Rapid Mutation of RNA-Based Flu Virus Allows Rapid Adaptation to Immune System Response

I found the passage quoted below to be especially illuminating on how rapid mutation helps explain why the flu virus is so successful and dangerous. (An additional important factor is that the virus can survive in birds, without killing them.)
It occurs to me that something akin to rapid mutation (e.g., rapid experimentation) has also been advocated as a way to quickly advance science (Karl Popper), or enterprise (George Gilder).

(p. 105) Whenever an organism reproduces, its genes try to make exact copies of themselves. But sometimes mistakes–mutations–occur in this process.

This is true whether the genes belong to people, plants, or viruses. The more advanced the organism, however, the more mechanisms exist to prevent mutations. A person mutates at a much slower rate than bacteria, bacteria mutates at a much slower rate than a virus–and a DNA virus mutates at a much slower rate than an RNA virus.
DNA has a kind of built-in proofreading mechanism to cut down on copying mistakes. RNA has no proofreading mechanism whatsoever, no way to protect against mutation. So viruses that use RNA to carry their genetic information mutate much faster–from 10,000 to 1 million times faster–than any DNA virus.
Different RNA viruses mutate at different rates as well. A few mutate so rapidly that virologists consider them not so much a population of copies of the same virus as what they call a “quasi species” or a “mutant swarm.”
These mutant swarms contain trillions and trillions of closely related but different viruses. Even the viruses produced from a single cell will include many different versions of themselves, and the swarm as a whole will routinely contain almost every possible permutation of its genetic code.
Most of these mutations interfere with the functioning of the virus and will either destroy the virus outright or destroy its ability to infect. But other mutations, sometimes in a single base, a single letter, in its genetic code will allow the virus to adapt rapidly to a new situation. It is this adaptability that explains why these quasi species, these mutant swarms, can move rapidly back and forth between different environments and also develop extraordinarily rapid drug resistance. As one investigator has observed, the rapid mutation “confers a certain randomness to the disease processes that accompany RNA [viral] infections.”
Influenza is an RNA virus. So is HIV and the coronavirus. And of all RNA viruses, influenza and HIV are among those that mutate the fastest. The influenza virus mutates so fast that 99 percent of the 100,000 to 1 million new viruses that burst out of a cell in the reproduction process (p. 106) are too defective to infect another cell and reproduce again. But that still leaves between 1,000 and 10,000 viruses that can infect another cell.
Both influenza and HIV fit the concept of a quasi species, of a mutant swarm. In both, a drug-resistant mutation can emerge within days. And the influenza virus reproduces rapidly–far faster than HIV. Therefore it adapts rapidly as well, often too rapidly for the immune system to respond.

Measuring High Level Entrepreneurship

DiamondArtFrazerContestEntry2009.jpg

The Measurement Center of the Fraser Institute held a contest on the theme of what most needed to be better measured. I entered the contest, arguing that high level entrepreneurs are crucial to economic growth and human progress, and yet are not often the subject of systematic (as contrasted with anecdotal) study.
It turns out that my one minute video submission was picked as one of four “runners-up” in the contest.

George Shultz Sceptical of War on Drugs

George Shultz has a distinguished résumé. He was Dean of the University of Chicago business school, Secretary of the Treasury under President Nixon, and Secretary of State under President Reagan. Along with the late Milton Friedman, he is sceptical about the War on Drugs, and is willing to express his scepticism:

(p. A17) He has long harbored skepticism about interdiction as a solution to drug abuse in the U.S. Those doubts were prescient.
. . .
Mr. Shultz recalls what happened shortly after he left government, when his view that interdiction is not the solution came up after a speech to a Stanford alumni group.
Then, as now, he believed that we need to look at the problem from an economic perspective and understand what happens when there is high demand for a prohibited substance. When his comment hit the press, he says he “was inundated with letters. Ninety-eight percent of them agreed with me and over half of those people said I’m glad you said it, but I wouldn’t dare say it. The most poignant comment was from [a former member of the House of Representatives] who wrote and said I was glad to see your statement. I said that a few years ago and that’s why I’m no longer a congressman!”

Small Evidence Kills Big Theory

Raptorex_Trex2009-09-27.jpg

(p. A5) Paleontologists said Thursday that they had discovered what amounted to a miniature prototype of Tyrannosaurus rex, complete with the oversize head, powerful jaws, long legs — and, as every schoolchild knows, puny arms — that were hallmarks of the king of the dinosaurs.

But this scaled-down version, which was about nine feet long and weighed only 150 pounds, lived 125 million years ago, about 35 million years before giant Tyrannosaurs roamed the earth. So the discovery calls into question theories about the evolution of T. rex, which was about five times longer and almost 100 times heavier.
“The thought was these signature Tyrannosaur features evolved as a consequence of large body size,” Stephen L. Brusatte of the American Museum of National History, an author of a paper describing the dinosaur published online by the journal Science, said at a news conference. “They needed to modify their entire skeleton so they could function as a predator at such colossal size.”
The new dinosaur, named Raptorex kriegsteini, “really throws a wrench into this observed pattern,” Mr. Brusatte said.

