, would have been barred from the room.

This is not the handiwork of a few out-of-control sadists at Abu Ghraib. This is a system that was created and operated outside American law and American standards of decency. Except for the few low-ranking soldiers periodically punished for abusing prisoners, it is a system without any accountability.

Yesterday, David Johnston reported that nearly 20 cases in which civilian contractors were accused of abusing detainees have been sent to the Justice Department. So far, the record is perfect: not a single indictment.

Administration officials said that prosecutors were hobbled by a lack of evidence and witnesses, or that the military’s cases were simply shoddy. This sounds like another excuse from an administration that has papered over prisoner abuse and denied there is any connection between Mr. Bush’s decision to flout the Geneva Conventions and the repeated cases of abuse and torture. We hope the new Congress will be more aggressive on this issue than the last one, which was more bent on preserving the Republican majority than preserving American values and rights. The lawless nature of Mr. Bush’s war on terror has already cost the nation dearly in terms of global prestige, while increasing the risks facing every American serving in the military.

Put Away Your Flags and Bumper Stickers....

...this is the stuff we need to be concentrating on, making it as easy as we can for our soldiers who get paid very little to do what most of us could never imagine.

A backpack that reduces the forces on your body when carrying heavy loads could help prevent injury, allow soldiers to carry more equipment and even speed up the response time of emergency services, its designer claims.

When people walk, they tend to raise and lower their bodies by between 5 centimetres and 7 cm with each step. If they are carrying a backpack, the extra load must also be raised by the same amount and this puts extra strain on the body.

Now Larry Rome, a muscle physiologist at the University of Pennsylvania in Philadelphia, US, has worked out a way to reduce these forces by fundamentally changing the design of the backpack.

His new design consists of a frame which a person wears like an ordinary backpack. However, the load is suspended from the frame by elasticated bungee cords which lengthen as the wearer takes a stride, thereby keeping the load at a constant height. A video (AVI format, 6mb) of the backpack is available here.

“By suspending the load, you knock out 86% of this extra force, making it comfortable to run with a heavy load,” says Rome, who has published his results in the journal Nature. The principle is similar to that used by traditional Asian merchants who carry their wares using flexible bamboo poles.
Pile on the pounds

Rome says being able to run comfortably while carrying a heavy load could make life easier for many groups of people. He points out that children often suffer bone and muscle injuries from carrying heavy schoolbooks and believes his backpack could help. And first responders in the emergency services also often have to carry heavy loads.

The backpack also reduces the total energy needed to carry heavy loads by around 40%. That may make it possible for people such as soldiers to carry heavier loads. “You can carry 60 lbs in our backpack for the same metabolic cost as 48 lbs in a normal backpack, hence you can carry 12 lbs for free,” he says.

The load can also be locked in place to function as a conventional backpack, which might be useful when the wearer is not walking in a rhythmic way, Rome suggests, such as when crossing a stream.
Military use

Rome was initially approached by the US Office of Naval Research to design a backpack that could generate power from the wearer’s body movements (see Backpack generates a powerful punch). The military had found that soldiers’ ever increasing reliance on electronic equipment such as GPS systems, night-vision sights and computers meant they were replacing food and medical equipment in their backpacks with batteries. The ONR was looking for a way for soldiers to generate their own power on the move.

“My knowledge of biomechanics made me realise that the way people were trying to do it – with heel strike devices – was not the best way,” says Rome. Instead he came up with an electricity-generating backpack in which a sliding action between the load and the backpack frame generates power.

He suspected that the mechanism also reduced the forces on the body and further development of the idea led to the new ergonomic backpack. Rome has set up a company called Lightning Packs to bring the backpack to market.

Others agree that the work will have a significant benefit. Rodger Kram, a specialist in body movement at the University of Colorado in Boulder, US, says: “The biggest advantage will be for people who need to run with heavy loads, such as marines and fire fighters. It can be much more comfortable and less injurious. I would buy one.”

