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.
Because ladybug hindwings are covered by an opaque outer shell called an elytra, scientists were not sure how the wings’ folding mechanism worked until Kazuya Saito created a clear replacement shell that allowed them to film the process in super slow-motion.
Apparently scientists tend to think of themselves as more rational, objective, and intelligent than non-scientists. Makes sense. And laypeople tend to think that of scientists too. But the scientists surveyed in a new study from Tilburg University in the Netherlands apparently see themselves as much more rational, objective, and intelligent than non-scientists. Are they overconfident […]

Learning to code is a perfect way to grow your technical sophistication, and open up a host of new career options. But since most “learn to code” initiatives focus heavily on web development, it can be tough to find good resources for general-purpose computer science outside of a 4-year degree program. To get a broad […]
While many newer smartphones boast decent water resistance, most of us are still stuck with the kind of handsets that need to spend the night in a bowl of rice when they get wet. If you want to enjoy your favorite podcasts in the shower but are holding out for your next phone upgrade, this […]
