My Times column on the revolution in protein and DNA diagnosis:
As happens in the media, the excitement generated last week by the headline that cancer could be detected in the blood was overdone. The results announced in Science magazine are a long way short of meaning that the earliest signs of cancer can be detected in people with no symptoms: the 70% success rate in finding DNA from 16 cancerous genes was in people already diagnosed with serious cancers. False hopes may have been raised.
But behind the headline, there is little doubt that a revolution in diagnostics is happening. Till now, the slow process of culturing infectious agents to identify them has not changed much since the days of Louis Pasteur. It is becoming increasingly possible to identify the precise virus, bacterium, drug-resistant strain, antibody or telltale molecule that defines exactly what is wrong with somebody, quickly and without invasive procedures or lengthy cultures in distant labs. Yet Britain is lagging behind comparable countries in joining that revolution.
My Times column on the government's 25-year plan for the environment:
The government’s 25-year environment plan is more than a piece of virtue signalling, despite its chief purpose being to persuade the young to vote Conservati(ve)onist. It is full of sensible, apolitical goals and in places actually conveys a love of the natural world, which is not always the case with such documents.
An expanded version of my recent Times column on ice ages:
Record cold in America has brought temperatures as low as minus 44C in North Dakota, frozen sharks in Massachusetts and iguanas falling from trees in Florida. Al Gore blames global warming, citing one scientist to the effect that this is “exactly what we should expect from the climate crisis”. Others beg to differ: Kevin Trenberth, of America’s National Centre for Atmospheric Research, insists that “winter storms are a manifestation of winter, not climate change”.
Forty-five years ago a run of cold winters caused a “global cooling” scare. “A global deterioration of the climate, by order of magnitude larger than any hitherto experienced by civilised mankind, is a very real possibility and indeed may be due very soon,” read a letter to President Nixon in 1972 from two scientists reporting the views of 42 “top” colleagues. “The cooling has natural causes and falls within the rank of the processes which caused the last ice age.” The administration replied that it was “seized of the matter”.
My Times column on AI and jobs:
In the early 1960s, at the Massachusetts Institute of Technology, there was a disagreement about what computers would achieve. One faction, led by John McCarthy and Marvin Minsky, championed “artificial intelligence”, believing that computers would gradually replace human beings. The other, led by Norbert Wiener and JCR Licklider, the man who oversaw the creation of the internet’s precursor, championed “human-computer symbiosis”, believing that computers would augment human beings.
