mm385: Scientific victories are often ephemeral

MUDGE’s Musings

Here in the replete West, such as at the home of yr (justifiably) humble svt, rice is an occasional side dish, a refreshing change from a potato, or pasta, usually accompanying a steaming chunk of animal protein.

In the hungry not-West, rice is entirely it.

Rice has been distressingly newsworthy lately, as prices have been climbing.

Even before this month’s very bad news (the story below, as well as the Burma cyclone of a couple of weeks ago that hit Southeast Asia’s rice bowl (Burma’s Irrawaddy delta) the hardest), there were shortages and unrest, sometimes violent, due to skyrocketing rice prices.

But the NYTimes makes clear, the latest threat to rice, and thus to the staple food of billions, is the lack of momentum in agricultural research.

Today’s villain is called the brown plant hopper. And it could have been stopped in its tracks, had the research establishment kept its eye on the ball.

The Food Chain

World’s Poor Pay Price as Crop Research Is Cut

By KEITH BRADSHER and ANDREW MARTIN | Published: May 18, 2008

LOS BAÑOS, Philippines — The brown plant hopper, an insect no bigger than a gnat, is multiplying by the billions and chewing through rice paddies in East Asia, threatening the diets of many poor people.

Researchers at the International Rice Research Institute in the Philippines, the world’s main repository of information about rice, are trying to deal with problems like the rice hopper, which destroys plants, by developing stronger varieties of rice.

The damage to rice crops, occurring at a time of scarcity and high prices, could have been prevented. Researchers at the International Rice Research Institute here say that they know how to create rice varieties resistant to the insects but that budget cuts have prevented them from doing so.

Culling the planet’s herd

A couple of days ago, we explored some of the implications of the FDA’s approval to introduce cloned meat and dairy products into the marketplace. The concern is that as producers go for the easy, repetitive score, i.e., clone what works and eliminate the rest, the planet will permanently lose something important: species diversity.

This week’s NYTimes Magazine explores the issue from a different direction (and continent!), selective breeding rather than cloning (two sides of the same coin, actually).

A Dying Breed

By ANDREW RICE | Published: January 27, 2008

GERSHOM MUGIRA COMES from a long line of cattle-keepers. His people, the Bahima, are thought to have migrated into the hilly grasslands of western Uganda more than a thousand years ago, alongside a hardy breed of longhorns known as the Ankole. For centuries, man and beast subsisted there in a tight symbiotic embrace. Mugira’s nomadic ancestors wandered in search of fresh pasture for their cattle, which in turn provided them with milk. It is only within the last few generations that most Bahima have accepted the concept of private property. Mugira’s family lives on a 500-acre ranch, and one sunny day in November, the wiry 26-year-old showed me around, explaining, with some sadness but more pragmatism, why the Ankole breed that sustained his forebears for so many generations is now being driven to extinction….

In recent decades, global trade, sophisticated marketing, artificial insemination and the demands of agricultural economics have transformed the Holstein into the world’s predominant dairy breed. Indigenous animals like East Africa’s sinewy Ankole, the product of centuries of selection for traits adapted to harsh conditions, are struggling to compete with foreign imports bred for maximal production. This worries some scientists. The world’s food supply is increasingly dependent on a small and narrowing list of highly engineered breeds: the Holstein, the Large White pig and the Rhode Island Red and Leghorn chickens. There’s a risk that future diseases could ravage these homogeneous animal populations. Poor countries, which possess much of the world’s vanishing biodiversity, may also be discarding breeds that possess undiscovered genetic advantages. But farmers like Mugira say they can’t afford to wait for science. And so, on the African savanna, a competition for survival is underway….

The Food and Agriculture Organization, an agency of the United Nations, recently reported that at least 20 percent of the world’s estimated 7,600 livestock breeds are in danger of extinction. Experts are warning of a potential “meltdown” in global genetic diversity. Yet the plight of the Ankole illustrates the difficulty of balancing the conflicting goals of animal conservation and human prosperity. An estimated 70 percent of the world’s rural poor, some 630 million people, derive a substantial percentage of their income from livestock. Increase the productivity of these animals, development specialists say, and you improve dire living standards. The World Bank recently published a report saying it was time to place farming “afresh at the center of the development agenda.” Highly productive livestock breeds, the World Bank asserts, are playing an important role in alleviating poverty.

