Welcome to Matt Ridley's Blog

My article in the Times on 13 June 2013

‘We are as gods and have to get good at it,” the Californian ecologist and writer Stewart Brand said recently. Worldwide there has been a sea change in the ecological profession. These days most ecologists recognise that there is no such thing as a pristine wilderness and that the best biodiversity is produced by active management to control some species and encourage others.

My Mind and Matter column in the Wall Street Journal is on abiogenic methane

Coal, oil and gas are "fossil" fuels, right? They are derived from ancient life-forms and are nonrenewable, stored energy, extracted from prehistoric sunlight. In the case of coal and most oil, this is obviously true: You can find fossil tree trunks and leaves in coal seams and chemicals in oil that come from plankton.

But there's increasing doubt about whether all natural gas (which is 90% methane) comes from fermented fossil microbes. Some of it may be made by chemical processes deep within the earth. If so, the implications could be profound for the climate and energy debates.

My Times column here.

I have a confession to make. Last week I held a meeting with representatives of three organisations and offered to raise an issue for them in the House of Lords. They claimed they were charities seeking a smidgin of funding to push forward promising research on a squirrel-pox vaccine, which might help to save the red squirrel from extinction in this country.

Now I begin to wonder if these three charming people were actually disguised investigative reporters who were trying to add my name to that of my three fellow peers who were splashed over the front page of The Sunday Times. Or perhaps they were from a front for the Chinese People’s Liberation Army. (Tony Blair apparently spoke at an event hosted by a front for the latter.) I never checked their credentials or frisked them for hidden cameras.

My latest Mind and Matter column in the Wall Street Journal is on a surprising discovery about antibodies and the immune system:

It isn't often that an entire field of medical science gets turned on its head. But it is becoming clear that immunology is undergoing a big rethink thanks to the discovery that antibodies, which combat viruses, work not just outside cells but inside them as well. The star of this new view is a protein molecule called TRIM21.

Until recently, the conventional wisdom was that the body fights off infection in two separate ways. First is the adaptive immune system, which works outside the cell. It generates antibodies to intercept specific invaders, locking onto them like a tracking missile and preventing them from entering the cell. A second line of defense, the innate immune system, operates within the cell; it is like an expansive air-defense network, blasting away at all invaders.

Update: I have added a reply to a critic of the article below.

I have an article in the Times on the implications of a new estimate of climate sensitivity:

There is little doubt that the damage being done by climate-change policies currently exceeds the damage being done by climate change, and will for several decades yet. Hunger, rainforest destruction, excess cold-weather deaths and reduced economic growth are all exacerbated by the rush to biomass and wind. These dwarf any possible effects of worse weather, for which there is still no actual evidence anyway: recent droughts, floods and storms are within historic variability.

My latest Mind and Matter column in the Wall Street Journal is on infleunza:

Here we go again. A new bird-flu virus in China, the H7N9 strain, is spreading alarm. It has infected about 130 people and killed more than 30. Every time this happens, some journalists compete to foment fear, ably assisted by cautious but worried scientists, and then tell the world to keep calm. We need a new way to talk about the risk of a flu pandemic, because the overwhelming probability is that this virus will kill people, yes, but not in vast numbers.

My latest Mind and Matter column in the Wall Street Journal is on life in space:

A provocative calculation by two biologists suggests that life might have arrived on Earth fully formed—at least in microbe form.

Alexei Sharov of the National Institute on Aging in Baltimore and Richard Gordon of the Gulf Specimen Marine Laboratory in Panacea, Fla., plotted the genome size of different kinds of organisms against their presumed date of origin. Armed with just five data points they concluded that genome complexity doubles every 376 million years in a sort of geological version of Moore's Law of progress in computers.