Will the Demise of the VHS Tape Curtail Creation of Culture?

BILL HAMMACK: Back in the 1980s, the Supreme Court ruled VCR makers couldn't be held liable for copyright infringement.

That gave consumers the right to make personal copies of TV shows and movies using a VCR.

The new digital media that are erasing the VHS format are also erasing our rights.

A few years ago, a Judge issued a catch-22 ruling: Yes, she said, we can copy commercial DVDs too. But no one can sell the software to do that.

In effect, that lets a content producer, the copyright owner, code their own intellectual property law into the DVD.

What's wrong with what? I mean surely only criminals would like to copy, right?

Well, wait a minute.

The U.S. has a long history of fair use: You have the right to cut out and frame a New Yorker cartoon. Or photocopy a newspaper article.

Fair use also catalyzes innovation and allows us to talk about ourselves, to create culture.

Take an artist of the future. He or she might want to make a statement using a bit of video or sound in a creative work.

But as all media — even books — become digital, every embodiment of thought or imagination becomes subject to commercial control.

DVDs use a technology called Digital Rights Management that allow producers to control when and where you watch.

They can specify whether you view a movie once or 100 times, and they can even restrict the devices you can play it on.

The slow demise of VHS tape risks the literary and intellectual canon of the coming century becoming locked into a digital vault accessible only to a few.

As our country moves forward to regulate digital copying, I urge us all to bear in mind T.S. Eliot's famous saying. "Good poets borrow; great poets steal."

A "Molecular Condom" against HIV

Vaginal gel liquefies to release an antiviral drug in response to semen

As part of a worldwide project to dramatically curtail the spread of AIDS, researchers have developed a vaginal gel designed to liquefy and release an antiviral drug when exposed to semen. Creators of the "molecular condom," still in very early testing, say the temperature- and pH-sensitive polymer could prove a more efficient way to deliver an anti-HIV drug than normal gels and creams.

"What we hope is that by attacking the virus in semen, we can inactivate it before it has any chance of permeating the tissue," says bioengineer Patrick Kiser of the University of Utah.

Kiser and his colleagues developed a polymer mixture that is liquid at room temperature, but thickens into a gellike coating at body temperature and a pH of 4 to 5, which occurs in the vagina. The researchers designed the gel to liquefy again at neutral PH, because semen neutralizes vaginal PH. Kiser says it can then mix with semen and deliver a desired antiviral payload, perhaps a small molecule or a polymer microbicide (microbe-killing compound).

The molecular condom is part of a global effort to come up with microbicides suspended in creams, gels or other materials to prevent the spread of the human immunodeficiency virus and other sexually transmitted diseases. Clinical trials are ongoing for at least a dozen different vaginal microbicides, according to the Alliance for Microbicide Development.

The trick, Kiser says, is to introduce such compounds as rapidly and as effectively as possible. "It could really only take minutes for the virus to come into contact with immune system cells," he explains, "so you don't really have a lot of time."

The molecular condom appears to be a relatively nontoxic way of quickly delivering an antiviral drug, according to a study by Kiser and his co-workers published online December 11 by the Journal of Pharmaceutical Sciences. The researchers report that it destroyed fewer mouse skin cells in the lab dish than two other products applied vaginally, including the routinely used spermicide nonoxynol-9.

The polymer also released 49 percent of a small dye molecule, which is chemically similar to some microbicides, within five minutes of exposure to a fluid that simulates semen, they found. Kiser warned, however, that researchers still must determine whether the gel causes any potentially dangerous side effects such as inflammation, which would attract immune cells that could serve as added targets for HIV infection.

The gel's staying power is yet to be determined, but Kiser says that based on its viscosity, it may remain in the vagina for up to a day. Retention time is key, he notes: "If a woman has to apply a microbicide right before sex, that's quite inconvenient."

"It's an exciting new way to think about things," says Polly Harrison, director of the Alliance for Microbicide Development. "We want to make these products as user-friendly as possible," and a gel that women could apply well in advance of sex "could be a real advantage."