As controlled interbreeding takes place, Africa’s indigenous cattle are gradually converting into distinctly highly productive Holsteins.

One additional advantage of the imported genetic stock: Ankole cattle require huge swaths of grassland; Holsteins can be penned. Writer Andrew Rice quotes some experts who say that “ethnic” warfare in Rwanda and Darfur as “really a fight over grass.”

The diversity the planet is losing is dire:

Many tropical breeds may possess unique adaptive traits. The problem is, we don’t know what is being lost. Earlier this year, the U.N.’s Food and Agriculture Organization released its first-ever global assessment of biodiversity in livestock. While data on many breeds are scant, the report found that over the last six years, an average of one breed a month has gone extinct. “The threat is imminent,” says Danielle Nierenberg, senior researcher at the Worldwatch Institute, an environmental group. “Just getting milk and meat into people’s mouths is not the answer.”

Shanghai’s Middle Class Launches Quiet, Meticulous Revolt

By Maureen Fan | Washington Post Foreign Service | Saturday, January 26, 2008

SHANGHAI — Bundled against the cold, the businessman made his way down the steps. Coming toward him in blue mittens was a middle-aged woman.

“Do you know that we’re going to take a stroll this weekend?” she whispered, using the latest euphemism for the unofficial protests that have unnerved authorities in Shanghai over the past month.

He nodded.

Behind her, protest banners streamed from the windows of high-rise apartment blocks, signs of middle-class discontent over a planned extension of the city’s magnetic levitation, or maglev, train through residential neighborhoods.

They live in China’s most Western mainland city, and they’ve learned the advanced Western concept of NIMBY (Not in my back yard). And they’ve taken to the streets.

And Shanghai’s government has been forced to pay attention.

Shanghai’s Middle Class Launches Quiet, Meticulous Revolt – washingtonpost.com

The single most relentless enemy of authoritarian governments is the middle class. Even George III’s Venezuelan nemesis, Hugo Chavez, failed in his attempt to modify the constitution.

Citizens who have attained middle class status by dint of hard work, and loosened societal constraints, can embrace artifacts of civilization available to those living above the subsistence level.

Such as education.

Satellite television (Ronald Reagan and CNN both helped end the Cold War, to MUDGE’s generation’s eternal surprise).

The Internet and its blogs and bulletin boards (those portions that the Chinese government can’t censor).

Cellular telephones with text messaging.

Don’t think there’s much of a middle class in Burma as yet. So that 2007 effort was doomed. Like Chicago Cubs fans everywhere, one can only say, “wait until next year!”

Closing the Barn Door After the Cows Have Gotten Out

By VERLYN KLINKENBORG | Published: January 23, 2008

Last week, the Food and Drug Administration cleared the way for the eventual sale of meat and dairy products from cloned animals, saying, in effect, that consumers face no health risks from them. The next day, the Department of Agriculture asked farmers to keep their cloned animals off the market until consumers have time to get over their anticloning prejudice. That is one prejudice I plan to hold on to. I will not be eating cloned meat.

The reason has nothing to do with my personal health or safety. I think the clearest way to understand the problem with cloning is to consider a broader question: Who benefits from it? Proponents will say that the consumer does, because we will get higher quality, more consistent foods from cloned animals. But the real beneficiaries are the nation’s large meatpacking companies — the kind that would like it best if chickens grew in the shape of nuggets. Anyone who really cares about food — its different tastes, textures and delights — is more interested in diversity than uniformity.

A felicitous turn of phrase: … “meatpacking companies – the kind that would like it best if chickens grew in the shape of nuggets.” Wow! Wish I could write like that!

