“Although a few antibiotics have been toughened up a bit, the pharmaceutical industry hasn’t given us an entirely new antibiotic since the 1970s.”

Britain still has the most reliably beautiful countryside of anywhere in the world. I would hate to be part of the generation that allowed that to be lost.

If you were designing an organism to look after life in our lonely cosmos, to monitor where it is going and keep a record of where it has been, you wouldn’t choose human beings for the job.

It was one of those sumptuous days when the world is full of autumn muskiness and tangy, crisp perfection: vivid blue sky, deep green fields, leaves in a thousand luminous hues. It is a truly astounding sight when every tree in a landscape becomes individual.

Language is more fashion than science, and matters of usage, spelling and pronunciation tend to wander around like hemlines.

This much may have happened many times before. But this ancestral packet did something additional and extraordinary. It cleaved itself and produced an heir.
