Folks who've commented on this video seem convinced that this kitten is having a nightmare. But do kittens really have nightmares, or dreams at all?
Well, the kitten's clearly dreaming. It may not be a nightmare, it may be running after a mouse; we'll never know. Naysayers will say: You can't prove cats dream. But if you measure brainwaves in cats, dogs and several other animals, it's clear that they go through a period of rapid-eye movement, or REM sleep, when the brain is very active. In humans, exactly the same thing happens--and that's when we dream. I read a study that kittens do a lot of this kind of sleeping in their early life, as their brain is developing. And I believe it makes sense that REM sleep is not only associated with the maturation of neurons in the brain, but also with dreaming processes. As kittens begin to sense the world around them, those things can be regurgitated in sleep in the form of dreams.

Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]

You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
