Steve Connor: Deadly fault lines that run down the spine of Italy

This region of Italy has a long history of earthquakes dating from long before classical times. It is one of the most seismically active regions of Europe, essentially due to the collision of the tectonic plates of Africa and Europe which pushed up the Apennine mountain range, the geological "backbone" of Italy.

Journey Into Space, By Toby Litt

When I was a child, I had a nightmare about space; nothing I've ever read or seen since has recaptured the pitiless immensity of it. Until this novel. In the not-too-distant future, a spaceship is journeying through deep space carrying 100 would-be colonists – or rather, the ancestors of would-be colonists – for the voyage to the destined planet will take generations.

An Atlas of Impossible Longing, by Anuradha Roy

A history at risk as the waters rise

Paperback: Selected Poems, by Martin Newell

Readers with fond memories of Newell's long innings as the pop poet of this parish will be delighted to find not just biting satirical verse but lyrical, reflective and personal pieces here – a range as broad and bracing as the East Anglian marshlands he adores. Buffs will tick off echoes (Larkin, Betjeman, Kipling, Auden...) but he's his own – Essex – man, cussed and tender and just a bit mystical, too. Germaine Greer (yes, really) warmly salutes him in her preface. He deserves it.

The Kiwi's Egg: Charles Darwin and natural selection, By David Quammen

Darwin came up with the theory of evolution, right? Wrong. Evolution, if not in the scientific mainstream, was part of the common intellectual currency of his time. His own grandfather espoused a version of it. What Darwin proposed was the blind, purposeless and godless mechanism by which it worked: natural selection.
