Reptile mammal

Mammals and reptiles have different strategies for raising their young. So do scientists.

Basically, it’s a question of risk. You can invest a lot in a very small number of offspring, or you can produce a ton of them but not leave much love to go around*. The former strategy gives that lucky sprog the best possible start, but carries a much higher penalty for the parents if things don’t work out; the latter lessens the damage inflicted by losing one or more offspring, but naturally makes them somewhat more disposable. Bad news if you’re one of the ones that doesn’t make it.

That’s Nature, but the same dynamic gets played out in research labs the world over. Continue reading

Crick, he said, seemed to exemplify the worst aspects of the British system, namely “all talk and no action”.

High-minded gentlemen scientists sitting around in armchairs in club rooms doing thought experiments, and occasionally deigning to publish their insights. Theorising, theorising, theorising. Very little actual “doing”.

That’s what the work ethic replaced. Why do the thought experiment when you could do the actual experiment? And the powerhouse performance of American academia in the 20th century is all the validation that’s needed of that more practical approach.

But there’s a sense now that the pendulum may have swung too far the other way. Continue reading
