Generally, junior professors write long and unsolicited emails
to senior professors, who reply with short ones after a delay; the
juniors then reply quickly and at length. This is not because the
seniors are busier, for they, too, write longer and more punctually
when addressing their deans and funders, who reply more briefly and
tardily. The asymmetry in length and speed of reply correlates with
The Times has published my op-ed on shale gas:
It is now official: drilling for shale gas by
fracturing rock with water may rattle the odd teacup, but is highly
unlikely to cause damaging earthquakes. That much has been obvious
to anybody who has followed the development of the shale gas
industry in America over the past ten years. More than 25,000 wells
drilled have caused a handful of micro-seismic events that can
barely be felt.
The two rumbles that resulted from drilling a well near
Blackpool last year were tiny. To call a two-magnitude tremor an
earthquake is a bit like calling a hazelnut lunch. Such tremors
happen naturally more than 15 times a year but go unnoticed and
they are a common consequence of many other forms of underground
work such as coalmining and geothermal drilling. Earthquakes caused
by hydroelectric projects, in which dams load the crust and
lubricate faults, can be much greater and more damaging. The
Sichuan earthquake that killed 90,000 in 2008 was probably caused
by a dam.
After a break of two weeks, here is my latest Mind and Matter column in
the Wall Street Journal:
April 25 is World Malaria Day, designed to draw attention to the
planet's biggest infectious killer. The news is generally good.
Never has malaria, which is carried by the Anopheles mosquito, been
in more rapid retreat. Deaths are down by a third in Africa over
the past decade alone, and malaria has vanished from much of the
world, including the U.S.
As so often happens in the battle against disease, however,
evolution aids the enemy. The selection pressure on pathogens to
develop resistance to new drugs is huge. In recent weeks, the
emergence on the Thai-Myanmar border of malaria strains resistant
to artemisin, a plant-derived drug, have led to pessimistic
headlines and reminders of the setback caused by resistance to the
drug chloroquine, which began in the 1950s.
A new study of the Great Barrier Reef will
apparently confirm what I argued in The Rational Optimist that
local pollution and over-fishing are a much greater threat to coral
reefs than either climate change or changing alkalinity (sometimes
wrongly called acidification).
The actual paper will appear in Current Biology,
but this is from the press release from James Cook University (I
hate it when scientists announce their results by press release
before the journal article is available).
Update: here's the article in press, but behind a