I have a column in the Times on bitcoins and their implications for private money

Bitcoins — a form of digital private money — shot up in value from $90 to $260 each after Cypriot bank accounts were raided by the State, then plunged last week before recovering some of their value. These gyrations are symptoms of a bubble. Just as with tulip bulbs or dotcom shares, there will probably be a bursting. All markets in assets that can be hoarded and resold — as opposed to those in goods for consumption — suffer from bubbles. Money is no different; and a new currency is rather like a new tulip breed.

Yet it would be a mistake to write off Bitcoins as just another bubble. People are clearly keen on new forms of money safe from the confiscation and inflation that looks increasingly inevitable as governments try to escape their debts. Bitcoins pose a fundamental question: will some form of private money replace the kind minted and printed by governments?

My latest Mind and Matter column in the Wall Street Journal is on junk DNA and on the messed up genome of the HeLa cell.

The usually placid world of molecular biology has been riven with two fierce disputes recently. Although apparently separate, the two conflagrations are converging.

The first row concerns the phrase "junk DNA." Coined in 1972 by the geneticist Susumu Ohno, it is an attempt to explain why vast stretches of animal genomes, far more in some species than in others, seem to serve no purpose. Genes of all kinds and their control sequences make up maybe 9% of the human genome at the very most. The rest may be nonfunctional "junk," mainly there because it is good at getting itself duplicated. Yet the phrase has always caused a surprising amount of offense. Reports of the discrediting of junk-DNA theory have been frequent.

I wrote The Spectator diary column this week:

We’ve discovered that we own an island. But dreams of independence and tax-havenry evaporate when we try to picnic there on Easter Sunday: we watch it submerge slowly beneath the incoming tide. It’s a barnacle-encrusted rock, about the size of a tennis court, just off the beach at Cambois, north of Blyth, which for some reason ended up belonging to my ancestor rather than the Crown. Now there’s a plan for a subsidy-fired biomass power station nearby that will burn wood (and money) while pretending to save the planet. The outlet pipes will go under our rock and we are due modest compensation. As usual, it’s us landowners who benefit from renewable energy while working people bear the cost: up the coast are the chimneys of the country’s largest aluminium smelter — killed, along with hundreds of jobs, by the government’s unilateral carbon-floor price in force from this week.

There were dead puffins on the beach, as there have been all along the east coast. This cold spring has hit them hard. Some puffin colonies have been doing badly in recent years, after booming in the 1990s, but contrary to the predictions of global warming, it’s not the more southerly colonies that have suffered most. The same is true of guillemots, kittiwakes and sandwich terns: northern colonies are declining.

My latest Mind and Matter column in the Wall Street Journal:

A new study by Dirk Helbing at ETH Zurich in Switzerland and colleagues has modeled the emergence of “nice” behavior in idealized human beings. It’s done by computer, using the famous “prisoner’s dilemma” game, in which a prisoner has to decide between cooperating with a comrade to get a mutual reward or avoiding a punishment by being the first of the two to defect to the other side. The Zurich team found that so long as players in the game stay near their (modeled) parents, the birth of a nice guy predisposed to cooperate can trigger “a cascade” of generous acts.

This is a version of an article I published in The Times on 27 March:

The east wind could cut tungsten; the daffodils are weeks behind; the first chiffchaffs are late. It’s a cold spring and the two things everybody seems to agree upon are that there’s something weird about the weather, and it’s our fault. Both are almost certainly wrong.

I have published the following article in the Newcastle Journal (paywalled) today:

My latest Mind and Matter column in the Wall Street Journal:

Obsidian was once one of humankind's most sought-after materials, the "rich man's flint" of the stone-age world. This black volcanic glass fragments into lethally sharp, tough blades that, even after the invention of bronze, made it literally a cutting-edge technology.

Because sources of obsidian are few and far between, obsidian artifacts are considered some of the earliest evidence of commerce: Long-distance movement of obsidian, even hundreds of thousands of years ago, suggests the early stirring of true trade.

I have the following article in the Times on 15 March:

Move over shale gas, here comes methane hydrate. (Perhaps.) On Tuesday the Japanese government’s drilling ship Chikyu started flaring off gas from a hole drilled into a solid deposit of methane and ice, 300 metres beneath the seabed under 1000 metres of water, 30 miles off the Japanese coast.