Species diversity is a good thing, and cloning is its enemy.

mm236: If Bt corn is controversial, genetically modified wine is sure to be cataclysmic

December 29, 2007

MUDGE’S Musings

“Wine is constant proof that God loves us and loves to see us happy.” — Benjamin Franklin

Europe’s concerns with genetically modified corn hit the news, and this nanocorner of the ‘Sphere©, earlier this week.

The best magazine on the planet, The Economist weighs in with a GM story that, in the same way a short piece in the same year-end issue highlighted a troubled future for beer, explores science’s impingement on that nectar of the gods, wine.

A research team in Italy has just published the complete genetic sequence for the pinot noir grape.

So what, one might ask…

Dr Velasco’s efforts have discovered a treasure trove of information for technologically oriented winemakers. His group has found hundreds of genes that encode enzymes which produce flavourings and aromatic compounds. That will help both those who want to make flavours more consistent and those who want to add novelty.

Further, those seeking genetic solutions for bacterial and viral infections that have limited the ability to grow wine grapes in certain locations, now have the genetic ammunition required to design precise solutions.

Grape genetics | Vine times

Dec 19th 2007 | From The Economist print edition

The pinot noir genome is sequenced. GM wine, anyone?

THE battle between those who think character comes from nature and those who think nurture is the key is not confined to students of humanity. It lies at the heart of winemaking, too. For European growers, the variety of grape is important, of course. No one would mistake cabernet sauvignon for sangiovese or riesling for chardonnay. But grape varieties are normally propagated as cuttings; in other words, clones. What creates a wine’s character, they argue, is the terroir—that mysterious combination of soil and microclimate that gives appellations contrôlées their cachet. In other words, the essence of a wine lies in its nurture.

In an opinion piece in the same issue, the editors of Economist are quite amusing while exploring the implications of highly precise genetic manipulation on wine.

Unleash the war on terroir

Dec 19th 2007 | From The Economist print edition

An oenological wish-list for the drinking season

… Why should sauvignon blanc be stuck with boring old gooseberry and cabernet sauvignon with cassis? Genomics could beget some novel wine flavours and combinations to ensure the wine really does go with the food: pinot noir with cranberries, pork, and sage and onion stuffing, perhaps….

A gene for producing acetylsalicylic acid, better known as aspirin, would help to prevent heart attacks and blood clots. You could get your doctor to supply your daily half-bottle by prescription. The aspirin’s analgesic effect would head off hangovers before they even started. Caffeine could be added to keep drinkers awake during boring dinner parties. And it may even be possible to insert a gene to produce sildenafil citrate, the active ingredient in Viagra. For many men that would help to prevent the ultimate wine-induced humiliation.

The beer crisis | Trouble brewing

Dec 19th 2007 | ST LOUIS | From The Economist print edition

A shortage of hops threatens Christmas

JUST as the festive season gets going, drinkers in America are finding their favourite beer suddenly more expensive or even—horrors!—not available at all. Hit by price increases and shortages, many breweries, particularly the small “craft brewers” and the even smaller microbreweries, are being forced to raise prices, make do with modified recipes or shut off the spigots altogether.

The humble hop, the plant that gives beer its distinctive flavour, is the main problem. Many farmers in the Pacific north-west, where America’s hop production is concentrated, have turned to more profitable lines—especially corn, which can be made into ethanol. The decrease in hop production, put at some 50% over the past decade, has sent prices through the roof. Brian Owens, the brewmaster of the O’Fallon Brewery near St Louis, Missouri, says that the variety he once bought for $3 a pound (0.45kg) now costs five times that. Many smaller breweries cannot find what they need at any price. Industry giants like Anheuser-Busch and Miller are better off, thanks to long-term contracts. But even Anheuser-Busch has been forced to raise prices for its six-packs.

A crisis of tragically epic proportions: beer unavailable, especially the increasingly popular craft or microbrews, or priced higher due to the newly high price of hops and barley.

