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.

Episode 6: best and worst! The games, gadgets, movies and science stories that most caught our attention in 2015. We also chat with renowned theoretical physicist and string theorist, professor Brian Greene.
Personally, I need breakfast. Almost every morning, I wake up early feeling hungry, and it’s only once I banish my morning hunger that I’m ready to fire. By mid-morning, I take a break and enjoy a snack.
I’ve used a personal anecdote because it’s likely that eating breakfast – or skipping it – may simply reflect a personal preference for timing food intake. Not everyone enjoys eating first thing in the morning. But your first choice of foods may contribute to an overall healthy diet.
If the notion that humans will one day ascend into orbit on a rope of ultra strong carbon nanofibres sounds a bit out of this world, then you're going to love the latest dazzling twist: our future space elevators might actually be built of diamond.
Yesterday the Royal Swedish Academy of Sciences awarded the Nobel Prize in Chemistry to Tomas Lindahl, Aziz Sancar, and Paul Modrich for their work in mapping out how cells repair damaged DNA. Their research improved our understanding of how our own cells work and helped in the development of cancer treatments, but what does it all really mean?
This past Monday, people from around the world aimed their cameras upwards in hopes of catching a glimpse of the "blood moon" lunar eclipse. But as this 19th century manuscript shows, it's a phenomenon that's been chronicled long before the advent of camera phones and telescopic lenses.
Going to Pluto was incredible, but as we continue to soak in the glorious images, NASA's already trying to figure out which celestial target to hit next. The space agency revealed five finalist concepts this week, including missions that would take us to Jupiter's asteroids and the surface of Venus.
Remember a few weeks back, when Elon Musk explained how we ought to nuke Mars to warm it up? Well, the billionaire was really just speaking off the cuff, and so during a SolarCity launch event in Times Square yesterday, he decided he ought to clarify.
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.
We’ve known for a long time that there’s water on Mars. Now we know – thanks to NASA’s latest announcement – that some of it is at the surface.
In a sad turn of events, CSIRO's RV Investigator, a dedicated marine research vessel that winded up construction and testing earlier this year, will now spend a few months under the employ of BP and Chevron sniffing out black gold... while also studying the ocean and sea floor.
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.