My latest Mind and Matter column for the Wall Street Journal is on the prospect of de-extinction, especially the passenger pigeon.

Extinct species are gone forever. Or are they? For some time now the dream of re-creating something like a mammoth from its DNA has been floating about on the fringes of the scientific world (and in movies like "Jurassic Park") without being taken seriously.

My latest Mind and Matter column in the Wall Street Journal is about what happened to the cology of North America after the asteroid impact of 66 million years ago:

Last week, just as a meteorite exploded over Russia, I used this space for an email to Charles Darwin, wherever he is. I told him about the now overwhelming evidence for an asteroid impact having caused the extinction of dinosaurs. I thought he would be interested because it is a striking exception to his "uniformitarian" assumption that, in the past, evolution was shaped by the same forces still operating on Earth today.

My latest Mind and Matter column for the Wall Street Journal, published the day after a big asteroid missed the earth by 17,000 miles and a smaller one blew out windows in Russia, is about the huge one that extinguished the dinosaurs just over 66 million years ago:

The future has a richer past than the past did. By this I mean that one of the great benefits of modern science is that it enriches our knowledge of the past. Imagine how thrilled Charles Darwin would have been to learn this week that it's now all but certain that the extinction of the dinosaurs was caused by an asteroid (much bigger than the one that missed us this week) slamming into Mexico about 66,038,000 years ago. In fact, I might send him an email to explain.

It's not a race, exactly, but there's an intriguing uncertainty about whether a former U.S. president or a software magnate will cause the next deliberate extinction of a species in the wild. Will Jimmy Carter eradicate Guinea worm before Bill Gates eradicates polio?

It is more than a third of a century since a human disease was extinguished. The last case of smallpox was in 1977, and in those days health experts expected other diseases to follow smallpox quickly into oblivion. Polio has repeatedly disappointed campaigners by hanging on, though it now affects less than 1% as many people as at its peak in the 1950s.

The generosity of Bill Gates has done much to speed the decline of polio, and he and most experts now see its end within six years at most. India, 10 years ago the worst-affected country, has been polio-free since 2011, and only three countries still host the virus: Pakistan, Afghanistan and especially Nigeria. Though the murder of nine polio vaccinators in Pakistan by Islamists in December was a tragic setback, last year there were just 222 new polio cases world-wide.

My latest Mind and Matter column is on the esoteric topic of insect navigation:

A friend who once studied courtship in dung beetles alerted me last week to a discovery. On moonless nights, African scarab beetles, which roll balls of dung, can use the Milky Way to navigate in fairly straight lines away from dung piles, thus avoiding other dung beetles keen to steal their dung balls. "Now this is real science, simple, fascinating and completely wonderful," enthused my friend.

Marie Dacke of Lund University in Sweden and her colleagues put dung beetles inside a planetarium at Wits University in South Africa with a pile of dung, and with or without little caps over their eyes. The results of the beetles' peregrinations clearly showed that being able to see the stars keeps the beetles relatively straight, even if just the Milky Way is projected overhead without other stars. This is the first demonstration of star navigation by insects and of Milky Way navigation by any animal.

Here's my latest Mind and Matter column in the Wall Street Journal:

A war within anthropology over the causes of war itself seems to be reaching resolution. The great ethnographer of the gardener-hunter Yanomamo Indians of Venezuela, Napoleon Chagnon, has long been battling colleagues over whether men in prestate societies go to war over protein or women. Next month he'll publish a memoir, "Noble Savages," detailing (as the subtitle puts it) "My Life Among Two Dangerous Tribes-the Yanomamo and the Anthropologists." This is a good time to look back at how his argument has fared.

My latest Mind and Matter column in the Wall Street Journal:

Not only is the capacity for forming large social networks in monkeys partly genetic, but some of the genes that affect this ability may now be known. So suggests a new study of an isolated population of free-living macaques on an island off Puerto Rico.

