  • The five myths about fracking

    Published on: Friday, 16 August, 2013

    Wind power does more environmental harm

    My Times column on the environmental effects of fracking and wind power:

    It was the American senator Daniel Patrick Moynihan who once said: “You are entitled to your opinions, but not to your own facts.” In the debate over shale gas – I refuse to call it the fracking debate since fracking has been happening in this country for decades – the opponents do seem to be astonishingly cavalier with the facts.

    Here are five things that they keep saying which are just not true. First, that shale gas production has polluted aquifers in the United States. Second, that it releases more methane than other forms of gas production. Third, that it uses a worryingly large amount of water. Fourth, that it uses hundreds of toxic chemicals. Fifth, that it causes damaging earthquakes.

    The deliberate frustration of golden rice is a humanitarian crime

    Belated posting of my recent Times column on golden rice with links:

    It was over harlequin ducks that we bonded. Ten years ago, at a meeting in Monterey, California, to celebrate the 50th anniversary of the discovery of the structure of DNA, I bumped into the German biologist Ingo Potrykus watching harlequin ducks in the harbour before breakfast. Shared enthusiasm for bird watching broke the ice.

    I knew of him, of course. He had been on the cover of Time magazine for potentially solving one of the world’s great humanitarian challenges. Four years before, with his colleague Peter Beyer, he had added three genes to the 30,000 in rice to help to prevent vitamin A deficiency, one of the most preventable causes of morbidity and mortality in poor countries with rice-dominated diets. They had done it for nothing, persuading companies to waive their patents, so that they could give the rice seeds away free. It was a purely humanitarian impulse.

  • Hadrian's wall was a marvellous mistake; so is HS2

    Published on: Friday, 26 July, 2013

    On the opportunity costs of huge infrastructure projects

    My latest column in The Times:

    This is an article about a railway, but it begins with a wall; bear with me. I live not far from the line of Hadrian’s Wall and I often take visitors to marvel at its almost 1,900-year-old stones. That the Romans could build 80 miles of dressed stone fortification, 15ft high and 9ft wide, over crags and bogs with a small fort every mile, is indeed a marvel. It was one of Rome’s most expensive projects.

    Yet I often ask visitors as they marvel: did it work? The answer is no. The Roman garrison was too strung out to defend the whole thing at once. Within 30 years it had been successfully attacked by the barbarians; within 40 it had been abandoned for a new wall in Scotland; when that did not work and Hadrian’s Wall became the boundary again, it was overrun by barbarians several times. Did it exclude or pacify the tribes of northern Britain? I doubt it.

  • Alan Turing, a great scientist

    Published on: Saturday, 20 July, 2013

    More than just a war hero and victim of persecution

    My Times column:

    Tomorrow the House of Lords gives a second reading to Lord Sharkey’s Bill to pardon Alan Turing, the mathematician, computer pioneer and code-cracking hero of the Second World War.

    In 1952 Turing was prosecuted for being gay (he had reported a burglary to the police and made it no secret that the burglar was a friend of his consensual lover). Convicted of “gross indecency” he was offered prison or oestrogen injections to reduce his libido; he chose the latter but then committed suicide at the age of 41.

  • Lower costs mean higher spending in healthcare

    Published on: Friday, 12 July, 2013

    The Jevons paradox in medical technology

    My column in The Times on healthcare costs:

    Babies got cheaper this week. Twice. First, Belgian scientists announced that their new method has the potential to cut the costs of some in-vitro fertilisation treatments from £5,000 to below £200. Their cut-price recipe requires little more than baking soda and lemon juice in place of purified carbon dioxide gas to maintain acidity when growing an embryo in a lab before implanting it.

    Second, a baby called Connor was born after 13 of his parents’ embryos had their genomes analysed using next-generation DNA-sequencing techniques in an Oxford laboratory. Only three of the embryos were found to have the right chromosome number, and one of these “normal” embryos was then implanted in his mother. This new approach, made possible by the rapidly falling cost of DNA sequencing, promises to cut the number of failures during IVF, reducing both cost and heartache.