Computers the Size of Sugar Cubes Could Record Entire Life in Two Decades

A device the size of a sugar cube will be able to record and store high resolution video footage of every second of a human life within two decades, experts said yesterday.

Researchers said governments and societies must urgently debate the implications of the huge increases in computing power and the growing mass of information being collected on individuals.

Some fear that the advent of "human black boxes" combined with the extension of medical, financial and other digital records will lead to loss of privacy and a dramatic expansion of the nanny state.

Others highlight positive advances in medicine, education, crime prevention and the way history will be recorded.

Leading computer scientists, psychologists and neuroscientists gathered to debate these issues at Memories for Life, a conference held at the British Library yesterday.

Prof Nigel Shadbolt, president of the British Computer Society and professor of artificial intelligence at the University of Southampton, said: "In 20 years' time it will be possible to record high quality digital video of an entire lifetime of human memories. It's not a question of whether it will happen; it's already happening."

Cliff Lynch, director of the US think tank Coalition for Networked Information, said the changes could lead to a dramatic extension of state interference.

"Imagine having a personal companion that whines at you three times a day, telling you that you are eating the wrong things and that you spent more than you earned today. The scary thing is it might be foisted on us."

Night Owls Are More Creative

Dec. 11, 2006 — Not a morning person? Take solace — new research suggests that "night owls" are more likely to be creative thinkers.

Scientists can't yet fully explain why evening types appear to be more creative, but they suggest it could be an adaptation to living outside of the norm.

"Being in a situation which diverges from conventional habit — nocturnal types often experience this situation — may encourage the development of a non-conventional spirit and of the ability to find alternative and original solutions," lead author Marina Giampietro and colleague G.M. Cavallera wrote in a study to be published in the February 2007 issue of Personality and Individual Differences.

The researchers, who are both in the Department of Psychology at the Catholic University of the Sacred Heart in Milan, Italy, studied 120 men and women of varying ages.

A self-report questionnaire evaluated degrees of morning and evening dispositions. In fact, true morning and evening-oriented people are actually rare, since most of us fall somewhere in between.

Once the subjects were categorized into either morning, evening or intermediate types, they underwent three tests designed to measure creative thinking.

During the first activity, test subjects were asked to draw and title a picture based on an image shown by the researchers. For the second activity, called "incomplete shapes," test subjects added lines to create pictures out of straight and curved lines. They then were asked to title the pictures.

The final test was similar, only this time the individuals were presented with 30 pairs of vertical lines.

Scientists scored each completed activity on originality, elaboration, fluidity and flexibility factors. Evening types aced each test based on these criteria, while morning and intermediate type people struggled to get scores over 50.

The researchers also discovered that age didn’t curtail creativity.

"Our study supports the notion that creative characteristics persist in aged people," the scientists wrote.

Hans Van Dongen, associate research professor at the Sleep and Performance Research Center at Washington State University, helped to discover the biological explanation behind morning and evening types.

He and his colleagues found that a small group of brain cells, called suprachiasmatic nuclei, emit signals to the body that synchronize the time of day. This "biological clock" runs two hours ahead in morning types and two hours later in evening types.

THE GREAT WEALTH TRANSFER

It's the biggest untold economic story of our time: more of the nation's bounty held in fewer and fewer hands. And Bush's tax cuts are only making the problem worse

PAUL KRUGMAN
Why doesn't Bush get credit for the strong economy?" That question has been asked over and over again in recent months by political pundits. After all, they point out, the gross domestic product is up; unemployment, at least according to official figures, is low by historical standards; and stocks have recovered much of the ground they lost in the early years of the decade, with the Dow surpassing 12,000 for the first time. Yet the public remains deeply unhappy with the state of the economy. In a recent poll, only a minority of Americans rated the economy as "excellent" or "good," while most consider it no better than "fair" or "poor."

Are people just ungrateful? Is the administration failing to get its message out? Are the news media, as conservatives darkly suggest, deliberately failing to report the good news?