Scientists at the Massachusetts Institute of Technology and Rockefeller and Harvard universities have found a new method of editing DNA with great precision. This and another new technique mean that scientists can now go into a cell, find a particular sequence in the genome and change that sequence by a single letter.

Just to get your mind around this feat, imagine taking about 5,000 different novels and reprinting them in normal font size on 23 very long cotton ribbons. Since each word takes up about half an inch, the ribbons, placed end to end, would stretch for roughly three million miles-120 times around the world. But to be a bit more realistic, twist and tangle the ribbons so much that they only go around the planet once.

One of the books written on your ribbons is "A Tale of Two Cities," but you don't even know which ribbon it is on, let alone where on that ribbon. Your task is to find the clauses "It was the beast of times, it was the worst of times" and correct the misprint.

Well done, Mark Lynas, for changing his mind over genetically modified food.

Here's Mark Lynas on those who still oppose GM food: "I look forward to their opening up an honest and self-critical debate on this, rather than attacking others like myself who challenge green orthodoxy where it likely harms society and the environment."

Here's Mark Lynas on wind power: "Matt Ridley's massive Spectator anti-wind rant seems completely fact-free. Any references to back this up, @mattwridley?" [There were scores of facts and references, starting with my assertion that wind power provides 0.3% of the UK's total energy, a fact that Lynas challenged, then called specious, then conceded].

My latest Mind and Matter column in the Wall Street Journal is on the greening of the planet:

Did you know that the Earth is getting greener, quite literally? Satellites are now confirming that the amount of green vegetation on the planet has been increasing for three decades. This will be news to those accustomed to alarming tales about deforestation, overdevelopment and ecosystem destruction.

I have an op-ed in the Times on how even a global optimist can foresee absolute as well as relative decline for Europe if it continues to emulate the Ming Empire:

A "rational optimist" like me thinks the world will go on getting better for most people at a record rate, not because I have a temperamental or ideological bent to good cheer but because of the data. Poverty, hunger, population growth rates, inequality, and mortality from violence, disease and weather - all continue to plummet on a global scale.

But a global optimist can still be a regional pessimist. When asked what I am pessimistic about, I usually reply: bureaucracy and superstition. Using those two tools, we Europeans seem intent on making our future as bad as we can. Like mandarins at the court of the Ming emperors or viziers at the court of Abbasid caliphs, our masters seem determined to turn relative into absolute decline. It is entirely possible that ten years from now the world as a whole will be 50 per cent richer, but Europeans will be 50 per cent poorer.

What better subject for the origin of a new year than the origin of life itself? A new paper claims to have nailed down at last the conditions, location and path by which life started, slicing through two Gordian knots.

Knot No. 1 is the chick-and-egg problem of energy. Living things burn energy at a furious rate to stay alive. Every time a bacterium divides, it uses up 50 times its own mass of energy-currency molecules (called ATP)-and that's with efficient and specialized modern protein machinery to do the job. When starting out, life would have been a far more wasteful process, needing more energy, yet would have had none of its modern machinery to harness or store energy.

Knot No. 2 is entropy. Life uses energy to make order out of chaos. So the putative location preferred by previous evolutionists-Alexander Oparin's primordial soup in Charles Darwin's "warm little pond" with a little lightning-is just too unconstrained: Life would just keep dissolving away before it got started.

I published an op-ed in the Wall Street Journal on the subject of climate sensitivity.

Here are:

1. The article

My latest Mind and Matter column in the Wall Street Journal is on peak farmland, a more plausible prediction than peak oil.

It's a brave scientist who dares to announce the turning point of a trend, the top of a graph. A paper published this week does just that, persuasively arguing that a centurieslong trend is about to reverse: the use of land for farming. The authors write: "We are confident that we stand on the peak of cropland use, gazing at a wide expanse of land that will be spared for Nature."