  • Nobody ever calls the weather average

    Published on: Friday, 12 July, 2013

    The extreme weather scam exposed in a new book

    Part of the problem was that some time towards the end of the first decade of the 21st century it became clear that the Earth's average temperature just was not consistently rising any more, however many "adjustments" were made to the thermometer records, let alone rising anything like as rapidly as all the models demanded.

    So those who made their living from alarm, and by then there were lots, switched tactics and began to jump on any unusual weather event, whether it was a storm, a drought, a blizzard or a flood, and blame it on man-made carbon dioxide emissions. This proved a rewarding tactic, because people - egged on by journalists - have an inexhaustible appetite for believing in the vindictiveness of the weather gods. The fossil fuel industry was inserted in the place of Zeus as the scapegoat of choice. (Scientists are the priests.)

    The fact that people have short memories about weather events is what enables this game to be played. The long Australian drought of 2001-7, the Brisbane floods of 2009-10 and the angry summer of 2012-13 stand out in people's minds. People are reluctant to put them down to chance. Even here in mild England, people are always saying "I have never known it so cold/hot/mild/windy/wet/dry/changeable as it is this year". One Christmas I noticed the seasons had been pretty average all year, neither too dry nor too wet nor too cold nor too warm. "I have never known it so average," I said to somebody. I got a baffled look. Nobody ever calls the weather normal.

  • I may follow the crowd, but not because it's a crowd

    Published on: Sunday, 07 July, 2013

    Evidence, not consensus, is what counts

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

    Last week a friend chided me for not agreeing with the scientific consensus that climate change is likely to be dangerous. I responded that, according to polls, the "consensus" about climate change only extends to the propositions that it has been happening and is partly man-made, both of which I readily agree with. Forecasts show huge uncertainty.

    Besides, science does not respect consensus. There was once widespread agreement about phlogiston (a nonexistent element said to be a crucial part of combustion), eugenics, the impossibility of continental drift, the idea that genes were made of protein (not DNA) and stomach ulcers were caused by stress, and so forth—all of which proved false. Science, Richard Feyman once said, is "the belief in the ignorance of experts.

  • The dash for shale oil will shake the world

    Published on: Saturday, 06 July, 2013

    Oil prices look set to fall as America exploits a shale cornucopia

    My Times column:

    Exciting as Britain’s latest shale gas estimate is — 47 years’ supply or more — it pales beside what is happening in the United States. There shale gas is old hat; the shale oil revolution is proving a world changer, promising not just lower oil prices worldwide, but geopolitical ripples as America weans itself off oil imports and perhaps loses interest in the Middle East.

    One of the pioneers of the shale gas revolution, Chris Wright, of Liberty Resources, was in Britain last month. It was he and his colleagues at Pinnacle Technologies who reinvented hydraulic fracturing in the late 1990s in a way that unlocked the vast petroleum resources in shale. Within seven years the Barnett shale, in and around Forth Worth, Texas, was producing half as much gas as the whole of Britain consumes. And the Barnett proved to be a baby compared with other shales.

  • The myth that choice overload is a cause of great misery

    Published on: Saturday, 06 July, 2013

    Fashionable attacks on choice are not supported by good evidence

    I have an article in Spiked! on the the tyranny of consumer choice:

    This summer at TED Global in Edinburgh, a lively networking conference, there was a talk on one of the true and terrible scourges of the modern world. This is a bit of a theme for TED. The same scourge was bravely but mercilessly exposed at TED Global three years ago in Oxford and nine years ago at the ur-TED itself in California. All three talks went down well with the hip folk who attend TED meetings. They nodded in agreement that this scourge must end, and soon.

    The scourge in question? The thing that deserved as prominent a castigation as disease and poverty and tyranny? Too much choice. Yes, the pressing and urgent issue we face is that when we enter a supermarket, we find tens of brands of cereal and it is making us – wait for it – anxious. Oh woe.

  • Curing cancer is harder than preventing it

    Published on: Sunday, 30 June, 2013

    Genomics helps head off cancer, but cures remain elusive

    My column in The Times:

    Preventing cancer is proving a lot easier than curing it. The announcement that the NHS will fund five-year courses of the drugs tamoxifen or raloxifene for healthy women who are genetically predisposed to get breast and ovarian cancer is overdue. The US has been doing “chemo-prevention” for some time and clinical trials have confirmed that the benefits comfortably outweigh the side-effects. Tens of thousands of deaths a year could be averted.

