Editor's note

You'd think Winston Churchill would have been occupied with thoughts of battle on the eve of the second world war. But Britain's most famous prime minister found some time in 1939 to sit down and write an essay about alien life. The essay, recently unearthed in MIssouri, was remarkably prescient, writes Elizabeth Tasker, and holds lessons for the present day.

We've also brought you stories this week on the vampire bats that love to drink human blood, the stunning public poetry of Pakistan, and the ghostly apparitions of India's Doon Valley.