Scientist Huxley: “The Great End of Life is Not Knowledge But Action”

John Barry calls our attention to the views of Thomas Huxley who gave the keynote address at the founding of the Johns Hopkins University:

(p. 13) A brilliant scientist, later president of the Royal Society, he advised investigators, “Sit down before a fact as a little child, be prepared to give up every preconceived notion. Follow humbly wherever and to whatever abysses nature leads, or you shall learn nothing.” He also believed that learning had purpose, stating, “The great end of life is not knowledge but action.”

“Recent Temperature Plateau” May Undermine Case for Global Warming

GlobalWarmingPlateauGraph2009-09-27.jpgSource of graph: online version of the NYT article quoted and cited below.

(p. A10) The world leaders who met at the United Nations to discuss climate change on Tuesday are faced with an intricate challenge: building momentum for an international climate treaty at a time when global temperatures have been relatively stable for a decade and may even drop in the next few years.

The plateau in temperatures has been seized upon by skeptics as evidence that the threat of global warming is overblown. And some climate experts worry that it could hamper treaty negotiations and slow the progress of legislation to curb carbon dioxide emissions in the United States.
. . .

Underscoring just how little clarity there is on short-term temperature fluctuations, researchers from Britain’s climate change office, in a paper published in August, projected “an end to this period of relative stability,” with half the years between now and 2015 exceeding the record-setting global temperatures of 1998.
Whatever the next decade may hold, critics of global warming have lost no time in using the current temperature plateau to build their case.
“I think it supports the arguments of those who’ve said, ‘What’s the rush for policy on this issue?’ ” said Patrick J. Michaels, a climatologist affiliated with George Mason University and the Cato Institute, a group opposing most regulatory solutions to environmental problems.
. . .

A clearer view of whether the recent temperature plateau undermines arguments for dangerous climate change in the long run should come in a few years, as the predictions made by the British climate researchers are tested. Their paper appeared in a supplement to an August issue of The Bulletin of the American Meteorological Society.
While the authors concluded that there was a 1 in 8 chance of having a decade-long pause in warming like the current plateau, even with rising concentrations of greenhouse gases, the odds of a 15-year pause, they wrote, are only 5 in 100. As a result, the next few years of observations could tip the balance toward further concern or greater optimism.
Meanwhile, social scientists who study the way people understand and respond to environmental problems say it is not surprising that the current temperature stability has created confusion and apathy.

Feds Spent $850,000 to “Green” Buildings, and then Tore Them Down

(p. 4A) WASHINGTON — The four drafty buildings had been fix­tures of the Energy Depart­ment complex in Oak Ridge, Tenn., for more than half a cen­tury. They burned energy like 1950s sedans.

The buildings seemed like perfect candidates for a federal conservation retrofit program that relies on private contrac­tors that receive a percentage of the money they save. A deal was struck in 2001. The con­tractor reworked lighting and heating systems, among other things, and began collecting payments.

The project was count­ed among the department’s “green” successes — until auditors discovered that the buildings had been torn down several years ago, and the gov­ernment had paid $850,000 for energy savings at facilities that no longer existed.

The audit findings show the potential for waste and abuse at a time when the department is poised to launch billions of dollars more in stimulus spend­ing on an unprecedented welter of green projects across the country.
. . .
The problems are not exclu­sive to Oak Ridge. The audi­tors, from the department’s inspector general’s office, also determined that $565,000 had been paid over six years un­der the same arrangement to a contractor in Texas for a high­efficiency laundry that was no longer in use.

The department also paid out $3.4 million on another project without checking whether the conservation measures worked — and $160,000 for measure­ments that were never taken.

Happy Entrepreneur: “Even When Things Get Tough, I’m Still in Control”

PeugeotRogerHappyPlumber2009-09-27.jpg “‘Roger the Plumber’ owns his own business and is excited to go to work every day.” Source of caption and photo: online version of the WSJ article quoted and cited below.

(p. D1) By economic yardsticks, Roger the Plumber should be feeling pretty low. Roger Peugeot, owner of the 14-employee Overland Park, Kan., plumbing company that bears his name, is part of a sector hit hard by shrunken credit and slumping sales. He has been forced to reduce staff and is battling new competition from other plumbers fleeing the construction industry.