Yr (justifiably) humble svt is somewhat cavalier about beer, as he doesn’t drink it very often (the carbs, don’t you know), but in tough times (and they seem to be inching toward tough in these parts) one takes solace where one can, and beer is the solace of choice for many. A shortage, or a significantly higher price, could wreak havoc with the social order.

And, what’s the cause of this potential unrest? Corn.

Corn is supplanting hops and barley for many farmers, since the government has made it increasingly attractive to grow corn for ethanol, totally wrongheaded though that is wrongheaded government! Go figure!

See some previous posts on the use of ethanol as fuel: starting here in the earliest days of this nanocorner of the ‘Sphere©, and here, here, here, here.

[Please click the link below for the complete article — but then please come on back!]

The beer crisis | Trouble brewing | Economist.com

Ethanol, inefficient as it is as fuel, causing shortages and price increases of one of the major food groups (for many): beer. Talk about the law of unintended consequences…

Thus corn was on my mind when we encountered this article in the NYTimes today. The European Union is once again (still?) grappling with the high intensity issue of the advisability of growing genetically modified corn.

GM foods is a topic we’ve handled quite eloquently (MUDGE’s humility gene must have gotten in the way of an X-ray machine, sorry) in a previous post. But, news is news.

And the Times is quite thorough covering both points of view. Interestingly, there’s actual science supporting both, as opposed to the recent cases where science is called into question on this side of the water and those callers into question can hardly spell the word science (guess the word doesn’t appear in the King James edition) much less accept its findings.

Both Sides Cite Science to Address Altered Corn

By ELISABETH ROSENTHAL | Published: December 26, 2007

BRUSSELS — A proposal that Europe’s top environment official made last month, to ban the planting of a genetically modified corn strain, sets up a bitter war within the European Union, where politicians have done their best to dance around the issue.

The environmental commissioner, Stavros Dimas, said he had based his decision squarely on scientific studies suggesting that long-term uncertainties and risks remain in planting the so-called Bt corn. But when the full European Commission takes up the matter in the next couple of months, commissioners will have to decide what mix of science, politics and trade to apply. And they will face the ambiguous limits of science when it is applied to public policy.

Europe has embargoed seed and food products grown from genetically engineered plants for a decade; very convenient excuse for protectionist trade barriers. Now the World Trade Organization is pushing the EU for a change in policy. But the EU is pushing back, citing scientific studies counter to those presented in favor of GM food:

Ms. Hilbeck says that company-financed studies do not devote adequate attention to broad ripple effects that modified plants might cause, like changes to bird species or the effect of all farmers planting a single biotechnology crop. She said producers of modified organisms, like Syngenta and Monsanto, have rejected repeated requests to release seeds to researchers like herself to conduct independent studies on their effect on the environment.

The give and take on this is interesting.

[Please click the link below for the complete article — but then please come on back!]

Both Sides Cite Science to Address Altered Corn – New York Times

So it’s your scientists vs. my scientists, and because it’s science, there’s room for opposing theories. But the EU’s science has that slightly moldy odor of politics.

As mentioned in the post cited at the top, because of our employment at the time we were close to this debate 10 years ago in the U.S. That battle was hard fought, biotechnology vs. the Monarch butterfly (talk about a public relations nightmare for the suits!), and ultimately won in the U.S. by Big Ag, although as the Times makes clear, the Monarch’s well-being is still closely studied.

In the United States, where almost all crops are now genetically modified, the debate is largely closed.

“I’m not saying there are no more questions to pursue, but whether it’s good or bad to plant Bt corn — I think we’re beyond that,” said Richard L. Hellmich, a plant scientist with the Agriculture Department who is based at Iowa State University. He noted that hundreds of studies had been done and that Bt corn could help “feed the world.”

But the scientific equation may look different in Europe, with its increasing green consciousness and strong agricultural traditions.

And, if you let your farmers start to grow GM foods, it will be more difficult to rationalize the artificial protectionist barriers against other modified crops.

The hungry of the world (and there are so many!) can’t eat paper; unfortunately paper seems to be the chief crop of most of the world’s governments.

