latest Mind and Matter column in the Wall Street Journal:
Human beings love sharing. We swap, collaborate, care, support,
donate, volunteer and generally work for each other. We tend to
admire sharing when it's done for free but frown upon it-or
consider it a necessary evil-when it's done for profit. Some think
that online, we're at the dawn of a golden age of free sharing, the
wiki world, in which commerce will be replaced by mass communal
sharing-what the futurist John Perry Barlow called "dot
My latest Mind and Matter column in the Wall
If you write about genetics and evolution, one of the commonest
questions you are likely to be asked at public events is whether
human evolution has stopped. It is a surprisingly hard question to
I'm tempted to give a flippant response, borrowed from the
biologist Richard Dawkins: Since any human trait that increases the
number of babies is likely to gain ground through natural
selection, we can say with some confidence that incompetence in the
use of contraceptives is probably on the rise (though only if those
unintended babies themselves thrive enough to breed in turn).
Latest Mind and Matter column in the Wall Street Journal
This week saw the announcement of the latest conclusions of
the Copenhagen Consensus, a project founded by Bjørn Lomborg in
which expert economists write detailed papers every four years and
then gather to vote on the answer to a simple question: Imagine you
had $75 billion to donate to worthwhile causes. What would you do,
and where should we start?
Mind and Matter column from the Wall Street Journal:
Being maltreated as a child can perhaps affect you for life. It
now seems the harm might reach into your very DNA. Two recently
published studies found evidence of changes to the genetic material
in people with experience of maltreatment. These are the tip of an
iceberg of discoveries in the still largely mysterious field of
"epigenetic" epidemiology-the alteration of gene expression in ways
that affect later health.
My latest Mind and Matter column for the Wall
Peter Pringle's new book "Experiment Eleven" documents a shocking
scandal in the history of medicine, when Albert Schatz, the
discoverer of streptomycin, was deprived of the credit and the
Nobel Prize by his ambitious boss, Selman Waksman. Streptomycin was
and is a miraculous cure for tuberculosis.
Yet the near disappearance of tuberculosis from the Western
world, where it was once the greatest killer of all, owes little to
streptomycin. Mortality from TB had already fallen by 75% in most Western
countries by 1950, when streptomycin became available, and the rate
of fall was little different before and after. Scarlet fever,
pneumonia and diphtheria all declined rapidly long before their
cures were introduced.
My latest Wall Street Journal column is on the technology of fly fishing
Moore's Law is the leitmotif of the modern age: Incessant
improvements in communication and computing are accompanied by
incessant drops in price. Yet some quite low-tech devices are also
experiencing Moore's Laws of their own, especially those that use
new materials. Even something as mundane as fishing rods.