So why is Mr. Peugeot so happy? He genuinely likes fixing plumbing messes, for one thing, and despite the worst recession he has seen, “I’m still excited to get up and go to work every day,” he says. He relishes running into people at the local hardware store whom he has helped in the past. And in hard times, he says, his fate is in his own hands, rather than those of a manager. “Even when things get tough, I’m still in control,” he says.
In the broadest, most-comprehensive survey yet of how occupation affects happiness, business owners outrank 10 other occupational groups in overall well-being, based on the landmark survey of 100,826 working adults set for release today. Defined as self-employed store or factory owners, plumbers and so on, business owners surpassed 10 other occupational groups on a composite measure of six criteria of contentment, including emotional and physical health, job satisfaction, healthy behavior, access to basic needs and self-reports of overall life quality.
This puts Roger the Plumber well ahead of movers and shakers typically regarded as the top of the heap in society–professionals such as doctors or lawyers, who ranked second, and executives and managers in corporations or government, who came in third–according to the Gallup-Healthways Well-Being Index, a collaboration between Gallup and Healthways, a Franklin, Tenn., health-management concern. This is despite business owners ranking below those more-prestigious occupations in physical health and access to basic needs, such as health care.
. . .
“Despite the recession, it still pays to be your own boss,” says Frank Newport, editor in chief of the Gallup Poll. The survey, adds John Howard, director of the National Institute for Occupational Safety and Health, “reaffirms my view that the more control you have over your work, the happier you are.”

How Wilson and the Feds Turned “Only Influenza” into “The Great Influenza”

Here is the core of John Barry’s account of how President Woodrow Wilson, and his administration, turned what might have been an ordinary flu, into what, by some measures, was the worst pandemic in human history:

(p. 396) . . . , whoever held power, whether a city government or some private gathering of the locals, they generally failed to keep the community together. They failed because they lost trust. They lost trust because they lied. (San Francisco was a rare exception; its leaders told the truth, and the city responded heroically.) And they lied for the war effort, for the propaganda machine that Wilson had created.

It is impossible to quantify how many deaths the lies caused. It is impossible to quantify how many young men died because the army refused to follow the advice of its own surgeon general. But while those in authority were reassuring people that this was influenza, only influenza, nothing different from ordinary “la grippe,’ at least some people must have believed them, at least some people must have exposed themselves to the virus in ways they would not have otherwise, and at least some of these people must have died who would otherwise have lived. And fear really did kill people. It killed them because those who feared would not care for many of those who needed but could not find care, those who needed only hydration, food, and rest to survive.

How Government Universal Health Care Works in India

JahanAmirIndianWeaver2009-09-26.jpg “Amir Jahan found her health insurance wouldn’t pay for all of her $200 stomach surgery; she continues to work with an untreated tumor.” Source of caption: print version of the WSJ article quoted and cited below. Source of photo: online version of the WSJ article quoted and cited below.

(p. A14) PANIPAT, India — Amir Jahan can spin thick, white thread into magnificent cloth, but the 46-year-old weaver has been unable to unravel her health plan to pay for stomach surgery.

Under a health-insurance program introduced a few years ago, the Indian government has provided health-insurance coverage for the country’s hand-loom weavers, a group of 6.5 million workers, 60% of them female, who are mostly illiterate and invariably poor. Yet holding an insurance card hasn’t helped Ms. Jahan, who says the coverage only pays for minor ailments and not for major problems, such as the removal of a stomach tumor.
“The health care is all a sham,” Ms. Jahan says angrily. “I was refused treatment on grounds of huge expense. I won’t ever go to be humiliated again.”
Ms. Jahan’s health-care issues represent the problems that come with trying to provide insurance to India’s poor. Access to quality care remains a distant dream for many in this country of 1.1 billion.
Last year, the Indian government launched the National Health Insurance Program on (sic) promised health coverage of $700 per person for families earning less than $100 a year.
Holders of health cards have to register in their home states to access benefits, thereby precluding a large population of migrant laborers. Those who can get past the complex state-identification and qualification process often can’t cope with hospital bureaucracies.

Gallup Finds Highest Doubts of Government in Decades

(p. A23) If you want to know why Americans are so fearful of a government takeover of the health-care system, take a look at the results of a new Gallup poll on government waste released Sept. 15. One question posed was: “Of every tax dollar that goes to Washington, D.C., how many cents of each dollar would you say is wasted?” Gallup found that the mean response was 50 cents. With Uncle Sam spending just shy of $4 trillion this year, that means the public believes that $2 trillion is wasted.

In a separate poll released on Monday, Gallup found that nearly twice as many Americans believe that there is “too much government regulation of business and industry” as believe there is “too little” (45% to 24%).
Perhaps most significantly, in both of these polls Gallup found that skepticism about government’s effectiveness is the highest it’s been in decades. “Perceptions of federal waste were significantly lower 30 years ago than today,” say the Gallup researchers. Even when Ronald Reagan was elected president in 1980 with the help of the antigovernment revolt of that era, Americans believed only 40 cents of every dollar was wasted, according to Gallup.
. . .
Over the last decade, the federal government has become bloated and inefficient. Voters are on to the scam. Mr. Obama keeps calling federal spending an “investment,” but Americans apparently feel this is the worst investment they’ve ever made. They’ve come to regard Washington as a $2 trillion Bridge to Nowhere. They are right.