It’s it for now. Thanks,

mm201: Stemming the tide of ignorance despite the neocons

November 22, 2007

MUDGE’S Musings

Last post, we picked up on the report that stem cell researchers have an alternative source for the miracle tools. The writer of that NYTimes story follows up with a sidebar on the lead scientist, James A. Thomson of the University of Wisconsin, who has played a leading, even defining, role in stem cell research for more than a decade.

nytimes3_thumb1

By GINA KOLATA

If the stem cell wars are indeed nearly over, no one will savor the peace more than James A. Thomson.

Dr. Thomson’s laboratory at the University of Wisconsin was one of two that in 1998 plucked stem cells from human embryos for the first time, destroying the embryos in the process and touching off a divisive national debate.

And on Tuesday, his laboratory was one of two that reported a new way to turn ordinary human skin cells into what appear to be embryonic stem cells without ever using a human embryo.

Turns out that Dr. Thomson was, as he and his UW colleagues report it, concerned about the ethical implications of stem cell research from the beginning.

Man Who Helped Start Stem Cell War May End It – New York Times

Some of the commentary others in the blogosphere have shared since the original story hit the other day have expressed a good deal of knee-jerk cynicism regarding the nature of this latest twist. It’s just so perfect that this latest news fits so well with Bush administration dogma. See, you can do your research without abortion!

People, this isn’t politics, or religion; it’s science. Forced by ethical, political and/or religious imperatives to curtail stem cell research, many wrung their hands, took off to more scientifically adventurous locales, or found a new field to pursue.

Thomson, and, separately, Shinya Yamanaka of Kyoto University, decided that the potential for breakthrough discoveries was too important, and figuratively lit a candle rather than curse the darkness, and began the work that resulted in this weeks breakthrough announcements.

MUDGE chooses to suspend cynicism (after all, it’s a holiday in the U.S. today!), and believe the best. Okay, so this fits with distorted agenda of the neo-con know-nothings who have distorted too much and spread a huge swath of medieval ignorance over too much of our culture.

But, sometimes, even good news for the dolts is good news for humankind, and this discovery, whose potential to accelerate further discoveries into the cause, prevention and cure of many neurological diseases that have caused such misery in the world, is worthy of our Thanksgiving celebration.

mm200: Stem cells: Unlike oil, we now have an alternative source

November 21, 2007

MUDGE’S Musings

Stem cell research, emblematic of all that’s promising regarding the ability of scientists to remedy hitherto incurable diseases. Stem cell research, emblematic of the George III administration’s wrong-headedness in nearly every important issue of our times.

Until yesterday, stem cell researchers found their most promising source material in human embryos, whose availability is, one presumes, mainly dependent upon the supply resulting from aborting pregnancies.

Since 1973, such supplies have been legally available to science in the U.S. Since the Bush administration outlawed the practice (or severely curtailed the use of new embryonic material by restricting federal funds required to finance it), researchers into cures for the crippling and fatal diseases that include multiple sclerosis, ALS (amyotrophic lateral sclerosis, Lou Gehrig’s disease), Parkinson’s and Alzheimer’s have been thwarted from fully pursuing this most promising field of research.

Now it appears that scientists have discovered an alternative to embryos as the feedstock for stem cells.

nytimes3

By GINA KOLATA

Published: November 21, 2007

Two teams of scientists reported yesterday that they had turned human skin cells into what appear to be embryonic stem cells without having to make or destroy an embryo — a feat that could quell the ethical debate troubling the field.

All they had to do, the scientists said, was add four genes. The genes reprogrammed the chromosomes of the skin cells, making the cells into blank slates that should be able to turn into any of the 220 cell types of the human body, be it heart, brain, blood or bone. Until now, the only way to get such human universal cells was to pluck them from a human embryo several days after fertilization, destroying the embryo in the process.

Science in the pursuit of prevention or remediating disease is critical, and the fact that it has been hamstrung over this moral quandary, mainly promoted by those same folks who brought you Creationism, is yet another embarrassing lowlight of the past seven years.