None of the above. The reason most Americans think the economy is fair to poor is simple: For most Americans, it really is fair to poor. Wages have failed to keep up with rising prices. Even in 2005, a year in which the economy grew quite fast, the income of most non-elderly families lagged behind inflation. The number of Americans in poverty has risen even in the face of an official economic recovery, as has the number of Americans without health insurance. Most Americans are little, if any, better off than they were last year and definitely worse off than they were in 2000.

But how is this possible? The economic pie is getting bigger -- how can it be true that most Americans are getting smaller slices? The answer, of course, is that a few people are getting much, much bigger slices. Although wages have stagnated since Bush took office, corporate profits have doubled. The gap between the nation's CEOs and average workers is now ten times greater than it was a generation ago. And while Bush's tax cuts shaved only a few hundred dollars off the tax bills of most Americans, they saved the richest one percent more than $44,000 on average. In fact, once all of Bush's tax cuts take effect, it is estimated that those with incomes of more than $200,000 a year -- the richest five percent of the population -- will pocket almost half of the money. Those who make less than $75,000 a year -- eighty percent of America -- will receive barely a quarter of the cuts. In the Bush era, economic inequality is on the rise.

Rising inequality isn't new. The gap between rich and poor started growing before Ronald Reagan took office, and it continued to widen through the Clinton years. But what is happening under Bush is something entirely unprecedented: For the first time in our history, so much growth is being siphoned off to a small, wealthy minority that most Americans are failing to gain ground even during a time of economic growth -- and they know it.

America has never been an egalitarian society, but during the New Deal and the Second World War, government policies and organized labor combined to create a broad and solid middle class. The economic historians Claudia Goldin and Robert Margo call what happened between 1933 and 1945 the Great Compression: The rich got dramatically poorer while workers got considerably richer. Americans found themselves sharing broadly similar lifestyles in a way not seen since before the Civil War.

But in the 1970s, inequality began increasing again -- slowly at first, then more and more rapidly. You can see how much things have changed by comparing the state of affairs at America's largest employer, then and now. In 1969, General Motors was the country's largest corporation aside from AT&T, which enjoyed a government-guaranteed monopoly on phone service. GM paid its chief executive, James M. Roche, a salary of $795,000 -- the equivalent of $4.2 million today, adjusting for inflation. At the time, that was considered very high. But nobody denied that ordinary GM workers were paid pretty well. The average paycheck for production workers in the auto industry was almost $8,000 -- more than $45,000 today. GM workers, who also received excellent health and retirement benefits, were considered solidly in the middle class.

Today, Wal-Mart is America's largest corporation, with 1.3 million employees. H. Lee Scott, its chairman, is paid almost $23 million -- more than five times Roche's inflation-adjusted salary. Yet Scott's compensation excites relatively little comment, since it's not exceptional for the CEO of a large corporation these days. The wages paid to Wal-Mart's workers, on the other hand, do attract attention, because they are low even by current standards. On average, Wal-Mart's non-supervisory employees are paid $18,000 a year, far less than half what GM workers were paid thirty-five years ago, adjusted for inflation. And Wal-Mart is notorious both for how few of its workers receive health benefits and for the stinginess of those scarce benefits.

The broader picture is equally dismal. According to the federal Bureau of Labor Statistics, the hourly wage of the average American non-supervisory worker is actually lower, adjusted for inflation, than it was in 1970. Meanwhile, CEO pay has soared -- from less than thirty times the average wage to almost 300 times the typical worker's pay.

The widening gulf between workers and executives is part of a stunning increase in inequality throughout the U.S. economy during the past thirty years. To get a sense of just how dramatic that shift has been, imagine a line of 1,000 people who represent the entire population of America. They are standing in ascending order of income, with the poorest person on the left and the richest person on the right. And their height is proportional to their income -- the richer they are, the taller they are.

