My Times column on the Chan-Zuckerberg initiative in basic medical science:
Mark Zuckerberg, chief executive of Facebook, and his wife Priscilla Chan, a paediatrician, have announced their intention to spend $3 billion over ten years on medical research. Having met them last year, I thought I would take the liberty of making a suggestion as to how they spend their money.
My Times column on statins, snus and vaping:
One of the most salutary examples of people in authority getting risks wrong is a paper written in 1955 by the first head of the environmental cancer section of the US National Cancer Institute, Wilhelm Hueper. The title was “lung cancers and their causes” and he was absolutely convinced that “cigarette smoking is not a major factor in the causation of lung cancer”, because he thought this was a cheap shot by the chemical industry to divert attention away from pesticides.
We now know that smoking is a major cause of lung cancer, whereas pesticides are not. History is littered with example of experts being too reassuring about some risks, too alarmed about others. Washing hands between dissecting women who died in child birth and delivering babies? No risk, said the nineteenth century medical establishment, ostracizing Ignaz Semelweiss who had had the temerity to suggest otherwise. Dietary fats cause heart attacks, insisted the medical establishment for the best part of five decades till very recently. It was once the consensus that tonsils should be removed; no longer.
My essay on invasive species in the Wall Street Journal:
In July, the New Zealand government announced its intention to eradicate all rats, stoats and possums from the entire country by 2050 to save native birds such as the kiwi. It’s an ambitious plan, perhaps impossible to pull off with the methods available today, but it’s a stark reminder that invasive alien species today constitute perhaps the greatest extinction threat to animal populations world-wide.
Birdlife International, a charity that works to save endangered birds, reckons that of the 140 bird species confirmed to have gone extinct since 1500, invasive alien species were a factor in the demise of at least 71—an impact greater than hunting, logging, agriculture, fire or climate change.