So much of what research has been occurring moved offshore (as so many other occupations have). But, science is always attempting to navigate new ways around knowledge gaps, and this promising achievement is an eye-opening demonstration.

Scientists Bypass Need for Embryo to Get Stem Cells – New York Times

So there’s much work left to do before this new process is proven successful — the fact that a cancer gene is part of the process sounds distressing — but we can’t help but be hopeful that, after years of roadblocks, necessary research into the causes, prevention and cures of some of the most dreadful diseases can resume at full throttle.

In the long run, the new process might prove to be more useful, with wider application than the controversial one. So in a way, maybe the know-nothings did science a favor.

Irony. Today’s sixth sense.

The real GM food scandal

by Dick Taverne

GM foods are safe, healthy and essential if we ever want to achieve decent living standards for the world’s growing population. Misplaced moralising about them in the west is costing millions of lives in poor countries

Dick Taverne is the author of The March of Unreason: Science, Democracy and the New Fundamentalism (OUP)

Seven years ago, Time magazine featured the Swiss biologist Ingo Potrykus on its cover. As the principal creator of genetically modified rice—or “golden rice”—he was hailed as potentially one of mankind’s great benefactors. Golden rice was to be the start of a new green revolution to improve the lives of millions of the poorest people in the world. It would help remedy vitamin A deficiency, the cause of 1-2m deaths a year, and could save up to 500,000 children a year from going blind. It was the flagship of plant biotechnology. No other scientific development in agriculture in recent times held out greater promise.

Seven years later, the most optimistic forecast is that it will take another five or six years before golden rice is grown commercially. The realisation of Potrykus’s dream keeps receding. The promised benefits from other GM crops that should reduce hunger and disease have been equally elusive. GM crops should now be growing in areas where no crops can grow: drought-resistant crops in arid soil and salt-resistant crops in soil of high salinity. Plant-based oral vaccines should now be saving millions of deaths from diarrhoea and hepatitis B; they can be ingested in orange juice, bananas or tomatoes, avoiding the need for injection and for trained staff to administer them and refrigeration to store them.

Your correspondent has long been more aware of this complex issue than the average blogger on the street. Some years ago, MUDGE logged a five-year stint at a science-based organization whose parent was one of the foremost corporate proponents of this world-changing technology. Indeed, I probably would be there still, had not the forces of creative destruction, i.e., capitalism, broken up that good old gang of mine through “merger” and acquisition.

Proximity to the technology, and a modicum of intellectual curiosity resulted in slightly more than superficial awareness of the issue and its controversies. And the controversy has been noisy enough to make one believe that distribution of such technology has been suppressed. But,

Seldom has public perception been more out of line with the facts. The public in Britain and Europe seems unaware of the astonishing success of GM crops in the rest of the world. No new agricultural technology in recent times has spread faster and more widely. Only a decade after their commercial introduction, GM crops are now cultivated in 22 countries on over 100m hectares (an area more than four times the size of Britain) by over 10m farmers, of whom 9m are resource-poor farmers in developing countries, mainly India and China. Most of these small-scale farmers grow pest-resistant GM cotton. In India alone, production tripled last year to over 3.6m hectares. This cotton benefits farmers because it reduces the need for insecticides, thereby increasing their income and also improving their health. It is true that the promised development of staple GM food crops for the developing world has been delayed, but this is not because of technical flaws. It is principally because GM crops, unlike conventional crops, must overcome costly, time-consuming and unnecessary regulatory obstacles before they can be licensed.

And the demonizing of GM technology has no foundation in science.

The fact is that there is not a shred of any evidence of risk to human health from GM crops. Every academy of science, representing the views of the world’s leading experts—the Indian, Chinese, Mexican, Brazilian, French and American academies as well as the Royal Society, which has published four separate reports on the issue—has confirmed this. Independent inquiries have found that the risk from GM crops is no greater than that from conventionally grown crops that do not have to undergo such testing. In 2001, the research directorate of the EU commission released a summary of 81 scientific studies financed by the EU itself—not by private industry—conducted over a 15-year period, to determine whether GM products were unsafe or insufficiently tested: none found evidence of harm to humans or to the environment.