Start with 1973. If you assume that a height of six feet represents the average income in that year, the person on the far left side of the line -- representing those Americans living in extreme poverty -- is only sixteen inches tall. By the time you get to the guy at the extreme right, he towers over the line at more than 113 feet.

Now take 2005. The average height has grown from six feet to eight feet, reflecting the modest growth in average incomes over the past generation. And the poorest people on the left side of the line have grown at about the same rate as those near the middle -- the gap between the middle class and the poor, in other words, hasn't changed. But people to the right must have been taking some kind of extreme steroids: The guy at the end of the line is now 560 feet tall, almost five times taller than his 1973 counterpart.

What's useful about this image is that it explodes several comforting myths we like to tell ourselves about what is happening to our society.

MYTH #1: INEQUALITY IS MAINLY A PROBLEM OF POVERTY.
According to this view, most Americans are sharing in the economy's growth, with only a small minority at the bottom left behind. That places the onus for change on middle-class Americans who -- so the story goes -- will have to sacrifice some of their prosperity if they want to see poverty alleviated.

But as our line illustrates, that's just plain wrong. It's not only the poor who have fallen behind -- the normal-size people in the middle of the line haven't grown much, either. The real divergence in fortunes is between the great majority of Americans and a very small, extremely wealthy minority at the far right of the line.

MYTH #2: INEQUALITY IS MAINLY A PROBLEM OF EDUCATION.
This view -- which I think of as the eighty-twenty fallacy -- is expressed by none other than Alan Greenspan, former chairman of the Federal Reserve. Last year, Greenspan testified that wage gains were going primarily to skilled professionals with college educations -- "essentially," he said, "the top twenty percent." The other eighty percent -- those with less education -- are stuck in routine jobs being replaced by computers or lost to imports. Inequality, Greenspan concluded, is ultimately "an education problem."

It's a good story with a comforting conclusion: Education is the answer. But it's all wrong. A closer look at our line of Americans reveals why. The richest twenty percent are those standing between 800 and 1,000. But even those standing between 800 and 950 -- Americans who earn between $80,000 and $120,000 a year -- have done only slightly better than everyone to their left. Almost all of the gains over the past thirty years have gone to the fifty people at the very end of the line. Being highly educated won't make you into a winner in today's U.S. economy. At best, it makes you somewhat less of a loser.

MYTH #3: INEQUALITY DOESN'T REALLY MATTER.

In this view, America is the land of opportunity, where a poor young man or woman can vault into the upper class. In fact, while modest moves up and down the economic ladder are common, true Horatio Alger stories are very rare. America actually has less social mobility than other advanced countries: These days, Horatio Alger has moved to Canada or Finland. It's easier for a poor child to make it into the upper-middle class in just about every other advanced country -- including famously class-conscious Britain -- than it is in the United States.

Not only can few Americans hope to join the ranks of the rich, no matter how well educated or hardworking they may be -- their opportunities to do so are actually shrinking. As best we can tell, pretax incomes are now as unequally distributed as they were in the 1920s -- wiping out virtually all of the gains made by the middle class during the Great Compression.

There's a famous scene in the 1987 movie Wall Street in which Gordon Gekko, the corporate predator played by Michael Douglas, tells a meeting of stunned shareholders that greed is good, that the unbridled pursuit of individual wealth serves the interests of the company and the nation. In the movie, Gekko gets his comeuppance; in real life, the Gordon Gekkos took over both corporate America and, eventually, our political system.

Oliver Stone didn't conjure Gekko's "greed" line out of thin air. It was based on a real speech given by corporate raider Ivan Boesky -- and it reflected what many corporate executives, conservative intellectuals and right-wing politicians were saying at the time.

It's no coincidence that ringing endorsements of greed began to be heard at the same time that the actual incomes of America's rich began to soar. In part, the new pro-greed ideology was a way of rationalizing what was already happening. But it was also, to an important extent, a cause of the phenomenon. In the past thirty years, right-wing foundations have devoted enormous resources to promoting this agenda, building a far-reaching network of think tanks, media outlets and conservative scholars to legitimize higher levels of inequality. "On average, corporate America pays its most important leaders like bureaucrats," the Harvard Business Review lamented in 1990, calling for higher pay for top executives. "Is it any wonder then that so many CEOs act like bureaucrats?"

