Do Polar Bears Get Lonely?, Edited by Mick O'Hare

Following on from the ludicrously popular Why Don't Penguins' Feet Freeze, this latest collection of strange and intriguing posers from the New Scientist's "Last Word" column achieves a scientifically improbable feat: it continues to feed the appetite for weird science without seeming to scrape the bottom of the barrel.

Including an ashamed correction to the previous book's answer about cracked glasses, some useful information about garlic breath and some less useful stuff about which parts of a live human body to eat, this is sure to be another Christmas hit.
