In our 24/7 culture, sleep loss is a major problem. Back in 1942, we averaged almost 8 hours of sleep a night — now that’s down to 6.8. (Seven to 9 hours per night are what’s generally recommended.) Almost 40 per cent of Americans get less than seven hours of sleep a night, a recent Gallup poll found, and an estimated 70 million Americans have a sleep disorder. Everyone knows that it’s important to get enough sleep — but you may not realise just how many things can go wrong when you don’t.

In the library world, access to information is a human right, not to be tampered with or controlled in any way. The books that line the shelves have been carefully selected by a trained librarian to offer the reader a balanced approach to all topics — that is, we try to provide all points of view, whether or not we personally agree with them.

Strap the Roman visitor into the passenger seat of something like this. Start the engine. Explain to him that there's a box full of a special sort of oil that's burning in constant tiny explosions, making that thing in front that's like three sword blades fastened together spin around 2700 times per minute.

Most nectar-eating bats hover in front of flowers and lap like crazy to shovel high-calorie goodness down their throats. But when some species of South American leaf-nosed bats cosy up to a flower, they just stick their tongues in and leave them there. They're eating, but their tongues don't seem to be moving at all. It's weird.