In the analysis considered here, the thesis is proposed that the large agribusinesses planted the seeds, as it were, of their own difficulties promoting this technology due to their own public-relations (rather than science) based caution.

And MUDGE remembers distinctly the emotional and distracting case of the supposed endangerment of monarch butterflies due to GM corn.

And what has always grabbed this non-scientist observer is that, throughout the history of agriculture (which encompasses the development of modern humankind) farmers have cross-bred and otherwise genetically modified their crops. What modern technology offers the process is predictability and repeatability.

So, as we hope you’ve taken the trouble to read to the end, the author expresses some hope that people are finally coming to their senses regarding the issue of GM crops.

There can be little doubt that GM crops will be accepted worldwide in time, even in Europe. But in delaying cultivation, the anti-GM lobbies have exacted a heavy price. Their opposition has undermined agrobusiness in Europe and has driven abroad much research into plant biotechnology—an area in which Britain formerly excelled. Over-regulation may well cause the costs of the technology to remain higher than they need be. Above all, delay has caused the needless loss of millions of lives in the developing world. These lobbies and their friends in the organic movement have much to answer for.

So, once again, seemingly well-informed people are proven to be misinformed. Hardly shocking anymore, but very, very disturbing.

Africans and others in the developing world are starving, people! GM crops can be engineered to use less pesticide, less fertilizer, less water (the last great resource battleground), to get more, and better, food into the empty stomachs of the world.

Wake up and pay attention, you enemies of science!

It’s it for now. Thanks,

Kicking Butt – The international jihad against tobacco.

I hate smoking. It’s a filthy habit. It kills hundreds of millions of people, including bystanders. Just being around it makes me nauseous. Cities, states, and countries all over the world are banning smoking in public, and I couldn’t be happier.

In fact, it’s such a rout, it’s getting out of hand.

The problem with tobacco all along was that politicians and the public didn’t recognize it as a drug. They called it a tradition, a “crop,” and a “legal product.” As though coca and marijuana weren’t crops. As though a product’s legality should decide its morality, instead of the other way around. When it came to smoking, culture overpowered reason.

MUDGE has loved ones (including he who bestowed the appellation itself) who are fanatical anti-smokers, for the most popular reason: they are reformed smokers.

They helped lead the successful (by no means a certainty 8-10 years ago when they started) fight against smoking in public places, starting with restaurants (of course these really are private places open to the public) in our tiny corner of the universe.

And smoking is one of the few vices that MUDGE has never stuck with; maybe because Philip Morris never developed a pralines and cream flavored Marlboro.

But I can’t help agree with Mr. Saletan that perhaps we’ve all gone a bit too far.

The international jihad against tobacco. – By William Saletan – Slate Magazine

I especially enjoyed the creative medicinal use for tobacco near the end of the article:

Instead of indiscriminately vilifying tobacco, we should reengineer it. Bypass the combustion, purge the tar, dial down the nicotine—whatever serves public health. We could even use it to cure people. Two years ago, Henry Daniell, a biologist at the University of Central Florida, proved that an anthrax vaccine could be grown in genetically engineered tobacco. Tobacco was a logical vehicle, he said, because it was prolific and wouldn’t end up in the food supply. Last month, he reported progress in growing a protein to prevent diabetes, but he had to do it in lettuce—a food supply risk—”due to the stigma associated with tobacco.” When the war on smoking has come to this, it’s time to step back and take a deep breath.

Any time you anti-tobacco activists, flush with your victories, are seeking to extend your power toward a new cause, MUDGE has one for you.

One to which I’ll lend all the grandeur and prestige accrued in the 3½ months of this blog: Come on, people, let’s ban the public, and private consumption of zucchini once and for all!