    This is another incremental advance in the prevention of cancer that began with the gradual recognition (resisted, ironically, by some of those fighting pesticides in the late 1950s) that tobacco smoke was a chief cause of lung cancer. Mainly thanks to such prevention, along with early diagnosis, surgery and some treatments, deaths from cancer, adjusted for age, are falling.

  • The Tabarrok curve

    Published on: Sunday, 23 June, 2013

    Striking a balance between intellectual property and freedom to innovate

    The economist Arthur Laffer is reputed to have drawn his famous curve—showing that beyond a certain point higher taxes generate lower revenue—on a paper napkin at a dinner with Dick Cheney and Donald Rumsfeld in the Washington Hotel in 1974.

    Another economist, Alex Tabarrok of George Mason University, last year drew a similar curve on a virtual napkin to argue that, beyond a certain point, greater protection for intellectual property causes less innovation. He thinks that U.S. patent law is well beyond that optimal point.

    Last week the Supreme Court came out against the patenting of genes, on the grounds that they are discoveries, not inventions, though it did allow that edited copies of the DNA of a breast cancer gene should be seen as invented diagnostic tools. Dr. Tabarrok thinks that decision and other recent rulings are nudging patent law back in the right direction after a protectionist drift in the 1980s and '90s.

    Making electricity from burning wood is bad for the economy and the environment

    My column in the Times on 20 June 2013:

    In the Energy Bill going through Parliament there is allowance for generous subsidy for a huge push towards burning wood to produce electricity. It’s already happening. Drax power station in Yorkshire has converted one of its boilers to burn wood pellets instead of coal; soon three of its six boilers will be doing this and the power station will then be receiving north of half a billion pounds a year in subsidy. By 2020, the Government estimates, up to 11 per cent of our generating capacity will be from burning wood.

    Published on: Monday, 17 June, 2013

    In the absence of predators to control lesser predators, people have a role

    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.

  • Non-fossil fuels

    Published on: Saturday, 08 June, 2013

    Abiogenic methane made in the mantle from carbonate?

    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.

  • Who will lobby for the poor old taxpayer?

    Published on: Saturday, 08 June, 2013

    It's what politicians will do unbribed that's the bigger scandal

    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.

  • TRIM21 turns immunity upside down

    Published on: Tuesday, 28 May, 2013

    Unexpectedly, antibodies work inside cells to defeat pathogens

    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.

  • The implications of lower climate sensitivity

    Published on: Monday, 20 May, 2013

    Global warming will probably be a net benefit for several decades

    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.

    Why influenza keeps failing to live up to pessimistic forecasts

    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.

  • Did life arrive on earth as microbes?

    Published on: Sunday, 28 April, 2013

    A speculative idea that we could be the history of life's second chapter

    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.

  • The bitcoin bubble and Birmingham tokens

    Published on: Friday, 19 April, 2013

    Private innovation in currencies is a good thing

    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?

  • Junk DNA and HeLa cells

    Published on: Sunday, 14 April, 2013

    Two fierce arguments about DNA

    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.

  • Spectator Diary April 2013

    Published on: Monday, 08 April, 2013

    The cold spring weather and what it means

    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.

  • Nice or nasty by nature?

    Published on: Sunday, 31 March, 2013

    Under some conditions co-operation evolves

    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.

  • It's weather, not climate

    Published on: Friday, 29 March, 2013

    Variability matters more than trend

    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.

  • Obsidian chronicles ancient trade

    Published on: Sunday, 17 March, 2013

    The collapse of the Akkadian empire laid bare by isotopes

    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.

    Methane hydrate joins shale gas and deep sea gas

    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.

  • Jurassic pigeon- the drive to revive extinct species

    Published on: Saturday, 02 March, 2013

    De-extinction is much closer than it was

    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.

  • After the asteroid impact

    Published on: Sunday, 24 February, 2013

    How North America got its plants and animals back

    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.