Although corporate executives have always had the power to pay themselves lavishly, their self-enrichment was limited by what Lucian Bebchuk, Jesse Fried and David Walker -- the leading experts on exploding executive paychecks -- call the "outrage constraint." What they mean is that a conspicuously self-dealing CEO would be forced to moderate his greed by unions, the press and politicians: The social climate itself condemned executive salaries that seem immodest.

Lately, however, we have experienced a death of outrage. Thanks to the right's well-funded and organized effort, corporate executives now feel no shame in lining their pockets with huge bonuses and gigantic stock options. Such self-dealing is justified, they say: Greed is what made America great, and greedy executives are exactly what corporate America needs.

At the same time, there has been a concerted attack on the institutions that have helped moderate inequality -- in particular, unions. During the Great Compression, the rate of unionization nearly tripled; by 1945, more than one in three American workers belonged to a union. A lot of what made General Motors the relatively egalitarian institution it was in the 1960s had to do with its powerful union, which was able to demand high wages for its members. Those wages, in turn, set a standard that elevated the income of workers who didn't belong to unions. But today, in the era of Wal-Mart, fewer than one in eleven workers in the private sector is organized -- effectively preventing hundreds of thousands of working Americans from joining the middle class.

Why isn't Wal-Mart unionized? The answer is simple and brutal: Business interests went on the offensive against unions. And we're not talking about gentle persuasion; we're talking about hardball tactics. During the late 1970s and early 1980s, at least one in every twenty workers who voted for a union was illegally fired; some estimates put the number as high as one in eight. And once Ronald Reagan took office, the anti-union campaign was aided and abetted by political support at the highest levels.

Unions weren't the only institution that fostered income equality during the generation that followed the Great Compression. The creation of a national minimum wage also set a benchmark for the entire economy, boosting the bargaining position of workers. But under Reagan, Congress failed to raise the minimum wage, allowing its value to be eroded by inflation. Between 1981 and 1989, the minimum wage remained the same in dollar terms -- but inflation shrank its purchasing power by twenty-five percent, reducing it to the lowest level since the 1950s.

After Reagan left office, there was a partial reversal of his anti-labor policies. The minimum wage was increased under the elder Bush and again under Clinton, restoring about half the ground it lost under Reagan. But then came Bush the Second -- and the balance of power shifted against workers and the middle class to a degree not seen since the Gilded Age.

During the 2000 election campaign, George W. Bush joked that his base consisted of the "haves and the have mores." But it wasn't much of a joke. Not only has the Bush administration favored the interests of the wealthiest few Americans over those of the middle class, it has consistently shown a preference for people who get their income from dividends and capital gains, rather than those who work for a living.

Under Bush, the economy has been growing at a reasonable pace for the past three years. But most Americans have failed to benefit from that growth. All indicators of the economic status of ordinary Americans -- poverty rates, family incomes, the number of people without health insurance -- show that most of us were worse off in 2005 than we were in 2000, and there's little reason to think that 2006 was much better.

So where did all the economic growth go? It went to a relative handful of people at the top. The earnings of the typical full-time worker, adjusted for inflation, have actually fallen since Bush took office. Pay for CEOs, meanwhile, has soared -- from 185 times that of average workers in 2003 to 279 times in 2005. And after-tax corporate profits have also skyrocketed, more than doubling since Bush took office. Those profits will eventually be reflected in dividends and capital gains, which accrue mainly to the very well-off: More than three-quarters of all stocks are owned by the richest ten percent of the population.

Bush wasn't directly responsible for the stagnation of wages and the surge in profits and executive compensation: The White House doesn't set wage rates or give CEOs stock options. But the government can tilt the balance of power between workers and bosses in many ways -- and at every juncture, this government has favored the bosses. There are four ways, in particular, that the Bush administration has helped make the poor poorer and the rich richer.