It’s it for now. Thanks,

Computer science and biological science have a lot to teach each other

Stephen Jeffrey

Stephen Jeffrey

THERE is, at the moment, a lot of interest in the idea of artificial life. The ability to synthesise huge screeds of DNA at will means the genomes of viruses can be replicated already, and replicating those of bacteria is not far off. But that merely copies what nature already manages routinely. David Harel of the Weizmann Institute in Israel reckons he can do better. He proposes to recreate living organisms inside a computer.

As with many biologists, his creature of choice is a worm called Caenorhabditis elegans. This tiny nematode (it is just a millimetre long) was the first organism to have its developmental pathway worked out cell by cell and the first multicellular one to have its genome sequenced completely. It is probably, therefore, the best understood animal in biology.

As he told “The next 10 years”, a conference organised by Microsoft Research in Cambridge, England, Dr Harel has been working on a computer model of C. elegans. He hopes this will reveal exactly how pluripotent stem cells—those capable of becoming any sort of mature cell—decide which speciality they will take on. He thinks that a true understanding of the processes involved will be demonstrated only when it is possible to build a simulation that does exactly—but artificially—what happens in nature. With colleagues at New York University and Yale University in America, he is modelling and testing the possibilities.

Indeed, he proposes to evaluate the result using an updated version of the Turing test. This was devised by Alan Turing, an early computer scientist, to identify whether a machine is capable of thought. The original test proposes that a person be presented with a suitable interface—say, a keyboard and a screen—through which to communicate. If the operator cannot tell the difference between talking to another person through this interface and talking to a computer, then the computer can be argued to be thinking. Dr Harel’s version is a little more challenging. He wants to test whether scientists well versed in the ways of C. elegans could tell his computerised version from the real thing. So far, the distinction is obvious, but it may not always remain so.

Silicon biology

Stephen Emmott, who works for Microsoft Research, wonders whether to turn the whole approach on its head. Instead of looking at how computers can mimic creatures, he wants to build computers from biological components. People—and other creatures—are notoriously forgetful and not much good at number crunching compared with their silicon counterparts. But they do have compensating advantages. People excel at reasoning and make much better learning machines than do computers. Dr Emmott reckons that a biological computer might find it easier to cope with problems that have foxed the traditional, silicon variety for decades—such as how to recognise what it is that they see.

Working with Stephen Muggleton of Imperial College, London, he is developing an “artificial scientist” that would be capable of combining inductive logic with probabilistic reasoning. Such a computer would be able to design experiments, collect the results and then integrate those results with theory. Indeed, it should be possible, the pair think, for the artificial scientist to build hypotheses directly from the data, spotting relationships that the humble graduate student or even his supervisor might miss.

Indeed, Luca Cardelli, who also works for Microsoft Research, likens biological cells to computers. He points out that creatures are programmed to find food and to avoid predators. But exactly how the “wetware” of molecular biology works remains a mystery. Dr Cardelli is trying to discover whether it is more like the hardware of electronic circuits or the software of programming languages. He is using statistical techniques—in particular, a method called stochastic pi-calculus—to model how biological systems appear to change with time.

His colleagues, meanwhile, are examining how the spread of diseases such as malaria and AIDS can be thought of as information systems. They are using what used to be called artificial intelligence and is now referred to as machine learning to explore the relationships between the two. All of which raises some interesting philosophical points. If, say, a computer were used to diagnose a patient’s symptoms and recommend treatment, and the result was flawed, could the computer be held responsible? Peter Lipton of the University of Cambridge, who ponders such matters, suggests that such expert systems could indeed be held morally responsible for the consequences of their actions (although the designers of such systems would not necessarily be off the hook). If so, then it is hard to see why computers should not be recognised for good work as well. If Dr Lipton is correct, the race has now begun to see whether the first artificial scientist to win a Nobel prize is based on silicon or biological material.

Computer versions of simple organisms, impossible to differentiate from the real one. A computer that’s a scientist. AIDS as an information system. Easily written; difficult to reflect upon without getting dizzy…

Stories such as this one reinforce my belief that I was born ‘way too soon! But I’m grateful for The Economist for widening my perspectives, as they do every time I click on their site, or crack open the magazine.

It’s it for now. Thanks,
