Researchers from MIT have developed a wireless, artificially intelligent sensor that can detect the various stages of sleep, including rapid eye movement — the sleep stage associated with dreaming. The non-invasive system could change the way clinicians diagnose sleep disorders and other health complications.

Touchscreen devices like smartphones and tablets are now fixtures of many households, so it comes as little surprise to learn that young children who don't work or go to school are among their most active users. In the first study of its kind, researchers have learned that infants and toddlers who spend more time on these devices sleep less at night. It's a troubling finding, but the reasons for these sleep disruptions are still unclear.

Fancy computer phones are great. They let us communicate, work, document, learn, complain, order dinner, find consensual sex friends and plenty of other fun things. If I could attach myself to my phone with some sort of strange, dystopian umbilical cord-like apparatus, I would.

Owing to some horrendously long flight times, scientists have speculated that certain birds are capable of sleep during flight. A remarkable new experiment by an international team of researchers has now proven this to be true, showing that birds can catch a snooze while hitching a ride on rising air currents.

Video: Do you know what a sleeping great white shark looks like? It's never been seen before. Until now. A robotic submersible captured the first-ever footage of a great white taking a nap, and you can see it innocently catch some zzzs with its mouth hanging wide open. It looks maybe seven per cent less frightening than a great white that's awake.

Video: When you're counting sheep jumping over a fence to help you fall asleep, you're inevitably going to leave some behind. You can't count them all! You need to sleep! But those poor imaginary leftover sheep never get to clear the fence and be free. What will happen to them?

Lots of people have a little booze before bed to help them get to sleep — but while a night cap may help in the dozing-off department, too much alcohol can actually do a number on the overall quality of your shuteye. Let's take a look at some of the important differences between drunk sleep and sober sleep, including why it's so damn hard to sleep in after a tipple-tastic night on the town.

Many of us have trouble sleeping in an unfamiliar place, like a hotel, or a friend's house for the first time. When we finally do get to sleep, it's often fidgety and disturbed. New research shows that one hemisphere of our brain stays more active during the first night of sleep — and it does so to keep us ready for trouble.

Video: The scariest place to be when you're a kid? Alone, at night, in your bed, right before you sleep. You just know right when you close your eyes, all the stuff of nightmares is going to come alive and scare any chance of sleep out of you. And it's probably all true! Who knows what's going on around you when you sleep. Andy Kennedy played on that fear by showing sleep disturbances from outside and within in his animated short Slow Wave.