First, like Reagan, Bush has stood firmly against any increase in the minimum wage, even as inflation erodes the value of a dollar. The minimum wage was last raised in 1997; since then, inflation has cut the purchasing power of a minimum-wage worker's paycheck by twenty percent.

Second, again like Reagan, Bush has used the government's power to make it harder for workers to organize. The National Labor Relations Board, founded to protect the ability of workers to organize, has become for all practical purposes an agent of employers trying to prevent unionization. A spectacular example of this anti-union bias came just a few months ago. Under U.S. labor law, legal protections for union organizing do not extend to supervisors. But the Republican majority on the NLRB ruled that otherwise ordinary line workers who occasionally tell others what to do -- such as charge nurses, who primarily care for patients but also give instructions to other nurses on the same shift -- will now be considered supervisors. In a single administrative stroke, the Bush administration stripped as many as 8 million workers of their right to unionize.

Third, the administration effectively blocked what might have been a post-Enron backlash against self-dealing corporate insiders. Corporate scandals dominated the news in the first half of 2002 -- but then the subject was changed to the urgent need to invade Iraq, and the drive for reform was squelched. With Americans focused on the war, CEOs are once again rewarding themselves at impressive -- and unprecedented -- levels.

Finally, there's the government's most direct method of affecting incomes: taxes. In this arena, Bush has made sure that the rich pay lower taxes than they have in decades. According to the latest estimates, once the Bush tax cuts have taken full effect, more than a third of the cash will go to people making more than $500,000 a year -- a mere 0.8 percent of the population.

It's easy to get confused about the Bush tax cuts. For one thing, they are designed to confuse. The core of the Bush policy involves cutting taxes on high incomes, especially on the income wealthy Americans receive from capital gains and dividends. You might say that the Bush administration favors people who live off their wealth over people who have a job. But there are some middle-class "sweeteners" thrown in, so the administration can point to a few ordinary American families who have received significant tax cuts.

Furthermore, the administration has engaged in a systematic campaign of disinformation about whose taxes have been cut. Indeed, one of Bush's first actions after taking office was to tell the Treasury Department to stop producing estimates of how tax cuts are distributed by income class -- that is, information on who gained how much. Instead, official reports on taxes under Bush are textbook examples of how to mislead with statistics, presenting a welter of confusing numbers that convey the false impression that the tax cuts favor middle-class families, not the wealthy.

In reality, only a few middle-class families received a significant tax cut under Bush. But every wealthy American -- especially those who live off of stock earnings or their inheritance -- got a big tax cut. To picture who gained the most, imagine the son of a very wealthy man, who expects to inherit $50 million in stock and live off the dividends. Before the Bush tax cuts, our lucky heir-to-be would have paid about $27 million in estate taxes and contributed 39.6 percent of his dividend income in taxes. Once Bush's cuts go into effect, he could inherit the whole estate tax-free and pay a tax rate of only fifteen percent on his stock earnings. Truly, this is a very good time to be one of the have mores.

It's worth noting that Bush doesn't simply favor the upper class: It's the upper-upper class he cares about. That became clear last fall, when the House and Senate passed rival tax-cutting bills. (What were they doing cutting taxes yet again in the face of a huge budget deficit and an expensive war? Never mind.) The Senate bill was devoted to providing relief to middle-class wage earners: According to the Tax Policy Center, two-thirds of the Senate tax cut would have gone to people with incomes of between $100,000 and $500,000 a year. Those making more than $1 million a year would have received only eight percent of the cut.

The House bill, by contrast, focused on extending tax cuts on capital gains and dividends. More than forty percent of the House cuts would have flowed to the $1 million-plus group; only thirty percent to the 100K to 500K taxpayers.

The White House favored the House bill -- and the final, reconciled measure wound up awarding a quarter of the benefits to America's millionaires. That, in a nutshell, is the politics of income inequality under Bush.

Oh, one last thing: What about the claim that the Bush tax cuts did wonders for economic growth? In fact, job creation has been much slower under Bush than under Clinton, and overall growth since 2003 is largely the result of the huge housing boom, which has more to do with low interest rates than with taxes. But the biggest irony of all is that the real boom -- the one in the 1990s -- followed tax changes that were the reverse of Bush's policies. Clinton raised taxes on the rich, and the economy prospered.

A generation ago the distribution of income in the United States didn't look all that different from that of other advanced countries. We had more poverty, largely because of the unresolved legacy of slavery. But the gap between the economic elite and the middle class was no larger in America than it was in Europe.

Today, we're completely out of line with other advanced countries. The share of income received by the top 0.1 percent of Americans is twice the share received by the corresponding group in Britain, and three times the share in France. These days, to find societies as unequal as the United States you have to look beyond the advanced world, to Latin America. And if that comparison doesn't frighten you, it should.

The social and economic failure of Latin America is one of history's great tragedies. Our southern neighbors started out with natural and human resources at least as favorable for economic development as those in the United States. Yet over the course of the past two centuries, they fell steadily behind. Economic historians such as Kenneth Sokoloff of UCLA think they know why: Latin America got caught in an inequality trap. For historical reasons -- the kind of crops they grew, the elitist policies of colonial Spain -- Latin American societies started out with much more inequality than the societies of North America. But this inequality persisted, Sokoloff writes, because elites were able to "institutionalize an unequal distribution of political power" and to "use that greater influence to establish rules, laws and other government policies that advantaged members of the elite relative to non-members." Rather than making land available to small farmers, as the United States did with the Homestead Act, Latin American governments tended to give large blocks of public lands to people with the right connections. They also shortchanged basic education -- condemning millions to illiteracy. The result, Sokoloff notes, was "persistence over time of the high degree of inequality." This sharp inequality, in turn, doomed the economies of Latin America: Many talented people never got a chance to rise to their full potential, simply because they were born into the wrong class.

In addition, the statistical evidence shows, unequal societies tend to be corrupt societies. When there are huge disparities in wealth, the rich have both the motive and the means to corrupt the system on their behalf. In The New Industrial State, published in 1967, John Kenneth Galbraith dismissed any concern that corporate executives might exploit their position for personal gain, insisting that group decision-making would enforce "a high standard of personal honesty." But in recent years, the sheer amount of money paid to executives who are perceived as successful has overridden the restraints that Galbraith believed would control executive greed. Today, a top executive who pumps up his company's stock price by faking high profits can walk away with vast wealth even if the company later collapses, and the small chance he faces of going to jail isn't an effective deterrent. What's more, the group decision-making that Galbraith thought would prevent personal corruption doesn't work if everyone in the group can be bought off with a piece of the spoils -- which is more or less what happened at Enron. It is also what happens in Congress, when corporations share the spoils with our elected representatives in the form of generous campaign contributions and lucrative lobbying jobs.

As the past six years demonstrate, such political corruption only worsens as economic inequality rises. Indeed, the gap between rich and poor doesn't just mean that few Americans share in the benefits of economic growth -- it also undermines the sense of shared experience that binds us together as a nation. "Trust is based upon the belief that we are all in this together, part of a 'moral community,' " writes Eric Uslaner, a political scientist at the University of Maryland who has studied the effects of inequality on trust. "It is tough to convince people in a highly stratified society that the rich and the poor share common values, much less a common fate."

In the end, the effects of our growing economic inequality go far beyond dollars and cents. This, ultimately, is the most pressing question we face as a society today: Will the United States go down the path that Latin America followed -- one that leads to ever-growing disparity in political power as well as in income? The United States doesn't have Third World levels of economic inequality -- yet. But it is not hard to foresee, in the current state of our political and economic scene, the outline of a transformation into a permanently unequal society -- one that locks in and perpetuates the drastic economic polarization that is already dangerously far advanced.
